However, therapy effect sizes remain low. In other chronic disorders, training at higher intensity has resulted in greater improvements on both general health related and disease specific outcomes compared to lower intensity ET. Possibly, high intensity training also improves effect sizes in CNSLBP. Objective: To compare the effects of a high intensity ET program with a similar moderate intensity ET program on disability, pain, function, exercise capacity, and abdominal/back muscle strength in persons with CNSLBP. Methods: In a randomized controlled trial, persons with CNSLBP performed a 12-week ET program (24 sessions, 1.5hours/session, 2x/week) at high (HIT) or moderate intensity (MIT). Questionnaires to assess disability (Modified Oswestry Index (MODI)), pain intensity (Numeric Pain Rating Scale (NPRS)), and function (Patient Specific Functioning Scale (PSFS)), a cardiopulmonary exercise test to assess exercise capacity (VO2max, cycling time), and a maximum isometric muscle strength test to assess abdominal/back muscle strength (maximum muscle torque) were administered at baseline and after the training program. Results: Thirty-eight participants (HIT: n=19, MIT: n=19) were included (mean age: 44.1y, SD=9.8, 12 males). Groups did not differ at baseline. Between group differences (p<0.01) in favor of HIT were found for MODI, VO2max, and cycling time. Within group improvements (p<0.01) were found in both groups on MODI (HIT:-64%, MIT:-33%), NPRS (HIT:-56%, MIT:-39%), PSFS (HIT:+37%, MIT:+39%), VO2max (HIT:+14, MIT:+4%), cycling time (HIT:+18%, MIT:+13%), and back muscle strength (HIT:+10%, MIT:+14%). Conclusion: HIT proved to be a feasible, well tolerated, and effective therapy modality in CNSLBP. Moreover, it shows greater improvements on disability and exercise capacity than a similar ET performed at moderate intensity. | Keywords: | Chronic Low Back Pain;Exercise Therapy;High-Intensity Training;Rehabilitation;Randomized Controlled Trial | Document URI: | http://hdl.handle.net/1942/28906 | ISSN: | 0195-9131 | e-ISSN: | 1530-0315 | DOI: | 10.1249/MSS.0000000000002078 | ISI #: | WOS:000497515100002 | Rights: | 2019 American College of Sports Medicine | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2020 |
