Sleep & Nutrition for Athletes

Abstract Sleep is vital for the maintenance of physical and mental health, recovery and performance in athletes. Sleep also has a restorative effect on the immune system and the endocrine system. Sleep must be of adequate duration, timing, and quality to promote recovery following training and competition. Inadequate sleep adversely impacts carbohydrate metabolism, appetite, energy intake and protein synthesis affecting recovery from the energy demands of daily living and training/competition related fatigue. Sleep’s role in overall health and wellbeing has been established. Athletes have high sleep needs and are particularly vulnerable to sleep difficulties due to high training and competition demands, as such the implementation of the potential nutritional interventions to improve sleep duration and quality is commonplace. The use of certain nutrition strategies and supplements has an evidence base i.e. carbohydrate, caffeine, creatine, kiwifruit, magnesium, meal make-up and timing, protein and tart cherry. However, further research involving both foods and supplements is necessary to clarify the interactions between nutrition and the circadian system as there is potential to improve sleep and recovery. Additional research is necessary to clarify guidelines and develop products and protocols for foods and supplements to benefit athlete health, performance and/or recovery. The purpose of this review is to highlight the potential interaction between sleep and nutrition for athletes, and how these interactions might benefit sleep and/or recovery.

Network based evidence of suicidal ideation among teachers.

This study investigates the relationship between risk and protective factors and suicidal ideation among teachers, a group often overlooked in suicide prevention efforts. Using the diathesis-stress model as a partial framework, the research explores how depression and anxiety, as risk factors, and emotional intelligence, resilience, and positive thoughts, as protective factors, influence suicidal ideation. A cross-sectional design was employed, involving 1,270 Spanish teachers (median age: 46, 70.2% female). Key measures included the Positive and Negative Suicidal Ideation scale (PANSI), the Brief Emotional Intelligence Scale (BEIS-10), the Brief Resilient Coping Scale (BRCS) for resilience, and the General Health Questionnaire (GHQ-12) for depression and anxiety. A network approach was used to examine the relationships between these variables. Results showed that depression had a stronger relationship with negative ideation than anxiety, while emotional intelligence and positive thoughts acted as protective factors. Positive ideation was negatively associated with depression and anxiety, and positively linked to emotional intelligence and resilience. Emotional intelligence emerged as the most critical protective factor. These findings provide valuable evidence to inform the development of emotional management and resilience-building programs aimed at enhancing teachers' mental health and performance, which could also indirectly benefit students.

How 808 bass affect people's mental performance

This article delves into the "rage music" trend led by Trippie Redd through his song "Miss the Rage" in 2021, particularly focusing on the psychological implications of the pivotal 808 bass drum within this genre. Originating from the Roland TR-808 drum machine, the 808 bass, with its deep and prolonged tone, has become an iconic element in hip-hop music, eliciting potent psychological and physiological responses from listeners. Research indicates that the 808 bass not only stimulates emotional arousal and excitement due to its unique sonic characteristics but may also trigger aggressive behavior as a result of its long-term association with provocative content. While this connection necessitates substantial repetition to establish, the widespread dissemination of hip-hop music has significantly manifested the provocative effect of the 808 bass within specific demographics. Furthermore, the high volume and multimodal perception of the 808 bass during mental performance contribute to the aggressive behavior of audiences. Nevertheless, the study acknowledges that the direct link between the 808 bass and mental performance requires further investigation, taking into account factors such as cultural backgrounds and listening environments.

The impact of imagery training on achievement motivation among young swimmers aged 10-15 years

Achievement motivation is a critical factor in the performance and development of young athletes. It drives them to set and pursue goals, overcome obstacles, and succeed in sports. Understanding and enhancing achievement motivation can significantly impact young athletes' progress and performance. This study aims to examine the effect of imagery training on the achievement motivation of young swimmers to achieve, especially in commitment, goal setting, self-confidence, and engagement. The research design uses one group pre-test and post-test. A sample of 20 young swimmers participated in the study. Achievement motivation was assessed using standardized pre-test and post-test measures. The independent sample t-test revealed a highly significant difference between pre-test and post-test means (t = -26.937, p = 0.000), confirming the effectiveness of imagery training. These improvements suggest that imagery training can improve swimmers' commitment, goal-setting ability, self-confidence, and engagement in training. Although this study has several limitations, such as limited sample size and short training duration, the results confirm the importance of imagery training as an effective method in supporting mental development and performance improvement in young swimmers. Further research is recommended to address these limitations and explore the long-term effects of imagery training.

