Exercise Selectively Mobilises Skin-Homing Effector Cd8+ T Cells And Natural Killer Cells Into Peripheral Blood., John P. Campbell, James E. Turner, Alex Wadley, Jos A. Bosch, Mark T. Drayson, Sarah Aldred

International Journal of Exercise Science: Conference Proceedings

Introduction: Acute exercise induces a transient mobilisation of lymphocyes into peripheral blood that is largely comprised of CD8+ T cells and natural killer (NK) cells. The magnitude of this response is dependent on the differentiation status of these lymphocyte subsets, thus cells with a capacity to initiate rapid effector function (i.e., cytokine secretion and target killing) exhibit the largest changes in response to exercise. It is hypothesised that the effector cells preferentially mobilised into the bloodstream have high tissue-migrating potential, however, the origin of these cells, and their potential homing destination(s) following exercise has not been established in humans. Accordingly, …

Effect Of Ageing And Exercise Training On Myokine Expression Responses To Acute Exercise, Paul A. Della Gatta, Michelle M. Farnfield, Jonathan M. Peake, Andrew P. Garnham, David Cameron-Smith

International Journal of Exercise Science: Conference Proceedings

Age-related muscle loss is a major contributor to falls, fraility and mortality. It has been widely suggested that chronic, age-related inflammation contributes to the gradual loss of skeletal muscle mass that occurs with ageing. Indeed, ageing is associated with elevations in a number of circulating inflammatory proteins, many of which have detrimental effects on skeletal muscle growth and protein balance. Exercise training has been shown to reduce chronic inflammation and, therefore, may represent an appropriate means to reduce age-related inflammation and counteract sarcopenia. Yet few studies have evaluated the effect of aging on skeletal muscle expression of inflammatory proteins and …

Infections And Immune Disturbances: Clinical-Based Outcomes, Stephane Bermon

International Journal of Exercise Science: Conference Proceedings

Whatever their level or type of sport practice, athletes are exposed to infectious diseases or immune-related problems. This susceptibility is partly explained by exercise-induced immuno-suppression. Moreover, many athletes are exposed to either pathogens or physico-chemical influences while practising their sports. Indeed, the respiratory tract, the digestive tract as well as the skin and mucosa can be seriously challenged in some aerobic outdoor or indoors sports as well as in some contact sports. At the upper respiratory tract level, and especially after exercise-associated hyperventilation, symptoms may develop, but it is sometimes difficult for the medical staff to confirm any infectious origin. …

Genome-Wide Translational Profiling Of The Inflammatory Response Of Macrophages To Lps, Hiroaki Sako Mr, Katsuhiko Suzuki Prof.

International Journal of Exercise Science: Conference Proceedings

Introduction: Exercise causes both inflammation and anti-inflammation and the details are complex. Genome-wide analysis, including proteomics or RNA sequencing (RNA-seq), is beneficial to reveal the complexity and to screen novel factors. However, there are some difficulties. Proteomics shows low reproducibility and analytical bias (eg., hydrophilic and hydrophobic proteins). Although RNA-seq or microarray present robust reproducibility, it has been known that the correlation of mRNA and protein levels is low (R² = 0.17 ~ 0.41). This is due to translational regulation. Considering translational efficiency, the correlation is boosted to R² = 0.95.

In 2009, newly introduced technique based …

Healthy Body Healthy Mind: Trialling An Exercise Intervention For Reducing Depression In Youth With Major Depressive Disorder, Robin Callister Prof, Adriana Giles, Yasmina Nasstasia, Amanda L. Baker, Ben Dascombe, Sean Halpin, Leanne Hides, Brian Kelly

International Journal of Exercise Science: Conference Proceedings

Introduction: Major Depressive Disorder (MDD) has high prevalence among adolescents and young adults but evidence of any effective treatments is limited. Exercise as an effective treatment for adults has some support but studies in younger populations are lacking. MDD is associated with inflammation and exercise may contribute to reductions in inflammatory marker levels. Therefore the aim of this study was to investigate the feasibility and preliminary efficacy of brief motivational interviewing (MI) plus 12-weeks exercise training as a treatment for MDD in youth.

