Competition Winner - Well Done Stephen
Last week's competition winner is Stephen who plays badminton competitvely. Stephen, I'll be e-mailing you again later with an evaluation form so we can get to work designing your 3-month program!
Thanks to everyone else who took the time to e-mail feedback for issue 001. Much appreciated.
For those of you who missed the chance for a custom-made, 3-month training program (complete with animated exercise images), next issue's competition will feature the same first prize. Only next time, there'll be more than one winner...
Sport Specific Articles - Send Your Requests Now
In early February Sport Fitness Advisor will be updated with some much needed sport-specific training plans and articles. I've spent the first half of January writing and comissioning articles for baseball, basketball, football, golf, hockey, ice hockey, marathon, soccer, tennis and volleyball.
Following those - articles for boxing, cycling, lacrosse, martial arts, rowing, swimming, triathlon, track & field and wrestling will be uploaded.
But I know that doesn't cover every sport.
I know it can be frustrating if your sport never gets any attention simply because it's less well-known. So...
Tell me what you'd like to see on the site - strength training for canoeists? Increasing anaerobic threshold for cross country skiing or perhaps improving grip strength in climbers?
Now is the best time to submit your request...
Elite Sports Nutrition - Eating (and Drinking) to Maximize Every Aspect of Your Performance
PART 2 - Exactly How Much Protein do Athletes need?
In the first instalment of this mini-series we touched on the nutritional requirements of athletes - and not just professional athletes. If you missed that article, in short...
Competitive sport places significant energy demands on your body. Fail to meet those demands adequately by adjusting your diet, and your performance suffers.
If you lift weights as part of your training, diet plays at least a 50% part in strength and weight gains (some will argue more).
If you're an endurance athlete, the stakes are just the same. How you refuel before, during and after an event can literally make the difference between finishing or not - let alone how high you place.
There is no sport and no event that isn't affected by your nutritional status. If you spend several hours training hard each week, it's criminal not to take just a little time to check your diet. And as we'll see in a moment, the recommendations from the Sports Nutritional field are easy to implement.
Before we try to unravel the great protein debate let's quickly look at how you can gauge your own energy expenditure...
How Many Calories do You Need? There are hundreds of formulae to estimate your daily caloric needs. Some simply ask for weight, height and age. Others ask you to fill in the number of hours you spend sleeping, your body fat percentage... even whether you're an amputee. It all starts to get a bit complicated. Not only that...
The estimations vary wildly.
I did a quick search for "calorie calculators" at Google and plugged in my own vital statistics at 10 different sites. The results?
According to one formula I need just 1985Kcals to maintain my weight. That takes into account my heavy activity and my age. I doubt it! At the other end of the scale I require over 3200Kcals to maintain my weight.
That's a huge difference.
The only truly accurate method is to keep a food diary. It's a lot less hassle than it sounds. Keep a record for 3 days (or up to a week) of everything that passes your lips. At the end of each day jot down each meal, snack and drink and the approximate sizes i.e. 2 cups of pasta, 1 medium banana etc.
Now add up the total amount of calories for each day - you can find calories tables easily on the Net. Microsoft Encarta also includes the calorie content of thousands of foods. Here's an example: www.annecollins.com/calories/
As long as your weight isn't fluctuating at the moment, you'll have a good idea of how many calories you need to maintain your weight.
If you want to gain weight or strength in conjunction with a weights program, add 500kcals to your daily requirement. In order to build muscle you need a surplus of energy over and above your daily requirements.
Talking of strength training and building muscle...
How Much Protein do You Need? Correct and adequate protein intake is crucial for anyone involved in vigorous training. To understand why though, we need brush on some basic chemistry...
Every protein molecule is formed by building blocks called amino acids.
The body requires 20 amino acids in total. In adults, 8 of those 20 amino acids must be derived from food - the body cannot synthesize them itself - so they are given the name essential amino acids.
Why is that important to you as an athlete?
In order for muscle tissue to grow and repair you have to consume all 8 essential amino acids in their correct ratio. How do you do that?
By consuming foods that are complete proteins.
Milk, eggs, meat, fish and poultry are complete proteins. They contain an optimal mix of all 8 essential amino acids. Beans, peas, nuts and cereals contain protein. But they are incomplete. They lack one or more essential amino acid.
In order for vegetarians to consume all 8 essential amino acids they must eat a wide variety of vegetable based proteins.
The Recommended Dietary Allowance (RDA) for the average male and female adult is just 0.83g per kilogram of bodyweight. Take your weight in lbs and divide it by 2.2. This you weight in kgs. Multiply that figure by 0.83 to attain your RDA for protein. In a 150lb individual this equates to 57g of protein per day.
That's not much at all - about 3 chicken breasts worth.
Some research shows that competitive athletes - particularly those involved in heavy weight training may require more protein. But the emphasis is on "may".
Recommendations for daily protein intake for endurance athletes and strength athletes is 1.2-1.4g/kg and 1.6-1.7g/kg respectively. Remember, that's per kg of bodyweight not per lb.
Will your body ever breakdown protein (i.e. your muscle tissue) to use as energy?
