Final answer:
The ACSM recommends push-up tests to assess upper-body endurance. These tests measure the capabilities of the pectoral muscles, triceps, and shoulder stability. For the provided pull-up power calculation, body weight, distance, and time are used to determine power output, while the rebound response is a neurological test for involuntary movements.
Step-by-step explanation:
The American College of Sports Medicine (ACSM) recommends the use of push-up tests to assess upper-body endurance. This method is an effective way to evaluate the endurance of the pectoral muscles and triceps, as well as the stability of the shoulder girdle. During a push-up test, the individual performs as many push-ups as they can without rest, maintaining proper form throughout. The test can be adapted for different fitness levels by altering the push-up style, such as doing the exercise on the knees for beginners.
To calculate the power output in the Pull-Up Power example provided, the trainee's body weight and the time taken to perform the pull-up are used. Assuming the distance covered in the pull-up is about 0.7 meters, we first calculate the work done against gravity which is the product of body weight (converted to Newtons), the vertical distance, and then divide by the time to find the power. For an 80-kg person, the force due to gravity is approximately 784 Newtons (80 kg × 9.8 m/s2). Therefore, the work would be 784 N × 0.7 m, and the power output is calculated by dividing this value by 0.8 seconds.
For neurological assessments like checking for tremors and the rebound response, this is usually performed by an examiner who looks for involuntary movements when the arms are extended and pressed down. The subtests that measure this are assessing the coordination provided by the lateral regions of the cerebellum.
