Number of calories burnt while exercising is key to fitness
PakTribune.com - Pakistan, July 17 2005 -- ISLAMABAD, July
18 (Online): Concentrating on the number of calories burned while exercising
is our way to fitness.
According to a recent Harvard study, burning an extra 700-2,000
calories a week through some form of dynamic exercise garners significant
health benefits.
The amount of calories burned during a workout depends
on a personal weight, and the intensity and duration of the activity.
The Harvard Heart Letter suggests finding benchmarks for various activities
based on your weight.
Here are a few benchmarks for a 155-pound person:
*Walking briskly (at 4 miles per hour) for 30 minutes burns
150 calories.
*Heavy cleaning for 45 minutes burns 250 calories.
* An hour of singles tennis burns 300 calories.
The intensity of the exercise, however, does not make a
difference in the number of calories burnt.
Brief sessions of an intense activity can burn the same
number of calories as longer or more frequent sessions of a less intense
one.
End.
