Strong Support

For young male rugby players who lift weights, doing high-rep, lighter weight workouts seems to slow them down and make them less agile for a day or two more than doing low-rep, heavy weight workouts.

The Acute Effect of Increasing Resistance Training Workload Volume on Muscle Damage Markers and Performance in Heavy Resistance-Trained Youth Athletes

Cross-Sectional Study
Human

The study found that when young rugby players switched to a higher-rep, lower-weight workout, they were slower and less agile the next day compared to when they did heavy strength training, which supports the claim.

Similar Assertions

In young male rugby players who lift weights, doing high-rep, lighter weight workouts leads to worse sprinting and agility performance for up to two days compared to low-rep, heavy weight workouts.

For young male rugby players who lift weights, doing more reps to build muscle might slightly hurt their jumping ability compared to training for pure strength — but the measurement wasn't perfect, so we're not totally sure.

Young male rugby players who do high-volume muscle-building workouts might see a small drop in their jump performance compared to those doing heavy strength training — but the results aren't super clear because different equipment was used.

Even though the players got stronger from doing leg presses, they didn’t run any faster after five weeks — meaning just getting stronger on a machine doesn’t automatically make you sprint better.

Lifting more weights each week makes you stronger, but the extra strength you gain from each additional set gets smaller faster than the muscle gains do.
