“…v 2.05 ). The equations listed above are determined from reanalyzing the original data (92,299,338,431,438) with power functions over the aerobic speed range. As indicated by Figure 11, metabolic power increases sharply as a function of speed and, at similar velocities, it is greater for leg kicking (both underwater and at the surface), slightly lower for the front crawl and lower by a significant amount in kayaking and rowing.…”

Water covers over 70% of the earth, has varying depths and temperatures and contains much of the earth's resources. Head-out water immersion (HOWI) or submersion at various depths (diving) in water of thermoneutral (TN) temperature elicits profound cardiorespiratory, endocrine, and renal responses. The translocation of blood into the thorax and elevation of plasma volume by autotransfusion of fluid from cells to the vascular compartment lead to increased cardiac stroke volume and output and there is a hyperperfusion of some tissues. Pulmonary artery and capillary hydrostatic pressures increase causing a decline in vital capacity with the potential for pulmonary edema. Atrial stretch and increased arterial pressure cause reflex autonomic responses which result in endocrine changes that return plasma volume and arterial pressure to preimmersion levels. Plasma volume is regulated via a reflex diuresis and natriuresis. Hydrostatic pressure also leads to elastic loading of the chest, increasing work of breathing, energy cost, and thus blood flow to respiratory muscles. Decreases in water temperature in HOWI do not affect the cardiac output compared to TN; however, they influence heart rate and the distribution of muscle and fat blood flow. The reduced muscle blood flow results in a reduced maximal oxygen consumption. The properties of water determine the mechanical load and the physiological responses during exercise in water (e.g. swimming and water based activities). Increased hydrostatic pressure caused by submersion does not affect stroke volume; however, progressive bradycardia decreases cardiac output. During submersion, compressed gas must be breathed which introduces the potential for oxygen toxicity, narcosis due to nitrogen, and tissue and vascular gas bubbles during decompression and after may cause pain in joints and the nervous system.

“…These will be the variables that will be examined in the proposed investigation as potential predictors of performance. Previous research reports moderate to strong negative correlations between 2km rowing performance and peak power output, oxygen uptake, fat free mass and body fat percentage (6,10,14,23,24,30).…”

“…Because the 2km race typically requires maximal effort, the aerobic energy system will likely not be able to satisfy the energy demands leading to an increased reliance on glycolysis. (13,14,38) This reliance on glycolysis will increase lactic acid, hydrogen ions, non-metabolic CO2 and ventilation. (41) The ventilatory breakpoint is a non-invasive correlate of the anaerobic threshold that has previously been validated through research.…”

“…Starting from this concept, di Prampero analysed the energetics of running, cycling, skating, swimming and the maximal performances (records) that can be attained in each mode of locomotion (Celentano et al 1974;di Prampero 1986;di Prampero et al 1971di Prampero et al , 1974di Prampero et al , 1976di Prampero et al , 1979di Prampero et al , 1986Pendergast et al 1977, to cite only the pioneering papers). More recently, he used this knowledge to develop a quantitative model of best performances in human locomotion .…”

This paper reports an analysis of the principles underlying human performances on the basis of the work initiated by Pietro Enrico di Prampero. Starting from the concept that the maximal speed that can be attained over a given distance with a given locomotion mode is directly proportional to the maximal sustainable power and inversely proportional to the energy cost of locomotion, we discuss the maximal powers (and capacities) of anaerobic (lactic and alactic) and aerobic metabolisms and the factors that limit them, and the factors affecting the energy cost of various locomotion modes. Special attention is given to the role of air resistance and frictional forces. Finally, computation of performance speed is discussed along the approach originally developed by di Prampero.
