Anaerobic exercise uses about 10 times more energy than aerobic exercise, and you have more "fuel" available for aerobic exercise. Anaerobic exercise also produces lactic acid, which is what causes your muscles to burn.
It's more than possible; it's a good idea. Exercise during your period helps relieve cramps and bloating.
This type of exercise, during which the body's oxygen need exceeds the lungs' ability to replenish it is called anaerobic exercise -- literally, 'without air.' Exertion of longer duration, during which the body is able to sustain the energy output (and the lungs have the capacity to provide the necessary oxygen for a longer period of time) is known as aerobic exercise.
If you have time for some exercise on a daily basis, go for it! It's good for you. Now, if you are doing strength training/lifting weights, you should not work the same muscles on consecutive days. This is because when doing working your muscles intensely (or "anaerobically"), your muscle fibers actually break down somewhat. These fibers then regenerate and become even stronger, but the rest period between workouts is what allows this to happen. P.S. - Don't exercise when you're injured, either.
You will obviously have less energy. I have experimented the effects of eating and not eating before exercise. I concluded that when I have something to eat before exercise (not necessarily right before exercise) I am able to run for a longer period than when I do not consume anything.
A longer pendulum has a longer period.
You need exercise, period!
The period of time after you stop exercise is called the cool down time.
Fu!
Just exercise more.
Plank exercise is an isometric exercise that strengthens the core by holding a difficult position for a long period of time.
Yes, if your period is around its due date. If it isn't time and exercise seems to cause you to start, it isn't exactly normal.
The period of a pendulum is directly proportional to the square root of its length. As the length of a pendulum increases, its period increases. Conversely, if the length of a pendulum decreases, its period decreases.
