Stretching, while enhancing joint flexibility, may also decrease the hamstring: quadriceps (H:
Q) strength ratio, which is used to identify knee strength imbalances and lower extremity
muscle and ligament injury risk in the practice of sports and other physical activities …

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 …

Aim: Hamstring muscle injury is the main injury related to sports requiring sprint
acceleration. In addition, hamstring muscles have been reported to play a role in horizontal
force production during sprint acceleration performance. The aim of the present study was to …

The purpose of this study was to examine the effect of fatiguing exercise on sex-related
differences in the function of hamstring and quadriceps muscles at several angular velocities
and joint angles. Physically active participants (50 male: 28.7±4.5 y, 1.82±0.07 m, 82.3±6.87 …

The risk of anterior cruciate ligament injury in female handball players is high. Fatigue of
active stabilizers and increases in joint laxity are often mentioned in the literature as causal
factors. However, no studies have been carried out on this population. Our objective is to …

In professional football clubs, information from many different sources has to be joined for
informed decisions on team management. A central club management information system
(CMIS) could help to support the employees at the club with information that they need for …

Isokinetic hamstring-to-quadriceps (H: Q) ratios are frequently used to assess knee muscle
strength imbalances and risk of injuries/re-injuries. The use of peak torque (PT) or total work
(TW) to estimate joint stability may lead to different results because of the differences …

Background: Soccer players are required to perform explosive and powerful movements as
the game is very competitive and intermittent nature. Functional hamstring to quadriceps
strength ratio can plays a significant role to perform these movements. The imbalance of this …

Resistance training is often recommended for combined increases in traditional and
alternative hamstrings-to-quadriceps (H: Q) ratios in order to reduce knee strength
imbalance and associated hamstrings and knee ligament injury risk. The aim of this study …

OBJECTIVE The objective of this study was to investigate muscle performance of the
quadriceps and hamstrings muscles, as well as lower limb function in participants with
meniscal lesions that required partial meniscectomy. It was of particular interest to assess …
