Muscle morphological changes and enhanced sprint running performance: A 1‐year observational study of well‐trained sprinters.
Numerous cross‐sectional studies have attempted to identify the muscle morphology required to achieve high sprint velocity. Our longitudinal study addressed an unanswered question of cross‐sectional studies: whether hypertrophy of the individual trunk and thigh muscles induced by daily training (e.g...

Our longitudinal study addressed an unanswered question of cross‐sectional studies: whether hypertrophy of the individual trunk and thigh muscles induced by daily training (e.g., sprint, jump, and resistance training) is linked to an improvement in sprint performance within well‐trained sprinters. Twenty‐three collegiate male sprinters (100‐m best time of 11.36 ± 0.44 s) completed their daily training for 1 year without our intervention. Before and after the observation period, the sprint velocities at 0–100 m, 0–10 m, and 50–60 m intervals were measured using timing gates. The volumes of 14 trunk and thigh muscles were measured using magnetic resonance imaging. Muscle volumes were normalized to the participants' body mass at each time point. Sprint velocities increased at the 0–100 m (p < 0.001), 0–10 m (p = 0.019), and 50–60 m (p = 0.018) intervals after the observation period. The relative volumes of the tensor fasciae latae, sartorius, biceps femoris long head, biceps femoris short head, semitendinosus, and iliacus were increased (all p < 0.050). Among the hypertrophied muscles, only the change in the relative volume of the semitendinosus was positively correlated with the change in sprint velocity at the 50–60 m interval (p = 0.018 and ρ = 0.591). These findings suggest that semitendinosus hypertrophy seems to be associated with sprint performance improvement within well‐trained sprinters during the maximal velocity phase. Highlights: Over the past few decades, numerous cross‐sectional studies have attempted to identify the muscle morphology required to achieve high sprint velocity, but the question remains as to whether hypertrophy of the individual trunk and thigh muscles is linked to an improvement in sprint performance within well‐trained sprinters.After 1‐year daily training in well‐trained sprinters, the tensor fasciae latae, sartorius, biceps femoris long head, biceps femoris short head, semitendinosus, and iliacus were hypertrophied.Among the hypertrophied muscles, only semitendinosus hypertrophy was associated with sprint performance improvement within well‐trained sprinters during the maximal velocity phase of the 100‐m sprint. pubtype: Academic Journal doctype: diagnostic images research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
