这项研究的目的是评估在跑步和/或自行车训练活动中使用一项测量心肺变量的单一测试来建立训练指南的可行性。六名铁人三项运动员(两名女性和四名男性)，六名跑步运动员(两名女性和四名男性)和六名男性自行车运动员，都经过5.5年的认真训练，仍然参加比赛，他们在跑步机和自行车测功器上进行了测试。心肺变量[例如心率(HR)、每分钟通气量、二氧化碳排出量((V)与点二氧化碳之比(V)]相对于固定百分比的最大摄氧量((V)/点O-2max，从50%到100%)进行计算。所有受试者在跑步机上的O-2max上的(V)值显著高于功率计[均值(扫描电子显微镜)4.7(0.8)和L 4.4(0.9)](P<；0.05)。分钟(-1)]，测试之间的差异平均为10.5%的跑步者，6.1%的铁人和2.8%的自行车运动员。采用3x2x6设计(分组x测试x强度)的三向方差分析表明，所有因素在测试之间对所有变量都产生了非常显著的F比率(P<；0.05)，即使心率的差异只有4个节拍。分钟(-1)。当HR与(V)在点O-2max上的固定百分比相对应时，在测试之间发现了高度的相关性。这些结果表明，对于铁人三项运动员、自行车运动员和跑步运动员，无论是在跑步机上还是在自行车功率机测试中获得的心率与(V)/O-2max的百分比之间的关系，可以独立于O-2max上的绝对(V)来获得可用于监测他们的跑步和/或自行车训练的参考HR值。
The objective of this study was to evaluate the viability of using a single test in which cardiorespiratory variables are measured, to establish training guidelines in running and/or cycling training activities. Six triathletes (two females and four males), six runners (two females and four males) and six males cyclists, all with 5.5 years of serious training and still involved in racing, were tested on a treadmill and cycle ergometer. Cardiorespiratory variables [e.g., heart rate (HR), minute ventilation, carbon dioxide output ((V) over dot CO2)] were calculated relative to fixed percentages of maximal oxygen uptake ((V) over dot O-2max, from 50 to 100%). The entire group of subjects had significantly (P < 0.05) higher values of (V) over dot O-2max on the treadmill compared with the cycle ergometer [mean (SEM) 4.7 (0.8) and 4.4 (0.9) l . min(-1), respectively], and differences between tests averaged 10.5% for runners, 6.1% for triathletes and 2.8% for cyclists. A three-way analysis of variance using a 3 x 2 x 6 design (groups x tests x intensities) demonstrated that all factors yielded highly significant F-ratios (P < 0.05) for all variables between tests, even though differences in HR were only 4 beats . min(-1). When HR was plotted against a fixed percentage of (V) over dot O-2max, a high correlation was found between tests. These results demonstrate that for triathletes, cyclists and runners, the relationship between HR and percentage of (V) over dot O-2max, obtained in either a treadmill or a cycle ergometer test, may be used independently of absolute (V) over dot O-2max to obtain reference HR values that can be used to monitor their running and/or cycling training bouts.
