Static exercises Warming up with static movements has pluses and minuses. Static stretching can improve flexibility at a given range of motion. It can also improve balance — a bonus for yogis and gymnasts. However, static stretching can create a temporary strength deficit, diminish jump performance and decrease running economy for up to 1 hour, since the sensitivity of tension receptors in muscle is decreased. On the other hand, physiotherapists and strength coaches can actually use this strength inhibition to their advantage, by stretching areas that commonly tighten up and contribute too much to a movement (for example, stretching the front of the hips before running to weaken the involvement of the hip flexors, which tend to be over-strong and tight).
