Introduction: physical inactivity affects metabolic health, and it has been described that physical exercise is able to counter these disturbances. Fibroblast growth factor (FGF) 21, resistin, and adiponectin are known cytokines that are sensitive to physical inactivity and exercise, however, their acute behaviour after one session of exercise in physically inactive young adults is unclear. Therefore, this study aimed to investigate the effects of a session of moderate-intensity continuous training (MICT) on the circulatory levels of FGF21, resistin, and adiponectin of physically inactive young adults. Material and methods: quasi-experimental study, where 20 physically inactive young adults, with body mass indexes between 18 and 30 kg/m2 were included. All performed one MICT session, with an intensity of 60% of their heart rate reserve on a treadmill for 30 minutes. Anthropometric measurements were evaluated (weight, height, waist and hip circumferences, lean and fat mass) prior to exercise, and venous blood samples were taken before and after exercise, where glycemia, insulin, lipid profiles, transaminases, FGF21, resistin, and adiponectin were assessed. Results: one MICT session decreased the circulatory levels of insulin (median 23.5 vs 10.9 µUI/ml; p<0.05) and FGF21 (median 527 vs 409 pg/ml; p<0.05). On the other hand, resistin and adiponectin levels did not change after exercise (both p>0.05). Conclusion: one MICT session decreased FGF21 plasma levels, whereas it did not modify resistin and adiponectin circulatory levels. The specific mechanisms behind this different behavior are needed to be elucidated in future studies. Keywords: exercise, sedentary behavior, metabolic syndrome, endurance training, cytokines

Elementary school-age children have started thinking logically and rationally; therefore, they need to be stimulated to think in a higher order. Higher-order thinking skills (HOTS) can help students think critically and creatively, solve problems and find solutions. Therefore, physical education teachers must participate in stimulating students' HOTS. This research aims to determine differences in physical education teachers' attitudes (certified and non-certified) based on gender, age and length of service toward HOTS stimulation in students. The method used in this research is comparative. The research sample consisted of certified and non-certified physical education teachers who taught in elementary schools in West Sumatra province, Indonesia, with 105 people (male = 77 and female = 28) aged 23-59 years. They were selected using accidental sampling. The instrument to measure stimulating higher-order thinking skills uses a Likert scale questionnaire consisting of 16 items. Data analysis was carried out using the Mann-Whitney U Test and Kruskal-Wallis H. The results of the study showed that differences in the attitudes of certified and non-certified teachers obtained a p-value < .05, while comparisons based on gender, age and work experience had a p-value> .05. So it can be concluded that the attitudes of certified and non-certified teachers towards HOTS stimulation are significantly different, while based on gender, age and length of service their attitudes towards HOTS stimulation are not significantly different.

The emotional skills of elementary school students in physical education subjects are still minimal. Therefore, a deeper exploration in this study was conducted to uncover it. This study aims to analyze the relationship of emotional intelligence with homogeneity psycho cognition strategies in physical education students in elementary schools. This study aims to analyze the relationship between emotional skills and homogeneity psycho cognition strategies in the physical education of elementary school students. The results showed a relationship between emotional skills and homogeneity psycho cognition strategies in physical education subjects. Some factors cause the absence of a relationship between physical education and homogeneity psycho cognition strategies of elementary school students. The results showed a relationship between emotional skills and homogeneity psycho cognition supported by adequate collaboration and emotional by all students. Other factors are reduced or limited interaction between students and the learning environment, aggravated by an economic burden that causes parents' emotional problems that impact children's emotions. Therefore, homogeneity psycho cognition can be recommended in physical education learning to improve the emotional skills of elementary school students.

Physical exercise during fasting is an interesting therapeutic agent in preventing increased inflammation in obesity. Therefore, this study aims to prove the physiological impact of a combination of physical exercise and fasting on inflammatory risk factors in obese women. This research involved 18 obese women as research subjects who met the predetermined criteria and were then randomly selected. Subjects were divided into 2 groups: a control group (K1; n = 9) and a group that combined physical exercise and fasting (K2; n = 9). Physical exercise is done aerobically using a treadmill for 40 minutes at moderate intensity while fasting is done intermittently: fasting for 16 hours, followed by not fasting for 8 hours. The combination of physical exercise and fasting was carried out for 2 weeks. Blood samples were taken to measure the risk of inflammation, using the CRP biomarker, from the cubital vein in as much as 4 mL, which was carried out before and after treatment. Data analysis used a paired sample t-test with a significance level of 5%. Based on the research results, there are significant differences. The level of CRP reduction between the treatment and control groups (p ≤ 0.05). Based on the results of this research, physiological evidence shows that aerobic exercise during intermittent fasting reduces inflammatory risk factors in obese women. Therefore, aerobic exercise during fasting can be recommended as an approach to reducing inflammatory risk factors in obesity. Keywords: Obese women, aerobic exercise, intermittent fasting, risk of inflammation

