Warming your body up for exercise should consist of exactly that: warming up!  Doing a general body warm up of 5-10 minutes in order to get your core temperature up and your blood flowing to the muscles is essential to improving muscle performance. Depending on what activity you are about to engage in, a brisk walk, some jumping jacks, or riding a stationary bike can do the trick.  Tuck jumps, rope skipping, or running on the spot can also adequately warm the body up along with any other cardiovascular activity you might enjoy. Be sure not to let your body cool down once it is warmed up.  You shouldn’t feel like you cool down until after your activity is fully complete.  If for some reason you have a time of inactivity in your exercise where you feel yourself cool down, you should get the core temperature up again with another short bout of a general body warm up activity.
 

There has been a lot of talk about neuromuscular warm-ups over the past few years but what exactly does that mean? A neuromuscular warm up focuses on priming the nerve-muscle connection so that they are both ready to be activated, and are ready to be activated properly during the activity you are about to engage in.  Neuromuscular activities as part of a warm up ‘turn on’ the neuromuscular connections in your body.  It’s a way of getting your “head in the game” by activating the brain’s connection to your joints and muscles. They remind your body of the best way to activate your muscles so they fire in the right order with the right force, you are not under the pressure of performing the actual sport. Neuromuscular activities improve your body’s internal coordination and get the muscles working at just the right time to most effectively support the body.  Along with a general body warm up and dynamic stretching, regularly warming up the nerve-muscle connection can significantly reduce the chances of being injured during your activity. Neuromuscular warm up activities should include balance activities, agility type activities, jumping and landing technique exercises, stability exercises, and strengthening while under load (eccentric strengthening) exercises.  Neuromuscular activities can be done before, after, or in between doing dynamic stretches.  Your physiotherapist at Rutherford Physio & Sports Clinic can teach you the best specific neuromuscular warm up activities for your individual situation.
 

Dynamic stretches use movement in order to prepare the joints and tissues for the repetitive motions of the activity you are about to engage in.

For the upper extremity, examples of dynamic stretches are arm swings across the body, or wide arm circles. Lower extremity stretches might include back and forth or side-to-side leg swings.  It is also encouraged to perform simulated movements of the sport or activity you are about to engage in. For example, a golfer could simulate a swing several times (with or without a club), a runner may jog on the spot, or a swimmer could practice some strokes lying over an exercise ball poolside. Think of the dynamic stretches as ‘mini-rehearsals’ for the main event!

Some points to remember when performing dynamic stretches:

• Warm up your body first, then stretch while your muscles are still warm and do not let your body cool down before engaging in the task at hand.
• Move through your range of movement, keeping control of the movement with your muscles.  Do not allow momentum to control the movement by "flinging" or "throwing" your body parts around.
• You may feel light resistance in your muscles, but you should never feel pain during the stretch.
• Start with slow, low intensity movements, and gradually progress to full-speed movements through range of motion. Complete these motions for several repetitions at once (10-15 times.)

As mentioned above, there is overwhelming evidence to refute the use of static stretches as part of your warm-up activity.  Although once thought to increase the actual length of muscle fibers, improve athletic performance, and reduce the risk of injuries if done prior to activity, the evidence does not support these long-standing claims.  Despite these claims, static stretching continues to be used in many athletes warm-up regime, and they are still prescribed by many sport and health professionals to be done in order to ‘prevent injury’.  So when are static stretches useful and how are they helpful?
 
Static stretches can be useful as part of your cool down or part of a rehabilitation program in order to recover from an injury or improve your flexibility.  If you are dealing with an injury, the stimulus of a static stretch may help encourage scar tissue to be laid down in the proper direction as well as encourage the building of tensile strength in the healing tissues.  In addition a static stretching may assist the recovery of that injury by allowing you to tolerate greater ranges of movement over time.  The same occurs if you are simply trying to improve your flexibility.  Interestingly enough, although it may feel like you are increasing the length of your muscle fibers and tendons when you statically hold a position, the current evidence shows that this is likely not the case. The improvements in range of motion that one sees over time are not actually due to increased muscle fiber length but may simply be due to one’s ability to tolerate the stretch sensation at further end points.

 
Some points to remember when performing static stretches:
 

• If being done post exercise to increase flexibility, be sure to stretch while the muscles are still warm
• Slowly take your muscles to the end of their range.  You will feel slight resistance in the muscle, but you should never feel pain during a stretch.
• Hold the stretch in a static position.  Do not bounce.
• Maintain each stretch for 20-30 seconds.  Repeat each stretch 2-3 times.

Unfortunately static stretching after exercise has not been shown to prevent the post-exercise soreness that one often feels 1-2 days after an intense exercise session.  Warming up as described above may have a small effect on how sore you feel a couple of days later, but the best way to reduce this soreness is just simply to not do too much too quickly! Gradually increase your workout intensity over a time frame and maintain a good intensity so that fluctuations don’t occur, which will cause soreness once again.
 

Stretching is an integral part of keeping the body fit and healthy.  By using the above tips to maximize the effectiveness of your stretching, you can decrease your chances of an injury and if needed, improve your flexibility. 

Don’t forget that if you have any specific stretching needs it is best to consult your
physiotherapist at Rutherford Physio & Sports Clinic so you don’t stretch your limits! Your physiotherapist can advise you on warming up and stretching for you individual situation in order to ensure you are getting the most out of your overall stretching regime.
