Abstract

The primary purpose of the study was to compare maximal accumulated oxygen deficit (MAOD) in resistance-trained (RT), endurance-trained (ET), and untrained men (UT). A secondary purpose was to determine the influence of leg muscle mass (MM) on MAOD by examining the relationship between MM and MAOD and by comparing MAOD expressed relative to MM between the groups. MAOD was determined during 2-4 min of constant-load fatiguing cycling. MM, estimated via anthropometric measurements, was higher (p < .05) for RT (mean +/- SE; 25.5 +/- 3.4 kg) compared to ET (20.3 +/- 3.5) and UT (21.6 +/- 3.4). MAOD in liters O2eq was larger in RT (4.75 +/- 0.3) compared to UT (3.07 +/- 0.3) and ET (3.75 +/- 0.3). A significant positive correlation was observed between MAOD (LO2eq) and MM (kg) for RT only (RT, r = .85; ET, r = .55; UT, r = .20). Based on the correlational and mean MM data, the higher MAOD (LO2eq) in RT relative to ET and UT is predominantly the result of their larger leg muscle mass.

摘要

该研究的主要目的是比较抗阻训练（RT）男性、耐力训练（ET）男性和未训练男性（UT）的最大累积氧亏（MAOD）。次要目的是通过检查腿部肌肉质量（MM）与MAOD之间的关系，以及比较各组间相对于MM的MAOD，来确定腿部肌肉质量对MAOD的影响。MAOD是在2 - 4分钟的恒定负荷疲劳骑行中测定的。通过人体测量估算的MM，RT组（平均值±标准误；25.5±3.4 kg）高于ET组（20.3±3.5）和UT组（21.6±3.4）（p <.05）。以升O2eq为单位的MAOD，RT组（4.75±0.3）大于UT组（3.07±0.3）和ET组（3.75±0.3）。仅在RT组中观察到MAOD（升O2eq）与MM（千克）之间存在显著正相关（RT组，r =.85；ET组，r =.55；UT组，r =.20）。基于相关性和平均MM数据，RT组相对于ET组和UT组更高的MAOD（升O2eq）主要是由于其更大的腿部肌肉质量。
