Which Exercise is Best for you?

Image
By
Exercise and diet are the two most important pillars of good health, and both have as many options and controversies as there are people to give advice on them.  Choosing an exercise regime that fits your specific requirement could be a good starting point for a long term investment in well-being.

 You first need to take stock of your current status and then your requirements.

How do you assess your present physical state? Start with the following:
  1. How old are you?
  2. Do you have any medical problems (heart, knees, anaemia etc)?
  3. Are you a strong willed person who can go it alone or do you need company and entertainment?
  4. What are your constraints (no playground, unsafe roads, no gym nearby etc) 

The role of Age:
In general, the younger the age, more vigorous should be the exercise. A 16 year old, for instance, should play a vigorous out-door game, sprint and run, undertake long distance cycling and so on, but a 60 year old would have to choose from other milder options.
A quick reckoner for cardio-vascular exercise that takes age into account is to target a heart rate of 60% of the maximal heart rate (MHR).

Apply this formula to decide how vigorous your exercise should be: Subtract your age from 220. That gives you the MHR for your age. Now target a heart rate that is 60% of that, and keep on for 30 minutes.
For example, for a 20 year old youth, the MHR is 200. He should undertake vigorous exercise such as running, so that his heart rate reaches 120 (60% of 200). For a 50 year old man, the MHR would be 170, and the heart rate should reach around 100 per minute.

Warming up.Give yourself 5-10 minutes of gradual warming up before you push your heart rate up. This is especially important for people who are above 40 years and who are getting started on an exercise regime.

How to calculate your heart rate while exercising? Most treadmills have a meter that tells you. There are special gadgets that you can wear on your wrist for detecting heart rate. Another simple way is to sense “palpitations” and pant while taking your brisk walk for example.

Cooling down is just as important as warming up. After your 30 minutes of gentle panting and palpitations are over, reduce your speed and taper off the speed gradually, allowing your body to cool off over 10 minutes.

Medical Problems
Exercise is not forbidden for those who have medical problems, but have to be specially tailored to their needs and constraints. An elderly patient with chronic heart failure may, for instance, be able to take just a slow walk for 10 minutes as advised by his cardiologist. Those with creaky knees find it difficult to run on the treadmill as the brunt of their excess weight makes their lower joints cry more. They might do well with “rowing” exercises that spares the knees. Your doctor and a good gym instructor can help you choose the right form for you.

If you have now decided to start with exercise and set your goals, watch this space next week for helping you choose your exercise regime.

How do you like your Tea?

By
The way we drink our tea may not only reflect our taste and style, but our health as well. Tea drinking is around 4700 years old and had its origin in China. Leaves of the shrub Camellia sinensis (tea plant) were in use at that time as a remedy for wounds and diseases. With the legendary emperor Shenong brewing and drinking its extracts, tea drinking became a popular habit in this part of the world. The British, impressed with the brew and the customs that go with drinking it in China and Japan, tried to emulate and evolve a tea-drinking custom of their own, and soon “tea-time”became a familiar term across the globe. Every home or cafe seems to have its own flavour. The north Indian variety of “chay” is a glass of hot creamy milk (more cream as it gets more “special”) with lots of sugar and a lacing of  “tea liquor” of strong tea that grows on lower heights (Assam, Nilgiri, Sri Lanka etc). In contrast, the Chinese and Japanese prefer light green or jasmine tea without a drop of mi...

Food Fads in Liver Disorders

By
In an attempt at trying to do well to those they love, spouses and parents often enforce diets on patients of liver diseases that often turn out to be detrimental. The commonest food fad is pale insipid boiled cabbage being doled out to nauseous patients suffering from hepatitis that makes them puke even more.  The liver, in a way, is a buzzing manufacturing unit that requires lots of energy to keep its multiple functions going. And it derives all this from the food we eat. During disease, such as during an attack of jaundice, when many of the liver cells get killed, the liver attemptsdamage control by trying to regenerate quickly. For its cells to multiply however, it requires a generous supply of energy that comes from carbohydrates, and protein, the building block for its cells and tissues. Boiled green vegetables unfortunately have neither of these. Hence the situation often progresses to that of a starved liver unable to recuperate due to cut-off food suppl...

Colas have No Class

By
Cola drinks, once a symbol of American upmarket style, is now to be found perched mainly on the shelves of road-side ‘paan walas’ and local grocers. True, there still are Americans who drink more colas than water, and consume an average of 2 bottles per day of the tangy fizzy dark drink, but it has clearly fallen in stature as offering it to visitors or serving it at parties is no longer elegant. Premiere schools in Lucknow such as La Martiniere College for girls have shunned colas from their canteen for the last 4 years. The story started with extensive campaigns by HOPE Initiative (Health Oriented Programs and Education) in 2005 creating awareness among the bright students about the long term harms of cola drinks. A heated debate followed in which the rights of an individual student  was pitched against the hazards of allowing gullible youngsters to be enticed by aggressive marketing to gulp colas and fall sick. The intelligent and alert La Marts students dcided on ...
