Description

Compares physical functional performance to the age- and gender-specific normal range scores from the Rikli and Jones Senior Fitness Test Manual. Note that the manual provides normative values for seriors aged between 60-94. Comparison to the norms will only be performed for individuals aged between 60 to 94.

Usage

Arguments

data

Data frame which consists of six columns:

Column 1: Age
Column 2: Gender (F: female, M: male)
Column 3: Number of Steps
Column 4: Number of full stands
Column 5: Mean of 8 foot up and go trials
Column 6: Mean of left and right armcurls

Value

Four additional columns [StepsNorm, StandNorm, UpgoNorm, ArmcurlNorm] are provided, to the data supplied to the function. The columns indicate whether the individuals' physical performance meets the norm or is lower or higher than the norm.
