One metabolic equivalent (MET) is defined as the amount of oxygen consumed while sitting at rest and is equal to 3.5 ml O2 per kg body weight x min. The MET concept represents a simple, practical, and easily understood procedure for expressing the energy cost of physical activities as a multiple of the resting metabolic rate. The energy cost of an activity(More)
Fitness in the military is a time-honored and unquestionable axiom. Yet, there is limited objective knowledge as to what criteria of fitness are necessary to maintain combat effectiveness during sustained operations and how they should be assessed. The purpose of this study was to design an indoor standardized obstacle course (ISOC) related to specific(More)
BACKGROUND This study was designed to determine the controlled effects of a short-term exercise rehabilitation program on patients with moderate-to-severe left ventricular dysfunction after a recent myocardial infarction. METHODS AND RESULTS Thirty-nine male patients 51 +/- 8 years old with a large anterior myocardial infarction less than 10 weeks old(More)
The purpose of this study was to determine the potential effects on progressive aerobic work while breathing through a new military type chemical and biological (CB) respirator loaded with three different types of purifying canisters. Twelve healthy well-motivated male subjects (mean age 23±3 years) participated in the study. Results indicated that mean(More)
The purpose of this study was to determine if maximum oxygen consumption (Vo(2) max) could be predicted from independent variables measured during the administration of the Canadian Home Fitness Test. Fifty-nine subjects between the ages of 15 and 74 years underwent the fitness test and a progressive exercise treadmill test for the direct determination of(More)
The traditional use of core temperature to assess the thermal effects of clothing has recently been questioned. The purpose of this study was to assess the reproducibility of body temperature in five subjects (mean age, 22.6 +/- 1.5 years) wearing either athletic clothing or a chemical protective overgarment while exercising at 20 degrees C and at 40(More)
The Canadian Forces (CF), concerned with the possible adverse effects of obesity on military performance and image, recently adopted the body mass index (BMI) to monitor excess weight among its personnel. Subsequently, the records of 17,098 CF men (32.0 +/- 8 years) and 2,087 CF women (26.2 +/- 5 years) were examined. Approximately 50% of the men and 25% of(More)
OBJECTIVE To determine the relation between cardiorespiratory fitness, as determined with the Canadian Aerobic Fitness Test (CAFT), and selected risk factors for coronary heart disease (CHD) in a Canadian population. DESIGN Cross-sectional study. On the basis of age-specific and sex-specific national percentile scores, subjects were classified as being in(More)
