^aICC: intraclass correlation coefficient (at a 95% CI).

^bHR: heart rate.

^cResting heart rate measurement.

^d1-minute HR after test: heart rate recovery 1 minute after the 3-minute step test.

^eUE strength: upper extremity strength (push-up test).

^fCurl-up test.

^gLE strength: lower extremity strength (wall squatting test).

^hLE flexibility: lower extremity flexibility (sit-and-reach test).

ⁱUE mobility: upper extremity mobility (upper extremity multipattern test).

^jN/A: not applicable; no intraclass correlation coefficient value was calculated because the raw data of the upper extremity mobility test was the percentage of participants, not a continuous variable.
