Exploring the Effects of Augmented Reality on the Emotion Recognition Skills of Autistic Children

Autistic children have significant difficulties in recognizing and labeling emotions, difficulties which may hinder the natural development of their ability to express and regulate further emotions. The purpose of this study was to evaluate the effect of an augmented reality emotion recognition program (ARERP) delivered in a group format on the emotion recognition of young autistic children. This study employed a concurrent multiple probe design across behaviors to evaluate the effects of the training on children’s emotion recognition. The target behavior was recognizing three emotion sets: positive, negative, and complex. The sequence of conditions included pre-test, baseline, training, post-test, and follow-up sessions. Positive results were found across all four children who all achieved 100% accuracy in identifying emotions during the training. Further, the emotion recognition skills were successfully maintained for 4–7 weeks post-training, with observed generalization to untrained still pictures and GIFs. This study provides preliminary evidence supporting the effectiveness of AR-based group training for young autistic children.

Effectiveness of 12-Week Core Stability Training on Postural Balance in Soccer Players With Groin Pain: A Single-Blind Randomized Controlled Pilot Study.

Core stability training (CST) is effective in improving postural balance, core endurance, and self-reported outcomes in different populations. This study aimed to investigate the effect of CST in soccer players with groin pain (GP). CST would improve postural balance performance, core endurance, and self-reported outcomes in soccer players with GP. Randomized controlled trial. Level 2. Soccer players with GP who met the selection criteria were assigned randomly to a CST (CSTG, n = 10) or a control (CG, n = 10) group. The CG undertook no additional physical activity program besides their usual training. The CSTG performed a 12-week CST comprising 76 ~75 min sessions. Static (force platform) and dynamic (Y-Balance test) postural balance, core endurance (McGill trunk endurance tests), and self-reported outcomes (Copenhagen Hip and Groin Outcome Score [HAGOS]) were assessed before and immediately after the 12-week CST. Significant improvements were seen in dynamic postural balance (P = 0.04 to <0.01), HAGOS scores (P = 0.02 to <0.01), and core endurance measures (P < 0.01) in the CSTG in posttest compared with pretest session and compared with CG. Static bipedal postural balance measures showed significant improvements (eyes open, P = 0.02; eyes closed, P < 0.01) in the CSTG in posttest compared with pretest session. However, no significant differences (P > 0.05) were observed between CSTG and CG after the training period. A 12-week CST improved static (foam surface) and dynamic postural balance, core endurance measures, and HAGOS scores. The beneficial effect of CST on improving postural balance, core endurance, and self-reported outcomes in soccer players with GP suggests that this training would be an important feature of rehabilitation programs for these players. Coaches and clinicians should prioritize CST training when designing rehabilitation programs.

Evaluating the Influence of the ACTN3 rs1815739 Gene Polymorphism on the Performance of Physically Active Adult Males in the Arrowhead Agility Drill Test

The alpha actinin-3 gene (ACTN3) is a significant candidate gene among genetic markers that determine athletic ability. The ACTN3 gene is responsible for the creation of the actin protein in fast-twitch muscle fibers, which is associated with muscle power and speed. The objective of this study was to analyze the changes in performance of the arrowhead agility drill test and the distribution of genotype variants in the ACTN3 rs1815739 gene polymorphism in physically active adult males after a 6- week training period. The research will focus on a cohort of 58 male students, aged 19-24, who are enrolled in the Faculty of Sports Sciences and participate in swimming activities. Genomic DNA was extracted from swab samples obtained from participants using the Buccalyse DNA Extraction Kit from Isohelix, following the manufacturer's supplied technique. The study findings revealed that there was no statistically significant difference between all three genotypes when comparing the pre-test and post-test values of the sample group in terms of left and right foot characteristics. Within this framework, it is acknowledged that the outcomes derived from our investigation could potentially influence the research findings. These aspects include the restricted sample size and the incapacity to regulate individual variances such as concentration and motivation during the pre-test and post-test sessions. Nevertheless, it is believed that the results obtained from our study could potentially enhance future research and literary works in the same field.

