Brief summary
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.
Detailed 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Queen's college step test | one time point | QCST will be used to estimate the VO2max. The step test will be performed using a tool of 16.25 inches height. Stepping will be performed for a total duration of 3 minutes at the rate of 22 steps per minute for females and 24 steps per minute for males which will be set by a metronome. After completing the stepping , the subject remains standing, wait 5 seconds, take a 15s heart rate count and multiply the HR by 4 to convert into beats per minute. following equation is used to predict VO2max. For females: VO2max = 65.81- \[0.1847× HR\] For males: VO2max = 111.33- \[0.42× HR\] The reliability and validity of queen's college step test is 0.92 and 0.75 respectively. |
| pulse oximeter | one time point | Heart rate will be calculated by pulse oximeter. After completing the stepping , the subject remains standing, wait 5 seconds, take a 15s heart rate count and multiply the HR by 4 to convert into beats per minute. |
| Recovery Heart Rate | one time point | Recovery heart rate will be measure by substracting the heart rate after 1 minute from the peak heart rate which will be compare with standard values to check the heart health. |
| METS | one time point | Metabolic equivalents of task (METS) will be calculated dividing VO2max by 3.5ml/kg/min. METS = VO2 MAX ÷ 3.5 ml/kg/min |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| weighing machine | one time point | weight (kg) will be measure through weighing machine |
| Body Mass Index | one time point | BMI will be calculated dividing weight by height (m2). |
| stadiometer | one time point | height (m2) will be measure through stadiometer |