In a word, yes - if your calorie intake falls below your requirements.
Read that line carefully again.
It is not a lack of protein that forces the body to breakdown lean tissue for use as energy - it is a lack of calories.
Eating additional protein over and above the 1.6 - 1.7g per kg RDA will not increase lean mass - even in strength athletes. Eating more calories will.
In fact eating protein in amounts way above the RDA can be dangerous. The kidneys must eliminate the by-product of protein digestion, Uric acid. Over time a high protein intake may place an unnatural burden on the liver and kidneys.
It can negatively affect performance as well. Every gram of urea expelled in urine is accompanied by 50mL of water increasing the chances of dehydration during prolonged activity.
If a high-protein diet substitutes a high-carbohydrate diet (which we'll cover next issue) performance can be dramatically hindered...
Carbohydrate is always the first source of fuel your body uses for energy. It's broken down and absorbed much more rapidly than protein (and fat) allowing for a higher intensity of work rate over a longer period of time.
As for Protein Supplements...
Consider this interesting, recent study by Rozenek et al (2002)...
73 healthy males were split into 3 groups.
Group A was given a high calorie, carbohydrate and protein supplement to take each day (containing 106g of protein!).
Group B were given the same high calorie supplement which consisted only of carbohydrate and no protein.
Group C were the control and took nothing. All the groups' regular diets were monitored and remained unchanged over the course of the study.
After 8 weeks of resistance training Groups A and B (who took the high calorie supplement) increased their body mass and lean muscle mass significantly more than Group C (who's caloric intake stayed the same). So additional calories really are important for strength and weight gain. However...
Group A (lots of protein) gained no additional weight and no more strength than group B who took no additional protein. Group B's protein intake fell within the RDA guidelines above.
Granted, there are too few studies into the effects of high-protein diet on strength gain. Nevertheless, those that have been conducted have yet to show that it is in any way advantageous.
So to sum up...
In Part 3 of Elite Sports Nutrition we'll look at carbohydrate's role in performance and the ideal pre and post competition meal. We'll also look at re-hydration and isotonic sports drinks - are they really anything special?
Delayed onset muscle soreness (DOMS) is a familiar experience most of us...
It's that sensation of discomfort that occurs 1 to 2 days after training and can range from slight tenderness to debilitating pain! It usually occurs if you've engaged in an activity that's new to you or when you haven't engaged in the activity for some period of time...
The first training session after the off-season is a classic example. Or returning to a heavy weight training routine following a Christmas break.
DOMS, if it does occur, will usually happen about 12 to 48 hours after the event. Symptoms often feel at their worst some 2 days later and will include overall body soreness, tiredness, weak and stiff muscles.
As you get used to the exercise again over a period of weeks, these delayed symptoms will gradually disappear, although you may still feel some soreness after particularly demanding sessions.
What Causes DOMS?
Up to six hypothesised theories have been proposed for the mechanism of DOMS. They are:
What happened to being just "stiff and sore" - sounds much less dramatic!
It appears that the extent of tearing that occurs is determined by (1) the type of exercise you participate in, (2) how long you exercised, and (3) and how strenuously you exercise.
The type of activities that are most closely linked with DOMS are those which cause muscles to contract eccentrically...
When a muscle contracts and lengthens at the same time it is said to be contracting eccentrically - slowly lowering a dumbbell to fully extend your arm in a bicep curl is a good example.
Other activities that stress the musculature eccentrically include... walking down stairs, running down a hill, any lowering of weights, or the downward movement of concentrated exercises such as squats.
Can the Delayed Onset Muscle Soreness Be Prevented?
It's also important that you remember to cool down completely after the activity is over. Whether this really can limit delayed muscle soreness is yet to be established but it certainly won't do any harm.
If you are starting a weights program, take the time to build up the resistance and number of sets and repetitions over several weeks. In fact this applies to any strenuous exercise program. Trying to progress too quickly will not only increase the risk of delayed muscle soreness but injury too. If you take the time to plan out your program in the off-season you'll by-pass the urge to skip ahead to more intense workouts.
Recovering from Delayed Onset Muscle Soreness
Massage therapy has shown some positive results that may be attributed to the time of massage application and the type of massage technique used.
Cryotherapy (ice baths or ice packs), stretching, homeopathy, ultrasound and electrical current modalities have demonstrated no effect in clinical trials, yet athletes still use them as a matter of routine.
Gentle exercise is the most effective means of alleviating pain during DOMS, however the analgesic effect is also temporary.
As an athlete, if you must train on a daily basis, reduce the intensity and duration of exercise for 1-2 days following intense DOMS-inducing exercise.
Here are a few other techniques that may work...
The experimental group demonstrated significantly superior recovery of contractile function and diminished strength from DOMS after downhill running when compared with a placebo group. A proven method for preventing and relieving DOMS would certainly be useful for most athletes in the early pre-season phase of training.
I'll keep my eye out for any further research in this area and keep you posted.
Circuit Training for Athletic Functional Strength & Strength Endurance
Circuit training is one of the most efficient training modes to improve sport-specific strength and endurance.
When are professional athletes most likely to use circuit training?
