Objective:
To determine whether prehabilitation, or exercise performed before muscle unloading, can effectively mitigate decreases in neuromuscular function typically elicited by unloading.
Design:
Ten healthy, untrained young men (20.9 +/- 1.3 yrs; mean +/- SD) were initially tested for strength, work, power, and electromyography. After completing six prehabilitative resistance training sessions, they repeated testing of neuromuscular function. Immediately after the second neuromuscular function test, participants began 7 days of muscle unloading that was immediately followed by a third testing session for neuromuscular function.
Results:
Prehabilitative conditioning failed to prevent significant (P 0.05). Also similar to that study, the decline in strength noted here was significantly correlated with a decline in electromyography.
Conclusions:
The prehabilitation program used here did not moderate unloading-induced reductions in neuromuscular function. It remains to be determined whether more extensive prehabilitation protocols may be more effective.
