Brief 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. 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.

Outcome Measures

Primary Outcomes (6)

• 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

  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.

  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.

  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.

  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

  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.
