Abstract

Purpose: The aim of the present study was to compare performance and physiological effects, and inter-individual response variation in performance and its physiological determinants between heart rate-based (HR), race pace-based (RP), and heart rate variability-based (HRV) training prescription approaches in recreational distance runners.

Methods: Twenty-eight participants completed a 6-wk endurance training intervention after being randomly assigned to three groups: HR ( n = 9), RP ( n = 9), and HRV ( n = 10) training prescription approaches.

Results: No interaction effects between groups were observed. Main time effects were found for absolute and relative maximal oxygen consumption (V̇O 2max ), running economy (RE), speeds associated with the first (sVT1) and second ventilatory thresholds (sVT2), and 7-km time trial performance (TT) ( P < 0.001, 0.88 ≤ d ≤ 2.67). The RP group improved TT ( P < 0.05, effect size = 1.07), showing greater effectiveness in enhancing maximal aerobic speed and fat mass reduction, but did not consistently improve physiological parameters like sVT2 or RE. The HRV method increased sVT2 ( P < 0.01, effect size = 1.34) and was more successful in boosting sVT1 and V̇O 2max , although it resulted in an increase in fat mass. Training load was similar between groups ( P > 0.05), and a pyramidal training intensity distribution model was found in all groups. The lowest inter-individual response variation in TT was found in the RP group (coefficient of variation (CV) = 0.82), whereas the HRV group demonstrated a lower variation in relative V̇O 2max (CV = 0.75) and sVT2 (CV = 0.79).

Conclusions: The RP approach is an effective and useful training prescription method for optimizing performance in recreational runners, whereas the HRV method proves valuable for enhancing key physiological markers.

跑步者以比赛速度为基础与心率变异性为指导的训练处方的表现和生理影响。
目的:本研究的目的是比较休闲长跑运动员基于心率(HR)、基于比赛配速(RP)和基于心率变异性(HRV)的训练处方方法的表现和生理效果,以及表现的个体间反应差异及其生理决定因素。方法:28名参与者被随机分为三组:HR (n = 9)、RP (n = 9)和HRV (n = 10)训练处方方法,完成了为期6周的耐力训练干预。结果:各组间无交互作用。绝对和相对V (O2max)、运行经济性(RE)、与第一呼吸阈值(sVT1)和第二呼吸阈值(sVT2)相关的速度和7公里计时赛性能(TT)受时间影响最大(p < 0.001, 0.88≤d≤2.67)。RP组改善了TT (p < 0.05, ES = 1.07),在提高最大有氧速度和减少脂肪量方面表现出更大的效果,但没有持续改善生理参数,如sVT2或RE。HRV方法增加了sVT2 (p < 0.01, ES = 1.34),在提高sVT1和vo2max方面更成功,尽管它导致脂肪量增加。各组间训练负荷差异无统计学意义(p < 0.05),各组训练强度均呈金字塔型分布。RP组TT个体间反应差异最小(变异系数[CV] = 0.82),而HRV组相对V / O2max (CV = 0.75)和sVT2 (CV = 0.79)差异较小。结论:RP方法是一种有效且有用的训练处方方法,可以优化休闲跑者的表现,而HRV方法在增强关键生理指标方面具有价值。
