Discussion Questions: Why is it important to choose the appropriate type of assessment technique? Choosing the appropriate assessment technique for muscular endurance and strength testing is important in terms of what muscle you are trying to test to ensure you accurately obtain the strengths and weaknesses of that person. From there you can establish the proper ways to improve the strength or endurance of the muscle. Describe isokinetic strength and endurance training and the type of equipment it requires Isokinetic strength What is the level of strength and endurance of the participants on whom you have collected data? Do these participants need to improve in any areas? The level of strength and endurance of the participants varied throughout the participants What are the benefits and drawbacks of the grip dynamometer test? Advantages: Minimal equipment is required as only the grip is needed and it is relatively easy to set up and conduct as well as it is small and can be done almost everywhere, both sitting and standing. The test is quick, can be done in about 30 seconds Disadvantages: It is considered special equipment and is not found everywhere. Some need to be adjusted for hand size and this can be done inaccurately. The reading on the meter has to be done at while the person is completing the test and once they let go the hand on the meter will go back down to 0. Need someone to read the meter typically since the person taking the test generally has a hard time keeping it still and reading it while exerting maximum strength. Why do fitness professionals often examine abdominal endurance? Fitness professionals often examine abdominal endurance as the abdominal muscles are used throughout may daily activities and exercises even when not intended to. The core is the foundation of many parts of the body and plays a crucial role in power transfer to the appendicular skeleton. Therefore, the abdominal area is a good indicator of overall body endurance/ strength. Summarize the six flexibility tests done in this lab. Can they be used to evaluate overall flexibility? As stated in the methods, there were 6 tests that were completed by all the participants in this lab. They tested flexibility in the ankle, front chest and shoulders, abdominal region, lower back, hip flexors and extensors. With this being said all of these tests can be used to evaluate overall flexibility of a person as they cover all the majour areas of the body. How is flexibility or lack of flexibility related to lower back pain? The strength and flexibility of the abdominal muscles plays a key role in preventing the pelvis from tilting forward and from supporting the trunk to prevent bad posture all which lead to

lower back pain. Therefore, the more flexible and strong the abdominal areas is the less chance a person has of experiencing lower back pain What could you do to improve flexibility or your clients? First one must establish what areas of the body need improved flexibility by administering the tests started preiosuly in the methods and then Limitations:  In the study there were few people who were of sedentary activity level and were removed as they could be considered outliers  Some tests are measured by hand (with a ruler) and have more of a chance of human error opposed to tests that are measured electronically  Since the lab was done in class and not at the gym, most of the participants did not complete the leg press and bench press test  For more accurate results more sedentary participants are required.
