Topics in Exercise Science and Kinesiology Volume 5: Issue 1, Article 1, 2024. Ingestion of dark chocolate (DC), a dietary source high in flavanols, may increase nitric oxide bioavailability. Elevating blood nitric oxide concentrations may augment metabolic efficiency by reducing the amount of oxygen or energy needed to perform a given task. Utilizing a crossover design, the purpose of this study was to investigate the effect of acute ingestion of DC on running economy (RE). Nineteen recreationally trained females (age: 20±1 years) volunteered for this investigation, with 16 completing all procedures (n = 16). Two-hours before RE assessment, participants consumed …
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 …
Effect Of Racing Flats On Running Economy In Male Adolescent Runners, Paul Hafen
Effect Of Racing Flats On Running Economy In Male Adolescent Runners, Paul Hafen
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to investigate whether running economy differs in racing flats versus standard running shoes in high school cross-country runners. In order to measure running economy the oxygen cost of running (mL O2∙kg-1∙min-1) was measured in 20 male adolescent runners (mean age = 16.25 ± 0.97 years, 5 km best time = 17.52 ± 0.78 min) when running two separate trials at a controlled speed. The speed was determined by estimating treadmill running speed at 85% of each runner's VO2max. Each trial required the participants to run while …