Methods: Youth (15-25 years) with MDD were recruited to participate in a prospective trial investigating exercise as …

On The Joys Of Missing Data, Todd D. Little, Terrence D. Jorgensen, Kyle M. Lang, E. Whitney G. Moore

Kinesiology, Health and Sport Studies

We provide conceptual introductions to missingness mechanisms—missing completely at random (MCAR), missing at random (MAR), and missing not at random (MNAR)—and state-of-the-art methods of handling missing data—full-information maximum likelihood (FIML) and multiple imputation (MI)—followed by a discussion of planned missing designs: multiform questionnaire protocols, two-method measurement models, and wave-missing longitudinal designs. We reviewed 80 articles of empirical studies published in the 2012 issues of the Journal of Pediatric Psychology to present a picture of how adequately missing data are currently handled in this field. To illustrate the benefits of utilizing MI or FIML and incorporating planned missingness into study designs, …

Age And Practice Effects On Inter-Manual Performance Asymmetry, Karen Francis, P G. Macrae, Waneen Spirduso, Tim Eakin

Kinesiology (Formerly Exercise and Sport Science)

Manual dexterity declines with increasing age, however, the way in which inter-manual asymmetry responds to aging is unclear. Our purpose was to determine the effect of age and practice on inter-manual performance asymmetry in an isometric force pinch line tracing task that varied in difficulty within segments. Thirty right-handed participants, five males and five females in each of three age groups, young (Y20), young–old (O70), and old–old (O80), practiced an isometric force pinch task for 10 trials with each hand on each of five consecutive days. Inter-manual performance asymmetry of the right and left hands was analyzed with a repeated …

Applying The Social Ecological Model To Violence Against Women With Disabilities, Miranda Sue Terry

Faculty Publications

Violence against women (VAW) is a broad term used to capture aggressive acts committed toward women, which consists of numerous types of violence with the most commonly known types of abuse being emotional, sexual, and physical. One relatively invisible group, women with disabilities, not only experiences emotional, sexual, and physical abuse but also a unique type of disability-related abuse, which may increase their risk of experiencing acts of violence. The U.S. Congress passed two distinct yet not mutually exclusive policies into law to address violence against women and rights for individuals with disabilities: the Violence against Women Act and the …

The Importance Of Managing Psychosocial Health: A Case Study, Mary Insana Fisher, Harold L. Merriman

Physical Therapy Faculty Publications

Managing the physical aspects of lymphedema requires an individual to be committed to daily treatment of this chronic condition. Performing manual lymph drainage, using compression bandaging or compression garments, exercising, and caring for the skin all take time and a high level of dedication. This commitment to self-care can be emotionally and psychologically exhausting.

When coupled with other emotional stressors in a patient’s life, successful treatment of lymphedema is challenging. We present a case demonstrating how the physical and psychological aspects of care interplay, and, when well-managed, can positively affect the outcome.

Acute Effect Of Caffeine Intake On Hemodynamics After Resistance Exercise In Young Non-Hypertensive Subjects, Diego Souza, Juliano Cosanatto, Roberto Poton, Jeffrey Willardson, Marcos Polito

Faculty Research and Creative Activity

This study aimed to examine the effect of caffeine on hemodynamics after a resistance exercise session. Fifteen subjects completed two randomly ordered experimental resistance exercise sessions 45 min after the ingestion of either caffeine (4 mg.kg-1) or placebo. Systolic (SBP), diastolic (DBP) and mean (MAP) blood pressures were measured before consuming caffeine; SBP, DBP, MAP, heart rate, stroke volume, cardiac output and peripheral vascular resistance (PVR) were measured immediately before and after each of the sessions; SBP, DBP and MAP were measured for 9 hours after sessions. Caffeine increased (p < 0.05) pre-exercise DBP and MAP. In caffeine and placebo conditions significant decreases (p < 0.05) were noted in SBP, MAP, and PVR between the pre- and post-exercise time points. Notwithstanding, the mean values for SBP, DBP and MAP during the 9 h of post-exercise monitoring were increased (p < 0.05) for the caffeine. In conclusion, the cardiovascular effects of caffeine are different over the post-exercise period after resistance exercise in normotensive young adults.

Kinesiology and Public Health

There are few studies of built environment associations with physical activity and weight status among older women in large geographic areas that use individual residential buffers to define environmental exposures. Among 23,434 women (70.0±6.9 years; range = 57-85) in 3 states, relationships between objective built environment variables and meeting physical activity recommendations via walking and weight status were examined. Differences in associations by population density and state were explored in stratified models. Population density (odds ratio (OR)=1.04 [1.02,1.07]), intersection density (ORs=1.18-1.28), and facility density (ORs=1.01-1.53) were positively associated with walking. Density of physical activity facilities was inversely associated with overweight/obesity …