Safety and Efficacy of Ashwagandha Root Extract on Cognition, Energy and Mood Problems in Adults: Prospective, Randomized, Placebo-Controlled Study.

This prospective, randomized, placebo-controlled study assessed the effects of Ashwagandha root extract (ARE) on cognition, energy, and mood in adults with self-reported cognitive and energy problems. Healthy subjects aged 30-75 years were randomized to receive ashwagandha (Withania somnifera) root extract (ARE) 600 mg/day (n = 60)/identical placebo (n = 60) orally for 8 weeks. Cognitive function was assessed at baseline and week 8 using a Computerized Mental Performance Assessment System (COMPASS). Secondary outcomes were Profile of Mood States Abbreviated Version (POMS-A), Mental Fatigue Scale (MFS) and Behavior Rating Inventory of Executive Function-Adult (BRIEF-A) for effects on mood, mental fatigue and executive function, respectively, assessed at baseline, week 4 and 8. Greater improvement (p < .05) from baseline scores were seen with ARE as against placebo for COMPASS items episodic memory, working memory and accuracy of attention. ARE also improved the POMS-A, MFS and BRIEF-A scores from baseline suggesting an improvement in mood, vigor, and an increase in the executive functioning respectively with ARE. The herb was well tolerated and had a good patient compliance with no serious adverse events reported in either of the groups. This study suggests that a dose of 600 mg a day can improve cognition, energy, and mood in adults with self-reported cognitive and energy problems.

Indoor Air Quality in Laboratories and Its Relationship with Psychological Performance Among University Students in Malaysia

Introduction: Poor indoor air quality (IAQ) in work environments can reduce productivity and decrease overall performance. This study examines IAQ in university laboratories and its relationship with psychological performance among students in Malaysia. Methods: This cross-sectional study was conducted from October to November 2023 in six laboratories at a Malaysian university, categorised into chemical and non-chemical. A total of 117 students aged 18 to 40 participated. IAQ was measured in real-time for 8 hours during weekdays using instruments for particulate matter (PM2.5, PM10), carbon monoxide (CO), total volatile organic compounds (TVOC), airborne microorganisms, carbon dioxide (CO2), temperature in °C, relative humidity (RH), and air movement. Psychological performance was assessed using the General Health Questionnaire (GHQ-12) and Post Occupancy Evaluation (POE). Data analysis was performed using Kruskal-Wallis, One-Way ANOVA, and Chi-Square tests. Results and Discussion: Significant differences in IAQ parameters were observed for PM2.5 (p=0.007), PM10 (p=0.020), CO2 (p=0.024) and RH (p=0.043). Psychological distress affected 41.9% of students based on the predefined threshold. High CO levels (≥0.67 ppm) and elevated temperatures (≥23.28°C) were significantly associated with increased psychological distress (p=0.011). Students exposed to these conditions were 1.3 times more likely to experience distress (OR=1.3). Conclusion: Specific IAQ parameters, particularly CO and temperature, critically impact students’ psychological well-being. Improving IAQ by reducing CO levels and maintaining optimal temperatures may enhance mental health and performance. Improving IAQ by reducing CO levels and maintaining optimal temperatures may enhance mental health and performance. However, external factors such as personal stressors could not be entirely controlled.

Pharmacodynamics of Drugs Adaptation to Activity in Extreme Conditions

Information is provided on the results of new exploratory pharmacological studies for the treatment of anxiety disorders, depression, post-traumatic stress disorders, aimed at regulating the central mechanisms that determine the development of distress and emerging pathologies.

