Context:Risk of anterior cruciate ligament (ACL) injuries in young female athletes increases with age, appearing to peak during maturation. Changes in hip muscle strength and range of motion (ROM) during this time may contribute to altered dynamic movement patterns that are known to increase risk of ACL injuries. Understanding the longitudinal changes in hip strength and ROM is needed to develop appropriate interventions to reduce the risk of ACL injuries.Objective:To examine the longitudinal changes in hip strength and ROM in female youth soccer players.Design:Longitudinal descriptive study.Setting:Field setting.Participants:14 female youth soccer athletes (14.1 ± 1.1 y, 165.8 ± 5.3 cm, 57.5 ± 9.9 kg) volunteered as part of a multiyear risk factor screening project.Main Outcome Measures:Clinical measures of hip strength and ROM were collected annually over 3 consecutive years. Passive hip internal rotation (IR), external rotation (ER), abduction (ABD), and adduction (ADD) ROM were measured with a digital inclinometer. Isometric hip ABD and extension (EXT) strength were evaluated using a hand-held dynamometer. Separate repeated-measures ANOVAs compared hip strength and ROM values across 3 consecutive years (P < .05).Results:As youth female soccer players increased in age, there were no changes in normalized hip ABD (P = .830) or EXT strength (P = .062) across 3 consecutive years. Longitudinal changes in hip ROM were observed with increases in hip IR (P = .001) and ABD (P < .001), while hip ADD (P = .009) and ER (P < .001) decreased.Conclusions:Anatomical changes at the hip occur as youth female soccer players increase in age. While there are no changes in hip strength, there is an increase in hip IR and ABD ROM with a concomitant decrease in hip ER and ADD ROM. The resulting asymmetries in hip ROM may decrease the activation and force producing capabilities of the hip muscles during dynamic activities, contributing to altered lower extremity mechanics known to increase the risk of ACL injuries.

Context:After years of focusing on the management of anterior cruciate ligament (ACL) injuries, the most common soccer-related injuries, the orthopedic community has concluded that soccer players have a wide range of variation in joint biomechanics and has thus started to focus research efforts on the morphological factors that might contribute to ACL trauma. One such factor is decreased hip-rotation range of motion (ROM), which may be due to compensatory musculoskeletal changes occurring in response to longstanding soccer practice since childhood.Objective:This study sought to assess decreased hip rotation and the influence of stretching exercises on the behavior of the hip joint in players of the youth soccer categories of a Brazilian soccer team.Design:Randomized clinical trial.Setting:University hospital.Patients:262 male soccer players.Interventions:Subjects were randomly allocated into 2 groups—control or a stretching program.Main Outcome Measures:Subjects were reassessed after 12 wk.Results:The findings suggest that hip-rotation ROM decreases over the years in soccer players. In the study sample, adherence to a stretching program improved only external hip-rotation ROM in the nondominant limb.Conclusion:Playing soccer can restrict rotation ROM of the hip, and adherence to stretching exercises may decrease the harmful effects on the hip joints.

