“…The main power output was initially produced with the nonoperated leg, showing the presence of an inter-limb compensation strategy. In cycling, an inter-limb strategy has been shown for other injuries and selected time points [33,34], but not its successive reduction during the rehabilitation as in this case report. Beside the reduction of the inter-limb compensation strategy, the power output and the training duration was stepwise increased.…”

Background: A complete avulsion of the proximal rectus femoris muscle is a rare but severity injury. There is a lack of substantial information for its operative treatment and rehabilitation; in particular there is a lack of biomechanical data to evaluate long-term outcomes. Case presentation: The case report presents the injury mechanism and surgical treatment of a complete avulsion of the proximal rectus femoris muscle in a 41-year-old recreational endurance athlete. Moreover, within a one-year follow-up period, different biomechanical tests were performed to get more functional insights into changes in neuromuscular control, structural muscle characteristics, and endurance performance. Within the first month post-surgery, an almost total neuromuscular inhibition of the rectus femoris muscle was present. A stepwise reduction in inter-limb compensations was observable (e.g., in crank torque during cycling) during the rehabilitation. Muscular intra-limb compensations were shown at six months post-surgery and even one year after surgery, which were also represented in the long-term adaption of the muscle characteristics and leg volumes. A changed motor control strategy was shown by asymmetric muscle activation patterns during ergometer cycling, while the power output was almost symmetric. During rehabilitation, there might be a benefit to normalizing neuromuscular muscle activation in ergometer cycling using higher loads. Conclusions: While the endurance performance recovered after six months, asymmetries in neuromuscular control and structural muscle characteristics indicate the long-term presence of inter- and intra-limb compensation strategies.

“…Stationary cycling exercise may be beneficial for improving sport function, especially in the promotion of endurance and leg strength, 23,24 since cycling associated with long-term training has a positive effect on enhancing cardio-respiratory function and strengthening the lower extremity. 25,26 Such physical abilities, potentially improved by stationary cycling, are well-reflected in the sport sub-scale of the Knee Injury and Osteoarthritis Score, which is largely based on questionnaire items related to squatting, running, jumping, twisting, and kneeling.…”

Objective: To evaluate effects of stationary cycling exercise on pain, function and stiffness in individuals with knee osteoarthritis. Data sources: Systematic search conducted in seven databases (PubMed, Embase, Cochrane Library, Web of Science, EBSCO, PEDro, and CNKI) from inception to September 2020. Review methods: Included studies were randomized-controlled trials involving stationary cycling exercise conducted on individuals with knee osteoarthritis. End-trial weighted mean difference (WMD) and 95% confidence interval (CI) were analyzed, and random-effects models were used. Methodological quality and risk bias were assessed by using the Physiotherapy Evidence Database scale and Cochrane Collaboration tool, respectively. Results: Eleven studies with 724 participants were found, of which the final meta-analysis was performed with eight. Compared to a control (no exercise), stationary cycling exercise resulted in reduced pain (WMD 12.86, 95% CI 6.90–18.81) and improved sport performance (WMD 8.06, 95% CI 0.92–15.20); although most of the meta-analysis results were statistically significant, improvements in stiffness (WMD 11.47, 95% CI 4.69–18.25), function (WMD 8.28, 95% CI 2.44–14.11), symptoms (WMD 4.15, 95% CI −1.87 to 10.18), daily living (WMD 6.43, 95% CI 3.19 to 9.66) and quality of life (WMD 0.99, 95% CI −4.27 to 6.25) for individuals with knee osteoarthritis were not greater than the minimal clinically important difference values for each of these outcome measures. Conclusions: Stationary cycling exercise relieves pain and improves sport function in individuals with knee osteoarthritis, but may not be as clinically effective for improving stiffness, daily activity, and quality of life.

To examine the acute influence of pedaling cadence on arterial stiffness in young men, 15 healthy men (21.8±0.4 years) underwent 3 trials in self-control crossover design: non-cycling control (CON), cycling at 60 (RPM60) and 90 rounds per min (RPM90). Cycling lasted 30 min at intensity of 35% heart rate reserve. Arterial stiffness in cardio-ankle vascular index (CAVI) was measured at baseline (BL), immediately after (0 min) and 40 min after cycling. There were no significant CAVI changes over time in CON. CAVI in RPM60 decreased immediately after exercise and returned to baseline afterwards (6.1±0.2, 5.6±0.2 and 6.0±0.2 at BL, 0 and 40 min, respectively). RPM90 elicited significant CAVI reduction from 6.2±0.2 at BL to 5.5±0.2 at 0 min, and reverted to 5.7±0.1 at 40 min, maintaining significant difference to its baseline. There was no significant CAVI difference between RPM60 and CON, whereas CAVI in RPM90 was significantly lower than that in CON at 0 min (5.5±0.2 vs 6.1±0.2, P<0.01) and 40 min (5.7±0.1 vs 6.3±0.1, P<0.05). Despite equivalent exercise volume, arterial stiffness improvement induced by cycling was influenced by pedaling cadence. Higher cadence resulted in superior effect on arterial stiffness.
