Accidents happen all the time, but what do you do if you get injured and think you can’t participate? research shows that you should participate anyway. You do everything you normally do, just not with the affected limb. There are other circumstances that might keep them out of activity, but if it is a leg, ankle, arm or wrist, you keep participating. Cross Transfer is the reason why. In simple terms, performing a strength exercise on the unaffected limb will transfer affects to the affected limb.
The TRX Suspension System is an excellent option and you can do it just about anywhere and modify exercises as needed. Below is one study from years ago that supports cross transfer.
Yasuda Y, Miyamura M.
Blood flow in the right and left forearms was determined by venous occlusion plethysmography in ten healthy male subjects before and after training with a hand ergometer. The subjects in group A and B were trained using work loads of 1/3 and 1/2, respectively, of maximum grip strength 6 days/week for 6 weeks. It was found that the blood flow in the left (untrained or contralateral) forearm during exhaustive training of the right hand increased gradually with increasing training periods, and that after 6 weeks of training, grip strength, endurance and peak blood flow of the forearm increased significantly not only in the trained forearm, but also in the untrained forearm. From these results, it is suggested that the increase of blood flow in the contralateral limb after training may, at least in part, be related to the cross transfer effect of muscular endurance.
