The purpose of this study was to analyze the effects of 2 days/week versus 4 days/week of Whole Body Vibration (WBV) during eight weeks of WBV training on health-related quality of life (SF-36), balance and lower body strength, as well as short-term detraining (3 weeks) on balance and lower body strength among older adults. Thirty-four older adults were randomly assigned to a control group (Con...

INTRODUCTION Regular physical activity can reduce age-related functional decline, as well people's risk for chronic diseases such as coronary heart disease, hypertension, colon cancer, and diabetes. The objective of this study was to estimate the level of participation in aerobic, muscle-strengthening, and flexibility activities among Americans aged 50 years or older. METHODS Using population...

BACKGROUND Although exercise is a commonly recommended treatment for ankylosing spondylitis (AS), little is known about the effectiveness of unsupervised recreational and back exercises. We examined the effects of recreational exercise and back exercises on patient-reported pain severity, stiffness severity, and functional disability in a prospective longitudinal study of 220 patients with AS. ...

OBJECTIVE To study the effects of an aquatic therapy program with different frequencies (2 vs 3 days per week) in chronic low back pain. DESIGN [corrected] Non-randomized comparison trial. SETTING Sport and spa community health club. SUBJECTS Fifty-four adults with chronic low back pain (48.9 ± 10.0 years). INTERVENTION Eight-week aquatic therapy program. OUTCOME MEASURES Pain (visual...

Respiratory work is increased during exercise under water and may lead to respiratory muscle fatigue, which in turn can compromise swimming endurance. Previous studies have shown that respiratory muscle training, conducted five days per week for four weeks, improved both respiratory and fin swimming endurance. This training (RRMT-5) consisted of intermittent vital capacity breaths (twice/minute...

The aim of this pilot study was to analyze the off-training physical activity (PA) profile in national elite German U23 rowers during 31 days of their preparation period. The hours spent in each PA category (i.e., sedentary: <1.5 metabolic equivalents (MET); light physical activity: 1.5-3 MET; moderate physical activity: 3-6 MET and vigorous intense physical activity: >6 MET) were calculated fo...

Despite much debate about the productivity effects of flexible working and the regulation of working hours little attention is paid to temporal variance in productivity. This paper explains why one might expect to see productivity differences across days of the week. Although there is scant direct evidence on day-of-week productivity effects, studies suggest that the timing of labour inputs acr...
