Macro partitioning

Supplementing resistance training with defatted peanut protein (35g protein/day) significantly increases vastus lateralis muscle thickness and knee flexion torque in older, untrained adults compared to resistance training alone.

If you are over 50 and new to resistance training, adding 35 grams of defatted peanut protein daily to your routine can help you build more muscle in your thighs and increase your knee flexion strength compared to training alone. Stick to a twice-weekly full-body resistance training program focusing on progressive overload.

There was, however, a significant increase in VL thickness in PP versus CTL participants when the 6- and 10-week cohorts were pooled (interaction p=0.041). There was also a significant increase in knee flexion torque in the 10-week PP group versus the CTL group (interaction p=0.032).

Why this rating

Randomized controlled trial with a relatively small sample size (n=39) and short duration (6-10 weeks), limiting generalizability.
