Summary: This study aimed to investigate the effects of 12 weeks of sprint interval training (SIT) combined with need-support on post-exercise food consumption. The results showed that SIT with psychological need-support significantly decreased post-exercise energy intake from snacks, while traditional moderate-intensity continuous training (MICT) did not affect food intake. SIT with need-support is well-tolerated in physically inactive individuals with overweight and offers an alternative to traditional exercise prescription.

Summary: The current study investigated the effects of Alpha-Glycerylphosphorylcholine (A-GPC) on heart rate variability (HRV) and hemodynamic responses following a sprint interval exercise (SIE) in overweight or obese women. The results showed that A-GPC consumption led to increased levels of HRV variables and faster recovery of HRV and blood pressure after strenuous exercise in this population, suggesting that it may beneficially modify cardiac autonomic function.

Summary: Short-term dietary nitrate supplementation can enhance performance in submaximal endurance and short-duration, maximal-intensity exercise. A study found that participants who ingested NO3--rich beetroot powder had higher plasma [NO3-] and [NO2-] levels, and showed improved mean power output and faster muscle oxygenation kinetics during an end-sprint. These findings suggest that NO3- supplementation can improve end-sprint performance in endurance events when taken before and during exercise.

Summary: The aim of this systematic review was to determine the acute effects of interval training (IT) on gait patterns and running kinematics in endurance runners. It was found that short recovery periods in anaerobic and short aerobic interval sessions would increase stride frequency, contact time, and vertical displacement of the center of mass, while long recovery periods in aerobic interval sessions would not induce significant fatigue or modifications in gait patterns. Coaches and athletes should consider the type of IT and the relative intensity and recovery periods to prevent excessive fatigue that can negatively affect running kinematics.

Summary: In recent decades, there have been numerous studies investigating the effects of oral caffeine intake on fat oxidation. However, there has been no bibliometric analysis to assess the research activity in this field. This study conducted a bibliometric and visual analysis to assess the scientific output regarding oral caffeine intake and fat oxidation rate. The findings demonstrate that this is a nutrition research area with a strong foundational base of scientific evidence, and future research should focus on the effects of sex and caffeine tolerance on fat burning, as well as translational research in ecologically valid contexts.
