The Claim
In untrained collegiate women, 8 weeks of resistance training is associated with a significant decrease in percent body fat by 1.3% and intracellular water by 0.43 L, regardless of whether moderate-load or high-load protocols are employed.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In untrained female college athletes, 8 weeks of resistance training leads to a 1.3% reduction in body fat and a 0.43 liter decrease in intracellular water, whether they use lighter or heavier weights.
See the scientific wording
In untrained collegiate women, 8 weeks of resistance training is associated with a significant decrease in percent body fat (1.3%) and intracellular water (0.43 L), regardless of whether moderate-load or high-load protocols are used, suggesting that reductions in adiposity and fluid shifts may occur independently of training load intensity.
When muscles are worked to fatigue during resistance training, they grow larger and change how they use energy. This causes the body to burn more fat for fuel and move water from inside muscle cells into other areas, lowering body fat percentage and reducing fluid inside cells.
What the research says
1 studyNew to lifting? Whether you use light or heavy weights, after 8 weeks you’ll likely lose a little body fat and have slightly less fluid inside your muscles—both happen either way.
