The linear regression method yielded a valid model that included all three variables in this study (F(2) = 9.512; p less then 0.001).ConclusionBased on these findings, it is possible to conclude that birthdate, demographic rate and HDI are important factors in the identification and development of soccer players in Brazil.In the present study, the relationship between subjective vitality and subjective happiness was examined through the mediating role of hope among 168 Turkish university students. To collect data, the Subjective Vitality Scales, the Dispositional Hope Scale, the Oxford Happiness Questionnaire Short Form, and a demographic information form were used. Bootstrapped mediation analysis was conducted to test the mediating role of hope in the link between subjective vitality and subjective happiness. Results indicated that hope was a significant mediator in the vitality-happiness link such that subjective vitality was positively related to hope, which in turn was positively related to subjective happiness. Some implications were discussed in the context of the theory and practice of subjective vitality and hope.Aim 106 donor conceived people (DCP) responded to an anonymous survey study that examined the impact of the method of genetic identity disclosure and age at the time of the disclosure on their emotional wellbeing, familial relations, and perceptions of donor conception practices.Methods Participants were asked to select the way in which they were informed they are DCP and the age group at which this occurred, and then were asked to select strongly agree, agree, neither agree or disagree, disagree, or strongly disagree in response to 26 statements that examined their perceptions of the topics listed above. Responses were grouped based on the age of genetic identity disclosure and the method of genetic identity disclosure, then numerically compared by assigning each type of response a number. Statistical analysis using repeatedmeasures ANOVA was performed to identify differences among these factors.Results This analysis revealed that most participants 18 ≥ years and most participants who discovered their genetic identity through means other than through their parent(s) had worse emotional wellbeing and familial relations. However, most participants among all categories had a negative perception of donor conception practices.Conclusion Continued work is needed to understand and support the growing DCP population.

This study examined the effects of resistance training (RT) performed at 24 or 48h post-match on recovery in female soccer players.

In a randomized cross-over design, 10 professional female soccer players undertook matches followed by three conditions Control (no RT), RT-24h and RT-48h post-match. RT was a high-speed and low-load session, consisting of 3 sets of 6 repetitions of lower-body exercises at 50%1RM. During training, one exercise (half-squat) was performed on a force platform to determine mean and peak forces. Tests were undertaken pre, 24, 48 and 72h post-match including countermovement jump (CMJ), 20m sprint, C-reactive protein (CRP) and delayed onset muscle soreness (DOMS). Two-way repeated-measures ANOVA and Effect size (ES) analyses compared the time-course of recovery.

Despite no significant differences between conditions, ES for changes from pre to 72h were larger for CMJ, 10 and 20m sprint time, and DOMS in RT48h (ES=0.38-2.13) than in RT24h (ES=0.08-0.66) and in Control (ES=0.09-0.36). No differences in forces of half-squat exercise existed between conditions (p>0.05; ES=0.05-0.06).

The trend for suppressed recovery of speed, power and perceptual responses at 72h post-match suggests RT48h is less ideal in female soccer players, particularly during congested micro-cycles.

