Trunk Lift Explanation

Trunk Lift Example

Improve/Maintain Out of Class

Students can continue to practice good posture out of class as well as in class. Yoga can be done for 15 to 20 minutes of consecutive movement to also improve or maintain trunk extensor strength and flexibility at home. Practicng the superman will also benefit as a good practice of strengtheing. Using the abdominal muscles, hamstings, and back extensors to perform strecthes will benefit the lower back.

Improve/Maintain In Class

Students can improve or maintain good trunk extensors by practicing good posture when standing and sitting. We will also work to improve and maintain through daily strecthes performed before our daily lesson. Which includes,several yoga poses such as the cobra, cat/cow, and forward bend. Stretches will incorporate the abdominal muscles, hamstrings, and back extensors to maintain a healthy low back.

Class Performance

The classes performance as a whole shows that everyone in the class is in the healthy range for test 1 and 2 of the trunk lift. For test one, the males scored on average higher than the girls for both trial trunk lifts. The results from test one also reveal that lower scores were recorded for the class as whole for the first trial trunk lift. Females scored slightly lower than the males for test one. As a whole for test one, 5 students scored lower on first trial, 2 scored lower on second trial, 5 scored higher on the second trial, and 9 students scores reamined the same for trial 1 and 2. The male average for trial 1: 11.83 inches, trial 2: 11.83 in. Female average for trial 1:11 inches, trial 2: 11.6 in. Class average for trial 1: 11.31 inches, trial 2: 11.62in.

Test 2 the scores were higher as a whole because students were comfortable with the test and knew how to do it with correct form.

Control for Reliability

The trunk extensor test can be very realiable. The time between test administraion may effect the results slightly. Changes in the test takers body may also alter the results of the test. Students could alter the accuracy of the test results by not focusing on the chip placed infront of them and maintaing a neutral spine. To control the realiability the same equipment was used during both tests. The same directions were also recalled for both testing trials.

Test Validity

NASPE or National Associtaion for Sports and Physical Education recommends that the trunk lift be administered as part of the FITNESSGRAM. The FITNESSGRAM was designed by the Cooper Institute and is reconized by NASPE as a valid test. The FITNESGRAM will assist in acccomplishing the primary objective of youth fitness programs, which is to help students establish physical activity as a part of their daily lives.
