| APEX | Behavioral | Three phases: warm-up, high-intensity interval training (HIIT) phase, cool-down. A 10-minute warm-up included deep breathing meditation and dynamic joint mobility exercises. Then, a 40-minute strength and balance workout in HIIT format with five different high-intensity (HI) exercises interspersed with five different postural stability recovery exercises. The HI intervals focused on enhancing cardiovascular fitness, muscle strength, and motor performance. The recovery intervals incorporated balance and mobility exercises. The HI exercises lasted 30 seconds for the first three weeks and then increased to 45 seconds in the fourth week while the recovery exercises lasted 60 seconds throughout the entire intervention. The HIIT phase was repeated three times in the 40 minute block. Lastly, a 10-minute cooldown consisting of standing and seated exercises similar to the warm-up. |
| Measure | Description | Time Frame |
|---|---|---|
| Attendance Rate | The number of classes attended out of eight total classes. | 4 weeks during intervention |
| Heart Rate | Heart rate measured in beats per minute. | 4 weeks during intervention |
| Functional Reach Test Distance | The distance in inches of an individual's forward reach with one arm while maintaining a standing position with feet flat on the floor at hip width. | Once 3-7 days before start of intervention and once 0-2 days after end of intervention |
| Timed Up-And-Go Time | The number of seconds for an individual to rise from a seated position, walk eight feet, turn around, and return to a seated position. | Once 3-7 days before start of intervention and once 0-2 days after end of intervention |
| Number of Steps in 2-minute Step Test | The number of right knee raises completed in two minutes while marching in place and raising each knee to a point midway between the patella (kneecap) and iliac crest (top hip bone). | Once 3-7 days before start of intervention and once 0-2 days after end of intervention |
| Number of Repetitions in 30-Second Chair Stand Test | The number of sit-to-stands completed in 30 seconds on a standard 17" seat-height chair with arms folded across the chest. | Once 3-7 days before start of intervention and once 0-2 days after end of intervention |
