The physiological response to a given training load is commonly called the dose–response relationship and is considered a fundamental component of training. 1 It has been suggested that a valid measure of training load should show a strong dose–response relationship with a particular training

/strength have been postulated: (1) a dose–response relationship where gradual increases in weekly RT volume lead to a greater increase muscle mass and strength, 6 (2) an inverted-U relationship whereby increasing weekly RT volume beyond a certain threshold negatively impacts skeletal muscle accretion, 12 and

individualization approach to external load monitoring enhances the dose–response determination, and at this stage, the findings are equivocal. 15 – 17 The within-player association between high-speed running (HSR) and very high-speed running (VHSR) versus next day wellness ratings was small to moderate, and not

The aim of this study was to examine the dose-response relationship between walking activity and physical function (PF) in community-dwelling older adults. Physical activity (PA, pedometry) and PF (self-report [SF-36] and 6-minute walk test [6MWT]) were assessed in 836 individuals. Accumulated PA was categorized into four groups (1 = ≤ 2,500; 2 = 2,501–5,000; 3 = 5,001–7,500; and 4 = ≥ 7,501 steps/day). Across individual groups 1–4, SF-36 scores increased from 66.9 ± 25.0% to 73.5 ± 23.2% to 78.8 ± 19.7% to 81.3 ± 20.6%, and 6MWT increased from 941.7 ± 265.4 ft to 1,154.1 ± 248.2 ft to 1,260.1 ± 226.3 ft to 1,294.0 ± 257.9 ft. Both SF-36 and 6MWT scores were statistically different across all groups, apart from groups 3 and 4. PA and ranks of groups were highly significant predictors (p < .0001) for both SF-36 and 6MWT. There was a positive dose-response relationship evident for both SF-36 and 6MWT with increasing levels of PA. Low levels of PA appear to be an important indicator of poor functionality in older adults.

However, few studies have attempted to examine this dose–response relationship and have not considered a comprehensive range of internal and external TL in relation to the CMJ. 3 , 18 , 19 If this relationship is present, then practitioners can be more confident that a change in TL
