20.500.12556/RUL-137231 Electromyographic comparison of an abdominal rise on a ball with a traditional crunch We propose a new exercise, the abdominal rise on the ball, to replace the traditional crunch in exercise programs. The aim of this study is to compare the activity of the abdominal muscles when performing an ARB with the same activity when performing a traditional crunch. Twenty healthy adults participated in the study. Surface electromyography (EMG) was recorded from the upper and lower rectus abdominis (URA, LRA), internal oblique (IO), external oblique (EO), transversus abdominis (TrA), and erector spinae (ES). EMG values were normalized to maximal voluntary isometric contraction. A paired t-test, nonparametric Wilcoxon test and correlation coefficient were used for statistical analysis. The normalized EMG values of EO, TrA and ES, were statistically significantly higher during the abdominal rise on the ball compared to the traditional crunch, while URA, LRA and IO were significantly lower during the abdominal rise on the ball compared to the traditional crunch. TrA, EO and IO are sufficiently activated during an abdominal rise on a ball, so the exercise could be deemed effective for strengthening these muscles. strength exercise muscle recruitment EMG abdominal muscles vadba za moč pridobivanje mišic EMG trebušne mišice true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-08 07:58:49 2022-06-08 07:58:51 2022-09-15 04:14:49 0000-00-00 00:00:00 2022 0 0 9 str. iss. 5, art. 1979 Vol. 22 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.01 1424-8220 10.3390/s22051979 99970051 sensors-22-01979.pdf sensors-22-01979.pdf 1 12938F9125C122AD695B4D406C1EDB97 fe4a53b6e5928caea61564af6c037705e6c419c02d6b1bb76321ece9a6617479 300dac2a-e6f0-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157112 https://www.mdpi.com/1424-8220/22/5/1979 0 e9786250-e6ef-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157111 Fakulteta za šport 0 0 0
