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

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

Cal Poly Humboldt 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 …


Effects Of A Race Timer On The Three Minute All-Out Test For Critical Power, Paul K. Mandell Jan 2019

Effects Of A Race Timer On The Three Minute All-Out Test For Critical Power, Paul K. Mandell

Cal Poly Humboldt theses and projects

Maximal exercise testing is commonly employed by exercise scientists in order to assess an athlete's’ capabilities and inform future training goals and tactics. The Critical Power (CP) concept provides a novel perspective on the physiological capacity of an individual to perform work. The 3 Minute All-Out Test (3MT) for critical power was developed by Vanhatalo, Doust, & Burnley in 2006. Concerns about pacing during the test lead to the development of protocol which blinds participants to time during the test. Twelve healthy active males were recruited to participate in the current study on the effects of a race timer on …
