Forearm Vascular Responses To Rhythmic Handgrip Exercise In Young Healthy Hispanic Men, Randy Liu, Ruby A. Nyarko, Justo Perez, Ashlesha D. Dalve, Tyler Van Wagoner, Crystal Appiah, Jasdeep Kaur

International Journal of Exercise Science: Conference Proceedings

Hispanic American (HA) men have higher prevalence of Type 2 Diabetes (T2D) when compared to Caucasian American (CA) men (15.3% vs 10.8%). Impaired vascular function is a hallmark of T2D, increasing the risk of cardiovascular morbidity and mortality in this clinical population. However, vascular function in the Hispanic population has not been investigated thoroughly. To date, only two studies have examined the resting flow mediated dilation (FMD) and found a higher FMD in young, healthy, HA adults. Whether exercise-induced reactive hyperemia is preserved in HA adults remains unknown. PURPOSE: We tested the hypothesis that young, healthy HA men would …

Role Of Ghrelin Receptor In Sarcopenia: Involvement Of Redox Signaling And Rankl., Mariam A. Othman, Joo Hyun Kim, Khaled Moustfa, John Lawler Feb 2023

Role Of Ghrelin Receptor In Sarcopenia: Involvement Of Redox Signaling And Rankl., Mariam A. Othman, Joo Hyun Kim, Khaled Moustfa, John Lawler

International Journal of Exercise Science: Conference Proceedings

Sarcopenia is aging-induced debilitating loss of skeletal muscle strength and function. Evidence from aging research suggests an integration of disrupted mechanotransduction and oxidative stress elevation that leads to muscle atrophy. Ghrelin is a 28 amino acid peptide hormone circulating in both acylated (AG) and unacylated (UAG) forms that acts as a nutrient sensor and metabolic regulator. Acylated ghrelin then binds to the growth hormone secretagogue receptor (GHS-R) or the “ghrelin receptor.” Emerging evidence indicates that GHS-R knockout may hold greater promise in protecting against sarcopenia and fasting-induced atrophy (Wu 2020, Sun 2020). Furthermore, ghrelin can promote the elevation of nNOS, …

The Rankl And Nox2 Signaling In The Duchenne Muscular Dystrophy Models Of Skeletal Muscle, Joo Hyun Kim, Mariam Othman, Khaled Moustafa, John Michael Lawler Feb 2023

The Rankl And Nox2 Signaling In The Duchenne Muscular Dystrophy Models Of Skeletal Muscle, Joo Hyun Kim, Mariam Othman, Khaled Moustafa, John Michael Lawler

International Journal of Exercise Science: Conference Proceedings

There is a severe sort of muscle disorder and dysfunction caused by a mutation of the dystrophin gene which is called Duchenne muscular dystrophy (DMD). The establishment of pathology in the limbs, respiratory systems, and hearts of DMD patients is the awareness of the main point for the inflammation and elevation of oxidative stress. NADPH oxidase-2 (Nox2) produces reactive oxygen species in response to skeletal muscle contractions. Recent studies show that various myopathy indicated the key stress response proteins which can modulate Nox2. The TRAF 6 and RANKL lead to Nox2 complex migration and construction. An increase of pro-inflammatory proteins …

Aortic Wave Reflection Following Maximal Exercise In Healthy Young Adults, Keng-Yu Chang, Zhaoli Liu, Chueh-Lung Hwang Feb 2023

Aortic Wave Reflection Following Maximal Exercise In Healthy Young Adults, Keng-Yu Chang, Zhaoli Liu, Chueh-Lung Hwang

International Journal of Exercise Science: Conference Proceedings

Increased magnitude and early return of aortic wave reflection decrease coronary perfusion during diastole and augment systolic blood pressure (SBP). Exaggerated SBP in responses to maximal exercise is an indicator of future cardiovascular disease. Several studies investigated aortic wave reflection in response to maximal exercise. However, most of these studies did not provide a comprehensive assessment of wave reflection, including the forward and backward components of the pressure waves. The former are generated by ventricular contraction and the latter are the function of forward waves and waves reflected from the periphery. PURPOSE: This study was to investigate aortic wave …

Stand More, Sit Less, For Better Metabolic Health, Jehu N. Apaflo Feb 2023

Stand More, Sit Less, For Better Metabolic Health, Jehu N. Apaflo

International Journal of Exercise Science: Conference Proceedings

Sedentary behaviors are associated with metabolic risks such as weight gain, high adiposity, and abdominal/visceral fat deposition. The American College of Sports Medicine recommends a minimum of 150 mins per week of moderate to vigorous physical activity for health benefits. Adherence, however, is poor due to the prolonged sitting hours required for most modern jobs and the excessive television viewing habits. Emerging studies show that interrupting long sitting hours with intermitted breaks of light activities attenuates the pernicious effects of sedentariness. While most studies and policy guidelines focus on physical activity interventions, there is a lack of data on the …
