International Journal of Exercise Science: Conference Proceedings

Aim: We investigated the effect of macrophage differentiation on the chemotactic activity to invade local damaged muscle using in vitro models of muscle injury. Methods: C2C12 cell myoblasts, and J774 cell macrophages were used. The “killed-C2C12” cells were combined with live C2C12 cells (live:killed C2C12 = 1:0.5) as a partially damaged muscle model. The J774 cells were stimulated with LPS and DEX. The chemotactic activity of J774 cells was examined using TAXIScan device. Results: Although the velocity of J774 cells was little affected by each type of C2C12 cells (live, killed and combination), the directionality of the J774 cells was …

The Relationship Between Percent Change In Salivary Α-Amylase Activity And Fitness Level (Vo2peak And Anaerobic Threshold) Following Maximal Cycling Exercise In Moderately Trained Male Individuals, Nobuo Yasuda

International Journal of Exercise Science: Conference Proceedings

PURPOSE: Salivary α-amylase has been proposed as a biomaker for autonomic nervous system activity as well as mucosal immune function given that its realase into saliva is elicited by the stimulation of the salivary glands by sympathetic and parasympathetic activities. Clarifying how a individual’s fitness level will influence on the secretion of salivary α-amylase in response to exercise is a critical biological determinant of vulnerability to psychological and physiological stress. Although previous studies have shown the correlation between salivary α-amylase and exercise intensity, the relationship between autonomic nervous system activity and fitness level such as peak oxygen uptake (VO_{2 …}

Auto Anti Oxldl, Igm And Igg: Comparison Between Sedentary And Athletes, Juliana M B Santos, André L L Bachi, Francisco J O Rios, Tiago L. Capel, Pedro H C Vaisberg, Gislene R. Amirato, Mauro Vaisberg

International Journal of Exercise Science: Conference Proceedings

Introduction: The practice of regular physical activity contributes to reduce the prevalence of coronary hearth disease (CHD) and aerobic exercises are associated with beneficial changes in the profile of circulating lipids and lipoproteins. However in the past years the oxidative hypothesis assumed great importance in the pathogenesis of CHD. During exhaustive exercises there is a greater possibility of oxidation of LDL, forming oxidized LDL (oxLDL) that has a key role in atherogenesis. However the incidence of coronary events in athletes is lower than in sedentary persons. It is described in the literature that we can found in serum auto autoantibodies …

Inflammation And Resolution In Exercise-Induced Skeletal Muscle Injury: The Effect Of Nsaid Treatment On Pro-Inflammatory And Anti-Inflammatory/Pro-Resolving Lipid Mediators., James F. Markworth, Luke Vella, Krishna R. Maddipati, David Cameron-Smith

International Journal of Exercise Science: Conference Proceedings

Current approaches in the treatment of exercise-induced muscle injury rely on the inhibition of pro-inflammatory pathways to alleviate cardinal signs of inflammation; redness, swelling, heat and pain. However, recent research suggests that the cellular events which occur early in acute inflammation engage an active and coordinated inflammatory resolution program characterised by a switch from pro-inflammatory mediators to production of active pro-resolution factors that govern the withdrawal of inflammation whilst facilitating tissue healing. This led to the identification of novel classes of anti-inflammatory/pro-resolving lipid mediators, including the lipoxins (LX), resolvins (Rv), and protectins (P), which may provide new targets in the …

The Impact Of Match-Play Tennis On Indirect Markers Of Oxidative Stress And Antioxidant Status, Wade L. Knez, Mohammed Farooq, Julien Périard

International Journal of Exercise Science: Conference Proceedings

Introduction: Research has shown that both heat stress and endurance exercise can result in an increase in oxidative stress; however, there is limited information regarding the impact of the combination on oxidative balance, in particular an exercise bout characterised by high-intensity long-duration intermittent activity such as tennis. The purpose of this study was to determine the impact of changes in oxidative stress and antioxidant status in response to two simulated tennis matches undertaken in cool (≈22° and 70%RH) and hot (≈36° and 35%RH) environments. Methods: Twelve high level (ITF rank 2-3) male tennis players volunteered to participate in the matches …

Relation Between Tnf-Alpha And Exercise Induced Bronchoconstriction, Juliana M B Santos, Luiz A. Luna Jr, Ana P R Sierra, Luiz A R Costa, André L L Bachi, Mauro Vaisberg

