摘要
Purpose: This study sought to find out if a 6-week accommodating variable-resistance (AcVR) training might enhance muscle architecture, peak torque, and functional performance in patients with juvenile idiopathic arthritis (Juv-IA). Methods: Fifty-eight patients with polyarticular Juv-IA (aged 12-18 years) were involved in a randomized controlled trial. They were allocated into two groups: the AcVR group (n = 29; underwent AcVR training, and the control group (n = 29; received the usual exercise regimen). Interventions were applied three times a week over six consecutive weeks. Measurements were done at baseline and after the intervention. The primary outcome measures were muscle architecture and peak torque, with functional capacity being the secondary measure. Results: Compared to the control group, the AcVR group showed favorable pre-to-post changes in muscle architecture [fascicle length (P = 0.0007, eta 2p = .18), pennation angle (P = 0.0004, eta 2p = .20), and muscle thickness (P = 0.001, eta 2p = .17)]. Further, the AcVR group revealed a greater increase in peak concentric torque of knee extensors at angular speeds of 120 degrees/sec [right side (P = 0.0032, eta 2p = .08); left side (P = 0.039, eta 2p = .07)] and 180 degrees/sec [right side (P = 0.01, eta 2p = .11); left side (P = 0.014, eta 2p = .10)]. Furthermore, The AcVR group achieved more conducive changes in functional performance [6-min walk test (P = 0.003, eta 2p = .15), timed up and down stair test (P = 0.009, eta 2p = .12), and 4 x 10 m shuttle run test (P = 0.036, eta 2p = .08)]. Conclusion: A 6-week AcVR training is potentially effective for improving muscle architectural qualities, enhancing peak muscle torque, and boosting functional performance in patients with Juv-IA without experiencing any detrimental side effects.
