The Muscles That Get The Most Work From Bike Riding
Bike riding is one of those sports that anyone can enjoy and the benefits are almost limitless. The motivations for cycling vary, from just wanting to get a bit of fresh air, to wanting to dramatically enhance your fitness. The fitness benefits for your muscles varies quite a lot depending on which type of cycling you do. Cycling for long periods of time, but at reasonably low force, will encourage your muscles to build slow-twitch fibers and improve their endurance levels. On the other hand, if you cycle hard and fast, your muscles will build fast-twitch fibers and become more powerful. So which muscles get worked the hardest when you ride a bike.
Quadriceps (thighs). Without doubt the muscles that produce most of the force when cycling are the quadriceps. These are the muscles that straighten out the leg and produce the down force on the pedals, which in turn rotate the crack. Racing bikes in fact are designed to locate the quads directly over the crack so that maximum efficiency is achieved. When cycling fast, these muscles are contracted and relaxed hundreds of times a minute and so they need to be in good shape.
Gastrocnemius (calf muscles). Although the calf muscles are much smaller than the quadriceps, they still do and important job of transferring power to the pedals. 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 doesnt 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