Background: Youth soccer injuries are common and of increasing concern, with sport specialization occurring at younger ages. Limited research is available regarding overuse injuries and risk factors in young female athletes. Purpose: To identify the number and rate of overuse injuries in female soccer players (ages 12-15 years), describe the anatomic location and type of injury, and evaluate contributing risk factors. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 351 female youth soccer players, ages 12 to 15 years, from Washington State were evaluated from 2008 to 2012. Players with lower extremity overuse injuries were identified through weekly emails and were interviewed by telephone to obtain data on injury type and body region. We evaluated the association between overuse injuries and preseason risk factors, including joint hypermobility, hip and knee muscle strength, and jump biomechanics, using Poisson regression to estimate relative risk (RR) and 95% CIs. Results: The incidence rate for first-time lower extremity overuse injuries was 1.7 per 1000 athlete-exposure hours (AEH; 95% CI, 1.4-2.2), and that for repeat injuries was 3.4 per 1000 AEH (95% CI, 2.1-5.6). Knee injuries accounted for 47% of overuse injuries. Increased valgus was associated with a 3.2-fold increased risk (95% CI, 1.52-6.71) for knee injury. A 1–standard deviation (SD) increase in hamstring strength was associated with a 35% decreased risk (RR, 0.65; 95% CI, 0.46-0.91) for overuse knee injuries, and a 1-SD increase in quadriceps strength was associated with a 30% decreased risk (RR, 0.70; 95% CI, 0.50-0.98). A 1-SD increase in hip flexor strength was associated with a 28% decreased risk (RR, 0.72; 95% CI, 0.51-1.00) for overuse knee injuries, and a 1-SD increase in external rotation strength was associated with a 35% decreased risk (RR, 0.65; 95% CI, 0.46-0.91). Playing on more than 1 soccer team was associated with a 2.5-fold increased risk (95% CI, 1.08-5.35) for overuse knee injuries, and participating in other physical activities was associated with a 61% decreased risk (odds ratio, 0.39; 95% CI, 0.15-0.81). Conclusion: In this study, lower extremity overuse injuries in female youth soccer players affected primarily the knee. Lower knee separation distance, decreased lower extremity strength, and playing on more than 1 soccer team increased injury risk.

El estudio de los factores psicológicos relacionados con el rendimiento deportivo tiene un importante recorrido en la literatura científica. Conocer si existen diferencias entre hombres y mujeres deportistas, cuáles son estas, y en qué aspectos se manifiestan es una cuestión que podría ayudar a mejorar la labor de entrenadores y técnicos deportivos. El objetivo de este estudio es determinar si existen diferencias de género en el perfil psicológico de futbolistas juveniles relacionado con el rendimiento deportivo. Se utilizó un diseño descriptivo transversal. La muestra objeto de estudio estuvo formada por un total de 329 jugadores juveniles de fútbol (46.8% varones y 53,2% mujeres), con una edad media de 17.02 (±1.50) años;. Para la evaluación de las características psicológicas se utilizó el Cuestionario Características Psicológicas Relacionadas con el Rendimiento Deportivo (CPRD). Los resultados de este estudio indican que existen diferencias estadísticamente significativas entre chicos y chicas en control de estrés (CE), influencia de la evaluación del rendimiento (IER) y en cohesión de equipo (CH). Los jugadores chicos manifiestan puntuaciones mayores que las jugadoras chicas en CE, es decir, gestionan mejor el estrés propio de la competición, y en IER, es decir, los jugadores chicos gestionan mejor que las jugadoras chicas el impacto que supone la evaluación de su rendimiento, el que hacen los otros (entrenadores, compañeros, padres/madres, etc.) y el que se hace a sí mismo. Sin embargo, las jugadoras chicas presentan mejores puntuaciones en CH, es decir, manifiestan una mayor tendencia a trabajar en grupo y fortalecer el equipo. The study of psychological factors related to sports performance has an important track record in the scientific literature. Knowing if there are differences between male and female athletes, what they are, and in what aspects they manifest is an issue that could help improve the work of coaches and sports technicians. The aim of this study is to determine if there are gender differences in the psychological profile of youth soccer players related to sports performance. A descriptive cross-sectional design was used. The sample under study was formed by a total of 329 youth soccer players (46.8% male and 53,2% female), with an average age of 17.02 (± 1.50) years. The Psychological Characteristics Questionnaire Related to Sports Performance (CPRD) was used to evaluate psychological characteristics. The results of this study indicate that there are statistically significant differences between male and female in stress control (CE), influence of performance evaluation (IER) and in team cohesion (CH). The male players show higher scores than the female players in CE, that is, they better manage the stress of the competition, and in IER, that is, the male players manage better than the female players the impact of evaluating their performance, the one that others do (coaches, partners, fathers / mothers, etc.) and the one that makes itself. However, female players have better CH scores, that is, they show a greater tendency to work in groups and strengthen the team. O estudo de fatores psicológicos relacionados ao desempenho esportivo tem um histórico importante na literatura científica. Saber se existem diferenças entre atletas masculinos e femininos, o que são e em que aspectos eles se manifestam é uma questão que pode ajudar a melhorar o trabalho de treinadores e técnicos esportivos. O objetivo deste estudo é determinar se existem diferenças de gênero no perfil psicológico de jovens jogadores de futebol relacionados ao desempenho esportivo. Foi utilizado um desenho descritivo de corte transversal. A amostra estudada foi composta por um total de 329 jogadores de futebol juvenil (46,8% masculino e 53,2% feminino), com idade média de 17,02 (± 1,50) anos. O Questionário de Características Psicológicas Relacionadas ao Desempenho Esportivo (CPRD) foi utilizado para avaliar as características psicológicas. Os resultados deste estudo indicam que existem diferenças estatisticamente significantes entre meninos e meninas no controle do estresse (EC), influência da avaliação de desempenho (IER) e na coesão da equipe (HC). Os jogadores pequenos apresentam pontuações mais altas do que as jogadoras da CE, ou seja, administram melhor o estresse da competição, e no IER, ou seja, os jogadores pequenos gerenciam melhor do que as jogadoras o impacto de avaliar seu desempenho , o que os outros fazem (treinadores, parceiros, pais / mães, etc.) e o que se faz. No entanto, as jogadoras têm melhores pontuações no HC, ou seja, mostram maior tendência a trabalhar em grupo e fortalecer a equipe

