Objective: This project was aimed at evaluating the impact of combat armor on physiological and cognitive functions during low-intensity exercise in hot-humid conditions (36°C and 60% relative humidity). Methods: Nine males participated in three trials (2.5 hours), walking at two speeds and wearing different protective equipment: control (combat uniform and cloth hat); torso armor with uniform and cloth hat; and full armor (uniform, torso armor, and helmet). Results: As time progressed, core temperatures increased and deviated signifi cantly among trials, rising at 0.37°C h −1 (control), 0.41°C h −1 (torso armor), and 0.51°C h −1 (full armor). Heart rates also …

The aim of this study was to examine the effect of endurance training on skeletal muscle phospholipid molecular species from high-fat fed rats. Twelve female Sprague- Dawley rats were fed a high-fat diet (78.1% energy). The rats were randomly divided into two groups, a sedentary control group and a trained group (125 min of treadmill running at 8 m/min, 4 days/wk for 4 weeks). Forty-eight hours after their last training bout phospholipids were extracted from the red and white vastus lateralis and analyzed by electrospray-ionization mass spectrometry. Exercise training was associated with significant alterations in the relative abundance of a …

Gestational diabetes mellitus (GDM) is associated with a marked increase in the long-term risk of type 2 diabetes and adverse pregnancy outcomes. Engaging in vigorous recreational physical activity prior to and during pregnancy significantly reduces the risk of developing GDM. In contrast, evidence of a therapeutic effect from participation in a structured exercise training regimen, although promising, is limited and requires further more substantial investigation. This paper briefly reviews the pathophysiology of GDM, the evidence related to physical activity participation and exercise regimen intervention on GDM, and the clinical considerations required for prescribing exercise. Key Words: gestational diabetes mellitus • …

When fluid intake is insufficient to match sweat losses, dehydration develops. It is well established that dehydration impacts unfavourably upon cardiovascular function, including cardiac output and peripheral blood flow (Gonzalez-Alonso et al., 1998). However, the limitations of cardiac electrophysiology in the dehydrated state are not known. In light of possible electrolyte imbalances, particularly when water deficit moves towards 7% of total body mass, it is worth considering the possibility of adverse conduction changes, as reflected within the electrocardiogram (ECG), may accompany electrolyte loss. In addition, the ECG can also be employed to investigate other cardiac limitations, such as myocardial ischaemia. …
Qigong As A Mindful Exercise Intervention For People Living With Mental Ill Health, Chris Lloyd, H. Tsang, Frank P. Deane

Background: Individuals with schizophrenia are more likely to be overweight or obese than the general population, and the associated health problems put them at a higher risk of death. Exercise is therefore an important non-pharmacological intervention that mental health workers can assist clients to engage in, and mindful exercise approaches may be particularly well-suited to this population. Content: This article describes the concept of qigong as a mindful exercise and looks at preliminary evidence suggesting that mindful exercise is of physical and emotional benefit to people with mental ill health. The authors propose an easy, standardized exercise protocol which clinicians …
Fish Oil Reduces Heart Rate And Oxygen Consumption During Exercise, Gregory E. Peoples, Peter L. Mclennan, Peter R. C Howe, Herbert Groeller

Dietary omega-3 polyunsaturated fatty acids (PUFAs) are readily incorporated into heart and skeletal muscle membranes where, in the heart, animal studies show they reduce O2 consumption. To test the hypothesis that omega-3 PUFAs alter O2 efficiency in humans, the effects of fish oil (FO) supplementation on O2 consumption during exercise were evaluated. Sixteen well-trained men (cyclists), randomly assigned to receive 8 x 1 g capsules per day of olive oil (control) or FO for 8 weeks in a double-blind, parallel design, completed the study (control: n = 7, age 27.1 +/- 2.7 years; FO: n = 9, age 23.2 +/- …

Background: People with end stage renal disease (ESRD) have been reported as having low levels of physical activity. Sedentary behaviours increase illness risks which may lead to burdens on the public health system which include costs of medical care. Research has established that exercise is reported to improve general health and wellbeing. Benefits include better aerobic tolerance, maintenance and improvement in physical function and capacity, and improvement in self-concept and well-being. These same improvements also occur in an exercising ESRD population, even though the improvements might be of less magnitude. Renal unit staff can have a major impact on patients …

Fifty patients with myocardial infarction were recruited from a hospital based Cardiac Education and Assessment Program (CEAP) in Sydney, Australia. The Exercise Motivation Inventory-2 (EMI-2) and the Depression, Anxiety and Stress Scale (DASS) were administered prior to commencement in the program and re-administered by telephone interview at 5-month followup. Four exercise adherence measures were completed: attendance, exercise stress test, self-report ratings and a 7-day activity recall interview. There was a 46% adherence rate for MI patients during the hospital based CEAP. Of those individuals who completed CEAP, 91% obtained functional improvement on the exercise stress test. For the 38 patients …
