Hand Cooling and Recovery of Jump Performance and Knee Kinetics After Fatigue

Description

This dataset contains the raw and/or processed data collected from a randomized, counterbalanced crossover study investigating the effects of hand cooling on fatigue recovery and lower-limb neuromuscular and biomechanical responses. The dataset includes participant characteristics, countermovement jump performance, single-leg landing biomechanics, tensiomyography parameters, blood lactate concentration, and ratings of perceived exertion across the control, placebo, and hand-cooling conditions.

Steps to reproduce

Participants should first complete a familiarization session and baseline measurements before participating in three experimental conditions: control (CON), placebo (PLA), and hand cooling (HC). The three conditions should be performed in a randomized, counterbalanced crossover design, with a 7-day washout period between sessions. Following baseline testing, participants should perform a standardized lower-limb fatigue protocol consisting of repeated forward lunges until the predefined fatigue criterion is reached. Immediately after the fatigue protocol, participants should undergo the assigned 4-min recovery intervention. In the CON condition, the hands should be exposed to temperature-matched water; in the HC condition, the hands should be immersed in 10°C water; and in the PLA condition, the placebo procedure should be applied according to the original study protocol. Before and immediately after the fatigue protocol and recovery intervention, participants should complete the same outcome assessments in a standardized order. Countermovement jump (CMJ) performance should be assessed, followed by single-leg landing (SLL) testing to obtain peak knee joint moment, knee joint stiffness, and peak knee flexion angle. Tensiomyography (TMG) should then be used to assess the rectus femoris, including maximal radial displacement (Dm) and contraction time (Tc). Blood lactate (BLa) concentration and rating of perceived exertion (RPE) should also be recorded at the predefined time points. All experimental procedures, measurement conditions, equipment settings, fatigue criteria, and data-processing procedures should follow those described in the original study manuscript to ensure consistency and reproducibility.
