- Abstract
Objective: Muscle stretching is applied with the purpose of increasing range of motion. Different techniques are used for this purpose, including proprioceptive neuromuscular facilitation (PNF) and dynamic stretching, but it is still unclear which one is more effective. The objective of this research was to estimate the efficacy of the hold-relax technique compared to dynamic stretching on hamstring flexibility in healthy young adults. Methodology: Randomized controlled trial with blinding, consisting of two intervention arms. The study included a total of 32 young adult volunteers aged 18 to 30 years, who were randomized into two intervention groups: PNF (n = 16) and dynamic stretching (n = 16). Knee joint flexibility was assessed using the popliteal angle measured with a goniometer. Results: The mean age, weight, height, and body mass index were found to be equivalent, indicating comparable groups. No significant differences were found between the stretching groups in the adjusted means, with a mean difference of -2.09 (95 % CI -7.05 to 2.87). Conclusions: Both dynamic stretching and PNF demonstrated an increase in knee range of motion, with both stretching techniques showing differences from the baseline. No significant differences were found between the stretching groups.