The result of the research indicated that was significant effect of using RCRR strategy towards students’ redading comprehension. It can be seen from p-value which was smaller than the alpha value(0,000&lt;0,05). It is concluded that, using RCRR strategy gave significant effect towards students’ reading comprehension on narrative text.

Body Water Compartment and Sympathovagal Balance: Association with Visuomotor Retention in Young Adults

Cognitive functions are important for visuomotor learning and are associated with physiological factors such as body fluid compartment and cardiovascular reactivity. Previous studies found that body fluid compartment is associated with brain blood flow, which is regulated via sympathovagal balance. However, more evidence is needed to determine whether body fluid compartment and cardiovascular reactivity are associated with visuomotor learning. The purpose of this study was to explore the relationship of body fluid compartment and cardiovascular reactivity to visuomotor learning. We hypothesized that these physiological factors are associated with overall learning retention using upper extremity (including feedforward, volitional, and feedback conditions). Methods: Thirty young adults (12 males, 24.6 ± 3.9 years, right hand dominant) participated in this study. Participants tracked a sinusoidal wave with left arm at pre-test, learning, and post-test sessions on the first visit and at retention test session on the second visit seven days later. Participants performed one set of nine trials during each test and five sets of three trials during learning. Resistance and wave velocity were different in each trial. Learning error was calculated by the averaged absolute distance between the tracking line and the target line. Heart rate (HR), systolic blood pressure (SBP), and low to high frequency power ratio of heart rate variability (LF/HF) were continuously recorded during baseline before pre-test and during tests and learning. We analyzed participants’ extracellular to intracellular body water ratio (ECW/ICW) using an InBody body composition analyzer and tested their cognitive function with Picture Sequence Memory (PSMT), Pattern Comparison Processing Speed, Dimensional Change Card Sort, Flanker Inhibitory Control and Attention, and List Sorting Working Memory Tests from NIH Cognitive Toolbox. Data were statistically analyzed using linear regression analysis and quartile analysis. Results: ECW/ICW was associated with young adults’ ability to retain visuomotor learning after one week (R2 = 0.138, p = 0.043), whereas HR, SBP, and LF/HF at each session were not significantly associated with visuomotor retention. No differences were found in pre-test error among quartiles of five cognitive tests. Significant differences in retention error among quartiles were only found in PSMT, with participants scoring in the highest quartile of PSMT having lower SBP during the first visit and lower retention error compared to the lowest quartile. This finding suggests that young adults with better episodic memory were less stressed during learning and had better visuomotor retention. Conclusion: These findings support that ECW/ICW is associated with not only cognitive function but also visuomotor retention. In addition, cardiovascular reactivity during visuomotor learning may provide information for retention behavior. Relationship of body water compartment and sympathovagal balance to feedforward and feedback conditions in learning will be further discussed.

Differential effects of high-fat diet on endocrine, metabolic and depressive-like behaviors in male and female rats

The complications of obesity extend beyond the periphery to the central nervous system (CNS) and include an increased risk of developing neuropsychiatric co-morbidities like depressive illness. Preclinical studies support this concept, including studies that have examined the effects of a high-fat diet (HFD) on depressive-like behaviors. Although women are approximately two-fold more likely to develop depressive illness compared to men, most preclinical studies have focused on the effects of HFD in male rodents. Accordingly, the goal of this study was to examine depressive-like behaviors in male and female rats provided access to a HFD. In agreement with prior studies, male and female rats provided a HFD segregate into an obesity phenotype (i.e., diet-induced obesity; DIO) or a diet resistant (DR) phenotype. Upon confirmation of the DR and DIO phenotypes, behavioral assays were performed in control chow, DR, and DIO rats. In the sucrose preference test, male DIO rats exhibited significant decreases in sucrose consumption (i.e., anhedonia) compared to male DR and male control rats. In the forced swim test (FST), male DIO rats exhibited increases in immobility and decreases in climbing behaviors in the pre-test sessions. Interestingly, male DR rats exhibited these same changes in both the pre-test and test sessions of the FST, suggesting that consumption of a HFD, even in the absence of the development of an obesity phenotype, has behavioral consequences. Female rats did not exhibit differences in sucrose preference, but female DIO rats exhibited increases in immobility exclusively in the test session of the FST, behavioral changes that were not affected by the stage of the estrous cycle. Collectively, these studies demonstrate that access to a HFD elicits different behavioral outcomes in male and female rats.

