Effects of exercise training and montelukast in children with mild asthma.

abstract：:This study examined the association between aerobic, caloric exercise expenditure and life status (living vs deceased) as well as the prevalence rates of hypertension (HBP) and cardiovascular disease (CVD) in former male athletes (ATH) and non-athletes (N-ATH). The initial survey for this study was done in 1952. Follo...

abstract：BACKGROUND:Stress fracture (SF) injuries in new recruits have long been attributed to low bone mineral density (BMD). Low areal BMD assessed using two-dimensional dual-energy x-ray absorptiometry imaging, however, reflects structural density and is affected by smaller measures of bone geometry. Recent studies support a...
