The purpose of this study was to describe the longitudinal (10 yr) decline in aerobic power [maximal O(2) uptake (Vo(2 max))] and anaerobic threshold [ventilatory threshold (T(Ve))] of older adults living independently in the community. Ten years after initial testing, 62 subjects (34 men, mean age 73.5 +/- 6.4 yr; 28 women, 72.1 +/- 5.3 yr) achieved Vo(2 max) criteria during treadmill walking ...

The purpose of this study was to determine if inspiratory muscle training (IMT) alters the oxygen cost of breathing (Vo(2RM)) during voluntary hyperpnea. Sixteen male cyclists completed 6 wk of IMT using an inspiratory load of 50% (IMT) or 15% placebo (CON) of maximal inspiratory pressure (Pi(max)). Prior to training, a maximal incremental cycle ergometer test was performed to determine Vo(2) a...

This study examined the differences in fat and carbohydrate oxidation during running and cycling at the same relative exercise intensities, with intensity determined in a number of ways. Specifically, exercise intensity was expressed as a percentage of maximum workload (WL(max)), maximum oxygen uptake (%VO(2max)), and maximum heart rate (%HR(max)) and as rating of perceived exertion (RPE). Ten ...

Treatment with recombinant human erythropoietin (rhEpo) induces a rise in blood oxygen-carrying capacity (CaO(2)) that unequivocally enhances maximal oxygen uptake (VO(2)max) during exercise in normoxia, but not when exercise is carried out in severe acute hypoxia. This implies that there should be a threshold altitude at which VO(2)max is less dependent on CaO(2). To ascertain which are the me...

OBJECTIVE To examine venous partial pressure of oxygen (PvO(2)), transcutaneous oxygen tension (tcPO(2)), and VO(2)MAX in a normobaric environment after a single hyperbaric oxygen (HBO(2)) treatment. METHODS This was a prospective study of conditions after the intervention compared with baseline. The participants were 10 moderately trained (VO(2)MAX = 57.6 ml/kg/min) men. Two HBO(2) treatment...

PURPOSE Validity of the 20-meter multi stage shuttle run test (20-m MST) has not been studied in Nepalese population. The purpose of this study was to validate the applicability of the 20-m MST in Nepalese adult females. METHODS Forty female college students (age range, 20.42 ~24.75 years) from different colleges of Nepal were recruited for the study. Direct estimation of VO(2) max comprised ...

background: the aim of this study was to investigate the effects of exercise training on maximum aerobic capacity, resting heart rate (rhr), blood pressure and anthropometric variables of postmenopausal women with breast cancer. methods : twenty nine women with breast cancer who received surgery, chemotherapy and radiotherapy with current hormone therapy were divided into two groups; interventi...

The accumulation of visceral fat is independently associated with an increased risk for cardiovascular disease. The aim of this study was to determine whether the loss of visceral adipose tissue area (VAT; computed tomography) is related to improvements in maximal O(2) uptake (VO(2 max)) during a weight loss (250-350 kcal/day deficit) and walking (3 days/wk, 30-40 min) intervention. Forty obese...

The purpose of present study was to compare fat oxidation rate during and after three different exercise intensities. Eight non-athlete male students (aged, 19.7±1.8 yr; height, 174.3±5.1 cm; weight, 64.5±7 kg; VO max, 40.1±4.4 ml/kg/min) participated in this study as subjects. Each subject was exercised at 55, 65 and 75% 2 VO max on treadmill at three separate days those days which elapsed by ...
