With all of the emphasis on carbohydrates over the years concerning recommended diets for endurance athletes, the answer is probably, YES! Obviously, it is very important to eat plenty of carbs, but not at the expense of adequate protein intake. Protein deficiencies are too common amongst endurance athletes and have a devastating effect on performance and health. Some of the symptoms to look for are slow muscular recovery from workouts and lower than normal strength. However, fatigue, lethargy, anemia, and other more severe conditions can develope as a result of ongoing protein deficiencies.
In this first part of a two part series, I will examine some myths about protein and what levels you should try to maintain in your diet. As you read this article remember that (protein is required for all aspects of repair and buidling muscle tissue.)
Myth #1 - "Only bodybuilders need hi-protein diets". The truth is that the protein requirements of endurance athletes and bodybuilders are very similar. It is only the way in which the body uses the protein that is different. Bodybuilders need protein to actually build more muscle tissue. Endurance athletes on the other hand need protein to repair existing muscle tissue that is undergoing constant breakdown from day to day training.
Myth #2 - "Eating a high protein diet will cause unwanted weight gain and muscle growth". The truth is that the type of training you engage in will determine whether you "bulk" up or not. High volumes of endurance training do not tend to produce muscle bulk, regardless of protein intake- Whereas relatively low volumes of strength training will. Either way, protein is going to be required to service the muscle tissue.
By now you are probably wondering just how much protein is enough for your needs. Well, I believe a good rule to follow is 1/2 gram of protein per pound of body weight per day. This means that if you weigh 150 pounds, it is going to take about 75 grams of protein each day to keep up with your body's needs and avoid "protein canibalization", when your body burns muscle tissue to meet its needs. During base training or strength training when you do want to add some lean muscle mass, you will need to increase protein intake to about 3/4 gram per pound of bodywieght.
This means that you will want to forget the 65-70% carbohydrate diet that is still being pushed by "experts" as an ideal diet for endurance athletes. A more realistic ratio that will meet your body's needs is closer to 50% carbohydrates, 40% protein and 10% fat.
Adjusting your diet to include more protein will pay big dividends in your performance and especially recovery. It will also help keep you from getting hungary every two hours. Try it for 60 days and judge the results for yourself.
Research confirms it
In case you were wondering what kind of documentation there is to support my ideas about protein requirements, you're in luck. In 1992 Richard Kreider, Ph.D. presented his findings on protein needs of endurance athletes to the American College of Sports Medicine. His research indicated that athletes do break down muscle tissue during intense endurance training. furthermore, he demonstrated that replacing the protein had a positive effect on fatigue, moodiness and the immune system. Kreider, who is director of the Wellness Institute and Research Center at Old Dominion University in Norfolk Virginia, studied the effects of hard training on protein breakdown, mood disturbances and immune status in college swimmers. Since the research was funded by a company that sells amino acids, the protein source used in the research was a group of 3 amino acids called "Branched Chain" or BCAA's.
After a month of training, the swimmers who had used the protein supplement experienced less muscle breakdown than the placebo group. By measuring nitrogen waste levels, which is a by product of muscle tissue breakdown, the research showed that the levels were 37% lower in the swimmers who used a protein supplement compared to those who took a placebo. Additionally, the swimmers who used the protein experienced less mood swings and improved immune response.
John Ivy, Ph.D. of the University of Texas at Austin also did a study which examined protein given after endurance exercise. His test involved cyclists doing a 2 hour time trial, then immediately after the time trial, each cyclist was given one of three mixtures; Carbohydrates, protein or a combination of the two. Blood samples and muscle biopsies revealed that the carbohydrate-protein combination produced muscle glycogen 38% faster than the carbohydrate alone. Protein only produced glycogen at the slowest rate.
These studies and other research demonstrates that endurance athletes in heavy training need about 50% more protein than recreational athletes. Specifically, this translates to .54 grams of protein per pound of body weight. So if you weigh 165 pounds, multiply that times .54 and you come up with 89.1 grams of protein as your daily requirement. This is more than twice the USRDA for adults and is probably quite a bit more than you are accustomed to eating. Also keep in mind that this amount of protein is only for maintaining the muscle mass you currently have. If you want to add muscle, in the off season for instance, you will need to increase your protein intake to .75 grams per pound of body weight to get the most out of your strength training.
Now that you know you are suffering from a protein deficiency in your diet, what are you going to do about it? You basically have two options; You can start using protein supplements or change your diet.
