Which Muscles Does Riding a Bike Develop?

Cycling is a fantastic sport that is enjoyed all over the world by millions of people each day. Lots of people ride a bike just as a means of transport, whilst others include cycling heavily in their fitness regime. 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. But which muscles get worked the most when cycling.

Quadriceps (thighs). Without doubt the muscles that produce most of the force when cycling are the quadriceps. 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. When travelling at speed the quadriceps contract and relax at an incredible rate and a great deal is demanded of them.

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.When the leg is straightened by the quadricep muscles, there is still a percentage of power that can be gained by flexing the calf muscles and pointing the toes downwards. Pinarello make pedals that dynamically pivot to squeeze every last bit of power juice from the calf muscles.

Hamstrings. After the quads have forced the leg down and helped move the bike forwards, the hamstrings work to to pull it back up again and reset the leg ready for another push. 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

Why Mountain Biking In France Is Popular

One of my favourite past times is to go mountain biking down countryside trails and travel long distances from one town to another. For me this is an enjoyable form of keeping fit and you have the added benefit of appreciating the scenery. Mountain biking does not necessarily have to be enjoyed in your own home territory and one can be involved with mountain biking abroad. Places like France, Italy, Spain, Africa and Australia.
Mountain biking in France is more popular than any other destination because of the smooth and challenging trails that make biking here more fun. The French Alps is famous for holding the popular Tour de France biking event, whereby thousands of spectators come from all over the world and support the contenders. The Alps is also popular with skiing holidays and professional skiing competitions, which has placed the French Alps as one of the top destinations for activity holidays.
The Tour de France has helped to keep the Alps to maintain its reputation for being one of the best experience mountain biking in France as a whole. The first Tour de France event began in 1903 and is structured so it is partaken in stages rather than one long marathon. History will reveal that the Tour de France was largely influenced and inspired by the popular sporting magazine in France, called Le Velo. Like most sporting magazines, this focussed on sporting events but also included politic and current affairs in France.
Le Velo was produced and published to symbolise the innocence of Alfred Dreyfus, who was accused and found guilty of selling secrets to the Germans. There was a large division between the people of France, with one side favouring his innocence and the other believing he was guilty. Some of the advertisers were against what Le Velo stood and were very much against the support of Dreyfus's innocence. Those that withdrew their advertising later published their own rival magazine.
L'Auto was established and to promote it the Tour de France began. This was also a publicity spectacle to rival Le Velo and their event, Paris-Brest et retour organised by editor Pierre Gifford. Originally, the race was discussed to be a five weeklong tour, however with only 15 entrants this was then reduced down to just 19 days. Cycling journalist Geo Lefevre and Editor Henri Desgrange announced the event on January 19th of 1903 - thus born a new trend of mountain biking in France.
The public were caught and drawn in by the event, from the growing number of entrants (who were offered a daily allowance) and the entertainment attractions (some amateur and unemployed entertainers). The tour was split into stages of riding 400km, this saw the riders riding into the night, which captured the spectators attention. After the event, the magazine sales went from 25,000 copies sold to 65,000. By 1933 when the Tour had finished Desgrange had received a record of 854,000.
L'Auto magazine was not a direct predecessor to the now popular magazine L'Equipe, but was a spiritual figure and influence to the current organisers of the Tour. This is not directly organised by L'Equipe but is run by its owners called Societe du Tour de France. To this day this is an event which has grown on a massive scale over the years. This has influenced much of France to see many holidaymakers take part in mountain biking in places like the French Alps, but also open up other events like the Tour such as Giro d'Italia based in Italy and Vuelta a Espana based in Spain.

Anna Stenning loves to go mountain biking in France as this is her favourite form of exercise to stay fit and healthy.

Get In Gear For Your Mountain Bike

Necessary equipment for the casual bike rider consists of a helmet, and a headlight if there's a chance of biking at night, and that's about it. Anything else is gravy.
The same can not be said for the mountain biker. To have a safe and enjoyable ride, the mountain biker needs quite a bit of gear.
Even more so than for the casual biker, a helmet is a must. And take care about choosing a helmet. A poor-fitting helmet is of no use, so make sure it fits your head securely.
A good pair of gloves serve two purposes. You'll get a better grip on the handlebars with your gloves, and of course should you take a spill your hands won't get torn up.
Clothing
What to wear? Most people go mountain biking in the summer, so they wear shorts, t-shirts, and tennis shoes. If they're the hardy sort, they'll put on sweatshirts and pants for the colder months.
But it's also a good idea to wear padding on knees and elbows. The thing about mountain biking is that it's not a question of if you'll fall, but when. So it's only common sense to wear padding and prevent a serious injury. If you're a dedicated rider you don't want to have to spend any time off the bike recuperating from a broken arm when with a little common sense you could avoid the problem.
Shoes
Don't forget the shoes! These days shoes are designed especially for every sport under the sun, and mountain biking is no different. As a mountain biker you want to make sure your feet stay on the pedals, and you want shoes that are comfortable to well as well.
Accessories
A new trend in mountain biking is riding at night. Well, if you're going to ride at night you've got to have a light! If you're going for long distances you'll want to have a hydropack of some kind, so that you can drink liquids on the go.
It's possible to scour the web for your clothes and accessories, but to be sure of a good fit, it's always best to give as much business as possible to your local bike store.
The Bike
You've got the gear, now you need the bike.
And these are not your granddaddy's bikes. Technology has improved the design of bicycles in every way, and quality bikes are offered at affordable prices - but you've still got to pick the right one for you.
The best thing to do when choosing a bike is talk to owners of various types of bikes - maybe even borrow a ride on them, so you can compare the differences in saddle feel, shock absorbers, handling, and most importantly, weight. Don't just talk to one person, get a good cross-section of opinions.
If you're going to be a competitive mountain biker - taking parts in races - you'll need a more expensive kind of bike, of course, one with a titanium frame and all the bells and whistles. If you're just going to be going out to the trails on the weekends in your version of kicking back and relaxing, you won't need that much bang for your buck
There are two main types of mountain bikes: the Hardtail, which has a frame with no rear suspension and the Softtail, which has a frame with a small amount of rear suspension. The most comfortable bike is perhaps one with full or "dual" suspension - a front suspension fork and a rear shock.
The type of bike you get also depends on the kind of riding you'll want to do: cross-country, enduro, free ride, downhill, etc. Again, you'll want to talk to fellow riders to see which is the best kind of bike for the particular kind of riding you want to do.
