Co-Designing Dynamic Mixed Reality Drill Positioning Widgets: A Collaborative Approach with Dentists in a Realistic Setup.

Mixed Reality (MR) is proven in the literature to support precise spatial dental drill positioning by superimposing 3D widgets. Despite this, the related knowledge about widget's visual design and interactive user feedback is still limited. Therefore, this study is contributed to by co-designed MR drill tool positioning widgets with two expert dentists and three MR experts. The results of co-design are two static widgets (SWs): a simple entry point, a target axis, and two dynamic widgets (DWs), variants of dynamic error visualization with and without a target axis (DWTA and DWEP). We evaluated the co-designed widgets in a virtual reality simulation supported by a realistic setup with a tracked phantom patient, a virtual magnifying loupe, and a dentist's foot pedal. The user study involved 35 dentists with various backgrounds and years of experience. The findings demonstrated significant results; DWs outperform SWs in positional and rotational precision, especially with younger generations and subjects with gaming experiences. The user preference remains for DWs (19) instead of SWs (16). However, findings indicated that the precision positively correlates with the time trade-off. The post-experience questionnaire (NASA-TLX) showed that DWs increase mental and physical demand, effort, and frustration more than SWs. Comparisons between DWEP and DWTA show that the DW's complexity level influences time, physical and mental demands. The DWs are extensible to diverse medical and industrial scenarios that demand precision.

THE IMPACT OF USING SMART WATCHES ON STUDENTS’ EFFORT CAPACITY: A COMPARATIVE STUDY

The increasing use of smartwatch technology among university students has raised questions about its potential impact on physical health and effort capacity. This study aims to evaluate the influence of smartwatch usage on the physical performance and effort capacity of students, focusing on those who utilize these devices for monitoring physical activity and health functions. In this comparative study, we employed a questionnaire to assess the adoption and usage patterns of smartwatches among students. The research sample was divided into two groups: a control group and an experimental group. Both groups participated in weekly aerobic gymnastics classes. However, the experimental group, equipped with smartwatches, was tasked with achieving a daily goal of 13,000-15,000 steps or expending 600 kcal. At the conclusion of the experiment, we evaluated the exercise capacity of all students using the Ruffier and Harvard tests. The results revealed significant differences between the two groups, with the experimental group demonstrating notably higher effort capacity. This suggests that the regular use of smartwatches, combined with specific fitness targets, can enhance physical performance and overall health among students. Our findings underscore the potential benefits of integrating wearable technology into student lifestyles, particularly in promoting physical activity and improving exercise capacity. This study contributes to the growing body of literature on the impact of smartwatches on health and fitness, highlighting their role as valuable tools for monitoring and enhancing physical performance in an academic setting. In conclusion, smartwatches can be useful tools for students, but they must be used with discernment. It is important to strike a balance between the benefits and distractions these devices bring. Students' effort capacity may be influenced by how they integrate smartwatches into their daily routine.

COMPREHENSIVE INJURY PREVENTION STRATEGIES FOR FOOTBALL PLAYERS

Injury prevention in football is a critical issue for athletes, coaches, and health professionals, given the sport's dynamic movements that elevate the risk of muscle and joint injuries. Effective strategies should incorporate specialized physical training and physiotherapeutic interventions to optimize player protection and performance. Preventive training programs, emphasizing muscle strengthening and proprioception, are essential for reducing injury risks. Specific exercises targeting the hamstrings, quadriceps, calves, and core enhance joint stability and mitigate overload injuries. Neuromuscular training, which includes balance exercises and plyometrics, improves proprioception and helps prevent falls and twists. Flexibility through regular stretching and dynamic warm-ups, such as the FIFA 11+, is crucial for preparing players physically and lowering injury incidence. Additionally, physiotherapists play a vital role in injury prevention through functional assessments to identify muscle imbalances and develop corrective exercise programs. Manual therapy techniques, joint stabilization exercises, and preventive rehabilitation further contribute to maintaining soft tissue quality and preventing muscle strains. Monitoring training load is another fundamental aspect of injury prevention, as abrupt changes in training intensity can lead to injuries. Using tracking technologies allows for better control of players' physical efforts. Studies indicate that implementing structured injury prevention programs significantly reduces injury rates and enhances athletic performance. Research highlights the importance of a multicomponent approach, individualized training, and load management to lower hamstring injuries. Collaboration among athletes, coaches, and health professionals is crucial to create a safe training environment. As football evolves, prioritizing injury prevention is essential for players' health, success, and career longevity.

