Purpose: The proper neuromuscular recruitment patterns of hip and knee muscles are essential for dynamic stabilization of the knee. According to the kinematic chain, weakness in the performance of one motor segment can affect other segments of motion. Thus, the aim of this study was to compare the isometric strength of selected muscles of lower extremities in the hyperpronated foot with t...

introduction: ski is a fast sport with a high risk of falling. the purpose of this study is to investigate the relationship of core strength with static and dynamic balance in snowboarders. materials and methods: forty male athletes participated in this study with a history activity of at least 6 seasons in snowboard skiing sport (mean age 26.85±3.30yr, height 180.45±6.08cm, weight 79.86±6.14kg...

[Purpose] The importance and effect of hip joint geometry on hip abductor muscle strength are well known. In addition, other perioperative factors are also known to affect hip abductor muscle strength. This study examined the relative importance of factors affecting hip abductor muscle strength after total hip arthroplasty. [Subjects and Methods] The subjects were 97 females with osteoarthritis...

BACKGROUND/AIM Traumas and war injuries, next to chronic occlusive artery disease and diabetes mellitus-derived complications, are the most frequent cause of the lower limbs amputation. They affect mostly younger population that need a higher level of activities as compared with the elderly. Medical rehabilitation is very significant for the muscle performance improvement in this population pro...

introduction: the most common manifestation of disturbed neurological function following stroke is motor weakness. muscle weakness has been implicated as a factor underlying deficits in gait performance in subjects who have suffered strokes . the purpose of this study was to investigate the relationship between involved lower extremity isometric muscle strength and two functional tasks: gait ab...

BACKGROUND Adductor-related pain is the most common clinical finding in soccer players with groin pain and can be a long-standing problem affecting physical function and performance. Hip adductor weakness has been suggested to be associated with this clinical entity, although it has never been investigated. PURPOSE To investigate whether isometric and eccentric hip strength are decreased in s...

Purpose: The purpose of this study was to investigate the relationship between hip and knee strength with knee valgus angle during drop jump in elite female athletes. Methods: Forty female athletes (mean ± SD age, 21.5 ± 1.99 years height, 169.08 ± 8.25 cm body mass, 61.05 ± 10.06 kg) participated in this study. Isometric hip and knee muscles strength were evaluated using standard clinical...

PURPOSE This study aimed to determine whether the tendency of women to exhibit higher knee extensor moments relative to hip extensor moments during the deceleration phase of landing can be explained by the relative strength of the knee and hip extensors. METHODS Forty recreationally active individuals participated in this study (20 men and 20 women). The maximum isometric strength of the knee...
