Hypothesis
Does combining proprioceptive neuromuscular facilitation (PNF) with neuromuscular electrical stimulation (NMES) improve hamstring flexibility and vertical jump capacity in young basketball players?
Conclusion
Both PNF and PNF + NMES are effective in increasing hamstring flexibility in young basketball players without negatively affecting vertical jump performance.
Supporting Evidence
- Both PNF and PNF + NMES groups showed significant improvements in hamstring flexibility.
- Vertical jump capacity did not significantly change after either intervention.
- Participants were randomly assigned to ensure unbiased results.
Takeaway
This study shows that stretching can help young basketball players become more flexible without making them jump worse.
Methodology
The study was a randomized controlled trial comparing two groups: one performing PNF stretching and the other PNF + NMES, measuring hamstring flexibility and jump capacity before and after the intervention.
Potential Biases
Potential bias due to the lack of blinding for participants and researchers conducting the interventions.
Limitations
The sit-and-reach test was not performed using a standard box, which may affect comparability with other studies.
Participant Demographics
45 young male basketball players aged 11 to 18 years.
