Calculates an estimated vo2 max for a given distance and duration (race effort)

Returns a float

examples

Examples

iex> estimated_vo2max(5000, 1080) # 18 minute 5k 56.319480966731284

Calculates race time predictions for many different race distances based on vo2max

Returns a map of distance (in meters) to time (in seconds)

examples

Examples

iex> predict_all_race_times(61)
%{distance => time}

Calculates a predicted race time using vo2max and a distance.

Returns the duration (in seconds) for the given distance.

Examples

iex> predict_race_time(42_195, 61) |> Squeeze.Duration.format() "2:41:03"

Calculates the velocity (meters/sec) for a given vo2max and percentage.

Say easy pace is between 65% to 70% of your vo2max pace (50). You can use this like the following:

iex> velocity_at_vo2max_percentage(50, 0.65)
3.06818475 # meters per second (8:44 min/mile)
