Sažetak Previous studies have utilized screening values of 10-15% of lower-extremity side-
to-side strength asymmetry in soccer players with conflicting results. The purpose of this
study was to determine differences in screening values for side-to-side asymmetry in soccer …

Commonly used injury risk prediction tests such as the hamstring‐to‐quadriceps (H: Q)
strength ratio appear to be poor predictors of non‐contact injury. However, these tests are
typically performed in a non‐fatigued state, despite accumulated fatigue being an important …

Abstract Change Of Direction Speed (CODS) and Reactive Agility (RA) are two determining
factors in the ability of young soccer players. We aimed to verify if CODS and RA could be
useful in order to establish the best young soccer player field position. Ninety-two elite …

Chronic low back pain (CLBP) has been related to hips, trunk and spine strength
imbalances and/or low flexibility levels. However, it is not clear if the assessment and
normalization of these variables are effective for prevention of low back pain (LBP) episodes …

Although side-to-side asymmetry of the shoulder rotators calculated by independent peak
torque (IPT) has been used for interpretation of injury risks in athletes, it may not measure
strength through the entire range of motion (ROM) tested. The aim of this study was to …

The hamstrings-to-quadriceps muscle strength ratio calculated by peak torque has been
used as an important tool to detect muscle imbalance, monitor knee joint stability, describe
muscle strength properties and functionality, and for lower extremity injury prevention and …

Background: The effects of proprioceptive neuromuscular facilitation (PNF) stretching on
muscle imbalance are not fully understood. The aim of this study was to examine the acute
effects of PNF stretching on knee extension and flexion peak torque (PT), as well as the …

The ability to jump high with precision is an important component of the ballet dancer's
technique. The aim of this study was to evaluate the effect of a modified ballet class on
strength and jumping ability in high level female dancers. Seventeen female ballet students …

BACKGROUND: Vertical jumping capacity is important in modern soccer to gain advantage
over opponent during the defensive and offensive activities. Predictors of jumping capacity
in soccer players are not well studied. OBJECTIVE: The main aim of our study was to …

Résumé Contexte La difficulté de comparer les études sur l'isocinétisme vient du nombre
important de protocoles d'évaluation, d'une part et, des seuils des ratios utilisés d'autre part.
Notre première étude a montré qu'un protocole d'évaluation «type» est largement utilisé par …