Development and validation of a French job-exposure matrix for healthcare workers: JEM Soignances.

This study aimed to develop and evaluate a job-exposure matrix (JEM) specific to healthcare workers, JEM Soignances, based on self-reported data. The JEM was constructed using data from healthcare workers within the CONSTANCES cohort (N=12 489). Job titles and sectors of activity (eg, hospital activities) defined occupational groups. We assessed 24 exposures covering organizational, psychosocial, physical, chemical and biological factors. Several methods (group-based frequency, CART, random forest, extreme gradient boosting machine) were applied using a 70% training sample. Performance was evaluated on the remaining 30% using area under the ROC curve (AUC) and Cohen's Kappa (κ). Two alternative JEM were proposed using only job titles or adding healthcare establishment size and type (public/private) to define occupational groups. All methods offered similar discriminatory power (AUC). We selected the group-based frequency method as it was the most understandable and easiest to implement. Of the 24 included exposures, 15 demonstrated satisfactory performance, with nine showing good discriminatory power and fair-to-moderate agreement, such as physical effort at work (AUC=0.861, κ=0.556), ionizing radiation exposure (AUC=0.865, κ=0.457), carrying heavy loads (AUC=0.840, κ=0.402), shift work (AUC=0.807, κ=0.383), and formaldehyde exposure (AUC=0.847, κ=0.289). The remaining nine exposures mainly showed poor-to-moderate discriminatory power and poor agreement. Compared to JEM Soignances, the job title-only JEM performed poorly, while the one incorporating healthcare establishment size and type showed similar results. JEM Soignances provides good internal performance and validity. Future research will assess its external validity by comparing it with existing JEM and examining its predictive validity regarding known associations between exposures and health outcomes (eg, long working hours and strokes).

Youth soccer team’s match dynamics with and without the ball when in both conditions of advantage and disadvantage

ABSTRACT The aim of this study was twofold: i) to compare the collective organisation and running performance with and without the ball, in conditions of advantage and disadvantage; ii) characterise and analyse the methods of attack and defence prevalent in the team during these conditions. Considering two play-off matches of a youth team, 150 actions with and 166 without the ball it was analysed. The dependent variables were captured by GPS devices, while the attack/defence method prioritised by the team was identified through notational analysis. The team prioritised positional attack and mixed defence at a disadvantage, and direct attack and zone defence at an advantage in the clashes. With the ball and at a disadvantage, the team occupied a greater surface area and width, covered a greater distance at low intensity and displayed more accelerations. Without the ball and at a disadvantage, the team also occupied a greater surface area, in width and length, remaining less compacted. The team also showed less physical effort at a disadvantage. We conclude that the team differed in collective organisation, method of attack and defence and running performance both with and without the ball, considering whether it had an advantage in the clashes.

