Objective
To study the efficacy of aquatic resistance training on biochemical composition of tibiofemoral cartilage in postmenopausal women with mild knee osteoarthritis (OA).
Design
Eighty seven volunteer postmenopausal women, aged 60–68 years, with mild knee OA (Kellgren–Lawrence grades I/II and knee pain) were recruited and randomly assigned to an intervention (n = 43) and control (n = 44) group. The intervention group participated in 48 supervised aquatic resistance training sessions over 16 weeks while the control group maintained usual level of physical activity. The biochemical composition of the medial and lateral tibiofemoral cartilage was estimated using single-slice transverse relaxation time (T2) mapping and delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC index). Secondary outcomes were cardiorespiratory fitness, isometric knee extension and flexion force and knee injury and OA outcome (KOOS) questionnaire.
Results
After 4-months aquatic training, there was a significant decrease in both T2 −1.2 ms (95% confidence interval (CI): −2.3 to −0.1, P = 0.021) and dGEMRIC index −23 ms (−43 to −3, P = 0.016) in the training group compared to controls in the full thickness posterior region of interest (ROI) of the medial femoral cartilage. Cardiorespiratory fitness significantly improved in the intervention group by 9.8% (P = 0.010).
Conclusions
Our results suggest that, in postmenopausal women with mild knee OA, the integrity of the collagen-interstitial water environment (T2) of the tibiofemoral cartilage may be responsive to low shear and compressive forces during aquatic resistance training. More research is required to understand the exact nature of acute responses in dGEMRIC index to this type of loading. Further, aquatic resistance training improves cardiorespiratory fitness.

Exercise for the intervertebral disc : a 6-month randomised controlled trial in chronic low back pain
Owen, Patrick J.; Miller, Clint T.; Rantalainen, Timo; Simson, Katherine J.; Connell, David; Hahne, Andrew J.; Trudel, Guy; Ford, Jon J.; Belavy, Daniel L. (Springer, 2020)Background context Muscle, bone and tendon respond anabolically to mechanical forces. Whether the intervertebral disc (IVD) can benefit from exercise is unclear. Purpose To examine whether exercise can beneficially ... -
