BUT...
<30% of physicians in the US discuss exercise with patients!
AND
The most influential factor for people to get involved with regular exercise programs is physicians' recommendation for exercise.
The ideal prescription addresses frequency, intensity, duration, and type of exercise. It's got to be individualized and id what people enjoy.
The American College of sports Medicine recommended adults spend 30 minutes/day doing moderately intesne activity most days of the week in 1993. But new guidelines from the Institute of Medicine suggest 60 minutes every day to avoid weight gain.
Man...that's like an hour a day! For most people I know, we spend a lot of time sitting. So, I'm trying to do well in school because I want to really know my stuff and be the most competent physician I can, but that means...I spend a lot of time sitting in class, home, cafe, whatever...but I'm sitting while I'm at my computer going through powerpoints, looking things up, checking email, being distracted from work ...all in all...without really moving anything. When I start to think about all the lectures I have to go through and the time it takes...well, there just doesn't seem to be enough time, so how am I supposed to set aside 1 hr plus to work on moving my body?
Well, EXERCISE is really important. and here is why!
Every good exercise program should include (1) aerobic exercise (2) strength training and (3) flexibility exercise.
(1) aerobic exercise: it works your heart plus it increases caloric consumption (important in weight control and fat loss)For this effect: maintain a good target heart rate range for 20-30 minutes 3 time per week.
--> Target heart rate= 50-75% of 220-(your age) beats per minute.
(2) strenght training: resistance exercise builds muscle tone and strength by progressiviely overloading your muscle tissue. It also affects bone, ligaments and tendons so it's good for osteoporosis prevention, injury prevention, and weight/fat control.
(3) flexibility: strethcing reduces the likelihood of muscle strain and injury, prevents muscle soreness, helps maintian mobility and functionin arthritic joints, and improves muscle elasticity (after a brief aerobic warm-up). For this effect: do slow, static stretches held for 15-20 seconds.
Exercise is safe and benefits people of all ages, you just need to make sure do have a regular program that is individualized for you.
