Neuromuscular electrical stimulation (NMES) is an involuntary mode of inducing muscle contractions that has been used to prevent muscle immobility, weakness, strength loss, and muscle loss in rehabilitative settings. However, the additive effects of NMES and RT are not well established. PURPOSE:. To determine if superimposing neuromuscular electrical stimulation during a resistance training intervention elicits greater gains in muscle strength and/or muscle mass than resistance training being performed alone. METHODS: An electronic …
Effect Of Gait Speed On Knee Extensor Eccentric Control During Unpredictable Abrupt Gait Termination, Linda Steele, Mckenna Wehrmann, Jaci Adams
Effect Of Gait Speed On Knee Extensor Eccentric Control During Unpredictable Abrupt Gait Termination, Linda Steele, Mckenna Wehrmann, Jaci Adams
International Journal of Exercise Science: Conference Proceedings
Unpredictable gait termination is an important and common functional ability to prevent pedestrian accidents and/or falls. To dissipate kinetic energy and recover balance during unpredictable gait termination, knee extensor eccentric control in the stopping leg decelerates forward momentum and absorbs downward ground impact resisting body weight against gravity. Therefore, knee extensor eccentric control plays an important role in balance recovery as the initial defense against falls during unpredictable abrupt gait termination. In real world scenarios, required walking speeds are unpredictable and ever-changing. However, the influence of gait speed on the characteristics of knee extensor eccentric control during unpredictable abrupt gait …

Obesity Contributes To An Attenuated Spontaneous Baroreflex Sensitivity In Ucd-Type 2 Diabetic Rats, Milena Samora, Yu Huo, Richard K. Mcculler, Suchit Chidurala, James Graham, Kimber L. Stanhope, Peter J. Havel D.V.M., Ph.D., Audrey J. Stone, Michelle L. Harrison
International Journal of Exercise Science: Conference Proceedings
Previous studies suggest impaired baroreflex function in individuals with type 2 diabetes (T2D), which is critically important since it leads to an increased risk for adverse cardiovascular events. Currently, the underlying mechanisms remain poorly understood. The baroreflex, essential for maintaining blood pressure homeostasis, can also be influenced by several risk factors, one of which is obesity. Obesity has been shown to markedly decrease baroreflex sensitivity (BRS) in non-diabetic individuals, and given that the majority of T2D patients are obese, it is likely that impairment in baroreflex function in T2D is mainly driven by obesity. PURPOSE: To investigate the effects …

Gaining a better understanding of self-talk (ST) or interior dialogue while performing a novel psychomotor task (mirror tracing task) was explored using a phenomenological approach in which recorded results were compared to the ST data of diverse research disciplines. PURPOSE: The purpose of this study was to more fully understand ST (what) and its reported functions (why) while performing a fine motor task. METHODS: Participants, asked to complete three trials of the task, were presented with two open-ended questions regarding their inherent ST before, during and after each trial of the task: (1) self-reported ST, “What specific ST are …

Handgrip peak force and rate of force development (RFD) measurements have been shown to be effective parameters at characterizing the strength capacities of numerous muscle groups, including those of the lower extremities. However, the reliability of these measurements and their relationship with vertical jump (VJ) peak power remains uncertain. PURPOSE: The purpose of this study was to examine the reliability of handgrip peak force and RFD measurements. A secondary aim was to determine if these measurements are correlated with the peak power produced during a VJ test. METHODS: Twenty young, healthy women (age = 21 ± 3 years) …
