The main aim of the present study was to compare measured oxygen consumption (Measured-VO2) in a simulated futsal game (S-Game) with the estimated oxygen consumption (Estimated-VO2) through a regression equation between heart rate (HR) and oxygen consumption (VO2) (HR-VO2) in treadmill running, and a secondary aim was to calculate the total energy expenditure (EE) in S-Game. Ten professional players (22.20 ± 3.22 years) were evaluated. HR-VO2 was determined individually in the continuous test on the treadmill (ContTest). The Measured-VO2 in S-Game was compared with the Estimated-VO2 in the ContTest. Alactic and lactic pathways were estimated by VO2. The Estimated-VO2 presented no statistically significant difference with the Measured-VO2, paired test-t (p = 0.38). However, the correlation between Estimated and Measured VO2 was very weak (r = -0.05) and it presented poor agreement (CCC = -0.04). In addition, Bland Altman plot presented bias of -2.8 mL·kg-1·min-1 and individual difference as large as 19 mL·kg-1·min-1. The HR-VO2 determined by the ContTest was not a good individual predictor of VO2. The high intensity and intermittent nature of the futsal game possibly caused dissociation in the HR-VO2 relationship. Continuous test on a treadmill is not recommended for estimating VO2 and calculating individual EE in futsal game. This is recommended only for the group mean. The total EE in S-Game was 13.10 ± 1.25 kcal·min-1 (10.81 ± 1.57 METs). The contribution from the metabolic pathways was: aerobic (93%), alactic (5%), and lactic (2%).

五人制足球心率、耗氧量与能量消耗的关系

本研究的主要目的是通过心率 (HR) 和氧气之间的回归方程比较模拟五人制足球比赛 (S-Game) 中测得的耗氧量 (Measured-VO2) 与估计的耗氧量 (Estimated-VO2)。跑步机运行中的消耗 (VO2) (HR-VO2),次要目标是计算 S-Game 中的总能量消耗 (EE)。评估了十名职业球员(22.20±3.22 岁)。HR-VO2 是在跑步机上的连续测试 (ContTest) 中单独确定的。将 S-Game 中的测量 VO2 与 ContTest 中的估计 VO2 进行比较。无乳酸和乳酸途径由 VO2 估计。Estimated-VO2 与 Measured-VO2、配对测试 t (p = 0.38) 没有统计学上的显着差异。然而,估计和测量的 VO2 之间的相关性非常弱(r = -0。05) 并且它的一致性很差 (CCC = -0.04)。此外,Bland Altman图存在-2.8 mL·kg-1·min-1的偏倚和高达19 mL·kg-1·min-1的个体差异。ContTest 确定的 HR-VO2 不是 VO2 的良好个体预测指标。五人制足球比赛的高强度和间歇性可能导致 HR-VO2 关系的分离。不建议在跑步机上进行连续测试来估计 VO2 和计算五人制足球比赛中的个人 EE。这仅建议用于组均值。S-Game 中的总 EE 为 13.10 ± 1.25 kcal·min-1 (10.81 ± 1.57 METs)。代谢途径的贡献是:有氧 (93%)、无乳酸 (5%) 和乳酸 (2%)。8 mL·kg-1·min-1,个体差异高达19 mL·kg-1·min-1。ContTest 确定的 HR-VO2 不是 VO2 的良好个体预测指标。五人制足球比赛的高强度和间歇性可能导致 HR-VO2 关系的分离。不建议在跑步机上进行连续测试来估计 VO2 和计算五人制足球比赛中的个人 EE。这仅建议用于组均值。S-Game 中的总 EE 为 13.10 ± 1.25 kcal·min-1 (10.81 ± 1.57 METs)。代谢途径的贡献是:有氧 (93%)、无乳酸 (5%) 和乳酸 (2%)。8 mL·kg-1·min-1,个体差异高达19 mL·kg-1·min-1。ContTest 确定的 HR-VO2 不是 VO2 的良好个体预测指标。五人制足球比赛的高强度和间歇性可能导致 HR-VO2 关系的分离。不建议在跑步机上进行连续测试来估计 VO2 和计算五人制足球比赛中的个人 EE。这仅建议用于组均值。S-Game 中的总 EE 为 13.10 ± 1.25 kcal·min-1 (10.81 ± 1.57 METs)。代谢途径的贡献是:有氧 (93%)、无乳酸 (5%) 和乳酸 (2%)。不建议在跑步机上进行连续测试来估计 VO2 和计算五人制足球比赛中的个人 EE。这仅建议用于组均值。S-Game 中的总 EE 为 13.10 ± 1.25 kcal·min-1 (10.81 ± 1.57 METs)。代谢途径的贡献是:有氧 (93%)、无乳酸 (5%) 和乳酸 (2%)。不建议在跑步机上进行连续测试来估计 VO2 和计算五人制足球比赛中的个人 EE。这仅建议用于组均值。S-Game 中的总 EE 为 13.10 ± 1.25 kcal·min-1 (10.81 ± 1.57 METs)。代谢途径的贡献是:有氧 (93%)、无乳酸 (5%) 和乳酸 (2%)。
