To evaluate the effect of short-duration, high-load resistive exercise, with and without whole body vibration on lumbar muscle size, intervertebral disk and spinal morphology changes, and low back pain (LBP) incidence during prolonged bed rest, 24 subjects underwent 60 days of head-down tilt bed rest and performed either resistive vibration exercise (n = 7), resistive exercise only (n = 8), or ...

We analyzed the effects of gravitational unloading on muscular fatigability and the effectiveness of resistive vibration exercise to counteract these changes. Changes in knee extensor fatigability as a consequence of 8 weeks of horizontal bedrest with or without daily resistive vibration exercise were evaluated in 17 healthy male volunteers. Bedrest increased fatigability (% decrease in maximal...

OBJECTIVE To evaluate the effects of stretching and/or resistive exercise, followed by detraining, on the functional status of older people. METHODS Forty-five subjects were divided into four groups: control (CG; n=13; 66±6 years), stretching (SG; n=10; 69±6 years), resistive exercise (RG; n=13; 69±5 years), and resistive exercise and stretching (RSG; n=9; 66±5 years). The CG did not perform ...

OBJECTIVE To assess the influence of 2 single exercise sessions on blood pressure in sedentary normotensive individuals: one of resistive exercise training (circuit weight training) and the other of aerobic exercise training. METHODS Using ambulatory blood pressure monitoring, this study assessed 25 individuals as follows: in a controlled situation at rest (ABPM 1); after resistive exercise t...

The resistive work of breathing against an external load during inspiration (WR(I)) was measured at the mouth, during sub-maximal exercise in healthy participants. This measure (which excludes the elastic work component) allows the relationship between resistive work and power, ventilation and exercise modality to be explored. A total of 45 adult participants with healthy lung function took par...

The purpose of this study was to elucidate the influence of inspiratory muscle fatigue on muscle sympathetic nerve activity (MSNA) and blood pressure (BP) response during submaximal exercise. We hypothesized that inspiratory muscle fatigue would elicit increases in sympathetic vasoconstrictor outflow and BP during dynamic leg exercise. The subjects carried out four submaximal exercise tests: tw...

Background & Aims: Chondromalacia patella is one of the chronic dysfunctions of the patella femoral joint which is the most common anterior knee syndrome especially among the youth. Muscle weakness and proprioception deficit are the subsequent problems of this dysfunction. Thus, the aim of this study was the investigation and comparison of the effects of vibration training and resistive exercis...

Bone loss associated with disuse during bed rest (BR), an analog of space flight, can be attenuated by exercise. In previous studies, the efficacy of either aerobic or resistive exercise countermeasures has been examined separately. We hypothesized that a regimen of combined resistive and aerobic exercise during BR would prevent bone resorption and promote bone formation. After a 20-day ambulat...

Microgravity-induced lumbar paraspinal muscle deconditioning may contribute to back pain commonly experienced by astronauts and may increase the risk of postflight injury. We hypothesized that a combined resistive and aerobic exercise countermeasure protocol that included spinal loading would mitigate lumbar paraspinal muscle deconditioning during 60 days of bed rest in women. Sixteen women und...
