Female subjects have been historically excluded from biomedicine and other related areas of study [1]. Such exclusion has disadvantaged females prevented a fuller understanding biology. Therefore, in 2016, the National Institute Health (NIH) mandated that all NIH-funded animal human studies consider sex as biological variable (e.g., [2]). Yet, not welcomed with open arms, most likely because many researchers believe they need to increase overall sample size two sexes compared using only one Recently, Philips colleagues published PLoS Biology article titled “Statistical simulations show scientists by default when including both vivo studies” [3]. As indicated their title, authors concluded recommended no sexes, which was based on set exploring simple but – claim scenario. Their conclusion is great news for who feared coping increased experiment sizes costs.

Phylogenetic comparative methods are important tools in biology, providing insights into the way traits evolve. There many technical resources describing how these work. Our aim here is to complement with an overview of types biological questions that can be addressed by different and outline potential pitfalls considerations when embarking on studies. First, we introduce what why they important. Second, used understand when, where, frequently Third, examine coevolution within between species studied, along patterns causality. Finally, discuss approach analyses ways which data, such as published relationships, omic, remote sensing integrated.

A recent article claimed that researchers need not increase the overall sample size for a study includes both sexes. This Formal Comment points out assumed two sexes to have same variance, and explains why this is unrealistic assumption.

Abstract While psychologists have extensively discussed the notion of a “theory crisis” arising from vague and incorrect hypotheses, there has been no debate about such crisis in biology. However, biologists long communication failures between theoreticians empiricists. We argue failure is one aspect theory because misapplied misunderstood theories lead to poor hypotheses research waste. review its solutions compare them with methodology-focused proposed for replication crises. conclude by discussing how promoting inclusion, diversity, equity, accessibility (IDEA) theoretical biology could contribute ameliorating breakdowns theory-empirical cycle.

The purpose of this study was to investigate the benefits a 12-week plyometric training program intervention on lower limb joint mobility, explosive strength, advanced layup success rates, and injury rates. recruited 15 collegiate male basketball players as participants. They underwent five times per week, each lasting two hours, additionally received twice week. utilized image processing software (ImageJ, version 1.54f, National Institutes Health, Bethesda, MD, USA) measure mobility during take-off phase employed force plate assess strength limbs jump. Furthermore, examined rate layups—including crossover layups, spin straight-line layups—as well sports rate. results demonstrated that significantly enhanced hip, knee, ankle with strong positive correlation between these variables. improved strength. layups increased from 50% 72%, while decreased 18% 8%. In conclusion, participants’ which in turn performance reduced Although provided preliminary evidence supporting effectiveness training, further research is needed examine its long-term effects other influencing factors.

Background: Sample size estimation is an essential step in the design of randomized controlled trials (RCTs) evaluating a treatment effect. critical variable determining statistical significance and, thus, it significantly influences RCTs’ success or failure. During COVID-19 pandemic, many RCTs tested efficacy convalescent plasma (CCP) hospitalized patients but reported different efficacies, which could be attributed to, addition to timing and dose, inadequate sample estimates. Methods: To assess effect with CCP patients, we searched medical literature between January 2020 March 2024 through PubMed other electronic databases, extracting information on expected effect, power, level, measured efficacy. Results: A total 32 were identified. While power level highly consistent, heterogeneity was relevant. Approximately one third did not reach planned for various reasons, most important being slow patient recruitment during pandemic’s peaks. primary outcome favor had significant lower median absolute difference than unfavorable (20.0% versus 33.9%, P = 0.04). Conclusions: The analyses sizes reveal that underestimated number participants needed because excessively high expectations efficacy, these studies low power. This, combination lower-than-planned cases controls, have further negatively influenced outcomes RCTs.

Recent studies have shown that lower-limb plyometric training can effectively enhance muscle strength and explosiveness, which are particularly important for improving jumping ability. The purpose of this study was to evaluate the effects on vertical, lateral, horizontal abilities, their subsequent impact basketball shooting performance sports injury prevention. A quasi-experimental design used, recruiting 30 male college-level players from Taiwan, who were randomly assigned an experimental group (n = 15) a control 15). Both groups participated in 2 h daily, while additionally engaged twice week. results revealed significant improvements several key areas, including rate force development (RFD), ground reaction (GRF), jump height, distance, both vertical forces, across jumps. Specifically, jumps required highest force, followed by lateral jumps, with (step-back) requiring least. optimal angles resultant during take-off found be between 66.1° 66.8° 56.2° 57.2° step-back did not show variation angle. In terms performance, demonstrated significantly better post-test all three types shots, accuracy observed shot, lowest shot. Furthermore, experienced substantial reduction rates, decreasing 6%. These findings indicate only enhances but also contributes prevention strengthening muscles. This provides theoretical basis coaches develop comprehensive programs improve athletic reduce risk.
