| Measure | Time frame |
|---|---|
| Primary fitness measures, all measured at both pre- and post-intervention (12 weeks): R/L means an average of both the Right and Left side of the body 1. Abdominal circumference (inches), measured using a tape measure 2. Sled Push & Pull R/L (seconds) measured by pushing (15 yds) and pulling (15 yds) a 140 lb sled twice 3. Rotation Smash Ball R/L (inches), measured distance thrown of a heavy medicine ball 4. Weight (pounds), measured with a scale 5. Wingate Upper Body (Watts/kg) measured using an arm crank with fixed resistance for 30 seconds 6. Body fat (% body weight) measured using DEXA overall and segmented body composition 7. Modified Illinois Agility (seconds) measured by quickly completing a weaving running course 8. Pull-ups (1 minute to complete as many as possible) 9. Push-ups (1 minute to complete as many as possible) 10. Sit-ups (1 minute to complete as many as possible) 11. Standing long jump (inches), best of three jumps from a 2-foot static position 12. VO2 Max (mL/kg/min), oxygen consumption measured on treadmill 13. Wingate Lower Body (Watts/kg), bicycle pedal with fixed resistance for 30 seconds 14. Lateral Bridge R/L (seconds), isometric hold for 30 seconds 15. Lower Y Balance Test R/L (seconds), multi-planar movement to test lower body balance 16. Supine Bridge R/L (seconds), isometric hold until exhaustion 17. Upper Y Balance Test R/L (seconds), multi-planar movement to test upper body balance 18. Diastolic blood pressure (mmHg), average of three readings taken at rest 19. Systolic blood pressure (mmHg), average of three readings taken at rest 20. Maximum heart rate (beats/minute), measured with electronic monitor 21. Resting heart rate (beats/minute, measured with electronic monitor 22. Lean muscle mass (pounds), measured with DEXA overall and segmented body composition Primary cognitive measures, all measured at both pre- and post-intervention (12 weeks): 1.
