An overly contracted low back muscles combined with a weak abdominal muscles are the typical cause of back pain. To overcome the problem, the abdominal muscles need to be physically stronger in order to be free from pain. Thus, this study was carried out to determine the intensity of abdominal muscle contraction between crunch performed traditionally and on stability ball, so that it can be used to prescribe a time efficient and cost effective mode to improve several health and performance parameters. Fifteen sedentary female university students with no previous history of back pain or injuries were recruited for the study. Muscle activity was assesed using surface electromyography (EMG) recorded using Delsys DE-2.3 differential surface electrodes during crunch performed traditionally and on stability ball. EMG electrodes were placed in the four tested regions upper rectus abdominis, lower rectus abdominis, external oblique and transversus abdominis. The result of this study showed that of the four muscles tested, only two muscles elicited significant difference on the intensity of contraction when performed on stability ball compared to the traditional crunch. There were significant difference existed between transversus abdominis (21.26 + 4.44 mV) and lower rectus abdominis (16.78 + 8.14 mV) performed traditionally and on stability ball. It was discovered that abdominal crunch performed on unstable surface recruited more muscle than traditional crunch. This is because in order to gain balance, the body must maintain muscular control, balance, coordination and proprioception. In order to gain core stability development, the core must be challenged to elicit the degree of cocontraction. The challenge can be provided by stability ball thus, produces desirable strength of abdominal muscle. 2013-01 Thesis https://ir.uitm.edu.my/id/eprint/16421/ https://ir.uitm.edu.my/id/eprint/16421/1/TM_NURUL%20FIZAN%20SIDEK%20SR%2013_5.pdf text en public mphil masters Universiti Teknologi MARA Faculty of Sport Science and Recreation Md.
