View Full Version : Support for control from additional muscle utilisation

In badminton there is anecdotal support for using forearm rotation in low power movements to improve control (in addition to the usual contributions from elbow and sometimes shoulder, wrist). Can anyone suggest any theoretical/data driven justification for this belief?

I have read that when a person desires control over speed they tend to 'freeze' joints to simplify the movement. This would recommend against using unnecessary movements like forearm rotation. Could justification come from the impulse/control data? Maybe several small muscle contributions are more accurate than fewer larger contributions.

Another reason I could think of is that it mimics the use of forearm rotation in the high power shots where it is quite important and thus is easier in terms of motor learning.

Any ideas?

Thanks
