Use Of Objective Tools For Early Detection Of Parkinson’S Symptoms, Brett Weinstein, Alex Rothstein, Danny Chan, Andreana Zazzarino, Brianna Singh, Meredith Fagan, Dominique Torres, Charles Siguenza, Rosemary Gallagher

International Journal of Exercise Science: Conference Proceedings

Parkinson’s disease (PD) is characterized by asymmetrical motor symptoms that are difficult to detect early, thus the need for more sensitive tools. People with early PD (PwPD) participate in high level physical activity, are susceptible to injury, and in need of exercise professionals (EP). However, assessment tools used by EPs for healthy populations may be underutilized in PD. We suggest these tools can quantify early lower extremity (LE) motor impairments otherwise not found during the Five Times Sit to Stand test (FTSTS), commonly used to assess LE strength and function in the rehabilitation setting. PURPOSE: Examine LE asymmetry, force and …

International Journal of Exercise Science: Conference Proceedings

Regular exercise is known to confer substantial benefits for cardiovascular health. However, long-distance runners with abnormal exercise electrocardiography like ST-segment depression have been reported to show a higher prevalence of exercise-induced hypertension, which may link to future cardiovascular events. In recent years, the recommendation to screen and assess cardiovascular risks has extended to various populations including chronically active and seemingly healthy older athletes. PURPOSE: In the retrospective analysis of a previous research study to evaluate walking economy in older adults, we observed a fairly high occurrence of both ST segment depression and peak systolic BP in older endurance-trained athletes. …

Vascular Responses During Steady-State Exercise In Adults With Type 1 Diabetes, Ruby A. Nyarko, Ashlesha D. Dalve, Justo Perez Iii, Pratima V. Kumar, Jasdeep Kaur

International Journal of Exercise Science: Conference Proceedings

Type 1 diabetes (T1D) is associated with widespread hyperglycemia-induced vascular damage, which affects both conduit and resistance arteries. This damage has been demonstrated by impaired vasodilatory responses to a 5-minute ischemic stimulus (flow-mediated dilation) and infusion of pharmacological vasodilators in patients with T1D. However, whether this vascular impairment affects blood flow regulation during steady-state exercise in T1D remains unclear. PURPOSE: Herein, we tested the hypothesis that adults with T1D would exhibit blunted forearm blood flow (FBF) and forearm vascular conductance (FVC) during steady-state rhythmic handgrip exercise (RHG), compared to age-matched healthy controls. METHODS: We studied 27 adults (15 …

Females Experience Greater Relative But Similar Absolute Neuromuscular Fatigue Than Males During A Ramp-Incremental Exercise Test, Jeff Moore, Daniel T. Cannon, Harry B. Rossiter Facsm, Carrie Ferguson

International Journal of Exercise Science: Conference Proceedings

Sex differences in pulmonary, cardiovascular, or neuromuscular function may affect the development of neuromuscular fatigue and the primary mechanism of exercise intolerance. Unlike the standard cardiopulmonary exercise test (CPET), the musculo-cardio-pulmonary exercise test (mCPET) uses isokinetic power (Piso) to directly assess neuromuscular performance and fatigue. PURPOSE: : To examine sex differences in neuromuscular performance and fatigue during mCPET. We hypothesize that compared to females, males will have greater power (baseline Piso), lower capacity to aerobically support their available muscle power (lower aerobic power index; API), greater reduction in Piso per watt of work performed (higher fatigue index; FI), be …
