“…Therefore, the HFFS allowed participants to exercise at 60% HRR intensities while maintaining PPA below jogging and running values. This observation might 11 be particularly important for clinical populations that benefit from moderate-to high-intensity exercise but cannot tolerate high tibia PPA, such as osteoarthritis (22) (23) (24) or older adults (25)(26), or that typically report higher tibia PPA and ground reaction forces compared to their healthy matched participants (3)(9).…”

The ability to meet high exercise intensities is limited by the increased risk of injury in some clinical populations. Previous studies have linked large tibia peak positive accelerations resulting from running to increased risk of developing lower-extremity injury. The purpose of this study is to determine the feasibility of using a hip flexion feedback system (HFFS) to meet and maintain different exercise intensities while maintaining low tibia axial accelerations. Ten healthy participants were tested on a HFFS test and an independent walking/running test to meet exercise intensities of 40% and 60% of heart rate reserve (HRR). During the HFFS test, the HFFS controlled in real time the exercise intensity by directing individuals to specific maximum hip flexion targets during walking and providing visual information that assists them in maintaining low tibia peak positive accelerations during the initial contact phase. Maximum hip flexion targets during walking are calculated based on real-time readings of the participant’s heart rate. During the independent test, exercise intensity was controlled independently by the participant using treadmill speed. Compared to the independent test, using the HFFS at 60% HRR resulted in similar heart-rate error but lower tibia peak positive accelerations. No differences were observed for the 40% HRR intensity. This paper describes a novel exercise approach that uses the individual’s heart rate to calculate maximal hip flexion targets that an individual should meet during treadmill walking. The HFFS also provides tibia peak positive peak acceleration cues. Therefore, the HFFS can increase and control exercise intensities while maintaining low tibia accelerations. In particular, the HFFS might be an alternative strategy to meet moderate to vigorous exercise intensities in populations at risk of developing lower-extremity injuries.

Studies have shown that individuals with knee osteoarthritis (KOA) may benefit from cycling exercise. However, the supportive evidence remains unclear. This systematic review aimed to investigate the effects of cycling rehabilitation training (CRT) on the recovery of osteoarthritic knee joints. Five databases were searched with publishing date restrictions from 1 January 2000 to 1 March 2022. We included studies that 1) recruited participants with KOA, 2) used CRT in the intervention, 3) compared measurements before and after the intervention or between a KOA group and a healthy group, and 4) included the measurements of interest. The quality of the studies was assessed using the modified Downs and Black checklist. A random-effects meta-analysis of Western Ontario and McMaster Universities Arthritis index, Lequesne index, and Timed Up and Go test scores was performed. The changes in muscle strength, kinetics, and kinematics as a result of the intervention were summarised. The quality of the 19 included studies was moderate with a median quality score of 19.05. CRT improved muscle strength and physical function (SMD 0.94, 95% CI [0.66, 1.22]), and reduce pain (SMD 0.94, 95% CI [0.66, 1.22]) and joint stiffness (SMD 0.74, 95% CI [0.46, 1.01]) in KOA patients. Compared with healthy subjects, KOA patients showed increased extensor moments and abduction peak adduction angles of their knee joints, and decreased internal rotation moment and peak angles of knee flexion and extension. CRT was effective in relieving knee pain, restoring motor function, and improving lower limb muscle strength. Knee abduction moment may be an indicator of rehabilitation progress.

Physical activity, physical fitness and cardiometabolic risk amongst adults with moderate and severe haemophilia

et al. 2022

Aim: This study aimed to examine physical activity (PA), physical fitness and cardiometabolic risk amongst people with moderate and severe haemophilia (PwMSH). Methods:The following domains were examined: PA (accelerometry); functional aerobic capacity (6-Minute Walk Test); grip strength (dynamometry); balance (One Leg Stand Test); body composition (anthropometry and bioimpedance analysis); blood pressure; arterial stiffness; and cardiometabolic disorders.Results: A total of 53 PwMSH (44 years) and 33 controls (43 years; p = .679) were recruited. Compared to controls, PwMSH were significantly less active in moderate and vigorous PA parameters (all p < .05), and less physically fit indicated by 6-Minute Walk distance (p < .0005), grip strength (p = .040) and balance (p < .0005). PwMSH had higher rates of abdominal adiposity compared to controls measured by waist circumference indices (all p < .05). Resting blood pressure and arterial stiffness were not significantly different (p = .797 and .818, respectively). With respect to overall PA, World Health Organisation recommended targets for adults were achieved by the majority of both groups (haemophilia: 72.9% vs. controls: 90.0%; p = .069). Importantly, the number of PwMSH who achieved guideline recommended PA via longer, sustained bouts of moderate-vigorous PA was significantly lower compared to controls (18.8% vs. 56.7%; p = .001). Lastly, clinically diagnosed hypertension, insulin resistance and hyperlipidaemia were more prevalent amongst PwMSH compared to controls. Conclusion:Low levels of PA and physical fitness, and significant rates of abdominal adiposity and hypertension may collectively influence the risk and severity of various cardiometabolic and/or musculoskeletal health issues amongst ageing PwMSH.Personalised multi-disciplinary health interventions involving PA, dietary and health psychology input for PwMSH warrant future investigation.
