Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental Loaded high intensity circuit training |
These participants will be familiarized to all the exercises. All exercises will have 3 sets, and the participants will be asked to perform as many repetitions as they can in 30s for each set. They will have 30 seconds to rest between sets (if they want more rest, we can let them more time but not exceed 60 seconds to limit the total amount of time for completing the exercise protocol) and 90 seconds to rest between exercises. Training sessions will occur twice per week with at least 24 hours between sessions. From the week 2-5 of the intervention, the participants will perform the exercises with an adjustable weight vest starting with 2.5% to finally reaching 10% of their body weight. |

Detailed Description
Only 25% of independent ambulatory children with spastic cerebral palsy (CP) meet the recommendations of time spent in physical activity (PA). Lack of PA during growing years is one of the root causes of obesity, diabetes, and hypertension. Children with CP are known to have poorer dynamic balance and weaker muscle strength than typically developing children, explaining their slower walking speeds, lower PA, and higher tripping and falling than typically developing children. These deficits markedly amplify in adolescence. Consequently, there is a critical need to mitigate deficits in muscle strength and dynamic balance in ambulatory adolescents with CP to increase PA. High intensity circuit training (HICT) vs progressive resistance training (PRT) improved PA to a greater degree in children with CP. Despite the use of HICT, PA in children with CP is still below the recommended level. Our new exercise protocol combines the principles of HICT and PRT in one training program to improve PA in adolescences with CP. The aim of this study is to test the feasibility and response of a new exercise protocol on improving physical activity in adolescents with cerebral palsy. In order to test the feasibility and response of the new exercise protocol, this study will have 3 groups of participants: 1) functionally loaded high intensity training exercise group, 2) a high intensity circuit training group, and 3) control group. For those two exercise groups, this study will include 4-week (weeks 2 - 5) exercise training program (including chair squat, side-step, split squat, heel raise, and jump). Children may/may not wear a weighted vest during exercising depend on their assigned group. For the non-exercise/control group, there is no intervention. Each group will have 2 sessions of baseline testing in week 1 and 1 session of post-testing in week 6. Coming for a single session of testing in week 9 is optional. The following tests will be assessed before and after the exercise training program for all the groups: Lower limb strength and power via jump tests, balance via four-square step test, lateral step-up test, timed up and go tests, and walking tests. Their muscle and tendon stiffness will be assessed via a handheld device. Free living PA will be assessed via waist-worn accelerometers and questionnaires. Testing will be performed at 5 time points: tests at the first week (baseline 1 and baseline 2), sixth week (post training), ninth week (the follow up) of the study.
