KINE 303 Palomar College VO2 Maximum Estimation Lab Report

You need to read a lap report (VO2 max estimation results) and base on that answer 2questions.

1. Write-up the data in a brief paragraph, reporting on the mean and standard deviation, mode, and range of the VO2max values. Please include an introductory sentence as well as a brief conclusion.

2. How do your peers’ estimates of VO2max compare to normal values for young men and women (consult Google)? Explain any discrepancies between your values and these age- and sex-matched norms.

KINE 303—VO2max estimation lab (due in 1 week)
Data from various tests and assessments can be expressed in several different ways, the easiest of
which is called descriptive statistics. As the name implies, they merely describe the data, usually
to present the average score, the most common score, and the range of scores. Widely-used
descriptive statistics include…
a) Mean (X): the average of all participants’ scores i.e. the sum of all scores divided by the
number of scores or observations
b) median: the middle or midpoint of all scores
c) range: the difference between the highest and lowest score
d) mode: the most common score
e) standard deviation (SD): the ‘spread’ or variability in (sets of) scores
f) skewness (the shape of the distribution) and kurtosis (amplitude of the distribution)
These statistics (with the exception of skewness and kurtosis) can be calculated by hand, but
using the program SPSS, we will allow the computer to do so. Nevertheless, it is important to
know what each statistic means and how they are obtained.
It is often necessary to examine the distribution of scores, to determine if they are normally
distributed i.e. scores do not fall outside a given SD from the mean. This is important, as more
advanced statistics are based on the premise of normally distributed data. In this lab, we will
examine the histogram as well as the frequency polygon (distribution) to more closely
examine the distribution of scores.
Procedures: I have provided all of you the link to estimate your cardiorespiratory fitness
(VO2max) via the NTNU website. VO2max is related to endurance performance and is inversely
linked to health status, as individuals who are inactive tend to have low VO2max and in turn,
enhanced risk of cardiovascular disease, diabetes, stroke, etc. This link has been administered to
thousands of individuals worldwide to elicit a relatively accurate estimate of VO2max, which is
typically assessed in a lab setting requiring expensive equipment, trained clinicians, and exercise
to exhaustion. Please provide this value to me as well as your age, body mass index in kg/m2
(divide your mass in kg by height in m2), body fat percent using the handheld device, and current
voluntary physical activity in hours/week (this does not include work, chores, etc. and only
includes engaging in various forms of exercise to improve fitness).
Data Analysis: Once you provide me the results, I will de-identify the data and make them
accessible on Cougar Courses as an Excel file. In class, we will open them in SPSS. Make sure
to put this file on your ‘h’ drive or other drive so you can access them in class. We will run
descriptive/frequency statistics as well as a histogram to examine the data, as shown in the text
as well as by me in class.
Questions etc. (due one week after we analyze the data)
1. Use SPSS to calculate mean/median/range/standard deviation statistics for participants’
VO2max, and present them in a Table with a proper title and number.
2. Using the histogram, describe the shape of the distribution for VO2max. Was it normally
distributed?
3. What did the frequency distribution tell us about the diversity of VO2max values in your
class?
4. Write-up the data in a brief paragraph, reporting on the mean and standard deviation, mode,
and range of the VO2max values. Please include an introductory sentence as well as a brief
conclusion.
5. Cite any limitations or errors in this laboratory.
6. Denote one null and one directional hypothesis applicable to this lab and methods used to
acquire the data. Were they supported based upon our data?
7. How do your peers’ estimates of VO2max compare to normal values for young men and
women (consult Google)? Explain any discrepancies between your values and these age- and
sex-matched norms.
