Lungless salamanders (4.1 g) were exercised on a treadmill enclosed in a Plexiglas respirometer at a range of speeds (0.05-0.24 km/h). O2 consumption (VO2) was determined continuously by open-flow respirometry. At the onset of exercise VO2 increased to a "steady state" in approximately 2-5 min. VO2 (ml O2 X g-1 X h-1) increased linearly with speed (S), VO2 = 2.3 (S) + 0.1 (r2 = 0.74). The minim...

This study examined the effects of aerobic exercise on lipid levels in premenopausal and postmenopausal women. Fifty healthy middle-aged women (mean age, 50 years) were randomly assigned to 12 weeks of either aerobic exercise (walking and jogging) or nonaerobic strength exercise (circuit Nautilus training). Concentrations of total cholesterol, high density lipoprotein cholesterol, low density l...

Declines in muscular strength resulting from reduced neural activity may influence the reduction in aerobic capacity in older men. However, there has been little investigation into the relationship between muscular strength and economy of movement during aerobic exercise in elderly subjects. Thus, the purpose of this study was to investigate the possible relationship between strength, aerobic p...

Purpose: It has been established that physical exercise generally improves the physical performance of older people. This finding has led to an increase in studies into the most efficient forms of exercise. The aim of this study was to compare the efficiency of three types of exercise: aerobic, strength and muscle power, in improving the functional capacity of older people. Methods: A study was...

Background The aim of the study was to determine the physical effort and energy expenditure needed over a working period of 45-60 min, specifically for the occupational activity of cleaning. The effort was demonstrated in absolute terms (V'O2), in relation to the involved person's maximum physical capacity (peak V'O2) and in relation to the individual aerobic-anaerobic threshold (V'O2 at VT1, t...

  Purpose: The aim of this study was to investigate the effect of four weeks supplementation of   vitamin C on serum levels of total antioxidant capacity and malondialdehyde among inactive   men after an eccentric exercise.   Materials and Methods: Twenty non-athletic healthy volunteer men (24 ± 1.6 years old,   22.59 ± 2.62 body fat percentage and 48.96 ± 3.58 mL/kg/min maximum oxygen uptake) ...

Background—A study was undertaken to determine whether swimming training improved aerobic capacity, exercise induced bronchoconstriction (EIB), and bronchial responsiveness to inhaled histamine in children with asthma. Methods—Eight children with mild or moderate asthma participated in swimming training every day for six weeks. The intensity of training was individually determined and set at 12...

Weibel and Taylor's theory of symmorphosis predicts that the structural components of the respiratory system are quantitatively adjusted to satisfy, but not exceed, an animal's maximum requirement for oxygen. We tested this in the respiratory system of the adult migratory locust Locusta migratoria by comparing the aerobic capacity of hopping and flight muscle with the morphology of the oxygen c...
