International Journal of Exercise Science

International Journal of Exercise Science 15(3): 1514-1527, 2022. While neuromuscular fatigability has been previously characterized after running and cycling, no study has investigated an ultra-endurance upper body task. In preparation for a world record attempt, three pacing strategies to perform 1980 pull-ups in 6 hrs were compared during independent sessions: fast pace, long recovery (FL), fast pace, multiple short recoveries (FMS), and slow pace, no recovery (SN). Elbow flexion maximal voluntary contraction (MVC) force, grip strength, peripheral fatigue, and biceps brachii electromyography were quantified every 330 pull-ups and during recovery, alongside heart rate, perceived effort, and arm muscle pain.

The Triple Step In Recreational Swing Dancers: A Kinematic Analysis, Meredith D. Wells, Feng Yang

International Journal of Exercise Science

International Journal of Exercise Science 15(1): 1492-1505, 2022. Swing dancing is gaining popularity, yet our biomechanical understanding of swing dance remains poor, creating barriers to the development of training protocols and evaluation of performances. This study aimed to determine whether dancing with or without a partner affects the lower extremity kinematics of the triple step, and if the kinematics differ among the three steps of the dance element. Eight recreational swing dancers completed three sets of rightward triple steps with and without a partner. The angles in the sagittal, frontal and transverse planes were determined for bilateral lower limb joints …

International Journal of Exercise Science

International Journal of Exercise Science 15(1): 1472-1480, 2022. Non-invasive brain stimulation has been prominent in recent neurophysiology research. The use of brain stimulation has not been examined in combination with the focus of attention paradigm, an established motor control tool. Therefore, the purpose of this study was to examine the effects of both brain stimulation and focus of attention on the outcome performance, peak force, lower extremity joint kinematics, and projection angle of a standing long jump. Forty-one participants were assigned to either the brain stimulation group or placebo group via a counterbalance design based on leg length and jump …

Changes In Fitness-Fatness Index Following A Personalized, Community-Based Exercise Program In Physically Inactive Adults: A Randomised Controlled Trial, Abbey M. Jones, Lance C. Dalleck, Ryan M. Weatherwax, Joyce S. Ramos

International Journal of Exercise Science

International Journal of Exercise Science 15(4): 1418-1429, 2022. Fitness-fatness index (FFI) is used to identify those at high risk of developing type 2 diabetes and cardiovascular events. It is measured as the ratio between an individual’s cardiorespiratory fitness (CRF) and waist-to-height ratio. Studies suggest that CRF and waist-to-height ratio are modifiable and can be improved by exercise. However, there is limited evidence surrounding a personalized approach to exercise prescription. This study investigated the impact of a 12-week personalized exercise program on FFI among sedentary individuals. It was hypothesized that the intervention would be effective in improving FFI in this cohort. …

Rehabilitation Sciences Faculty Publications

There is evidence in the literature to suggest that low back pain may change spine–pelvis coordination during activities of daily living. This study aimed to compare the variability of the spine– pelvis coordination during sit-to-stand in people with and without LBP. Ten healthy individuals with a history of LBP and ten individuals without history of LBP participated in this study. Three-dimensional kinematic data of the upper trunk (UT), lower trunk (LT), lower back (LB), and pelvis segments during sit-to-stand and stand-to-sit were recorded using a multi-segmental spine and pelvis models using a motion capture system. The coordination patterns and the …


Incorporating Excess Post-Exercise Oxygen Consumption Into Accelerometer Energy Expenditure Estimation Algorithms, Nicholas Remillard 2022 University of Massachusetts Amherst

Incorporating Excess Post-Exercise Oxygen Consumption Into Accelerometer Energy Expenditure Estimation Algorithms, Nicholas Remillard

Masters Theses

Accelerometers are objective monitors of physical activity (PA) that can be used to estimate energy expenditure (EE). Most accelerometer EE estimation equations are based on steady-state data and do not consider excess post-exercise oxygen consumption (EPOC) after exercise. PURPOSE: To quantify the error in accelerometer EE estimates due to EPOC after varying durations of high-intensity treadmill running. METHODS: Nine young, healthy, recreationally active males participated in three study visits. Visit 1 included a treadmill VO2 peak test to determine the treadmill speed correlating to 80% VO2 peak for visits 2 and 3. Visit 2 included a …

Four Weeks Of Hericium Erinaceus Supplementation Does Not Impact Markers Of Metabolic Flexibility Or Cognition, Corey Grozier, Victor Alves, Lauren Killen, Eric O'Neal, Jeffrey Simpson, Hunter Waldman

International Journal of Exercise Science

International Journal of Exercise Science 15(2): 1366-1380, 2022. Hericium erinaceus (HE), also known as Lion’s Mane mushroom, has been found to enhance cognition and metabolic flexibility in various animal models. To date however, only four studies exist in humans and none have evaluated the effects of HE on markers of metabolic flexibility or cognitive performance. A single-blind, placebo controlled, parallel-longitudinal study was used to determine the effects of HE on markers of metabolic flexibility and cognition. Twenty-four participants completed a graded exercise test on a cycle ergometer to analyze substrate oxidation rates and markers of cardiorespiratory fitness. Additionally, two dual-task …

Faculty Scholarship

LGD-4033, a selective androgen receptor modulator, and MK-677, a growth hormone secretagogue, are becoming increasingly used amongst recreationally-active demographics. However, limited data exist describing their effects on health- and androgen-related biomarkers. The purpose of this case study is to report changes in body composition and biomarkers during and after continued co-administration of LGD-4033 and MK-677. We additionally aimed to examine muscular strength and intramuscular androgen-associated biomarkers relative to non-users. A 25-year-old male ingested LGD-4033 [10 mg] and MK-677 [15 mg] daily for 5 weeks. Blood and body composition metrics were obtained pre-, on-, and post-cycle. One repetition maximum (1RM) leg …