The impact of AAOCA anatomical characteristics in coronary blood supply

Abstract Background Impact of AAOCA in coronary blood flow and myocardial perfusion is an unknown field although it is well-accepted that the anomaly is one of the leading causes of sudden death during effort. The risk factors for AAOCA are the anatomical characteristics of the abnormal vessel, such as the presence of intramural (IM) segment, the ostium shape, and the take-off angle. Purpose We aim to evaluate the impact of AAOCA anatomical risk profile in the blood flow using the thermodilution technique, an accurate and reproducible method used to investigate coronary physiology. Methods This is a single-centre prospective study that included AAOCA subjects who underwent invasive thermodilution functional coronary assessment. We divided patients into two groups according to the anatomical risk profile: a) ischemic risk (IR): concomitant presence of IM segment, take-off angle<45°, and slit-like/oval shape ostium, or a IM length>10 mm; b) no-ischemic risk (no-IR): absence of IM segment, take-off angle>45°, round ostium. We obtained coronary functional measures using the thermodilution method. We measured the absolute flow, and coronary resistance at rest and maximal hyperemia. Data were reported as median and IQR and we used Wilcoxon signed-rank test for paired data in the rest vs. hyperaemia comparison. Results We included 28 AAOCA pts (22 male, 6 female, median age: 48.6 (IQR: 18.9) ) that were 20 anomalies of the right coronary and 8 of the left. Symptomatic subjects (n=16) presented with angina (n=12), syncope (n=1), presyncope (n=1), fatigue (n=1), and dyspnea associated with arrhythmia (n=1). The IR group (26 pts; R-AAOCA=24, L-AAOCA=2) has an IM segment with a median length of 10 mm (IQR: 5.5), a median take-off angle of 28° and the ostium was slit-like (n=16), oval (n=10), and round (n=1). The no-IR group consisted of 9 (R-AAOCA=3, L-AAOCA=6), median take-off angle of 69° and the ostium was oval (n=1), and round (n=8). The absolute flow and coronary resistance at rest of the IR group did not have significant differences compared to no-IR. Hyperemia determines an increment of coronary flow in both groups although the IR had a 2.9 fold increase and the no-IR as 3.5 fold increase compared to rest. In particular, the absolute flow of the IR group was significantly lower compared to the no-IR group (185 vs. 330 mL/min, p=0.012) and there was a greater coronary resistance (419 vs. 268 mmHg/(mL/min), p=0.027), as shown in Fig. 1. Conclusions Anatomical risk factors of AAOCA, such as IM take-off angle and ostium morphology, have a negative impact on the coronary blood supply that is reduced when compared to AAOCA without such anatomical features. Such impact can be revealed also at rest using the thermodilution method that induces maximal coronary vasodilatation that is the natural coronary response to physical effort. Further studies are needed to validate benefit of functional assessment in AAOCA risk stratification.

Validation of the CRAVE-C scale in Chinese adults: a four-study examination of competing motivations for physical activity versus rest.

The study aimed to validate the Cravings for Rest and Volitional Energy Expenditure (CRAVE) scale among Chinese adults with different health conditions (healthy control, chronic illnesses, and psychiatric disorders) and skill levels (athletes vs. non-athletes). In Study 1, a confirmatory factor analysis (CFA) using the Maximum Likelihood Method (MLM) was performed on a Chinese sample of emerging adults (N = 481) to evaluate the structural validity of the Cravings for Rest and Volitional Energy Expenditure-Chinese version (CRAVE-C). In Study 2, differences in "Move" and "Rest" desires were examined among patients with psychiatric disorders, patients with chronic illnesses, and healthy controls. In study 3, investigated the relationship between cardiorespiratory fitness and exercise motivation using the CRAVE-C (N = 83). In Study 4, the changes in "Move" desire from baseline to post-training were compared between athletes and non-athletes. Results from Study 1 indicated that the 10-item CRAVE-C showed good fit indices ( Chi2 (34) = 118.769, CFI = 0.95, TLI = 0.934, SRMR = 0.053, RMSEA = 0.072). "Move" positively correlated with various factors of the Affective Exercise Experiences Questionnaire-Chinese and the Physical Effort Scale-Chinese, while "Rest" correlated negatively. In Study 2, Patients with psychiatric disorders had a significantly higher "Move" desire than healthy controls. Patients with chronic illnesses had a significantly higher "Rest" desire than healthy controls. In Study 3, higher cardiorespiratory fitness was associated with a slight increase in "Move" desire (3.26% ± 37.35%) and a decrease in "Rest" desire (18.94% ± 66.99%). Lower fitness was linked to a significant decline in "Move" desire (-54.61% ± 111.33%) and an increase in "Rest" desire (43.62% ± 63.64%). In Study 4, the athlete group demonstrated a significant increase in "Move" desire from baseline to post-training, whereas the non-athlete group reported a significant decrease in "Move" desire from baseline to post-training. The 10-item CRAVE-C has good reliability and validity in the Chinese cultural context and can be used among Chinese adults with different health conditions and skill levels.

Adolescents’ physical activity during and beyond the Covid-19 pandemic: a qualitative study exploring the experiences of young people living in the context of socioeconomic deprivation

