Summary: This study investigates the relationships between maximal aerobic speed (MAS), lactate threshold in per cent of peak oxygen uptake (LT), and velocity at LT (LTv) in cross-country skiers. The results suggest that LT has a minor impact on LTv, while MAS is the predominant factor determining LTv.

Summary: The study found that the recommended exercise intensity definition based on percentages of peak HR and peak VO2 may misclassify the effective exercise intensity. Using a ventilatory threshold-based approach may be more suitable for defining an appropriate level of exercise intensity, especially in cardiac patients.

Summary: The study demonstrates a linear relationship between heart rate variability threshold (HRVT) and the first ventilatory threshold (VT1) in a population with cardiac disease, where reaching a DFA a1 of 0.75 is associated with VT1. After a training intervention, changes in VT1 align with those in HRVT, confirming the relationship between these parameters.

Summary: Lactate plays a crucial role in connecting glycolytic and mitochondrial oxidative metabolism, and serves as a major precursor for gluconeogenesis. Blood lactate concentration is sensitive to metabolic states, as lactate rates of appearance and disposal in circulation change in response to exercise and metabolic disturbances. The lactate flux rates are highest during moderate intensity exercise in endurance-trained individuals with superior oxidative capacity. In contrast, poor metabolic fitness is associated with a diminished ability to utilize lactate. The concept of lactate metabolic clearance rate, which increases at the onset of exercise, is discussed, along with the application of the lactate clamp methodology in studying lactate disposal capacities.

Summary: The aim of this study was to evaluate the physiological and metabolic responses to running with whole-body electromyostimulation (wbEMS) compared to running without electromyostimulation (control, CG). The results showed that wbEMS induced earlier fatigue and a shift in energy metabolism toward fat utilization. Therefore, wbEMS can be considered as an alternative training stimulus that is easy-to-apply and effective during endurance training.

Summary: This study compared oxygen intake and heart rate at the first ventilatory threshold with parameters derived from a predefined DFA a1 value, showing strong agreement between the two in measuring low intensity exercise. Results suggest that reaching a DFA a1 value of 0.75 in an incremental treadmill test is closely associated with crossing the first ventilatory threshold, indicating potential for utilizing DFA a1 as a valid guide for low intensity training zones.

Summary: This study investigated the chronic effects of supplementation with a biodynamic and organic olive fruit water phytocomplex on exercise performance and recovery. Results showed that the supplement improved exercise performance and acute recovery. Further research is needed to determine the optimal dosage and if it can enhance long-term training adaptations.

Summary: The study found that a K-LCHF diet did not have significant impact on aerobic capacity and exercise performance, but did have an effect on substrate oxidation response to respiratory exchange rate. Further high-quality interventions are needed to explore the effects of a K-LCHF diet on various endurance training programs.

Summary: Gut microbes play a crucial role in enhancing exercise performance and regulating metabolism in mice. Germ-free mice had reduced aerobic exercise capacity, lower body weight gain, and lower fat mass compared to mice with a healthy microbiome. The absence of gut microbes impaired glucose utilization and led to decreased exercise performance. Identifying key microbial species could be the focus of future research.

Summary: COVID-19 has a deteriorating impact on health, particularly for endurance athletes who rely on consistent training. This study examines the effects of mild COVID-19 on sleep, psychology, and cardiopulmonary exercise test results. The findings indicate a decline in exercise performance, which is influenced by sleep quality and psychological factors. It is important for medical professionals to encourage proper mental health and sleep among athletes recovering from COVID-19 infection.

Summary: This study examined the effects of two different types of endurance training on cardiovascular health indicators in women. The results showed that both types of training had positive effects on lipid panel variables, body composition, and endurance capacity, with treadmill-based endurance exercise showing greater improvement in endurance capacity compared to choreographed aerobic-endurance training.

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.
