Based on research conducted at the Institute for Aerobics Research in Dallas, Texas, more than 13,000 healthy men and women were given examinations and tests in order to assess their fitness levels. The first test was a preventive medical examination and the next was a maximal treadmill exercise stress test. When the individuals were tested, no one displayed any sign of cancer or heart disease. This study lasted 8 years, and 240 men and 43 women died. The results of the study revealed interesting statistics. The lower the death rate from cancer and heart attacks, the higher an individuals initial fitness level is. High fitness athletes were not at any lower risk of death versus people with average fitness levels. Findings proved that there was a good improvement among individuals fitness which provided them health benefits. If people simply walked 30 minutes a day, their mortality rate would decrease. The main factor the researchers stressed in the study was that health benefits of physical activity can be achieved at moderate levels of exercise.
I found this study interesting because a lot of people believe you will live longer if you exercise at high levels of fitness. This study proves that moderate levels of fitness will suffice your health benefits. Fitness only benefits people with longer healthier lives.
