To evaluate the metabolic relevance of type of locomotion in anaerobic testing by analyzing and comparing the metabolic profile of the Bosco Continuous Jumping Test (CJ30) with the corresponding profile of the Wingate Anaerobic Test (WAnT).
A total of 11 well-trained, male team-sport athletes (age = 23.7 [2.2] y, height = 184.1 [2.8] cm, weight = 82.4 [6.4] kg) completed a CJ30 and WAnT each. During the WAnT, power data and revolutions per minute were recorded, and during the CJ30, jump height and jumping frequency were recorded. In addition, oxygen uptake and blood lactate concentration were assessed, and metabolic profiles were determined via the PCr-LA-O2 method.
In the CJ30, metabolic energy was lower (109.3 [18.0] vs 143.0 [13.1] kJ, P < .001, d = -2.302), while peak power (24.8 [4.4] vs 11.8 [0.5] W·kg-1, P < .001, d = 3.59) and mean power (20.8 [3.6] vs 9.1 [0.5] W·kg-1, P < .001, d = 4.14) were higher than in the WAnT. The metabolic profiles of the CJ30 (aerobic energy = 20.00% [4.7%], anaerobic alactic energy [WPCr] = 45.6% [4.5%], anaerobic lactic energy = 34.4% [5.2%]) and the WAnT (aerobic energy = 16.0% [3.0%], anaerobic alactic WPCr = 34.5% [5.0%], anaerobic lactic energy = 49.5% [3.3%]) are highly anaerobic. Absolute energy contribution for the CJ30 and WAnT was equal in WPCr (49.9 [11.1] vs 50.2 [11.2] kJ), but anaerobic lactic energy (37.7 [7.7] vs 69.9 [5.3] kJ) and aerobic energy (20.6 [5.7] vs 23.0 [4.0] kJ) were higher in the WAnT. Mechanical efficiency was substantially higher in the CJ30 (37.9% [4.5%] vs 15.6% [1.0%], P < .001, d = 6.86), while the fatigue index was lower (18.5% [3.8%] vs 23.2% [3.1%], P < .001, d = -1.38) than in the WAnT.
Although the anaerobic share in both tests is similar and predominant, the CJ30 primarily taxes the WPCr system, while the WAnT more strongly relies on the glycolytic pathway. Thus, the 2 tests should not be used interchangeably, and the type of locomotion seems crucial when choosing an anaerobic test for a specific sport.
通过分析和比较 Bosco 连续跳跃测试(CJ30)与相应的无氧测试(WAnT)的代谢谱,评估无氧测试中运动类型的代谢相关性。
共有 11 名训练有素的男性团队运动运动员(年龄=23.7[2.2]岁,身高=184.1[2.8]厘米,体重=82.4[6.4]千克)分别完成了 CJ30 和 WAnT。在 WAnT 中,记录功率数据和每分钟转数,在 CJ30 中,记录跳跃高度和跳跃频率。此外,评估了氧摄取量和血乳酸浓度,并通过 PCr-LA-O2 方法确定代谢谱。
在 CJ30 中,代谢能量较低(109.3[18.0]比 143.0[13.1]kJ,P<0.001,d=-2.302),而峰值功率(24.8[4.4]比 11.8[0.5]W·kg-1,P<0.001,d=3.59)和平均功率(20.8[3.6]比 9.1[0.5]W·kg-1,P<0.001,d=4.14)高于 WAnT。CJ30(有氧能量=20.00%[4.7%],无氧无乳酸 WPCr=45.6%[4.5%],无氧乳酸能量=34.4%[5.2%])和 WAnT(有氧能量=16.0%[3.0%],无氧无乳酸 WPCr=34.5%[5.0%],无氧乳酸能量=49.5%[3.3%])的代谢谱均为高度无氧。CJ30 和 WAnT 的绝对能量贡献在 WPCr 中相等(49.9[11.1]比 50.2[11.2]kJ),但无氧乳酸能量(37.7[7.7]比 69.9[5.3]kJ)和有氧能量(20.6[5.7]比 23.0[4.0]kJ)在 WAnT 中更高。CJ30 的机械效率显著更高(37.9%[4.5%]比 15.6%[1.0%],P<0.001,d=6.86),而疲劳指数较低(18.5%[3.8%]比 23.2%[3.1%],P<0.001,d=-1.38)。
尽管两种测试中的无氧比例相似且占主导地位,但 CJ30 主要依赖 WPCr 系统,而 WAnT 更依赖糖酵解途径。因此,两种测试不应互换使用,而且当为特定运动选择无氧测试时,运动类型似乎至关重要。
