Modelling the relationships between EEG signals, movement kinematics and outcome in soccer kicking

Recovery of kicking kinematics and performance following intermittent high-intensity running bouts in young soccer players: can a local cooling intervention help?

“…In addition, mean radial error substantially increased following the running protocol potentially performance. Recent related research has notably shown that greater ankle inversion is associated to higher mean radial error in kick attempts from entrance of penalty area (Palucci Vieira et al, 2022a). Ball speed verified in the present experiment was within the range (22–32 m/s) of age-matched players (Nunome et al, 2006; Vieira et al, 2018) while the mean radial error was slightly greater than in penalty trials or 15-m kicks (0.90–1.50 m; (Russell et al, 2011; Vieira et al, 2018)).…”

“…It is necessary to highlight a discrepant behaviour of kicking velocity and ball placement responses to the exercise whilst recovery intervention effect was similar for both aspects. In fact central and peripheral signalling paths/measures responsible for kick accuracy and velocity are not the same (Palucci Vieira et al, 2022a), which a priori help justify differences. However, exercise-related fatigue affects to a similar extent the functioning of brain regions/waves determinants for ball speed (frontal theta) and placement (occipital alpha) (Baumeister et al, 2012) meaning that the problem could be more at limb level.…”

“…Our findings are in accordance with those of Rampinini et al (2008) who verified impaired short passing performance in youth players following RHIR that attempted to reproduce most demanding phase of matches (10 × 40 m with one change-of-direction). Importantly, exercising with RHIR in addition to a heat condition are recognised to cause central neurotransmission deficits and a drop in muscle activity (Goodall et al, 2015; Meeusen et al, 2006; Perrey et al, 2010), both determinant aspects to proficiency in targeting the ball when kicking (Palucci Vieira et al, 2022a; Palucci Vieira et al, 2021b). To summarize, intense and consecutive running bouts (e.g.…”

“…Custom-built routines were written to obtain linear velocities (non-preferred hip, CM foot and CM foot to knee relative), angular (i) joint displacement (ankle plantarflexion/dorsiflexion and eversion/inversion at impact) (ii) range-of-motion (hip and knee flexion/extension) and (ii) peak knee extension velocity. These were computed using local reference frames of joints and segments as described elsewhere (Palucci Vieira et al, 2021a; Palucci Vieira et al, 2022a).…”
