The Claim

In untrained collegiate women, resistance training performed to muscular failure with moderate-load or high-load protocols is associated with similar improvements in vertical jump height and chest pass velocity.

In plain English

In untrained female college athletes, lifting weights to muscle failure using either moderate or heavy loads results in the same increase in vertical jump height and chest pass speed.

See the scientific wording

In untrained collegiate women, resistance training performed to muscular failure with moderate-load or high-load protocols is associated with similar improvements in vertical jump height and chest pass velocity, suggesting that power adaptations may not be load-dependent in novice trainees.

Why this might work

When muscles are pushed to complete fatigue during lifting, they grow larger and the nervous system becomes better at activating them quickly. This allows the body to generate more force in explosive movements like jumping and throwing, regardless of whether the weights are light or heavy.

    For women new to lifting weights, whether they use lighter or heavier weights, as long as they push themselves until they can’t do another rep, they improve their jumping and throwing power just as much.