The alpha1A antagonist tamsulosin impairs memory acquisition, consolidation and retrieval in a novel object recognition task in mice

Tamsulosin is an α1-adrenoceptor antagonist used to treat benign prostatic hyperplasia. This drug exhibits high affinity for α1A- and α1D-adrenoceptor subtypes, which are also expressed in the brain. While dementia symptoms have been reported after administration of tamsulosin in humans, studies on its effects on the rodent brain are still rare. The present study investigated the effects of tamsulosin (and biperiden, an amnesic drug) on cognitive performance in the object recognition task (ORT). Tamsulosin (0.001–0.01 mg/kg) was orally administrated in mice at three distinct time points: pre-training, post-training and pre-test session. Tamsulosin 0.01 mg/kg impaired object recognition regardless of when it was injected, whereas at lower doses did not affect mouse performance in the ORT. Biperiden also impaired acquisition and consolidation of object recognition in mice. Furthermore, the effects of tamsulosin on locomotion, motivation and anxiety were excluded as potential confounding factors. At all doses tested, tamsulosin did not alter distance moved, time spent exploring objects in the ORT, and anxiety-related behaviors in the elevated plus-maze test. By contrast, diazepam evoked a significant reduction of anxiety-like behaviours. In conclusion, tamsulosin impaired memory acquisition, consolidation and retrieval in an object recognition task in mice, thus affecting memory performance in a non-specific phase manner. These findings contribute to our understanding of the potential adverse effects of tamsulosin, and shed light on the role played by α1-adrenoceptors, particularly α1A- subtype, in cognitive processes.

Spiritual parenting for the community of Tanjung Dayang Selatan Village, Ogan Ilir Regency

The laws on child protection and the national education system outline the roles and responsibilities of parents towards their children. However, the reality in Indonesia, particularly in rural areas, reveals that many parents still neglect their children's education and spiritual development, leading to high rates of school dropout and moral decline among children. The objective of community service program is to impart an understanding of Islamic spiritual parenting concepts to the target audience, enabling its application within the community. This community service initiative comprises three main agendas: pre-test, socialization or counseling sessions on family sociology and spiritual parenting, and post-test evaluations. The results of the activity demonstrated a 33% increase in participants' knowledge after engaging in spiritual parenting discussions.

Education and Screening on Non-Communicable Diseases in Simokerto District, Surabaya, Indonesia

Non-communicable diseases (NCDs) are one of the leading causes of death in the world. Indonesia is one of the countries facing the problem of both communicable diseases and non-communicable diseases (NCDs). Non-communicable diseases are usually asymptomatic and do not show certain clinical signs, so most people are not aware of the dangers of non-communicable diseases. Non-communicable diseases (NCDs) are one of the health problems in society that has increased every year, and is the largest contributor to the incidence of death in Indonesia. Non-communicable diseases can be triggered by a lack of physical activity, smoking, ineffective diet, stress, which can lead to increased pressure, increased blood sugar, and increased blood fat. The purpose of this community service is to increase community knowledge and carry out health screening on non-communicable diseases in residents in RT 01 and RT 02 RW 04 Tambakrejo Village, Simokerto District, Surabaya City. The method of the community service are lectures on hypertension and diabetes mellitus followed by discussion and questions and answers. Furthermore, a demonstration on health screening in non-communicable diseases was conducted. To determine the benefits of this activity, the participants' knowledge was tested using questions in the pre-test and post-test sessions. Assessment of the participants' knowledge by counting the correct answers to the questions on the test sheet.There is an 80% increase in knowledge of residents about the management of hypertension and diabetes mellitus. The results of the screening identification obtained data that the body mass index of the community is as follows 45.2% of people with obese conditions; 41% of residents have grade 1 hypertension with blood pressure between 140- 159/90-99 mmHg; the results of random blood sugar checks are normal (79%); uric acid checks on residents have normal results (82%); and cholesterol levels in the body range normal, namely 52 people (71%). It is important to support residents' activities in improving healthy living behaviour through joint exercises.. It is expected that the cadres will maintain the performance that has been achieved, and form working groups in their respective neighbourhoods to share the health information in improving the level of health..

