Table 1. External load variables outcomes and rate of perceived exertion of the different squatting conditions.
Condition Kg at standing position Number of Repetitions RPE
1 (10RMWP) 95.95 ± 17.88 [87.58-104.32] 10.00 8.55 ± 0.88 2,3,4,6 [8.14-8.96]
2 (5RMWP) 108.60 ± 20.24* [99.13-118.07] 5.00* 7.75 ± 0.72 1,4,5,6 [7.41-8.09]
3 (9RSMWP) 95.95 ± 17.88 [87.58-104.32] 9.00 7.55 ± 0.99 1,4,5,6 [7.09-8.01]
4 (10REB) 95.95 ± 17.88 [87.58-104.32] 10.00 6.50 ± 1.24 * [5.92-7.08]
5 (XRMEB) 95.95 ± 17.88 [87.58-104.32] 18.40 ± 4.86* [16.13-20.67] 8.65 ± 0.93 2,3,4,6 [8.21-9.09]
6 (XRMEBSP) 119.65 ± 22.86* [108.95-130.35] 13.45 ± 3.84 * [11.65-15.5] 9.10 ± 0.55 * [8.84-9.36]
Note: 95.95 kg, 108.60 kg, and 119.65 kg corresponded to approximately 75%, 85% and 94% of participants’ 1RM, respectively. A 20 kg barbell was used in all the conditions.*: Statistically significant difference compared to the rest of the conditions.1, 2, 3, 4, 5, 6: Significant difference with the condition 1, 2, 3, 4, 5, or 6. Values are expressed as mean ± standard deviation (SD) [95% Confidence Interval]. RPE: rate of perceived exertion; RMWP: repetition maximum with weight plates; RSMWP: submaximal repetitions with weight plates and with the same weight used for the 10RMWP condition; EB: elastic bands; REB: submaximal repetitions with EB with the same weight used for the 10RMWP condition; XRMEB: Repetitions to failure with elastic bands with the same weight used for the 10RMWP condition; XRMEBSP: repetitions to failure with EB and loaded with the same weight used for the 10RMWP condition and placed immediately above the knee sticking point.