Vertical Jump Height

Abstract The study aim was to analyze the effects of successive matches on the internal match load, stress tolerance, salivary cortisol concentration and countermovement vertical jump height in twelve youth soccer players (16.6 ± 0.5 yr; 175 ± 8 cm; 65 ± 8 kg) who performed four official matches within a four day-period with a 24-h recovery interval between the matches. The internal match load, monotony index and competitive strain, as well as stress tolerance were examined. Saliva samples were collected and countermovement vertical jump height was assessed 60 min pre and 30 min post each match; delta of salivary cortisol and countermovement vertical jump height for each match were analyzed. Salivary cortisol was analyzed using an enzyme-linked immunosorbent assay. The results of ANOVA with repeated measures showed no differences between matches for the internal match load (p > 0.05). The scores of the monotony index and competitive strain were 4.3 (±2.3) and 8104 (±6795) arbitrary units, respectively. There was no difference for stress tolerance between matches (p > 0.05). Delta values of salivary cortisol were not different among the assessed matches (F(3,33) = 1.397, p = 0.351, η2: 0.09); however, delta of countermovement vertical jump height decreased from match 1 to match 4 (F(3,33) = 8.64, p < 0.001, η2: 0.44). The current findings suggest that participating in four successive matches, with 24-h of recovery in between, may not lead to changes in stress tolerance and salivary cortisol of youth players, but it may induce a decrease in players’ jumping performance after the fourth match.

The ability of young athletes to effectively cope with stressors is crucial for sustained sport enjoyment and participation, and parents play a key role in providing coping support. However, there is limited evidence for coping interventions directed at both youth athletes and their parents. The purpose of this study was to implement a coping workshop for youth athletes and also engage parents to provide them with information to support the development of coping skills among young athletes. Athlete–parent dyads from a high-performance soccer academy were assigned to either a 4-wk coping intervention or a control group using a matched quasi-experimental design. Survey data were analyzed using 2-factor repeated-measures ANOVAs and multiple-regression analyses. Results indicated that lower parental pressure and greater coping self-efficacy predicted lower stress in youth athletes. However, findings for the intervention in reducing overall stress and perceptions of parental pressure were not significant. Future coping intervention studies should address study design considerations related to timing, intervention modalities, and skill level of youth athletes.
