The Effect Of Tempo On Prone Hamstring Exercise - An Exploration Of Unilateral Bias, Derick A. Anglin Jan 2023

The Effect Of Tempo On Prone Hamstring Exercise - An Exploration Of Unilateral Bias, Derick A. Anglin

Electronic Theses and Dissertations

Hamstring injuries are common muscle-skeletal injuries with a high recurrence rate. While unmodifiable risk factors (e.g., previous injury) vary, recent evidence has questioned the utility of eccentric exercise in preventing hamstring strains. Furthermore, whether eccentric exercise can transfer to sprinting’s kinetic and kinematic requirements is of question. Therefore, this investigation examines exercise tempo (fast vs. slow eccentric phase), movement strategy (bilateral vs. unilateral), and external load characteristics (coupled vs. independent) bias concentric (CON) and eccentric (ECC) biceps femoris (BF) mean electromyography (mEMG). METHODS: Twenty college-aged students aged 18 – 33 (M = 23.4, SD = 3.12 years) with …


The Reliability Of The Navicular Drop Test And Its Transferability To Dynamic Movement, Joshua Krispin Jan 2017

The Reliability Of The Navicular Drop Test And Its Transferability To Dynamic Movement, Joshua Krispin

Electronic Theses and Dissertations

Background: Navicular drop can be defined as the distance the navicular tuberosity moves from a standing weight bearing to a standing neutral position, as the subtalar joint moves from a relaxed position to a neutral position. Navicular drop is an important measurement for clinicians used to describe foot function, pronation, and excessive movement seen in several pathologies. Objective: The purpose of this study is to see if navicular drop is influenced by mode or speed of locomotion, if it is will there be other influences such as the forefoot and heel soft tissue, and will those factors influence those measures. …
