Latihan Interval (LI) merupakan salah satu metode latihan untuk meningkatkan dan mempertahankan kemampuan/kecepatan berlari dalam jarak dan waktu tempuh yang sudah ditentukan. Penelitian ini bertujuan menemukan gambaran respons fisiologis dan biolemis Kadar β-endorfin terhadap LI dengan berbagai macam intensitas latihan (tinggi, sedang, dan rendah) pada sprinter dan non- sprinter Metode. Penelitian ini menggunakan metode eksperimen semu yang terdiri dari tiga tahap pelaksanaan pengukuran. Subjek penelitian ini adalah sprinter UKM 17 orang dan kelompok non-sprinter 15 orang. Setiap kelompok dibagi menjadi tiga kelompok yang lebih kecil berdasarkan intensitas latihan, yaitu kelompok latihan intensitas tinggi, sedang, dan rendah. Penelitian dilakukan dengan pengukuran karakteristik fisik berupa TB, BB, dan tes kecepatan lari 100 m serta pengambilan sampel darah sebanyak 3 kali 5 ml, untuk mengukur respons β-endorfin pada kondisi intensitas tinggi, sedang dan rendah sebelum. Data diambil sebelum diberi LI, selama LI, dan setelah istirahat 30 menit. Analisis data dilakukan menggunakan metode ELISA dengan uji statistik anova. Hasil dan kesimpulan. Hasil penelitian menunjuk bahwa dalam kelompok sprinter dan non sprinter dan non-sprinter tidak terdapat perbedaan yang bermakna terhadap peningkatan kadar β-endorfin. Akan tetapi terdapat peningkatan bermakna persentase kadar β-endorfin pada kelompok intensitas tinggi dibandingkan kelompok intensitas sedang dan rendah. Baik untuk kelompok sprinter maupun non-sprinter. Waktu istirahat 30 menit setelah LI belum cukup untuk mengembalikan kadar β-endorfin ketingkat awal. Molecular response endorphins against interval exercise with various intensity in sprinter AbstractInterval Exercise (LI) is one of the training methods to improve and maintain the ability or and speed of running in the distance and the time that has been determined. This study aims to find a depiction of physiological and biochemical responses of endorphins levels to LI with various intensity of exercise high, medium, and low on sprinter and non-sprinter. This research uses a quasi-experimental method which consists of three stages of a measurement implementation. The subjects of this research are the sprinter Activity sports unit of college Universitas Negeri Yogyakarta consist of 17 people and the non-sprinter group of 15 people. Each group is divided into three smaller groups based on the intensity of the exercise are high-intensity group, medium, and low. The study was conducted by measuring physical characteristics in the form of HB, WB, and 100m run a speed test and blood sampling as much as 3 times 5 ml to measure the response of endorphins in high, medium, and low-intensity constancy. The data were taken before being given LI, during LI, and after 30 minutes break. The analysis was done using the ELISA method with an ANOVA statistic test. The result and the conclusion. The results showed that in the sprinter and non-sprinter groups there was no significant difference in elevated endorphin levels. However, there was a significant increase in the percentage of endorphins in high-intensity groups compared to the medium and low-intensity groups, both for sprinter and non-sprinter groups. Rest time 30 minutes after the LI is not enough to restore the level of endorphins to the initial level.

