Deep Water Running

As any runner knows, being injured is extremely frustrating! If you are looking to keep your fitness up in a time of recovery, try deep water running (DWR). DWR can be used as a way to maintain your aerobic fitness or to supplement a regular training routine. Aerobic fitness can actually be maintained for about six weeks when DWR replaces outdoor or treadmill running. Here are some things you need to know to get started:

1. Obtain a flotation belt so that you are more buoyant. While you will work harder without the belt, you will not be mimicking a natural running style. By using a more natural running stride, you will be activating the muscle groups that are used in running; therefore, maintaining your ability to run at the same level at which you were previously. This is called the principal of specificity.

2. DWR should be done in water deep enough that your feet do not touch the ground during your exercise.

3. Lean slightly forward from the vertical position with your entire body, bring your knee up to about 75 degrees, and then extend your leg toward the bottom of the pool.

4. Maintain relaxed arms in the same position that you would have them during regular running.

The type of DWR described above is called "cross country" (CC), which most closely mimics a regular running stride by activating the muscles slightly more than when treadmill running. Another commonly used style of DWR is called "high knee" (HK). While HK-DWR will give you a nice workout, it will not activate the appropriate muscles for running at the same intensity as CC-DWR.

Don't Forget To Give Back To Yourself

When you are thinking about which charity to donate your time to this holiday season, consider adding yourself to the list. I agree that giving your time to help others is noble and important, which is why you MUST take care of yourself. You've heard something like this before, but have you taken it seriously? If you don't take care of yourself, you will likely have much less time to give to others. Not only may your life be cut short, but as you get older and continue to eat more and move less, you'll have much less energy for the items that are currently at the top of your priority list. So what is at the top of your list? Do you volunteer at your church, work hard taking care of your children, love visiting your grandchildren, work endless hours taking care of patients in a healthcare facility, volunteer with your favorite charity, etc? If exercise and eating healthy isn't right up there with those items, then you may find yourself falling short on what is most important to you in the near future. So give back to yourself so you can give back to others. This holiday season add exercise to your daily schedule. Do not wait for New Years because New Year's resolutions rarely ever last. When you want to make a change, you just do it. Real change happens any time of the year! Make a commitment to be there for your children, grandchildren, spouse, friends, and anyone else who counts on you. Make that commitment by taking care of yourself!
