Summary: The study found that exercise intensity did not have an impact on asymmetry in pedaling forces during cycling, but it significantly affected the absolute and relative power outputs, as well as pedal force effectiveness with different participant groups.

Summary: Exercise with reduced muscle mass leads to greater muscle-specific adaptations compared to training with larger muscle mass. Single-leg cycling is an effective exercise that promotes positive physiological adaptations by confining the exercise to a smaller muscle mass and improving blood flow. Numerous studies have shown the cardiovascular and metabolic benefits of single-leg cycling for various populations.

Summary: Evidence suggests that respiratory frequency (fR) is sensitive to changes in exercise tolerance. This study compared arm+leg cycling (Arm+leg) and leg cycling (Leg) to further investigate this notion and found that Arm+leg had a greater exercise tolerance compared to Leg. Results also showed that minute ventilation, fR, and perceived exertion were sensitive indicators of exercise tolerance.

Summary: Health impact assessments (HIAs) have been used to evaluate the benefits and risks of cycling and other transportation interventions. A new HIA framework was developed to assess intra-city spatial variation and equity in the health tradeoffs of cycling. The framework was applied to Los Angeles, CA, and showed that promoting cycling could significantly reduce mortality risk, but the benefits were lower in communities with higher percentages of Black and Hispanic residents and lower socioeconomic status.

Summary: In high-altitude areas, using exercises with smaller muscle mass can offset the reduction in tissue oxygenation observed during activities with larger muscle mass, allowing athletes to exercise at higher limb/muscle specific intensities.

Summary: To combat drug-resistant bacteria, researchers developed copper-doped guanine-derived nanosheets that have the catalytic properties of glucose oxidase and peroxidase. These nanosheets produce free radicals when exposed to light, effectively eliminating drug-resistant bacteria. The nanosheets also promote the activation of oxygen and the splitting of hydrogen peroxide, causing damage to the bacterial cell membrane and an increase in reactive oxygen inside the cells. This study showed that the nanosheets efficiently eliminated Staphylococci in infected wounds and accelerated wound closure in a mouse model, with minimal side effects on normal tissues. These nanosheets could serve as a non-antibiotic alternative for treating bacterial infections.

Summary: This study aimed to investigate the impact of fast and slow pedaling speed on muscle damage during eccentric muscle actions (ECCs) cycling with equal mechanical work. The results showed that the magnitude of muscle damage is similar regardless of the pedaling speed when performing equal work.

Summary: A cyclist's performance depends on their average mechanical power output (AMPO), which is influenced by the instantaneous mechanical power output. Radial pedal forces do not contribute to mechanical power. However, it has been found that limiting radial pedal forces decreases the maximal AMPO from 1115W to 528W.

Summary: This article introduces a new single-legged lower-limb rehabilitation robot (S-LLRR) that is easy to move and suitable for different height carriers. The mechanical leg has a variable working space, and its rotating joints are designed with mechanical limiters. The series configuration of the S-LLRR was analyzed, trajectory planning was performed, and an active training control method based on the sand model was proposed. The simulation and experimental results showed that S-LLRR had a large workspace and good motion accuracy.
