This study investigated differences in average VO2 of maximal effort interval running to maximal effort constant rate running at lactate threshold matched for time. The average VO2 and distance covered of 10 recreational male runners (VO2max: 4158 ± 390 mL · min(-1)) were compared between a maximal effort constant-rate run at lactate threshold (CRLT), a maximal effort interval run (INT) consist...

The logarithmic nature of the allometric equation suggests that metabolic rate scaling is related to some fractal properties of the organism. Two universal models have been proposed, based on (1) the fractal design of the vasculature and (2) the fractal nature of the 'total effective surface' of mitochondria and capillaries. According to these models, basal and maximal metabolic rates must scal...

background: resistive inspiratory muscle training (rimt) is a well-known technique for rehabilitation of patients with chronic obstructive pulmonary disease (copd). incentive spirometry is another technique with potential viability for this application, but there is limited evidence in support of its efficacy in the rehabilitation of copd patients. aim: the objective of this study was to compar...

1. Twenty-four patients were studied at around 7 days after musculoskeletal injuries in order to define the nature of the impairment of sensitivity to insulin. Insulin was infused at 6, 35, 200 or 1200 m-units min-1 m-2 for 2 h and the plasma glucose concentration was 'clamped' at 5 mmol/l. Forearm (uninjured) glucose extraction and blood flow were measured, and whole-body substrate oxidation a...

We investigated maximal Prym varieties on finite fields by attaining their upper bounds on the number of rational points. This concept gave us a motivation for defining a generalized definition of maximal curves i.e. maximal morphisms. By MAGMA, we give some non-trivial examples of maximal morphisms that results in non-trivial examples of maximal Prym varieties.