BackgroundAdolescent physical activity levels are low and are shown to decline with age into adulthood. Emerging literature suggests these trends were exacerbated during the Covid-19 pandemic. We aimed to understand, from the perspective of adolescents living in deprived communities, whether the Covid-19 pandemic influenced their physical behaviour and explore their ideas for physical activity promotion moving forward.MethodsPurposive sampling was used to recruit older adolescents (13-18-year-old) living in one of the 20% most deprived areas in the UK, as defined by the UK Index of Multiple Deprivation. A mix of in-person and online one-to-one semi-structured interviews were conducted between July 2021- March 2022. Interviews were audio-recorded, transcribed verbatim and anonymised. Data were imported into Nvivo software and analysed drawing on Braun and Clarke’s six phases of thematic analysis.ResultsThe sample consisted of 16 adolescents and included a mix of genders. The following themes were generated during the data analysis: (1) Physical activity behaviour in everyday life (prepandemic), (2) The impact of Covid-19 on physical activity (during) and (3) Young people’s ideas about physical activity promotion (moving forward). Participants described themselves as inactive, with their activity limited to active travel, informal activity and physical education. Experiences of the pandemic were largely negative, impacting participants’ physical and mental health. Ideas around physical activity promotion ranged from the individual to the societal level.ConclusionsOur findings suggest the Covid-19 pandemic had a major impact on young people living in the context of socioeconomic deprivation. Physical activity promotion efforts should focus on school-based opportunities and the provision of safe and low-cost opportunities in socioeconomically deprived areas. As we aim to build back from the Covid-19 pandemic, supporting young people living in socioeconomically deprived communities should be prioritised.

Are caffeine effects equivalent between different modes of administration: the acute effects of 3 mg.kg-1 caffeine on the muscular strength and power of male university Rugby Union players.

There is growing interest in the potential of alternative modes of caffeine administration for enhancing sports performance. Given that alternative modes may evoke improved physical performance via distinct mechanisms, effects may not be comparable and studies directly comparing the erogenicity of alternative modes of caffeine administration are lacking. To address this knowledge gap, the present study evaluated the effect of 3 mg·kg-1 caffeine delivered in anhydrous form via capsule ingestion, chewing gum or mouth rinsing on measures of muscular strength, power, and strength endurance in male Rugby Union players. Twenty-seven participants completed the study (Mean ± SD: Age 20 ± 2 yrs; daily caffeine consumption 188 ± 88 mg). Following assessments and reassessment of chest press (CP), shoulder press (SP), Deadlift (DL), and Squat (SQ) 1-repetition maximum (1RM) and familiarization to the experimental procedures, participants completed six experimental trials where they were administered 3 mg.kg-1 caffeine (Caff) or placebo (Plac) capsule(CAP), chewing gum(GUM) or mouth rinse(RINSE) in a randomized, double-blind and counterbalanced fashion prior to force platform assessment of countermovement jump, drop jump and isometric mid-thigh pull performance. Strength endurance was measured across two sets of CP, SP, DL, and SQ at 70% 1RM until failure. Pre-exercise perceptions of motivation and arousal were also determined. Caffeine increased perceived readiness to invest mental effort (p = .038; ηp2=.156), countermovement jump height (p = .035; ηp2=.160) and SQ repetitions until failure in the first set (p < .001; d = .481), but there was no effect of delivery mode (p > .687; ηp2<.015). Readiness to invest physical effort, felt arousal, drop jump height, countermovement jump, drop jump and isometric mid-thigh pull ground reaction force-time characteristics and repetitions until failure in CP, SP and DL were not affected by caffeine administration or mode of caffeine delivery (p > .0.052; ηp2< .136). 3 mg.kg-1 caffeine administered via capsule, gum or mouth rinse had limited effects on muscular strength, power, and strength endurance. Small effects of caffeine on CMJ height could not be explained by changes in specific ground reaction force-time characteristics and were not transferable to DJ performance, and effects specific to the SQ RTP exercise underpin the complexity in understanding effects of caffeine on muscular function. Novel modes of caffeine administration proposed to evoke benefits via distinct mechanisms did not offer unique effects, and the small number of effects demonstrated may have little translation to a single performance trial when data examining direct comparison of each caffeine vehicle compared against a mode matched placebo is considered.

Examining the Independent and Interactive Carryover Effects of Cognitive and Physical Exertions on Physical Performance.