Perceptions of Cognitive Load and Workload in Nurse Handoffs: A Comparative Study Across Differing Patient-Nurse Ratios and Acuity Levels.

Medical errors, often resulting from miscommunication and cognitive lapses during handoffs, account for numerous preventable deaths and patient harm annually. This research examined nurses' perceived workload and cognitive load during handoffs on hospital units with varying patient acuity levels and patient-nurse ratios. Conducted at a southeastern US medical facility, the study analyzed 20 handoff dyads using the National Aeronautics and Space Administration Task Load Index to measure perceived workload and cognitive load. Linear regressions revealed significant associations between patient acuity levels, patient-nurse ratios, and National Aeronautics and Space Administration Task Load Index subscales, specifically mental demand (P = .007) and performance (P = .008). Fisher exact test and Wilcoxon rank sum test showed no significant associations between these factors and nurses' roles (P > .05). The findings highlight the need for targeted interventions to manage workload and cognitive load, emphasizing standardized handoff protocols and technological aids. The study underscores the variability in perceived workload and cognitive load among nurses across different units. Medical-surgical units showed higher cognitive load, indicating the need for improved workload management strategies. Despite limitations, including the single-center design and small sample size, the study provides valuable insights for enhancing handoff communications and reducing medical errors.

Investigation of the playing digital games on shoulder flexibility, muscle strength and reaction speed in volleyball players

Esports is a natural extension of digital games. Digital games provide a platform for players to showcase their skills, thereby forming the foundation of e-sports. These two domains continuously support each other, demonstrating significant growth in popularity and establishing a solid presence in the competitive landscape. Digital games require high levels of attention, strategy, reflexes, and coordination, offering pathways to reach the pinnacle of competition. The benefits derived from digital games enhance the ability to perform effectively under stress, making them crucial for both physical and mental performance. This study investigates the effects of digital gaming on the physical performance, shoulder flexibility, muscle strength and reaction speed of female volleyball players. A total of 50 female volleyball players took part, who were divided into two groups based on their digital playing habits: Group 1 consisted of female players who played video games for at least 4 h per day in the last 6 months, while Group 2 included those who played &amp;lt;4 h per day. In the study, the Activ5© Handheld Digital Dynamometer was used to measure the strength of the shoulder muscles during various movements, including flexion, hyperextension, abduction, internal rotation and external rotation. In addition, the BlazePod™ trainer device was used to assess reaction times. The results showed that volleyball players who frequently played digitally showed significant improvements in shoulder flexibility, especially in flexion of the non-dominant side. In addition, these players showed faster reaction times than those who played less frequently. However, a significant decrease in hyperextension muscle strength was observed in the group that frequently played digital games. The study highlights that while digital games can improve certain physical skills such as reaction speed and shoulder flexibility, they can also contribute to muscular imbalances or a decrease in muscle strength in certain areas. These findings suggest potential benefits for volleyball players, particularly in movements that require quick reflexes and flexibility, such as serving and spiking. However, the results also raise concerns about potential negative effects on muscle strength and posture, highlighting the need for balanced training programs to mitigate these effects. Further research is needed to investigate the long-term effects of digital games on athletic performance and physical health.

Axial rotation affects the cognitive characteristics of spatial ability.

