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 ...


Trunk, Hip And Knee Motions During A Step-Down Test And Running In Patellofemoral Pain Individuals, Katie Olinger Jan 2019

Trunk, Hip And Knee Motions During A Step-Down Test And Running In Patellofemoral Pain Individuals, Katie Olinger

WWU Graduate School Collection

Context: A common knee injury in runners is patellofemoral femoral pain syndrome (PFPS). The step-down test (SDT) is used to analyze lower extremity motions in runners with PFPS because kinematics are similar for the SDT and running. Individuals with PFPS often experience altered kinematics when compared to healthy. However, there are no known studies that examine the relationship in kinematics between the SDT and running.

Objective: Examine the relationship between lower extremity kinematics of the knee, hip and trunk in runners with PFPS and healthy controls, during the midstance of running and during a SDT.

Patients or Other Participants: Sixteen ...


Differences In Running Mechanics And Tibial Plateau Dimensions Between Overweight/Obese And Healthy Weight Children, Claire Sylvestre Jan 2019

Differences In Running Mechanics And Tibial Plateau Dimensions Between Overweight/Obese And Healthy Weight Children, Claire Sylvestre

Electronic Theses and Dissertations

INTRODUCTION: Overweight and obese (OW/OB) children display increased knee joint loading during running, which may lead to excessive frontal plane motion and moments at the knee joints. The relationship between tibial plateau dimensions and knee vertical loading may explain the loading related injuries OW/OB children experience.
PURPOSE: Compare knee mechanics during running and tibial plateau dimensions between healthy weight (HW) and OW/OB children.
METHODS: Ten HW children and ten OW/OB children aged 9-12 participated in the study. Kinematic and kinetic data were captured as participants ran across a force platform at 3.5m/s. Tibial plateau ...
