Core training effects on power

BACKGROUND: The capabilities of the biomotors are essential to the success of the taekwondo athlete. This study aimed to compare eight weeks of functional training and traditional resistance on the bio-motor capacities of elite female taekwondo athletes. METHODOLOGY: Seventeen elite taekwondo athletes (mean age = 21.7 years, mean height = 167.2 cm and mean weight = 60.8 kg) volunteered to participate in the study. They were randomly divided into two groups: functional training (FT) and traditional resistance training (TRT)...

Hybrid transformer-based segmentation approaches have shown great promise in medical image analysis. However, they typically require considerable computational power and resources during both training and inference stages, posing a challenge for resource-limited medical applications common in the field. To address this issue, we present an innovative framework called Slim UNETR, designed to achieve a balance between accuracy and efficiency by leveraging the advantages of both convolutional neural networks and transformers...

BACKGROUND: The impact of young drivers' motor vehicle crashes (MVC) is substantial, with young drivers constituting only 14% of the US population, but contributing to 30% of all fatal and nonfatal injuries due to MVCs and 35% ($25 billion) of the all medical and lost productivity costs. The current best-practice policy approach, Graduated Driver Licensing (GDL) programs, are effective primarily by delaying licensure and restricting crash opportunity. There is a critical need for interventions that target families to complement GDL...

BACKGROUND: Poor pelvic posture demonstrated through anterior pelvic tilt (APT) have been known to produce musculoskeletal imbalances involving weakness of the abdominal and pelvic musculature. While stretching and massage techniques have been reported to be effective in alleviating APT, it remains unclear if similar improvements can be elicited by posterior chain and core strength training. Therefore, the aim of this study was to examine the effect of an 8-week posterior and core strengthening program on APT, hamstrings-to-quadriceps (H:Q) strength ratio, and vertical jump performance in healthy individuals...

BACKGROUND: Mindfulness-based training programs have consistently shown efficacy in stress reduction. However, questions regarding the optimal duration and most effective delivery methods remain. OBJECTIVE: This research explores a 4-week neurofeedback-assisted mindfulness training for employees via a mobile app. The study's core query is whether incorporating neurofeedback can amplify the benefits on stress reduction and related metrics compared with conventional mindfulness training...

Benefiting from advances in few-shot learning techniques, their application to dense prediction tasks (e.g., segmentation) has also made great strides in the past few years. However, most existing few-shot segmentation (FSS) approaches follow a similar pipeline to that of few-shot classification, where some core components are directly exploited regardless of various properties between tasks. We note that such an ill-conceived framework introduces unnecessary information loss, which is clearly unacceptable given the already very limited training sample...

We have investigated the effects that partial-sleep-restriction (PSR0 , 4-h sleep retiring at 02:30 and waking at 06:30 h for two consecutive nights) have on 07:30 and 17:00 h cognitive and submaximal weightlifting; and whether this performance improves at 17:00 h following a 13:00 h powernap (0, 30 or 60-min). Fifteen resistance-trained males participated in this study. Prior to the experimental protocol, one repetition max (1RM) bench press and back squat, normative habitual sleep and food intake were recorded...

BACKGROUND: Contingency management (CM) is an evidence-based intervention for stimulant use and is highly effective in combination with medication for opioid use disorder. Yet, uptake of CM in opioid treatment programs that provide medication for opioid use disorder remains low. This paradox in which CM is one of the most effective interventions, yet one of the least available, represents one of the greatest research-to-practice gaps in the addiction health services field. Multi-level implementation strategies are needed to address barriers to CM implementation at both the provider- and organization-level...

BACKGROUND: Postpartum depression and anxiety are the 2 most common perinatal mental health disorders, with prevalence rates higher among women living in the Middle East than in most Western countries. The negative outcomes associated with postpartum depression and anxiety are profound and include less responsive parenting and compromised infant and young child development. Although interventions exist to prevent postpartum depression and anxiety, to date, there have been no studies that have attempted to prevent postpartum depression or anxiety among Arabic-speaking women in the Middle East, including Qatar...

BACKGROUND: Hyperthermia (and associated health and performance implications) can be a significant problem for athletes and teams involved in intermittent sports. Quantifying the highest thermal strain (i.e. peak core body temperature [peak Tc ]) from a range of intermittent sports would enhance our understanding of the thermal requirements of sport and assist in making informed decisions about training or match-day interventions to reduce thermally induced harm and/or performance decline...

