You have seen them, the rows and rows of expensive cardio machines upon which so may people rack up countless hours. Most martial artists are more drawn to the kettlebells or dumbbells then they are to these behemoths. Few of the folks perched on theme look very fit anyway.
So why should you consider including them in your fitness program? There are a couple of good reasons actually. First, if used correctly they can provide a good cardio workout while reducing the pounding your joints take. Second, some machines, like ellipticals are designed to reduce the opportunities for you move in ways that can be harmful to your body.
Most martial artists have serious movement impairments at some time in their careers. Usually these stem from poor training programs that result in muscular recruitment patterns that are less than ideal.
I can’t tell you the number of martial artists I have talked to who complain about their knees popping and grinding, yet they never even consider that all of the thigh kicks they receive, all of the sumo squats they do, all of the crazy exaggerated stances they practice might contribute anything at all to their knee problems.
Once a pattern is loaded in, almost anything you do can reinforce that same pattern. If it is causing problems it takes dedicated intervention strategies to correct. Machines, like ellipticals reduce the opportunity to hyper-pronate by forcing your feet to stay on the platforms and move in a pre-established fashion. This can be helpful in reinforcing correct muscle action.
Every couple of months it is a good idea for all athletes to spend some time allowing their bodies to recover from all the abuse it has suffered. This should be a period of lighter activity, in which the joints are not subject to the same amount of pounding as they have received during the previous training cycles. As we age it is more and more important that we allow our bodies adequate recovery time.
Of course there are some true believers out there in the martial arts world who think they get everything they need from their kata, kihon, and kumite. For these folks this a matter of faith, and apparently nothing will disabuse them of this craziness. More rational souls will realize that their karate will benefit substantially from a more targeted approach to addressing fitness concerns that bear on their performance and health. To these people I would like to recommend giving those funny looking machines a try once in a while.
Take a break from jumping around, lifting people, and pounding stuff for a couple of weeks every now and then. During this time these machines can help you get a sufficient cardio workout without inflicting as much pounding on your feet, knees, and back (almost sounds too good to be true to many of us old timers).
I usually impress the hell out of myself when I switch over from running on grass and pavement to running on the treadmill. The treadmill is so cushy, and it always feels like I can run twice as far. Well the truth is that running on a treadmill is easier than running on either pavement or grass. There is much less to adapt to on a treadmill, so all your effort goes into the run.
Keep in mind that you will not be doing yourself much good at all if you use your arms to hold yourself up while using ellipticals, stairclimbers or treadmills. Hypertonic lats, shoulder problems (actually these are closely related), and back pain are all ubiquitous in karate. Spending thirty minutes propped up with your elbows locked, your lats tight, pretending that you are actually using the machines the way they were intended is a sure way to make your lower back creakier, and your shoulders tighter.
If you can’t keep up without bracing yourself with your arms, turn the machine down. You will burn more calories, and feel better for it.
Now go ahead and give that treadmill a go.
