Effects of dehydration on muscular strength and anaerobic performance: a randomized crossover trial
Judelson DA, et al.
Evidence is still building up
Summary
A crossover RCT examining the effects of 1–3% body weight dehydration on isometric and isokinetic muscular strength and anaerobic power. Dehydration of ≥2% body weight significantly reduced strength and power, with maximum strength declining up to 5–8% and muscular endurance also decreasing.
Key findings
- 1
≥2% body weight dehydration reduces maximum muscular strength by 5–8%
- 2
Anaerobic power (sprinting, maximum output) also significantly decreases with dehydration
- 3
Muscular endurance (ability to maintain force across high repetitions) is most susceptible to dehydration
- 4
Mild dehydration (~1% body weight) shows minimal impact within individual variation range
