Below is a few questions I get asked from time to time. You'll most likely be asked these questions when you become a nurse. As time progresses, I hope to add more questions and answers.
"Is my blood pressure supposed to rise when I exercise?"
Yes, and the increase depends on the type of exercise your doing. If your doing an exercise that uses smaller muscle groups, like the arm ergometer, then you'll have a higher blood pressure rise than, for instance, the treadmill which uses larger muscle groups. But with any machine you use, your blood pressure is going to increase to supply the amount of oxygen and nutrients your muscles need to do the work. If you feel dizzy or lightheaded while exercising that might be a sign that your blood pressure is too high (or too low) and it would be time to slow down or stop.
"For weight control, is it better to jog 1 mile or walk 2 miles?"
For burning calories, the total distance covered is the key point: walking 2 miles. But if the question was whether to walk for 10 minutes or jog for 10 minutes, then jogging for 10 minutes would be the better option because you cover more total distance in jogging than you do walking for 10 minutes. If you can't jog for 10 minutes straight, maybe walk for 2 minutes and then jog for a minute and repeat. Over time, slowly increase your jogging time and decrease your walking time. So again, the key is total distance.
"Should I drink water or Gatorade when I work out?"
If your on a sodium restricted diet, then water is definitely the best way to go. But in general, if your exercising for less than an hour then water is best. If your exercising for greater than an hour at a high intensity with great amounts of sweating, then gatorade is best. That's because gatorade is better at replenishing electrolytes and energy stores that are lost through sweat during long duration, high intensity exercise.
"How many calories are in a mile?"
It's roughly 100 calories per mile. Or for a little more accuracy, simply multiply your body weight in pounds by 0.74 to estimate the calories burned in a mile. (Example: 165 lbs x 0.74 = 122 calories burned/mile)
"How much exercise is needed to lose weight?"
The optimal exercise energy-expenditure goal appears to be 1,500-2,000 calories or more per week, or about 150-400 calories per day. For walkers, this approximates 10,000 steps daily. If your using exercise machines, have a small pad of paper with you and make a note of the amount of calories you burn after every machine you use. At the end of your routine, add them up. Try to slowly get within the 400 burned calories per day. But another thing that's just as important as exercise (if not more) is your diet and the amount you eat. If your still eating a lot of sweets or having huge meals, your going to replace the calories you burned with excess calories you ate and as a result, no weight loss occurs. So lower your food portion sizes!
