Force Generation in Sprint Running Is Related to Muscle Properties in Male Sprinters
نویسندگان
چکیده
The aim of this study was to investigate the relationship between muscle properties (MP) and force production (F) during a sprint running acceleration phase in 18 male sprinters (Age: 24.4±4 years; personal best: 10.66±0.5 s). MP (muscle thickness, fascicle length and pennation angle) of the lower limb muscles were measured by B-mode ultrasonography and F was modelled at each instant by derivation of running velocity. All MP variables showed significant correlations with peak force values (p>0.01): longer fascicle length, greater thickness and lower pennation angle are associated with greater force production and subsequent acceleration ability.

Objective: Lower extremity stiffness is associated with variables such as the frequency and length of running steps, the amount of muscle force and power production. Previous studies showed contradictory findings regarding the relationship between lower extremities joints stiffness and start velocity. Sprint start can be highly affected by two key components of lower limb stiffness, namely, for...

The purpose of this study was to investigate the relationship between muscle fascicle length and sprint running performance in 37 male 100-m sprinters. The sample was divided into two performance groups by the personal-best 100-m time: 10.00-10.90 s (S10; n = 22) and 11.00-11.70 s (S11; n = 15). Muscle thickness and fascicle pennation angle of the vastus lateralis and gastrocnemius medialis and...