Sosialisasi Tingkat Pengetahuan Remaja Terkait Kecukupan Gizi Harian Anak Usia Remaja

Indonesia, as a developing country, generally has more people who are active or work primarily as farmers with middle to lower family economic status and low levels of knowledge. In particular, knowledge of the importance of daily nutritional needs is not very good. Increasing knowledge of daily nutritional needs is very necessary in order to make people aware of the importance of adequate nutrition for the development of the next generation. Various nutritional sources that can be used to increase nutritional intake, and have relatively cheap prices and can be reached by all groups. It is common knowledge that livestock products have complete nutritional content and high levels of nutrition. Among the livestock products that have quite high quality at affordable prices are eggs. Eggs can be used as a complementary source of nutrition, because eggs are an animal product that is rich in nutrients and easily digested by the human body. This community service is carried out in high school with the target of students so that they gain knowledge regarding the importance of nutritional needs for their physical and non-physical development. The results of implementing community service at SMK N 7 Southwest Maluku school went well in accordance with the strategy that had been prepared by the service team. The implementation of community service is generally divided into four sessions, namely the pretest session, the session providing service materials, the posttest session, and the awarding session.

Excellence Service Training For Members Of The West Manggarai Homestay Association (Asihom Mabar)

Currently, Labuan Bajo is a premium tourist destination. The status as a premium tourist destination has increased the tourism industry in Labuan Bajo. Tourism development in Labuan Bajo needs to be followed by the quality of tourism industry services, including accommodation services. One form of accommodation service is homestay. One of the obstacles homestays face is the inability to provide quality services to guests. Therefore, homestay managers in Labuan Bajo need excellent service training for homestay management. The implementation of this community service activity consists of three stages, namely preparation, implementation, and evaluation. At the implementation stage, the method used is lectures and discussions about service quality (SERVQUAL) and the five components of SERVQUAL. The pre-test and post-test methods were also used to measure the increase in understanding. There are six questions for the pre-test and post-test sessions. The pre-test results showed that the average level of correctness of the answers reached 89%, and the post-test results reached 93%. The correctness of the answers in the pre-test and post-test sessions showed that the participants experienced an increased understanding of quality services. Based on the results of the implementation of this excellent service training activity, it is recommended that homestay managers need training activities to improve their ability and understanding of homestay managers. In addition, training with the theme of optimizing social media as a digital promotion channel is also needed by homestay managers in Labuan Bajo.

Acute effects of sprint training for hamstrings injury prevention on male college soccer players

In soccer, the hamstring is one of the most common injury portions. Among the various interventions, it can be assumed that modification of sprinting movement is directly helpful in hamstring injuries. The acute effects of sprinting interventions would be useful for pre-match interventions if they were immediate. The present study aimed to clarify the acute effects of sprint training for hamstring injury prevention on a collegiate soccer player. A total of twenty–seven male collegiate soccer players participated in the present study. Participants performed a 30 m sprint test as a pre-test after warming up. Subsequently, an hour-long sprint training session, targeting the modification of movements associated with hamstring injuries, was conducted, followed by a post-test involving a 30 m sprint. From these trials, 30 m time and kinematic variables associated with a hamstring injury; trunk angle, thigh angle and shank angle, were computed. The results revealed a significant positive modification in the trunk angle between the pre-test and post-test sessions. However, no marked differences were observed in 30 m time and other kinematic data. Therefore, sprinting modification was shown to have an acute effect on improving trunk angle without affecting the running speed.

Metacognitive Strategy Training Improves Decision-Making Abilities in Amnestic Mild Cognitive Impairment.

