Eating less than recommended, yes or no?
Is there a training benefit to eating less than required when doing training rides to purposely put yourself in the box or should you always follow the 1g carbohydrate per kg both training and racing?
Pamela Hinton says:
Eating less than required when training is not beneficial.
Some have proposed that training while fasted (i.e., first thing in the morning) or without adequate carbohydrate consumption will “train the body to use fat.”
However, this strategy is ineffective from the perspective of getting the most out of your training, and here’s why. It is true that not eating before a ride or under-eating (carbs) during the ride will increase the use of fat for energy during exercise. This happens because you either start your ride with depleted glycogen stores or deplete them during the ride. Because your body has no alternative, it has to use stored body fat for energy. So far, that sounds like a good thing, right? But, there’s a high price to pay: if fat is the only fuel available, you are forced to exercise at low intensity.
Carbohydrate mandatory for high-intensity exercise because more ATP is produced per liter of oxygen consumed from carbohydrate than fat.
Training per se causes metabolic adaptations that increase oxidation of fat for energy during exercise: 1) increased release of fatty acids from fat stores during exercise; 2) increased fat storage near skeletal muscle mitochondria for more rapid use; and 3) increased capacity of skeletal muscle to oxidize fat.
The bottom line is that your body will respond best to training if you give it the required fuel.
Cycling with a fused knee
I am a 21 year old female and my right leg is fused at the knee, which makes it so that I am unable to bend it. I am curious if there are any kinds of bikes that I could look into as I cannot ride a regular one. I am interested in just riding the bike around town. I really miss being able to ride a bike and have been looking for a while but just can't seem to find anything that I could ride. Do you have any information on this?
Scott Saifer says:
With a knee that won't bend, you aren't going to be doing any bicycling that seems or looks "normal", so the next question is how close to normal you can get and how far from normal you are willing to go to ride. One off-the-shelf possibility to get you out on the road again certainly is some sort of hand-cycle. A Google search will bring you lots of options there.
I'd love to say that you could ride standing with one leg straight, but that simply won't work. If you really want to be on a bike rather than a trike, a second possibility is pedaling with one leg, rigging a way to get your second leg supported out of the way and probably adding a weight to the right pedal to make it easier to get the pedals around. A recumbent bike would make getting the right leg out of the way much easier than an upright bike.
People with no knee or lower leg at all can ride relatively normal bikes with prostheses. I'm not an expert on such things, but I imagine you might be able to involve your right leg with a prosthesis hinged near your knee in a way that allows you to pedal with both legs.
Good luck. I hope you are able to get rolling again. Do let us know what you decide to try and how it works and of course write again if we can help in any way.
I have two questions regarding interval training.
1. When looking to improve overall performance are there any advantages/disadvantages to doing interval training on hills when the variables are the same as the flat: i.e length, cadence and effort?
2. Should intervals be done on consecutive days or is it best for recovery and performance gains to have a rest or recovery ride day in between? (due to training restrictions I often end up doing intervals back to back, typically one day doing 30X30 intervals (12-16 reps) and the other doing 3X3 (6-9 reps).
Scott Saifer says:
Two good questions!
Many people find it easier to raise heart rate and deliver higher power on hills than on flat, so I suggest that you do intervals on both hills and flat. Being able to make power on the flat roads will turn out to be a very valuable racing skill for TT riding, chasing or breaking away, so doing your intervals only on hills where it is easier is an error.
Do your intervals on non-consecutive days as much as possible to maximize the fitness gains.
Strange Iliotibial Band Syndrome Symptoms
Ever since I discovered this wonderful website, I have eagerly awaited the "Fitness Q&A" articles because many of the tips you give others apply to myself as well. I am a 17 year old competitive cyclist, and though I do not consider myself among the elite, I do tend to place well in almost all the road races I enter. As of now I have been seriously training for a little under two years. Over the summer I ride 200 to 250 miles a week, and during the winter I use the bike trainer for about an hour a day for five days out of the week.
Last winter I encountered some pain in my left knee and decided to go to a physical therapist, he diagnosed my problem as Iliotibial Band Friction Syndrome (ITBFS), and gave me great advice and a stretching routine. Shortly after doing the prescribed stretches, my knee pain disappeared, but one symptom of ITBFS remained, I could still feel my iliotibial band flick over the bone protrusion on my femur. I continue to do this stretching routine three or four times a day, everyday. Over the next summer I returned to my training regimen, and made some wonderful progress, and I was free of knee pain, but the flicking continued.
After it started getting cold, I decided to take a month off with hopes of getting rid of the 'flicking' sensation in my knee, and I discovered something strange. My left knee became sore, not excessively so, but there was a small amount of pain when I would stand up from a crouched position or something of that sort. After riding again, I noticed this soreness disappeared, and then came back again after not riding for a few days. Once I resumed winter training, I found the flicking was still present, and the soreness in my knee was completely absent.
I debated returning to the physical therapist. but resolved to email the the panel of experts because my physical therapist was not as well versed in cycling specific injuries as he is injuries specific to more popular sports in my area. Any advice regarding this issue would be greatly appreciated.
Thanks for your time,
Steve Hogg says:
The 'flicking' sensation is caused by a muscle, tendon or ligament moving across a bony protrusion or landmark. It might be because you have some minor anatomical abnormality but given what you have said about your ITB history on the left side, it is more likely that you’re on seat symmetry when riding is not what it could be. ITB niggles that arise on a bike are almost always a product of dropping the hip on the other side and subsequently challenging the plane of movement of the hip on the affected side.
The solution could be as simple as dropping your seat a few mm. If the seat is too high, next to no one sits squarely on the seat and overextends each leg equally. What normally happens is that they will drop one hip, mostly but not always the right hip, and overextend the other leg through a less than ideal plane of movement.
Of course there are other possible reasons as well but seat height is by far the most common. I would suggest dropping your seat 5mm as a test and leaving it like that for 2 weeks of consistent riding. Then get back to me and let me know what happened.
Low volume training and ‘Wattage’ drift
Good day All,
With increasing non-cycling related responsibilities I have fairly recently adopted a high intensity low volume type of training plan. My question relates to my rest days. If I take the day off completely I feel horrible and find it difficult to get up for the next training ride. If I ride at an active recovery pace (around 40-50% of threshold power) I feel better and the next day's workout is significantly easier to get up for. The question is am I hurting myself by riding on my off days?
The second question relates to the power readings on my power meter. I use a powertap and calibrate it before every ride. I am familiar with cardiac drift but is there such an animal as power drift? I find the wattage required to maintain a given speed continues to rise for about 40 minutes when it will eventually flatten out for the speed I am riding. This is seen on an indoor trainer so wind and hills are a non-issue.
I look forward to your answers.
Scott Saifer says:
Fun questions, thanks! No, you are not hurting yourself by riding on your rest days, so long as the rides are very, very easy. 40-50% of threshold power certainly counts as very, very easy. Moving blood through the tissues, stretching them, keeping the muscle fibers sliding over each other... all these are good for recovery. So long as you are not generating new fatigue, activity is good on rest days.
Yes, there is such a thing as power drift on certain trainers. For instance, I have several fluid trainers. In one of them the fluid seems to get less viscous as it warms up so that the power required to maintain a speed is quite high at first but decreases with time. This is the opposite of the effect you are noting. I'd guess that some part of your trainer is increasing friction as it gets warmer. To test, I'd suggest a roll-down test done in the first minutes of a ride and repeated 40 minutes in. If the roll-down time decreases, you know that friction has increased. Then you can attempt to determine why.
