An investigation of RPE-heart rate and the RPE-lactate relationships in elite athletes
This thesis investigated the relationship of ratings of perceived exertion (RPE) with heart rate (HR) and blood lactate (La) that involved four studies. The first study concerned comparing RPE relationships with elite swimmers during exercise tests performed during in-season (IS) and off-season …

The relationship between ratings of perceived exertion, training load, and types of deliberate practice in ice hockey training
Ratings of perceived exertion (RPE) are used in team sport settings to measure the perceived exercise intensity of training. Coaches may use measures of RPE as a method to monitor training load to ensure athletes are being sufficiently challenged without overtraining. However, limited published …

Comparison of heart rates between deep water running, treadmill running, and cycling
… running (TR), cycling, and DWR at 60% and 75% of MaxVO2 were different. Ratings of perceived exertion (RPE) between runners and swimmers during TR and DWR were also compared. Analysis of the data showed that runners, at both intensities, had no difference in HR between TR, DWR, and cycling. At …

Factors affecting perceived exertion and task duration during intermittent isometric fatiguing exercise and their implications for rehabilitation following knee surgery
… self-perception is integral to the regulation of exercise and production of an optimal performance. This concept has not been examined in an anterior cruciate ligament (ACL) reconstructed population where the consequences of injury and surgery may provide a substantive perturbation to …

Determination of the physiological responses of female fire fighters while working in the heat
This study determined the physiological responses of female fire fighters to two similar bouts of work in the heat. Peak heart rates (HR), peak oxygen consumption (VO2), peak rectal temperatures (Trec), peak mean skin temperature (MST), and ratings of perceived exertion (RPE) were compared between …

Cardiorespiratory responses to altered rider position with conventional and aerodynamic handlebars
… The positions were determined by the position of the hands on the handlebars and the posture of the upper body: upright (UP), and drop position (DP) with conventional racing handlebars, and an aerodynamic tuck (AT) using Scott DH time-trial handlebars. Ten well-trained (mean V02max=60.7 ± 3.63 …

Investigating the Relationship Between Objective and Subjective Measures of Physical Demand During Passive Exoskeleton Use
… exoskeletons hold promise in reducing the risk of work-related musculoskeletal disorders, however further research is essential before widespread adoption can occur. This study explores the feasibility of using subjective measures of physical demand in place of costly and less practical …

Effects of Two Backpack Weight Distributions on Perceptual and Physiological Measures During Walking
… Research has not however examined effects of backpack weight distribution on subjective measures of intensity and comfort. Heart rate (HR) and overall and differentiated Ratings of Perceived Exertion (RPE) were examined during simulated backpacking with differentially weighted backpacks. …

The Physiological Effects of Therapy Dogs During Exercise for Sedentary Adults
… pressure (BP) responses during various types of stressors due to an increase in oxytocin (OT) and decrease in cortisol (CL) production. These hormonal changes have also been shown to enhance exercise performance. <strong>Purpose:</strong> This study aimed to determine if physiological …

The Perceived Demands of CrossFit
<p>Rhabdomyolysis is the breakdown of muscle tissue causing myoglobin, creatine kinase, and other intracellular proteins and electrolytes to leak into circulation, disrupting cell homeostasis. Exertional rhabdomyolysis (ER) occurs after extremely rigorous physical training that could include high …

NEUROMUSCULAR ELECTRICAL STIMULATION IN COMPARISON TO HEAT THERAPY AS A MODALITY AFTER EXERCISE-INDUCED MUSCLE FATIGUE
… return to exercise. However, the effectiveness of different recovery modalities remains unclear. The purpose of the study is to evaluate the efficacy of neuromuscular electrical stimulation (NMES) and heat therapy (HT) as recovery modalities after inducing fatigue with maximal exercise in active …

Ice Slurry and Cold Drink Reduces Exercise Induced Physiological Strain in the Heat
Purpose: To determine the effects of an ice slurry beverage on heat strain and thermoregulatory responses during prolonged exercise in the heat. Methods: Twenty males consumed slurry (ICE, -1.4 ± 0.2 °C), cold drink (COLD, -0.7 ± 0.2 °C), or room temperature drink (RT, 21.5 ± 1.0 °C), while walking …

The effects of carbohydrate supplementation on mood states of bodybuilders consuming a low energy diet
Many bodybuilders attempt to lose large amounts of weight in short periods of time through the use of low energy diets. Research suggests that consumption of a low energy, low carbohydrate diet may negatively affect mood states. Further research suggests that carbohydrate consumption can positively …

Effects of chronic suboptimal energy intake on constant-load exercise in young women
The physiologic and metabolic effects of chronic consumption of energy below recommended levels on constant-load exercise was studied in women age 19-24 years. Ten controls (average caloric intake ~ 35 kcal/kg body weight) and 10 subjects with suboptimal energy intake (average caloric intake - 25 …

The effects of amlodipine on exercise performance in mild to moderate essential hypertensives
The effect of the long acting dihydropyridine calcium channel antagonist, amlodipine, on the exercise performance of hypertensive patients is not known. The aim of this study was to determine the effects of amlodipine on maximal (MAX), prolonged submaximal (PSX) and on skeletal muscle function …

Variability of Practice and Strength Training Periodization: When Theories Collide
<p>The primary purpose of this study was to examine whether variability of practice enhances neuromuscular adaptations when compared to traditional strength training. The secondary purpose was to investigate whether there was a difference in perception of exertion between the two strength programs. …

Ratings of perceived exertion during steady-state exercise using leg-only versus arm-and-leg cycle ergometry
… has led many investigators 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 …
