Summary: This study aimed to investigate the effect of isolated dehydration on cardiopulmonary exercise capacity. The results showed that dehydration caused a reduction in body water and an increase in urine osmolality, and led to decreased oxygen uptake, minute ventilation, and power output. The conclusion is that isolated dehydration impairs workload and peak oxygen uptake in recreational athletes, suggesting an important role of dehydration in the heat-induced reduction of exercise capacity.

Summary: The study provided normative reference values for aerobic capacity in apparently healthy Greek subjects for the first time using CPET with a cycle ergometer. Male subjects achieved significantly higher levels of VO2max compared to females across all ages, and a decline in VO2max was observed in older participants of both sexes. Greek subjects had lower AC than North Europe cohort and were almost similar to the USA cohort, emphasizing the need for individual countries to develop their own AC reference values.

Summary: This study evaluated whether exercise testing with the upper limbs can be used equivalently to that of the lower limbs in assessing exercise capacity. The results suggested that exercise capacity assessed by exercise testing with the upper limbs is underestimated, regardless of the training status of the upper limbs.

Summary: The protein irisin is involved in adipose tissue browning and metabolism regulation. Researchers recently discovered that the extracellular chaperone heat shock protein-90 (Hsp90) serves as the activating factor for the opening of the alpha V beta 5 integrin receptor, allowing for high-affinity irisin binding and effective signal transduction.

Summary: Irisin produced during exercise plays a crucial role in improving metabolism, preventing inflammation-related diseases, and potentially combating conditions like COVID-19.

Summary: This study found that exercise capacity is lower in late preterm children compared to term children, but within the normal range, and comparable to that of early preterm children, with and without bronchopulmonary dysplasia (BPD). Lung function is only lower than normal in early preterm children.

Summary: Cardiac rehabilitation after acute myocardial infarction in patients with preserved left ventricular ejection fraction can improve exercise capacity, particularly through increased heart rate response and improved peripheral oxygen extraction during exercise.

Summary: This study compared the effects of treadmill and bicycle ergometer exercise modes during CPET in CHD patients. The results showed a higher incidence of cardiovascular events in the treadmill group compared to the bicycle ergometer group, indicating that bicycle ergometer exercise may be a safer option.

Summary: The study found that individuals in the community-recovered group showed no significant differences in cardiopulmonary health compared to physically active healthy controls, indicating their readiness to return to higher levels of physical activity. However, the hospitalized-recovered group and individuals with persistent symptoms exhibited enduring functional limitations, pointing to the need for continued monitoring, rehabilitation, and recovery.

Summary: This study compared actual VO2 max and predicted VO2 max using exercise capacity equations in Korean subjects. The results suggest that prediction equations developed for Caucasians may not be appropriate for Koreans, and the Chinese equation might be a better option for the Korean adult population.

Summary: This study evaluated the clinical value of cardiopulmonary exercise testing (CPET) in amyotrophic lateral sclerosis (ALS). The results showed that ALS patients had significantly decreased exercise capacity, and the peak oxygen consumption (VO2 peak) and peak heart rate (HR peak) were closely correlated with disease severity and predicted a worse prognosis.

Summary: This study compared patients with severe refractory asthma (SRA) and healthy controls using cardiopulmonary exercise testing (CPET), finding no significant difference in peak oxygen uptake between the two groups. Among the patients, isolated exercise-induced bronchoconstriction (EIB) was present in 30%, isolated physical deconditioning in 25%, physical deconditioning accompanied by EIB in 25%, and exercise-induced symptoms not supported by CPET data in 15%.

Summary: The aim of this pilot study is to evaluate physical fitness and its correlation with functional dyspnea in COVID-19 survivors 6 months post-discharge. Results show that persistent dyspnea is associated with reduced physical fitness, with differences between ICU and general ward patients. Tailored rehabilitation interventions may be beneficial for those with persistent dyspnea.

Summary: This study assessed the cardiorespiratory fitness and strength levels of women with and without polycystic ovary syndrome (PCOS), matched for age, body composition, androgenic pattern, and insulinemic pattern. The results showed that women with PCOS had better cardiorespiratory fitness, strength levels, and exercise capacity compared to the control group. These findings suggest that PCOS itself does not limit exercise capacity and does not exclude good functional capacity.

Summary: Exercise training is beneficial for physical and bone health, and the hormone irisin plays a key role in regulating bone metabolism through mechanical forces induced by exercise. Irisin may serve as a novel biomarker for bone metabolism and is influenced by various pathological conditions such as diabetes, obesity, and inflammation. Understanding the regulation of irisin and its impact on skeletal metabolism will be crucial for the treatment and prevention of bone diseases and chronic disorders.
