Hur påverkar högintensiv konditionsträning inflammationsparametrar hos individer med inflammatorisk ryggsjukdom - en pilotstudie
Abstract [sv]
Studien syftar till att få en bättre förståelse för och kartlägga akuta fysiologiska effekter av träning avseende inflammationsparametrar hos individer med axial spondylartrit (SpA). I en pilotstudie med tvärsnittsdesign kommer individer med SpA, som har olika träningsstatus, studeras för att avgöra om det är skillnader avseende de fysiologiska parametrar associerade med inflammation som anses kunna påverkas av högintensiv konditionsträning.

Abstract [en]

Background: Physical exercise is an important treatment for individuals with axial spondyloarthritis (axSpA). Although high-intensity training (HIT) has been shown to reduce disease symptoms and risk of comorbidity without exacerbating disease activity (1), compliance tends to decrease over time. Increased knowledge is needed on how to optimize and tailor individual exercise programs for continued regular exercising and improved health.

Objective: To study the effects of HIT on aerobic capacity, body composition, disease activity, physical function, health status and fatigue in individuals with axSpA after a 12-week intervention supported by digital coaching.

Methods: Twenty-two individuals (women, n=12), recruited from two rheumatology clinics in southern Sweden, were randomized to a HIT intervention group (HG; n=11) or a control group (CG; n=11). The HG completed three HIT sessions/week, including two interval training sessions (4x4 min), in self-selected activities for 12 weeks. The individuals in the HG were individually coached and had regular support from a physical therapist primarily by digital coaching. The CG continued exercising as usual. Assessment of aerobic capacity (VO2max), body composition (BMI and visceral fat area [cm2]), disease activity (CRP [µg/ml], BASDAI, 0-10 best-worst), physical function (BASFI, 0-10 best-worst), health status (EQ5D, 0-1 worst-best, ASAS health index [ASAS-HI], 0-17 best-worst), and fatigue (fatigue severity scale [FFS], 0-7 best-worst) were sampled at baseline and after 12 weeks. Mean and standard deviation (SD) were used for descriptive statistics. Repeated measures analysis of variance (ANOVA) was used to investigate effect of group (HG*CG) and time (PRE*POST), with a post-hoc analysis using t-tests when ANOVA indicated a significant difference in main effects or interactions. A significance level of p≤0.05 was used. Fisher´s exact test was used to study the effects over time for CRP (as dichotomized variable, > or < 4 µg/ml).

Results: Results presented are part of an ongoing RCT based on 19 individuals (women n=11) that have completed the 12-week follow-up analyses. The participants mean (SD) age was 48 (10) years, BMI 25 (4), VO2max 37 (6) mlO2/kg/min, and BASDAI 2.6 (0.3). No differences were present between the HG (n=9) and the CG group (n=10) at baseline for the studied variables. After 12 weeks of HIT an ANOVA interaction (p<0.05 showed that HG increased their VO2max (6.4 [3.6] mlO2/kg/min; p<0.001) but CG did not. For BMI, visceral fat area, disease activity (BASDAI), physical function (BASFI), fatigue (FFS) no differences in main effects or interactions were found (p>0.05). Health status (EQ5D) showed an ANOVA time main effect (p=0.007) where the HG increased their health status (0.10 [0.06] units; p=0.02) after 12-weeks, but CG did not. For health status measured with ASAS-HI no differences between groups were found. For dichotomized CRP-values no differences were found in either of the group’s pre-post. 

Conclusions: This pilot RCT shows that after 12 weeks of digital-based HIT intervention, the HG increased their aerobic capacity and EQ5D health status compared to CG, while body composition, disease activity, physical function, and fatigue did not show any significant differences between the groups.

Abstract [en]

Background: Physical exercise is included in the recommended treatment for individuals with axSpA, and different forms of aerobic training are known to improve health and cardiorespiratory function. However, little is known about the experiences of digital-based HIIT in individuals with axSpA.

Objective: To describe experiences of a digital-based HIIT intervention in individuals with axSpA.

Method: The participants completed a standardized training protocol, including three sessions/week (two HIIT sessions) in self-selected activities for 12 weeks. They used a fitness watch and were individually coached by a physical therapist primarily by telephone. Individual interviews were conducted with 12 participants (table 1). Open-ended questions were used such as; “How have you experienced the HIIT intervention?”, and “How has the HIIT intervention affected you?”. Data were analyzed by qualitative content analysis.

Results: The analysis resulted in four categories constituted of 12 subcategories (table 2) describing participation in a digital-based HIIT intervention as: 1) The intervention design creates opportunities for exercise through easy accessibility, time efficiency, and increased selfawareness.

Conclusion: Individuals with axSpA found that the intervention provided exercise opportunities. Encouragement and positive well-being effects was highlighted, but the need to overcome difficulties was also emphasized. These findings are key for implementing sustainable, individualized HIIT-based rehabilitation.