Mild cognitive impairment (MCI) is associated with deficits in decision-making, which is of utmost importance for daily functioning. Despite evidence of declined decision-making abilities, research on decision-making interventions for MCI is scarce. As metacognition seems to play an important role in decision-making, the present study's aim was to examine whether a metacognitive strategy training can improve MCI patients' decision-making abilities. Older adults-patients of a day care center, diagnosed with amnestic MCI (n = 55) were randomly allocated in two groups, which were matched in gender, age and educational level. Τhe experimental group (n = 27, 18 women, mean age = 70.63, mean years of education = 13.44) received the metacognitive strategy training in parallel with the cognitive and physical training programs of the day care center, and the active control group (n = 28, 21 women, mean age = 70.86, mean years of education = 13.71) received only the cognitive and physical training of the center. The metacognitive strategy training included three online meeting sessions that took place once per week. The basis of the intervention was using analytical thinking, by answering four metacognitive-strategic questions, to make decisions about everyday situations. To examine the efficacy of the training, the ability to make decisions about everyday decision-making situations and the ability to apply decision rules were measured. Both groups participated in a pre-test session and a post-test session, while the experimental group also participated in a follow-up session, one month after the post-test session. The results showed that the experimental group improved its ability to decide, based on analytical thinking, about economic and healthcare-related everyday decision-making situations after they received the metacognitive strategy training. This improvement was maintained one month later. However, the ability to apply decision rules, which requires high cognitive effort, did not improve. In conclusion, it is important that some aspects of the analytical decision-making ability of amnestic MCI patients were improved due to the present metacognitive intervention.

Penggunaan Metode Game Development Life Cycle (GDLC) Untuk Memudahkan Belajar Bahasa Inggris Dalam Media Game

The development of information and communication technology has developed rapidly in various fields such as in the field of education and the field of play. Technology that is often used in all circles is a smartphone, the use of smartphones in addition to work can also be used to play. Ownership of smartphones according to the survey approximately 81.7% are used to send messages, regarding education, especially English learning according to the EF EPI survey (Englisg Profiency Index) Indonesia is in position 80 in Asia and includes low profiency. It can be concluded that there are still many Indonesian people, especially elementary school children, who still do not know about English. Therefore, a solution is made to introduce English with the theme of writing (writing) on game media, in making this educational game using the GDLC (game development life cycle) method. Educational games need development because many of the mechanics in educational games have passive mechanics, therefore in this game added mechanics, namely endless runner. After making the Tiny Man Genius game, tests were carried out on elementary school children in grades 4 and 6 based on the results of the pre-test and post-test conducted, it looks quite good even though in the pre-test session 81.3% were still below 100 with a maximum score of 200, but in the second experiment, the post-test increased, namely 93.8% increased and 87.5% with scores above 100. After conducting the test, the children stated that 68.8% helped in learning English.

Emotional Availability (EA) Brief: Single Session Feedback and Coaching for Improving Fathers’ Emotional Availability for Children Across a Wide Developmental Spectrum

Fathers are a historically underrepresented population in developmental research and must be considered for their modern presentation in parenting processes. Emotional Availability (EA) is a construct that captures the parent-child relationship quality and predicts positive outcomes for children. A recently developed intervention, the EA Brief, is a program conceptualized for easy administration that may be utilized to improve father-child dyadic functioning across a range of child ages. The final sample of interested fathers was 18 fathers with children between 4-months and 13.5-years. For pretest sessions, all fathers completed surveys (demographic information, the Emotional Availability Self Report, and the Flourishing Scale) via Qualtrics, followed by a 20-minute filmed interaction via Zoom which was later coded for EA. Immediate Intervention Group (IIG) received one pretest before the intervention and one posttest after the intervention over a 3-5 week intervention delivery. The intervention involved a 2-hour interactive Zoom workshop where information about EA, attachment, and mindfulness was provided, a 1-hour individualized, Zoom EA feedback/coaching session, and two weeks of text reminders about the covered content. In contrast to the IIG, the Waitlist Control (WC) participants received two pretests (same assessments as above) separated by the 3-5 week time period corresponding to the timing of intervention delivery for the IIG. After the second pretest, they received the same intervention as the IIG. All IIG and WC fathers received posttest sessions (exact same assessments as for the pretests noted above). Across 16 target variables assessing EA, six observed variables showed post-intervention improvement (α &lt; 0.05) though no significant findings were found on self-reported measures. These findings suggest that fathers respond to programs that provide guidance for clinically informed, research-based parenting despite the program having limited effect on their self-perceptions of how they parent.

