Summary: Brief, intense interval training improves V_O2max through various physiological changes, including increased maximal cardiac output and blood volume, as well as changes in capillary and mitochondrial density. However, the specific mechanisms underlying these improvements are still unclear and require further investigation using contemporary technologies.

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 study showed that performing 6 sessions of HIIT over 5 days was as effective as doing 6 sessions over 2 weeks in increasing VO2max and endurance capacity, and even more effective in improving submaximal exercise fat oxidation.

Summary: This study aimed to verify the training session volume and t90VO(2max) under different work and recovery settings during high-intensity intermittent training. The results showed that the 30s/30s protocol was the most appropriate for increasing training volume, while the 40s/20s protocol may optimize training time effectively.

Summary: This study compared the effects of 100- and 200-m interval training in swimming on temporal, perceptual, and physiological responses. The results showed that there were no significant differences in oxygen uptake, blood lactate, and perceived exertion between the two protocols. Both protocols were effective for aerobic power enhancement, but swimmers perceived the 100-m interval training as less difficult than the 200-m training.

Summary: Endurance training, especially single leg cycling, can significantly improve maximal oxygen consumption in heart, kidney, and liver transplant recipients by enhancing peripheral oxygen extraction and utilization. Single leg cycling training is as effective as double leg cycling training in improving cardiorespiratory fitness in these patients. Peripheral factors play a significant role in limiting maximal oxygen consumption in transplant recipients.

Summary: This study aimed to investigate the effects of a gym-based strength training intervention on biomechanics and intermuscular coordination patterns during short-term maximal cycling. The results showed that leg strength and crank power significantly increased following the strength training intervention, accompanied by changes in muscle activity patterns.

Summary: The study established equations to convert 3,000 m run performance into predicted V?O-2max, with validity statistics provided. The correlation between V?O-2max and average 3,000 m run speed was shown to be high, making the 3,000 m test a time-effective alternative aerobic fitness test.

Summary: This study investigated whether larger splenic emptying enhances excess post-exercise O-2 consumption (EPOC) after aerobic exercise cessation. It was found that during moderate-intensity supine cycling, spleen volume decreased by about 5%, resulting in a transient increase in red cell count and an increase in cardiovascular variables. Significant correlations were observed between the percent change in spleen volume and both EPOCfast and tau<(V)over dot>O-2.

Summary: Combining the LCHF diet with HIIT can effectively reduce weight and fat, increase VO2max, and prevent muscle mass loss during LCHF, while fat mass and fat-free mass remain relatively unchanged. Further research may be necessary to clarify the effects of other types of exercise on body composition and physical performance during LCHF.

Summary: The study showed that both low-volume short-duration sprint interval training (SIT) and traditional endurance training (ET) significantly improved maximal oxygen uptake and intermittent endurance performance after 6 weeks of training. However, SIT was more effective in improving aerobic capacity and intermittent endurance performance, while ET was better at maintaining speed and power indices.

Summary: This study examined the correlations between time and estimated power output (EPO) for a run field test and VO2 max obtained from cardiopulmonary exercise testing (CPET). The results showed that EPO had a stronger correlation with VO2 max compared to time.

Summary: This study examined the heart rate variability (HRV) in cyclists after sprint interval training and its implications for assessing physical fatigue. The results showed that HRV did not reflect the onset of fatigue during sprint interval training, while it was correlated with average power output.

Summary: The aim of this study was to determine the predictors of change in maximal oxygen uptake (ΔV?o(2)max) in response to a polarized training program. The results showed significant correlations between ΔV?o(2)max and training status and baseline measures of VEmax·LBM-1, RMSSD, and V?o(2)max·LBM-1. A regression equation was developed to predict the change in V?o(2)max based on these measurable variables.

Summary: This study compared the effectiveness of a block training program and a polarized training program in developing aerobic capacity in trained mountain bike cyclists. The polarized training program was more effective in developing maximal oxygen uptake (VO(2)max), while both programs showed similar results in developing other parameters of cyclists' aerobic capacity.

Summary: Individual changes in resting heart rate variability have been found to be variable among Polish cyclists during training, with some showing increased HF values during high-intensity training periods while others showed increased HF values during low-intensity training periods. Cyclists with lower baseline HRV values exhibited increased activity of the parasympathetic nervous system, while those with higher baseline values showed an opposite trend.
