BACKGROUND AND PURPOSE Physical therapists commonly attempt to reduce and prevent low back pain by "improving" individuals' lumbar posture. To investigate the physical therapy clinical practice of attempting to "improve" lumbar posture, measures of passive tissue stiffness and angular deformation during activities of daily living were used. PARTICIPANTS The lumbar spine posture of 150 univers...

The purpose of this study is to examine ways in which electrical stimulation, both transcutaneously and via implanted stimulators, may be used to treat spasticity . Spasticity is one of the complications which frequently follows CNS (central nervous system) lesion, and it is commonly identified in the following ways : The involved muscles develop a pathological resistance to passive stretch . T...

28 The present study investigated the role of muscle metaboreceptor activation on human 29 thermoregulation by measuring core temperature thresholds and slopes for sweating and 30 cutaneous vascular responses during passive heating associated with central and peripheral 31 mechanisms. Six male and eight female subjects inserted their lower legs into hot water (43°C) 32 while wearing a water per...

PURPOSE This study examined the effects of hypohydration and moderate hyperthermia (core temperature elevation) on anaerobic exercise performance in a temperate environment. METHODS Eight active males completed two passive heat exposure trials (180 min, 45 degrees C, 50% rh) with (EUH) and without (HYP) fluid replacement. A single 15-s Wingate anaerobic test (WAnT) was used to assess anaerobi...

Background – We have previously demonstrated opposite e¡ ects of exercise training in stable and progressive pulmonary hypertension (PH). Here we investigated cellular changes which may underlie the opposite e¡ ects of exercise training by focusing on right ventricular myolament protein phosphorylation and function. Methods and results – Histological analyses revealed exercise training in progr...

The purpose of this study was to compare an electrostimulated to an active recovery strategy after a submaximal isometric fatiguing exercise. Nineteen healthy men completed three sessions (separated by at least 4 weeks) which included a knee extensors provocation exercise consisting of 3 sets of 25 isometric contractions. Contraction intensity level was fixed respectively at 60%, 55% and 50% of...

The aim of the present study was to determine whether training-related alterations in muscle mechanoreflex activation affect cardiac vagal withdrawal at the onset of exercise. Eighteen male volunteers divided into 9 controls (26 +/- 1.9 years) and 9 racket players (25 +/- 1.9 years) performed 10 s of voluntary and passive movement characterized by the wrist flexion of their dominant and non-dom...

[Purpose] To evaluate the effects of early passive range of motion exercise on the function of upper extremities and activities of daily living in patients with acute stroke. [Methods] A total of 37 patients with acute stroke in intensive care units, were assigned to the experimental group (n=19) and control group (n=18). The experimental group performed passive range of motion exercise twice a...

BACKGROUND Active transport is a convenient way to incorporate physical activity in adolescents' daily life. The present study aimed to investigate which psychosocial and environmental factors are associated with walking, cycling, public transport (train, tram, bus, metro) and passive transport (car, motorcycle, moped) over short distances (maximum eight kilometres) among older adolescents (17-...
