Table 3. Comparison of Gluteus maximus (GMax) activation for all exercise variations. Classification of muscle activation is givens as low (0-20% MVIC), moderate (21-40% MVIC), high (41-60% MVIC) and very high (>60% MVIC). Values are given as mean or the average of pooled mean of maximum voluntary isometric contraction percentage (%MVIC) and the standard deviation. Classification Level of activation Exercise Average (%MVIC) 1º Very high Step-Up 169.22 ± 101.47 2° Very high Lateral Step-Up 114.25 ± 54.74 3° Very high Diagonal Step-Up 113.21 ± 43.54 4° Very high Crossover Step-up 104.19 ± 33.63 5° Very high Hex Bar Deadlift 88 ± 16 6° Very high Rotation Barbell Hip Thrust 86.18 ± 34.3 7° Very high Traditional Barbell Hip Thrust 82.37 ± 18.65 (Lower GM: 69.5/Upper GM: 86.7) 8° Very high American Barbell Hip Thrust 73.65 ± 22.98 (Lower GM: 57.4 ± 34.8/ Upper GM: 89.9 ± 32.4) 9° Very high Belt Squat 71.34 ± 29.42 10° Very high Split Squat 70 ± 15 11° Very high In-line Lunge 67 ± 11 12° Very high Traditional Lunge 66 ± 13 13° Very high Pull Barbell Hip Thrust 65.87 ± 23.28 14° Very high Modified Single-leg Squat 65.6 ± 15.1 15° Very high Traditional Deadlift 64.50 ± 41.72 16° Very high Band Hip Thrust 64.2 ± 21.21 (Lower GM: 49.2 ± 26.5/ Upper GM: 79.2 ± 29.9) 17° High Parallel Back Squat 59.76 ± 22.52 18° High Feet-away Barbell Hip Thrust 51.38±17.93 19º High Front Squat 40.54 ± 4.73 20° High Stiff-Leg Deadlift 40.5 ± 18.8 21° Moderate Overhead Squat 39.75 ± 29.91 22° Moderate Sumo Deadlift 37 ± 28 23° Moderate Partial Back Squat 28.16 ± 10.35 24° Moderate Full Back Squat 26.56 ± 12.33
