The effect of knee extensor and ankle plantar flexor fatigue on dynamic balance in active elderly males
The purpose of this study was to examine the effect of knee extensor and ankle plantar flexor fatigue on dynamic balance among active elderly males. Fifteen healthy individuals having age of 72±6.57 years, height of 168.4±4.8 cm and weight of 70.5±7.4 kg without history of injuries at lower extremity, participated in this study. Knee extensor and ankle plantar flexor muscles fatigued with f...
متن کاملMedian nerve behavior at different wrist positions among older males
The effect of wrist flexion-extension on the median nerve appearance, namely the cross-sectional area (MNCSA) and the longitudinal (D1) and vertical (D2) diameters, was investigated among older adults (N = 34). Ultrasound examination was conducted to examine the median nerve at different wrist angles (neutral; and 15°, 30°, and 45° extension and flexion), in both the dominant and nondominant ha...
متن کاملKnee Strength and Slip Severity in Young and Older Adults
INTRODUCTION Falls initiated by slips are a major cause of serious injury in the elderly population (Moyer, 2005). Studies have shown a possible correlation between lower extremity muscle strength, which decreases with age, and slip severity (Lockhart, 2005). However, these studies did not focus on the knee, which plays an important role in sliprecovery attempts (Moyer, 2005/2006). Thus, the go...
متن کاملPlantar flexor activation capacity and H reflex in older adults: adaptations to strength training.
The purpose of this study was to investigate whether the voluntary neural drive and the excitability of the reflex arc could be modulated by training, even in old age. To this aim, the effects of a 16-wk strengthening program on plantar flexor voluntary activation (VA) and on the maximum Hoffman reflex (H(max))-to-maximum M wave (M(max)) ratio were investigated in 14 elderly men (65-80 yr). Aft...
متن کاملHealthy older adults have insufficient hip range of motion and plantar flexor strength to walk like healthy young adults.
Limited plantar flexor strength and hip extension range of motion (ROM) in older adults are believed to underlie common age-related differences in gait. However, no studies of age-related differences in gait have quantified the percentage of strength and ROM used during gait. We examined peak hip angles, hip torques and plantar flexor torques, and corresponding estimates of functional capacity ...
