Assessment Of Neutrophil Functional Activity Following Prolonged Endurance Exercise, Katsuhiko Suzuki, Kaoru Sugama, Kayo Yoshitani, Koso Shiraishi, Takashi Kometani, Shigeki Miura, Hiroshi Yoshioka, Yuichi Mori

International Journal of Exercise Science: Conference Proceedings

Introduction: Neutrophils not only play an important role in host defense by migrating to the site of infection and producing reactive oxygen species (RO S), but also mediate pathological process in inflammatory tissue damage. Therefore, it is import ant not only to assess but also modulate neutrophil activities for disease prevention. We hav e reported that exhaustive exercise causes neutrophil priming (Suzuki et al. J. Appl. Physiol. , 81, 1213-1222, 1996) which might be associated wi th muscle damage (Suzuki et al. J. Appl. Physiol. , 87, 1360-1367, 1999), but antioxidant capacity is also activated following exercise (Suzuki et al. …

Running Economy And Cytokines: What The Influence Of Il-6 And Il-10?, Luiz Luna Jr., Roberta Paiva, Ana Sierra, Andre Bachi, Pedro Vaisberg, Mauro Vaisberg

International Journal of Exercise Science: Conference Proceedings

Introduction: During the exercise performing the muscle produce cytokines, named “myokines”. These molecules show autocrine, paracrine and endocrine effects. One of them IL-6 demonstrates both pro and anti-inflammatory actions. Usually they have an anti-inflammatory action when produced by working muscles and when produced by other tissues, especially adipose, they assume a pro-inflammatory profile. Athletes´ performance, especially those that run long distances races (endurance) is associated with higher levels of maximal oxygen uptake (VO2max). Running economy (RE) is a methodology used to evaluate the performance of runners and is defined as "the rate of oxygen consumption (VO2) required for maintain …

Physical Exercise And Its Implications For Aging Immunity And Adoptive Transfer Immunotherapy, Richard J. Simpson

International Journal of Exercise Science: Conference Proceedings

Advancing age is associated with a profound decline in the normal functioning of the immune system that is commonly referred to as immunosenescence. Impaired responses to vaccination and the increased incidence of infection and malignancy seen in the elderly are often considered to be a direct consequence of immunosenescence. A large body of cross-sectional data has shown that habitual exercise is associated with enhanced functional responses in both the innate and adaptive arms of the aging immune system, indicating that exercise may help curtail the onset of immunosenescence. However, it is not known if exercise is also capable of reversing …

Exploring The Mechanisms Behind The Effects Of Chronic Bovine Colostrum Supplementation On Risk Of Upper Respiratory Tract Infection, Arwel W. Jones, Rhys Thatcher, Luis A J Mur, Simon J S Cameron, Marikka Beecroft, Glen Davison

International Journal of Exercise Science: Conference Proceedings

Chronic bovine colostrum (COL) supplementation has been shown to reduce the incidence of upper respiratory tract infection (URTI) but the underlying mechanism remains unclear. Fifty seven highly active males (aged 18-62) were randomised to daily supplementation of 20g of COL (N = 28) or an isoenergetic/isomacronutrient placebo (PLA) (N = 29) for 12 weeks under double-blind procedures. Daily illness and weekly activity logs were completed. Resting blood samples collected at baseline and at 12 weeks were analysed for total/differential leukocyte counts and in-vitro stimulated neutrophil oxidative burst. Metabolomic profiling of serum samples at these timepoints was performed using fourier transform …

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 …
