Conclusion Exercises and PA promotion according to public health recommendations  for PA improved cardiovascular fitness , muscle strength and PA behaviour , with moderate effect sizes in people with SpA , RA and HOA/KOA .
Objective To evaluate the effectiveness of exercise and physical activity ( PA ) promotion on cardiovascular fitness , muscle strength , flexibility , neuromotor performance ( eg , balance ) and daily PA in people with rheumatoid arthritis ( RA ) , spondyloarthritis ( SpA ) and hip/knee osteoarthritis ( HOA/KOA ) .
Is Home-Based, High-Intensity Interval Training Cycling Feasible and Safe for Patients With Knee Osteoarthritis?
Background : Osteoarthritis ( OA ) is a degenerative joint disease affecting the knee joint of many middle-aged and older adults . As OA symptoms typically involve knee pain and stiffness , individuals with knee OA are often insufficiently physically active , have low levels of physical function , and are at increased risk of other comorbidities and reduced quality of life . While moderate-intensity continuous training ( MICT ) cycling is often recommended , little is known about the feasibility , safety , and benefits of high-intensity interval training ( HIIT ) cycling for this population , even though the feasibility , safety , and benefits of HIIT have been demonstrated in other chronic disease groups . Purpose : The primary objective of this pilot study was to examine the feasibility and safety of home-based HIIT and MICT cycling in middle-aged and older adults with knee OA . A secondary objective was to gain some insight into the relative efficacy of HIIT and MICT for improving health status ( pain , stiffness , and disability ) , muscle function , and body composition in this population . This study protocol is being published separately to allow a detailed description of the research methods , explain the rationale for choosing the method ological details , and to stimulate consideration of the best means to simulate a research protocol that is relevant to a real-life treatment environment . Study Design : R and omized pilot study protocol . Methods : This trial sought to recruit 40 middle-aged and older adults with knee OA . Participants were r and omly allocated to either continuous ( MICT ) or HIIT home-based cycle training programs , with both programs requiring the performance of 4 cycling sessions ( approximately 25 minutes per session ) each week . Participants were measured at baseline and postintervention ( 8 weeks ) . Feasibility and safety were assessed by adherence rate , dropout rate , and number of adverse events . The relative efficacy of the cycling programs was investigated by 2 knee OA health status question naires ( Western Ontario and McMaster Universities Osteoarthritis Index scale[WOMAC ] and the Lequesne Index ) as well as the timed up and go , sit to st and , preferred gait speed , and body composition . Discussion : This pilot study appears to be the first study assessing the feasibility and safety of a home-based HIIT training program for middle-aged and older adults with knee OA . As HIIT has been demonstrated to be more effective than MICT for improving aspects of health status , body composition , and /or muscular function in other chronic disease groups , the current study has the potential to improve patient outcomes and inform the design of future r and omized controlled trials
