Another nuance for the term "jolly horse" is used to describe simple painful muscle cramps in the leg or foot, especially those that follow strenuous exercise.

Jeffery D. Black knew the formula for staying alert at business meetings on the road: follow a disciplined diet, stretch or exercise and get a good night's sleep.

Exercise Associated Muscle Cramps (EAMC) is defined as cramping (painful muscle spasms) during or immediately following exercise.

Using vitamin C in amounts of 600 mg to 1 gram per day before heavy physical exercise, such as a marathon, might prevent upper respiratory infections that sometimes follow heavy exercise.

Taking bromelain orally, immediately following intense exercise, does not seem to delay onset of muscle soreness and has no effect on pain, flexibility, or skeletal weakness.

A study published in the Journal of Applied Physiology (online May 8, 2008) suggests that, when athletes ingest both carbohydrate and caffeine following exhaustive exercise, their glycogen is replenished more rapidly.

During the rest that follows exercise, potassium levels tend to rise, and that in turn can disturb the horse's ion channels.

To compensate for this glycogen reduction, athletes will often take in a large amount of carbohydrates in the period immediately following exercise.

Eight subjects were asked to follow a "brain healthy" diet, relaxation, physical, and mental exercise (brain teasers and verbal memory training techniques).

Or blood-tinged urine may follow strenuous exercise like a long run or triathlon.
