Efeitos de carboidratos e eletrólitos sobre a termorregulação e a potência anaeróbia medida após um exercício prolongado no calor

摘要: Most of the energy needed for muscle contraction during Wingate anaerobic test is derived from adenosine triphosphate, creatine phosphate and glucose breakdown. Exogenous carbohydrates contribute to maintenance blood that could lead improvement performance following a prolonged sub-maximal exercise (PE). The purpose present study was compare power output men in performed immediately after 90 min cycling at 60% maximal workload, with without ingestion electrolytes (CHO), as well physiological responses PE. Seven (21.4 ± 4.2 yrs; 65.46 10.45 kg; 9.4 1.8% fat 60.38 4.76 mLO2.kg-1.min-1) volunteered study. They received adequate amounts distilled water capsules containing either (CHO) or placebo (PLA) every 15 min, while exercising on an environmental chamber 28 oC temperature 79% air relative humidity, double-blind protocol. Rectal temperatures heart rates were monitored continuously. Blood lactate also measured. Sweat estimated pre post-exercise body weight differences, taking into account intake urine excretion. As expected, significantly higher (p ≤ 0.05) CHO (116 12mg/dL) than PLA (81 7mg/dL). Relative (12.63 1.27 W·Kg-1) ( 12.64 1.30 total work (18.57 2.86 KJ) (20.36 6.01 not different. Thermal regulation unaffected. did affect any variables under investigation
