Ankle taping and strapping in soccer: do ankle supporting techniques affect agility?
Peter Carey
Abstract
This research project aimed to investigate the effects of external ankle supports on agility in the
uninjured soccer player. Twenty-six amateur soccer players (twenty-two male and four female),
without any previous lower limb injuries, performed three Illinois agility course runs per control group.
All testing was preceded by a familiarisation session. Participants were randomly assigned a
predetermined sequence of variable experiences via the Latin square to ensure randomisation. The
support groups used were: Tape Support Group (TS) (using a three-layer closed-basket weave ankle
taping technique with heel locks; the tape was none-elastic and closure was completed with
elasticated tape.) A Re-usable Elasticated ankle support group (RES) (using a Lonsdale Elastic Ankle
Support) and a control group with No Support applied (NS). Participants were not informed of the
purpose of the study to ensure blinding. The Illinois agility run was completed three times per variable
and a mean score was calculated. No significant agility effects of any ankle support was observed
(p=<0.814) when compared to the control group. External ankle supports do not significantly affect the
agility of the uninjured soccer player and therefore agility performance cannot be influenced either
positively or negatively.
Introduction
External ankle supports are a frequently used intervention in the sporting world. Ankle supporting is
used to prevent injury and support the joint after a trauma. There is disagreement and conflicting
opinions regarding the usefulness of ankle supports in current research. Many discussions amongst
Sports Therapists and Athletic Trainers explain their use as a prophylactic intervention (preventative
treatment) and use them to improve performance. Current research provides inconclusive evidence
that ankle supports effect performance. Despite this, many therapists and players continue to use
taping and bracing at the ankle joint to prevent injury and to aid performance. This highlights a need
for more research in this field to try and establish if ankle supports have a positive or negative effect
on athlete’s performance and injury prevention within sport.
Review of the Literature
Prevention of Injury
Raymond, Nicholson, Hiller, and Refshauge (2012) do support the use of ankle taping for injury
prevention but state that this is not due to an increase in proprioception. Re-usable ankle supports are
also advised to be a useful prophylactic intervention method to prevent injury in high-risk sporting
90
activities (Handoll, Rowe, Quinn and DeBie, 2008). Other research also suggests that different types
of ankle supports provide additional structural support and improvement during injury (Boyce, Quigley,
& Campbell, 2005). The study by Quackenbush et al (2008) showed that there is still adequate
support provided by ankle taping despite its loosening during activity; which still provided injury
prevention properties. This does not correspond with the findings by Abian-Vicen et al (2008) who
believe that taping of the ankle could increase the risk of injury due to decreased range of motion
leading to an increased peek force on landing.
Ankle Supports
Basket-Weave
Wilkerson (1991; cited in Abian-Vicen et al, 2008) explains that the closed-basket weave ankle taping
technique was designed to restrict ankle inversion in the uninjured athlete. The closed basket weave
ankle taping technique was stated as being a frequently used supporting technique for the ankle that
encompasses the entire joint and was shown to be the most stable form of ankle support. (Abian-
Vicen et al, 2008; Ratick et al, 1962 cited in Constantinou & Brown, 2010).
Basket-weave ankle taping is claimed to provide the greatest level of strength and continuity at the
ankle (Hyde & Gengenbach, 2007). These positive reviews of the technique have led to its popularity
in studies such as those by Riley & Atkinson (2009), Sanioglu et al (2009), Hyde & Gengenbach
(2007), Wilkerson (1991; cited in Abian-Vicen et al, 2008) and MacDonald (1994, cited in Riley &
Atkinson, 2009).
Re-Usable
It was found that the re-usable ankle supports and semi-rigid supports have injury prevention
properties in the study by Tang, Wu, Liao, and Chan (2010). Here, the semi-rigid, re-usable was
found to reduce supination angular displacement and their conclusion supported the use of reusable
braces as a prophylactic brace.
Cordova et al (2010) used re-usable ankle bracing to examine any affects it had on the lower
extremity. Athletic tape and braces were found to reduce ankle range of motion equally. This study
supports the use of re-usable bracing due to costs. This reduction in range of motion is strongly
considered to be an injury prevention technique (Hume and Gerrard, 1998). Hume and Gerrard
(1998) state that there is no reduction among Rugby Union players using external ankle supports. A
limitation exists here because their statement generalised the abilities into the category of
‘performance’. Strength is said to improve with ankle supports in the study by Hyde and Gengenbach
(2007) but vertical jump performance was found to decrease in the study of Taekwondo athletes by
Sanioglu et al (2009). This disagrees with the statement made by Hume and Gerrard (1998).
