IMPACTS OF THE PNF TECHNIQUE ON FLEXIBILITY AND STRENGTH IN MARTIAL ARTS ATHLETES
ABSTRACT Introduction: Joint flexibility and muscle strength play a vital role in the training process of martial arts athletes. The proprioceptive neuromuscular facilitation (PNF) technique encourages the neural receptors, through the application of manual resistances, in the gain of functional range of motion and stability to its patients. It is believed that this technique can be adapted to the sports environment. Objective: Evaluate the impact of stretching using the PNF technique on martial arts athletes’ flexibility and muscle strength. Methods: Through a controlled experiment, 100 martial arts athletes, without significant differences, were selected as experimental subjects, and randomly divided into two groups for a 4-week experiment. The experimental group added a protocol with PNF stretching exercises in the training, while the control group performed the usual training without interventions. Indicators of flexibility, functional activities, and strength were measured before and after the intervention, compared, and statistically analyzed. Results: Joint flexibility with the shoulder rotation test evolved from 21.88±5.71 to 19.22±5.94, and the left and right division was from 16.90±5.36 to 10.57±3.75; as for muscle strength, the flexor peak moment elevated from 210.36±51.18 to 251.37± 45.72, and flexor power had a gain from 111.76±30.63 to 135.20±2,.42. The extensor peak moment also showed expressive evolutions from 179.47±43.96 to 221.52±33.60. Conclusion: The PNF stretching exercise technique effectively optimizes martial arts athletes’ joint flexibility and muscle strength. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
期刊介绍:
The Revista Brasileira de Medicina do Esporte (RBME in its Portuguese form) is an official organ of the Sociedade Brasileira de Medicina do Exercício e do Esporte (SBME) Brazilian Society of Exercise Medicine and Sports) and represents the main promotion resource of the scientific production in the Exercise Sciences and Sports Medicine (SBME) fields in our country. The RBME was launched in 1995 with trimester periodicity and became regularly bi-monthly published with no interruptions from 1999.
RBME is an inter-and multidisciplinary, peer reviewed, Open Access journal which accepts contributions from the national and international scientific community. RBME publishes original articles of high scientific relevance in Exercise and Sports Medicine, review articles, and systematic reviews.
RBME preferably publishes original articles of international interest, not only of regional significance. Its goal is to disseminate the scientific production in the areas of exercise and sports medicine through the publication of original research results and other documents that contribute to the scientific and applied knowlewdge of physical activity, exercise and sports, within the framework of biological sciences and medicina.
Its title abbreviation is Rev Bras Med Esporte, which should be used in references, footnotes and reference subtitles.
