The purpose of this study was to compare electromyographic (EMG) activity of the abdominal muscles between the crunch exercise and five other popular abdominal exercises. Surface EMG recordings of four muscles (upper rectus, lower rectus, external oblique, and internal oblique) of the anterior abdominal wall were collected and analyzed on 20 healthy, male volunteers. EMG activity was recorded during execution of the abdominal crunch, the sit-up, and exercises performed with the Abflex machine… Expand
Relative Activity of Abdominal Muscles During Commonly Prescribed Strengthening Exercises
TLDR
The concept that abdominal strengthening exercises can differentially activate various abdominal muscle groups, but contradict some traditionally held assumptions regarding the effects of pecific exercises, is supported. Expand
An electromyographic investigation of abdominal exercises and the effects of fatigue
TLDR
It was concluded that exercises can be constructed to provide a greater challenge to abdominal muscles, commercially available roller-type equipment appears to be little different from the standard abdominal crunch with bent knees, and fatiguing exercise results in the LRA and URA being more highly activated. Expand
Electromyographic Analysis of Abdominal Muscle Activity Using Portable Abdominal Exercise Devices and a Traditional Crunch
TLDR
The results suggest that portable abdominal devices are most effective if they not only mimic the mechanics of a traditional crunch, but also provide external resistance to increase the involvement of the abdominal musculature. Expand
Electromyographic analysis of traditional and nontraditional abdominal exercises: implications for rehabilitation and training.
TLDR
The Power Wheel, hanging knee-up with straps, and reverse crunch inclined 30 degrees not only were the most effective exercises in activating abdominal musculature but also were themost effective in activating extraneousMusculature. Expand
ELECTROMYOGRAPHICAL ANALYSIS AND COMPARISON OF SELECTED ABDOMINAL TRAINING DEVICES WITH A TRADITIONAL CRUNCH
TLDR
The results support previous findings that portable abdominal devices are most effective if they not only mimic the mechanics of a traditional crunch, but also provide external resistance to increase involvement of the abdominal musculature. Expand
An electromyographic analysis of commercial and common abdominal exercises: implications for rehabilitation and training.
TLDR
The Ab Slide and Torso Track were the most effective exercises in activating abdominal and upper extremity muscles while minimizing low back and rectus femoris activity. Expand
Electromyographic Comparison of the Upper and Lower Rectus Abdominis During Abdominal Exercises
TLDR
Both the URA and the LRA recorded significantly higher mean amplitudes during the Sissel ball curl up than during all other exercises, which had significantly higher normalized EMG activity in both muscle sites than the reverse curl up, the leg lowering exercise, and the SISsel ball roll out. Expand
A comparative analysis of the electrical activity of the abdominal muscles during traditional and Pilates-based exercises under two conditions
TLDR
The electrical activity of the rectus abdominis and external oblique muscles during a traditional abdominal exercise program and an exercise program based on the Pilates method using a ball and an elastic band were analyzed and compared. Expand
ELECTROMYOGRAPHIC COMPARISON OF THE AB‐SLIDE AND CRUNCH EXERCISES
TLDR
The Ab-Slide is a credible abdominal exercise variation, but the crunch should remain the standard abdominal exercise. Expand
Comparison Of Abdominal Muscle Activity Elicited Using The Lean Abs Abdominal Exercise Machine With Popular Abdominal Training Devices And Abdominal Crunch Variations: An Electromyographic Study
TLDR
While all devices elicited abdominal muscle activity when used with proper technique, the “non-crunch emulating” Lean Abs machine dramatically outperformed all other machines and techniques in eliciting high levels of rectus abdominis muscular activity along the full length of the muscle from lower to upper.

Electromyographic analysis of four techniques for isometric trunk muscle exercises.
TLDR
For isometric trunk muscle exercises, a maximum flexed neck with pelvic stabilization through muscle contraction seems to be the most optimal posture for decreasing the lumbar lordosis and for activating trunk flexors and extensors most effectively. Expand

TLDR
It is recommended that a musculoskeletal assessment should be performed before prescribing abdominal exercises, and factors which are important for their safe prescription and effective use are highlighted. Expand
Sit-up exercises: an electromyographic study.
TLDR
The evidence is that the shoulder lift hook-lying (knees flexed) sit-up is the most effective in terms of abdominal muscle activity and the safest in Terms of causing lumbar spinal flexion. Expand
Electromyographic activity of back musculature during Williams' flexion exercises.
TLDR
The results support the following conclusions: pelvic tilt, curl up, knees to chest, and hamstring stretch performed with posterior tilt minimize the electromyographic activity in the lumbar and sacral regions that occurs in conjunction with lengthening of these muscles during posterior pelvic tilt. Expand
The contribution of the rectus abdominis and rectus femoris in twelve selected abdominal exercises. An electromyographic study.
TLDR
The results suggested that sit-ups executed with supported feet required higher MAP of the rectus femoris than sit-up with unsupported feet, no matter whether hips and knees were extended or flexed. Expand
Recruitment of internal oblique and transversus abdominis muscles during the eccentric phase of the curl-up exercise.
TLDR
The results reveal that multisensory cuing with the feet unsupported during the curl-back is an effective method of increasing combined recruitment of internal oblique and transversus abdominis muscles. Expand

The external oblique, rectus abdominis, and rectus femoris muscles of 17 college women were studied electromyographically in 8 sit-up variations to determine the best variation for maximizingExpand
Electromyographic study of duration of muscle activity in sit-up variations.
TLDR
Supporting the feet in both hook and long-lying fast variations was more effective for increasing activity duration of all muscles than the slow supported variations, and speed of performance seemed to be as important as support of the feet or leg position in increasing duration of muscle activity.

An evaluation of four different measures of abdominal muscle strength: patient, order and instrument variation.
TLDR
The manometers to knee and manometer to sternum methods were equally sensitive and more sensitive than the graduated sit-up and blow into manometer methods and was best as it was not painful and exercised the abdominals well. Expand
