Many glaucoma patients ask their doctors, “What else can I do to help preserve my vision?” One answer may be to get off the couch—and get moving.  “Aerobic exercise is known to lower intraocular pressure (IOP), which we know protects retinal ganglion cells,” says Harry A. Quigley, MD, professor and director of glaucoma services at the Wilmer Eye Institute at Johns Hopkins University in Baltimore.  “And short-term studies show it may improve blood flow to the retina and optic nerve as well.”

What’s interesting to note is that in order to achieve a positive neuroprotective effect, you don’t have to exercise rigorously.  IOP can be lowered by exercise that raises the pulse just 20-25% —that could be a brisk walk — for 20 minutes, a minimum of four times a week.  “Exercise is free, so the price is right, and glaucoma patients should be encouraged to begin an aerobic program after getting consent from their internal medicine physician,” advises Dr. Quigley.

And of course, regular exercise brings a host of other benefits, including improving blood pressure, heart function, and making it easier to keep your weight down.  And what of the neuroprotective effects claimed by the manufacturers of some topical glaucoma medications? “There is no evidence that any topical glaucoma medicines can save nerve cells in humans,” says Dr. Quigley, after a review of the available literature on this topic. “Both patients and doctors need to be alert to false claims.”

There are 1,440 minutes in every day.  Schedule 30 of them for physical activity such as walking, trikking or using an exercise bike or eliptical trainer!

Regular exercise is a critical part of staying healthy. People who are active live longer and feel better. Exercise can help you maintain a healthy weight. It can delay or prevent diabetes, some cancers and heart problems.

Most adults need at least 30 minutes of moderate physical activity at least five days per week. Examples include walking briskly, mowing the lawn, dancing, swimming for recreation or bicycling. Stretching and weight training can also strengthen your body and improve your fitness level.

The key is to find the right exercise for you. If it is fun, you are more likely to stay motivated. You may want to walk with a friend, join a class or plan a group bike ride. If you’ve been inactive for awhile, use a sensible approach and start out slowly.

There are many tools for providing overload training for sprinting to improve acceleration and maximum speed performance. One of these is to use a weighted sled which is attached to the torso via a rope and harness.

However in developing training strategies, the coach has a number of factors which need to be considered.  Sprinting has be defined as as an initial acceleration phase (0 to 10 m), a phase of maximum running speed (36 to 100 m) and a transition phase in between. Here are some points for you to consider when developing your training strategies for each of your clients.

Muscle fibres – what impact you get from muscle fibre adaptations (ref Sports Med, 1997 Sep;24(3):147-56) .

Neural responses – do muscle recruitment and firing pattern (Sports Med 2001;31(6):409-25) need to be considered?

Kinematics – will there be impacts on technique or biomechanics (ref Australian Conference of Science and Medicine in Sport 2002).

See Peter Maulder’s paper for a detailed discussion about the impact of sled training on the acceleration phase of sprinting.
