Pedalling And Cadence
Triathlon Training - Bike No Comments »
The two components of pedalling are technique and cadence. Despite the expression ‘it’s like riding a bike’, correct pedalling technique and cadence often do not come naturally and require long practice to cultivate. The three characteristics of good pedalling technique are immobility above the hips (except when out of the saddle), no lateral movement of the legs or feet and a relatively even application of force throughout the pedal stroke. The three most common errors in pedalling technique are body rocking, wide knees and pedal stomping.
Rocking in the saddle is a waste of energy. It’s most common causes are having the saddle positioned too high or riding in too high a gear. However, other causes could be lack of sufficient flexibility in the hamstrings and hip flexors, s well as weak gluteal muscles. If you find that you tend to rock in the saddle, first of all check your seat height and your pedalling cadence.
Failure to maintain a pedalling cadence of at least 70 rpm on all terrain, except steep climbs and descents, is an indication that your gear selection is poor. However, if you can eliminate these causes you should concentrate on correcting muscular imbalances in your lower body with some functional strength training and thorough stretching. You can also complement these measures by paying attention to your form when you ride and consciously not rocking in the saddle.
The problem of wide knees is typically also caused by the above muscular imbalances and is often exacerbated by setting the saddle height too low, which many cyclists do because of their tight hamstrings. To correct wide knees check the set-up of your bike, if it seems right or you cannot comfortably pedal in the correct position then begin work improving the flexibility of your hamstrings. As your flexibility improves you should find that you can adjust your bike set-up. Like before, also pay attention to your form and force those knees in when you catch them creeping wide.
Pedal stomping (also called mashing) is a descriptive term for failing to apply force evenly throughout the pedal stroke. In particular it entails concentrating force on the downward gravity assisted portion of the pedal stroke and allowing momentum to carry the pedal back around to the top. Beyond the gravity factor, the reason this problem is so common is that the muscles that serve as the prime movers for the upward portion of the pedal stroke (gluteals and hamstrings) are relatively weak and under-developed in the average person because of all the sitting we do. Continuing to ‘stomp’ will only make the muscular imbalance more pronounced because of the repeated ‘stomping’ taking place.
In order to overcome pedal stomping it may be worth while working on your ‘pedal stroke cycle’, which means analysing which muscles of your lower body should be invoked at certain points throughout the full 360 degrees of the pedal turn. To describe this with only words would make for a hard read, so next time I blog about bike training I’ll get together a drawing to assist with the explanation. As well as this pedal pattern there are also a few good indoor cycling drills that can help develop this feel. Again we’ll discuss these next time.
In the mean time whilst out cycling try to be more aware of your cadence and cycling form. At this stage of training (base) try to keep your rpm relatively high (approx 90rpm), keep the knees tucked in and if you do ‘pedal stomp’, just try to be more aware of the full pedal stroke through out the full pedal turn.
Happy training!!
