VO2 MAX - What, Why, How, When
 

What is VO2 MAX?  This is a measurement of the maximum amount of oxygen your body can use and is dependent on three basic variables:

 
1) The total amount of oxygen that is delivered to the working muscles.
2) The total amount of oxygen extracted and utilized by the working muscles.
3) The efficacy of the muscles cells and circulatory system to expell carbon dioxide and lactate.
 
Why measure VO2 MAX? VO2 Max is quantified in milliiters/kilogram/minute, ml/kg/min. For runners without a personal exercise physiologist and human performance lab readily available, this number is not very helpful.  Knowing ones running pace when working at VO2 Max, however, can help structure a running  program to more efficiently progress in speed and endurance. This pace is known as vVO2, the velocity sustained at VO2 Max.
 
How do you measure vVO2?  VO2 Max is most accurately measured in a lab where actual levels of oxygen are quantified.  vVO2, the more important number for us, can be attained in a more convenient manner, a 2 mile best effort run. If run truly at best effort, and with minimal to no inhibiting weather/course conditions (wind, heat, hills, etc.) this pace, measure in minutes per mile, has you working at VO2 Max within a 5% margin of error.
 
When do I consider my vVO2 for designing workouts?
Improving your vVO2, and subsequently your VO2 Max, is an important element in the development of a runner as it often equates to an increased running economy (the ability to run at race paces with less effort).  Running intervals 3-5 minutes in length and 95-100% of vVO2 is a standard approach, though exact lengths and percentages do vary in consideration of personal factors (running programs, genetics, general fitness levels, goals, etc). Focusing on this sort of training should be done once per week for 12-14 weeks.

EAT AND RUN! What you need to know about nutrition before pounding the pavement. (part 2 of a 4 part series)
 
While improvements in your overall diet can boost your athletic performance, the pre-workout meal is a key piece to optimal performance. Whether it's before the main event or training, the food ingested hours beforehand may make or break you. While many runners decide to skip the pre-workout and during-workout meals in an attempt to lose weight and cut calories, the nutrients provided are vital to optimal performance. Additionally, runners who choose to skip the pre-workout meal will inevitably consume those missed calories later in the day. If you can't train to your best ability, how are you going to reach your peak performance when it comes to race day? So why not put the calories towards a solid workout to help take your running to the next level.

What to eat:

There are the three main nutrients that one should pay careful attention to in the pre-workout meal - carbohydrates (including fiber), protein and fat. The most important pre-workout nutrient to fuel your muscles is carbohydrate. While having a small amount of protein and fat thrown in for satiety is ok- eating sufficient carbohydrate is key to replenish the quick energy that our body uses during exercise - glycogen. Carbohydrates are also easily digested and will not cause stomach disturbances when eaten shortly before training. Carbohydrates also help to absorb electrolytes and minerals important for muscle contraction and nerve stimulation. The table below provides some ideas for high carbohydrate foods. The line below includes additional nutritional benefits.

50-60% of your day's calories should come from Carbohydrate Maximize your workout with these foods!

· Banana - Carbohydrate, potassium and vitamin C Potassium - assists in muscle contraction and in maintaining fluid and electrolyte balance in body cells - assists in pulling energy from protein fat.
· Yogurt (lowfat or skim) - Calcium, protein, active cultures Lactobacillus acidophilus, L. casei, L. reuteri and Bifidobacterium bifidum - maintain a healthy gastrointestinal tract.
* Other carb foods include breads, pastas, rices, cereals, grains, starchy veggies, fruits, beans and lentils, juice and milk.

How Carbohydrate works for the athlete::

As stated previously, carbohydrates function to restock glycogen - the technical term for the bodies' stored sugar source - in the muscle and liver. When there is too much energy/glycogen around, it gets stored as fat (which we unfortunately can store unlimited quantities of). During exercise glycogen gets . . .full article

 
WEIGHT TRAINING FOR RUNNERS part I
 

To some runners the idea of weight training is out of the question - the false idea that weight training results in big bulky muscles.  There are many different methods to weight training and for runners this becomes very important to consider.   Let's look at aspects of two contrasting weight training programs, one bad and one good for runners.

