Cycling Versus Treadmill Potentiation Effects Following High-Intensity Interval Training, Mark Martinez, Juliet Moore, Kathryn Havens, George Salem
Cycling Versus Treadmill Potentiation Effects Following High-Intensity Interval Training, Mark Martinez, Juliet Moore, Kathryn Havens, George Salem
International Journal of Exercise Science: Conference Proceedings
High-intensity interval training (HIIT) has emerged as a popular form of exercise, with intermittent bouts of higher and lower intensity cycles. Not well understood to date is the influence of HIIT exercise modality (e.g., cycling vs treadmill running) on measures of jump performance. A generally accepted metric for assessing performance and overall athleticism involves performing a countermovement jump (CMJ). Furthermore, heavy exercise has been shown to improve muscle performance using post-activation potentiation. Purpose: This study compared the effects of HIIT bouts of cycling vs treadmill running on CMJ concentric impulse, peak takeoff force, and jump height. Methods: Eleven young, …
The Inflammatory Response To Different Hiit Modalities, John G. Wallace Iii, Jared Moore, E. Todd Schroeder
The Inflammatory Response To Different Hiit Modalities, John G. Wallace Iii, Jared Moore, E. Todd Schroeder
International Journal of Exercise Science: Conference Proceedings
Pro-inflammatory and anti-inflammatory cytokines have been documented to change in response to long-duration, aerobic exercise. Little work has been performed in high-intensity interval training (HIIT). Furthermore, it has yet to be elucidated whether the modality of HIIT affects this inflammatory response. PURPOSE: The purpose of this study was to investigate the changes in IL-8 and IL-10 cytokine concentrations pre-post and post-1hr following HIIT protocols using two different exercise modalities, treadmill running (TM) and stationary cycling (CE). METHODS: Eight young, healthy, recreationally active volunteers (1 female, 7 males; 25.50 ± 3.25 years) completed a 4x4 HIIT protocol (4-minute 85-95% …
Peak Power Changes During A Countermovement Jump Following Treadmill And Cycling High-Intensity Interval Training, Michael G. Maregne, Juliet Moore, E Todd Schroeder
Peak Power Changes During A Countermovement Jump Following Treadmill And Cycling High-Intensity Interval Training, Michael G. Maregne, Juliet Moore, E Todd Schroeder
International Journal of Exercise Science: Conference Proceedings
Within activities involving jumping, peak power can be a significant factor to consider when assessing an athlete’s overall physical performance. By investigating different modalities of exercise, it is possible to discover potential benefits or flaws in certain workout regimens that may influence jump performance. In turn, this could influence how physical trainers, athletes, and recreationally active people approach their exercise routine to maximize performance. PURPOSE: The purpose of this study was to investigate the changes in peak jump power during a countermovement jump (CMJ) immediately following and 1-hour post high-intensity interval training (HIIT) using high-impact (running) and low-impact (cycling) …
C-Reactive Protein Changes Following Treadmill And Cycling High-Intensity Interval Training, Juliet Moore, George Salem
C-Reactive Protein Changes Following Treadmill And Cycling High-Intensity Interval Training, Juliet Moore, George Salem
International Journal of Exercise Science: Conference Proceedings
ABSTRACT: The acute inflammatory response to exercise has been well-studied in long duration activities such as marathons and triathlons; however, little work has been done investigating this response in high-intensity interval training (HIIT), which is characterized by intermittent bouts of higher and lower intensity cycles. PURPOSE: The purpose of this study was to investigate the changes in C-reactive protein (CRP) immediately following and 1-hour post HIIT protocols using two different exercise modalities, treadmill running and stationary cycling. METHODS: Eight young, healthy, recreationally active volunteers (1 female, 7 males; 25.50 ± 3.25 years) completed a 4x4 HIIT protocol …
Lower Extremity Loading And Subsequent Muscle Soreness Following High-Intensity Interval Training Protocols: A Pilot Study, Jared Moore, Noah Ogata, George Salem
Lower Extremity Loading And Subsequent Muscle Soreness Following High-Intensity Interval Training Protocols: A Pilot Study, Jared Moore, Noah Ogata, George Salem
International Journal of Exercise Science: Conference Proceedings
High-intensity interval training (HIIT) is a popular form of exercise that is being performed by the general population as well as athletes. There is little work into how the lower extremity loading within HIIT protocols differs among various exercise modalities and the effects these differences may have on resulting muscle soreness. PURPOSE: The purpose of this pilot study was to characterize lower extremity vertical reaction forces (vRF) during treadmill running and cycling HIIT protocols in young, healthy adults and to explore the relations of the vRF with delayed onset muscle soreness (DOMS). METHODS: Participants completed a heart rate …
Recovery Methodologies And High Intensity Interval Training, Blake W. Johnson, Malcolm T. Whitehead
Recovery Methodologies And High Intensity Interval Training, Blake W. Johnson, Malcolm T. Whitehead
International Journal of Exercise Science: Conference Proceedings
As the implementation of high intensity interval training (HIIT) continues to grow among a variety of exercisers, as such, its optimization within a training program must be considered. As with any mode of exercise this necessitates adequate recovery to elicit optimal adaptation and understanding day-to-day recovery from HIIT will permit the greatest benefits for those who desire specific the outcomes from this training. PURPOSE: The purpose of this study was to determine day-to-day recovery from Tabata bodyweight HIIT exercise using different recovery assessment methodologies across 24- and 48-hour time intervals. METHODS: Participants (23.2 ± 3.1 years old, 163.1 ± 19.9 …
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) …

The Effects Of Multiple Bouts Of Tabata On Post-Exercise Metabolism: A Pilot Analysis, Blake W. Johnson, Alexander Alvara, James R. Rowe Jr
International Journal of Exercise Science: Conference Proceedings
PURPOSE: Compare the resting metabolic rate (RMR) following: 1) no exercise (REST), 2) completion of 1 bout of TABATA (1-BOUT), 3) completion of 2 bouts of TABATA (2-BOUT), and 4) completion of 10 bouts of TABATA (10-BOUT). METHODS: Recreationally active individuals (n = 5; 1F, 4M; age = 23.4 ± 1.9 yrs; body mass = 72. 7.2 ± 16.9 kg; body fat% = 28.7 ± 4.9) performed each of the 4 protocols on separate days with at least 7 days in between protocols. Rest consisted of not exercising on the day of the assessment. 1-BOUT consisted of performing a …
Sex Difference In Cardiorespiratory Stress From High-Intensity Interval Exercise, Paolo Miguel Salvador, Mauricio Martinez, Joaquin Gonzales, Eric Rivas
Sex Difference In Cardiorespiratory Stress From High-Intensity Interval Exercise, Paolo Miguel Salvador, Mauricio Martinez, Joaquin Gonzales, Eric Rivas
International Journal of Exercise Science: Conference Proceedings
High-intensity interval exercise is time efficient and has similar cardiorespiratory health benefits as moderate-intensity continuous exercise. However, the prescription of high-intensity exercise may differ between men and women due to sex differences in cardiovascular function. PURPOSE: Therefore, the objective of this study was to examine whether sex differences exist for absolute and relative oxygen uptake (VO2) and heart rate (HR) when exercise was performed at a percentage of maximal cycling work rate measured in watts (Wmax). METHODS: We recruited 8 active college-aged participants (5 men, 3 women). Participants completed an incremental maximal exercise test on a …
