Summary: This paper provides an overview of the bioavailability, efficacy, and regulatory status of creatine monohydrate (CrM) and other marketed forms of creatine. It concludes that only CrM has substantial evidence supporting its bioavailability, efficacy, and safety. The paper recommends the use of CrM in dietary supplements and calls for research to substantiate claims about the efficacy and safety of other forms of creatine before they are marketed.

Summary: The consumption of beetroot juice rich in nitrates has been shown to improve sports performance, particularly in fatigue resistance during repeated sprints. Different dosages have been proposed for chronic and acute intake, with chronic intake leading to better results over a period of days, while acute intake closer to physical exertion may also yield effective outcomes. This systematic review reveals potential benefits in enhancing fatigue resistance during repeated sprints by consuming nitrates derived from beetroot juice.

Summary: The study aimed to investigate the effects of caffeine ingestion on upper-body intermittent strength endurance performance of combat sports athletes. Caffeine intake significantly increased both total repetitions and maximal isometric handgrip strength compared to a placebo condition. While heart rate, lactate concentration, and perceived exertion increased linearly throughout the test, they did not differ significantly between caffeine and placebo conditions. Findings suggest that caffeine could help maintain high levels of maximal handgrip and endurance strength in upper limbs for athletes in grappling sports.

Summary: This study demonstrates that chewing caffeine gum significantly improves exercise tolerance in well-trained runners. Despite decreased neuromuscular responses after exhaustion, athletes were able to run a longer distance in the caffeine condition, suggesting a neuromuscular contribution to the performance enhancement induced by caffeine.

Summary: The meta-analysis found that caffeine ingestion significantly enhances rate of force development (RFD), particularly during resistance exercises. Higher doses of caffeine showed larger effects on RFD improvement. However, the effects were not significant during countermovement jump tests.

Summary: Studies have shown that in older females, supplementation with creatine combined with resistance training can significantly increase upper body strength, and increase both upper and lower body strength when training lasts at least 24 weeks. Further high-quality studies are needed to confirm these findings.

Summary: Algae such as spirulina and chlorella have been shown to improve cardiovascular risk factors, anemia, immune function, and arterial stiffness. However, the impact of oxidative stress biomarkers reported in previous studies is still debated, calling for further research. Recent studies have demonstrated the potential of algae supplementation in enhancing submaximal exercise performance, although the exact mechanisms behind these improvements remain unclear.

Summary: This study aimed to analyze the effect of exercise-induced hyperpnea on gross efficiency (GE) and anaerobic capacity estimates during a self-paced 3-min supramaximal cycle time trial (TT). The study found that the hyperpnea-corrected models generated lower GE and higher anaerobic capacity during the supramaximal TT, compared to the conventional models. The linear models for estimating anaerobic capacity are likely to generate underestimated values.

Summary: This study assessed the number of emergency department (ED) presentations in Queensland during the low COVID-19 case period of 2020-2021. The analysis showed a 19.4% decrease in ED presentations during the lockdown period compared to the pre-pandemic period. The decline varied across different triage categories and diagnostic groups, with presentations for less urgent conditions and mental health problems remaining below predicted levels in the post-lockdown period.

Summary: This article provides a systematic and quantitative review and evaluation of the alignment of learning outcomes and the quality of peer-reviewed literature reporting gamification in pharmacy education. The findings highlight the inconsistent reporting quality, misalignment between intended learning outcomes and reported outcomes, overreliance on student perceptions as primary data, and lack of reference to reporting guidelines. The review identifies evidence gaps and emphasizes the need for improved research quality, alignment of learning outcomes with evaluation, and use of reporting guidelines in gamification studies.

Summary: The protective effect of physical activity on breast cancer incidence may be partly mediated by inflammation. Meta-analyses of intervention studies showed that exercise interventions reduced levels of circulating inflammatory biomarkers, providing support for the biological plausibility of the physical activity-inflammation-breast cancer pathway.

Summary: This Delphi study aimed to gather expert opinions and provide recommendations for best practices when using electrical stimulation during maximal voluntary contractions. The study found that electrical stimulation can validly assess voluntary activation in specific circumstances, such as during maximal contractions, and can be applied to either the muscle or the nerve. The recommendations from experts in this study can guide researchers in making informed decisions when designing studies involving electrical stimulation for the assessment of voluntary activation.

Summary: This scoping review identified a limited number of studies that describe the long-term development of training and performance-determining factors in male and female endurance athletes. The findings suggest a non-linear increase in training volume over time and improvements in submaximal variables and maximal performance indices. However, the development of VO2max showed inconsistent results. No evidence was found regarding sex differences in the development of training or performance-determining factors among endurance athletes.

Summary: This study systematically reviewed human longitudinal exercise interventions and found that moderate to high-intensity exercise for 30-90 min, at least 3 times per week (or 150-270 min per week) for 8 weeks or more, is likely to produce changes in the gut microbiota. Exercise appears to be effective in modifying the gut microbiota in both clinical and healthy populations. More rigorous methodology is needed for future studies to improve the certainty of the evidence.

Summary: This study systematically reviewed prior research on the effects of contact/collision sport participation on neurometabolite levels in the absence of concussion. The review found that N-acetylaspartate (NAA) and total creatine (tCr) decreased during the sports season, but glutamate-glutamine (Glx), myo-inositol (mI), and total choline (tCho) did not show significant changes. Several moderating factors, including sex, sport played, brain region, and the MRS quantification approach, were found to influence the results. The study suggests that contact/collision sport participation has the potential to alter neurometabolites measured via H-1 MRS in the absence of concussion, but further research is needed.

Summary: Pseudomonas aeruginosa (P. aeruginosa) is a problematic bacterium due to its multidrug resistance (MDR) phenotype. It exhibits intrinsic and acquired resistance to many antibiotics, and efflux pumps, particularly the Mex pumps, play a crucial role in driving MDR. Developing efflux pump inhibitors (EPIs) holds great potential for overcoming MDR and restoring the efficacy of antipseudomonal drugs.

Summary: This study investigated the availability, visibility, advertising, and promotion of low-alcohol beverages (LABs) in licensed venues in Australia. The findings showed that LABs were available in about half of the venues audited, but their visibility and promotion were poor. There is a need to improve access to and promote lower alcohol alternatives within licensed venues.

Summary: The aim of this research was to evaluate affective learning in participants of an extended, immersive, gamified pharmacy simulation. Affective learning was assessed via analysis of student reflective journals. From 2016 to 2018, 123 students participated in the simulation, generating 734 reflective journal entries for analysis. Overall, affective learning was evident, and its level increased over the course of the simulation. This was primarily associated with the improvements of female students.
