Older men with muscle loss who take collagen supplements during strength training lose more body fat (5.4 kg) than those taking a placebo (3.5 kg).

Scientific Claim

In elderly men with sarcopenia, 12 weeks of resistance training combined with 15g/day collagen peptide supplementation reduces fat mass by 5.4 kilograms, which is significantly greater than the 3.5 kilogram reduction observed with placebo supplementation.

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

definitive

Can make definitive causal claims

Assessment Explanation

The study design allows causal claims, and the significant difference supports the use of 'reduces' as a definitive statement.

Similar Assertions

Older men with muscle loss who do strength training and take collagen supplements gain more muscle mass (4.2 kg) than those taking a placebo (2.9 kg).

98%

When older men with muscle loss take collagen supplements during strength training, gaining muscle is more closely linked to losing fat compared to those taking a placebo.

94%

Strength training boosts bone mass in older men with muscle loss, but adding collagen supplements doesn't make it better than just training alone.

82%

Middle-aged men doing strength training and taking this collagen supplement lose 1.9 kg more body fat than those taking a placebo.

76%

Middle-aged men doing strength training and taking this collagen supplement build 1.6 kg more muscle than those taking a placebo.
