An urban population sample of 40 to 79-year-old men and women was investigated to evaluate the influence of age and activity level on muscle strength and endurance and to establish a reference material. During the investigation 144 persons were tested bilaterally, except for ankle strength, when only the right side was examined. Isometric muscle strength was determined in the knee extensors and...

BACKGROUND Fall-related injuries associated with aging are a serious clinical and economic problem. The Flo-Dynamics Movement System (FDMS), which consists of eight movements with a water-filled device, may be a useful low-impact exercise suited for older persons. This study investigated the effects of the FDMS regimen with the Wun-Jo trainer on measures of strength, flexibility, and balance in...

ABSTRACT Introduction: Vertical jump is inherent to the practice of high and demands great capacity force generation work knee muscles, especially quadriceps muscle. Due this demand, imbalances between extensor flexor muscles may be present, leading an overload musculotendinous structures joint. Therefore, it necessary establish characteristics isokinetic muscle strength in joint these athletes...

OBJECTIVE The purpose of this study was to determine if individuals with unilateral functional ankle instability had decreased ability to maintain postural sway, as well as decreased isokinetic eccentric strength of ankle evertors and invertors. DESIGN AND SETTING SUBJECTS WITH NO PREVIOUS HISTORY OF ANKLE INJURY WERE COMPARED WITH SUBJECTS WITH FUNCTIONAL ANKLE INSTABILITY ON THE FOLLOWING T...

The isokinetic strength of the elbow and knee extensors and flexors was measured in 200 healthy 45- to 78-yr-old men and women to examine the relationship between muscle strength, age, and body composition. Peak torque was measured at 60 and 240 degrees/s in the knee and at 60 and 180 degrees/s in the elbow by use of a Cybex II isokinetic dynamometer. Fat-free mass (FFM) was estimated by hydros...

Volleyball players performed numerous repetitions of spike actions, which uses and requires strong and explosive force, and control of the muscles of the shoulder, lower back, and legs. Muscle imbalance is one of the main causes of sport injuries. The purpose of this study was to assess isokinetic muscle functions in male volleyball players. We thus aim to accurately evaluate their muscle funct...
