Summary: In female Australian Rules football players, the best approximation of maximal aerobic speed (MAS) is achieved through a 1.4-1.5 km time trial (TT), while MAS can be predicted from any distance between 1.2 and 2.2 km. The TT-derived MAS provides an efficient method for quantifying aerobic fitness and prescribing future training intensities.

Summary: Endurance training has been proven effective in treating adolescents with major depressive disorder. This study examined the exhaustion criteria during a cardiopulmonary exercise test (CPET) for adolescents with MDD, and compared the values with control values. The results showed that fewer adolescents with MDD achieved the exhaustion criteria and had significantly lower cardiorespiratory fitness compared to the control group.

Summary: Aerobic fitness is consistently associated with superior cognitive control performance, potentially through the activation of the locus-coeruleus. However, in college-aged adults, phasic activity of the locus-coeruleus does not mediate the relationship between aerobic fitness and cognitive task performance.

Summary: This study found that blood flow restriction training can significantly increase peak oxygen uptake (VO(2)peak), while the speed at first and second lactate threshold did not change significantly. Blood flow restriction training can be considered as an effective means to improve relevant performance surrogates in trained swimmers.

Summary: The study evaluated the factors explaining variance in thermoneutral maximal oxygen uptake (?VO2max) adaptation to heat acclimation (HA). Iso-intensity training in heat was performed by 71 participants, and their thermoneutral ?VO2max change pre-to-post HA was evaluated. Partial least squares regression was used to analyze the variance using 24 variables. The results showed that iso-intensity HA improved ?VO2max 63% of the time, with exercise intensity, ambient temperature, HA training days, total exposure time, baseline body mass, thermal sensation, whole-body mass losses, and the number of days between HA and post-testing being important considerations.

Summary: The aim of this study was to develop distributions of VO2max for prepubertal boys using cycle ergometry based on existing measured values in the literature. The study followed PRISMA guidelines and searched one database for peak and maximal VO2 values in healthy boys under 11 years old. The results showed that absolute VO2max increases with age, but mean relative VO2max does not change. There were differences in absolute and relative VO2max between recent studies and boys from different countries. Heavier boys had lower cardiorespiratory fitness, and body mass seemed to be increasing faster with age in the USA compared to other countries. New reference values for cardiorespiratory fitness in prepubertal boys were presented using cycle ergometry.

Summary: Cardiorespiratory fitness (CRF) is significantly related to morbidity and mortality in patients with obesity. This study shows that age and BMI are independent determinants of CRF in obese patients.

Summary: The study found that 12-week vitamin D supplementation can increase serum vitamin D levels and improve inflammatory status in young healthy men with vitamin D deficiency, but has no significant impact on cardiorespiratory fitness.

Summary: The altitude of birth/childhood may influence the peak power output and estimated maximum oxygen uptake in male Colombian road cyclists. Cyclists born at high altitudes are more likely to be successful. Riders in the low altitude group have lower values of power output and maximum oxygen uptake compared to cyclists in the moderate and high altitude groups.

Summary: This study developed a new equation for predicting VO2max in competitive cyclists, which showed higher accuracy compared to the traditional ACSM equation. The new equation is recommended for use in medicine and sports practice for competitive cyclists.

Summary: Animal studies have shown that physical exercise can protect memory from the effects of sleep deprivation. This study aimed to investigate whether high cardiorespiratory fitness (V·O2peak) is associated with enhanced episodic memory encoding after one night of sleep deprivation. The results suggest that maintaining high levels of cardiorespiratory fitness may have a protective effect against the disruptive effects of sleep deprivation on memory.

Summary: A model structure was established to estimate the respiration rate of Phalaenopsis and Chrysanthemum as a function of oxygen concentration and temperature, facilitating the management of quality loss during storage and transport of plantlets and cuttings. The models can be used to estimate a dynamic oxygen consumption rate profile during storage and transport.

Summary: This study aimed to investigate the proportion of pwMS who achieve the maximal oxygen consumption criteria and to identify participant characteristics that limit maximal exercise performance. The findings showed that only 60% of the participants met the criteria for respiratory exchange ratio = 1.10, and a smaller percentage achieved the criteria for oxygen consumption plateau or heart rate. Disability status, gender, disease course, and body mass index were associated with the attainment of maximal effort.

Summary: Predicting VO2max is crucial for athletes in determining endurance capacity, performance monitoring, clinical diagnostic procedures, and disease management. This study aimed to find the most suitable equation to predict VO2max in competitive cyclists. The results showed that the FRIEND equation accurately predicted VO2max in both male and female athletes, with high correlation and minimal errors compared to other equations. This highlights the potential value of using the FRIEND equation for predicting VO2max in competitive cyclists.

Summary: The study found that the respiration chamber is a valid and reproducible method for measuring VO(2)max, with high concordance and no significant differences between different tests. New research opportunities such as maximal exercise testing during 24-hour measurements are possible in the respiration chamber.
