Table 1.  The test-retest reliability of the combined test procedure for the estimation of anaerobic threshold (AT) and maximal aerobic power (VO2 max). Results from test 1 (t1) and test 2 (t2) are reported from the 20 recreationally active subjects. These parameters were used to pre-define acceptable protocol limits of (error) agreement for the subsequent soccer observations. Results are expressed as mean (ąSD).
