Malone, S, Hughes, B, Collins, K, and Akubat, I. Methods of monitoring training load and their association with changes across fitness measures in hurling players. J Strength Cond Res 34(1): 225-234, 2020-The aim of the current investigation was to assess the dose-response relationship for various methods of monitoring training load (TL) and changes in aerobic and anaerobic fitness in hurling players. Training and match load measures were collected from 30 hurling players (speed at different blood lactate [vLT, vOBLA], maximal oxygen uptake [VO2max], speed at VO2max [vVO2max], peak treadmill velocity [PTV] running economy [RE] Yo-Yo intermittent recovery test (Yo-YoIR1, Yo-YoIR2), speed at 5, 10 , 20 m, and repeated sprint ability [6 × 35 m]) before and after during a 12-week in-season period. Mean weekly training and match loads as determined by s-RPE, bTRIMP, luTRIMP, eTRIMP, iTRIMP, and gTRIMP were correlated with each other, percentage change in VO2max, vVO2max, RE, PTV, the speed at blood lactate concentrations of 2 mmol·L (vLT) and 4 mmol·L (vOBLA), and YoYoIR1, Yo-YoIR2 performance. iTRIMP showed a trivial association with s-RPE and a small to moderate association with other heart rate-based methods. Small to large changes (effect size: 0.38-1.12) were observed in aerobic and anaerobic fitness measures were observed across the 12-week period. Trivial to very large associations (r = 0.11-0.78) were observed between TL variables and changes in fitness depending on the variable analyzed. iTRIMP was shown to have large to very large associations with changes in vOBLA {r = 0.78 (95% confidence interval [CI]: 0.71-0.88)}, VO2max (r = 0.77 [95% CI: 0.68-0.82]), RE (r = 0.77 [95% CI: 0.67-0.82]), Yo-YoIR1 (r = 0.69 [95% CI: 0.51-0.72]), and RSAb (r = 0.66 [95% CI: 0.60-0.72]) with moderate associations reported between iTRIMP and other variables. All other measures of TL showed trivial to moderate associations (r = 0.11-0.66). The current investigation shows that fully individualized training load (iTRIMP) measures may potentially offer a better understanding of dose-response relationships when compared with subjective and nonindividualized measures of TL to changes in aerobic and anaerobic fitness in team sports athletes; as such, it may be suggested that practitioners should use individualized measures of TL assessment within their day-to-day practices.
马龙、休斯、柯林斯、阿库巴特。监测训练负荷的方法及其与投掷运动员体能变化的关系。《力量与条件研究杂志》34(1):225-234,2020-本研究旨在评估各种监测训练负荷(TL)的方法与投掷运动员有氧和无氧能力变化之间的剂量反应关系。在 12 周的赛季期间，对 30 名投掷运动员进行了训练和比赛负荷测量(不同血乳酸[vLT，vOBLA]速度、最大摄氧量[VO2max]、最大摄氧量[vVO2max]速度、跑步机最高速度[PTV]跑经济[RE]Yo-Yo 间歇性恢复测试(YoyoIR1、YoyoIR2)、5、10、20 m 速度和重复冲刺能力[6×35 m])，并在前后进行了测量。通过 s-RPE、bTRIMP、luTRIMP、eTRIMP、iTRIMP 和 gTRIMP 确定的平均每周训练和比赛负荷相互关联，与 VO2max、vVO2max、RE、PTV 的变化呈正相关，血乳酸浓度为 2 mmol·L(vLT)和 4 mmol·L(vOBLA)的速度，以及 YoYoIR1、Yo-YoIR2 性能。iTRIMP 与 s-RPE 呈轻微关联，与其他基于心率的方法呈小到中度关联。在 12 周的时间内，观察到有氧和无氧能力测量的小到中到大的变化(效应大小:0.38-1.12)。根据分析的变量，TL 变量与体能变化之间存在小到非常大的关联(相关系数为 0.11-0.78)。iTRIMP 与 vOBLA{相关系数为 0.78(95%置信区间[CI]:0.71-0.88)}、VO2max(r = 0.77[95%CI:0.68-0.82])、RE(r = 0.77[95%CI:0.67-0.82])、Yo-YoIR1(r = 0.69[95%CI:0.51-0.72])和 RSAb(r = 0.66[95%CI:0.60-0.72])的变化有较大到非常大的关联，而 iTRIMP 与其他变量之间的关联报告为中度(r = 0.11-0.66)。所有其他 TL 测量值均显示出轻微到中度的相关性(r = 0.11-0.66)。本研究表明，与主观和非个体化的 TL 测量相比，完全个体化的训练负荷(iTRIMP)测量可能更能更好地理解团队运动运动员有氧和无氧能力变化的剂量反应关系;因此，建议从业者在日常实践中应使用个体化的 TL 评估方法。