91
Athletic Tape
Bot et al (2003) concluded from a meta-analysis that two studies did show how athletic taping allowed
participants to complete agility courses faster. This would indicate possible advantageous effects of
athletic taping on agility but ten other studies reported no effect and three others reported that agility
performance decreased. Ambegaonkar et al (2011) found that athletic tape hindered agility but had no
effect on balance or jump performance. Sanioglu et al (2009) however, found that using the closed
basket-weave ankle taping technique with athletic tape decreased vertical jump performance. The
non-elastic properties of the tape may have caused a restriction in range of motion (which would
compromise the muscles ability to operate throughout the full range of the articulation) and therefore
allow less momentum and force to affect the movement. However, the reduction in range of motion
may increase joint stability which could aid balance. It would therefore be unsuitable to conclude that
athletic taping can positively or negatively affect agility as balance and jump are both components of
agility (Sheppard & Young, 2006).
Kinesiotape
A study of kinaesthetic taping by Csapo et al (2012) found it did not affect drop-jump performance nor
muscle endurance. There is a similar study to that by Bicici et al (2012) who also look at kinaesthetic
tapings effects on functional performance of Basketball players. The participants completed testing
four times with a different variable applied each time - a placebo tape, no tape, athletic tape and
Kinesiotape. It was found that athletic taping of the ankle joint decreased performance in standard
heel rise and vertical jump tests. Athletic tape was shown to have no other significant effects. Bicici et
al (2012) disagrees with the findings of Csapo et al (2012) because here, strength was found to
increase.
Spatting
Spatting is an ankle supporting technique that involves applying athletic tape to the ankle over the
players’ footwear (Reuter, Dahl & Senchina, 2011). In the study by Reuter et al (2011) it was
discovered that ankle spatting had no additional benefits or drawbacks in terms of athlete
performance during agility tests.
Performance Factors
Speed
Bot et al (2003) critically reviewed eighteen studies from 1988-2003, to find that the majority of studies
concluded that ankle taping had little or no effect on any aspects of performance. A study by Hume
92
and Gerrard (1998) looked at ankle taping and bracing to see if performance could be affected. The
research found ankle taping was unable to affect speed, and concluded that their research provided
no evidence of performance enhancement.
Agility
A study by Ambegaonkar et al (2011) found that ankle supporting increased agility run completion
times. The study found that ankle supports hindered the participant’s ability to perform quick
directional changes as well as not affecting balance or jump performance. This study is argued by
Jerosch and Schoppe (2000) who found that ankle supports improved agility in injured athletes.
Vertical Jump
Abian-Vicen et al (2008) found that ankle taping has almost no effect on jump performance in healthy
participants; a claim supported by Hume and Gerrard (1998). In a study involving taekwondo athletes,
Sanioglu et al (2009) found that vertical jump performance decreased with ankle taping. The closed
basket-weave taping technique was used here.
Quackenbush, Barker, Stone-Fury and Behm (2008) compared a group who received ankle taping
supports to a group receiving no supports. Findings showed that vertical jump performance did not
differ between the groups. Bicici et al (2012) disagreed with this by concluding that athletic taping of
the ankle joint showed a decrease in vertical jump performance. Bot et al (2003) concluded that there
are no clear benefits of using ankle supports to improve vertical jump performance but some studies
(Ambegaonkar et al, 2011) have found that ankle supports can influence vertical jump performance.
Strength, Power and Endurance
Other factors that can influence agility are strength and power (Sheppard and Young, 2006). Kenny et
al (2011) concluded that taping of the ankle joint does not affect strength and power. Csapo et al
(2012) found that isometric strength could be improved at the ankle joint with kinaesthetic taping
supports applied, but only when the ankle is in a state of full dorsi-flexion. This conclusion suggested
that kinaesthetic taping is only effective at the end of joint range and may not have influencing
properties in smaller soccer-specific movements.
Range of Motion
Another factor that can influence agility is range of motion (Sheppard and Young, 2006).
