Summary: The commonly used calcium desulfurizers have low efficiency, while NaHCO3 desulfurizers are expensive and difficult to handle. A new high-performance calcium desulfurizer was found, which has high desulfurization efficiency, wider applicable temperatures, and low preparation cost, showing significant potential for development in flue gas desulfurization.

Summary: This study aimed to describe the anthropometric differences and assess their correlation with physiological markers among road cyclists of different performance levels. The results showed that there were no significant anthropometric differences between trained, well trained, and professional cyclists, with only recreationally trained cyclists exhibiting larger perimeters and skinfolds than professional cyclists. Additionally, physiological performance did not distinguish between cyclists of different specialties, indicating restrained correlations with anthropometric values.

Summary: The study shows that a rowing-specific mindfulness intervention can improve athletes' flow, mindfulness, and performance, while reducing conscious motor processing. However, it does not have a preferential effect on mindfulness or reinvestment compared to the control group. Participants responded favorably to the intervention and evaluated it positively.

Summary: This study aimed to describe the effect of different altitudes on selected hematological, biochemical, and acid-base variables in adult horses. It was found that horses living at sea level had lower Htc, Hb, and PvCO2 compared to those living at altitudes >= 1000 masl. However, no differences were identified in total plasma protein and electrolyte concentrations.

Summary: The aim of this study was to assess the impact of technical and core stability parameters on rowing ergometer performance, defined as mean power at the handle. Analysis of 24 high-level rowers on an instrumented RowPerfect 3 ergometer revealed that leg, trunk, and arm power output significantly predicted mean power at the handle, with trunk power being the strongest predictor. Technical parameters such as time to peak power, work ratio, and mean to peak power ratio also played a role in predicting power output. Additionally, a greater trunk range of motion significantly influenced the power produced by this segment. These findings highlight the importance of technical training on dynamic ergometers to improve power output in rowers, with a focus on achieving earlier peak power, enhanced work production at the trunk and arm levels, and distributing power throughout the drive phase. Furthermore, the trunk plays a significant role as a power producer within the kinetic chain from the legs to the arms.

Summary: This paper presents the results of time-resolved flow field measurements around a realistic rowing oar blade moving through water, along with measurements of hydrodynamic forces acting on the blade. Analysis of the flow field during the drive phase revealed the relationship between leading-edge and trailing-edge vortices and the generation of instationary lift and drag forces for rowing propulsion. Adjusting the angle of the blade attachment improved the alignment of the generated impulse with the propulsive direction, increasing efficiency.

Summary: This review investigates the prevalence of cardiometabolic health risk factors among airline pilots. The analysis found that overweight and obesity, insufficient physical activity, elevated fatigue, and regular alcohol intake are major health risks for airline pilots. However, the quality and quantity of the current literature limit the strength of conclusions that can be drawn.

Summary: Digital self-tracking devices are becoming increasingly popular in everyday life, but many people abandon them shortly after acquisition. This article explores what happens when people unplug from these devices, considering the lingering effects of digital data on habitual practices. It argues that self-tracking prompts new embodiments that continue to unfold even after disengagement, challenging the idea that self-tracking simply stops in its absence.

Summary: There is a need for enhanced preventive health care among airline pilots, and a smartphone-based app intervention has been shown to be effective in improving health behaviors and cardiometabolic health parameters. In a randomized trial, 186 airline pilots participated in a personalized 16-week app intervention, resulting in significant positive health changes in objective health, subjective health, and health behaviors. This study highlights the potential of app-based interventions to improve cardiometabolic health among airline pilots.

Summary: The effectiveness and retention of a passive heat acclimation protocol integrated into a female Olympic rugby sevens team training program were investigated. The results showed that passive heat acclimation can improve thermoregulation and performance to some extent, but the thermoregulatory adaptations cannot be retained after 15 days without further heat stimulus.

Summary: This study conducted a systematic review and meta-analysis to evaluate the effect of daytime napping following normal night-time sleep on physical performance in physically active individuals and athletes. The findings indicated that napping after normal sleep improved performance in the 5-m shuttle run test, but had no significant effect on muscle force. Limited evidence was available for other physical performance measures.

Summary: This article reviews the various recovery devices and technologies that have emerged in the sport and athletic performance industry in recent years and categorizes them based on the strength of scientific evidence. The article states that foam rolling, compression garments, cryotherapy, photobiomodulation, hydrotherapy, and active recovery have a high level of positive evidence for improved recovery outcomes, while sauna, recovery boots/sleeves, occlusion cuffs, and massage guns have a lower level of evidence and inconsistent results. Finally, the article provides guidance for practitioners in selecting recovery strategies for athletes during different phases of the season.
