- Abstract
With an increase emphasis in society on technical achievements, exercise is not a priority or part of daily life. As such, core muscles are weak and back injury is becoming a national health care problem in the United States. In the present investigation, the subjects were 5 males and 4 females whose average age was 26.5+/-4.5 years. These subjects evaluated a new type of exercise program. The exercise program was on video tape (Crunchless Abs) and lasted approximately 20 minutes. The exercises were specifically designed to exercise the superficial and deep core muscles together. Abdominal crunches only exercise one or two muscle groups. During the exercise, muscle use was evaluated using the electromyogram and 2 D ultrasound to evaluate which muscles are contracting. Seven exercises were examined here. For the 7 exercises examined, there was significantly more muscle use and greater work than for abdominal crunches. More importantly, muscle use included deep and superficial muscles and engaged many different muscles in differing areas of the core of the body. Work was as high as 622% that of an abdominal crunch with average work of 312% that of an abdominal crunch with the Crunchless Abs video. Thus, this program is a better workout than that seen with crunches.
