Skeletal muscle voluntary contractions (VC) and electrical stimulations (ES) were compared in eight healthy men. High-energy phosphates and myoglobin oxygenation were simultaneously monitored in the quadriceps by interleaved (1)H- and (31)P-NMR spectroscopy. For the VC protocol, subjects performed five or six bouts of 5 min with a workload increment of 10%(More)
The purpose of this study was to estimate the effects of intense and regular physical activity on locomotor system modifications. Tennis, with its unilateral solicitations, allows a more precise examination of specific localized development. Ten professional tennis players were compared with sedentary age-matched students. Muscular modifications were(More)
The extent to which an oral load of glucose is absorbed from the gut and oxidized during prolonged exercise is a matter of controversy. Four healthy volunteers, 18-28 yr, were submitted on 4 different days to a 105-min treadmill exercise at 22, 39, 51, and 64% of their individual VO2max. After 15 min adaptation to exercise, they received orally 100 g(More)
OBJECTIVES To determine Coll2-1, Coll2-1NO(2) and myeloperoxydase (MPO) levels in serum of patients with knee or hip osteoarthritis (OA) before the surgery, 3 months and 1 year after knee or hip replacement. METHODS Coll2-1, Coll2-1NO(2) and MPO were measured in 103 patients with isolated symptomatic knee or hip OA candidates for joint replacement. Sera(More)
OBJECTIVE The aim of this study was to assess the efficacy of gaseous cryotherapy following total knee arthroplasty (TKA) and to compare it to routinely used strategies for applying cold therapy. PATIENTS AND METHODS Sixty-six patients undergoing primary unilateral TKA were randomized into three groups and received "gaseous cryotherapy (GC)", "cold pack"(More)
Within the domain of physical therapy, it has been mum isometric voluntary torque (MIVT) from each quadriceps. proposed that electrical stimulation programs might Then, MBF and MMRO2 were evaluated by PET be beneficial toward minimizing both muscular atroduring a bilateral simultaneous isometric exercise, phy and loss of oxidative capacity as a result of(More)
To address the question of whether the increased plasma concentration of interleukin 6 (IL-6) following strenuous muscular work could be related to exercise-induced muscle damage, 5 moderately active male volunteers underwent two isokinetic exercise sessions in the eccentric mode, separated by a period of 3 weeks during which the subjects underwent five(More)
BACKGROUND/AIMS Latissimus dorsi (LD) transfer in the case of breast reconstruction remains frequently used because this muscle provides a good size source of tissue in reconstructive surgery. Given that, the consequences of the LD removal on shoulder function and the actual loss of maximal strength developed must be investigated. METHODS Twenty women (50(More)
Neuromuscular electrical stimulation (NMES) was studied with positron emission tomography (PET) and H(2)(15)O in the quadriceps muscle of 11 men. The subjects were submitted to simultaneous bilateral isometric contraction (5 s)-rest (5 s) cycles for 12 min, with a workload corresponding to 5% of quadriceps maximal isometric voluntary torque (QMIVT) for one(More)
OBJECTIVE A systematic review of the literature about chronic fatigue syndrome (CFS). METHODS A search of the Medline database (via Ovid and PubMed) with the key words chronic fatigue syndrome, diagnosis, classification, epidemiology, etiology, physiopathology, metabolism, microbiology, immunology, virology, psychology, drug therapy, rehabilitation, and(More)
