The effect of self-regulation on high intensity exercise
… if the use of self-regulated (SR) rest during high intensity training (HIT) can be used to increase endurance and power output measures between males and females.<br/><br/>Study one aimed to determine if males and females can maintain mean power output (MPO) during repeated sprints when using …

High intensity exercise induced regulation of the microRNA biogenesis pathway
… destabilization – dynamically respond to exercise and regulate the expression of genes involved in mitochondrial biogenesis. However, the regulatory mechanisms governing miRNA expression itself remain poorly understood, particularly in the context of aerobic exercise. This thesis aimed to …

Effects of buffering agents on high-intensity exercise performance and capacity
High-intensity exercise results in hydrogen ion accumulation, which can have a deleterious effect on muscle function, and thus exercise tolerance. Buffering agents are commonly used to enhance exercise performance and capacity. Two such agents, β-alanine and sodium bicarbonate, increase …

The effect of static stretching on lactate removal during recovery from high intensity exercise
… static stretching on lactate removal following high intensity exercise to a passive and a low intensity cycling recovery. Eight male subjects, ages 19-50, with an average VO2{dollar}\sb\max{dollar} of 46.1 {dollar}\pm{dollar} 8.2 ml/kg.min., performed a high intensity cycling protocol followed …

The effect of graded and short-term, high-intensity exercise on expiratory muscle performance
… PeMax, in response to two separate short-term, high-intensity exercise trials. Males (n=7) and females (n=5) not currently in active physical training underwent a VO₂ max test and a constant workload of 90% of VO₂ max. PeMax was measured at rest, immediately post exercise, and at one two and …

The effects of creatine supplementation on performance and metabolism during brief, intermittent, high-intensity exercise
… design. To evaluate the effects of CrS on exercise performance, peak power (PPO) and mean power (MPO) were determined during the 30 s and 6 min RI sprint series. To monitor the metabolic effects of CrS, arterialised venous blood was sampled at rest, immediately after the fifth and tenth …

The Influence of Post-Exercise Feeding on Bone Biomarkers Following an Acute High-Intensity Exercise Bout in Young, Healthy Adults
Exercise and nutrition, specifically dairy products, are interventions that can influence bone. There is limited evidence on the effects of wholefood dairy consumption following an acute exercise bout on bone biomarkers. The objective of this study was to determine whether the consumption of either …

Effects of Pre-exercise Muscle Glycogen Status on Muscle Phosphagens, Sarcoplasmic Reticulum Function, and Performance During Intermittent High Intensity Exercise
… performed two cycling trials, one following a high carbohydrate diet (H-CHO) and the other following a low carbohydrate diet (L-CHO). Trials consisted of repeated 60s maximal effort sprints to fatigue at a workload designed to elicit 125-135% VO<sub>2peak</sub> at 90rpm. Three min of recovery …

Effects of Acute Exercise on Postprandial Lipemia and Postprandial Glycemia
<p>Introduction: Moderate-intensity aerobic exercise has been shown to attenuate the rise in triglycerides in during the postprandial period, however the effects of acute bouts of high-intensity exercise on postprandial lipemia and glycemia have not been explored. The purpose of this study was to …

Mechanistic Insights into the Effects of Exercise on Inflammatory Responses
… response that are altered following long-term exercise in mice. C57/Bl6 mice were randomly assigned into a control group and an exercise group. Various modes of exercise training programs were performed by the exercise group. BMDMs were isolated and were then stimulated with several …

Carnosine metabolism and function in the thoroughbred horse
Thoroughbred horseracing involves high-intensity exercise characterized by the production and accumulation of hydrogen (H<sup>+</sup>) ions within the skeletal muscles. Without a system for maintaining acid-base balance the consequential accumulation of H+ ions within the working muscles would …

Anaerobic performances and anaerobic characteristics of asthmatic children
… the related physiological effects of short-term, high intensity exercise on the asthmatic child. The research incorporated three studies that measured the physiological responses of asthmatic and non-asthmatic children to varied anaerobic stimuli.

Individual differences in affect and vagal tone in response to moderate- and high-intensity interval exercise: A preliminary model
Background. Evidence suggests regular exercise, amongst other healthy lifestyle choices, promotes enhanced quality of life and longevity. However, the majority of adults (>85%) do not meet the requirements suggested by the U.S. Physical Activity Guidelines, thus missing out on potential benefits. …

Autophagy During and Following Dynamic Exercise in Young Adults: Influence of Exercise Intensity
… plays a critical role in the cell’s response to exercise-induced cell stress. Exercise intensity and elevations in tissue temperature are known to modulate autophagic activation, however, the relationship is still unclear. Thus, we investigated the effect of increasing intensities of exercise, as …

Sweating away depression? : the impact of intensive exercise on depression
… of prolonged stress and pain from strenuous exercise, the body produces chemicals called endorphins that help it endure pain. These natural analgesics are presumably only released when the level of pain intensity is at least moderately high. The PANIC/separation distress system is built on …

Ventilatory Mechanics in Endurance Athletes
The lungs were once thought to be over-built for exercise. However, upon further research, endurance athletes have been found to reach their maximum ventilation, demonstrating an insufficiency of the lungs to accommodate the demands of highly demanding endurance sport. This knowledge has inspired …

Pulmonary function and acid-base balance high intensity constant-load exercise
… response of the pulmonary system might limit high intensity exercise in man has received increasing attention over the past few years. However, very few scientific investigations have focused systematically on pulmonary function during high intensity constant-load exercise. Furthermore, many …

Understanding The Pathogenesis of Renal Medullary Carcinoma
… with RMC more frequently participated in high-intensity exercise than matched controls. Using mouse models of SCT, we demonstrated the significant increase of renal hypoxia in the right kidney following high- but not moderate-intensity exercise. We also demonstrated in cell culture studies …

The Influence of Maximal and Submaximal Cyclic Concentric and Eccentric Exercise on Chondrocyte Death and Synovial Fluid Proteins in the Rabbit knee
… but little is known about the effects of exercise loading on synovial fluid (SF) composition and chondrocytes viability. The purpose of this study was to load intact knee joints with two types of controlled maximal muscular contractions (low, and high intensity exercise) and identify …
