The Claim
Hypertrophy-type resistance training for 16 weeks is associated with an 8.3% increase in intracellular water in young adult men and an 11.7% increase in intracellular water in young adult women.
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.
After 16 weeks of hypertrophy-focused weight training, young adult men experienced an 8.3% increase in intracellular water, and young adult women experienced an 11.7% increase.
See the scientific wording
Hypertrophy-type resistance training for 16 weeks is associated with an 8.3% increase in intracellular water in young adult men and an 11.7% increase in young adult women, suggesting enhanced cellular hydration and potential improvements in muscle cell volume regulation.
When muscles grow larger from weight training, they make more proteins inside the cells. These extra proteins pull water into the cells, making them swell with water. This increases the amount of water inside the muscle cells and improves how well the cell membrane holds electrical charge.
What the research says
1 studyStudy: Hypertrophy-type Resistance Training Improves Phase Angle in Young Adult Men and Women
This study found that lifting weights for 16 weeks made muscle cells in both men and women hold more water, which is a good sign their muscles are getting stronger and healthier.
