Portable system for progressive aerobic cardiovascular endurance run test and method thereof

Portable system for the progressive aerobic cardiovascular endurance run test of a subject, comprising:

• an interface configured for receiving input data from a user, sending instructions to a controller, and displaying data;
• a controller configured for receiving instructions from the interface, controlling a plurality of light emitters, and sending data to the interface;
• and,
• a variable length strip defining a length of the running path and connected to the controller comprising a plurality of light emitters for emitting a light signal to the subject;
• wherein the variable length strip is rolled up in a coil;
• wherein the input data are the test parameters of the progressive aerobic cardiovascular endurance run test and the lap counts at each stage,
• wherein the light signal is a light pattern that, at a pre-determined pace, changes a state of a light emitter in the sequence of the running direction;
• wherein the input data are the parameters of the progressive aerobic cardiovascular endurance run test are chosen from the following list:
• duration of the test, pre-determined pace to be met, number of subjects running, length of the test.
