Figure 1

Changes in primary motor activity (C3, CZ, C4) across six sets. By Set 4, the high volume protocol (VOL, ten repetitions per set at 80%) was significantly higher than all other protocols and its first three sets. Please note that the high force protocol (FOR, three repetitions per set at 95% 1RM) begins as a low negative value and is significantly different from all protocols at Set 1. By Set 6, FOR is significantly different from its first four sets and only significantly different from the VOL protocol. Pairwise differences are indicated in the form X:Y, indicating Reference Protocol: Significantly Different Protocol. “F” indicates the FOR protocol, “V” VOL, and so forth. In a given protocol, “1” indicates the value is significantly different from Set 1 of that protocol, “2” from Set 2, and so forth.
