Summary

This pilot trial tests whether adding a four-week reverse nordic exercise program to regular training can improve countermovement jump performance in youth soccer players aged 16 to 18. Participants are randomly assigned to either the exercise group or a control group that continues usual training. Jump height and flight time are measured before and after the program to see if the exercise shows promise.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a four-week reverse nordic exercise program added to regular soccer training
What this could lead to
If it works, this could point toward a simple exercise to boost jumping ability in young athletes.
What could go wrong
This is a very small pilot trial with only 18 participants, so results may not be reliable or apply to all players. The exercise also carries a risk of knee strain.