Quackenbush et al (2008) stated that ankle taping was effective at reducing range of motion although
loosening of the tape was found during sustained activity.
93
If agility is negatively affected by ankle supports, as suggested by ten studies in the review by Bot et
al (2003), this could be caused by the restriction of the ankles range of movement which could restrict
the muscles function and ability to contract through the full range.
Purcell et al (2008) conducted a study of three ankle taping conditions (white cloth, adhesive tape and
no tape) and their effects on range of motion. Findings concluded that the adhesive tape was more
effective as it maintained range of motion restrictions when the cloth tape had failed. The study does
not mention if restriction of range of movement is beneficial.
Other studies show range of motion reduction using semi-rigid, re-usable ankle supports (Zhang,
Wortley, Silvernail, Carson & Paquette, 2012). The reduction resulted in a greater peak eversion and
plantar flexion motion during landing. As studies suggest, this restriction is thought to be effective at
injury prevention and protection, due to the reduction in movement and the structural integrity
increases at the ankle (Raymond et al, 2012; Chang et al, 2010: Boyce et al, 2005). It is apparent that
there is an increase in load and peek forces through the ankle joint when supports are applied, which
may lead to an increased risk of injury, providing a contra-indication to this prophylactic support.
Stability
Lohkamp, Craven, Walker-Johnson, and Greig (2009) investigated whether ankle taping can have
any effect on ankle stability. They found that it is possible that the tape can increase ankle stability
which aids performance, but the effectiveness of the tape diminishes with exercise during soccer
specific activities. The study concluded that there was no significant advantage of taping within the
first twenty two and a half minutes of activity but did observe that reaction times increased with
extended activity durations. Despite this, research concluded that any potential benefit is negated
after fifteen minutes, including ligamentous support due to loosening of the tape.
Diminishing support effects during activity
More research into ankle taping is found by Reuter et al (2011) who looked to see if ankle taping,
bracing and spatting had any effect on performance during maximal effort sprint drills. The study
found that the participants perceived that having no tape applied was the least stable, indicating
participant’s preconceived bias, which of course could affect their performance and results. A
qualitative study of ankle supports may be beneficial in future research to better understand this
possible effect. Reuter et al (2011) found that the prophylactic benefits of ankle taping decreased after
just fifteen minutes of activity. These findings agree with Lohkamp et al (2009) who also state that
taping benefits diminish but only after twenty two and a half minutes of exercise. Although the study
by Reuter et al (2011) cannot support the use of ankle spatting because the results are clinically
insignificant, they do conclude that, due to costs, a reusable brace is advised because it is more cost-
effective and is equally effective as taping and spatting.

Neurological
Balance
Balance and proprioception are considered some of the most key components of agility and co-
ordination skills (Sheppard & Young, 2006; Kostopoulous, Bekris, Apostolidis, Kavroulakis &
Kostopoulos, 2012). A study by Kenny, Wu, and McEvoy (2011) found that ankle joint taping was
found to neither interfere with, nor enhance balance performance. Knight and Weimar (2012)
contradict and find that single leg balance is actually negatively affected by taping but did find that it
affected double leg balance. This contradicts findings of Ambegaonkar, Redmond, Winter, Cortes,
Ambegaonkar, Thompson, and Guyer (2011), who found balance was not affected by ankle taping at
all.
The studies by Kenny et al (2011) and Ambegaonka et al (2011) did not look at single leg balance
which could be why they have conflicting results. However, both studies are in agreement that double
leg balance is not affected while Knight and Weimar (2012) reports that negative effects are present.
Chang et al (2010) observed no benefits of ankle taping on standing balance. Interestingly, these
findings indicated that ankle taping improved balance on unstable surfaces, suggesting that the
workload on the ankle can determine the influence that tape has. Abian-Vicen et al (2008) and
Ambegaonkar et al (2011) conclude that ankle taping has no effect on balance. Conflicting literature
makes conclusion impossible.
Proprioception
Proprioception is the nervous system providing sensory information to the brain and spinal cord about
movement and position which plays a vital role in agility (DeLisa and Walsh, 2005). Halseth,
McChesney, DeBeliso, Vaughn, and Lien, (2004) conducted a research project to see if taping could
improve proprioception at the ankle joint. The primary research focus was to see if kinesio-taping
could have an effect on ankle performance compared to a no-tape control group. The results showed
no significant difference between the taped group and the control group and conclusions that
kinesiotape is not likely to enhance ankle proprioception were made. Raymond et al (2012) looked at
ankle tapings effect on proprioception in people with a history of ankle instability via a meta-analysis.
