Summary: This study compared the effects of high-intensity interval training (HIIT) and sprint interval training (SIT) on maximal oxygen uptake (VO2max), anaerobic capacity, and endurance performance in women. The results showed that HIIT significantly increased VO2max in women, while SIT led to more training injuries. Both training protocols improved running performance in women.

Summary: Analyzing the modeling of intermittent work capacity in elite cyclists, the Bartram adjustment was found to be an improvement over the Skiba 2 model, with a focus on W' in this population. However, in the specific context of team pursuit races, all models were too variable for effective use, indicating the need for exploration of individual recovery rates beyond population-specific rates.

Summary: This study examined the suitability of a single ramp incremental test to accurately predict critical power (CP) and W' values. The results showed that the power output (PO) at the respiratory compensation point (RCP) corresponded to CP, and W0 could be calculated from the work done above RCP. However, due to the underestimation and large variability of W' in ramp exercise, the interchangeable use of CP and W' values derived from constant load and ramp exercise is not recommended, especially when accurate estimates or performance predictions are desired.

Summary: This study compared three different protocols to assess V-max in athletes with higher or lower training status. Results showed that athletes with higher aerobic training status had faster oxygen uptake kinetics and lower differences in V-max between protocols, particularly in CP2 vs DP.

Summary: The study found that in XCO mountain bike races, athletes exhibit varying power output patterns and pacing strategies within different laps. As the race progresses, actions exceeding critical power tend to decrease in magnitude in later laps, while the number and duration of these actions remain relatively consistent.

Summary: This study compares the VO2max, MAS, and spatiotemporal parameters between sub-elite middle- and long-distance runners and endurance non-runners. The findings show that middle- and long-distance runners achieve a faster MAS compared to non-running endurance athletes, despite having similar VO2max. This could be attributed to a greater mechanical efficiency and the ability to modify stride length to achieve faster speeds.

Summary: The aim of this study was to evaluate the effects of interval training performed in hypoxia on aerobic capacity and second ventilatory threshold in young, untrained men. The results showed that compared to training in normoxia, interval training in hypoxia significantly improved maximum oxygen uptake and power output at the second ventilatory threshold.

Summary: The purpose of this study was to investigate the anthropometrical and physiological determinants of laboratory and on-snow performance in competitive adolescent cross-country skiers. The results demonstrate that V?O-2 peak has a significant impact on overall skiing performance, while upper-body strength and BMI are more correlated to sprint performance. Laboratory performance is primarily influenced by physiological factors, while on-snow performance is affected by various factors.

Summary: This study compared the oxygenation response in the vastus lateralis muscle during supramaximal and maximal tests and investigated the usefulness of muscle oxygenation measurements in assessing anaerobic and aerobic capacity. The results showed that there were no significant differences in the SmO2 indices between the two tests, and gender did not impact muscle oxygenation regardless of test type. In the graded exercise test, the half time required for SmO2 to reach the maximal value correlated with VO2max and test duration, indicating the usefulness of SmO2 measurements in assessing aerobic capacity in speed skaters. However, the Wingate test did not show significant correlations between exercise indices and muscle oxygenation indices, suggesting limited diagnostic value of SmO2 measurements in assessing anaerobic capacity.

Summary: This study found a high prevalence of 25-OH vitamin D insufficiency in male professional indoor athletes, with insufficient vitamin D concentrations associated with lower maximal aerobic power. Maintaining 25-OH vitamin D concentrations of > = 30 ng/mL is crucial for optimal physical performance in these athletes.

Summary: The study aimed to investigate the correlation between aerobic power, maximal anaerobic power, anaerobic capacity, and maximal accumulated oxygen deficit with 800 m double poling time trial performance in a ski ergometer. It also explored the relationship between time to exhaustion and maximal accumulated oxygen deficit and their relation to anaerobic power reserve. The results suggest that focusing on aerobic and maximal anaerobic power is more important than anaerobic capacity in explaining performance in a 3-minute event.

Summary: The study found significant decreases in muscle oxidative capacity and physical activity levels in patients with severe COPD compared to smokers with normal lung function. The research also revealed a close association between metabolic abnormalities and impaired mitochondrial function and the accumulation of triacylglycerides in severe COPD patients.

Summary: Individuals with cerebral palsy (CP) have higher energy expenditure and oxygen cost during walking compared to age-matched typically developing (TD) individuals, with a strong relationship across Gross Motor Function Classification System (GMFCS) levels. Oxygen cost is considered the preferred parameter to assess walking efficacy in CP, but there is a knowledge gap in age-related changes of walking efficiency across GMFCS levels. Further longitudinal research is needed to explore the energetics of walking in this population.

Summary: This study compared acute changes in tendon blood flow and oxygenation after isometric exercise at different intensities. The results suggest that the tendon hyperemic response is fully achieved at approximately 50% of maximal voluntarily isometric contraction (MVIC). Moderate loading seems to be sufficient to stimulate tendon healing.

Summary: The final steps of the O-2 cascade during exercise depend on the product of the microvascular-to-intramyocyte PO2 difference and muscle O-2 diffusing capacity (DmO(2)). Non-invasive methods to determine DmO(2) in humans are currently unavailable. Muscle oxygen uptake (m.VO2) recovery rate constant (k), measured by near-infrared spectroscopy (NIRS) using intermittent arterial occlusions, is associated with muscle oxidative capacity in vivo.

Summary: The study found that COPD patients had higher CAC, lower muscle oxidative capacity, and lower self-reported PA levels compared to controls. Multivariate analysis revealed a significant negative association between CAC and the difficulty score of PA. These findings suggest that COPD patients with elevated CAC may experience greater difficulty in performing daily activities.
