The wise man once said, “There is a time for every purpose and for every work”. Implied in this saying is there is also a wrong time. The value of an event is often established by “when” it happens.
The same is also true of the timing of muscles in movement. Researchers have found that the timing at which muscles fire is very important. Studies have shown that people with back pain engaged the muscles that stabilized their trunk muscles, after the muscles that move their shoulders or thighs, while people with healthy backs engaged the stabilizing trunk muscles before their muscles in the shoulders and hips. What is probably even less obvious is that having the proper timing in one movement pattern is associated with a seemingly unrelated movement. In my experience, I have seen a correction in the ability to roll on the floor take away knee pain in a squat. Titleist Performance Institute has screened thousands of golfers at all levels and found that golfers who are unable to perform an overhead deep squat will have trouble with early extension during their golf swing.
This illustrates why movement screening is important in helping to design training program. Picking the right exercise(s) and performing them correctly can help improve many other movements. On the other hand, “putting fitness on dysfunctional movement patterns”, will often lead to frustration, injury, and pain.
