Cycling Training Tips

Jesper Bondo Medhus

I am a medical doctor with a special interest in cycling training. I work at the Hospital of Vejle using clinical physiology and nuclear medicine to diagnose cancer and heart patients. I have written two e-books: Time Effective Cycling Training and 12-Week Winter Training Program.

Report about time trial aerodynamics

Your body position and the bike’s aerodynamics play a big role in time trials. A couple a years ago I read a comparing of different body positions and what influence it had on the finishing time in a 40k time trial. I am not sure, but I think I saw these results back in 1997, so this is not breaking news, rather nostalgic news.

Aerodynamics is important in time trials

An interesting question is how much time you can save by using expensive aero wheels, an aero frame or saving some pounds? There are probably more precise answers to these questions than this report calculates for you, but it gives you an idea of what difference these changes can give you.

One of the interesting findings is that slower riders will benefit more from a lighter bike than top riders will, while aero wheels and frames will give the biggest advantage to faster riders. This is probably because the aerodynamic drag requires a relative larger percentile of the workload at high speeds.

Optimized aerodynamics is better than weight savings
The conclusion for this report is that the biggest changes in aerodynamic drag and in cycling performance come from changes in body position. A more aerodynamic body position can improve your 40k time trial by over 6 minutes (that is really something!) The report also concludes that improving the bike’s aerodynamics is more important than weight savings. A pair of aero wheels can reduce you 40k time trial time with 1 or 2 minutes.

Carbon Cycling Shoes have more Stiffness

Carbon cycling shoes are stiffer than regular ones.

Carbon cycling shoes look better than traditional cycling shoes made of plastic. But the question is, do they perform better or are they only more expensive? Well, I found a scientific study that tested the stiffness, which is a very important detail when I decide which cycling shoes to wear. Comfort and weight are also important factors, especially comfort. It is though important to remember that shoes with the best comfort often lack stiffness. It is very difficult, if not impossible, to achieve a high degree of stiffness and comfort at the same time.

Carbon cycling shoes are stiffer
In the study shoe stiffness measurements were collected under controlled conditions in the laboratory with a dynamic hydraulic tensile testing machine. Measurements of plantar pressure were done using a special sensor in the soles while subjects pedalled at a controlled power output. The results from these tests showed that the carbon cycling shoes produced a significant, 18% higher peak plantar pressure than plastic cycling shoes. So carbon cycling shoes are stiffer and that is also what riders tell me when they have switched to this more expensive foot wear.

12 week strength program for cyclists

Here is a very effective strength training program for cyclists. The program is based on multi joint exercises with free weights, which indicate that this program is not for beginners. If you are not familiar with lifting free weights, consider training the same exercises in a machine. Ask a fitness instructor in your training gym.

When using this strength program:

Ӣ Warm up before lifting
Ӣ Never train to failure
Ӣ Use as heavy weights as possible (still no failure training)
Ӣ Be explosive in the concentric phase
Ӣ Rest periods of at least 2 minutes between sets

How to Achieve Better Results with Spinning

1. Warm up before spinning lesson
Spinning lessons have a normal length of around 50 minutes. For trained cyclists this is a very short amount of time, when this time includes both warm up, intervals and cool down. Remember that most spinning lessons are made for people that are not very familiar with cycling training. Therefore I suggest you do a warm up before you enter the spinning room to get more training time.
2. Drink water with electrolytes and carbohydrates
Spinning rooms have a very high temperature and high humidity. Therefore it is quite normal to sweat much more than you are used to. Some people believe that they sweat more at spinning lessons because they work harder. That is not true. They sweat more because of the climate, not because they work harder than normal. I will recommend you to drink water with electrolytes and carbohydrates to maintain a high level of performance during the whole session.
3. Choose intervals carefully
Spinning instructors plan their lesson to be interesting and challenging for a wide range of riders. Most of them train spinning only 2 to 3 times week, so they can use all their effort in this short period. If you do not like the program made of the instructor, consider to use your own program or one of the indoor cycling programs here on Training4cyclists.com. It is possible to ride one of these programs without telling the instructor. Just remember to stand up and sit down when the instructor tells you to (and ignore his commands about pacing strategy).
4. Remember rest days
You can not do intervals every single day. Some days should be easy days. If you go for a ride in the spinning class on one of these days, please remember your goal with the training.

Power Crank can improve upstroke pedalling

Power CrankIt is very difficult to train the hamstrings and hip flexors on a regular bike. Basically we use most of our efforts to push the pedals down and never to pull the pedals up. Power Crank offers a different way to train for a better upstroke pedalling power. The pedal arms on the crank work independently of each other, which forces you to work much harder in the upstroke pedalling phase. Now you are forced to make an active upstroke to keep pedalling. That should make you stronger and more efficient. I can not recommend the Power Crank yet, because I have never tried it and neither have the riders I work with. But hopefully I will try it in the future.

Better than one leg riding
I have tried to ride my bike with only one pedal clicked in, but I don’t think that works very well. It does not feel like cycling and it is difficult to maintain a reasonable speed. Therefore I am quite interested in experiences made with the Power Crank system. So if you have tried it, please let me know about it. Otherwise, we will have to wait until I have tried it and made a review of the Power Crank.
