Motor fitness is a more inclusive term than physical fitness.

Physical fitness combines strength, stamina, and cardiovascular reserve. Motor fitness includes these and adds agility, balance, “explosive” power, and speed. This concept has more limited value for the sportsman but approaches an even higher level of general fitness. Because more parameters are measured, these tests tend to become increasingly complex and complicated.

Perhaps the simplest of these is the JCR Test. This is intended to assess basic motor skills such as jumping, chinning, running, and dodging which presumably require power, stamina, speed, and agility.

The J of JCR stands for the vertical jump . This is performed by having the subject stand erect, reaching as high as he can without standing on tiptoes, and making a mark

the wall.

Next, he squats down and then leaps as high as he can—making another mark on the wall. The distance between the two chalk marks is recorded.

The C is for chinning . With palms facing forward, the subject grasps a bar above his head. He then chins himself as many times as possible, making sure that his elbows are straight before each chin. Wiggling, kicking, and jerking are not allowed.

Running accounts for the R in JCR . This is a hundred-yard shuttle run. The subject runs a ten-yard course ten times—back and forth between two walls ten yards apart. His time is then measured in seconds.

In all types of fitness measurements, experts generally deplore self-testing. Unintentionally the subject may count partial movements as complete. Or the ability to time oneself may be askew. However, these objections do not apply to sportsmen provided that they always perform the test in the same manner, under the same conditions, and are measuring for comparison—improvement or deterioration. The sportsman competes only against himself in fitness tests; he is not concerned with what other individuals or other groups can or cannot do. He is checking his own progress.