Effects of 12 weeks of caffeine supplementation and Zumba training on postural balance and cognitive performances in middle-aged women

The researchers aimed to examine the effect of 12-week supplementing (100 mg/day) caffeine with Zumba training on postural and cognitive performances in middle-aged women. Fifty-six middle-aged women who participated in this study, were randomized into; a caffeine-Zumba (CZG), Zumba (ZG) and control groups. In two-testing sessions, postural balance was evaluated using a stabilometric platform, and for cognitive performances, Simple Reaction Time and Corsi Block-Tapping Task tests were used. We found that ZG and CZG showed a significant improvement in postural balance on the firm surface condition (p < .05) in the post- compared to pretest session. Whereas, ZG showed no significant improvement in postural performance on the foam surface condition. Only CZG revealed significant enhancements (p < .05) in cognitive and postural, in the foam surface condition, performances. In conclusion, supplementing caffeine with 12-week Zumba training was effective in improving both cognitive and postural balance, even in challenging conditions, performances in middle-aged women.

Kilohertz-frequency interferential current induces hypoalgesic effects more comfortably than TENS

Recent research on transcutaneous electrical stimulation has shown that inhibiting nerve conduction with a kilohertz frequency is both effective and safe. This study primarily aims to demonstrate the hypoalgesic effect on the tibial nerve using transcutaneous interferential-current nerve inhibition (TINI), which injects the kilohertz frequency produced by the interferential currents. Additionally, the secondary objective was to compare the analgesic effect and comfort of TINI and transcutaneous electrical nerve stimulation (TENS). Thirty-one healthy adults participated in this cross-over repeated measures study. The washout period was set to 24 h or more. Stimulus intensity was set just below the pain threshold level. TINI and TENS were applied for 20 min each. The ankle passive dorsiflexion range of motion, pressure pain threshold (PPT), and tactile threshold were measured at the baseline, pre-test, test (immediately before ceasing intervention), and post-test (30 min after ceasing intervention) sessions. After the interventions, the participants evaluated the level of discomfort for TINI and TENS on a 10 cm visual analog scale (VAS). As the results, PPT significantly increased compared to baseline in test and posttest sessions of TINI, but not in those of TENS. Also, participants reported that TENS was 36% more discomfort than TINI. The hypoalgesic effect was not significantly different between TINI and TENS. In conclusion, we found that TINI inhibited mechanical pain sensitivity and that the inhibitory effect persisted long after electrical stimulation ceased. Our study also shows that TINI provides the hypoalgesic effect more comfortably than TENS.

Hand Sewn Anastomosis Skill Acquisition and In Vivo Transfer Using 3D-Printed Small Bowel Simulator

IntroductionGeneral surgery residents need to master the hand-sewn bowel anastomosis (HSBA) technique. However, practice opportunities outside of the operating room are rare, and commercial simulators are often costly. The objective of this study is to assess the efficacy of a new, affordable silicone small bowel simulator, made with a three-dimensional (3D) printed mold, as a training tool to learn this technique. MethodsThis was a single-blinded pilot randomized controlled trial comparing two groups of eight junior surgical residents. All participants completed a pretest using an inexpensive, custom developed 3D-printed simulator. Next, participants randomized to the experimental group practiced the HSBA skill at home (eight sessions), while those randomized to the control group did not receive any hands-on practice opportunities. A posttest was done using the same simulator as for the pretest and practice sessions, and the retention-transfer test was performed on an anesthetized porcine model. Pretests, posttests and retention-transfer tests were filmed and graded by a blinded evaluator using assessments of technical skills, quality of final product, and tests of procedural knowledge. ResultsThe experimental group significantly improved after practicing with the model (P = 0.01), while an equivalent improvement was not noted in the control group (P = 0.07). Moreover, the experimental group's performance remained stable between the posttest and the retention-transfer test (P = 0.95). ConclusionsOur 3D-printed simulator is an affordable and efficacious tool to teach residents the HSBA technique. It allows development of surgical skills that are transferable to an in vivo model.

