Oxygen uptake versus mechanical power, for humans

Description

Data are from Daedalus project; see the reference below.

Usage

data(humanpower1)

Format

A data frame with 28 observations on the following 3 variables.

wattsPerKg

a numeric vector: watts per kilogram of body weight

o2

a numeric vector: ml/min/kg

id

a factor with levels 1 - 5 (humanpower1) or 1 - 4 (humanpower2), identifying the different athletes

Details

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).
