Maximize Your Cardio Program Part 4: Speed and Efficiency

The fourth and final article of this series on aerobic conditioning concerns increasing how fast you move. This article is for high achievers. If you are concerned only with decreasing your risk of chronic diseases, apply the suggestions from Part 1 and 2. Add Part 3 and 4 if you are fit for high intensity training and want extra challenge. Fortunately, training to increase speed is "fast" relative to your fitness level but not necessarily "hard" like the training for aerobic capacity discussed in Part 3.
Plyometric drills, or stretch-shorting cycle training, are another training method used to increase speed and efficiency. Children's games such as jump roping, hop scotch, and leap frog are great examples of plyometric training. Drills and games that involve jumping and leaping high or far against little or no resistance teach the body to explode quickly and move efficiently through space. Although we usually associate these drills with team sports such as football and soccer, endurance athletes, dancers and anyone who wants to learn to move quickly and lightly on their feet benefit from plyometric exercises. For example, one study showed that recreational 10K runners increased their power output in their legs through single leg jump work. These runners out-paced their non-plyometric trained competitors. The concept is simple: teach your body to do something difficult, like hop high and far on one leg forward and backward, so that running or cycling will feel less difficult.
Third, strength training may help improve speed and efficiency. Strong muscles, tendons and joints help carry your body faster over greater distances. Furthermore, strength training teaches the body to move against resistance without high joint impact movements like plyometric drills. Many endurance athletes perform no lower body strength training or limit resistance to about 15RM (1RM = your 1 repetition maximum). Some believe that since strength training works anaerobic systems more than aerobic systems, there is no benefit for endurance athletes. However, recent studies show that strength training improves speed and efficiency in endurance athletes. My personal experience taught me that this is true. I ran faster with less effort when I performed high intensity lower body strength training once a week.
"High intensity" does not mean over-training. It refers to intensity of about 8 to 12RM per set. This intensity recruits enough fast and slow twitch muscle fibers to increase muscle, tendon, and ligament tensile strength. Women tend to work at intensities too low to produce results while men tend to work at intensities too high for their level and compromise form during exercises. First, build a base level of local muscular endurance by working in the 15RM or higher range, but then increase intensity to 8 to12RM per set for about 3 to 4 week and see how you feel. If you are happy with your results, continue to follow a periodized program varying volume and intensity over several weeks. If you feel like you are overtraining, cut back your volume and intensity until you feel prepared for greater strength work.
In summary:
1. For repetition work, work at a "fast" pace greater than 100% of your VO 2 max for short periods (up to 2 minutes) and follow with full active recovery periods of about 5 to 6 minutes. Concentrate on form, moving efficiently, and staying relaxed at a faster pace.
2. Limit repetition work to 1 session a week for about 5% of the total cardiovascular training volume for the week.
3. If outdoors, perform repetitions on flat, dry terrain on a clear day. Repetition training is great on treadmills and in spin classes since many machines allow you to program your workout and keep your speed and time consistent.
4. Other training options to increase speed include plyometric training and strength training. Plyometric training involves fun drills you probably enjoyed as a child like single leg hopping and frog leaps. Only about 15 minutes of plyometric training a week can improve speed and economy, add variety to training, and keep training fun. Strength training is a great option for people who want to increase muscular strength and power but limit high joint impact movements. First build a base of local muscular endurance and then progress to higher intensity maximum strength work.

Top-level comments on this article: (4 total)Thanks for the fitness tips! I'll have to work my way up to this regimen, though.Yamileth, thank you for reading and responding. Stay consistent with your program, and you will be a pro before you know it :)
I get a full workout,feel both exhausted and exhilarated and all from just reading your articles! After my nap,I shall read more of your stuff:Thanks! Paul SchroederThanks, Paul. I enjoy your sense of humor.
Paul said it better than I could. :-)Thanks for sharing your wisdom. I am looking for motivation.Thanks Crystal. Helpful hint: to get motivated to exercise, just move. Just move for a few minutes. It's like writing. The inspiration comes when you stop thinking and start typing on the computer :)
Hi Deana. Great article. Thanks for sharing your knowledge. All I can manage at this time is jumping rope and running up and down the stairs. To good health! ~Nenita~Hey Nenita - jumping rope and running stairs are great exercises. If you eat well, a few minutes a day of heart pumping exercise might be all you need to at least prevent chronic disease. Seriously, a little goes a long way.Thank you Deana for the encouragement, much appreciated.
