Aging women show nonlinear declines in fitness.

Although the aging-related decline in cardiorespiratory fitness cannot be avoided, regular exercise remains its primary determinant, compose Sui et al.

Aging women show nonlinear declines in fitness, activity levels By MedWire Reporters Physical activity levels and cardiorespiratory fitness in women usually do not decline in a linear way with age, research shows. After age 60 years, fitness levels in women rapidly declined, whereas physical activity levels were highest in 50-year-old women and plateaued at age group 60, report investigators. ‘The menopause transition seems to be a crucial period to initialize and promote physical activity, for sedentary women especially, as the accelerated decline in both activity and fitness begins around this time,’ say Xuemei Sui and co-workers.Heparin offers been the traditional locking solution. Several small studies have got assessed whether citrate and heparin are equally efficacious for maintaining catheter patency,10,11 but the interpretation of the outcomes was limited because the studies had a short follow-up period and included both uncuffed and cuffed central venous catheters. Recombinant tissue plasminogen activator offers been used mainly to treat catheter thrombosis12-14; in one small randomized trial, it had been shown to be more advanced than heparin as a locking answer.15 The fairly high cost of rt-PA and its own theoretical potential to trigger bleeding, as well as the morbidity and mortality connected with catheter malfunction and infection, justify the need for more definitive evidence of the efficacy of rt-PA as a locking solution.
