Normative Values For Physical Fitness
An observational study of Healthy Adults, run by Riphah International University at 1 site in Pakistan.
Trial summary
Physical fitness is a critical determinant of functional independence, disease prevention, and overall health. While global normative values for various fitness parameters exist, cultural, demographic, and ethnic differences necessitate the development of localized reference standards.

About this study
Official title: Normative Values For Physical Fitness Among Healthy Adults
Physical fitness is a critical determinant of functional independence, disease prevention, and overall health. While global normative values for various fitness parameters exist, cultural, demographic, and ethnic differences necessitate the development of localized reference standards. This study aims to establish normative values for key fitness indicators-body composition, cardiorespiratory endurance, muscular strength and flexibility.
It will be a descriptive cross-sectional study with approximately 800 participants through non-probability convenience sampling at Community Centers, Lahore. Fitness assessment will include body composition (height, weight, BMI, waist-hip ratio, skinfold, body fat analyzer), muscle strength (handgrip via dynamometer, quadriceps strength via sit-to-stand test), flexibility (sitand-reach test), and endurance (push-up, curl-up, and 3-minute step tests). The expected outcomes will provide valuable normative data to support clinicians, therapists, and researchers in evaluating and promoting physical health in adult populations.

Physical fitness is a critical determinant of functional independence, disease prevention, and overall health. While global normative values for various fitness parameters exist, cultural, demographic, and ethnic differences necessitate the development of localized reference standards. Pakistan lacks comprehensive normative data for physical fitness parameters in adults, making clinical assessment and health promotion strategies less precise. This study aims to establish normative values for key fitness indicators-body composition, cardiorespiratory endurance, muscular strength and flexibility.
It will be a descriptive cross-sectional study with approximately 800 participants through non-probability convenience sampling at Community Centers, Lahore. Participants will be screened for inclusion using the PAR-Q questionnaire. Fitness assessment will include body composition (height, weight, BMI, waist-hip ratio, skinfold, body fat analyzer), muscle strength (handgrip via dynamometer, quadriceps strength via sit-to-stand test), flexibility (sitand-reach test), and endurance (push-up, curl-up, and 3-minute step tests). The study ensures standardized protocols per American College of Sports Medicine guidelines and ethical approval from the institutional board. The expected outcomes will provide valuable normative data to support clinicians, therapists, and researchers in evaluating and promoting physical health in adult populations. These findings may enhance physical activity promotion, musculoskeletal health evaluations, and public health policymaking in Pakistan.

What is being measured
The primary outcome is the main question the study is designed to answer.
Sit-Up/Curl-Up Test
Muscular endurance: Sit-Up/Curl-Up Test is administered to evaluate of the abdominal and hip flexor muscles participants will lie in a supine position on a mat with knees bent at approximately 90 degrees and arms crossed over the chest (or hands reaching toward the knees for curl-ups). On the "go" signal, participants will perform as many controlled repetitions as possible within one minute, ensuring proper form and full range of motion in each repetition. The total number of correctly completed repetitions is recorded and compared to age- and gender-specific normative values
Measured: Baseline
Queen's college step test
Cardiorespiratory fitness: will be assessed by the Queen's college step test (reliability = 0.92, validity = 0.75) 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.
Measured: Baseline
body composition fat analyzer
Body composition will be measured by the body composition fat analyzer is a device that breaks down weight into its core components: fat, protein, minerals, and body water.
Measured: Baseline
skinfold caliper
Skinfold thickness will be assessed at five anatomical sites: Biceps, Triceps, calf, abdomen, and thigh using a standardized skinfold caliper to estimate body fat percentage through validated prediction equations such as the Jackson \& Pollock or Siri formula.
Measured: Baseline
handheld dynamometer
Muscular strength will be measured using a handheld dynamometer where participants will perform maximal isometric contractions with each hand three times, and the highest value from three trials will be recorded. For lower body strength, quadriceps strength will be assessed using a chair sit-tostand test
Measured: Baseline
Sit-and-Reach Test
Flexibility will be assessed by the Sit-and-Reach Test will be performed. Participants will sit on the floor with legs fully extended and feet placed flat against a standard sit-and-reach box. With hands placed one over the other, they will reach forward along the measuring scale as far as possible while maintaining straight knees. The farthest point reached by the fingertips is measured in centimeters and recorded. Two or three trials may be taken, with the best score used for analysis. Higher scores indicate greater flexibility.
Measured: Baseline

Questions about this trial
What is this clinical trial studying?
An observational study of Healthy Adults, run by Riphah International University at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: enrolling by invitation, as of the sponsor's last update on 7 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sit-Up/Curl-Up Test (time frame: Baseline). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07574424, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 May 2026.