COMPARISON BETWEEN SPORTS DRINK AND COCONUT WATER ON CARDIOVASCULAR ENDURANCE PERFORMANCE AMONG FOOTBALL PLAYERS

A sports drink is a drink containing electrolytes and glucose, meanwhile coconut drink is known as a natural source of sports drink. Both drinks have the benefit of restoring energy and electrolyte, especially when ingested during strenuous physical activity that requires maximum endurance performance. The purpose of this study was to compare the effects of sports drinks and coconut drinks in enhancing cardiovascular endurance performance among UiTM football players. A total of 24 male participants representing Universiti Teknologi MARA Football Club (UiTM FC) were recruited. Participants were randomly assigned into three groups that are isotonic drink group (IDG) (n=8), the coconut drink group (CDG) (n=8), and the control group (n=8). Cardiovascular endurance performance was determined based on bleep test results at the pre-test and post-test. The intervention was conducted by giving a different type of drink according to the assigned group. IDG received 100 plus isotonic drink, CDG received a Vita Coco drink and CG were only given plain water. After the end of the pre-test session, the participants were given 2-hour to rest, and drinks were given according to their group. After 2-hour of rest, the participants continue with the post-test. The level of VO2 max was measured by an equation based on the bleep test results. The result shows there was a significant increment in pre-post-test VO2 max level within all groups, showing improvement in the mean level of VO2 max at post-test. The mean of pre-post-test VO2 max for the three respective groups was IDG 47.53 ± 6.32 to 49.46 ± 5.88 ml/kg/min, CDG 47.01 ± 3.45 to 48.81 ± 3.29 ml/kg/min and CG 47.06 ± 3.11 to 47.91 ± 3.43 ml/kg/min. However, there was no significant difference (p=0.276) between groups and pre-post-test VO2 max level. Looking at between groups effect, there was no significant effect (p=0.900) between these three groups and their VO2 max level. In conclusion, there was a significant positive change in the participant's pre-post-test VO2 max level for all three groups across two different periods at the pre-test and post-test. This suggests ingesting drinks between exercises substantially improved football players' cardiovascular endurance performance. However, there was no significant difference in the participants' cardiovascular endurance performance between the three groups. This indicates the type of drink does not influence the cardiovascular endurance performance among these football players.

Co-actors represent each other's task regularity through social statistical learning

Numerous joint action studies have demonstrated that certain low-level aspects (e.g., stimuli and responses) of a co-actor's task can be automatically and implicitly represented by us as actors, biasing our own task performance in a joint action setup. However, it remains unclear whether individuals also represent more abstract, high-level aspects of a co-actor's task, such as regularity. In the first five experiments, participants participated alongside their co-actors and responded to a mixed shape sequence generated by randomly interleaving two fixed order sequences of shapes in both the pre- and post-test sessions. But different intermediate practice sessions were undergone by participants across experiments. When practicing their own fixed order sequences in a mixed shape sequence, either together with another person (Experiment 1) or alone but informed that their partner was performing the same practice task in a different room (Experiment 4), participants exhibited a learning effect on their co-actors' practiced sequences. This indirect learning effect was absent when one of the co-actors did not participate due to either being removed from the practice (Experiment 2) or sitting still without offering responses (Experiment 3), as well as when the two co-actors practiced together but responded to two distinct properties of stimuli (e.g., colour and shape, respectively), with one having regularity and the other not. Finally, participants exhibited comparable direct learning effects on their own practiced sequences for Experiments 1–5 as when performing the pre-test, practice, and post-test sessions alone for Experiment 6. These results demonstrate that, when practicing together, or even when believing that they are acting together with a partner, co-actors do represent the task regularity of one another through social statistical learning and transfer this learned regularity to subsequent task performances. The present study extends our understanding of co-representation in the joint action context in terms of the more abstract and high-level task features people co-represent, such as a co-actor's task regularity.
