Stride Length-Speed Relationship During Body Weight Supported Running, Carmen Chona
Stride Length-Speed Relationship During Body Weight Supported Running, Carmen Chona
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to determine if body weight support influences the stride length-speed relationship. Additionally, the purpose was to determine if impact characteristics of running are influenced by body weight support and speed. Subjects (n=10; 6 female, 4 male) volunteered to participate in this study. All subjects were injury free and were comfortable running on a treadmill for 30 minutes. Subjects ran on a lower body positive (LBPP, Alter-G, G-Trainer) treadmill for 4 conditions of body weight (100, 40, 30 and 20% of body weight) and 4 running speeds (100, 110, 120 and 130% of the preferred …
The Effects Of A Single Bout Of Self-~Myofascial Release On Flexibility And Maximum Voluntary Contraction, Jonathan Robert Garcia
The Effects Of A Single Bout Of Self-~Myofascial Release On Flexibility And Maximum Voluntary Contraction, Jonathan Robert Garcia
UNLV Theses, Dissertations, Professional Papers, and Capstones
Purpose: The purpose of this study was to determine the effect of foam rolling on hamstrings flexibility, isometric and isokinetic torque. Participants: Thirteen female participants (N = 13; age: 28.5 + 6.8 years of age; height: 165.5 + 6.7 cm; mass: 64.2 + 8.4 kg) volunteered to participate in the study.
Methods: Hamstring flexibility was assessed using a sit and reach test; muscle strength was assessed by having participants complete a maximal voluntary isometric contraction (MVIC) of the hamstrings and maximal effort isokinetic knee flexion test using an isokinetic dynamometer. Participants completed these tests prior to any intervention (pre-rolling 1), …
Sex Differences In Human Fatigability: Mechanisms And Insight To Physiological Responses, Sandra K. Hunter
Sex Differences In Human Fatigability: Mechanisms And Insight To Physiological Responses, Sandra K. Hunter
Exercise Science Faculty Research and Publications
Sex-related differences in physiology and anatomy are responsible for profound differences in neuromuscular performance and fatigability between men and women. Women are usually less fatigable than men for similar intensity isometric fatiguing contractions. This sex difference in fatigability, however, is task specific because different neuromuscular sites will be stressed when the requirements of the task are altered, and the stress on these sites can differ for men and women. Task variables that can alter the sex difference in fatigability include the type, intensity and speed of contraction, the muscle group assessed and the environmental conditions. Physiological mechanisms that are responsible …

Examination Of Two Hydration Protocols During Simulated Forced Marching Under Acute Heat Stress, David Alan Cottrill
Examination Of Two Hydration Protocols During Simulated Forced Marching Under Acute Heat Stress, David Alan Cottrill
Theses, Dissertations and Capstones
The purpose of this study was to identify and compare the effects of ingesting either water or 6% solution of carbohydrates, electrolytes, and water on hydration status during simulated military road marching in hot environmental conditions. Five volunteer male subjects completed two 60 minute experimental trials exercising at a high intensity (RER .90-.95) in an improvised environmental chamber (29.7 + or - .18oC, 11.3 + or - 2.13% relative humidity) in full army combat uniform carrying 18.18kg of equipment. Random assignment of either water or solution was completed prior to trial 1, and consumption of the unselected protocol …
