Skinfold measurements are most accurate when taken

before exercise.

Explanation:

Skin fold is a measure of the thickness of two layers of skin and the adjacent subcutaneous fat. Several skinfolds can be evaluated alone or together. Among these, we can mention the tricipital, bicipital and calf skin folds, indicating peripheral fat, and the subscapular and suprailiac folds, indicating central fat. Due to the existence of a relationship between subcutaneous fat and total body fat, the sum of several skin folds can be used to estimate total body fat.

The validity and reliability of skinfold measurements are influenced by the evaluator's ability, the type of adipometer, the factors of the individual evaluated and the equation used to estimate body fat. In addition, the practice of exercise can interfere with these measures, for this reason, it is preferable that the measurement be made before the practice of exercises.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