To test spatial ability in athletes with different axial rotation experience and analyze their behavioral data to explain the cognitive mechanisms of spatial ability in athletes. Experiment 1: A total of 147 athletes were selected for the paper-and-pencil mental rotation test (MRT). The athletes were separated according to three sport types: open high-spatial (OH) sport, closed high-spatial (CH) sport, closed low-spatial (CL) sport. Spatial ability testing with a two-factor mixed experimental design of 3 (sport type) × 2 (stimulus type). Experiment 2: In this study, 47 players were selected for computerized mental rotation test, with a three-factor mixed experimental design of 3 (sport type) × 2 (angle: 45°, 90°) × 3 (rotational axis: left-right axis, up-down axis, and front-back axis). Repeated-measures ANOVA was performed to evaluate the data. (1) The CH group and OH group outperformed the CL group in the non-embodied task (all ps < 0.003) and the CH group was better than the other groups in the embodied and tasks (all ps < 0.008). (2) Under 45° rotational conditions, the reaction time (RT) for the left-right (LR) and up-down (UD) axes were shorter than that for the front-back (FB) axis (all ps < 0.026). However, under 90° conditions, the RT for FB < LR < UD, with superior accuracy and rotational speed for the FB axis than for the LR and UD axes (all ps < 0.034). (3) Male players from the CH and CL groups had shorter RTs than did those from the OH group at both angles (all ps < 0.047). For female players, the CH group presented a shorter RT than the OH and CL groups did at 90° (all ps < 0.006). (4) No sex difference was found for paper and pencil MRTs, but a male advantage existed only in the CL group for computerized MRTs (p = 0.005). The motor skills associated with axial rotation could promote mental rotation performance and compensate for sex differences in mental rotation ability.

The Effect of Self-Monitoring on Mental Effort and Problem-Solving Performance: A Mixed-Methods Study

Self-regulated learning (SRL) has become increasingly important for learners in the 21st century as they engage more frequently in student-centered education. Accurate self-monitoring of one’s learning process is central to SRL. However, research has shown that learners often struggle with monitoring accuracy. One possible explanation is that the process of self-monitoring itself may add cognitive load, potentially reducing both self-monitoring accuracy and overall performance. In the current study, we investigated the effects of self-monitoring on perceived mental effort and performance during problem-solving tasks of increasing complexity. Participants in the experimental condition were instructed to think aloud while problem-solving, while those in the control condition did not receive such instructions. Our findings indicate no interaction effect between the requirement for explicit and continuous self-monitoring and task complexity on perceived mental effort and performance. However, task complexity significantly impacted the perceived mental effort and performance in both conditions, while it affected monitoring accuracy exclusively in the experimental condition. Furthermore, qualitative analyses showed that the participants in the experimental conditions engaged in self-monitoring during 21.2 % of their think-aloud protocols. Contrary to previous research, self-monitoring did not appear to increase cognitive load, although the experimental participants took significantly longer to complete all the tasks. Possible explanations for these findings are discussed.

National Collegiate Athletic Association Athletic Trainers’, Head Coaches’, and Student-Athletes’ Perceptions of Professional Titles Used in Sport PsychologyA

The purpose of this convergent mixed-methods study was to explore National Collegiate Athletic Association (NCAA) Division I athletic trainer (AT), head coach, and student-athlete perceptions of three commonly used sport psychology professional titles in the United States: Certified Mental Performance Consultant (CMPC), mental conditioning coach, and sport psychologist. Participants included 73 ATs, 79 head coaches, and 76 student-athletes. Participants completed an online questionnaire that assessed their previous exposure to these professionals, the services they believed these professionals could provide, their confidence in sport psychology consultation from these professionals, and their stigma tolerance of these professionals. A series of Friedman tests found that ATs and student-athletes perceived significantly more confidence in the services of a sport psychologist compared to a CMPC and a mental conditioning coach. A series of Kruskal-Wallis tests revealed that student-athletes perceived significantly more stigma in using services from all three professionals than head coaches and ATs. Participants reported that sport psychologists could provide mental performance and mental health services, while CMPCs and mental conditioning coaches primarily provided mental performance services. However, short answer responses from many ATs and head coaches about CMPCs demonstrated some doubt and misunderstanding of this professional title.

BackgroundBurnout is a proven challenge in surgeons and surgical trainees, associated with higher rates of attrition compared to other medical specialties. Here we report the impact of a mental performance coaching program as it relates to surgery trainee wellbeing. MethodsA mixed-format mental performance coaching program was implemented at a large academic medical center's general surgery residency over a single academic year. Survey scores related to burnout, self-efficacy, and professional fulfillment were used to analyze the impact of the program as a whole, as well as by large group, small group, and one-on-one format attendance. ResultsResidents that attended the small group or one-on-one sessions demonstrated a trend towards improved burnout and professional fulfillment. The PGY3 group attended the most small format sessions and demonstrated a significant decrease in burnout (p ​= ​0.03). ConclusionThis offers an adaptable intervention for residency programs to improve the wellbeing of their trainees.