 

#1: Lifting for gains in girth (big bulky muscles)
· 3-6 sets of 2-8 repetitions for each exercise
· 3-4 exercises for each body part
· All body parts are worked out 1-2 times per week and with equal importance

 

This program is meant for those interested in body-building.  Nearly every set, aside from a warm-up set not mentioned, is to complete or near complete failure.   What endurance runner would do this program?  None and perhaps none have.  But the training effects of this program do occur in less intense programs and these are often carried out by ambitious but mis-informed distance runners.   The negative results, for runners, from this type of program are as follows:

1) The gain in girth is extra weight to carry around which only makes it harder to run faster for long periods of time.
2) The dramatic gain in strength results in loss of flexibility which results in reduced circulation, thus making it harder to run faster and farther, as well as maintain a natural running gait.
3) The gain in strength is attained through purely anaerobic energy systems (since it will take 4-20 seconds per set).  This forces certain muscle fibers (Fast twitch IIa) to work purely anaerobically (despite their capability to work in both energy systems), thus resulting in reduced recruitment of aerobic muscle fibers than what is otherwise possible. This process is most counterproductive in consideration of the lower body exercises.

#2: Lifting for runners
· 2 sets of 12-15 repetitions for most exercises
· 1-2 exercises per body parts
· All upper-body parts are worked out 2-3 times per week (lower-body 0-1 times/week - discussed next month)

· The parts important for running are focused on more. In order of importance these are:

1) Core
2) Lower Back
3) Mid-back
4) Shoulders
5) Chest
6) Arms

The point of this type of program is to gain strength in a way that can:

1) better absorb the impact forces of running (core, lower back, shoulders)
2) maintain body posture through hours of exercise (core, lower back, mid-back, chest, arms)
3) support and add power for the hamstrings, glutes, hip flexors (core, lower back)

The suggestions mentioned above are for the average runner.  Modifications should be made to account for personal strengths and weaknesses, genetics, and health history.

ILLIOTIBIAL BAND SYNDROME AND MASSAGE
One of the most common afflictions in runners is Iliotibial Band Syndrome (IT Band Syndrome) which is symptomatic of knee pain in the lateral (outside) knee.

What is the Iliotibial Band (IT Band)?

The Iliotibial Band (IT Band) is a thick layer of fascia on the lateral (outside) leg running from the hip to just below the knee. This thick fascia is vital in providing stability and support for the lower body.
 
What is IT Band Syndrome?
When the IT Band becomes excessively tight it can cause pulling on its insertion at the knee and cause mild to severe pain. The primary muscles involved in IT Band syndrome are the Gluteus Maximus and the Tensor Fasciae Latae (TFL). These muscles are important elements in running (Gluteus Maximus) and standing (TFL). When one or both of these muscles pulls the IT Band tight it causes the IT Band to exert greater pressure on its insertion at the knee, causing the bursa (fluid filled sac) under the IT Band to become inflamed and cause pain. IT Band Syndrome can be triggered by a number of things:
 
· Sudden increase in mileage
· Strenuous hill work
· Poor pelvic or foot mechanics
· Poor running shoes
· Uneven surface conditions
· Track running
 
The Benefits of Massage on preventing and treating IT Band Syndrome.
Massage is extremely beneficial in helping to prevent and or treat IT Band Syndrome. Deep tissue massage along the Gluteal muscles and the TFL can help keep these muscles loose and prevent them from pulling the IT Band tight; thereby, reducing the risk of IT Band Syndrome. Also, massage strokes that both lengthen and broaden the IT Band itself can help reduce tightness within the IT band. General massage of the muscles of the leg can bring balance to the lower body and help reduce general tightness and release restrictions in the muscle. These same techniques can be used to help treat IT Band Syndrome after its onset. After the onset of IT Band Syndrome, other treatment methods such as: icing, reducing or stopping running, correcting foot or gait mechanics, and specific stretches may also be necessary to assist in healing.
Preventative maintenance massage can be extremely beneficial to anyone who is newly training, increasing training intensity or mileage, or has poor stretching habits. Massage can bring awareness to the runner of what is going on in the body, and early awareness can bring focus to potential problem areas before they become injuries.

IN THE TRENCHES
 
Halfway through my 10k race last weekend and wow did mother nature call! I couldn't hold off any longer so I break through the shallow strand of supporters looking for an open business, Sunday 8:30 a.m. - no such luck. But instead I gaze upon a large (football field size) construction site where all that had been done thus far was the tearing up and removal of the pre-existing concrete. In the middle of the mud pit, however, was a port-o-pottie sent from god. Perhaps against my normal senses I went for it. Still in race mode I start running across and made it about 10 yards before tripping into a 3 foot ditch, mud all over my shoes, knees, and hands. Though the distance back is still far less than the goal ahead of me I continue on, walking now, with each step sinking 2-3 inches into the ground. When I finally returned to the course my stride length could easily be measured and the brand of my shoes identified as my path for the next 1/4 mile or so was clearly marked off with brown footprints. :(
