MEN vs WOMEN | Sex Differences in Training | Science Explained (12 Studies)

Summary by Krater

This video examines scientific research on muscle hypertrophy in men and women, concluding that while men generally possess greater absolute muscle mass and strength, men and women have very similar relative growth potential, recovery abilities, and fatigability when adjusted for body composition.

From the video

Answers: Do men and women have different muscle growth potential and training responses?

• Muscle hypertrophy in men versus women
• Relative growth potential and muscle mass
• Fatiguability and blood flow in training
• Upper and lower body strength differences

What it concludes

• Men and women have essentially the exact same relative muscle growth potential.
• Women can build an appreciable amount of muscle, likely falling between 50 to 100 percent of the hypertrophic potential of men.
• The 97 percent difference in strength between men and women is attributed to differences in muscle mass and nothing else.
• Women have better blood flow and muscle perfusion, leading to lower fatiguability and better recovery from high-repetition work.
• Women have about 50 percent of the strength of men in the upper body and 66 percent in the lower body, explaining why they tend to enjoy training legs more.