Introduction: High intensity interval exercise (HIIE) is performed widely. However, the field possesses limited knowledge regarding the acute HIIE cerebrovascular response. Our objective was to characterize the middle cerebral artery blood velocity (MCAv) response during an acute bout of short interval HIIE in healthy adults. We hypothesized MCAv would decrease below BL 1) during HIIE, 2) following HIIE, 3) and 30-minutes after HIIE. As a secondary objective, we investigated sex differences in the MCAv response during HIIE. Methods: Fourteen healthy adults (7 male) completed the HIIE session. The 10-minute HIIE session included alternating 1-minute bouts of high-intensity and low-intensity intervals. MCAv, mean arterial pressure (MAP), heart rate (HR), and expired end tidal carbon dioxide (PETCO2), were recorded at BL, during HIIE, following HIIE, and 30-minutes after HIIE. Results: Contrary to our hypothesis, MCAv remained above BL for the HIIE duration. MCAv peaked at the third minute then decreased concomitantly with PETCO2. MCAv was lower than BL after HIIE (p=0.03). Thirty minutes after HIIE, MCAv returned to near BL values (p = 0.47). Women showed higher BL MCAv (x = 70.9 ± 8.1 cm/s) compared to men (x = 59.3 ± 5.8 cm/s, p = 0.01). A greater magnitude of MCAv response was observed in men resulting in non-significant differences during HIIE secondary to higher workload (p = 0.03). Conclusions: Collectively, these findings show that in healthy adults, MCAv remained above BL during a 10-minute short-interval HIIE and returned to resting values 30 minutes after exercise.

SUMMARY OBJECTIVE Psychological distress is an important mental health problem among university students. The goal of this study was to determine psychological distress and its associated risk factors among students in the Anhui province. METHODS A cross-sectional study was conducted in a sample of 1304 students. In this study, a self-administered questionnaire consisting of the general demography and General Health Questionnaire (GHQ-12) was completed. Psychological distress was assessed using the GHQ-12-item questionnaire. A dichotomous category split was imposed on the GHQ-12 for the purpose of analysis. A GHQ-12 score of 4 or higher indicated psychological distress. The data were analyzed by SPSS 20.0 system. RESULTS A total of 1304 samples were analyzed in this study. The results indicated that the education level of the father and mother was associated with the students’ psychological distress (P<0.001). A significant association was found between high-intensity exercise and low-intensity exercise and psychological distress. However, no significant difference was identified between gender and psychological distress (P=0.173). CONCLUSION The education level of parents, high-intensity exercise, and low-intensity exercise were associated with psychological distress. Our results suggest that it is indispensable to raise awareness of psychological disorders and its associated risk factors among university students. Further studies are required to develop appropriate interventions for high-risk groups.

Purpose: The effects of two different high-intensity training methods on 2,000 m rowing ergometer performance were examined in a feasibility study of 24 national-level rowers aged 18–27 years (17 males, 2,000 m ergometer time trial 6:21.7 ± 0:14.6 (min:s) and seven females, 2,000 m ergometer 7:20.3 ± 0:12.1. Habitual training for all participants was ~12–16 h per week).Methods: 16 high-intensity ergometer sessions were completed across two 3-week periods. Participants were allocated into two groups according to baseline 2,000 m time. High-intensity interval session-sprint-interval session (HIIT-SIT) completed eight HIIT (8 × 2.5 min intervals; 95% of 2,000 m wattage) followed by eight SIT (three sets of 7 × 30 s intervals; maximum effort). SIT-HIIT completed eight SIT sessions followed by eight HIIT sessions. Both a 2,000-m time trial and a progressive incremental test finishing with 4 min “all-out” performance were completed before and after each 3-week phase.Results: Both groups showed similar improvements in 2,000 m time and 4 min “all-out” distance after the first 3 weeks (2,000 m time: HIIT-SIT: −2.0 ± 0.6%, mean ± 90% CL, p = 0.01; SIT-HIIT: −1.5 ± 0.3%, p = 0.01) with no significant difference between groups. HIIT-SIT demonstrated the greatest improvements in submaximal heart rate (HR) during the progressive incremental test with eight sessions of HIIT showing a greater reduction in submaximal HR than eight sessions of SIT. The net improvement of 16 high-intensity sessions on 2,000 m time was −2.5% for HIIT-SIT (−10.6 ± 3.9 s, p = 0.01) and − 2.2% for SIT-HIIT (−9.0 ± 5.7 s, p = 0.01) and for 4 min “all-out” performance was 3.1% for HIIT-SIT (36 ± 25 m, p = 0.01) and 2.8% for SIT-HIIT (33 ± 27 m, p = 0.01).Conclusion: Eight sessions of high-intensity training can improve 2,000 m ergometer rowing performance in national-level rowers, with a further eight sessions producing minimal additional improvement. The method of high-intensity training appears less important than the dose.

