IntroducHon


•  Characterize the HR, Lactate, RPE, and VO2 response

•  Training vs compe==on •  Systema=c observa=on •  Nutri=onal analysis


Characterize the HR response in rela=on to body posi=on and face immersion during solo compe==ve rou=nes

Aim


Methods Subjects 8 elite synchronized swimmers (n = 11 solo rou=nes) Age 20.8 ± 4.9 years; height 166.9 ± 9.7 cm

The study was conducted at the Spanish Open Championships

Approved by the Ethics CommiTee and by the Refereeing and Organizing CommiTees

Mixed Methods: Quan=ta=ve (HR) and qualita=ve variables (body posi=on and breath holding status) were simultaneously obtained

Study design


Beat by beat HR was measured using a waterproof heart rate monitor (CardioSwim, Freelap, Switzerland) Data were interpolated: every 0.04s for each video frame (25 fps) using Matlab (Mathworks Inc., USA)

HR monitoring


Using a digital video camera (Panasonic AG-‐DVX100BE 3-‐CCD) Video recording

Recording instrument: LINCE soeware (Gabín, Camerino, Castañer, & Anguera, 2011)

Observa=on instrument ad hoc: 1) face immersion: face-‐in (FI), and face-‐out (FO) 2) body posi=on: horizontal, upright, and inverted.

Validity: was determined according to its conceptual consistency and robustness (consensus opinion of SS experts)

Reliability: Inter and intra-‐observer (kappa values >0.90)

ObservaHonal instrument


RESULTS Heart rate response during a solo rouHne -‐ synchronized swimming


HR Routine time (beats·min-1) (%) Routine Solo 152,3 ± 30,6 100% 204,7 - 20,0 Face In 150,1 ± 31,7 * 62,2% 204,7 - 20,0 Face Out 156,1 ± 28,0 37,8% 200,9 - 24,8 Horizontal 156,0 ± 27,6 + 27,9% 204,7 - 23,4 Inverted 147,4 ± 33,6 40,5% 200,4 - 20,0 Upright 155,2 ± 28,1 31,5% 200,9 - 24,7

Heart Rate & Body PosiHon vs Breath Holding

* p<.0001 Wilcoxon Two-Sample Test

Values: mean ± SD (max -‐ min)


FI routine FI mean FI max n (s) (s) Free + Technical Solo (n=11) 24,5 ± 8,9 4,3 ± 1,2 21,7 ± 4,4 41 - 13 6,2 - 2,6 27,8 - 16,0 Free Solo (n=6) 30,0 ± 7,6 3,9 ± 1,1 22,8 ± 3,9 41 - 20 5,6 - 2,6 27,8 - 16,2 Technical Solo (n=5) 17,8 ± 5,1 4,9 ± 1,1 20,4 ± 5,0 25 - 13 6,2 - 3,2 27,5 - 16,0

Breath Holding

Values: mean ± SD (max -‐ min) FI = Face Inmersion


"   First study in which the HR has been related to breath holding and body posi=on during SS compe==ve rou=nes

"   HR is characterized by progressive, sustained tachycardia, with interspersed periods of intense bradycardia related both to the breath holding periods and to changes in body posi=on.
