R Dataset / Package DAAG / humanpower2


On this R-data 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. You can load the humanpower2 data set in R by issuing the following command at the console data("humanpower2"). This will 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. 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 (humanpower1) or 1 - 4 (humanpower2), identifying the different athletes


Data in 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, Data in humanpower2) are for four out of the 25 applicants who were selected for further testing, in the lead-up to the eventual selection of a pilot for the Daedalus project (Nadel and Bussolari 1988).
