The Current State Of Subjective Training Load Monitoring—A Practical Perspective And Call To Action, Joseph O. C. Coyne, G. Gregory Haff, Aaron J Coutts, Robert U. Newton, Sophia Nimphius

Research outputs 2014 to 2021

This commentary delivers a practical perspective on the current state of subjective training load (TL) monitoring, and in particular sessional ratings of perceived exertion, for performance enhancement and injury prevention. Subjective measures may be able to reflect mental fatigue, effort, stress, and motivation. These factors appear to be important moderators of the relationship TL has with performance and injury, and they also seem to differ between open and closed skill sports. As such, mental factors may affect the interaction between TL, performance, and injury in different sports. Further, modeling these interactions may be limited due to the assumption that an …

Participants were assessed in measures of cognition, mobility, and cardiovascular health at baseline, 3, 6, and 12 months (after a 6-month no-contact follow-up).

Results: We observed improvements in cognition in both groups at 6 and 12 months, although no …

Assessment Of Multiple Concussive Athletes With Dual Task Triple Stroop And Aerobic Exercise, Sierra Duran, Sarah A. Massey, Ariel Gomez, Matthew A. Barlow 5622543

International Journal of Exercise Science: Conference Proceedings

BACKGROUND: Athletic concussion testing has mostly recently relied on a sedentary computer neurocognitive test battery called the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Previous tests directly compare baseline with post-concussion analysis of patient in regards to different cognitive aspects including; working memory, processing speed, and response time. No physical tests are included in the ImPACT analysis for return-to-play action. PURPOSE: In previous studies from our lab in these populations we concluded that the combination of a physical neural impediment with cognitive tests (dual-task with balance impairment) created a greater degree of impairment not observed in the sedentary ImPACT test. …

Design An internet study was designed with five domains to understand physicians’: (1) overall perception of HC, (2) appropriateness and recommendation of HC and PT to their patients, (3) attitude regarding specific aspects of HC, (4) support of patient participation in HC sponsored exercise and (5) elements of HC that …

Interpreting Signal Amplitudes In Surface Electromyography Studies In Sport And Rehabilitation Sciences, Andrew D. Vigotsky, Israel Halperin, Gregory J. Lehman, Gabriel S. Trajano, Taian M. Vieira

Research outputs 2014 to 2021

Surface electromyography (sEMG) is a popular research tool in sport and rehabilitation sciences. Common study designs include the comparison of sEMG amplitudes collected from different muscles as participants perform various exercises and techniques under different loads. Based on such comparisons, researchers attempt to draw conclusions concerning the neuro- and electrophysiological underpinning of force production and hypothesize about possible longitudinal adaptations, such as strength and hypertrophy. However, such conclusions are frequently unsubstantiated and unwarranted. Hence, the goal of this review is to discuss what can and cannot be inferred from comparative research designs as it pertains to both the acute and …

The Effects Of Acute And Chronic Sprint-Interval Training On Cytokine Responses Are Independent Of Prior Caffeine Intake, Guilherme Ferreira, Leandro Felippe, Rômulo Bertuzzi, David Bishop, Emiliano Barreto, Fernando De-Oliveira, Adriano Lima-Silva

Research outputs 2014 to 2021

We examined the effect of acute and chronic sprint interval training (SIT), with or without prior caffeine intake, on levels of exercise-induced inflammatory plasma cytokines [interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)-α]. Twenty physically-active men ingested either a placebo (n = 10) or caffeine (n = 10) 1 h before each SIT session(13-s × 30-s sprint/15 s of rest) during six training sessions (2 weeks). The early (before, immediately after, and 45 min after the exercise) and late (24 and 48 h after the exercise) cytokine and creatine kinase (CK) responses were analyzed for the first and last …

Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.

Graduate Student Theses, Dissertations, & Professional Papers

Interleukin-6 (IL-6) was first identified as a pleiotropic cytokine, with a host of body-wide functions. Cytokine functions are characterized by chronically elevated levels within various inflammatory states. In this regard, IL-6 is largely associated with the acute phase response to many stimuli and performs specific actions when produced from certain cell types. Accrued evidence indicates IL-6 release from skeletal muscle often includes myokine functions. Novel myokine functions are adaptive in nature, and as compared to inflammatory/cytokine roles, exhibit a transient time course. Following exercise plasma IL-6 peaks and returns to resting levels within 1-2 hours. In contrast, IL-6 is observed …

Youth Leisure-Time Physical Activity From The Perspectives Of Young Adults With Visual Impairments, Justin A. Haegele

Human Movement Sciences & Special Education Faculty Publications

The purpose of this study was to examine the meaning that young adults with visual impairments ascribe to their youth leisure-time physical activity experiences. This study adopted an interpretative phenomenological analysis (IPA) research approach. Ten participants (aged 21-34 years; eight women, two men) with visual impairments were included in this study. Semi-structured, audio-taped telephone interviews acted as the primary source of data for this study. Data were analyzed thematically using a four-step process informed by IPA and three interrelated themes were constructed: (a) "I just always felt normal when I was doing them": Preferences for unstructured activities, (b) "They didn't …

Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin

Theses: Doctorates and Masters

Many studies have reported the relationship between exercise and cognition with conflicting results. This may be due to differences in intervention durations, session lengths, intensities, and type of exercise. It has been suggested that exercises requiring greater cognitive demand such as football, basketball and racquet sports, are protective against cognitive decline, compared to less cognitively demanding exercises such as swimming, cycling and running, however, research concerning exercise types are currently limited. The present study tested the hypothesis that elderly individuals who had been regularly playing tennis more than 10 years, would have greater cognitive function than those who had been …
