Subcutaneous Adipose Tissue Thickness Changes Cooling Time During Cryotherapy, Jeffrey W. Otte

All-Inclusive List of Electronic Theses and Dissertations

Context: Cryotherapy is often applied using a standard treatment time. Use of a standard treatment time fails to consider the insulating effect subculaneous adipose tissue has during cooling of underlying muscle. If differences in adipose lissuc thickness alter I he effects of cryotherapy, then a standard application time may not produce a slamlard clTcct for all patients. Objective: The purpose of this study was to examine the effects of subcutaneous adipose tissue on cooling time during cryothcrapy. Design: A 1 x 4 factorial design was used in this study. The independent variable was skin-fold thickness, 0-10mm, 1 l-20mm, 2 l-30mm, …

A doubly labelled tracer molecule of glucose, [6,6^-2HJglucose, has been used to measure the rate of glucose appearance in blood due to endogenous glucose production (by the liver and kidneysj.^l,2 Considered 'non-recirculating', this tracer generally provides a realistic estimate of glucose kinetics.^2,3 Used as a dual tracer in conjunction with [l-¹³C]glucose, the extent of glucose recycling can be quantitated.^2-4 but the extent of possible recirculation of a single deuterium atom on newly formed glucose must then be considered.

Fine-Tuning The Exercise Formula, David Swain

Rehabilitation Sciences Faculty Publications

(First paragraph) One hundred years ago, our forebears consumed more calories than we do today, yet they were leaner. Labor-saving devices were a rarity, and so in everyday life most people worked very hard physically. Obesity was present, of course, but afflicted only a small fraction of the population. We are not as fortunate today.

Creatine Supplementation Differentially Affects Maximal Isometric Strength And Time To Fatigue In Large And Small Muscle Groups, William J. Vincent, Steven F. Loy, Richard L. Urbanski, Ben B. Yaspelkis

Faculty Publications

Ten physically active, untrained, college-aged males (26.4 ± 5.8 years old) received creatine (CR. 5 g creatine monohydrate + 3 g dextrose) and placebo (PLA, 7 g dextrose) supplementation four times per day for 5 days in a doubleblind, randomized, balanced, crossover design. Performance was assessed during maximal and three repeated submaximal bouts of isometric knee extension and handgrip exercise. CR supplementation significantly increased (p < .05) maximal isometric strength during knee extension but not during handgrip exercise. CR supplementation increased time to fatigue during each of the three bouts of submaximal knee extension and handgrip exercise when compared to the PLA trials. These findings suggest that CR supplementation can increase maximal strength and time to fatigue during isometric exercise. However, the improvements in maximal isometric strength following CR supplementation appear to be restricted to movements performed with a large muscle mass.

A Comparison Of Measures In Physical Fitness And Biological Maturity Between Female Gymnasts And Females Not Involved In Organized Sport, Cara Kokenes

Masters Theses

The purpose of this study was to investigate differences in physical fitness and biological development between two groups of twelve year old females. One group consisted of idividuals who had been involved in competitive sport for at least two years while the other group was not involved in organized sport. Two groups of 20 subjects were examined in terms of height, weight, flexibility, strength, body composition, maturation, eating attitudes, and cardiorespiratory endurance. The results indicated that the gymnasts were significantly (p<.05) shorter, lighter, stronger in regard to left hand grip strength, lower in percent body fat, less biologically mature, and had greater cardiorespiratory fitness than the non-gymnasts. No significant differences were observed in right hand grip strength or eating attitudes. It was concluded that maturation level as well as gymnastic training played a major role in influencing values obtained through measurements of physical fitness.

Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman

Theses : Honours

Investigations into the mediators of effort sensation have indicated that central mechanisms related to corollary discharges may be responsible for an increased sense of effort during fatiguing isometric exercise. The role for central mediators for sense of effort have been objectively demonstrated through use of contralateral limb matching tasks. Subjects diagnosed with chronic fatigue syndrome (CFS) often report prevalent fatigue associated with a greater sense of effort when involved in exercise. This study employed a fatiguing contralateral limb-matching task in order to determine if CFS subjects (n == 6) experienced an altered sense of effort associated with the task when …
