Data are from Daedalus project; see the reference below.
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,
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).
