No Gain Without Pain !!!

If pottering about the house is your idea of fitness, you have got it all wrong, says Norbert Rego

YOU walked to the railway station this morning, marched up the escalators, and when you get back home, you’ll walk your pet. Is this sufficient to remain fit? Sadly no, says research.

“Light exercises do not provide the required cardiovascular reserve. One has to indulge in a variety of fitness programmes — treadmill, swimming, light running and jogging. These exercises decrease fat, enhance and improve circulation, increase muscle mass, regulate body metabolism and keep a person fit, physically and psychologically, says Dr Sanjeev Jain, consultant, Dr L H Hiranandani Hospital, Mumbai.

Keeping fit generally means having a good exercise tolerance so that one does not tire easily. The main systems in the human body involved in day-today functioning and directly affected by exercise are the cardiovascular system (heart for pumping blood) and pulmonary system (lungs for supplying adequate oxygen for energy). A healthy cardio-respiratory system leads to a well-functioning gastrointestinal system (stomach, bowels, etc), which is then able to absorb the required nutrients and supply the body with proper nourishment. This leads to a healthy mind and body.

“To improve efficiency of the cardio-respiratory system, one needs aerobic exercise, ie, a workout which increases exercise tolerance. However, to be effective, it should be done at a pace that will surprise the body and force it to keep up with the higher level of activity. It is ideal to push heart rate up to 80 per cent of the maximum advisable limit for your age and health, after seeking medical advice. This will increase the overall Basal Metabolic Rate (BMR) , and make the body more efficient,” says Dr Kaushal Malhan, consultant, Wockhardt Hospital, Mumbai.

“To remain fit, one has to keep all the joints moving and keep muscles toned to support skeletal system. This improves posture, controls muscular and joint aches, improves skin circulation,” adds Dr Jain.

A research, published in the Journal of Epidemiology and Community Health, found that women who did more than eight hours a week of heavy housework were actually slightly more likely to be overweight than those who did none — and no amount of vacuuming, scrubbing and cleaning lowered resting heart rate, which is an indicator of enhanced aerobic fitness.

Since we all have different levels of fitness, it's impossible to prescribe any single activity or target heart rate as suitable for all. There is evidence that brisk walking protects women from diabetes and heart disease, but for most middle-aged men, walking simply isn't challenging enough. Men who want to reduce their risk of diabetes and heart disease should consider jogging, circuit training, running or competitive sports.
