Relative muscle activities (%MVIC) during bridging exercises.

Joint angle	60º	90º	120º	F	p	partial η2
Muscle	Mean ± SD	Mean ± SD	Mean ± SD
Rectus abdominis	58.58 ± 11.83	57.05 ± 14.65	56.70 ± 15.75	0.821	0.447	0.039
Rectus femoris	45.30 ± 13.79	45.56 ± 13.57	46.25 ± 15.03	1.385	0.275	0.127
Biceps femoris	69.56 ± 17.81 a	45.76 ± 13.65 b	34.36 ± 13.41 c	31.994	0.000*	0.670

SD: Standard deviation. MVIC: maximum voluntary isometric contraction.

^a Significantly (p < 0.05) different when compared to 90º and 120º.

^b Significantly (p < 0.05) different when compared to 60ºand 120º.

^c Significantly (p < 0.05) different when compared to 60º and 90º. Effect size (partial η²): small = 0.01, medium = 0.06, large = 0.14.
