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 …
Why Is There Still So Much Confusion About Vo2 Plateau? A Re-Examination Of The Work Of A.V. Hill, Richard Vincent Castle
Why Is There Still So Much Confusion About Vo2 Plateau? A Re-Examination Of The Work Of A.V. Hill, Richard Vincent Castle
Masters Theses
Maximal oxygen uptake (VO2max) is regarded as the gold standard for assessing aerobic fitness. In 1923, Hill et al. proposed that VO2max represents the maximal ability of the body to take in and consume O2 during strenuous exercise. Recently, however, controversy has arisen over the issue of whether a leveling off, or "plateau" in VO2 is necessary to verify attainment of VO2max. Purpose: To compare two different VO2max protocols and determine if both protocols show direct evidence of an upper limit on VO2. Methods: Nine runners (18-35 years old) completed …