International Journal of Exercise Science: Conference Proceedings

Introduction: Exercise-induced bronchoconstriction (EIB) describes an acute airway narrowing that occurs as a result of exercise. EIB is associated with a hyperosmolar environment that lead to airway smooth muscle contraction. The proinflammatory cytokine, TNF-alpha, has a prominent role in the development of airway hiperresponsiveness (AHR). A single bout of heavy exercise can trigger EIB. The aim of this research was to compare the response of TNF-alpha over time with the presence or absence of EIB in marathon runners. Methods: Thirty-eight male runners, who did not have any chronic or acute airway disease, performed maximal cardiopulmonary exercise testing on a treadmill …

Exhaustive Exercise Enhances Immune Response To Flagellin Via Adrenaline-Mediated Up-Regulation Of Tlr5 Expression, Uchida Masataka, Oyanagi Eri, Miyachi Motohiko, Kremenik J. Michael, Onodera Sho, Yano Hiromi

International Journal of Exercise Science: Conference Proceedings

Objective: We already reported that lipopolysacchride (LPS)-induced tumor necrosis factor (TNF)-α production as a bacterial infection model to induce immune response, was inhibited by exhaustive exercise. However, it remains unclear whether or not the immune response to flagellin (FG), which binds to toll like receptor 5(TLR5) and induces pro-inflammatory cytokine production, is also inhibited by this severe exercise. The aim of this study was to determine whether or not exhaustive exercise affects TNF-α productions after FG injection in mice. Methods: Both exhaustive-exercised (EX; n=12) and non-exercised (N-EX; n=12) male C3H/HeN mice were injected with FG (1 mg/kg, i.v), and blood …

Changes Of Cytokines In Mouse Skeletal Muscle And Plasma By A Single Bout Of Endurance Exercise., Minjung Lee, Noriaki Kawanishi, Koichi Yada, Yungli Hung, Tsubasa Mizokami, Hiroyuki Niihara, Katsuhiko Suzuki

International Journal of Exercise Science: Conference Proceedings

Introduction: Exercise influences some cytokine levels, which is considered the body’s reaction against endogenous stress. Previous human studies demonstrated that high intensity exercise contributes to a dramatic increase of plasma cytokines like Interleukin-6 (IL-6) and Interleukin-1 receptor antagonist (IL-1ra) immediately after exercise. Recently, it has been identified that skeletal muscle produces cytokines and peptides and they exert both paracrine and endocrine effects. However, the sequential changes of cytokine production according to exercise conditions such as intensity, types and working time are still unclear. In this study, we identified the sequential changes of cytokines in both skeletal muscle and plasma after …

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 …

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 …

Eight experienced, competitive weightlifters (six males, two females) completed both an AEL and NOR squat session (seven days apart), comprised of nine sets of squats, and was identical to their normal scheduled training. sEMG data from the vastus medialis (VM), vastus lateralis (VL), and biceps femoris (BF) was collected (at 1000Hz) during the entirety of the concentric (CON) phases of the AEL and NOR sessions. RMANOVAs (set x session-type) …

Neuromuscular Fatigue Following A Singles Badminton Match, Zengyuan Lin

Theses: Doctorates and Masters

A typical badminton singles match involves numerous intense and high impact movements. Lunges were accounted for approximately 15% of overall movements and were believed to presumably induce significant muscle damage following a match. However, no previous study has investigated changes in knee extensor muscle function after a badminton match.The present study investigated changes in knee extensor neuromuscular function and muscle soreness after a simulated 1-h badminton singles match in relation to the number of lunges performed in the match.

Ten state-level male badminton players were recruited (n=10), with each player played a total of eight simulated 1-h matches under the …

Pain Assessment And Possible Mechanism Of Delayed Onset Muscle Soreness, Wing Yin Lau

Theses: Doctorates and Masters

Muscle pain is felt during exercise or daily activities for several days after performing unaccustomed exercise, which is referred to as delayed onset muscle soreness (DOMS). Many people experience DOMS, but its underlying mechanisms are not fully understood. One of the challenges in the investigation of DOMS is its subjective nature, which makes the assessment ambiguous, thus establishing a standardised protocol is necessary. The present thesis scrutinised muscle pain assessments (Study 1, Study 2), developed a new assessment of muscle pain focusing on muscle fascia (Study 3), and investigated why DOMS is reduced after the second than the first bout …

