From Lifespan to โHealth-spanโ: Use the New Year to Focus on Both Health and Fitness
Fitness includes several components such as cardiovascular endurance, strength training, and mobility/flexibility. These are non-negotiables for continuing to live throughout your later years with your independence and ability to move and socialize still operating normally. Instead of just thinking about living longer, letโs use the start of a new year to focus on getting healthier, so we live better. More than any other time each year, the New Year is a popular time to focus on a โstart fresh.โ Temporal landmarks like New Year's Day, Mondays, birthdays, or the change of seasons are standard starting lines for many of us when we have a goal to work towards and bad habits to break. A New Focus on Fitness โ Science Says Fitness Matters (Even More than Weight) A recent study published in the British Journal of Medicine, Cardiorespiratory Fitness, BMI, and Mortality: A Systematic Review and Meta-Analysis, shows that, regardless of body weight (obese, overweight, or normal), fitness matters more for all-cause mortality. They measured weight, BMI, and fitness of six groups: normal weight โ fit, normal weight โ unfit, overweight-fit and overweight-unfit, and obese-fit and obese-unfit. Their findings: The analyses revealed that individuals classified as fit, regardless of their BMI, did not have a statistically significantly higher risk of cardiovascular disease or all-cause mortality compared to normal weight-fit people. At the same time, all unfit groups across different BMI categories exhibited a two- to threefold higher risk of cardiovascular disease and all-cause mortality compared to their regular weight-fit counterparts. About Body Mass Index (BMI) โ Now, you may be saying, but BMI is flawed! Sure. BMI is not the best indicator for distinguishing normal weight, overweight, and obesity because it is simply a height-to-weight ratio that does not account for differences in body fat/muscle composition, age, sex, or other factors. Before you discredit this entire study because of the BMI issue, remember that it measured fitness levels among people of different sizes. Some had more muscle and were considered fit in the overweight/obese group, while others were deemed unfit in the normal weight group. Still, BMI helps place people of differing sizes (height and weight groups) and focuses on measuring each group's fitness. In the end, fitness matters more than BMI, so the goal is to exercise, get in shape, build muscle, and lose fat.
