CYCLING AND PEDORTHICS As our population grows older, bicycle riding is an excellent option for people looking for an easy way to maintain cardiovascular and joint health. Many sports are great for you, but are not easily attainable. Come on, everybody knows how to ride a bike. High quality, fun exercise is waiting for you right in your garage. As the blending of recreation and health meet, there can be a seamless union where fun meets attainable exer- cise. necessary with this type of rider- comfort easily out- Modern bicycles have come a long way since that old red Schwinn you and your brother delivered newspa- pers on as a kid. Space age materials like carbon fiber, super light alloys, puncture resistant tires and comfort- able frame designs have brought the newest technology to the masses while steel and heavy chrome are rel- egated to memory. Back to the down stroke, these rotations occur thou- Every cyclist need to think about stance. How aggres- sively a rider is over the handlebars is key. A dead give- away is, how vertical is the seat tube? If it's vertical it's going to be a very harsh and performance stance—far too uncomfortable for a casual rider. Generally, the more vertical the seat tube is the more responsive and powerful the pedal stroke. A “crank forward” stance involves the pedals being forward of the saddle posi- tion creating a more casual riding position. The need for advanced fitting situations and stance control is not weighs performance. The rotations of the cyclist's foot is like a clock. From 1:00 to 5:00 is referred to the down stroke. Even the most casual bicycle rider recognizes this phase. This is where all the power comes from. 5:00 to 7:00 is known as the pull back stage. This is where plantar flexors give way to dorsiflexion and the tibialis anterior takes over. sands of times in an afternoon ride. Cadence refers to the number of revolutions per min- ute. Most recreational cyclists will have a cadence around 60-80 pedal rotations per minute. Racers and performance minded cyclists have a faster and more powerful pedal stroke and cadence, around 90 rotations per minute. In the cycling world, there are spinners—riders who put less force on the pedals and use a higher cadence. Pushers will typically have more force on the pedals with a lower cadence. Higher pedal pressure coupled with lower cadence speeds can lead to knee pain and meniscus damage.