Background and Objectives: The purpose of this study was to elucidate the effects of different exercise intensities in preventing the decline of cognitive function and lipolysis associated with a high-fat diet-induced obesity in growing mice. Material and Methods: Forty male C57BL/6 mice, aged 4 weeks, were divided into the normal diet (CO, n = 10) and high-fat diet (HF, n = 30) groups to induce obesity for 8 weeks. Subsequently, the HF group was subdivided equally into the HF, HF + low-intensity training (HFLT), and HF + high-intensity training (HFHT) groups, and mice were subjected to treadmill training for 8 weeks. Results: Following the 8-week training intervention, body weight and fat mass were significantly lower in the training groups than in the HF group (p < 0.05). Adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), and monoglyceride lipase levels were significantly higher in the training groups than in the HF group (p < 0.05), and the ATGL and HSL levels were significantly higher in the HFHT group than in the HFLT group (p < 0.05). The Y-maze test showed that the training groups had a higher number of total entries and percent alternation than the HF group (p < 0.05). Hippocampal nerve growth factor, brain-derived neurotrophic factor, and neurotrophin-3 levels were significantly higher in the training group than in the HF group (p < 0.05). However, there was no significant difference according to the exercise intensity among the groups. Conclusions: The results of this study suggested that low-intensity exercise is as effective as a high-intensity exercise in preventing the decline of cognitive function and lipolysis, and far more effective in terms of an expected efficiency of workload and prevention of side effects.

ABSTRACT Introduction The aim of this study was to assess the wear resistance of four bulk-fill composite resin restorative materials cured using high- and low-intensity lights. Materials and methods Twenty-four samples were prepared from each composite resin material (Tetric N-Ceram, SonicFill, Smart Dentin Replacement, Filtek Bulk-Fill) resulting in a total of 96 samples; they were placed into a mold in a single increment. All of the 96 samples were cured using the Bluephase N light curing unit for 20 seconds. Half of the total specimens (n = 48) were light cured using high-intensity output (1,200 mW/cm2), while the remaining half (n = 48) were light cured using low-intensity output (650 mW/cm2). Wear was analyzed by a three-dimensional (3D) noncontact optical profilometer (Contour GT-I, Bruker, Germany). Mean and standard deviation (SD) of surface loss (depth) after 120,000 cycles for each test material was calculated and analyzed using one-way analysis of variance (ANOVA) with a significance level at p < 0.05. Results The least mean surface loss was observed for SonicFill (186.52 µm) cured using low-intensity light. No significant difference in the mean surface loss was observed when comparing the four tested materials with each other without taking the curing light intensity into consideration (p = 0.352). A significant difference in the mean surface loss was observed between SonicFill cured using high-intensity light compared with that cured using low-intensity light (p < 0.001). Conclusion A higher curing light intensity (1,200 mW/cm2) had no positive influence on the wear resistance of the four bulk-fill composite resin restorative materials tested compared with lower curing light intensity (650 mW/cm2). Furthermore, SonicFill cured using low-intensity light was the most wearresistant material tested, whereas Tetric N-Ceram cured using high-intensity light was the least wear resistant. Clinical significance The wear resistance was better with the newly introduced bulk-fill composite resins under low-intensity light curing. How to cite this article Alkhudhairy F.

