The Effect Of Manipulating Vertical Motion On Running Economy, Claire Copriviza Jan 2019

The Effect Of Manipulating Vertical Motion On Running Economy, Claire Copriviza

Theses and projects

While several biomechanical factors have been identified as key determinants of running economy (i.e. metabolic cost), the influence of individual mechanical factors such as center of mass vertical motion (ΔCoMz) remains unclear. The purpose of this study was to determine how manipulating ΔCoMz effects running economy. Twelve runners used a visual biofeedback system to control their ΔCoMz during running as we measured the metabolic, kinematic, and muscle activation responses to the different levels of ΔCoMz. Running economy was strongly correlated to ΔCoMz and was optimized at an intermediate center of mass vertical motion of ...


The Effect Of Interval Intensity On Time To Exhaustion During High Intensity Interval Training (Hiit) Running In Recreational Male Runners, Andrew M. Hahn Jan 2019

The Effect Of Interval Intensity On Time To Exhaustion During High Intensity Interval Training (Hiit) Running In Recreational Male Runners, Andrew M. Hahn

Theses and projects

High Intensity Interval Training (HIIT) has become extremely popular in recent years, however, current HIIT prescriptions lack guidelines regarding interval intensities and associated margins. The purpose of this study is to investigate Run Time to Exhaustion (Te) and provide insight regarding HIIT intensities for future aerobic exercise programming. Ten healthy adult male recreational runners (Age=22.9 ± 2.5 yr., Ht=1.72 ± 0.1m, BM=74.1 ± 7.4 kg) measured maximal oxygen consumption (VO2max) (52.4 ± 6.1ml/kg/min) with a graded exercise test (GXT). Running speed was determined using ACSM running equation for exercise metabolism. Protocols ...
