The capacity to sustain a high percentage of VO2max, alsonamed aerobic endurance (5), is the last determinant of performance identified by DiPrampero et al. (15). As outlined by Pe ́ronnet and Thibault (56), the physiological basis of aerobic endurance is not clearly understood.Outstanding aerobic endurance can be associated with a combination of factors, including a high percentage of type I muscle fibers, the capacity to store large amounts of muscle and/or liver glycogen, the capacity to spare carbohydrate by using more fatty acids as energy substrate, and the capacity to efficiently dissipate heat. If the taper has been shown to affect significantly the contractile and metabolic properties of single muscle fibers (52,68), there are actually no data available to support the hypothesis of a modification in fiber distribution. It also does not seem that substrate use is affected, because the respiratory exchange ratio (RER) is most often unchanged after a taper intervention (29,51,59). However, the 13–34% taper- induced increase in muscle glycogen content observed both in men and women (52,53,62,71) could, undoubtedly, contribute to improve aerobic endurance.
的能力,以維持最大攝氧量的比例很高,也<br>命名為有氧耐力(5),是由DiPrampero等人鑑定性能的最後決定因素。(15)。正如Pe的ronnet和巴爾(56)所概述的,有氧耐力的生理基礎尚不清楚。<br>優秀有氧耐力可與多種因素的組合相關聯,包括I型肌纖維的高比例,來存儲大量的肌肉和/或肝醣原的能力,通過使用更多的脂肪酸作為能量底物的能力,以備用碳水化合物,和能力,以有效地散熱。如果錐形已被證明顯著影響收縮和單肌纖維(52,68)的代謝性質,實際上有沒有可用於支持在纖維分佈的變形例的假設數據。這也似乎不是基板的使用受到影響,因為呼吸交換率(RER)是最常見的錐形干預(29,51,59)後保持不變。然而,肌糖原含量13-34%taper-誘導增加男性和女性(52,53,62,71)均觀察可以,毫無疑問,