Raymond et al (2012) concluded that ankle taping did not affect proprioception. This contradicts the
opinion of Chang et al (2012) who state that proprioception and range of motion at the ankle will be
affected more on unstable surfaces.

Illinois Agility Run
It is apparent that a valid agility test should encompass as many components of the sport for which it
is testing; as described by Sheppard and Young (2006). The Illinois Agility Test was found to
encompass more aspects and movements that are involved in Soccer while being a widely used and
valid test of agility that has been proven over the decades (Gambetta, 2007). The test involves speed,
acceleration proprioception and reaction to a stimulus, as well as balance, power, rapid directional
and velocity changes (Sheppard & Young, 2006). Kutlu et al (2012) note that the Illinois Agility Test is
a good measurement tool to choose because it requires little learning, therefore reduces any effect
repetition could have on results. The test also uses multi-directional movements lending to reasoning
that bias may be removed by ensuring the test is bilateral. (Hoffman et al, 2007).
Methodology
All ethical permissions were sought and consideration taken to anonymise participants throughout the
research.
Subjects
Twenty six mixed ability amateur football players (nineteen males and seven females) were recruited
from local football (soccer) teams to participate in the study. (Mean values: Height 176.7cm, Weight
76.6kg, Age: 25.5 years.) Participants screening was completed prior to the study and participants
with any pre-existing lower limb injuries within the previous twelve months, or participants with chronic
injuries affecting their ability to complete agility runs were excluded.
Study Design
The study was a quantitative design with repeated measures (ANOVA.) To eliminate personal bias,
subjects were not given details of what the study was measuring or testing. All supports were applied
by the same therapist and all run timing was performed by the same person.
Subjects were briefed with session instructions and participants had their relevant support variable
applied as per the results of the randomisation technique employed to randomise taping application
and prevent familiarity. The conditions were: The Closed Basket-weave Ankle Taping Technique with
Heel Locks (TS), Re-usable Elasticated Ankle Supports (RES) using a Lonsdale Elasticated Ankle
Support or No Support (NS).
All testing was conducted in an indoor sports hall to negate fluctuating factors such as weather,
temperature (19°C), surface friction, surface integrity (wood) and lighting. Testing was carried out over
four sessions; the first being a familiarisation session, to help reduce the learning effect.
96
The warm-up was based on research by Samson et al (2012) and consisted of five minutes of running
followed by dynamic stretching. The stretching movements were completed through hip extension
(forward lunge walk), hip flexion (straight leg walk and knee-ups), abduction and adduction (side
lunge walks), knee flexion and extension (knee heel-to-gluteal kicks; each side), trunk circles and
ankle rotations. All movements were taken through the full range of motion for three sets of thirty
repetitions each. Run times were recorded using manual stopwatches by the same therapists for each
session and the participants ran the course individually. Participants completed the Illinois Agility
Course. The mean times of the three agility runs were taken to ensure that all effects were
considered.
Following completion of the runs, participants performed a cool-down consisting of a five minute run
followed by static stretching of the hamstring, quadriceps, abductor, adductor and calf muscle groups
as advised in the standard model by Schnitzer and Trela (2012). Each stretch was held at the end of
the range for thirty seconds each and once completed; the participants then had their supports
removed if applicable.
Tape and taping technique used
Five centimetre wide, Vulkan® none elasticated, and seven and a half centimetre wide, Vulkan®
elasticated tape was used in condition one (TS). The closed basket weave with heel locks was
applied with none elasticated tape and closing off was applied with elasticated tape. (See Figure: 1).
Application began by applying Mueller Tuffner® Pre-Tape adhesive spray to the area. Two Lewis-
Plast® heel pads were then placed over the Achilles tendon and the tibiotalar join areas to provide
protection. A layer of Mueller® seven centimetre wide, pre-wrap was applied followed by two anchors
that were then placed just under the belly of the gastrocnemius muscle. Stirrup taping techniques
where then alternated with horse shoe taping techniques until they had both been applied three times
each; creating the closed basket-weave. Two heel locks where then applied. The taping was then
closed off by enclosing the support with horizontal strips of elasticated tape. This technique was
applied to both ankles.
