The Tortoise and the Hare: Speed of Movement

Speed of movement through an exercise is very important. It is easy to rush through a workout and not focus on key points of an exercise, but you won’t be getting out as much as you should for the time and effort you put in. Different types of exercises and training styles will have different goals, and different requirements for each movement. For the purpose of this topic, we are talking about general movements and not a power/speed development movement.
With most movements, there is a starting position, a midway point, and a return to the starting position. For example, with a squat you start in an upright position, squat down to hopefully somewhere near having a parallel femur, and return to the upright position. It is very common to see people drop to the bottom of the squat, abruptly stop and struggle to return to their upright position. I’m going to urge my quick squatters to slow it down, and here is why:
  1. Speed of movement is often a compensation for stability. People may have a difficult time finding muscular stability, so the speed of movement is increased to compensate. What on earth is being used for stability you ask? Passive restraints such as ligaments and joint capsules as well as faulty bony alignments. You don’t have to be a doctor to know that doesn’t sound good. This leads to a misconception that you are training the muscle properly and a BIG increase in the risk for injury. THAT IS A BIG PROBLEM!
  2. As if that wasn’t enough, you are missing out on the best part of the exercise. Someone may argue that regardless of the manner in which you descend, you are using muscle to stand back up. Although there are great benefits to that portion of the exercise, controlling the decent can be very beneficial. Controlling the downward portion of this exercise is an eccentric movement, and requires eccentric contractions at major muscles groups. Eccentric movements are a major part of how we properly move as humans, but also have been proven to have greater strength gains and demonstrate greater power outputs than their concentric counterparts. SUMMARY: YOU ARE SKIPPING THE MOST BENEFICIAL PART OF THE EXERCISE. Hey, its okay I go to the movies just to watch the previews, too.
This concept applies to many different movements. Not worrying about the speed of movement can lead to increased risk of injury and a lapse in receiving a true training effect. Slow your roll, take control of your movements, and reap the true benefits that you are working for.