The present study aims to examine the immediate effects of heading.Methods 30 recreational male soccer players were divided into three groups that undertook 20 consecutive headers with a soft (8.8 psi), hard (16.2 psi), or no (control) ball. A battery of neuropsychological tests was completed before and after heading King-Devick, trail-making (TM) (A, B), digit span (DS) and spatial span (SS) (forward, backward).Results Significant increase in the time (M = 4.44 s) and errors (M = 1.45) for the King-Devick test within the hard and soft groups, although there was no significant difference for TM-A and TM-B. PF-07321332 Significant decline for SS forward within the hard and soft groups (M= -16%), although the declines for SS backward (M = -16%), DS forward (M= -23%) and DS backward (M = -25%) were present only for the hard group (ps less then .05).Discussion While outside of regular match-play, this study showed that heading negatively influenced one indicator of a suspected concussion (King-Devick), as well as working memory (DS, SS) that is essential for daily life. These findings contribute to the growing debate surrounding heading safety.This study used small-sided games (SSGs) to induce fatigue and therefore, reduce the action capabilities of Varsity soccer players (n= 20). The aim was to examine the effect of compromised action capabilities on defensive movement response in a 1-vs-1 scenario. Action capabilities were assessed via countermovement jumps (CMJ), 5-m acceleration, 20-m sprint and a Change of Direction (COD) test. Defensive movement response was measured via a Soccer-Specific Anticipation Test (SSAT). Following SSGs, significant reductions were observed in jump (p=.04, d=.31), acceleration (p less then .001, d=.98), and sprint (p less then .001, d=.66) performance. Significantly, players tended to move earlier in the SSAT following SSGs (p=.049, d=.66). Furthermore, to examine the distinct effect of reductions in each action capability, players were categorised according to whether SSGs had a worthwhile change in CMJ, acceleration, sprint or COD performance. For each of the four measures, movements tended to be initiated earlier following SSGs, although pre-/post-SSGs differences were not significant (p =.08-.51), moderate to large effect sizes were shown (d=.56-.84). These findings intimate that compromised action capabilities influence the timing of the movement response of defensive players in 1-vs-1 situations.Background The Nordic hamstring exercise (NHE) has emerged as a popular intervention for improving eccentric hamstring strength, however recent literature suggests there is a potential for an increase in injury risk during subsequent exercise.Methods To quantify the influence of pre-exercise NHE on the electromyographical response of the hamstrings, 10 male soccer players completed an experimental trial comprising 6 sets x 5 repetitions of NHE prior to the completion of a 45 minute soccer-specific protocol. Post-exercise NHE were performed in the experimental and control (no pre-exercise NHE) trials. Electromyographic (EMG) response (integrated, mean and peak amplitude) of the biceps femoris to the pre- and post-exercise NHE and the soccer-specific exercise protocol was quantified.Results Integrated (P= 0.025) and mean (P= 0.020) EMG elicited a significant main effect for time in the soccer-specific protocol with higher values during the first 15 mins indicative of a fatigue effect. However, there was no trial x time interaction (P ≥ 0.78). There was no difference between trials in the EMG response to pre-exercise (P≥ 0.30) or post-exercise (P≥ 0.16) NHE trials.Conclusions Therefore, although previous studies suggest performing pre-exercise NHE might impair maximal strength metrics, the current study's results suggest that it does not impair the electromyographical response to subsequent soccer-specific exercise or NHE repetitions.PurposeThis study investigated sources of variability in the overall and phase-specific running match characteristics in elite rugby league. MethodsMicrotechnology data were collected from 11 Super League (SL) teams, across 322 competitive matches within the 2018 and 2019 seasons. Total distance, high-speed running (HSR) distance (>5.5 m·s-1), average speed, and average acceleration were assessed. Variability was determined using linear mixed models, with random intercepts specified for player, position, match, and club. ResultsLarge within-player coefficients of variation (CV) were found across whole match, ball-in-play, attack and defence for total distance (CV range = 24% to 35%) and HSR distance (37% to 96%), whereas small to moderate CVs (≤10%) were found for average speed and average acceleration. Similarly, there was higher between-player, -position, and -match variability in total distance and HSR distance when compared with average speed and average acceleration across all periods. All metrics were stable between-teams (≤5%), except HSR distance (16% to 18%). The transition period displayed the largest variability of all phases, especially for distance (up to 42%) and HSR distance (up to 165%). ConclusionAbsolute measures of displacement display large within-player and between-player, -position, and -match variability, yet average acceleration and average speed remain relatively stable across all match-periods.Objectives To investigate if heading frequency and impact biomechanics in a single session influence the concentration of serum neurofilament light (NF-L), a sensitive biomarker for axonal damage, up to 7 days after heading incident at ball velocities reflecting basic training drills.Methods Forty-four males were randomized into either control (n = 8), 10 header (n = 12), 20 header (n = 12) or 40 header (n = 12) groups. Linear and angular head accelerations were quantified during heading. Venous blood samples were taken at baseline, 6 h, 24 h and 7 days after heading. Serum NF-L was quantified using Quanterix NF-L assay kit on the Simoa HD-1 Platform.Results Serum NF-L did not alter over time (p = 0.44) and was not influenced by number of headers [p = 0.47; mean (95% CI) concentrations at baseline 6.00 pg · ml-1 (5.00-7.00 pg · ml-1); 6 h post 6.50 pg · ml-1 (5.70-7.29 pg · ml-1); 24 h post 6.07 pg · ml-1 (5.14-7.01 pg · ml-1); and 7 days post 6.46 pg · ml-1 (5.45-7.46 pg · ml-1)]. There was no relationship between percentage change in NF-L and summed session linear and angular head accelerations.Conclusion In adult men, heading frequency or impact biomechanics did not affect NF-L response during a single session of headers at ball velocities reflective of basic training tasks.Severe traumatic abdominal injuries and duodenal ruptures are relatively rare in soccer and can be easily missed and turn into a life-threatening condition. All team physicians need to be familiar with the warning sign in these situations. This report aims to report a case, discuss the diagnostic and treatment process and the return to play protocol.During a professional female soccer team training session, the injury occurred while the player's epigastrium was hit hardly by the opponent's knee. In the first evaluation, there was only mild epigastrium pain without any other sign. Eventually, pain exacerbated, nausea and vomiting were added. All the initial evaluation (Physical examination, abdominal X-ray, ultrasonography, blood tests) were normal. Eventually, she developed abdominal guarding and underwent abdominopelvic computed tomography with intravenous contrast where Duodenal rupture becomes evident. She underwent laparotomy and full duodenal repair and discharged from the hospital in good health.For the return to play determination in such injuries, the abdomen should not be imposed on any trauma for about 6 months, so while the player can start a self-training session firstly without a ball and then with a ball, she is not allowed to play or train with others for 6 months.
