On this Picostat.com statistics page, you will find information about the humanpower2 data set which pertains to Oxygen uptake versus mechanical power, for humans. The humanpower2 data set is found in the DAAG R package. Try to load the humanpower2 data set in R by issuing the following command at the console data("humanpower2"). This may load the data into a variable called humanpower2. If R says the humanpower2 data set is not found, you can try installing the package by issuing this command install.packages("DAAG") and then attempt to reload the data with library("DAAG") followed by data("humanpower2"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing humanpower2 at the command-line which should display the entire dataset.
If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the humanpower2 R data set. The size of this file is about 409 bytes.
Oxygen uptake versus mechanical power, for humans
The data set from Daedalus project.
A data frame with 28 observations on the following 3 variables.
a numeric vector: watts per kilogram of body weight
a numeric vector: ml/min/kg
a factor with levels 1 - 5 (
or 1 - 4 (
humanpower2), identifying the different athletes
humanpower1 are from investigations (Bussolari 1987)
designed to assess the feasibility of a proposed 119 kilometer human
powered flight from the island of Crete – in the initial phase of the
Daedalus project. Data are for five athletes
– a female hockey player, a male amateur tri-athlete, a female
amateur triathlete, a male wrestler and a male cyclist – who were
selected from volunteers who were recruited through the news media,

were selected for further testing, in the lead-up to the eventual
selection of a pilot for the Daedalus project (Nadel and Bussolari 1988).
