Be Slim, Be Fit, Have Health

Cycling is a fantastic sport that is enjoyed all over the world by millions of people each day. Some use cycling as a means of getting from A to B, whilst others cycle to boost their fitness and tone up their muscles. The fitness benefits for your muscles varies quite a lot depending on which type of cycling you do. If you cycle very long distances at relatively low intensity, your muscles will become very good at endurance and will build many slow-twitch fibres. Conversely, if you ride at a high intensity over shorter periods, you will develop more fast twitch (powerful) fibres and build muscle size. So which muscles get worked the hardest when you ride a bike.

Quadriceps (thigh muscles). When cycling, its is the muscles at the front of the legs that provide the majority of the forces and thus are worked hardest. These muscles work to extend the knee joint and provide a downward force on the pedals, which is then passed onto the crank. Racing bikes in fact are designed to locate the quads directly over the crack so that maximum efficiency is achieved. The quad muscles thankfully adapt quite quickly to exercise, which is lucky as bike riding forces them to work at quite a rapid rate.

Gastrocnemius (calf muscles). The muscles of the calf work just as hard as those of the thigh, and relative to their size they produce a lot of power. Flexing the calf muscles when the leg is in a straight position, points the toes towards and adds a small boost to the overall power output. Pinarello make pedals that dynamically pivot to squeeze every last bit of power juice from the calf muscles.

Hamstrings. It may be the thigh muscles that provide most of the forward momentum when riding, but in order to flex the legs and prime them for the next downward push, it is the hamstrings that do the work. This doesn?t require much force on a standard bike as the rotation of the pedals pushes the leg up but when you use cycling shoes that clip to the pedals, a large amount of additional force can be generated by these muscles in the upward movement
