About

Cardiorespiratory fitness (CRF) is a physical attribute which represents how effectively various bodily systems work together to transport and utilize oxygen to support muscular activity during prolonged, rhythmic, large-muscle, whole-body exercise. A key element associated with physical fitness is VO2max, which is referred to as cardiorespiratory fitness. Queen's college step test will be used to estimate the VO2max. This study will be cross sectional, normative study. Healthy adults aged 18-65 years from community setting will be recruited through non probability convenient sampling technique to collect data as per inclusion criteria. Sample size will be approximately 800, consist of equal ratio of males and females. Heart Rate, Recovery Heart Rate, VO2 max and METS will be calculated of each subject. Following equation is used to calculate VO2max, for females: VO2max = 65.81- [0.1847× HR] for males: VO2max = 111.33- [0.42× HR]. Data analysis will be conducted by using SPSS (Statistical Package for the Social Sciences) version 28.

Full description

Cardiorespiratory fitness (CRF) is a physical attribute which represents how effectively various bodily systems work together to transport and utilize oxygen to support muscular activity during prolonged, rhythmic, large-muscle, whole-body exercise. A key element associated with physical fitness is VO2max, which is referred to as cardiorespiratory fitness. Queen's college step test (reliability = 0.92, validity = 0.75) will be used to estimate the VO2max. The objectives of the study is to obtain the normative reference values for cardiorespiratory fitness in healthy pakistani adults.

This study will be cross sectional, normative study. Healthy adults aged 18-65 years from community setting will be recruited through non probability convenient sampling technique to collect data as per inclusion criteria. Sample size will be approximately 800, consist of equal ratio of males and females. Heart Rate, Recovery Heart Rate, VO2 max and METS will be calculated of each subject. Following equation is used to calculate VO2max, for females: VO2max = 65.81- [0.1847× HR] for males: VO2max = 111.33- [0.42× HR]. Demographics include Age (years), Height (m2), Weight (kg) and Body Mass Index (BMI kg/m2) will be measure for each subject.Data analysis will be conducted by using SPSS (Statistical Package for the Social Sciences) version 28.
