Cerebral oxygenation during intermittent supramaximal exercise

Respiratory Physiology & Neurobiology, 2004
This study examined cerebral deoxygenation during intermittent supramaximal exercise in six healthy male subjects (age: 27.2 +/- 0.6 years (mean +/- S.E.). The subjects performed seven times exercise at an intensity corresponding to 150% of maximal oxygen uptake (VO2max) on cycle ergometer (30 s exercise/15 s rest). Cerebral oxygenation was measured by

Blood lactate accumulation in intermittent supramaximal exercise

European Journal of Applied Physiology and Occupational Physiology, 1988
Blood lactate accumulation rate and oxygen consumption have been studied in six trained male runners, aged 20 to 30 years. Subjects ran on a treadmill at a rate representing 172 +/- 5% VO2max for four 45 s sessions, separated by 9 min rest periods. Oxygen consumption was measured throughout.

Nocturnal Heart Rate Variability Following Supramaximal Intermittent Exercise

International Journal of Sports Physiology and Performance, 2009
Purpose:To assess the effect of supramaximal intermittent exercise on long-term cardiac autonomic activity, inferred from heart rate variability (HRV).Methods:Eleven healthy males performed a series of two consecutive intermittent 15-s runs at 95% VIFT (i.e., speed reached at the end of the 30-15 Intermittent Fitness Test) interspersed with 15 s of ...

Effect of supramaximal exercise on excess postexercise O2 consumption

Medicine & Science in Sports & Exercise, 1992
This study was undertaken to determine the effect of high intensity exercise on the time course and magnitude of excess postexercise O2 consumption (EPOC). Six healthy male subjects performed three intermittent 2-min exercise bouts on a cycle ergometer at 108% of VO2max with 3-min rest periods (3 x 2 min).

Alterations in blood volume following short-term supramaximal exercise

Journal of Applied Physiology, 1984
To investigate the role of high-intensity intermittent exercise on adaptations in blood volume and selected hematological measures, four male subjects aged 19–23 yr [peak O2 consumption (VO2max) = 53 ml X min-1 X kg-1] performed supramaximal (120% VO2max) cycle exercise on 3 consecutive days.

Lactate accumulation in response to supramaximal exercise in rowers

Scandinavian Journal of Medicine & Science in Sports, 2012
The aim of this study was to test (a) three methods to estimate the quantity of lactate accumulated (QLaA) in response to supramaximal exercise and (b) correlations between QLaA and the nonoxidative energy supply assessed by the accumulated oxygen deficit (AOD).

Effects of supramaximal exercise on blood glucose levels during a subsequent exercise

European Journal of Applied Physiology and Occupational Physiology, 1991
The purpose of the present investigation was to examine the effects of hyperglycemia induced by supramaximal exercise on blood glucose homeostasis during submaximal exercise following immediately after. Six men were subjected to three experimental situations; in two of these situations, 3 min of high-intensity exercise (corresponding to 112, SD 1 ...

Exercise stimulus increases ventilation from maximal to supramaximal intensity

European Journal of Applied Physiology and Occupational Physiology, 1995
This study investigated the influence of an exercise stimulus on pulmonary ventilation (VE) during severe levels of exercise in a group of ten athletes. The altered ventilation was assessed in relation to its effect on blood gas status, in particular to the incidence and severity of exercise induced hypoxaemia.

Heart rate response to breath-holding during supramaximal exercise

European Journal of Applied Physiology and Occupational Physiology, 1989
The cardiovascular responses to breath-holding (BH) during short-lasting supramaximal exercise (415 W) on a cycle ergometer were investigated in 15 healthy male subjects. The arterial oxygen saturation, heart rate (HR), endtidal PO2 and PCO2 were continuously monitored.

Supramaximal exercise mobilizes hematopoietic progenitors and reticulocytes in athletes

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2005
