How does this peak flow calculator work?
This is a quick health tool that determines the estimated or predicted peak flow based on your data. https://truelfile302.weebly.com/bar-tipping-etiquette.html.
You need to select your gender and input your age and height. The former can be put in either metric (cm) or English (inches) measurement.
Enter 1 in the distance box and choose miles from its menu. Click CALCULATE and your answer is 53.6 years (as well as 11 other units). 3) You are watching the Indianapolis 500 Auto Race and a car has just taken 50 seconds to complete one 'lap' of the track at 180 miles per hour. We're now sending you PeakHour 4 which you are welcome to try for 10 days. If you decide to upgrade, make sure you have the latest PeakHour 3 installed and activated. If you need your PeakHour 3 license key, you can recover your license. Thus, if it's 4 miles to the summit, and you backtrack over your same trail, you should enter 8 here. Elevation Gain: This is not the elevation at the summit. That number is the vertical distance from sea level.
If you already have a peak flow determination you can input that as well to get an extra info in the result. Recordam 1 3 download free.
Based on peak flow formulas, the calculator computes the predicted value in your case and extracts the percentage the measured figure is out of the prediction. You can use the form as many times as you like varying the information or personal data. Calendarpro for google 2 2 4 – google calendar application.
Example calculation:
■ Let's take for instance the case of a female aged 32 with a height of 175cm. Her estimated peak flow value would be 467.4 L/min.
■ Or in the case of a male aged 27 with a height of 186 cm. His predicted peak flow value would be 639.948 L/min. But if he already has a measured peak flow of 568 L/min, the percentage is 88.76.

Quantitative definitions[edit]
Based on oxygen utilization and body mass[edit]
The original definition of metabolic equivalent of task is the oxygen used by a person in milliliters per minute per kilogram body mass divided by 3.5.
Other definitions which roughly produce the same numbers have been devised, such as:
- 1 MET=1kcalkg×h=4186.8Jkg×h=1.163Wkg{displaystyle {text{1 MET}} =1,{frac {text{kcal}}{{text{kg}}times {text{h}}}} =4186.8,{frac {text{J}}{{text{kg}}times {text{h}}}}=1.163,{frac {text{W}}{text{kg}}}}
where
- kcal = kilocalorie
- kg = kilogram
- h = hour
- J = joule
- W = watt
Based on watts produced and body surface area[edit]
Still another definition of 1 MET is 58.2 W/m2 (18.4 Btu/h·ft2), which is equal to the rate of energy produced per unit surface area of an average person seated at rest. The surface area of an average person is 1.8 m2 (19 ft2). Metabolic rate is usually expressed in terms of unit area of the total body surface (ANSI/ASHRAE Standard 55[1]).
Based on resting metabolic rate[edit]
1.8 Hours Equals
Originally, 1 MET was considered as the resting metabolic rate (RMR) obtained during quiet sitting.[2][3]
Although the RMR of any person may deviate from the reference value, MET can be thought of as an index of the intensity of activities: for example, an activity with a MET value of 2, such as walking at a slow pace (e.g., 3 km/h) would require twice the energy that an average person consumes at rest (e.g., sitting quietly).[4][5]
Use[edit]
MET: The ratio of the work metabolic rate to the resting metabolic rate. One MET is defined as 1 kcal/kg/hour and is roughly equivalent to the energy cost of sitting quietly. A MET also is defined as oxygen uptake in ml/kg/min with one MET equal to the oxygen cost of sitting quietly, equivalent to 3.5 ml/kg/min. The MET concept was primarily designed to be used in epidemiological surveys, where survey respondents answer the amount of time they spend for specific physical activities.[3]MET is used to provide general medical thresholds and guidelines to a population.[6][7] A MET is the ratio of the rate of energy expended during an activity to the rate of energy expended at rest. For example, 1 MET is the rate of energy expenditure while at rest. A 4 MET activity expends 4 times the energy used by the body at rest. If a person does a 4 MET activity for 30 minutes, he or she has done 4 x 30 = 120 MET-minutes (or 2.0 MET-hours) of physical activity. A person could also achieve 120 MET-minutes by doing an 8 MET activity for 15 minutes.[8]

In a systematic review of physical activity and major chronic diseases, a meta‐analysis of 11.25 MET h/week increase in physical activity yielded: 23% lower risk of cardiovascular disease mortality (RR=0.77, 95% Confidence interval 0.71-0.84), and 26% lower risk of type 2 diabetes (0.74 RR, 95% CI, 0.77–0.72).[9]
Exercise guidelines[edit]
The American College of Sports Medicine and American Heart Association guidelines count periods of at least 10 minutes of moderate MET level activity towards their recommended daily amounts of exercise. For healthy adults aged 18 to 65, the guidelines recommend moderate exercise for 30 minutes five days a week, or vigorous aerobic exercise for 20 minutes three days a week.[10]

Limitations[edit]
The definition of MET is problematic when used for specific persons.[4][5] By convention, 1 MET is considered equivalent to the consumption of 3.5 ml O2·kg−1·min−1 (or 3.5 ml of oxygen per kilogram of body mass per minute) and is roughly equivalent to the expenditure of 1 kcal per kilogram of body weight per hour. This value was first experimentally derived from the resting oxygen consumption of a particular subject (a healthy 40-year-old, 70 kg man) and must therefore be treated as a convention. Since the RMR of a person depends mainly on lean body mass (and not total weight) and other physiological factors such as health status, age, etc., actual RMR (and thus 1-MET energy equivalents) may vary significantly from the kcal/(kg·h) rule of thumb. RMR measurements by calorimetry in medical surveys have shown that the conventional 1-MET value overestimates the actual resting O2 consumption and energy expenditures by about 20% to 30% on the average, whereas body composition (ratio of body fat to lean body mass) accounted for most of the variance.[4][5]
Standardized definition for research[edit]
The Compendium of Physical Activities was developed for use in epidemiologic studies to standardize the assignment of MET intensities in physical activity questionnaires. Dr. Bill Haskell from Stanford University conceptualized the compendium and developed a prototype for the document. The compendium was used first in the Survey of Activity, Fitness, and Exercise (SAFE study – 1987 to 1989) to code and score physical activity records. Since then, the compendium has been used in studies worldwide to assign intensity units to physical activity questionnaires and to develop innovative ways to assess energy expenditure in physical activity studies. The compendium was published in 1993 and updated in 2000 and 2011.[15][16]
