SummaryIn 1923, Hill and Lupton pointed out that for Hill himself, ‘the rate of oxygen intake due to exercise increases as speed increases, reaching a maximum for the speeds beyond about 256 m/min. At this particular speed, for which no further increases in O2 intake can occur, the heart, lungs, circulation, and the diffusion of oxygen to the active muscle-fibres have attained their maximum activity. At higher speeds the requirement of the body for oxygen is far higher but cannot be satisfied… Expand
Determination of the velocity associated with the longest time to exhaustion at maximal oxygen uptake
The velocity which elicits the longest time to exhaustion at V˙O2max (CV′) was determined and these two velocities were correlated (r’= 0.88, P =‬0.05). Expand
Time to Exhaustion at the VO2max Velocity in Swimming: A Review
Assessing TLim-vVO2max, together with the anaerobic threshold and the biomechanical general parameters, will allow a larger spectrum of testing protocols application, helping to build more objective and efficient training programs. Expand
Maximal endurance time at VO2max.
Endurance time atVO2max can be realistically modeled by a curve, which permits estimation of several parameters of interest; such as the minimal running velocity sufficient to elicit VO2max, and that velocity for which endurance at VO2 max is the longest. Expand
The Influence of Exercise Duration at V̇O2 max on the Offtransient Pulmonary Oxygen Uptake Phase During High Intensity Running Activity
VΔ75 is the velocity at which the longer the duration of the time at V̇O2 max, the longer is the off-transient phase of oxygen uptake kinetics, and it may be possible that at vΔ50 there is not an accumulated oxygen deficit during the plateau of V⩽O2 at O 2 max and that the duration at VΔ100, could be too short to induce an accumulating oxygen deficit affecting the oxygen recovery.

The importance of improvements in the aerobic fitness parameters to the enhancement of endurance performance is highlighted, as are the training methods that may be considered optimal for facilitating such improvements. Expand
A Fast-Start Pacing Strategy Speeds Pulmonary Oxygen Uptake Kinetics and Improves Supramaximal Running Performance
Middle-distance running performances with a duration of 2–3 min are improved and response time is faster when a fast-start is adopted, and the relationship between time and distance/speed through log-log modelling was used. Expand
The relationship between vLTP and vVO2max during an incremental test to exhaustion in professional endurance runners
The minimal running velocity at which maximal oxygen uptake (VO2max) is elicited during an incremental test to exhaustion has been used to prescribe training for competitive middle- and long-distanceExpand
Effect of exercise intensity on relationship between VO2max and cardiac output.
VO2max was not attained with the same central and peripheral factors in exhaustive exercises, and tlimDelta50 did not elicit the maximal Q, which might be taken into account if the training aim is to enhance the central factors of VO2max using exercise intensities eliciting VO2 max but not necessarily Qmax.

Effect of training in humans on off- and on-transient oxygen uptake kinetics after severe exhausting intensity runs
The physiological factors best correlated with the increased performance after training were vLT for t Lim90 and vVO2max for tlim95 and the cardio-dynamic added to the metabolic phase and the time constants of oxygen kinetics in the on-transient phase decreased significantly after training. Expand
Oxygen kinetics and modelling of time to exhaustion whilst running at various velocities at maximal oxygen uptake
The tlimV�’O2max was a bi-phasic function of velocity, with a peak at 100% νV˙O 2max, and depended on a balance between the time to attain V˙ O2max and the timeto exhaustion tlim. Expand
