OBJECTIVE To compare the effect and sustainability of 6 months combined aerobic/strength training vs aerobic training alone on quality of life in women after coronary artery by-pass graft surgery or myocardial infarction. DESIGN Prospective, 2-group, randomized controlled trial. PARTICIPANTS Ninety-two women who were 8-10 weeks post-coronary artery by-pass graft surgery or myocardial infarc...

PURPOSE/OBJECTIVES To test the effects of aerobic and resistance exercise on changes in bone mineral density (BMD) in women newly diagnosed with stage I-III breast cancer receiving chemotherapy. DESIGN Randomized clinical trial. SETTING Two National Cancer Institute-designated cancer centers in metropolitan areas. SAMPLE 66 women with stage I-III breast cancer beginning adjuvant chemother...

Plasma volume (PV) expansion by endurance training and/or heat acclimatization is known to increase aerobic and thermoregulatory capacities in humans. Also, higher erythrocyte volume (EV) fractions in blood are known to improve these capacities. We tested the hypothesis that training in a hypobaric hypoxic and warm environment would increase peak aerobic power (VO(2)(peak)) and forearm skin vas...

In situations where the accumulation of internal heat limits physical performance, enhanced heat extraction from the body should improve performance capacity. The combined application of local subatmospheric pressure (35-45 mmHg) to an entire hand (to increase blood volume) and a heat sink (18-22 degrees C) to the palmar surface were used to draw heat out of the circulating blood. Subjects walk...

Traditionally, organisms responsible for major biogeochemical cycling processes have been determined by physiological characterization of environmental isolates in laboratory culture. Molecular techniques have, however, confirmed the widespread occurrence of abundant bacterial and archaeal groups with no cultivated representative, making it difficult to determine their ecosystem function. Until...

Design We aimed to evaluate the effect of progressive resistance training on cardiorespiratory fitness and muscular strength in coronary heart disease, when compared to control or aerobic training, and when combined with aerobic training. Secondary aims were to evaluate the safety and efficacy of progressive resistance training on other physiological and clinical outcomes. Methods and results E...

Obesity is known to be associated with variety of complex diseases including hypertension, cardiovascular disease, diabetes, affective disorders, and some cancers. The heterogeneous genetic (G) and environmental (E) conditions of human populations impart considerable difficulty for uncovering a common etiology between complex disease and their associated risk factors. Development of animal mode...

Objective: Exercise and nutrition as life style modification strategies for the prevention and control of diabetes are considered. The aim of present study was to assess the effects of saffron consumption and aerobic exercises on serum levels of Heart-type fatty acid binding protein (HFABP) and Troponin T in type2 diabetes (T2DM) patients. Materials and Methods: This study was a quasi-experime...

QUESTION One of my patients asked if she could buy human milk on the Internet to feed her infant if the need arose. Is using donated breast milk from the milk bank safer than buying it online? ANSWER The World Health Organization and the American Academy of Pediatrics recommend the use of donated breast milk as the first alternative when maternal milk is not available, but the Canadian Paedia...
