Changes In Vertical Reaction Force During Treadmill High-Intensity Interval Training, Jared Moore, Garry Cai, George Salem
Changes In Vertical Reaction Force During Treadmill High-Intensity Interval Training, Jared Moore, Garry Cai, George Salem
International Journal of Exercise Science: Conference Proceedings
High-intensity interval training (HIIT) has become a popular form of exercise due to its low time burden and easily customized protocols. To date, there has been no investigation into how lower extremity loading (ie. GRF) changes over time during a HIIT protocol. Examining this load variability can help inform protocol development for different populations. PURPOSE: The purpose of this pilot study was to examine how the vertical reaction force (vRF) changes during a HIIT running protocol in order to elucidate how working at high intensity for 4min periods can influence subsequent lower extremity loading. METHODS: Three participants (26±3y) …
A Case Study Comparison Of Lower Extremity Kinematics In Medial Tibial Stress Syndrome, Amanda Hernandez, Patricia Vanoosbree, Kristyne Wiegand
A Case Study Comparison Of Lower Extremity Kinematics In Medial Tibial Stress Syndrome, Amanda Hernandez, Patricia Vanoosbree, Kristyne Wiegand
International Journal of Exercise Science: Conference Proceedings
Medial tibial stress syndrome (MTSS) affects up to 35% of runners. Chronic MTSS can negatively affect performance or lead to a cessation of activity. Though biomechanical variables such as hip internal rotation, tibial abduction, and rearfoot eversion are considered potential risk factors for MTSS, the research is equivocal. PURPOSE: Therefore, the purpose of this case analysis is to compare lower extremity kinematics of a D3 middle-distance runner with chronic MTSS vs. a matched uninjured runner. METHODS: This case study consists of two female middle-distance runners. Participant one (19 y.o., 1.73 m, 70.3 kg) experienced intermittent MTSS for 4 years. …

Biomechanical Changes In Running Post-Transition In A Triathlon, Luke Vankeersbilck, Travis Peterson Phd
International Journal of Exercise Science: Conference Proceedings
Triathletes often complain about lower limb discomfort when running after cycling (Quigley, 1996). Several studies have found differences in muscle activation (Chapman, 2009), kinematics (Rendos et al., 2013), and kinetic cost (Millet, 2001) during the transition run. These differences were also found to be more severe in less experienced triathletes (Chapman, 2008). PURPOSE: This study aimed to determine the kinetic differences between baseline and transition runs of inexperienced triathletes. METHODS: Twelve novice triathletes age: 29.4 ± 12.15 y, mass: 71.2 ± 10.3 kg, weekly running mileage: 24.4 ± 16.7 mi/week volunteered to participate. Athletes completed a 20 min …

International Journal of Exercise Science: Conference Proceedings
Commercially available fitness watches provide recreational athletes insight into aerobic fitness. The Garmin fēnix. 6S (GF) is a recently released multisport watch that provides estimations related to aerobic and endurance performance, including maximal oxygen consumption (VO2max). VO2max is an important physiological metric to determine aerobic capacity, structure training, and anticipate race performance. PURPOSE: Therefore, the purpose of this study was to determine the validity and accuracy of the GF’s prediction of VO2max in the general population compared to lab-based measurements. METHODS: 20 healthy participants (9 male, 11 female, 24 土 5.4 years, 30.45 土 21.79 km run/wk) participated in two …
