Differences in hop tests before and after the match within both groups had negligible to small effect sizes (d=0.00-0.49), except for the figure of 8 and 30 seconds side hop in the injured leg of RTPf soccer players (d=0.56 and d=0.71 respectively). Differences between both groups were negligible to small (d=0.00-0.36).
Soccer players returning to performance after a lower extremity injury showed similar scores on hop tests than their non-injured teammates. More demanding sport-specific performance test and measurement of quality of movement are additionally recommended for safe return to sport decision-making.

Spectral analysis of heart rate variability (HRV) is a long-standing technique to indirectly assess neural cardiac regulation. This article specifically addressed how spectral analysis of HRV could help to understand neural cardiovascular adaptations to long-term exercise training and inform us on training status in athletes.
We reviewed literature searching for articles investigating resting cardiovascular adaptations to long-tem exercise training through spectral analysis of HRV in athletes, from amateur to world class categories, practicing different sport disciplines, focusing, in particular, on a series of work performed over time in our laboratory, which may highlight how different types of exercise training differently affect neural cardiac regulation.
Spectral analysis of HRV has been shown its capability of detecting different adaptational changes in cardiac autonomic nervous system (ANS) regulation attending physical training in athletes of different sport disciplines. Studies showed that spectral analysis of HRV provide results that are sport-dependent and differ at individual level. ANS adaptations to exercise training are presented and discussed.
Reported studies indicate that spectral analysis of HRV is an effective tool to monitor and optimize the training process and also to predict athletic achievements in competitions. Cardiac ANS adaptations are strongly dependant on the type of training being performed. The individual nature of cardiac ANS adaptations should be considered to properly interpret the observed findings.

Tennis is an open-skill sport in which the athletes have a short period of time to elaborate all the information coming from the surrounding environment and produce a motor answer based on them. The aim of this study was divided in two hypotheses (1) to assess if belonging to a certain category, athlete or non-athlete, older or younger, can affect the development of reaction time on children and (2) if a protocol based on visual training (VT) of 6 weeks could improve the motor performance on the field in young tennis players using FitLight Trainer.
In this evidence a group of young children (N=40) have been tested on light board through reaction test then some young tennis players (N=15, age 7-12 years old) were taken as reference for the second hypothesis. They were divided in two groups 7 of them were in the group Under-10 (U10) while 8 in a second group (U12). They performed a VT protocol once a week for at least 40 minutes for 6 weeks. They were tested at baseline (T0) and follow-up (T6) to evaluate the reaction time, time in specific lateral shift and precision about forehand and backhand.
The development of reaction time of the athletes is principally caused by their growth (p<0.05). see more Principal components analysis (PCA) showed significant improvements in the Under-10 category in all of the tests while in the Under-12 category not every individual showed a significant result in terms of performance.
The developing of reaction time and coordination eye-hand is mainly due to the growth of young athletes. Also, performing a 6-week VT using FitLight Trainer is possible improve the reaction time and the motor performance on the field especially in young tennis players under 10 years old.

Asymmetrical posture maintained over long training periods may affect phenotypic plasticity, resulting functional to sporting goal but negative to the locomotor system. Aim of this study was to quantitatively evaluate these long-term effects in competitive boxers.
Baropodometric analysis was used to assess 20 competitive boxers and 20 non-sportsmen in upright bipedal posture for 5 s and for 51.2 s with open (OE) and closed (CE) eyes.
The boxers’ group (BOX) showed a larger total foot load (TFL) (p=0.022) on the right foot and a larger rearfoot load (RfL) (p=0.011) on the left foot compared to non-sport controls (CTR). Moreover, a larger forefoot load (FfL) (p=0.001) on the right foot respect to left one was found in the BOX group, with the inversion of the RfL to FfL ratio (p=0.001) between two feet, while no significant differences were found in the CTR group. These findings, associated to a significantly larger center of foot angle (COF) in the BOX group, may indicate an anticlockwise rotation of the anatomical structures above the ankle joint of the right hemisoma respect to the left one, that appears to be consistent with the orthodox stance. Eventually, the BOX group showed a larger centre-of-pressure sway area (COPsa) in the OE condition than what measured in the CE and a significant difference in Romberg Index (BOX< CTR).
The results of this study seem to confirm the theory of neuromuscular plasticity imprinted by the repetitive movements and long-lasting postures. Moreover, competitive boxers show an increase of proprioceptive function and a decrease of visual dependence on the postural control.
