The intensities of yoga and balance exercise were significantly lower than those of resistance and aerobic exercise, but these exercises are effective in improving flexibility and in fall prevention, researchers said.Īmericans and Japanese are increasingly overweight. The most effective exercise is the single-arm stand, 5.6 METs, regarded as a difficult resistance exercise that involves standing up and lying down. Wii fit™ includes yoga, resistance and strength training, balance and aerobic exercises with more than 40 different activities, from push-ups to torso twists to single leg extensions. Golf, bowling, tennis and baseball are 2.0, 2.6, 3.0, and 3.0 METs, respectively. Boxing is the most effective activity to increase energy expenditure, about 4.5 METs, according to the study findings.
Wii sports™ are a collection of five simplified games based on boxing, golf, tennis, bowling and baseball. Some physical activity is better than none. Regular physical activity reduces the risk of many adverse health outcomes. Adults gain the most health benefits when they do the equivalent of at least 150 minutes (2 ½ hours) of moderate intensity aerobic physical activity each week. An adult walking at three miles per hour on a flat surface is expending about 3.3 METs. "The range of energy expenditure in these active games is sufficient to prevent or to improve obesity and lifestyle-related disease, from heart disease and diabetes to metabolic diseases," Miyachi said.Īccording to the American Heart Association's exercise guidelines, light intensity exercise is less than 3.0 METs moderate intensity is 3.0 to 6.0 METs and vigorous activity is more than 6 METs. "Energy expenditure is the most important information to measure the effect of video games," said Motohiko Miyachi, Ph.D., lead author of the study and Project Leader of Project for Physical Activity in the Health Promotion and Exercise Program at the National Institute of Health and Nutrition in Tokyo, Japan. The metabolic chamber method could replicate the conditions under which the participants enjoy the games in their home, because they were free from apparatus used to measure energy expenditure (EE) when playing the game. The open-circuit indirect metabolic chamber consisted of an airtight room (20,000 liters or 15,000 liters). Researchers used a metabolic chamber to measure the energy expenditure of 12 men and women, 25 to 44 years old, as they pantomimed basic moves and motions of these sports and physical activities with motion-sensing controls. The average intensities were distributed over a wide range from lotus focus, 1.3 METs, to single-arm stand, 5.6 METs. METs are metabolic equivalent values, a standard method of estimating energy expenditure. The study, funded by Nintendo™, demonstrated that about one-third of the virtual physical activities require an energy expenditure of 3.0 METs or above, considered moderate-intensity exercise.
