Fatigue loading protocol (haversine waveform at 1 Hz). A diagnostic test is applied (diag1) for 420 cycles between 1 N and 15 N. Fatigue loading then follows for x cycles between 1 N and 40 N (x = 5, 100, 500, or 7200). A second diagnostic test (diag2) is then applied for 120 cycles, followed by 45 min recovery, then a final diagnostic (diag3) test.