This study compared the effects of prior cognitive, physical, and concurrent exertion on physical performance. Fatiguing cognitive and physical exertions have been shown to negatively affect subsequent task performance. However, it is not clearly understood if concurrent physical and cognitive effort may exaggerate the negative carryover effects on physical task performance when compared to cognitive or physical exertion alone. Twenty-five participants completed four isometric handgrip endurance trials on different days. The endurance trials were preceded by four, 15-minute experimental manipulations (cognitive, physical, concurrent, control). Electromyography (EMG) and force tracing performance were monitored, with handgrip strength measured pre and post. Subjective ratings of mental and physical fatigue, as well as affect, motivation, and task self-efficacy, were also assessed. Handgrip strength decreased following both physical (-14.4% MVC) and concurrent (-12.3% MVC) exertion manipulations, with no changes being observed for the cognitive and control conditions. No differences were observed across conditions for endurance time, EMG, nor tracing performance. When compared to the control conditions, perceptions of mental and physical fatigue were higher following the experimental manipulation. Endurance trial self-efficacy was lower for the mental, physical and concurrent conditions compared to control. The concurrent condition resulted in similar decreases in strength as the physical fatigue condition, but otherwise resulted in similar carryover effects on endurance performance across all conditions. Further study is required at higher exposure levels, or for longer exposure durations, to further probe the influence of concurrent physical and cognitive effort on task performance. Concurrent cognitive and physical effort resulted in similar physical performance decrements to physical effort alone.

Generating variable length full events from partons

This paper presents a novel approach for directly generating full events at detector-level from parton-level information, leveraging cutting-edge machine learning techniques. To address the challenge of multiplicity variations between parton and reconstructed object spaces, we employ transformers, score-based models and normalizing flows. Our method tackles the inherent complexities of the stochastic transition between these two spaces and achieves remarkably accurate results. The combination of innovative techniques and the achieved accuracy demonstrates the potential of our approach in advancing the field and opens avenues for further exploration. This research contributes to the ongoing efforts in high-energy physics and generative modeling, providing a promising direction for enhanced precision in fast detector simulation.

The role of flood disaster information literacy in community preparedness in Tempe district Wajo regency South Sulawesi province Indonesia

The coast of Lake Tempe is one of the areas in Indonesia which is inhabited by approximately 500 people. Every year, the water of Tempe Lake rises and overflows, a form of vigilance for the surrounding community. This study aims to determine the Tempe community's level of information literacy towards floods and the role of disaster information literacy in community preparedness for floods. The method used in this research is descriptive qualitative. The results of this study indicate that disaster literacy is obtained through activities carried out by the government and mitigation carried out by the government, which can also be interpreted as taming natural disasters. In principle, Mitigation is physical and non-physical efforts in dealing with natural disasters. However, the people around Lake Tempe are not afraid and anxious about flooding and overflowing in Lake Tempe. It can be seen that the flood was not a disaster for the people in Lake Tempe. The role of disaster information literacy can be seen in the community's readiness to welcome floods by providing iron, wooden planks, and bamboo to increase the height and strengthen the community's houses while in the Tempe sub-district. Socialization and education about disaster literacy is an effort that needs to be made by the government to continue to change the mindset of the people of Wajo Regency, who think that flooding is not a disaster.

Speech-mediated manipulation of da Vinci surgical system for continuous surgical flow

AbstractWith the advent of robot-assisted surgery, user-friendly technologies have been applied to the da Vinci surgical system (dVSS), and their efficacy has been validated in worldwide surgical fields. However, further improvements are required to the traditional manipulation methods, which cannot control an endoscope and surgical instruments simultaneously. This study proposes a speech recognition control interface (SRCI) for controlling the endoscope via speech commands while manipulating surgical instruments to replace the traditional method. The usability-focused comparisons of the newly proposed SRCI-based and the traditional manipulation method were conducted based on ISO 9241-11. 20 surgeons and 18 novices evaluated both manipulation methods through the line tracking task (LTT) and sea spike pod task (SSPT). After the tasks, they responded to the globally reliable questionnaires: after-scenario questionnaire (ASQ), system usability scale (SUS), and NASA task load index (TLX). The completion times in the LTT and SSPT using the proposed method were 44.72% and 26.59% respectively less than the traditional method, which shows statistically significant differences (p &lt; 0.001). The overall results of ASQ, SUS, and NASA TLX were positive for the proposed method, especially substantial reductions in the workloads such as physical demands and efforts (p &lt; 0.05). The proposed speech-mediated method can be a candidate suitable for the simultaneous manipulation of an endoscope and surgical instruments in dVSS-used robotic surgery. Therefore, it can replace the traditional method when controlling the endoscope while manipulating the surgical instruments, which contributes to enabling the continuous surgical flow in operations consequentially.

