The effectiveness of fundamental movement training interventions in adolescents is not fully understood. Functional Movement Screen (FMS) may provide means evaluating the such programs alongside traditional tests physiological performance. Twenty-two children completed FMS, plank, side sit and reach, multistage fitness test. Participants were pair matched by total FMS score assigned to control or intervention. intervention group received a weekly 4 × 30-minute sessions with an emphasis on...

Fifty-six females were randomly allocated to either SAND or LAND group. Thirty-nine completed programme twice weekly eligible for analysis. Two-dimensional projection (FPPA), countermovement (CMJ) reactive strength index (RSI) (10–5 repeated test) measured 1-week pre- post-intervention....

Isometric knee-flexor testing is commonplace in soccer, yet data to inform choice of knee-flexion angle are limited. This study aimed compare peak force production and muscle activation between two isometric tests. To force, 43 male soccer players (age 21.5 ± 5 years; stature 180.3 6.3 cm; body mass 74.6 8.9 kg) completed 3 × 5-second maximal efforts on the Nordbord device (Vald Performance) with a 0- (ISO-Prone) 30-degree (ISO-30) knee angle, respectively. activation, further 13 trained...

Little is known about the responses of girl athletes to training interventions throughout maturation. This study evaluated group and individual an 8-week, mixed-methods, high-intensity interval (HIIT) programme in football players. Thirty-seven players (age 13.4 ± 1.5 years) were tested for 20-m speed, repeated-sprint ability, change-of-direction speed level 1 yo-yo intermittent recovery (YYIR). Players subcategorised into before-, at- after-PHV (peak height velocity) based on maturity...

Competence in fundamental movement skills is essential to enable children be physically active. We investigated the effect of an integrated skill with a strength training intervention on children's skills. Seventy-two (53% female) 10- 11-year-old from three primary schools assented take part this study (87% compliance). Schools were randomly allocated control (no intervention; n = 21), (FMS) (n 18) or FMS and (FMS+; 20) group. Interventions delivered twice weekly for four weeks, addition...

The Nordic Hamstring exercise program (NHP) is an evidence-based injury prevention protocol. aims of this study were to (a) report professional English football clubs' practices hamstring strategies, (b) identify the NHP implementation in football, and (c) understand reasons for NHP's inclusion or exclusion. An electronic survey was completed by 53 91 (58%) clubs. Forty-three clubs had a formal with NH (95%), eccentric strength exercises (93%), functional training (81%) most common methods...

The school playground can promote PA for large numbers of children. This study identifies areas the that children visited at break-times, decisions according to gender and influence contextual environmental variables on levels. a culturally diverse primary was observed during morning break-times lunchtimes. Counts sedentary, LPA, MVPA episodes, contexts in which they occurred were recorded using system observing play leisure youth (SOPLAY). Ball sports had higher counts boys (mean ± SD; 9.9...

Within-Season Variation of Fitness in Elite Youth Female Soccer Players The within-season variation fitness measures elite youth female soccer players (<18 years age) has not been investigated previously. Further knowledge this area could allow more effective periodization training, whilst also enabling coaches to design appropriate long-term athlete development models. This study the test performance players. In players, acceleration, sprint and CoD decreased over course a season, RSA...

The aim was to assess factor structure of player-reported fatigue and quantify within-subjects association between changes in training load measures next day at different time points an elite football season. Using longitudinal research design, twenty-four professional footballers, mean (SD) age 25.7 (3.4) years, were monitored during their competitive season, including pre-season. Player-reported data session ratings perceived exertion (session-RPE) collected via a mobile application....

ABSTRACT Soccer match play dictates that players possess well-rounded physical capacities. Therefore, player development plans must consider developing several fitness components simultaneously. Effective individualization of training is likely facilitated with appropriate profiling; therefore, a time-efficient and informative testing battery highly relevant for practitioners. Advances in knowledge technology over the past decade have resulted refinements practices used by practitioners...
