Effect of different stretching methods on static and dynamic balance and physical fitness in male university students

The purpose of this study was to compare the effect of static, dynamic and proprioceptive neuromuscular facilitation (PNF) stretching methods on balance ability and the five basic components of physical fitness in male university students. Using a randomized crossover study design, 11 male college students took part in each of 4 stretching sessions. All stretching was performed at 2-day interval to avoid contamination of the results. As the result of this study, static and dynamic balance(p<.063) as well as physical fitness including muscle endurance(p<.882), power(p<.300) and agility(p<.151) were not statistically significant among various stretching methods. However the range of motion (ROM) at left and right hip flexion(p<.040, p<.021), core muscle strength(p<.045) and flexibility(p<.037) of the lower limb was significantly higher in PNF trial compared to the non-stretching trial. Our findings suggested importance evidence that the performing PNF stretching before training or competition might help prevent injury and improve muscle strength.
