Study Finds No Superiority in Timing Resistance Training for Older Adults' Muscle Adaptation
A recent randomized controlled trial investigated whether aligning resistance training with an individual's peak performance time offers superior skeletal muscle adaptations in older adults compared to training at their trough time. The study, which involved 108 participants with a mean age of 67 years, divided them into three groups: training at peak time, training at trough time, or a non-training control group. Over a 12-week intervention period, participants in the training groups completed two supervised whole-body resistance training sessions per week, alongside one moderate-intensity endurance cycling session. The primary outcome measured was isometric midthigh pull strength, with secondary outcomes including handgrip strength and appendicular lean mass index. The findings indicated that effect estimates between the peak and trough training groups were close to zero across all outcomes, with confidence intervals overlapping zero. This suggests no clear differences in skeletal muscle adaptations base...
