When trying to lose weight, the timing of exercise plays a key role, recent findings suggest.In a study of 375 adults who have successfully maintained weight loss and who engage in moderate-to-vigorous intensity physical activity, most reported consistency in the time of day that they exercised, with early morning being the most common time.The study also found that being consistent in the timing of physical activity was associated with higher physical activity levels, regardless of whether people exercised consistently during the morning, afternoon, or evening.The findings were published in the Journal of Obesity.“Our findings warrant future experimental research to determine whether promoting consistency in the time of day that planned and structured physical activity is performed can help individuals achieve and sustain higher levels of physical activity,” said senior author Dale Bond.Exercise strengthens your heart and improves your circulation. The increased blood flow raises the oxygen levels in your body. This helps lower your risk of heart diseases such as high cholesterol, coronary artery disease, and heart attack. Regular exercise can also lower your blood pressure and triglyceride levels. Along with diet, exercise plays an important role in controlling your weight and preventing obesity. To maintain your weight, the calories you eat and drink must equal the energy you burn. To lose weight, you must use more calories than you eat and drink. Exercise stimulates your body to release proteins and other chemicals that improve the structure and function of your brain.Regular exercise may lower the risk of erectile dysfunction (ED) in men. For those who already have ED, exercise may help improve their sexual function. In women, exercise may increase sexual arousal. “Exercise increases energy levels and increases serotonin in the brain, which leads to improved mental clarity,” says Atkinson, director of program development for Cooper Ventures, a division of the Cooper Aerobics Center in Dallas.All that makes for a more productive day.”It is clear that those who are active and who exercise are much more productive at work,” says Todd A. Astorino, assistant professor of kinesiology at California State University- San Marcos. Improved productivity not only makes you a better worker, it makes things better for everyone in the workplace. Companies with less wasted work hours and less sick time end up with lower health care costs — and an improved bottom line, Astorino says.
