Summary: The study aimed to develop a sprint interval protocol that stimulates both anaerobic and aerobic systems while maximizing power output and minimizing fatigue. The results showed that peak power output could be maintained with recovery durations of 45 and 30 seconds, but declined significantly with a 15-second recovery period.

Summary: The study investigated the effects of low and moderate doses of caffeine from coffee on repeated sprint performance and plasma catecholamine concentration in trained female team-sport athletes. Results showed that caffeine ingestion can enhance the average peak power score during repeated sprints, supporting caffeine supplementation via coffee as a nutritional ergogenic aid for trained female team-sport players.

Summary: The study found that a high-intensity warm-up (HIW) increases anaerobic system contributions in a 100-m sprint compared to a low-intensity warm-up (LIW), but has no significant effect on sprint time trials, although it may improve times.

Summary: Ischemic preconditioning has been reported to enhance exercise performance, but the reproducibility and robustness of its effects are variable, likely due to considerable variability among study methodologies. Future research should focus on improving methodological consistency to optimize the IPC protocol.

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: Ice-hockey players need high acceleration and speed sprint abilities, but there is no clear sprint distance to measure these capabilities. This meta-analysis summarizes the reference values for different sprint distances and suggests appropriate testing protocols. The analysis included 60 studies with a total of 2254 males and 398 females aged 11-37 years. The recommended distances for peak acceleration and speed are 6.1 m and 30 m respectively.

Summary: The study found that sprint interval exercises (SIT) with gravity-induced blood flow restriction (G-BFR) led to lower mechanical, cardiorespiratory, and skeletal muscle oxygenation responses compared to other conditions. Training with BFR at 60% occlusive pressure (BFR60) resulted in higher blood accumulation in working muscles, potentially affecting cellular stress. Both hypoxia (HYP) and G-BFR induced local hypoxia, with G-BFR showing higher levels during both exercise bouts and recovery periods.

Summary: The study aimed to investigate the association between sprint power and aerobic power output during a graded peak exercise test, and validate the prediction models of power output based on sprint power and personal characteristics. The best model to predict power output included sprint power, BMI, and other variables. While relative agreement was excellent, absolute agreement was found to be low.

Summary: This study compared muscle deoxygenation and reoxygenation kinetics during a sprint interval protocol under four different modalities. It found that reoxygenation was delayed in the blood flow restriction condition, and reoxygenation was slower in the gravity-induced blood flow restriction condition.

Summary: This study evaluated the feasibility of ultrasound assessment of muscle glycogen in horses. The results showed significant differences in greyscale intensity between different muscle tissues, and a significant increase in intensity in one muscle after exercise, indicating changes possibly associated with glycogen utilization.

Summary: This study compared the effects of plyometric training (PT) and strength training on muscle strength, sprint, and lower limb functional performance in soccer players. It found that strength training was more effective than PT in improving muscle strength, sprint, and lower limb functional performance in male soccer players.

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: This study examined the relationship between repeated sprint ability test and match-related physical performance in male youth soccer players. The results showed that differences in 5 x 30-m performance explained the amount of sprinting activity performed during the match, supporting the construct and ecological validity of the protocol.

Summary: This study explores the acute effects of sodium nitrite on the bioenergetic behavior of cultured rat myocytes. The results show that sodium nitrite does not affect mitochondrial coupling efficiency but stimulates glycolytic ATP production rate and shifts myocytes to a more glycolytic bioenergetic phenotype. Additionally, sodium nitrite decreases the oxygen cost of total ATP synthesis in myocytes.