Isokinetic Fatigue Characteristics For The Leg Extensors Versus Flexors, Elias M. Carrillo, Matt S. Stock, Jacob A. Mota, Kendra D. Olinghouse, Alexander S. Drusch, Brennan J. Thompson

Kinesiology and Health Science Faculty Publications

Maximal isokinetic muscle actions are often used in research studies to examine fatigability and even estimate muscle fiber-type. However, the majority of previous investigations have examined these topics for the leg extensors (i.e., quadriceps), and we are unaware of investigations that have specifically assessed the fatigue characteristics for the flexors (i.e., hamstrings). The purpose of this study was to compare the percent decline values for the leg extensors versus flexors for 50 and 100 repeated, maximal concentric isokinetic muscle actions. Fifteen healthy men (mean ± SD age = 23 ± 3 years; body mass = 94.1 ± 11.9 kg) with …

Peri-Exercise Co-Ingestion Of Branched-Chain Amino Acids And Carbohydrate In Men Does Not Preferentially Augment Resistance Exercise-Induced Increases In Pi3k/Akt-Mtor Pathway Markers Indicative Of Muscle Protein Synthesis, Maria Pontes Ferreira, Rui Li, Matthew Cooke, Richard B. Kreider, Darryn S. Willoughby

Nutrition and Food Science Faculty Research Publications

The effects of a single bout of resistance exercise (RE) in conjunction with peri-exercise branched chain amino acid (BCAA) and carbohydrate (CHO) ingestion on skeletal muscle signaling markers indicative of muscle protein synthesis (MPS) were determined. It was hypothesized that CHO + BCAA would elicit a more profound effect on these signaling markers compared to CHO. Twenty-seven males were randomly assigned to CHO, CHO + BCAA, or placebo (PLC) groups. Four sets of leg presses and leg extensions were performed at 80% 1RM. Supplements were ingested 30 min and immediately prior to and after RE. Venous blood and muscle biopsy …

ETSU Faculty Works

Objectives: The purpose of this investigation was to determine what effect a bilateral strength training regimen has on isometric force production symmetry and if changes in force production symmetry can be accounted for by differences in pre-intervention strength levels. Design: Sixteen recreationally trained males (1-RM squat: 146.8 ± 23.0 kg.) were assigned to two groups for the 7-week training intervention: strong (S) and weak (W) based on pre-training squat isometric peak force allometrically scaled (IPFa) at 120° knee angle. Methods: Subjects completed a 7-week training intervention following a block-periodized model and were tested on measures of dynamic (1RM squat) and …

The Relationship Of Force Production Asymmetry And Performance In Athletes Of Different Strength Levels, Christopher A. Bailey, Caleb D. Bazyler, Chieh-Ying Chiang, Kimitake Sato, Michael H. Stone

ETSU Faculty Works

The purpose of this study was to evaluate the relationship between force production asymmetry and performance of athletes with differing strength levels in males and females. Collegiate athletes (n=129) from various sports were ranked according to isometric mid-thigh pull peak force and the top (‘strong’) and bottom (‘weak’) 25% were used for analysis. Symmetry index (SI) scores were calculated and correlated with their respective force-time characteristics using bivariate correlations. For the weaker males, several negative moderate correlations were observed; however, no statistically significant correlations were observed for the females in either group. These findings indicate that force production asymmetry is …

Effects Of A Ten Week Barbell Deadlift Training Program On Vertical Jump Height In College-Aged Women, Kendra D. Olinghouse, Matt S. Stock, Jacob A. Mota, Elias M. Carrillo, Ibrahim K. Munayer, Jocarol E. Shields, Micheal J. Luera, Brennan J. Thompson

Kinesiology and Health Science Faculty Publications

The barbell deadlift is a large muscle mass exercise that primarily involves extension at the hip and knee joints. Although it is often incorporated into strength training programs with a variety of other exercises (e.g., back squat), no previous studies have examined the effects of deadlift training on strength or power adaptations. The purpose of this investigation was to examine the effects of a ten week barbell deadlift training program on vertical jump height in previously untrained women. Twenty-eight women (mean ± SD age = 22 ± 2 years) were randomly assigned to either the training group (n = 17) …