Rapid assessment of cardiac autonomic modulation and adaptive stress responses: Automatic calculation of time-varying parasympathetic, sympathetic, and Baevsky stress indexes

Cardiac autonomic modulation (CAM), which is regulated by the balance between the sympathetic and parasympathetic nervous systems, is involved in various physiological and pathological conditions. Heart rate variability (HRV) analysis has been used to explore the complex relationship between the brain and heart, as described by Porges&amp;rsquo; polyvagal theory and Thayer&amp;rsquo;s neurovisceral integration model. Recently, an automated calculation of new parasympathetic, sympathetic, and Baevsky stress indexes based on HRV parameters has been introduced for faster and more comprehensive CAM assessment, though their normal ranges remain undefined. This study aimed to determine the average values of these indexes in a healthy population of different ages during rest, daily activities, non-rapid eye movement sleep, graded physical effort, and acute psychophysiological stress. At rest, the parasympathetic and sympathetic indexes were consistently within the proposed normal range and inversely related. However, Baevsky stress index values from Kubios were higher than expected, conflicting with the assumption that they are simply the square root of those calculated using the original formula. Despite this, time-varying assessment of all indexes can provide valuable insights into CAM adaptation during physical effort and acute psychophysiological stress in real-world critical situations. Notably, our novel finding shows that the inverse correlation between parasympathetic and sympathetic/stress indexes under stress is better explained by non-linear functions, offering a potential new measure of brain&amp;ndash;heart interaction during real-life critical events.

‘Into the darkness’ – The caving community and their tourist experiences. The Polish case

Descent into the underground requires from explorers not only a high level of physical endurance, technical skills, and ability to use specialized equipment, but also psychological adaptation to severe cave conditions: the darkness, the coldness, and the unknown. The paper focuses on mental states and emotions that accompany cave descents at every stage of the tourist experience. The study examines cavers' tourist motivations as well as perceived benefits of this kind of physical activity. The research aims at the Polish caving community. The study indicates that participation in cave exploration for respondents undertaking cave challenges outside of regular tourism is generally the result of a combination of equally strong factors, rather than a single dominant motivation. The benefits of cave exploration are inwardly directed, those related to creating one’s external image were of marginal importance among survey respondents. A state of ‘focus and concentration’ accompanies cavers during almost the entire stay in cave what not lessen a sense of overall satisfaction, joy, and excitation. To some extent, anxiety, anger, and rarely fear, shape the cave tourist experience. Management implicationsThe tourism product of any kinds of tourism should meet the expectations and needs of their participants. Dedicated speleotourists visiting sites outside mass tourism in popular show caves are leading by the complex of motivations typical for tourism as such. However, in the study analysed, the search for beauty and aesthetic impressions next to experiencing the unknown and novelty are explicitly significant motivators for cave exploration, even more important than looking for sport challenges and physical effort. This observation underlines cognitive and emotional meaning, not only sport character of cave exploration.The research might suggest the general direction in preparation of the offer for dedicated cave tourists: they do not require the creation of new infrastructure (e.g. in terms of cave accessibility) or provision of new amenities, but possibilities of the improvement of technical skills, while enjoying the beauty of the caves, with maintaining a balance between commercialization and the sense of uniqueness and exclusivity of the product.As pristine and unexplored caves constitute a ‘non-renewable resource,’ thus there is a need for redefinition of ‘the unknown’ and ‘the new’ concepts in cave tourism practiced by dedicated cave tourists (far beyond the geographical sense). The result of this procedure might help meet the expectations of dedicated cave tourists toward their tourist experiences and the attractiveness of sites.The explorations of dedicated cave tourists occur outside or on the fringes of tourism. To include them in the mainstream of broader tourism, it is necessary to find a balance between commercialization and the uniqueness and exclusivity of the product. The latter should provide satisfaction both in the area of physical well-being and the emotional sphere (sense of community, strengthening bonds).The study revealed the literature gap in terms of existential authenticity and the recognition of aesthetic and bodily experiences in cave tourism outside of popular show caves.

