Subjects performed a warm-up on the treadmill at 40% of their heart rate reserve for 5 minutes, then for 30 minutes did continuous walking or jogging on the treadmill at ~67 ...


Longitudinal, Diet-Induced Weight Gain Is Associated With Increased Blood Monocytes And Reduced Tlr4 Expression, Kelley Strohacker, Richard J. Simpson, Katie C. Carpenter, Whitney L. Breslin, Brian K. McFarlin 2010 University of Houston - Main

Longitudinal, Diet-Induced Weight Gain Is Associated With Increased Blood Monocytes And Reduced Tlr4 Expression, Kelley Strohacker, Richard J. Simpson, Katie C. Carpenter, Whitney L. Breslin, Brian K. Mcfarlin

International Journal of Exercise Science

Excessive weight gain increases systemic inflammation resulting in increased disease risk. Toll-like receptor 4 (TLR4) reportedly mediates increases in inflammation; however, its role has not been fully evaluated. Objective. The purpose of this study was to determine the longitudinal effect of diet-induced weight gain on blood monocyte concentration and cell-surface TLR4 expression. Research Methods & Procedures. Male CD-1 mice were randomly assigned to high-fat (HF, n = 12) or low-fat (LF, n = 13) groups. Non-lethal, saphenous vein blood samples were collected at 0, 4, 8 and 12 weeks of treatment. Three-color flow cytometry was used to measure monocyte (CD11b+/CD14+) concentration and TLR4 cells-surface expression. Data were analyzed with a repeated measures ANOVA; significance was set at P<0.05. Results. Body weight at week 12 was 21% greater in HF than LF (P<0.05). At week 12 HF had 155% more monocytes (P<0.05) with 24% less TLR4; Monocyte concentration and body weight at week 12 was negatively correlated with TLR4 gMFI (P<0.05). Conclusions. The observed effects of high-fat feeding on blood monocytes are consistent with a phenotype, which may be associated with premature morbidity. The observed monocyte responses may be associated with immune dysfunction and diminished response to infection.

LBIA measured %BF values were obtained immediately before and within five minutes after completing a structured, in-school, physical education ...


Does Standing On A Cycle-Ergometer, Towards The Conclusion Of A Graded Exercise Test, Yield Cardiorespiratory Values Equivalent To Treadmill Testing?, Joshua Mitchell, William B. Kist, Kendall Mears, Jesse Nalls, Kyle Ritter 2010 Southern Arkansas University-Magnolia

Does Standing On A Cycle-Ergometer, Towards The Conclusion Of A Graded Exercise Test, Yield Cardiorespiratory Values Equivalent To Treadmill Testing?, Joshua Mitchell, William B. Kist, Kendall Mears, Jesse Nalls, Kyle Ritter

International Journal of Exercise Science

Graded exercise testing (GXT), per a cycle-ergometer (CE), offers safety and monitoring advantages over treadmill (TM) GXT. Unfortunately, CE-VO2max and some other cardiorespiratory (CR) variables are frequently lower than TM-GXT values. It has been difficult to compare TM and CE-GXT values. However, it was hypothesized that standing towards the conclusion of the CE-GXT (Stand-CE) might increase CE values to those equal to TM-GXT. If Stand-CE and TM-GXT CR values were equal, Stand-CE-GXT could become the method of choice for GXT for the general population. The purpose of this investigation was to investigate the effect of Stand-CE on CR variables. An ...

The present study was taken up to monitor the training load and the impact of training load to the hormone concentrations such as testosterone, cortisol and T/C (Testosterone/Cortisol) ratio during the three phases of training viz preparatory phase, pre-competitive phase and competitive phase in Indian male swimmers. Blood samples were collected at the completion of each phase and the hormone concentrations were quantified. Our results reveal that the testosterone and T/C ratio significantly decreases whereas cortisol increases in the subsequent periodised cycle and concludes that the hormone concentration changes with the intensity and duration of exercise i ...


Association Of Body Surface Area And Body Composition With Heart Structural Characteristics Of Female Swimmers, Bahreh Sheikh Saraf, Hojat Allah Nikbakht, Mohammad Ali Azarbayjani 2010 IA University, Najafabad Branch, Isfahan

Association Of Body Surface Area And Body Composition With Heart Structural Characteristics Of Female Swimmers, Bahreh Sheikh Saraf, Hojat Allah Nikbakht, Mohammad Ali Azarbayjani

International Journal of Exercise Science

In healthy nonathletic populations, some left ventricle (LV) parameters such as LV mass (LVM) and LV end diastolic dimension (LVEDD) can be predicted by some of body size parameters such as body surface area (BSA), fat-free mass (FFM), and height (H). These body size parameters use to remove covariate influence of body size from cardiac dimension variables and allow comparisons to be made between individuals and groups of different body size. Endurance exercise has been associated with changes in LV size and body composition of athletes. The aim of this study was to evaluate in 30 trained female swimmers (age ...


Objective And Subjective Assessments Of ‘Normal’ Walking Pace, In Comparison With That Recommended For Moderate Intensity Physical Activity, Kathryn L. Taylor, Claire Fitzsimons, Nanette Mutrie 2010 Teesside University, Middlesbrough, UK

Objective And Subjective Assessments Of ‘Normal’ Walking Pace, In Comparison With That Recommended For Moderate Intensity Physical Activity, Kathryn L. Taylor, Claire Fitzsimons, Nanette Mutrie

International Journal of Exercise Science

Abstract Despite its common application and widely reported health benefits, walking, in relation to pace and intensity, is under-researched. Few studies have addressed whether people normally walk at a pace which meets the public health recommendations for moderate intensity physical activity (1.34-1.79 ms-1) and there is no known research on individuals’ perceptions of factors which influence walking pace. This study aimed to objectively assess if participants were reaching the pace required for moderate intensity physical activity during ‘normal’ walking. This was examined via a Global Positioning System (GPS) over a 1 km outdoor walk and a timed 150 ...