PURPOSE: This study assessed the impact of different types of medial foot arch on postural stability and core center of gravity muscle activity among collegiate athletes. METHODS: The study sample included 103 university-level athletes across various sports (soccer, rugby, basketball, volleyball, field tennis, table tennis, karate, and cheerleading) from the College of Magdalena (Colombia) who exhibited distinct types of medial foot arch: 32 high, 35 low, and 36 neutral arches...

Inspired by the success of vision-language methods (VLMs) in zero-shot classification, recent works attempt to extend this line of work into object detection by leveraging the localization ability of pretrained VLMs and generating pseudolabels for unseen classes in a self-training manner. However, since the current VLMs are usually pretrained with aligning sentence embedding with global image embedding, the direct use of them lacks fine-grained alignment for object instances, which is the core of detection...

OBJECTIVE: The objective of this scoping review was to explore and synthesize the available literature on health research mentorship in low- and middle-income countries (LMICs). INTRODUCTION: Research mentorship is broadly considered a useful strategy to improve research capacities and research outputs. Existing literature and guidance on research mentorship have focused on high-income countries and assumed resource-rich environments. Despite the successful endeavors to improve health research capacity in LMICs, the strategies that work best under different circumstances are poorly understood...

Projected clustering is the foundation of deep clustering models. Aiming at catching the essence of deep clustering, we propose a novel projected clustering framework by summarizing the core properties of prevalent powerful models, especially deep models. At first, we introduce the aggregated mapping, consisting of projection learning and neighbor estimation, to obtain clustering-friendly representation. Importantly, we theoretically prove that the simple clustering-friendly representation learning may suffer from severe degeneration, which can be regarded as over-fitting...

BACKGROUND: Trust is essential for healthy, reciprocal relationships; creating safe environments; engaging in transparent interactions; successfully negotiating power differentials; supporting equity and putting trauma informed approaches into practice. Less is known, however, about the ways that trust-building may be at the forefront of consideration during community capacity building efforts, what trust-building elements are perceived as essential for optimally engaging communities, and what practices might support these efforts...

The purpose of this study was to scrutinize the interdependence among training quality, graduate demographic characteristics, and graduate competence and employability in the agro-food processing sub-sector of the TVET system in Ethiopia. To that effect, the commitment and competence of graduates and trainers, the quantitative and qualitative aspects of resource supplies, training and assessment practices including industry involvement or cooperative training, and the relationships with and influence of the human and material resources on graduate competence were examined...

BACKGROUND/OBJECTIVES: The influence of post-exercise cooling on recovery has gained much attention in the empirical literature, however, data is limited in regards to optimizing recovery from taekwondo performance when combat is repeated in quick succession within the same day. The aim of this study was therefore to compare the effects of external and internal cooling after simulated taekwondo combat upon intestinal temperature (Tint ), psychomotor skills (reaction time, response time, movement time), and neuromuscular function (peak torque, average power, time to reach peak torque)...

BACKGROUND: The long co-evolution of Homo sapiens and Plasmodium falciparum has resulted in the selection of numerous human genetic variants that confer an advantage against severe malaria and death. One such variant is the Dantu blood group antigen, which is associated with 74% protection against severe and complicated P. falciparum malaria infections in homozygous individuals, similar to that provided by the sickle haemoglobin allele (HbS). Recent in vitro studies suggest that Dantu exerts this protection by increasing the surface tension of red blood cells, thereby impeding the ability of P...

INTRODUCTION: Professional identity formation (PIF) is a foundational element to professional medical education and training. Given the impact of faculty role models and mentors to student and trainee learning, mapping the landscape of PIF among faculty takes on increased importance. We conducted a scoping review of PIF through the lens of situated learning theory. Our scoping review question was: How is situated learning theory used to understand the process of PIF among graduate medical educators? METHODS: The scoping review methodology described by Levac et al served as the architecture for this review...

Background: Small intestinal neuroendocrine tumors (SI-NETs) are the most common malignant tumors of the small intestine, with many patients presenting with metastases and their incidence increasing. We aimed to find effective diagnostic biomarkers for patients with primary and metastatic SI-NETs that could be applied for clinical diagnosis. Methods: We downloaded GSE65286 (training set) and GSE98894 (test set) from the GEO database and performed differential gene expression analysis to obtain differentially expressed genes (DEGs) and differentially expressed long non-coding RNAs (DElncRNAs)...
