Fifteen academy under-17 players participated. In Experiment 1, players completed an all-out RHIR protocol (10x30 m, with 30s intervals). In Experiment 2 (cross-over design), participants performed this running protocol under two conditions: (1) following RHIR 5 minutes of cooling where ice packs were applied to the quadriceps/hamstrings, (2) a control condition involving passive resting. Perceptual measures [ratings of perceived exertion (RPE), pain and recovery], thigh temperature and kick-derived video three-dimensional kinematics (lower limb) and performance (ball speed and two-dimensional placement indices) were collected at baseline, post-exercise and intervention. In Experiment 1, RHIR led to small-to-large impairments (p < 0.03;d = -0.42--1.83) across perceptual, kinematic and performance measures. In experiment 2, RPE (p < 0.01; Kendall's W = 0.30) and mean radial error (p = 0.057; eta(2) = 0.234) increased only post-control. Significant small declines in ball speed were also observed post-control (p < 0.05; d = 0.35). Post-intervention foot centre-of-mass velocity was moderately faster in the cooling compared to control condition (p = 0.04; d = 0.60). In youth soccer players, a short cooling period was beneficial in counteracting declines in kicking performance, in particular ball placement, following intense running activity in the heat. | Notes: | Vieira, LPH (corresponding author), Sao Paulo State Univ Unesp, Fac Sci, Grad Program Movement Sci, Phys Educ Dept,Human Movement Res Lab MOVI LAB, Av Eng Luis Edmundo Carrijo Coube,2085-Nucleo Res, BR-17033360 Bauru, SP, Brazil. luiz.palucci@unesp.br |
