This randomized 2 × 3 factorial trial investigated the effects of protein targets on resistance training (RT) and concurrent training (CT) in 108 middle-aged and older women. The study found no significant interaction between training conditions and protein targets for skeletal muscle mass. However, CT resulted in lower body fat percentage and higher estimated VO₂max compared to RT, while RT improved leg-press strength.
Key findings
- CT resulted in a lower baseline-adjusted week-12 body fat percentage compared to RT, with an adjusted difference of -2.04 percentage points.
- RT showed a higher baseline-adjusted week-12 leg-press estimated 1-RM than CT, with a difference of -6.68 kg.
- CT had a higher baseline-adjusted week-12 cycle-derived estimated VO₂max than RT, with an adjusted difference of 4.53 mL·kg -1 ·min -1.
Why it matters
Understanding the impact of different training modalities and protein intake on body composition and performance in older women is crucial for developing effective exercise and nutrition strategies to enhance health and fitness in this population.