Enhancing Cognitive Fit: Exploring the Potential of Mixed Reality for Developing Mental Rotation Skills

Mixed Reality is a promising venue for spatial ability training, allowing participants to engage in problem-solving through gesture-based interactions with holographic objects. 3-D measurement of learning in Mixed Reality environments may result in a better cognitive fit than 2-D. This mixed-method study measures and enhances mental rotation ability and investigates user experience in Mixed Reality. To assess mental rotation ability, we adapted the Purdue Spatial Visualization Test:Rotation for Microsoft HoloLens 2, creating a measurement tool for our Mixed Reality-based training program, Holomental. Comparing 2-D and 3-D tests, we explored how stimulus dimensionality influences accuracy and cognitive load. Our findings indicate that Holomental enhances mental rotation performance, both in 2-D and 3-D. Cognitive load in the 3-D test was lower than in the 2-D test. Semi-structured interviews revealed participants’ appreciation for the representational and interactional affordances of the training environment. This study provides valuable insights into the effectiveness of 3-D spatial training, with implications and suggestions for future design considerations.

Health impact of environmental and industrial noise - a narrative review.

Industrial noise sources are among the environmental noise sources that are ranked second among the causes of ill health in Europe by the World Health Organization. The aim of this paper is to summarize and review of published information focusing on noise annoyance from industrial activities and mining. A search for articles was performed using the bibliographic databases platforms. The epidemiological evidence shows that environmental noise may be associated with cardiovascular and metabolic diseases, impaired cognitive development in children, mental health, post-irritability, and sleep disturbances. As a result of efforts to minimize the effects of industrial noise on human health, the New South Wales Environment Protection Authority published A Guide to the Noise Policy for Industry in 2017, which sets out recommended noise levels, methods, and procedures for noise management based on the latest scientific evidence. Social networks can be used to assess the population's noise annoyance and to verify the effectiveness of the measures. The industrial noise sources are typically defined by low-frequency noise. Low-frequency noise has very low attenuation and is only slightly affected by obstacles, therefore it can be a major cause of night noise annoyance. An association was confirmed between exposure to low-frequency noise and sleep disturbance, psychological problems, cognitive impairment, increased social conflicts, anxiety, emotional instability, nervousness, and reduced mental performance - concentration, and visual perception. In view of the long tradition of mining and industry, the assessment of noise from these activities from the perspective of its impacts on human health is an inherent part of legislative processes.

Post-Lunch Napping as a Strategy to Enhance Physiological Performance and Cognitive Function in Elite Volleyball Players

Background and Objectives: Volleyball demands high levels of anaerobic strength, flexibility, agility, and mental focus. Adequate sleep has been shown to enhance athletic performance and cognitive function. This study investigates the impact of post-lunch naps of varying durations (25 and 45 min) on the physiological performance and cognitive focus of elite volleyball players. Materials and Methods: Sixteen elite volleyball players (8 male, 8 female) with at least 7 years of competitive experience participated in a randomized crossover study. They underwent three experimental conditions: no nap (No-Nap), a 25-min nap (N25), and a 45-min nap (N45). Physical performance was measured through counter-movement jumps (CMJ) and volleyball agility tests, while cognitive function was assessed using the D2 attention test. Statistical analysis included repeated measures ANOVA to examine the differences between nap conditions and gender-specific responses. Results: Significant improvements in both physical performance and cognitive focus were observed in the N25 and N45 conditions compared to the No-Nap condition (indicating the effectiveness of short naps in enhancing both physical and mental performance). Males outperformed females in most physical metrics, while females scored higher on the D2 attention test (suggesting possible gender-specific responses to napping). The 25-min nap showed slightly better results in terms of sleep quality and subsequent performance (confirming that shorter naps may be more beneficial). Conclusions: Post-lunch naps, especially of 25 or 45 min, enhance both physiological and cognitive performance in elite volleyball players. These findings suggest that integrating short naps into athletes’ training regimens can improve performance and focus, with potential gender-specific benefits. Further research is needed to explore long-term effects and variations across other sports.

