I evaluate the effectiveness of this equipment is to strengthen the muscles of the abdomen, nothing more. We will ...
A Swiss ball forces the contraction of the abdominal muscles, as they have to keep the body in a stable position. The instability provided by the bale itself requiring contraction.
However, the contractions can be obtained which are far from high .
"Efficacy of resistance gym ball exercises performed on unstable equipment Willardson , Jeffrey M. MS " A study entitled stated that :
"The performance of resistance gym ball exercises on unstable equipment has grown in popularity , despite a lack of research support for their effectiveness . Resistance exercise performed on unstable equipment may not be effective in the development of type balance, proprioception and stability necessary for the implementation of successful sports base. dumbbell gym ball exercises while standing on a stable surface and have proven most effective in improving the skills of the sport. "
If the " dumbbell gym ball exercises while standing on a stable and have proven most effective in improving skills related to sport surface", then a stable base is definitely the best in training for growth.
Examples of basic gym ball exercises for abs crunches are constant decline and hanging leg raises . Additionally, you can use more weight / resistance to these gym ball exercises and generate more overhead which means more growth stimulation . Want proof ?
The study entitled " The maintenance activity Emg instability and loss of work output
ANDERSON, KENNETH G. , BEHM , DAVID G. " He concluded that :
" The output decline suggests that overhead required for strength training requires the inclusion of resistance training on stable surfaces. "
In fact, there is a loss of force production instability to 59.6 % in stable condition! That's a lot .
Do not waste your effort in the gym in the lower years. Use exercises that provide a stable base and turn the real growth.
