I DO NOT UNDERSTAND V02 MAX

vO2max is the maximum volume of oxygen delivered to, and used by, your muscles.

You would need to actually do a VO2 max test in order for someone to truly tell you what your max is. This usually involves some form of indirect calorimetry such as a metabolic cart, connected to tubes that collect and measure both inspired/expired air in order to determine the amount of oxygen consumed by your working muscles. The range is usually between 4.0-6.0L/min, and is often expressed relative to your body mass (in kg) in order to compare different individuals/sexes and to standardize for muscle mass.

There are websites that can give you an estimate from some of these values (1600m is probably the best to use). However, as noted to know a "true" value, a lab test with a met cart is needed.

But how can you know if the numbers are accurate? How can you know if the athlete has truly reached maximum heart rate?

And

what is the relationship between stroke volume and plasma volume?

what is the relationship between stroke volume and heart rate?

Thanks.

You don't need to understand any of this terminology. Just run baby.

I understand the terminology, you're kind of missing the point here. This stuff is not understood by physiologists coaches or athletes.

Just run baby is not an answer to beating current world records without drugs baby.

You can't qccurately predict your VO2 max off these workouts. Running these same workouts weighing even 5 lbs less will effect your VO2 max. It is the amount of oxygen your body can utilize relative to body weight. Having an ability to perform better at lactate threshold and beyond will help you have better times with a lesser VO2 max. In most aspects VO2 max is useless from a practical standpoint.

according to joe vigil your vo2 max is your 1600pr so for you that would be 4:58 mile pace. For example you could do 12x400 at 74-75 with 75 sec recovery or 5-6x800 at 2:29 with 2;30 recovery. I would not go above 1/2 mile pieces since 4:58 is your all out mile pace. 1:1 work to rest ratio.

If you want to be more traditional in your vo2 max application then 4:58 would represent 110% in an inverse variation since the 1600 is 110% of vo2 max. Therefore 100% would be 5:27.8 1600 pace. [298*1.1 = 327.8] This now assumes you would race just under 11min for 2 miles. Workouts would include: 3xmile at 5:27 with 5min rest. 6x1/2mile at 2:44 with 2:30 rest. Also, you could do 1000s or 1200s with equal rest. Once again the work to rest ratio is 1:1.

Pure BS.

You provide a good definition. VO2max appears to sometimes be interchangeably used with Velocity at VO2max (vVO2max), which can be confusing to the uninitiated.

Thanks.

When plasma volume increases, as what happens when someone is endurance trained, your total blood volume expands. This increases venous return, or the volume of blood returning to the heart. This will increase end-diastolic volume (EDV), or the volume of blood the ventricle holds before it pumps it out. The greater the EDV, the greater the stroke volume.

When stroke volume increases, heart rate will decrease. This is mainly why endurance-trained athletes have low resting heart rates. Because stroke volume is large, the heart doesn't have to beat as fast to provide the same cardiac output. So, heart rate slows. This is called bradycardia.

Put these two together to deduce that if plasma volume increases, heart rate decreases, and vice-versa. When you're dehydrated, plasma volume drops, so your blood volume drops. That means stroke volume drops. In order to maintain cardiac output, heart rate will increase.

Thanks, I almost had a stroke when I saw him type that physiologists didn't understand these basic concepts.

Do Balke test

if it is Pure BS- to which I disagree- why dont you offer a better application of Vo2 max?

for a high school athlete simply running a 3200 will give them an accurate view of their Vo2 Max. 3200m. = 100% of Vo2 Max

There is no better application as i said in my above post. It is entirely worthless and has no practical application to training or improvement in performance. You can't predict your VO2 max from a 1600m run as there are far too many other variables that change it. It is strictly an absolute that can only be measured with a metabolic cart and can even vary depending on the activity you are performing during the test...i.e. a runner would likely achieve a lower Vo2 max during cycle ergometry and vice versa. In grad school for an ex phys research project, me and my friend, who ran D2 cross, got the entire xc team to do the Bruce protocol for Vo2 max testing. There was no correlation between the xc runners vo2 max and times or places from their most recent race. In fact, the best runner was mid pack vo2 max and i think i remember their being about 20 ml/kg/min between the best and worst.

Heart rate is basically the same thing. Dont overcomplicate things.

Perhaps the better question is what do you want to know? Or why do you want to know it? What would you do with your VO2max value, if you knew it?

The lab room definition of VO2max is the maximum volume of oxygen you can consume in 1 minute (L/min). Usually it is "normalized" by dividing by your weight (ml/min/kg).

The basic idea is that more oxygen consumption per minute translates into more energy production per minute, and more energy leads to faster times. It is an indirect measure of performance potential (but not a very good one). If you have a low VO2max, you want to increase it, but this is not the only goal. You want a relatively high VO2max, but your "maximum" VO2max is not necessarily the "optimal" VO2max value.

VO2max has problems. First, it is not easy to measure accurately. And second, an accurate measurement is not that useful, as it can vary greatly between equal performing athletes. You can compare absolute values with yourself, but not so much with other athletes. A major reason for this has to do with running efficiency (how much energy produced goes to your legs) and running economy (how the energy produced translates to speed). When you have a good running economy, you consume less oxygen to achieve the same speed.

As previously mentioned, your pace at your VO2max is more interesting than your oxygen consumption at VO2max.

A better value for training purposes, which is easier and cheaper to measure, and pace oriented, is Jack Daniels VDOT. It looks like VO2max, but is really a race time in disguise, just "normalized" for distance, and scaled to look like VO2max. With this VDOT value, you can compare performances at different distances, and determine suitable training paces.

From your 1600m time, your VDOT is 59. From your 5000m time, your VDOT is 54. From your 800m time, your VDOT is 63. Note that VDOT, being a pseudo "aerobic" metric, becomes less accurate for middle and short distances. Your 800m VDOT is higher, due to non-aerobic energy contribution.

You might be tempted to conclude that a broad range of 54-63 is too broad to be useful, but VDOT can also help you determine which event is weaker and where you might want to develop. From this we can see that your 5K time is weaker than your other times. This might be normal if you are a natural middle distance runner, but it might also be a sign that you should work on endurance.

Heart rate and VO2 Max are not even close to the same thing