This study aims to analyze the effects of augmented reality (AR) training in improving physical fitness and technical performance. An 11-week randomized controlled design was adopted in this study. This research involved sixty female athletes in Pencak Silat and Karate from Sriwijaya University (Indonesia). Participants were allocated into the experimental group, namely AR (Pencak silat: n=15, Karate: n=15) and control group (Pencak silat: n=15, Karate: n=15). Handgrip dynamometer, leg dynamometer test, medicine ball, standing long jump test, hexagon agility test, sit and reach test and multi stage test are used to measure physical fitness levels while the target punching test and target kick test are used to measure technical performance. The results of Student's t showed that there was a change in the mean value of AR (all, p < 0.05) and control only in MBT (p < 0.05) from baseline to final-test, ANOVA analysis we observed that there was an effect of Time on physical fitness (all, p < .001), there was a Group effect related to HDT (p < .001), MBT (p = 0.043), SART (p < .001), and MST (p < .001) and there was a Time * Group interaction related to HDT (p < .001), LDT ( p = 0.029), SLJT (p < .001), HAT ( p < .001), SART (p < .001), and MST (p < .001), there was an effect of Time on technical performance (all, p < .001), Group effect related to TPT (p = 0.004), and Time * Group interaction related to TPT (p = 0.001) and TKT (p < .001). Thus, we conclude that using AR for 11 weeks is an effective training method for improving the quality of physical fitness and technical performance of young athletes in combat sports.

Although most football players recover good physical function after anterior cruciate ligament (ACL) surgery, some do not return to their sport or to the same pre-injury level, and there is a risk of recurrence. Therefore, this study aimed to examine research on psychological aspects of ACL rehabilitation and Return to Play (RTP), as well as their influence on possible recurrence in football and futsal players. The search was conducted using the Scopus, PubMed, WoS, CENTRAL databases, and grey literature sources DART-Europe and OpenGrey. A total of nine studies met the inclusion criteria. The results indicated as the most evaluated psychological factor the psychological readiness to RTP through the Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI). Likewise, psychological interventions in ACL-injured football players have positive effects on mood states, reduces pain perception, and fear reinjury, among others. Risk profiles for recurrence included vulnerability to stress and high psychological readiness to RTP. Therefore, psychological interventions should be incorporated into the rehabilitation process and screening to identify players at risk for poor outcomes or recurrences. Additional research would help to understand the influence of other variables or optimal levels of psychological readiness to RTP.

Heart rate variability (HRV), the variation of time intervals between heartbeats, reflects the result of the interaction between the autonomic nervous system and the cardiovascular system. Hypoxia is a stressor that causes changes in HRV and a decrease in arterial oxygen saturation (SaO2). The aim of our study is to analyse if the time and frequency domains of HRV are affected after a hypoxia tolerance test in healthy participants as a function of gender. Material and methods: 23 healthy volunteers (11 women and 12 men) with a mean age of 23.08±2.99 performed a hypoxia tolerance test (11%, 5050 m) with the iAltitude simulator. Heart rate and SaO2 were monitored during the test and HRV frequency domain (FD) and time domain (TD) data were obtained. We analysed the five minutes before and after each session. Outcomes: Simulated altitude-induced hypoxia can cause changes in HRV in a group of healthy individuals. Statistically significant differences were also found between before and after the normobaric hypoxia test in the time-domain variables RRm, SDNN, HRm, HR STD, pNN50. In addition, in women statistically significant differences were found in RMSSD, and in the frequency-domain variables HF and LF/HF. While in males, statistically significant differences were found in SDNN. In both men and women, significant differences were observed in RRm, HRm and pNN50. Conclusion: The differences found in HRV after the hypoxia tolerance test indicate that females show a greater activation of the parasympathetic nervous system compared to males. While males showed greater sympathetic activation. Keywords: Heart rate variability, normobaric hypoxia, stress, autonomic nervous system.
