Despite its crucial importance, scientists interested in the limitations of human physical
performance have only just started to give the field of oxygen uptake kinetics the attention it …

One of the major features of an effectively functioning physiological system is its ability to
respond to a particular stressor with rapid response characteristics. For example, during …

Today, we live in an atmosphere that contains 20.9% oxygen (O2). In contrast, when the
solar system was created approximately 4.6 billion years ago (Dickerson, 1978), the …

Near-infrared spectroscopy (NIRS) can be used to measure muscle oxygen consumption
(mVO2) using arterial occlusions. The recovery rate of mVO2 after exercise can provide an …

The Cosmed AquaTrainer® snorkel, in connection with the K4b 2 analyzer, is the most
recent instrument used for real time gas analysis during swimming. This study aimed to test if …

The purpose of the present study was to examine the effects of a high-or low-carbohydrate
(CHO) diet on performance, aerobic and anaerobic contribution, and metabolic responses …

At the onset of muscular exercise, the kinetics of pulmonary O2 uptake (V̇o2P) reflect the
integrated dynamic responses of the ventilatory, circulatory, and neuromuscular systems for …

The common perception of V̇O2 kinetics analysis is that it is too complex and difficult to
grasp. Consequently, in laboratories around the world a great deal of data has been …

To estimate the anaerobic alactic contribution in a 200 m middle distance swimming trial by
means of two different methods based:(1) on the fast component of the ̇ VO _ 2 off-kinetics …

Daily life is full of challenges in which the energy demands of the working muscles might
quickly go from rest to substantial loads. It is critical, therefore, to understand the factors that …