Impact of obesity on allergic respiratory diseases and on mental and cognitive performance

Summary Background Obesity and allergies are among the most common diseases of our civilization. Given the simultaneous rise in the prevalence of these diseases in recent years, a potential causal link between the two has been proposed. In particular, obese patients are at an increased risk of developing bronchial asthma, likely due to mechanical restrictions but also to metabolic changes that adversely affect immune function. Neuroscience studies have also shown that obesity can lead to impaired brain function and mental health. In the following review, we will take a closer look at our studies that focus on the influence of obesity on allergic diseases and cognitive performance. Results Both human studies and animal models (mice) have shown that obesity leads to increased allergic responses in the airways. Our studies in a mouse model of obesity confirm that an obese phenotype is associated with increased allergic sensitization and manifestation. These changes are associated with significant shifts in the composition of the gut microbial flora. The microbiome changes are further associated with allergic airway inflammation and an increased incidence of T helper 1 (Th1) type pulmonary macrophages. Interestingly, despite the changes in the microbiome, it is possible to effectively prevent allergy development by inducing oral tolerance. Furthermore, it was observed that obese mice show increased signs of anxiety and depression, as well as reduced cognitive performance. Conclusion Obesity is a complex metabolic disease that significantly impacts our body’s gut microbiome and immune system, resulting in an increased incidence of allergic asthma and neurological/psychological changes. Attention should be given to both the prophylactic and therapeutic measures to mitigate the impact of obesity, including oral tolerance for managing existing allergic diseases.

Differential impacts of high and low-intensity physical exercise on brain wave activity and functional connectivity in professional athletes: a systematic review

Introduction: This systematic review explores the differential impacts of high and low-intensity physical exercise on brain wave activity and functional connectivity in professional athletes. The study aims to elucidate how varying exercise intensities influence cognitive and emotional responses, brain connectivity, and overall mental health. Additionally, it examines the potential synergistic effects of integrating neurofeedback training with physical exercise. Method: A comprehensive literature search was conducted using databases such as PubMed, Scopus, and Google Scholar. Keywords included "high-intensity exercise," "low-intensity exercise," "brain wave activity," "functional connectivity," "professional athletes," and "cognitive performance." Inclusion criteria were studies published in peer-reviewed journals involving professional athletes and examining the impact of exercise intensity on brain wave activity and functional connectivity. Data extraction focused on study design, sample size, exercise intensity, neuroimaging techniques, brain wave activity, and functional connectivity outcomes. Results: High-intensity physical exercise was found to induce significant changes in functional connectivity within affect and reward networks, enhance mood, and improve cognitive performance through increased brain wave coherence and synchronization. Low-intensity exercise primarily enhanced cognitive and attentional processing by increasing resting-state functional connectivity in the fronto-parietal network. Neurofeedback training was shown to enhance brain wave activity, reduce stress levels, and increase self-control over physiological factors. The combined approach of neurofeedback and physical exercise demonstrated potential for optimizing both mental and physical performance in athletes. Conclusion: The findings indicate that high-intensity exercise leads to significant and prolonged changes in brain connectivity and cognitive performance, while low-intensity exercise benefits cognitive and attentional processing. The discussion introduces the Neurofeedback and Physical Fitness Synergy Theory, which posits that integrating neurofeedback with physical exercise can lead to optimal improvements in both physical fitness and mental health. This combined approach suggests a promising strategy for enhancing overall athletic performance and mental well-being. Future research should focus on standardized measures and long-term studies to further validate these findings and explore the underlying neurophysiological mechanisms.
