Differences In Strike Index Between Treadmill And Aquatic Treadmill Running In Experienced Distance Runners, James Paul Hoover Jr. May 2014

Differences In Strike Index Between Treadmill And Aquatic Treadmill Running In Experienced Distance Runners, James Paul Hoover Jr.

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Strike index (SI) quantifies how one’s foot contacts the ground at the beginning of the stance phase of gait. SI is reported as a percentage of the total foot length, with lower percentages indicating a more posterior point of contact, while greater percentages indicate a more anterior point of contact along the foot. Differences in SI may be related to running-related injuries, such that experienced distance runners who are rearfoot (posterior) strikers may have approximately twice the rate of repetitive stress injuries than forefoot (anterior) strikers. Previous research has shown that forefoot strikers, as opposed to rearfoot strikers, produce lower …


Metabolic-Cost Comparison Of Running On An Aquatic Treadmill With Water-Jets And Land Treadmill With Incline, Ryan R. Porter May 2012

Metabolic-Cost Comparison Of Running On An Aquatic Treadmill With Water-Jets And Land Treadmill With Incline, Ryan R. Porter

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose: This study investigated whether running on a land treadmill (TM) at specific inclines corresponded to an equivalent metabolic cost (MC, oxygen consumption, VO2) using water-jets on an aquatic treadmill (ATM) at equivalent running speeds. Methods: Sixteen participants completed two trials on separate days on a TM and ATM. For each trial subjects performed eighteen, 3-4 min submaximal runs at three self selected speeds (slow, medium, and fast) with either water-jet resistances of 0-100% of maximum jet flow capacity in 20% increments during ATM or inclines of 0-10% in 2% increments during TM. Trials were separated by at least 48 …
