INTRODUCTION: Exercise countermeasures for long duration space crews incorporate aerobic and resistance exercise (i.e., concurrent training). Microgravity simulation studies show that resistance exercise alone can be completely effective at preventing muscle loss, yet crews return from missions with reduced muscle mass and function. Some Earth-based studies show human skeletal muscle ...

Aging is associated with lower muscle mass and an increase in body fat. We examined whether creatine monohydrate (CrM) and conjugated linoleic acid (CLA) could enhance strength gains and improve body composition (i.e., increase fat-free mass (FFM); decrease body fat) following resistance exercise training in older adults (>65 y). Men ...
