Recent research conducted by the Norwegian University of Science and Technology, found that four-minute bursts of vigorous physical activity three times each week could elevate oxygen intake levels as well as lower blood pressure and glucose levels. The scientists noted that regular exercise training improves maximal oxygen uptake (VO2max), but the optimal intensity and volume necessary to obtain maximal benefit remains to be defined. A growing body of evidence suggests that exercise training with low-volume but high-intensity may be a time-efficient means to achieve health benefits. A single session of strenuous physical activity performed three times every week may be a time-efficient strategy to improve fitness and lower blood pressure in healthy middle-aged people who were inactive in the past, according to the results. Healthcare experts recently indicated that long, high endurance exercise may produce risks for physically unfit individuals. Therefore, this method of working out could help create a safer way of maintaining personal fitness. A previous report by the Centers for Disease Control and Prevention (CDC) showed that only 20% of Americans are getting sufficient exercise. Although this research is controversial, it is encouraging to know any form of exercise is a start and starting with low expectations may be an easier way to be motivated and more successful in an exercise regimen. Exercise is key in post bariatric surgery (lap band, gastric sleeve, gastric success). Thousands of patients have been able to keep the weight off with a disciplined, consistent exercise program.