Recreational Cyclists: The Relationship Between Low Back Pain And Training Characteristics, Samantha J. Schulz, Susan J. Gordon 2010 James Cook University

Recreational Cyclists: The Relationship Between Low Back Pain And Training Characteristics, Samantha J. Schulz, Susan J. Gordon

International Journal of Exercise Science

This study investigated the relationship between low back pain (LBP) and training characteristics in recreational cyclists. Purposive sampling was used to recruit sixty-six recreational cyclists from nine cycling clubs. Participants completed a survey reporting training characteristics and LBP behaviour during a usual week of cycling. This included percent of time spent cycling in three common riding positions, cycling terrain, average cycling pace, number of gears, days per week cycled and number of cycling events per year. Fifty percent reported LBP during or after cycling or smoking and LBP. Cyclists who reported LBP cycled significantly further in a usual week of ...


Delayed Wound Healing: Can Exercise Accelerate It?, K Todd Keylock, Hilary Young 2010 Bowling Green State University

Delayed Wound Healing: Can Exercise Accelerate It?, K Todd Keylock, Hilary Young

International Journal of Exercise Science

Poorly healing wounds affect millions around the world, yet preventive methods and low-cost, effective treatments are few. Wounds heal quickly through well-coordinated phases in those who are healthy and active but can become chronically nonhealing as a result of disease and inactivity. Recently it has been reported that moderate aerobic exercise accelerated healing rates in the aged. High levels of inflammation are known to delay wound healing, and aging and disease are associated with chronically increased inflammation. Therefore, exercise may help speed healing by reducing inflammation to healthier levels not only in the aged, but also in other populations with ...

BACKGROUND: Multiple uncontrolled medical conditions may act as competing demands for clinical decision making. We hypothesized that multiple uncontrolled cardiovascular risk factors would decrease blood pressure (BP) medication intensification among uncontrolled hypertensive patients.

METHODS: We observed 946 encounters at two VA primary care clinics from May through August 2006. After each encounter, clinicians recorded BP medication intensification (BP medication was added or titrated). Demographic, clinical, and laboratory information were collected from the medical record. We examined BP medication intensification by presence and control of diabetes and/or hyperlipidemia. 'Uncontrolled' was defined as hemoglobin A1c >/= for diabetes, BP >/= 140/90 mmHg ...

Robust Stimulation Of Humoral And Cellular Immune Responses Following Vaccination With Antigen-Loaded Beta-Glucan Particles, Habin Huang, Gary R. Ostroff, Chrono K. Lee, Charles A. Specht, Stuart M. Levitz

Infectious Diseases and Immunology Publications and Presentations

beta-Glucan particles (GPs) are purified Saccharomyces cerevisiae cell walls treated so that they are primarily beta1,3-d-glucans and free of mannans and proteins. GPs are phagocytosed by dendritic cells (DCs) via the Dectin-1 receptor, and this interaction stimulates proinflammatory cytokine secretion by DCs. As the hollow, porous GP structure allows for high antigen loading, we hypothesized that antigen-loaded GPs could be exploited as a receptor-targeted vaccine delivery system. Ovalbumin (OVA) was electrostatically complexed inside the hollow GP shells (GP-OVA). Incubation of C57BL/6J mouse bone marrow-derived DCs with GP-OVA resulted in phagocytosis, upregulation of maturation markers, and rapid proteolysis of ...

Previous work has shown that organosilica-based xerogels have the potential to control biofouling. In this study, modifications of chemistry were investigated with respect to their resistance to marine slimes and to settlement of barnacle cyprids. Adhesion force measurements of bovine serum albumin (BSA)-coated atomic force microscopy (AFM) tips to xerogel surfaces prepared from aminopropylsilyl-, fluorocarbonsilyl-, and hydrocarbonsilyl-containing precursors, indicated that adhesion was significantly less on the xerogel surfaces in comparison to a poly(dimethylsiloxane) elastomer (PDMSE) standard. The strength of adhesion of BSA on the xerogels was highest on surfaces with the highest and the lowest critical surface tensions ...

Rna Polymerase Mapping During Stress Responses Reveals Widespread Nonproductive Transcription In Yeast, Tae Soo Kim, Chih Long Liu, Moran Yassour, John Holik, Nir Friedman, Stephen Buratowski, Oliver J. Rando

Open Access Articles

BACKGROUND: The use of genome-wide RNA abundance profiling by microarrays and deep sequencing has spurred a revolution in our understanding of transcriptional control. However, changes in mRNA abundance reflect the combined effect of changes in RNA production, processing, and degradation, and thus, mRNA levels provide an occluded view of transcriptional regulation.

RESULTS: To partially disentangle these issues, we carry out genome-wide RNA polymerase II (PolII) localization profiling in budding yeast in two different stress response time courses. While mRNA changes largely reflect changes in transcription, there remains a great deal of variation in mRNA levels that is not accounted for ...

OBJECTIVES: Obesity is associated with an increased risk of heart failure (HF). Among patients presenting with acute HF, however, differences in clinical characteristics, treatment regimens, and short-term prognosis of varying weights are largely unknown, particularly from a broader population-based perspective. METHODS: A total of 3722 patients admitted with acute HF to 11 greater Worcester (Massachusetts, USA) hospitals during 1995 and 2000 were categorized as being lean (n = 216), normal weight (n = 1465), overweight (n = 1007), or obese (n = 1034) at the time of hospitalization. RESULTS: Obese patients with decompensated HF were significantly younger (mean age = 71 years) compared with patients ...