Introduction: Regular exercise training is a useful strategy to reduce inflammatory markers, but it is still unclear what type of training is better. Thus, this study compared the effects of 12-week of low-intensity resistance (Low-RT) and high-intensity interval aerobic training (High-IAT) on serum interleukin (IL)-6 levels and insulin resistance (IR) markers in obese and young men. Methods In this quasi-experimental study, 38 obese and young men (age = 28.4 ± 5.2 years and body fat% = 27.5 ± 1.5) randomly assigned into a low-RT (n=14), high-IAT (n=12) and control (CON, n=12) groups. An age-matched control group of non-obese men (age = 27.0 ± 5.9 years, body fat% = 15.5 ± 2.6 and n=15) were also recruited for baseline comparison. Subjects performed the training programs (Low-RT: 10 exercises at 30-50% of 1-repetition maximum, and High-IAT: 16-minute of interval running at 80-90% of maximum heartbeat with a 3-minute recovery between intervals) for 12 weeks and 3-day a week. Data analyzed using SPSS version 18. Results: The independent t-test showed that the concentrations of glucose (P = 0.01), insulin (P = 0.04) and IR-index (P = 0.02) in obese men was higher than the non-obese at baseline, but no significant difference was noted for IL-6 (P = 0.14). The 2-factor analysis of variance revealed that insulin and IR-index similarly and remarkably decreased in response to the training (P < 0.05), but remained unchanged with glucose and IL-6 (P > 0.05). Conclusion: In summary, insulin resistance markers in the obese men group were higher than in the non-obese men group, but no significant difference was detected in IL-6 in these groups. Insulin and IR-index decreased remarkably and similarly after training programs, but no significant changes were found in glucose and IL-6.

Numerous studies have shown that facial expressions influence trait impressions in the Western context. There are cultural differences in the perception and recognition rules of different intensities of happy expressions, and researchers have only explored the influence of the intensity of happy expressions on a few facial traits (warmth, trustworthiness, and competence). Therefore, we examined the effect of different intensities of Chinese happy expressions on the social perception of faces from 11 traits, namely trustworthiness, responsibility, attractiveness, sociability, confidence, intelligence, aggressiveness, dominance, competence, warmth, and tenacity. In this study, participants were asked to view a series of photographs of faces with high-intensity or low-intensity happy expressions and rate the 11 traits on a 7-point Likert scale (1 = “not very ××,” 7 = “very ××”). The results indicated that high-intensity happy expression had higher-rated scores for sociability and warmth but lower scores for dominance, aggressiveness, intelligence, and competence than the low-intensity happy expression; there was no significant difference in the rated scores for trustworthiness, attractiveness, responsibility, confidence, and tenacity between the high-intensity and low-intensity happy expressions. These results suggested that, compared to the low-intensity happy expression, the high-intensity happy expression will enhance the perceptual outcome of the traits related to approachability, reduce the perceptual outcome of traits related to capability, and have no significant effect on trustworthiness, attractiveness, responsibility, confidence, and tenacity.

Objective: To find and compare the clinical and psychological effects of low and high-intensity aerobic training combined with resistance training in community-dwelling older men with post-COVID-19 sarcopenia symptoms. Design: Randomized control trial. Setting: University physiotherapy clinic. Participants: Men in the age range of 60–80 years with post-COVID-19 Sarcopenia. Intervention: All participants received resistance training for whatever time of the day that they received it, and that in addition they were randomized into two groups like low-intensity aerobic training group ( n = 38) and high-intensity aerobic training group ( n = 38) for 30 minutes/session, 1 session/day, 4 days/week for 8 weeks. Outcomes: Clinical (muscle strength and muscle mass) and psychological (kinesiophobia and quality of life scales) measures were measured at the baseline, fourth week, the eighth week, and at six months follow-up. Results: The 2 × 4 group by time repeated measures MANOVA with corrected post-hoc tests for six dependent variables shows a significant difference between the groups ( P < 0.001). At the end of six months follow up, the handgrip strength, −3.9 (95% CI −4.26 to −3.53), kinesiophobia level 4.7 (95% CI 4.24 to 5.15), and quality of life −10.4 (95% CI −10.81 to −9.9) shows more improvement ( P < 0.001) in low-intensity aerobic training group than high-intensity aerobic training group, but in muscle mass both groups did not show any significant difference ( P > 0.05). Conclusion: Low-intensity aerobic training exercises are more effective in improving the clinical (muscle strength) and psychological (kinesiophobia and quality of life) measures than high-intensity aerobic training in post-COVID 19 Sarcopenia.
