ClinConnect Summary

This clinical trial is studying how two different stretching methods might help improve hamstring flexibility and jumping ability in young football players. Hamstring injuries are common in football and can keep players from training or playing for a long time. In this study, one group of players will do a special type of stretching called PNF (proprioceptive neuromuscular facilitation) combined with a treatment called NMES (neuromuscular electrical stimulation), which uses gentle electrical pulses to help muscles work better. The other group will do the same stretching but with a fake (placebo) version of the electrical stimulation to see if the real treatment makes a difference.

Young football players between the ages of 10 and 18 who train at least three times a week may be eligible to join. However, players currently doing a regular hamstring stretching program, those with recent hamstring injuries, low back pain, or recent surgeries on their back or abdomen won’t be able to participate. If you join, you’ll follow the stretching routines and receive either the real or fake electrical stimulation while your flexibility and jumping skills are measured. This study aims to find safer and more effective ways to keep young athletes active and reduce the risk of hamstring injuries.
