Selection of exercise intensity using perceptual cues during television distraction
The selection of exercise intensity during television distraction was studied in 20 highly-fit males (VO2peak: 63.2 +/- 10.7 ml·kg -1·min-1) between the ages of 28 and 45 years. It was hypothesized that the perception of exercise intensity during cardiovascular exercise would be influenced by …

Multiple sclerosis: Physiological, perceptive and neural responses to exercise intensity
… perceptive and neurological responses to exercise intensity in people with multiple sclerosis (PwMS). The thesis begins with reviews of Multiple Sclerosis (MS) and exercise followed by three main studies. The first study explores the within session and test-retest reliability of motor …

Pacing and opponents: the regulation of exercise intensity during competition
The goal-directed regulation of the exercise intensity over an exercise bout has been shown to be an essential determinant for performance. During their competition, exercisers are required continuously to make decisions about how and when they are going to invest their limited available energy …

The Effect of Choice in Exercise Intensity on Affect and Cognition
… linking positive psychological outcomes with exercise, few have focused on choice as a moderating factor. The research that has examined choice as a moderator yielded mixed results. Currently no research has looked at the impact of choice of exercise intensity on the psychological benefits of …

The Effects of Attentional Focus and Expertise Level on Self-Selected Exercise Intensity
… focus on self-talk versus bodily sensations on exercise intensity chosen by participants and level of enjoyment. One hundred and forty-two undergraduate psychology students ran on a treadmill for 20 minutes on two separate days, one week apart. One day they were asked to focus on their bodily …

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 …

Hormonal and metabolic responses to opioid antagonism during dynamic exercise : influence of exercise intensity
… substrate utilization and hormonal responses to exercise, eight trained cyclists completed two exercise trials at each of two distinct intensity/duration combinations. Briefly, cyclists completed two trials at 70% VO2max for 90 minutes and two trials at 90% VO2max until exhaustion. Trials were …

The Effects of Music Preference and Exercise Intensity on Exercise Enjoyment and Perceived Exertion
… physical and psychological benefits of exercise roughly 50% of people who start an exercise program will have dropped out within six months. Therefore, it is important to examine the determinants of exercise adherence. Past research has shown that enjoyment is an essential factor in …

Exercise Intensity and Performance Aspects of Snow Biking through the Use of a Fat Bike
… study was to quantify, describe, and compare the exercise intensity and performance aspects of riding a fat bike, in a time trial (TT) format, on a natural earthen trail (ET) vs. on a groomed snow trail (ST). Eleven subjects, nine males and two females, participated in this two part study. Heart …

Analysis of exercise intensity and energy expenditure of women participating in the Curves exercise program.
… The purpose of this study was to identify exercise intensity, HR and energy expenditure in a group of women participating in the Curves program. Seventy-eight women (53.6 ± 7.09 yrs, 192.1 ± 30.43 pounds, 43.5 ± 4.52 % fat) performed the Curves workout on two occasions. Results show that …

Effects of Exercise Intensity, Modality and Environment on Gastrointestinal Permeability, Damage and Symptomology in Healthy Males.
It is becoming accepted that exercise increases gastrointestinal (GI) symptomology and permeability potentially effecting performance and recovery. This thesis addresses the issues of how exercise intensity, modality and pattern of exercise will impact upon GI permeability, damage and symptomology …

Exercise and lactational performance : the role of exercise intensity and the timing of an acute exercise bout
… of this study was to determine whether an acute exercise bout in lactating women performed at two different exercise intensities and at different time intervals between exercise and feeding, affects breast milk composition, production and lactate concentration. Eight untrained women, whose …

Determining the Maximal Physiological Steady State in Cycling with Precision: Critical Power Estimations or Self-selected Exercise Intensity?
Giving the inherent limitations of critical power (CP) testing and the demanding maximal lactate steady state (MLSS) protocol, this thesis aimed: i) to compare the power outputs (POs) derived from two methods of estimating CP (i.e., the power-time relationship (CPHYP) and the 3-minute all-out test …

Do self-reported individual differences in preference for and tolerance of exercise intensity predict CrossFit® WOD performance?
… popular, wide-ranging strength and conditioning exercise program. Research has begun to shed light on the exercise intensity-affect-adherence relationship, but this kind of exercise is unique and has yet to be systematically studied. By examining individual difference characteristics (e.g., …

The effects of exercise intensity and cognitive load on acute changes in attention and vigilance in healthy young adults
Many studies have reported acute effects of exercise on cognition, and that exercise intensity is a key factor affecting post-exercise cognition. It appears that the cognitive load associated with exercise may also influence post-exercise cognition, but this has not been quantified. Little …

The adaptive response of humans to exercise: Impact of exercise intensity, fibre-type specific responses and molecular patterns of response
… understanding of the adaptive response to exercise in humans, this dissertation performed a series of studies designed to examine the impact of training intensity and mode on aerobic capacity and performance, fibre-type specific adaptations to training, and individual patterns of response …

The regulation of metabolic gene expression in human skeletal muscle by exercise: the influence of exercise intensity and contraction frequency
… regulator of metabolic gene expression. Acute exercise stimulates a unique set of intracellular signalling cascades resulting in the activation of kinases which can subsequently control muscle metabolism. The signalling pathways involved are activated by alterations in ATP turnover, calcium …

Modulation of exercise-induced gene expression in human skeletal muscle by exercise intensity, training status and short-term endurance training
A single bout of exercise generates a robust, but transient, increase in mRNA abundance for a multitude of genes, which is thought to contribute to the recovery from and adaptation to exercise. Adaptation to exercise training is mediated by the accumulation of pulses of elevated mRNA after …