97
Figure 1: Taping Ankle Support
The other condition involved an elasticated reusable ankle supports. (See figure 2). These Supports
were also applied by the same therapist to both ankles. The support application began on the by
placing the in-build looped over the foot. The support was taken from the lateral foot to the medial
ankle were it passed around the Achilles tendon area. It then passed from the distal posterior tibial
area to the medial aspect of the foot. Once more, it passed under the foot and back to the medial
aspect of the ankle. The support then completed one horizontal loop around the distal tibial area and
secured via Velcro.

Results
Using SPSS software a repeated measures ANOVA was used involving three variable conditions,
consisting of a Tape Support group (TS), a Re-usable Elasticated Support group (RES) and a control
group with No Support (NS).
Using SPSS; the Mauchly’s Test of Sphericity revealed a p value of >0.547 which indicated an
insignificant difference between variables. The Greenhouse Geiser results also show how the study
could not find any significance effects of the variables on agility; (F(1.903,45.664) = 0.193, p= <0.814,
partial η² = 0.0008).
98
When gender was considered in the analysis of results, there was a greater significance between
variables but not enough significance to conclude that supports affect agility. The Mauchly’s Test of
Sphericity showed a low significance of >0.580 as did the Greenhouse Geiser: (F(1.903,45.664) =
0.881, p= <0.417, partial η² = 0.0035). Statistical analysis does not provide significant evidence that
agility was affected by the variables. The effect size was very small, indicating no difference between
the mean values. Also, there was no significant differences found between variables (regardless of
gender consideration) and therefore, a post-hoc test was not required.
Figure 3 gives each participant’s results and shows how the variables affected individual
performances. Figures 4 and 5, displays the insignificant results from SPSS analysis. Figure 4 shows
the combined run times for each group while figure 5 shows the combined mean scores of each
group. The visual representation of results allows the differences to be observed which were not
possible using SPSS because of the lack of a post-hoc analysis.

Discussion
The Illinois Agility Test was found to be the most relatable to soccer in the current literature (Draper &
Lancaster, 1985, cited in Sheppard and Young, 2006; Cureton, 1951, cited in Sheppard and Young,
2006; Hastad & Lacey, 1994, cited in Sheppard & Young, 2006; Asadi, 2012; Hoffman et al, 2007;
Gambetta, 2007 & Kutlu et al, 2012). There were no significant relationships found between each
variable and agility times. When results considering gender were analysed, no significant

relationships could be discovered. SPSS was used to analyse the results and neither the effect size
nor the power indicated any influence of ankle supports on agility. The present data supports the
findings of other research which state that agility is not affected, either positively or negatively, by any
type of external ankle support. (Hume & Gerrard, 1998; Rosenbaum et al, 2005 and Reuter et al,
2011)
Figure 3 shows individual run times. It can be observed that the Tape Support (TS) group
outperformed the other conditions nine times, Re-usable Elasticated Support (RES) outperformed
other groups six times and the No Support group (NS) eight times. The graph also shows that the
differences between each of the groups are minimal. However, it can be observed that the RES
group was more frequently slower than the others with this being the case eleven times (more than
TS at six and NS at seven).
More differences can be observed in Figures 4 and 5, but again they are not large enough to be
considered significant. Here, the results show that the RES group performed slower when looking at
both mean results and total results, even though the differences are small. Ambegaonka et al (2011)
found that re-usable ankle supports negatively affect agility. A study by Bot et al (2003) suggested
agility is improved with ankle supports but then concluded differently by stating that the supports had
no significant influence because only two of the eighteen articles were found to allow participants
(with functional ankle instability) to complete an agility course faster. The results displayed in figures 4
and 5 agree with that research but show that both support groups failed to outperform the NS group
but only with a p value of <0.814. Bot et al (2003) highlighted insignificant trends in much the same
way as this study.
