DEVELOPMENT OF AN ECCENTRIC CYCLING PARADIGM TO PRODUCE
DELAYED ONSET MUSCLE SORENESSFredrick Peters1, Sara Harper1, John McDaniel1, Angela L. Ridgel1
Presented by: Fredrick Peters
Background
• Delayed onset muscle soreness (DOMS) - sensation of pain in the skeletal muscles following eccentric physical activity (Kedlaya, 2014).
• Results in: (Cheung et al., 2003, Baird et al, 2001)– Reduced blood supply– Pain and inflammation– Increased creatine kinase (CK) activity– Muscle weakness – Decline of range of motion (ROM)
Purpose
• The main objective of this investigation is to determine if a customized eccentric cycling paradigm can be used to produce symptoms of DOMS.
Eccentric Paradigm
• This paradigm consists of forward resistance to backward pedal motion on a motorized cycle
Methods
Eleven recreationally active men (18 - 40 years old) completed five minutes of eccentric cycling.
Measurements taken at four time points:•T0 – Friday (baseline)•T1 – Monday (Eccentric cycling) •T2 - Tuesday (24 hours post-cycling)•T3 – Wednesday (48 hours post-cycling)
Conclusions / Future Direction
• Eccentric cycling paradigm elicits increases in CK and pain scores that peaked between 24-48 hours post-cycling.
• Lactate peaked immediately after eccentric cycling.
• Findings suggest that this eccentric cycling paradigm can be used to elicit markers of DOMS in just five minutes.
• Future studies will use this paradigm to examine the effects of segmental vibration therapy (or other therapies) on recovery from DOMS
