The Effect of Different Intensity and Duration of Running on Balance in Male Football Player

摘要

The aim of study was to investigate the static and dynamic balance performance after different intensity and duration of running. Fifteen male football player (a=21.6 ± 0.9 y, h=172.4 ± 6.1 cm, w=68.4 ± 6.7 kg) participated. Conconi test on treadmill and variables of different exercises (Aerobic, Anaerobic, Mixed, Prolonged Intermittent and Super Maximal Intermittent) were measured. Then before and after each exercise participants did Y balance test (YBT), balance error scoring system (BESS), and rating of perceived exertion (RPE). Repeated measure ANOVA was used to data analysis. Results showed no significant difference in double leg position on firm surface after various exercises ( p 0.05). However, static balance on firm and foam surfaces in single leg and tandem positions decreased after all exercises ( p 0.05). Although, balance impairment was more noticeable after anaerobic, mixed and super maximal intermittent exercises ( p 0.05). Dynamic balance declined in three direction after all exercises and the most outstanding decrease occurred after anaerobic exercise in anterior direction ( p 0.05). Thus, during balance assessment, intensity and duration of exercise and balance positions should considered evaluating sport performance and clinical application .
