The Claim
After 8 weeks of velocity-based back squat training at 65–75% of one-repetition maximum with 20% velocity loss, male and female collegiate athletes with matched relative strength experienced significant improvements in lower-limb maximal strength, jump performance, sprint speed, and rectus femoris muscle thickness, with males showing greater gains in strength and vertical jump metrics and females demonstrating larger improvements in 30-meter sprint performance.
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 8 weeks of a specific strength training program using velocity-based back squats, both male and female collegiate athletes improved their leg strength, jumping ability, sprint speed, and thigh muscle thickness. Men gained more in strength and vertical jump, while women gained more in short sprint performance.

When people squat with controlled speed and moderate weight, their muscles stretch and contract forcefully, which activates nerves that tell the brain to recruit more muscle fibers. Men develop stronger muscle contractions and faster force production, making them jump higher and lift more weight. Women develop more efficient muscle coordination during rapid movements, making them sprint faster.
What the research says
1 studyBoth guys and girls got stronger, jumped higher, ran faster, and grew thicker thigh muscles after doing the same speed-based squat training. But guys got noticeably stronger and jumped higher, while girls got faster at sprinting short distances.
