It has been suggested that certain lower leg variables affects running and jumping performance.However, it is unclear how these interact with each other, they jointly affect hopping performance.We assume AT-MA influences the physical performance differently depending upon biomechanical of plantar flexor muscles.We hypothesize no single variable can explain height, rather a combination variation in height.Healthy young adults (n = 28, age 21.8 ±4.0 yrs) performed serial hops on force plate during which we recorded right joint kinematics, lateral gastrocnemius fascicle behavior, electromyography activity.We found correlation between height p=0.14).Multiple regression analyses revealed variations AT-MA, ankle dorsiflexion amplitude, peak ground reaction explained 53% height.We concluded even selected only moderately account for performance.
