“…Additionally, the participants in our study performed similar to high school and collegiate athletes, US Marines, and healthy active adults, 23,26,27 but they performed slightly worse than elite soccer players. 28 Some of our findings were different from those of Leyk et al 19 In our sample, the percentage of individuals with a history of inactivity decreased with age. This may be due to selection bias, as those who remain in the military are required to maintain the required physical fitness and weight standards.…”

Context: Although inactivity, being overweight, smoking, and a history of injury are identified as risk factors for poor health and injury, few authors have examined their association on physical performance. Young adults may be more likely to adopt healthier lifestyles if they understand the effect of health behaviors on performance.Objective: To determine the association of being overweight, smoking, inactivity, and a history of injury with physical performance.Design: Cross-sectional study.Setting: Military population. Patients or Other Participants: Active-duty service members (N ¼ 1466; 1380 men, 86 women; age ¼ 24.7 6 5.0 years; body mass index ¼ 26.7 6 3.4 kg/m 2 ). Main Outcome Measure(s): Participants performed 8 measures (the triple-crossover hop for distance, the 6-m timed-hop test, the Functional Movement Screen, the Lower Quarter YBalance Test, the Upper Quarter Y-Balance Test, and the 3-event Army Physical Fitness Test) for evaluation of endurance, strength, muscular endurance, power, agility, balance, and motor control. Participants were categorized based on the number of health risk factors present. Using an analysis of covariance, we assessed the relationship between risk factors and physical performance with age and sex as covariates.Results: Compared with those who had no risk factors (27.9% of men, 34.9% of women), physical performance was worse in those who had 1, 2, or 3 to 4 risk factors present by 4.3%, 6.7%, and 10.3%, respectively. Decrements in performance for those with 3 to 4 risk factors ranged from 3.3% to 14.4%.Conclusions: An unhealthy lifestyle habit or a history of injury was negatively associated with physical performance. Physical performance decrements were associated with the number of risk factors present. Understanding how risk factors contribute to decreased physical performance may enable clinicians to improve compliance with injury-prevention programs in occupational settings in which a young and relatively healthy workforce may be more concerned about performance than health.Key Words: functional movement, health, injury prediction, risk factors Key PointsPhysical performance was worse in those with health risk factors; performance was lowest in those with 3 to 4 health risk factors. Risk factors can be responsible for a 10-to 47-point decrease in scores on the Army Physical Fitness Test. Future researchers should determine if strategies focused on improving performance may be more effective in decreasing health risk factors in a relatively young and healthy population. S ubstantial evidence exists that risk factors negatively affect health. Specifically, physical inactivity, being overweight, smoking, and a history of injury have been identified as having negative associations with health.1-4 Less clear is the association between these health risk factors and physical performance. Defining that association is of particular interest to organizations that value both health and physical performance. The US Army, in addition to funding health care for its members, must e...

RESuMoIntrodução: Assimetrias na capacidade de produção de força entre músculos dos membros inferiores e fadiga muscular podem favorecer a ocorrência de lesões em atletas de futebol. Considerando-se que existem diferenças individuais determinadas pelas diversas funções exercidas pelos jogadores, é possível que a presença de assimetrias de força e fadiga muscular esteja relacionada ao posicionamento em campo. Objetivos: 1) Investigar diferenças na assimetria de pico de torque (PT), na assimetria de trabalho (T) e no índice de fadiga ( ABStRAct Introduction: Strength asymmetry among the muscles of the lower limbs and muscle fatigue may predispose soccer players to injuries. Regarding the individual differences determined by diverse roles performed by players, it is possible that the presence of asymmetries of muscle strength and fatigue is related to playing position. Objectives: 1) To investigate differences in asymmetry of peak torque (PT), work asymmetry (W) and fatigue index (FI) of knee extensors and flexors of professional soccer players according to their positioning in field; 2) To determine if FI of knee flexors is higher than

“…Así, diversos trabajos han observado que el rendimiento deportivo declina tanto con el ROM extremo "hipermovilidad" (Gannon y Bird, 1999;Snyder, McLeod y Hartman, 2006) como con el ROM limitado por una menor extensibilidad muscular "cortedad muscular" (Young, Clothier, Otago, Bruce y Liddell, 2003;Rahnama, Lees y Bambaecichi, 2005;Zakas, Vergou, Zakas, Grammatikopoulou y Grammatikopoulou, 2002;Zakas, Vergou, Grammatikopoulou, Sentelidis y Vamvakoudis, 2003). Además, la cortedad muscular ha sido correlacionada con la lesión muscular (Bradley, Olsen y Portas, 2007;Dadebo, White y George, 2004;Ekstrand, Wiktorsson, Oberg y Gillquist, 1982;Rahnama et al, 2005;Witvrouw, Danneels, Asselman, D'Have y Cambier, 2003), la lesión ligamentosa como el esguince de tobillo (Ekstrand y cols., 1982;Pope, y cols., 1998; Okamura y cols., 2014) y la rotura del ligamento cruzado anterior (Ellera, Vieira y Becker, 2008), y la lesión por sobrecarga como la fascitis plantar, la tendinopatía rotuliana y aquilea, la periostitis tibial, el síndrome de la cintilla iliotibial y el síndrome de dolor femoropatelar (Witvrouw, Mahieu, Roosen y McNair, 2007;Probst, Fletcher y Seeling, 2007;Johanson, Baer, Hovermale y Phouthavong, 2008).…”
