The Relationship Between Gluteus Maximus Activation And Running Kinematics In Recreational Distance Runners, Ricardo Sanchez

Cal Poly Humboldt theses and projects

Within the running community, there are strategies that a trainer will utilize to improve the performance of an athlete. One of these strategies suggests that an increase in activation of the Gluteus Maximus (GM) muscle will result in an increase in the efficiency of runners. The primary purpose of this study was to examine the relationship between GM activation and running kinematics.

Methods: Three female and seven male recreational runners (27±8 yrs) from California Polytechnic State University, Humboldt and the local community. A Pearson product-correlation was used to determine the strength of the relationship between Gluteus Maximus activation and kinematic …

The Independence Effects Of Gravitational And Inertial Forces On Gait Transitions In Humans, Nathan Frakes

Cal Poly Humboldt theses and projects

The Dynamic Similarity hypothesis suggests gravitational and inertial forces plays a role in determining preferred transition speed (PTS) for walk to run transitions (WRT) and run to walk transitions (RWT), and that humans prefer to transition gait when the ratio of inertial force (IF) to gravitational force (GF) (i.e. Froude #) is ~0.5. Purpose: To investigate the effect of gravitational and inertial forces on PTS, Froude # (Fr) and kinematics for both WRT and RWT. Methods: Twelve healthy adults (9 M, 3 F) performed WRT and RWT trials on a treadmill across seven combinations of altered body weight (BW) and …

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

Cal Poly Humboldt 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 1-3 were HIIT running sessions, and Protocol 4 was …

The Effect Of Postural Alterations On Metabolic Cost In Running On Incline Slopes, Nikaela K. Hemminger

Cal Poly Humboldt theses and projects

In spite of an intuitive relationship between running technique and performance, the influence of specific techniques on metabolic cost remains unclear. While recent studies suggest that postural lean affects metabolic cost during level ground running, little information exists regarding the influence of postural lean on the metabolic cost of running on an incline slope. Purpose: This study sought to investigate the effect of postural lean on metabolic cost, kinematics, and muscle activation of running across a range of incline slopes. Methods: Sixteen healthy adult runners (21±2 years, 8M/8F) of different competitive standards participated in twelve running trials on a motorized …
