Core Zone - Ab Training

Core Training

Abdominal exercises are useful for building the abdominal muscles. This is useful for improving performance with certain sports, back pain, and for withstanding abdominal impacts (e.g., taking punches). According to a 2011 study, abdominal muscle exercises are known to increase the strength and endurance of the abdominal muscles.

It has been highly disputed whether or not abdominal exercises have any reducing effect on abdominal fat. The aforementioned 2011 study found that abdominal exercise does not reduce abdominal fat; to achieve that, a deficit in energy expenditure and caloric intake must be created—abdominal exercises alone are not enough to reduce abdominal fat and the girth of the abdomen. Early results from a 2006 study found that walking exercise (not abdominal exercise specifically) reduced the size of subcutaneous abdominal fat cells; cell size predicts type 2 diabetes according to a lead author. Moderate exercise reduced cell size by about 18% in 45 obese women over a 20-week period; diet alone did not appear to affect cell size.

Functions of abdominal muscles
Abdominal muscles have many important functions, including in breathing, coughing, and sneezing, and maintaining posture and speech in a number of species.[3] The anterior abdominal wall is made up of four muscles—the rectus abdominis muscle, the internal and external obliques, and the transversus abdominis."The two internal muscles, the internal oblique and the transverse abdominis, respond more to increases in chemical or volume-related drive than the two external muscles, the rectus abdominis and external oblique; the basis for this differential sensitivity is unknown".

Core training
Further information on Core: Core (anatomy)
Not only can a one-sided preference for abdominal muscles (lack of exercise focused on other core muscles) result in creating muscle imbalances, but the effectiveness of exercise is also far from what could be achieved with a balanced workout planning. Core training frequently utilizes balance exercises. These are characterized by an unstable position that requires the use of a wide range of muscles which help balance oscillation of the center of gravity. We can balance both in static positions and while performing dynamic movements.[citation needed]

The goal of core training is definitely not to develop muscle hypertrophy but to improve functional predispositions of physical activity. This particularly involves improving intra- and intermuscular coordination or synchronization of participating muscles.

Involvement of the core means more than just compressing abdominal muscles when in crouching or seated position. The role of the core muscles is to stabilize the spine. Resisting expansion or rotation is as important as the ability to execute movement.

The abdominal muscles can be worked out by practicing disciplines of general body strength such as Pilates, yoga, T'ai chi, and jogging among others.[according to whom?] There are also specific routines to target each of these muscles.

Momentaneous activity
One way to estimate the effectiveness of any abdominal exercise is in measuring the momentaneous[jargon] activity by electromyography (EMG), with the activity generally being compared to that of the traditional crunch. However, an exercise of lower activity performed during a longer time can give at least as much exercise as a high-activity exercise, with the main difference being that a prolonged duration results more in aerobic exercise than strength training.
