Arm training Neuromuscular Mechanical Stimulation
Although it is not a new invention, vibration training is a prety new training and rehabilitation methodology compared to traditional methods.
Prof. Carmelo Bosco was one of the pioneers studying the effects of whole body vibration in enhancing sports perfomance and he did a great job.
One of his studies was was to evaluate the influence of vibration on the mechanical properties of arm flexors. He used a group of 12 international level boxers, all members of the Italian national team, who voluntarily participated in the experiment: all were engaged in regular boxing training.
At the beginning of the study they were tested whilst performing forearm flexion with an extra load equal to 5% of the subjects' body mass. Following this, one arm was given the experimental treatment (E; mechanical vibration) and the other was the control (no treatment). The E treatment consisted of five repetitions lasting 1-min each of mechanical vibration applied during arm flexion in isometric conditions with 1 min rest between them. Further tests were performed 5 min immediately after the treatment on both limbs.
The results showed statistically significant enhancement of the average power in the arm treated with vibrations. The root mean square electromyogram (EMGrms) had not changed following the treatment but, when divided by mechanical power, (P) as an index of neural efficiency, it showed statistically significant increases. It was concluded that mechanical vibrations enhanced muscle P and decreased the related EMG/P relationship in elite athletes. Moreover, the analysis of EMGrms recorded before the treatment and during the treatment itself showed an enormous increase in neural activity during vibration up to more than twice the baseline values. This indicate that this type of treatment is able to stimulate the neuromuscular system more than other treatments used to improve neuromuscular properties.
And just to understand the benefits in practical meanings:
During VT the elbow fexors were stimulated for a total of 300 s. This duration was similar to that required to fex the elbow 600 times with a load equal to 5% of the subject's mb. Such a number of repetitions if made three times a week with 50 repetitions each time would take 1 month.
Bellow you can find the complete study.

Honestly, that's what I call a cool story bro. Such a riveting tale, I honestly copy and pasted it to word, saved on my hard drive, backed it up on a jump drive, drove to the bank, put the jump drive in the safe deposit box, and will leave it there until my kids turn about 12 (when they can actually state their age, and ask what it is I'm showing them), when I will pick it up, put it in an old USB drive reader and relay this cool story to them and tell them, "kids, this is what a cool story should look and sound like...not like the stories your generation tells.
