Purpose: This study was conducted in order to analyze the effect of proprioceptive neuromuscular facilitation lower extremity pattern on muscular strength and flexibility in an aquatic environment.
Methods: Ten members of the experimental group and 10 members of the control group were randomly selected from 20 college students who are in their 20s. Bilateral symmetry pattern among proprioceptive neuromuscular facilitation lower extremity patterns was applied in an aquatic environment in the experimental group three times per week for a period of six weeks, and a set consisted of 10 times, which was repeated 10 times. On the other hand, subjects in the control group did not receive any treatment while maintaining daily life. Muscular strength was measured using a dynamometer and electromyogram system for maximum voluntary isometric contraction of hip flexor, hip extensor, knee flexor, and knee extensor. Cervical flexibility was measured using cervical range of motion instrument for cervical flexion, rotation, and lateral flexion. Lumbar flexibility was measured using back range of motion instrument II for lumbar flexion.
Results: For the experimental group, significance was observed for hip flexor, extensor, knee flexor, extensor, cervical flexion, rotation, lateral flexion, and lumbar flexion. For the control group, no significance was observed for any other variables except for cervical flexion. As a result of observation of difference between the two groups, relatively high significance was observed in the experimental group, compared with the control group.
Conclusion: In conclusion, proprioceptive neuromuscular facilitation lower extremity pattern had a positive effect on muscular strength and flexibility in an aquatic environment.
