Progressive Resistance

Purpose:Exercise interventions have been shown to increase motor capacities in adolescents with cerebral palsy; however, how they affect habitual physical activity (HPA) and sedentary behavior is unclear. The main objective was to correlate changes in HPA with changes in mobility capacity following exercise interventions.Methods:A total of 54 participants (aged 12–20 y) with bilateral spastic cerebral palsy at Gross Motor Function Classification System (GMFCS) levels II and III received 4 months of group progressive resistance training or treadmill training. Mobility measurements and HPA (averaged over 96 h) were made before and after interventions.Results:Averaged baseline mobility and HPA measures and improvements in each after both interventions were positively correlated in all participants. Percentage of sedentary/awake time decreased 2%, with significant increases in HPA measures of step count (16%), walk time (14%), and upright time (9%). Mobility measures and HPA changes were quite similar between Gross Motor Function Classification System levels, but improvement in HPA after group progressive resistance training was greater than after treadmill training (12% vs 4%) and correlated with mobility improvement.Conclusions:Mobility capacity improved after these interventions and was clearly associated with improved HPA. The group progressive resistance training intervention seems preferable to improve HPA, perhaps related to greater social interaction and motivation provided by group training.

Purpose: The comparison of habitual physical activity and sedentary time in teenagers and young adults with cerebral palsy (CP) with typically developed (TD) peers can serve to quantify activity shortcomings. Methods: Patterns of sedentary, upright, standing, and walking components of habitual physical activity were compared in age-matched (16.8 y) groups of 54 youths with bilateral spastic CP (38 who walk with limitations and 16 who require mobility devices) and 41 TD youths in the Middle East. Activity and sedentary behavior were measured over 96 hours by activPAL3 physical activity monitors. Results: Participants with CP spent more time sedentary (8%) and sitting (37%) and less time standing (20%) and walking (40%) than TD (all Ps < .01). These trends were enhanced in the participants with CP requiring mobility devices. Shorter sedentary events (those <60-min duration) were similar for TD and CP groups, but CP had significantly more long sedentary events (>2 h) and significantly fewer upright events (taking <30, 30–60, and >60 min) and less total upright time than TD. Conclusion: Ambulant participants with CP, as well as TD youth must be encouraged to take more breaks from being sedentary and include more frequent and longer upright events.

Abstract Objective The aim of the study was to examine the variability in plantar-flexor muscle strength changes after progressive resistance training for adolescents with cerebral palsy (CP) and to identify baseline variables associated with change in muscle strength. Methods Thirty-three adolescents with CP were randomized to a 10-week progressive resistance training program as part of a randomized controlled trial (STAR trial). The associations between muscle strength at 10 weeks (n = 30 adolescents) and 22 weeks (n = 28 adolescents) and biomechanical and neuromuscular baseline characteristics, motor function, and fidelity to the program were examined with multivariable linear regression. Conclusion Assessing levels of muscle activation may be able to identify responders to a progressive resistance training program for adolescents with CP. These findings are a first step toward developing tools that can inform decision making in the clinical setting. Impact Due to the heterogenous nature of CP, it is challenging to assess the efficacy of strength training programs in individuals with CP and to understand the variability in outcomes among participants. This study provides a better understanding of the factors that predict response to an exercise program so that resistance training can be directed to those who will potentially benefit from it. Lay Summary There is wide variability in how well young people with CP respond to resistance training. If you are a young person with CP, your physical therapist can measure the amount of your gastrocnemius muscle activity to get an indication of how well you will respond.

Purpose: To observe the effects of progressive resistance training on performance and body composition in participants with cerebral palsy. Methods: Four quadriplegic (3 male, 1 female) and two hemiplegic (2 female) participants (22 ± 5 yr, mean ± SD) completed moderate to high intensity resistance training 2-3 days a week for 8-weeks. Strength training programs were developed for each participant based on their physical ability. Measurements of exercise performance and body composition (InBody 270 & S10) were collected prior to and following training. Data from all participants was pooled, and samples with 5-6 subjects were analyzed using a paired t-test with significance set at p < 0.05. Results: Measurements of muscular fitness improved, including plank performance (pre: 64 ± 40, post: 95 ± 61 s, n = 6), supine sled leg press 1RM (pre: 225 ± 69, post: 378 ± 124 lb, n = 6) and bench/sled press 1RM (pre: 92 ± 54, post: 115 ± 58 lb, n = 5). There was no change in peak sprint capacity (pre: 89 ± 32, post: 96 ± 29 W, n = 5) or peak aerobic capacity (pre: 303 ± 136, post: 370 ± 246 s, n = 4). Measurements of body weight (pre: 151 ± 40, post: 151 ± 42 lb, n = 6) and skeletal muscle mass (pre: 53 ± 8, post: 54 ± 9 lb, n = 6) were unchanged following training. Conclusion: Preliminary data is encouraging that the unique and challenging strength training program employed with these participants can be utilized to gain meaningful improvements in muscular fitness. However, a larger sample size and longer training period may be necessary to significantly increase muscle mass.
