The effect of a 22.5 week training program on the fuel-hormone response to prolonged (1 h) high intensity (85% maximal aerobic power, MAP) of six male subjects was studied. The training program consisted of pedalling 1 h per day, four days a week, a bicycle ergometer at 80% of their MAP. It resulted in a 14.3% increase in Vo2 max (P less than 0.01). Training did not significantly alter the RQ neither the blood glucose and lipid values measured at the end of a 1 h exercise requiring 85% of Vo2 max. At the end of the exercise blood level of norepinephrine was unchanged; in contrast, that of epinephrine was significantly (35%; P less than 0.01) reduced at the end of training. These results lead to the conclusion that during high intensity submaximal exercise there is no consistent relationship between the epinephrine blood level and mobilization or metabolic utilization of energy substrates in trained subjects.
研究了一项为期22.5周的训练计划对6名男性受试者在长时间(1小时)高强度(85%最大有氧功率,MAP)运动中燃料-激素反应的影响。训练计划包括每周四天,每天骑行1小时自行车测力计,强度为其MAP的80%。这使得最大摄氧量(Vo2 max)增加了14.3%(P<0.01)。训练并未显著改变呼吸商(RQ),也未改变在需要85%Vo2 max的1小时运动结束时测得的血糖和血脂值。运动结束时,去甲肾上腺素的血液水平未发生变化;相反,训练结束时肾上腺素的血液水平显著降低(35%;P<0.01)。这些结果得出结论,在训练有素的受试者进行高强度次最大运动期间,肾上腺素血液水平与能量底物的动员或代谢利用之间不存在一致的关系。
