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.

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 training on metabolic outcomes in obese adults

Journal of Sports Sciences, 2016
The purpose of this study was to evaluate the effects of 6 weeks of supramaximal exercise training (SET) on performance variables and metabolic changes in sedentary obese adults. Twenty-four obese adults were randomly allocated into a non-trained (NT) [n = 12; body mass index (BMI) = 33(3)] and SET group [n = 12; BMI = (33(2)]. After baseline metabolic

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.

Post-exercise Hypotension Produced by Supramaximal Interval Exercise is Potentiated by Angiotensin Receptor Blockers

International Journal of Sports Medicine, 2019
AbstractWe studied the effects of supramaximal interval exercise (SIE) with or without antihypertensive medication (AHM) on 21-hr blood pressure (BP) response. Twelve hypertensive patients chronically medicated with AHM, underwent three trials in a randomized order: a) control trial without exercise and substituting their AHM with a placebo (PLAC); b ...

Increased Ventilatory Efficiency in Supramaximal Compared to Graded Exercise in Athletes

Research Quarterly for Exercise and Sport
Background: Supramaximal constant work rate tests (CWR) elicit intense hyperventilation, thus potentially up-shifting ventilation (⩒E)-to-carbon dioxide (CO2) responses when compared to graded exercise tests (GXT) in athletes. We predicted higher ventilatory efficiency on supramaximal CWR using a new method, challenging the classic orthodox ...

[The effect of supramaximal exercise on the recovery kinetics of lactate].

Schweizerische Zeitschrift fur Sportmedizin, 1991
Blood lactate recovery curves from muscular exercise can be described by a sum of two exponential terms consisting in a rapidly increasing and a slowly decreasing component. A two-compartment model consisting of the previously working muscles and the remainder of the lactate space furnishes the simplest but nevertheless realistic explanation of this ...

The effect of normocapnic hypoxia and the duration of exposure to hypoxia on supramaximal exercise performance

European Journal of Applied Physiology and Occupational Physiology, 1993
Two investigations were designed that (a) evaluated the effect of the respiratory alkalosis that accompanies breathing an hypoxic (H) gas mixture and (b) examined the influence of the duration of breathing this H mixture on the subsequent performance of 45 s supramaximal dynamic exercise.
