The Influence of a personal trainer on self-selected loading during resistance exercise
| Resumo: | The purpose of this study was to compare differences in muscle strength and self-selected 3 resistance training intensities between trained subjects who trained under the supervision of a 4 personal trainer (PT) and those who trained without supervision (WoPT). Twenty-one trained 5 subjects, men (n = 12) and women (n = 9), completed three sessions (separated by 48 hours) in the following sequence: (1st 6 ) self-selected intensity assessment consisting of performance 7 of three sets of 10 repetitions for the leg press, bench press, leg extension, and arm curl exercises with self-selected load; (2nd 8 ) a one repetition-maximum (1RM) test to determine subjects’ maximal strength in the four exercises; and (3th 9 ) a 10 repetition-maximum (10RM) 10 test to determine the maximum load completed for 10 repetitions for each exercise. Self11 selected training loads were significantly higher in PT compared to WoPT for the leg press 12 (by 15.6%), bench press (by 26.6%), leg extension (by 12.1%), and arm curl (by 22.2%) 13 exercises. Self-selected training loads expressed relative to 1RM and 10RM data were 14 significantly higher in PT (49% to 59.5% of 1RM; 62.7% to 77.3% of 10RM) than WoPT 15 (41% to 58.7% of 1RM; 58.7% to 76.2% of 10RM) with largest difference observed in the 16 lower-body exercises. Ratings of perceived exertion (RPE) values were significantly higher 17 in PT compared to WoPT. The results of the present study indicated that supervised 18 resistance training with a personal trainer was advantageous in trained subjects although self19 selected loading was still considerably lower than 1RM and 10RM percentage values. |
