The authors investigated the effects of low-intensity resistance training on muscle size and strength in older men women. Thirty-five participants (age 59–76 yr) were randomly assigned to 2 groups performed (50% 1-repetition maximum) knee-extension -flexion exercises with either slow movement tonic force generation (LST; 3-s eccentric, concentric, 1-s isometric actions no rest between repetitions) or normal speed (LN; concentric eccentric rests twice a week for 12 wk (2-wk preparation 10-wk intervention). LST significantly increased thigh-muscle thickness, as well strength. LN improved strength, but its hypertrophic effect was limited. These results indicate that even individuals, can be an effective method gaining mass
