Summary: The study demonstrates that prolonged exercise leads to a decrease in external work output at the moderate-to-heavy intensity transition due to decreased efficiency and rates of metabolic energy expenditure, while the associated heart rate increases.

Summary: This study compared the effects of running and cycling on neuromuscular function. The results showed that despite similar reductions in knee extensor strength after both types of exercise, the mechanisms responsible for force loss differed. Running exercise was associated with greater impairments in nervous system function, particularly at the spinal level, while cycling exercise resulted in greater impairments in contractile function. This may be due to differences in the mechanical and metabolic demands imposed on the quadriceps during these two forms of exercise.

Summary: This study investigates the effects of endurance stimuli intensity on the adaptation in strength and endurance following concurrent training, as well as the impact of training status on the acute molecular response to concurrent exercise. The results indicate that the intensity of endurance activity does not affect performance outcomes after concurrent training, and training status has no effect on the molecular responses assessed.

Summary: There is growing evidence that physical exercise may improve cognitive performance, although the specific criteria for exercise intensity, duration, and frequency are still being studied. This study investigated the effect of high-intensity physical exercise on inhibitory control in healthy young students. The results showed that high-intensity exercise had a positive effect on inhibitory control.

Summary: This study aimed to compare the physiological and perceptual responses during moderate intensity exercise with different levels of blood flow restriction (BFR) and high intensity exercise without BFR. The results showed that regardless of pressure, exercise with BFR led to increased heart rate, blood lactate levels, and perceived exertion, while tissue oxygen saturation decreased. Furthermore, the physiological responses induced by different levels of BFR during moderate intensity exercise were similar.

Summary: The study found that the release of IL6 and lipid peroxidation in response to half-squat exercises were greater in men than in women at equivalent workloads. There were no significant differences in muscle damage parameters between sexes or time points. Women did not show variations in the studied variables when compared among different time points.

Summary: This study found that vigorous exercise can attenuate the cortisol response to a subsequent stressor task, with the effect being proportional to the intensity of the exercise. The cortisol released from exercise suppresses the subsequent cortisol response to psychosocial stressor.

Summary: The study compared the effects of programmed fluid intake and thirst-driven fluid intake on prolonged cycling performance and exercise associated muscle cramps. The results showed that programmed fluid intake can increase power output during a 20 km time-trial, but there was no significant difference in the prevalence of muscle cramps of the plantar flexors between the two drinking conditions.

Summary: The immune response in burn patients is often extreme and abnormal. Understanding the immune effects of thermal injury is necessary to improve patient outcomes. This study shows that after burn injury, immune cells persistently increase in number, unlike in normal wound healing. The study also reveals high levels of chemokines and pro-inflammatory cytokines in burn tissue. The local immune response in burns is similar to the systemic immune reaction, but differs in neutrophil maturity and lymphocyte composition.

Summary: This study found that at the same moderate-to-vigorous exercise intensity, running appears to result in a greater transient sclerostin response compared with cycling. Meanwhile, the responses of bone markers, PTH, and irisin are similar between the two exercise modes.

Summary: Aerobic exercise with blood flow restriction can improve muscular function and aerobic capacity. The pressure of the cuff used in blood flow restriction influences physiological responses to the exercise. Blood flow and tissue oxygenation decrease, while neuromuscular function is impaired during cycling with blood flow restriction. Cycling with moderate pressure may be a potential alternative to traditional high-intensity aerobic exercise.

Summary: The aim of this study was to evaluate the implementation of a laboratory-based exercise intervention in the community for individuals with Parkinson's disease. The results showed that consistent attendance and exercise intensity were achievable in a community-based exercise program. There were no significant differences in adherence and intensity variables based on disease severity, age, or sex.

Summary: Anxiety is common in people with major depressive disorder (MDD), but the effects of acute exercise on anxiety in MDD are not known. This study aimed to determine the optimal acute exercise intensity for reducing state anxiety in women with MDD and the duration of the anxiety reduction. The results showed that prescribed moderate intensity exercise significantly reduced state anxiety in women with MDD for at least 30 minutes after exercise.

While the majority of participants expressed a desire to expand their knowledge on 'Nutritional Psychiatry,' only a very small percentage rated their nutrition education as 'very good.'

Summary: Lactose intolerance is one of the major causes of irritable bowel syndrome, but its pathophysiology is still unclear. This study retrospectively assessed the impact of histamine intolerance on exhaled hydrogen levels in lactose intolerance patients. The results showed that lactose intolerance patients with histamine intolerance had significantly higher levels of exhaled hydrogen and a higher number of patients with gastrointestinal symptoms during breath tests.

Summary: This study investigated the immunomodulatory effects of aronia juice polyphenols, finding that plasma polyphenol levels increased after intervention and that aronia juice had inhibiting effects on the differentiation and activation of certain immune cells. In addition, aronia juice stimulated the emergence of a specific cell population. These findings highlight the individual hormetic effects, the importance of the food matrix for bioactivity, and the need for further investigation into specific physiological features such as the gut microbiota in personalized nutrition.

Summary: Regular physical activity can improve immune surveillance, reduce the risk of COVID-19 infection, and potentially enhance the efficacy of COVID-19 vaccines. Additionally, physical training and rehabilitation can help improve physical fitness, quality of life, and immune health in patients with sustained morbidity from COVID-19.
