The Effect Of Using Ultraviolet B (uvb) Technology On The Development Of Recovery

Résumé: This study aimed to draw attention to the effective role played by ultraviolet radiation in developing aerobic capacity and developing recovery in athletes by knowing the extent of its effect on the cardiovascular system, the respiratory system and the neuromuscular system, where these rays were used as a light spectrum that athletes are exposed to during sleeping hours. In this study, we used the experimental approach on a sample of (08) eight half-long distance runners of the older class, divided into two groups (control, experimental), and tests were conducted on them (Ruffier test, Vameval test, measurements of blood oxygen transfer rate, systolic and diastolic blood pressure, resting heart rate, muscle lactate concentration), where the interval between the pre and post measurement was 19 weeks, with the obligatory use of an ultraviolet lamp in the bedroom during this period. Through the results of this study, we concluded that these rays had a significant effect on blood pressure and resting pulse, and did not affect the maximum aerobic speed and the concentration of lactic acid. Positive results can be linked to the effective role of vitamin D, which stimulates the absorption of phosphorus and magnesium, controlling blood pressure and clogged arteries, and adjusting calcium levels in the body, which reduces high blood pressure and balances the level of acidity in the body. This is evidenced by the presence of vitamin D receptors. at the lung level. Therefore, we recommend using this method to improve the functional performance of the cardiovascular system in athletes.
