Functional Anaerobic and Strength Training in Young Adults with Cerebral Palsy

Purpose To investigate the efficacy of a 12-week combined functional anaerobic and strength training program on neuromuscular properties and functional capacity in young adults with spastic-type CP. Methods 17 young adults (21±4 years, 9 males, GMFCS I=11, II=6) were randomized to 12 weeks, 3 sessions per week, of high intensity functional anaerobic and progressive resistance training of the lower limbs (n=8), or a waitlist control group (n=9). Pre- and post-training plantar flexor and tibialis anterior muscle volumes and composition, passive and active plantar flexor muscle properties, and functional capacity outcomes were assessed. Results The training group had higher values compared to the control group (adjusted mean difference) at 12-weeks for: more- and less-impaired total plantar flexor and tibialis anterior muscle volumes; maximum isometric plantar flexion strength; muscle power sprint test peak power; agility shuttle time; composite functional strength score; and six-minute walk test distance. The change in total plantar flexor muscle volume was associated with the change in plantar flexor muscle strength. There were relationships between the change in plantar flexor muscle strength and change in functional capacity outcomes (functional strength; six-minute walk test). Conclusions Combined functional anaerobic and strength training increased muscle size, strength and functional capacity in young adults with CP. The addition of anaerobic training to progressive resistance training programs assists in the transfer to improved functional capacity.
