Previous research has demonstrated the importance of both dynamic and isometric maximal strength and rate of force development (RFD) in athletic populations. The purpose of this study was to examine the relationships between measures of isometric force (PF), RFD, jump performance and strength in collegiate football athletes. The subjects in this study were twenty-two men [(mean ± SD):age 18.4 ±...

OBJECTIVE To compare the cervical isometric strength, fatigue endurance and range of motion of adult and under-18 age-grade front-row rugby players to inform the development of a safe age group policy with particular reference to scrummaging. DESIGN Cross-sectional cohort study. SETTING 'Field testing' at Murrayfield stadium. PARTICIPANTS 30 high-performance under-18 players and 22 adult ...

abstract introduction: chronic neck pain is one of the most common problems among computer users. the aim of this research was evaluation of the effect of 8 weeks selected exercise therapy and self treatment with pamphlet programs on the strength and range of motion (rom) of the neck in the patients with chronic neck pain. methods: sixty-six patients with chronic neck pain (mean (±sd) age 39.19...

Most studies about human responses to mechanical vibrations involve whole-body vibration and vibration applied perpendicularly to the tendon or muscle. The aim of the present study was to verify the effects of mechanical vibration applied in the opposite direction of muscle shortening on maximal isometric strength of the flexor muscles of the elbow due to neural factors. Conventional isometric ...

BACKGROUND The aim of the present study was to compare the changes in voluntary strength (isometric, concentric, and eccentric) and functional mobility in response to maximal isokinetic eccentric-only resistance training to those elicited by maximal isometric-only or maximal isokinetic concentric-only resistance training in older adults. METHODS Twelve women (73 +/- 7 years) and 18 men (73 +/...

We evaluated the relationship between altered foot function and knee osteoarthritis through a specific comparison of toe grip strength in older women with and without knee osteoarthritis. Participants were 120 women with knee osteoarthritis (OA group) and 108 healthy community-dwelling women with no history of knee pain and lower limb surgery (control group). The following factors and outcome v...

BACKGROUND One of the rationales behind using strength training in the treatment of adolescents with Patellofemoral Pain (PFP) is that reduced strength of the lower extremity is a risk factor for PFP and a common deficit. This rationale is based on research conducted on adolescents >15 years of age but has never been investigated among young adolescents with PFP. OBJECTIVES To compare isometr...

PURPOSE This study investigated the correlation between isometric muscle strength, gross motor function, and gait parameters in patients with spastic cerebral palsy and to find which muscle groups play an important role for gait pattern in a flexed knee gait. MATERIALS AND METHODS Twenty-four ambulatory patients (mean age, 10.0 years) with spastic cerebral palsy who were scheduled for single ...
