International Journal of Exercise Science
International Journal of Exercise Science 15(1): 1179-1189, 2022. The biceps femoris (BF) is a double-jointed muscle that performs both hip extension and knee flexion, making it a challenging muscle to train during common resistance training movements. An imbalance between the posterior and anterior chain increases the risk of lower-extremity injury. The purpose of this study was to compare BF proximal (BFprox), BF medial (BFmed), and BF distal (BFdist) peak and mean muscle activation among four hip hinging movements and two knee flexion movements. A secondary variable was gluteus maximus (GMax) muscle activation among the same six movements. Fifteen trained females …

Freely Chosen Cadence Is Increased During Repeated Bouts Of Submaximal Ergometer Pedalling, Andreas Schmidt, Jonas G. Madsen, Magnus K. Hyttel, Ernst A. Hansen
International Journal of Exercise Science
International Journal of Exercise Science 15(1): 1142-1155, 2022. It was investigated whether the phenomenon of repeated bout rate enhancement occurs during submaximal ergometer cycling. Repeated bout rate enhancement is defined as an increase of the freely, or spontaneously, chosen cadence during repeated bouts of pedalling and has previously been reported for finger tapping. This is relevant to study since cadence can affect biomechanical and physiological responses. Recreationally active individuals (n=27) performed five consecutive 5-min bouts of cycling at 100 W using freely chosen cadence. All bouts were separated by 10-min rest. Cadence, pedal force profile characteristics, heart rate, …

Investigating The Short-Term And Long-Term Impact Of Covid-19 On Cardiovascular Health, Damsara Nandadeva
Kinesiology Dissertations - Archive
Recent data indicates that the risk of developing cardiovascular disease (CVD) is augmented following coronavirus disease 2019 (COVID-19). Moreover, emerging data indicates that almost 50% of individuals who had COVID-19 experience persisting symptoms which are often debilitating, beyond the acute phase of the illness. This condition that is given the diagnosis post-acute sequalae of COVID-19 (PASC), also appears to be associated with cardiovascular complications. However, it is unclear what factors contribute to CVD risk following COVID-19 and PASC. Accordingly, the aim of this dissertation was to investigate potential factors that may contribute to adverse cardiovascular outcomes following COVID-19 with a …

Reducing Disparities In Physical Activity And Early Child Development: A Systematic And Observational Approach, Samantha Moss
Kinesiology Dissertations - Archive
Engaging in adequate (180 minutes per day) physical activity (PA) is an important component in positioning a young child towards optimal health. PA engagement has been linked to improved cardiovascular health, developmental outcomes (i.e., motor, social, and cognitive development), and weight status. Even with the known benefits PA posits, many young children do not receive enough PA during their day. More specifically, children that are of low socio-economic status (SES) pose a greater risk for inactivity, excessive sedentary behavior, and developmental delays. Knowing these disparities exist, even starting in the early childhood years, children’s PA and development remain complex. Using …

Elevated Cardiovascular Disease Risk In Black Females: The Impact Of Social Determinants Of Health And Novel Preventive Strategies, Zachary Thomas Martin
Kinesiology Dissertations - Archive
Among females in the United States, Black females suffer from the highest rates of hypertension, coronary artery disease, stroke, and total cardiovascular disease (CVD) mortality. Blunted peripheral and cerebral vascular function contribute to the development of CVD and are predictive of CVD risk. Although the causes of disparate cardiovascular health among Black females are multifactorial, upstream contributors such as psychosocial stress attributable to structural and interpersonal racism are likely critical. However, the societal changes required to dismantle structural racism and thus improve health outcomes may take decades to implement. Therefore, in addition to such policy changes, populations who face health …

Previous studies have shown that individuals with various physical, sensory and neuromuscular impairments are at higher risks of falls. Individuals with unilateral transtibial amputation (UTTA) suffered from all these impairments, and tripping not surprisingly caused a considerable number of falls in this population. To study falls, researchers have to put participants in a well-protected environment and reproduce tripping fall scenarios. Furthermore, the perturbation delivery needs to be precise in terms of temporo-spatial timing. These features would ensure the quality of responses elicited and reproducibility of the results. Thus, in Chapter 2, we developed a treadmill-based perturbation delivery protocol and confirmed …