Influence of punishments associated with task outcomes in physical and mental efforts performed by semi-elite soccer players during training tasks

ABSTRACT Punishing application associated with the task outcomes is a familiar strategy used by soccer coaches during training, but it has been mainly remained in the research background. To date, no previous studies have addressed the effects of punishments on soccer players’ physical and mental efforts during on-field training sessions. Voluntarily, 40 semi-elite male soccer players from two Spanish teams of the same club participated in the study (M age = 22.90 yrs, SD = 5.60 yrs), performing two training sessions with the same tasks, but different in the use or non-use of punishments associated with the task outcomes. Physical load was registered using Polar Team and Ratio of Perceived Exertion. Mental load was estimated by the NASA-Task Load Index and mental fatigue was collected using a Visual Analogue Scale. A portable eye tracker was used to seek the effects of punishment manipulation on ocular metrics. After training, players achieved higher values of peak and mean heart rate, peak and mean speed, distance/minute, and number of sprints at the session with punishments, compared to the session without them. The punishments also influenced participants’ eye movement metrics because changes were found in pupil diameter, latency and velocity of saccades, and number of saccades and blinks when compared to the two training sessions. However, no differences were found between sessions for subjective mental load and fatigue variables. These findings have practical implications to the design of soccer training tasks because this emotional constraint influenced the physical load and objective mental load of the soccer players, but not their subjective measures of mental load and fatigue.

Monitoring The Effort Curve In Physical Education For Normal And Overweight Students Using Smartwatches And Mobile Applications

Study purpose. In physical education and sports lessons, correctly dosing effort is essential for optimising physical performance and adapting effort parameters, including breaks, in line with physiological principles. The study hypothesises that using smart-watches and mobile apps to monitor effort in middle school physical education lessons will reveal significant differences in effort and heart rate between overweight and average BMI students. Modern technology is expected to enhance understanding of students' physical exertion, facilitating adjustments to programs based on health status and fitness level. Material and method. The study involved 45 students (average age 13.5 years) using 15 Xiaomi 8 smart-watches, phones, Wi-Fi, the Mi Fit app, and other devices to analyse body composition. Data on heart rate and BMI were collected during lessons, which followed the same theme and effort dosage. The Mi Fit app provided detailed aerobic and anaerobic exertion analyses. Parental consent was obtained, and data collection was done under routine lesson conditions. The technology aimed to improve performance and customise programs, offering a personalised approach to physical education. Real-time data transfer enabled accurate analysis of physical effort, promoting healthier lifestyles and better lesson adaptation by teachers. Results. A significant interaction between heart rate and BMI steps (p &lt; 0.01) shows different cardiovascular adaptations to exercise based on BMI. MANOVA confirmed the significant impact of these variables on heart rate, and post hoc comparisons showed differences between weight categories, except between overweight and extremely obese groups. These results highlight the need to tailor physical education programs to BMI categories to optimise cardiovascular health and performance. Conclusion. Results suggest that monitoring the effort curve using modern technologies, such as smart-watches and mobile apps, provides valuable information for adjusting and optimising physical education lessons, especially for overweight and obese students.

Physical effort precrastination determines preference in an isometric task.

How the brain decides when to invest effort is a central question in neuroscience. When asked to walk a mile to a destination, would you choose a path with a hill at the beginning or the end? The traditional view of effort suggests we should be indifferent-all joules are equal so long as it does not interfere with accomplishing the goal. Yet, when total joules are equal across movement decisions, the brain's sensitivity to the temporal profile of effort investment remains poorly understood. Here, we sought to parse the interaction of time and physical effort by comparing subjective preferences in an isometric arm-pushing task that varied the duration and timing of high and low effort. Subjects were presented with a series of two-alternative forced choices, where they chose the force profile they would rather complete. Subjects preferred earlier physical effort (i.e., to precrastinate) but were idiosyncratic about preference for task timing. A model of subjective utility that includes physical effort costs, task costs, and independent temporal sensitivity factors described subject preferences best. Interestingly, deliberation time and response vigor covary with the same subjective utility model for preference, suggesting a utility that underlies both decision making and motor control. These results suggest physical effort costs are temporally sensitive, with earlier investment of effort preferred to later investment, and that the representation of effort is based on not only the total energy required but also when it is required to invest that energy.NEW & NOTEWORTHY We use a novel paradigm that differentiates physical effort costs, task costs, and time, where subjects choose between isometric arm-pushing tasks. Subjects prefer high physical effort earlier than later. They also decide faster and respond more vigorously the greater their preference. We find a generalizable subjective utility model that includes independent time-sensitivity of physical effort and task costs. Together, we demonstrate that subjective effort includes not only the total effort invested but also its timing.

Capturing Individual Differences in the Valuation of Physical Effort

Capturing Individual Differences in the Valuation of Physical Effort