A greater correlation is present with the studies that suggested that no effects of ankle supports were
present (Rosenbaum et al, 2005; Cordova et al, 2010 and Hume & Gerrard, 1998). Hyde and
Grengenbach (2007) stated that strength improved with ankle supports. There is no evidence in this
research project to support this claim, but as strength was not individually observed, any strength
increases may have been masked by decreases in other factors affecting agility. Other such factors
that can affect agility are balance and proprioception (Sheppard & Young, 2006). Taping or re-usable
ankle supports were found to have no effects on balance according to Kenny et al (2011), Hardy et al
(2008), Ambegaonka et al (2011) or Chang et al (2010). However, the study cannot conclude with any
significance that the supports negatively affected balance or agility which leaves it in disagreement
with Knight and Weimar (2012). Chang et al (2012) found that proprioception may be improved with
ankle supports on unstable surfaces. As this study was completed on a stable surface to control
limitations, it may be acknowledged that, in a genuine soccer environment, the surface may be
unstable and ankle supports may have then affected proprioception agility.
In the studies that concluded that ankle supports had influential properties; different agility tests where
used including the Shuttle Run and the Figure of Eight agility test (Bot et al, 2003). Ambeogonka et al
101
(2011) found that agility was negatively affected with ankle supports, used the Right Boomerang
agility test. It is possible that using a different agility test could produce different results based on the
findings of these research articles. The study by Rosenbaum et al (2005) also used a different agility
test (which was a custom agility course involving many factors of agility) and found that ankle
supports could not positively or negatively influence agility. Results from SPSS analysis find this study
in agreement with this research, with agility neither being positively or negatively affected.
Furthermore, no significant differences were found between the types of variables. Figures 4 and 5
both show how differences between the variables are insignificantly similar.
Limitations
This study only involved participation from Soccer players. A study looking at different participants
may produce alternative results. The conclusion is only applicable to the particular age range of
participants used in this study. The mean age was 25.46 years. All participants in this study were
uninjured. Some studies found that injured participants reacted differently to ankle supports (Haldeth
et al, 2004 and Raymond et al, 2012). Conclusions are therefore limited and are only applicable to
uninjured participants.
Reaction times of participants may affect the results and provided a limitation to this study. A
countdown allowed the participants to anticipate the start command; reducing reaction time
influences.
Participants in this project also gained more experience of the course as they completed variables;
which may have influenced their results due to the learning effect. The Illinois Agility Run was
acknowledged as a valid agility test that is the least influenced by learning effects (Kutlu et al, 2012).
This study used an unequal sample size (nineteen males and seven females.) Body structures may
cause males and female to react differently. It is possible that female ligament laxity is increased
during menstruation and would therefore affect agility (Heitz, Eissenman, Beck & Walker, 1999). The
effects of this were not considered during the study and may have altered female performance and
results.
Sources of Error
Although every measure was taken to ensure taping was applied equally to each participant, a
possible source of error exists here. Taping may have been unequal because of possible differences
in length, position, and tension of the tape between participants and between ankles.
Timing of the runs was not completely accurate due to the stopwatch operator having a poor reaction
time and judgement being done by eye. Course completion was achieved in a short duration and split
102
seconds become more influential, which allows the use of stopwatches to be scrutinised as mean
scores were given to two decimal places. Future research may consider using electronic timing gates
increase measurement accuracy.
Conclusion & Recommendations
Neither re-usable, elasticated ankle supports nor the closed basket-weave ankle taping technique
with heel locks significantly affected agility in the uninjured Soccer player during the Illinois Agility Test
(p=<0.814). When the results were analysed considering gender; more significance was present
(p=<0.417). The effect of gender was not analysed in this study and future research should consider
this. It was also observed that participants made regular comments about how the RES was
uncomfortable. Reuter et al (2011) stated that their participants reported ankle spatting felt
uncomfortable but also more stable. Therefore psychological influences of ankle supports may be
studied in a qualitative study to determine how they affect run times.
As the Illinois Agility Test is only short in duration, it may be considered that group variations cannot
be fully observed within a short time frame. A longer agility test may also provide a more suitable test
for Soccer athletes due to the normal time period of a match and because taping loosens over time
(Quackenbush et al, 2008).
The results of this research project showed that there are no significant effects of ankle supports on
agility using a stable surface. However, Chang et al (2012) found that proprioception can be affected
on unstable surfaces. Proprioception was stated to be a performance factor in agility (Sheppard &
Young, 2006). Future studies may also wish to look into surface integrity in their research.
