Significant differences in muscle thickness gains were observed between FPO and FPI conditions.
Understanding these differences can help in designing targeted training programs.

- 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.Strong
- Positioning FPO potentiated increases in medial gastrocnemius head thickness, while FPI provided greater gains for the lateral gastrocnemius head.Strong

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
