SUSPENSION TRAINING EFFECTS ON LOW BACK PAIN AND FUNCTIONAL PEAK POWER FOLLOWING AN 8-WEEK TRAINING PROTOCOL

Abstract

PURPOSE: The purpose of this randomized exploratory study was to evaluate an 8-week strength training program using a fully off the ground suspension training apparatus in adults with LBP and its implication on 1) reducing LBP and 2) increasing functional sit-to-stand peak power (FSSPP) and quantifying changes following an 8-week training protocol when comparing the experimental (EXP) group (n = 4; 45.5±10.38 yrs) to the controlled (CON) group (n = 6; 45.5±14.02 yrs). METHODS: Ten male and female adults (BMI = 27.2±4.22; Ages 45.5±12.05 yrs) with LBP and pain intensity equal to or less than 40% in the Oswestry Low Back Pain Disability Questionnaire (OLBPQ) were qualified for inclusion in the study and were recruited from Murfreesboro, TN to participate in an 8-week strength training program (three visits/week, one hour/visit) exercising while suspended. The OLBPQ perceived pain scales was used to measure changes in back pain intensity; while the Tendo-Unit system was used to measure FSSPP across pre and post 8-week strength training program. Baseline difference between the two groups on the outcome variables were assessed using ANCOVA. All statistical significance was established at alpha level of p < 0.05. RESULTS: Mean values were: OLBPQ pre-training (EXP17.00±10.39 %; CON 4.33±5.85 %), post-training (EXP 4.00±4.89 %; CON 9.00±10.41 %); while FSSPP pre-training (EXP 1323±410 Watts; CON 1498±387 Watts), post-training (EXP 1694±649 Watts; CON 1375±326 Watts). Significant decrease in LBP F(1,8) = 11.86, p = .009, η2 = 0.59, power = 0.85; and a significant increase in FSSPP F(1,7) = 6.37, p = .04, η2 = 0.48, power = 0.80 were related to the 8-week training protocol using the exercise suspension device. CONCLUSION: The eight-week strength training protocol showed a statistically significant difference in reducing LBP and increasing FSSPP in the EXP group when compared to the CON group. Benefits for evaluating this new fitness machine in this trial would enhance our understanding to its impact as an alternative modality on reducing LBP and improving overall health and wellbeing. This work could be an extension to potential research studies to explore in therapy, rehabilitation and fitness industries (e.g. its effect on sports specific skills, autism, ADHD and PTSD).
