Changes of physical capabilities of muscular strength, power and flexibility in a karate competition




Performance analysis of sport, Martial arts, Athletic performance, Athlete


Karate is an ancient martial art practiced by around 100 million people worldwide. In Brazil, it is estimated that approximately 250,000 people practice this modality. However, limited data are available outlining the physical capabilities of these athletes. The purpose was analysing changes in physical capabilities of muscular strength, power and flexibility in karate athletes during a state championship. Data were collected during a karate state championship. From a total of approximately 200 participating athletes, data were collected from male (n = 34, 19.0 ± 9.84 years, 67.6 ± 21.8 kg, 165 ± 11.2 cm, 24 .3 ± 5.99 kg/m²) and female athletes (n = 12, 16.0 ± 4.47 years, 59.1 ± 11.8 kg, 156 ± 6.35 cm, 24.1 ± 4.35 kg /m²). Measurements: body mass, height, flexibility, handgrip muscular strength and lower limb power were performed before and after competition fights by a team of trained evaluators. Data were analysed between sexes, pre and post-competition, as well by age group and number of fights performed. After the fights, there was a significant increase in muscular strength (+5.2%, p = .004), with no difference between different age groups (p = .141), sexes (p = .196), and number of fights performed (p = .072). There were no significant changes in muscle power performance (p = .124) and flexibility (p = .241) across fights or between sexes. A karate tournament in which athletes are involved in one to three fights does not seem to impair their performance in terms of muscular strength, power and flexibility, regardless of age, sex and number of fights performed.
