TL;DR: The effects of foam rolling on performance and recovery are rather minor and partly negligible, but can be relevant in some cases (e.g., to increase sprint performance and flexibility or to reduce muscle pain sensation).

TL;DR: The effects of massage on performance recovery are rather small and partly unclear, but can be relevant under appropriate circumstances (short-term recovery after intensive mixed training), but it remains questionable if the limited effects justify the widespread use of massage as a recovery intervention in competitive athletes.

TL;DR: In this paper, the authors investigated changes of different markers for routine assessment of fatigue and recovery in response to high-intensity interval training (HIIT) and found significant changes in measures of neuromuscular function, CK and DOMS are related to HIIT induced fatigue and subsequent recovery.

TL;DR: Current limitations of heart rate monitoring are outlined, methodological considerations of univariate and multivariate approaches are discussed, the influence of different analytical concepts on assessing meaningful changes in heart rate responses are illustrated, and case examples for contextualizing heart rate measures using simple heuristics are provided.

TL;DR: Some TMG muscle properties are sensitive to changes in muscle force, and different lower-limb strength training protocols lead to changesIn neuromuscular function of RF, those protocols involving high and eccentric load and a high total time under tension may induce higher changes in T MG muscle properties.
