This study examined the relationships between VO2max, power maintenance and oxygen consumption during intense intermittent work. Female recreational soccer players were assigned to either a low aerobic power group (LOW, n = 6, mean (SD) VO2max = 34.4 (2.4) mL.kg(-1)min(-1) or to a moderate aerobic power group (MOD, n = 7, VO2max = 47.6 (3.8) mL.kg(-1).min(-1)). VO2 was measured while subjects performed 10 6-s all-out sprints (30-s passive recovery) on a Monark cycle ergometer. LOW and MOD subjects generated similar peak 6-s power (p = .58) but MOD had a smaller decrement in power (% DO) over the 10 sprints (LOW vs MOD: 18.0 (7.6) vs 8.8 (3.7) % DO, p = .02). The MOD group also consumed significantly more oxygen than LOW in 9 of the 10 sprint-recovery cycles (p < .05). Significant relationships were seen between VO2max and the aerobic response to the sprint-recovery series (r = .78, p =.002) as well as between VO2max and % DO (r = -.65, p = .02), while a non-significant relationship was seen between the oxygen consumed during the sprint-recovery cycles and % DO (r = -.41, p = .16). Thus, VO2max appears to be related to both an increased aerobic contribution to sprint-recovery bouts and the enhanced ability of the MOD group to resist fatigue during intense intermittent exercise.
本研究调查了最大摄氧量（VO2max）、功率维持与高强度间歇运动期间耗氧量之间的关系。将女性业余足球运动员分为低有氧功率组（LOW，n = 6，平均（标准差）VO2max = 34.4（2.4）mL·kg⁻¹·min⁻¹）或中等有氧功率组（MOD，n = 7，VO2max = 47.6（3.8）mL·kg⁻¹·min⁻¹）。在受试者于Monark自行车测力计上进行10次6秒全力冲刺（30秒被动恢复）时测量VO2。LOW组和MOD组产生的6秒峰值功率相似（p = 0.58），但在10次冲刺中MOD组的功率下降百分比（%DO）较小（LOW组与MOD组：18.0（7.6）对8.8（3.7）%DO，p = 0.02）。在10个冲刺 - 恢复周期中的9个周期里，MOD组的耗氧量也显著高于LOW组（p < 0.05）。VO2max与冲刺 - 恢复系列的有氧反应之间存在显著关系（r = 0.78，p = 0.002），VO2max与%DO之间也存在显著关系（r = -0.65，p = 0.02），而冲刺 - 恢复周期中的耗氧量与%DO之间的关系不显著（r = -0.41，p = 0.16）。因此，VO2max似乎既与冲刺 - 恢复回合中增加的有氧贡献有关，也与MOD组在高强度间歇运动期间抵抗疲劳的能力增强有关。
