The importance of warming up
With the temperatures hovering around freezing, it is a good time to discuss the importance of warming up!
After speaking with clients and fellow teammates, I have found that time isn’t always being taken to sufficiently warm up before physical activity. Warming up is an important part of injury prevention and athletic performance.
Warming up increases body temperature, and has the following physiological effects:
- increases the dissociation of oxygen for use by muscles
- reduces the energy required to activate metabolic reactions in the body
- dilates blood vessels and increases blood flow to muscles
- reduces muscle viscosity resulting in smoother contractions
- increases sensitivity of nerve receptors and the speed of nervous impulses
- increases the length of stretch and the force required to tear a muscle
Your warm up can be passive, like a hot shower or sauna, or active, like going for a jog on the treadmill or performing drills and movements specific to your sport. Sport-specific warm ups provide the muscles with the opportunity for movement rehearsal.
Stretching is often included as part of warming up, and may be either static or dynamic. Static stretching involves taking your muscle to the end of its available length and holding it there. Dynamic stretching involves using active muscular contractions and momentum to lengthen your muscles. Examples of dynamic stretches include:
- Walking lunges – forward or diagonal
- Lateral shuffles
- High knee pulls
- Skipping with high knees, using arms to drive forwards or upwards
- Leg swings
Evidence supports including dynamic stretching in your warm up to improve performance. When compared to static stretching, dynamic stretching can improve vertical jump height, sprint time, agility, and other performance measures.
Adding a warm up before your sporting activities is a great way to help prevent injury and can enhance your performance, especially if dynamic exercises are included. Ask your therapist for examples of warm up exercises specific for you and your sport!
