UNLABELLED The criterion variables were total weight lifted (Wttot ) determined separately for women and men during BC and KE, and blood lactic acid concentration ([Hla]) determined for a combined female ( N = 10) and male ( N = 10) subset during BC. Subjects performed three separate sets of 4, 8, and 12 repetitions for BC and KE at 65% one-repetition maximum. Rating of perceived exertion for the active muscles (RPE-AM) was measured during the mid and final repetition and RPE for the overall body (RPE-O) during the final repetition. : For both female and male groups across the three sets: (a) RPE-AM ranged from 3.6 to 8.2 for BC and 5.1 to 9.6 for KE and (b) RPE-O ranged from 2.4 to 6.7 for BC and 4.2 to 7.6 for KE. Positive linear regressions ranged from r = 0.79 to 0.91 ( P < 0.01) between Wttot and RPE-AM (mid), RPE-AM (final), and RPE-O for both BC and KE in both sex groupings. A positive ( P < 0.01) linear regression was found between [Hla] and RPE-AM (final) (r = 0.87) during BC. RPE did not differ between women and men at any measurement point within each set for BC and KE. RPE-AM (final) was greater ( P < 0.01) than RPE-O in the three sets of BC and KE. CONCLUSION Findings provided concurrent validation of the OMNI-RES to measure RPE for the active muscle and overall body in young recreationally trained female and male weight lifters performing upper- and lower-body resistance exercise.

PURPOSE Concurrent and construct validity of the OMNI-Cycle Scale of Perceived Exertion were examined using young adult women and men (18-32 yr). METHODS Concurrent validity was established by correlating OMNI-Cycle Scale ratings of perceived exertion (RPE) with oxygen consumption (.VO2) and heart rate (HR) responses to a load-incremented cycle ergometer protocol. Construct validity was established by correlating RPE derived from the OMNI-Cycle Scale with RPE from the Borg (6-20) Scale. RPE, .VO2, and HR were measured during each exercise stage. RESULTS The range of exercise responses across the incremental test for the female and male groups was .VO2 = 0.92-2.74 L.min-1, HR = 107.2-167.2 beats.min-1, and OMNI Scale RPE-Overall, RPE-Legs, and RPE-Chest 1.0-9.1. Correlation/regression analyses indicated that RPE-Overall, RPE-Legs, and RPE-Chest distributed as a positive linear function of both .VO2 and HR (r = 0.81 to 0.95; P < 0.01). Undifferentiated and differentiated RPE-OMNI Scale distributed as a positive linear function of RPE-Borg Scale (r = 0.92 to 0.97; P < 0.01). ANOVA indicated that OMNI-Cycle RPE-Legs was higher (P < 0.01) than RPE-Chest at each exercise stage for both genders. CONCLUSION Concurrent and construct evidence supports use of the OMNI Scale by adult women and men to estimate RPE during cycle exercise.
