Resistance Training Study

Randomized, double-blind, placebo-controlled; 48 healthy, elderly men (aged 66-78 years).

Results: Mean abdominal fat mass value was significantly lower in the resistance training + HMB group compared to the no training + placebo, no training + HMB and resistance training + placebo.*1

Experimental Bed Rest Study

Prospective, randomized, double-blind, placebo-controlled; 24 healthy, older adults on on experimental bed rest (aged 60-79 years).

Results: Supplementation with HMB preserved lean body mass in older adults during 10 days of bed rest compared to control.*2

Improved total fat mass and muscle quality*

Two Phase Isokinetic Leg Extension Study

Double-blind, placebo-controlled trail in two phases; healthy, older adults (aged 65+ years).

Results: Phase 1- HMB supplementation improved isokinetic leg extension and total lean mass, leg lean mass and leg extension compared to baseline.* Phase 2- HMB supplementation improved total fat mass and muscle quality compared to baseline.*3

Decreased markers of muscle overexertion*

Prolonged Run Study

Randomized, double-blind, placebo-controlled; 16 runners (running at least 30 mi/wk)(aged 20-50 years)

Results: After a prolonged run, the placebo group showed increased creatine phosphokinase activity compared to the HMB supplemented group.* Also, the HMB supplemented group showed decreased lactate dehydrogenase activity compared to the placebo group.*4

 increased upper body strength*

Bench Press and Leg Press/Extension Study

Randomized, double-blind, placebo-controlled trial in two-gender cohorts; 82 men and women (aged 20-40 years).

Results: Individuals receiving HMB supplementation exhibited a greater increase in upper body strength compared to placebo.Supplementation group had increased fat-free weight and decreased percent fat.*4
