Foot positioning during calf training affects gastrocnemius muscle thickness, with FPO leading to an 8.4% increase in medial MT and FPI leading to a 9.1% increase in lateral MT after 9 weeks.
Trainers can optimize calf training by adjusting foot positioning to target specific muscle heads.
StrongSupportsmedium confidence
After the training period, there were observed increases in MT of both medial (FPO = 8.4%, FPI = 3.8%, and FPF = 5.8%) and lateral (FPO = 5.5%, FPI = 9.1%, and FPF = 6.4%) gastrocnemius heads.
Why this rating
The study involves a controlled training program with measurable outcomes.
