Evaluation of Metabolic Energy Expenditure During Prolonged Steady-State Exercise
Energy consumed during prolonged steady state exercise was partitioned to radiant, convective and evaporative heat and the energy for climbing and walking. Healthy, non-obese subjects, ages 20 to 35 years, were classified as 5 active males, 5 trained males, 5 active females and 5 trained females. …

The Ventilatory Threshold and Maximal Steady-State Exercise in Patients with Coronary Artery Disease
… with onset of lactate accumulation and maximal steady-state exercise (MSS) level. Also, studies have shown the VT is useful in prescribing exercise for cardiac patients in that it gives an exercise intensity at which the patient is metabolically stable. METHODS: The purpose of this study was to …

Ratings of perceived exertion during steady-state exercise using leg-only versus arm-and-leg cycle ergometry
… to believe that perceived effort during exercise is lower with greater active muscle mass (Hagan, et al., 1983; Sargeant & Davies, 1973; Shephard, et al., 1992; Stenberg, et al., 1967), presumably because the effort is distributed to more muscle tissue. The purpose of this investigation …

A comparative analysis of the heart rate-oxygen consumption relationship observed during Bruce protocol graded exercise stress tests and steady-state exercise
… tests were similar to those observed during steady-state exercise. In addition, maximal oxygen consumption and maximal heart rate values obtained during the stress tests were compared to predicted values. The heart rate-oxygen consumption relationship observed during the stress tests was …

Physiological and metabolic responses to constant and variable load cycling performance
… the physiological responses to constant load and steady state exercise are determined. In Section B, the metabolic factors associated with constant and variable load cycling performance are examined.

Metabolic and hormonal responses to altered carbohydrate availability and its effect on fatigue development
… (CHO) availability, achieved primarily by pre-exercise dietary manipulation and antecedent exercise exposure, on interindividual variability in metabolic and hormonal responses to dynamic, steady-state exercise. Further, this thesis examined the impact of altered blood glucose availability on …

Assessment of Peripheral and Central Hemodynamics During Leg Exercise With "Blood Flow Restriction"
“Blood flow restriction” (“BFR”) is a type of exercise training where a pneumatic cuff is applied to the proximal portion of an exercising limb. In “BFR”, cuff inflation to 40% of an individual’s arterial occlusion pressure (AOP; cuff pressure which fully occludes limb arterial flow at rest) is …

The effect of aerobic base training on heart-rate variability and performance in elite youth football players
… activity in the ANS. Research has shown that steady state exercise (60-70% of maximum heart rate) can increase parasympathetic activity in the ANS which would increase HRV (Borghi-Silva et al., 2009). This suggests that the impact on HRV could be used to an athletes’ advantage when trying to …

The role of metabolic rate and substrate utilization in the maintenance of body weight, body composition and insulin sensitivity
… alone results in significant weight loss, exercise-only interventions provide small amounts of weight loss and prevent weight gain, while also improving many of the other variables targeted in obesity treatment. Once achieved however, successful weight-loss maintenance is challenging, with …

THE EFFECTS OF SHOE TYPE ON BIOMECHANICAL AND PHYSIOLOGICAL RESPONSES TO STEPPING AND INCLINED WALKING
… stepping task to determine mean variables during steady state exercise. Results showed that during the lowering phase of the stepping cycle, ankle ROM and ankle and knee moments were significantly greater in hiking shoes than hiking boots, indicating that no compensatory mechanisms of the knee and …

Effects of low-intensity exercise on blood pressure, heart rate, rate-pressure-product and cardiac autonomic function in hypertensive women
The effects of a twelve-week low-intensity exercise conditioning program on blood pressure (BP), heart rate (HR), rate-pressure-product (RPP) and cardiac autonomic function were examined in menopausal and post menopausal women with hypertension. Eligible participants (n=50) were counterbalanced to …

The role of exercise in the treatment of HIV-1 and AIDS
… present study was to examine the role of regular exercise participation in the treatment of HIV-1 and AIDS. Specifically, this study investigated the effects of a 12-week exercise intervention on psychological/emotional, immunological, and physiological training variables. The subjects for this …

Effects of the Angiotensin II Antagonist, Losartan, on Circulo-Respiratory Responses to Submaximal Exercise in Hypertensive Women
… antihypertensive agent Losartan (Lo), on acute exercise performance was assessed in six sedentary, hypertensive women. The purpose, benefits and potential risks of the study were explained to each subject and their informed consent received. In a double blinded crossover design subjects were …

The effects of carbohydrate and protein hydrolysate co-ingestion upon exercise metabolism and cycling performance
… (CHO) supplementation during prolonged exercise are well established. Recently, a number of studies have examined the potential for the inclusion of protein to further augment these efficacious effects. However, observations at present remain equivocal. Furthermore, there is currently a …

Use of Cross-Correlation Analysis to Determine Heart Rate Kinetics During Non-Steady State, Fatiguing Exercise in Collegiate Female Soccer Athletes
… during modeled, quasi-binary, and dynamic exercise using cross-correlation analysis of HR and external work rate. Heart rate and running speed were cross-correlated yielding a cross-correlation function (CCF) and analyzed for its peak (CCFmax) and time delay (CCFlag). Modeled exercise data …

Impact of the menstrual cycle on critical power and submaximal exercise oxygen uptake in recreationally active, eumenorrheic females
… the menstrual cycle on objective and subjective exercise performance are currently unclear. The current study aimed to investigate differences in critical power (CP) and submaximal exercise oxygen uptake (VO2) across three distinct phases of the menstrual cycle (early follicular, late follicular, …

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 …

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 …
