Regular activity can bring an abundance of benefits to your life. Exercise helps with weight management, cardiovascular health, reducing the risk of some diseases and cancers, regulating blood pressure and improving mood and energy. Activities like rollerblading and running can strengthen leg and core muscles and burn calories. The amount of calories you burn during one session of exercise can depend on a number of factors, including duration and intensity.
Comparing Calories
A 140-lb. individual who rollerblades at a pace of 8 mph can burn approximately 235 calories in 30 minutes, or about 336 calories from running for the same amount of time at a pace of 6 mph. In 30 minutes, a 170-lb. individual can burn about 286 calories from rollerblading at a 10 mph pace, or 408 calories from running at 6 mph.
Variables
The amount of calories you burn during a period of exercise depends on a number of variables. Weight, gender, fitness level, metabolic rate, duration and intensity can all affect your caloric expenditure. To increase your caloric expenditure, increase the speed or duration of your exercise and incorporate incline running or skating.
Heart Rate
The most accurate measure of determining your exercise intensity and caloric expenditure is to measure your heart rate during exercise. Your target heart rate zone is the heart rate range you should aim for while you exercise. For men, this zone is found by calculating the equation (220 - age) x 0.65 and then (220 - age) x 0.85. Women should calculate 206 - (age x 0.88) and then multiply that answer by 0.65 and also by 0.85. Strive to keep your heart rate within this zone during exercise. Increase intensity if your heart rate is below the low-end of the range and reduce intensity if your heart rate exceeds this zone.
Considerations
Speak with your doctor before beginning a new exercise program. Although exercise is an important part of general health and wellness, not all exercises are suitable for all people. Your doctor can help you determine the exercises that are most appropriate for your current health conditions and fitness level.
