Background: Overweightness and obesity were major health problems in the last century. Chinese acupressure, traditional Iranian medicine, and aerobic exercise are low-risk and low-cost methods for its prevention and treatment. Objectives: The purpose of this study was a comparison of six weeks of Chinese acupressure with traditional Iranian medicine along with aerobic exercise on body weight and serum lipid factors in obese and overweight women. Methods: In this applied study, 24 obese and overweight women with a BMI above 25 were randomly divided into two groups of 12: Chinese acupressure and Iranian traditional medicine with aerobic exercise. In the Chinese acupressure group, the ear acupressure method was used using herbal seed and in the traditional Iranian medicine group, the lunch elimination method was used. The aerobic exercise program of the two groups was performed for six weeks, three sessions per week, and each session lasted 60 minutes with moderate intensity. Body weight, waist-to-hip ratio, lipid factors, blood sugar, blood pressure, and nutritional status of the subjects were measured before and after the study and were analyzed using independent and dependent t-tests. Results: The results of the present study showed that in the Chinese acupressure group, along with aerobic exercise, lipid factors improved, and body weight decreased. In the traditional Iranian medicine group, along with aerobic exercise, lipid factors improved, while blood pressure and blood sugar decreased significantly. In the intergroup results, there was a significant difference only in the blood sugar variable. Conclusions: Both Iranian and Chinese medicine, along with aerobic exercise, had a relatively similar effect on the variables.

Background: Snooker is a kind of cue sport in which skill plays an important role. To reach a professional level, snooker players must acquire many physical and mental skills. Strengthening the core muscles, which provide a foundation for a successful limb function in skill sports such as snooker, can be achieved by performing Pilates exercises. Objectives: The purpose of this study was to investigate the effectiveness of core muscle training on skill and balance for snooker players. Methods: In this study, 30 male snooker players were divided into Pilates (n = 15) and control groups (n = 15) by randomization. The Pilates group performed the mat Pilates exercises three sessions per week consisting of 30 minutes of Pilates training in addition to one hour of routine snooker training per session for six weeks. The control group performed one-hour routine snooker training three sessions per week at the same time period. To assess the players' skills, the line-up test was used to measure the break score, and the foul number test was used to calculate the foul number. Players' balance was evaluated by the stork balance test. All tests were performed pre and post 6 weeks of exercise for between and within- group comparisons. Results: Line-up and stork test scores were significantly increased (P < 0.05) in the Pilates group compared with the control group. However, there was no significant difference in the foul numbers between groups after Six weeks of Pilates exercises. Conclusions: Six weeks of mat Pilates exercises improves the snooker players' balance ability and break scores.

Background: Oxidative stress (OS) contributes to the development of some disorders, including malignancies, metabolic diseases, Alzheimer's disease, and Parkinson's disease. Objectives: The effects of coenzyme Q10 (CoQ10) supplementation on OS parameters have been assessed through an updated systematic review and meta-analysis. Methods: SCOPUS, PubMed, Cochrane Library, EMBASE, and Web of Sciences were used for article searching. Standardized mean difference (SMD) and its standard error were calculated using a random-effects DerSimonian and Laird model. All analyses were done using the STATA software version 16.0 (StataCorp, College Station, TX). Results: Based on twenty-five studies which remained to be incorporated in the meta-analysis, a statistically significant decrease in malondialdehyde (MDA) (SMD -2.74; 95% CI -3.89, -1.58; I2 = 96.9%) as well as nitric oxide (NO) (SMD -5.16; 95% CI -7.98, 2.34; I2 = 92.5%) was associated with CoQ10 supplementation, and a significant increase in total antioxidant capacity (TAC) (SMD 3.40; 95% CI 1.98, 4.83; I2 = 97.4%) and superoxide dismutase (SOD) activity (SMD 1.22; 95% CI 0.32, 2.12; I2 = 94.32%). Conclusions: The results showed no significant effect of CoQ10 supplementation on glutathione peroxidase (GPx), catalase (CAT) activities, and glutathione (GSH) levels. CoQ10 supplementation significantly reduced MDA and NO concentrations and increased TAC and SOD activity.

Background: Knee proprioception and neuromuscular control may be important factors contributing to re-injury occurrences. Objectives: To examine lower extremity muscular performance and knee proprioception preoperatively and 3 months after anterior cruciate ligament (ACL) reconstruction. Methods: Twelve participants underwent ACL reconstruction using the hamstring tendon. All participants were assessed for knee proprioceptive sense using an isokinetic dynamometer at 15° and 60° of knee flexion. Lower extremity muscular performance was examined using the single-leg squat test (SLS) with two-dimensional motion analysis in frontal and sagittal planes. Results: Mean absolute error angle at a 15-degree-target angle was significantly lower at three months after ACL reconstruction compared with the preoperative state (P = 0.04). Maximal knee flexion angle of the injured The SLS test showed a lesser knee flexion angle of the injured knee at three months after ACL reconstruction (P = 0.01), and injured knee proprioception at 60 degree-flexion did not significantly improve at the three month-postoperative stage. Conclusions: At three months after ACL reconstruction by hamstring graft tendon, knee proprioceptive sense at an inner range of knee extension improved. However, proprioception at the middle range did not significantly develop. The range of hip and knee motions using SLS related to strength changes that the knee extensor needs to improve, especially in the middle range.

Background: Parkinson's disease is a chronic, progressive and degenerative disorder of the central nervous system with four main symptoms of bradykinesia, tremor, muscular rigidity, and postural instability. Objectives: The effect of 12 weeks of Pilates and aquatic exercise on muscle strength and range of motion (ROM) in male patients with Parkinson's disease was assessed in this article. Methods: In this quasi-experimental study, 25 male patients reporting to Al-Zahra Hospital, Isfahan, were selected randomly and grouped in Pilates (n = 7), Aquatic exercise (n = 10), and Control (n = 8). The experimental groups received 1-hour sessions of training three times a week for 12 weeks. Muscle strength and ROM of each patient was measured through the Biodex Isokinetic System 3 before entering the study and after the final assigned session. Results: Pilates and Aquatic exercise groups had a significant improvement in ROM, while no significant difference was observed in the control group. Muscle strength and ROM increased significantly in the experimental groups compared to the control group (P < 0.05). The effect of Pilates on muscle strength was not significant (P < 0.05). Conclusions: Non-pharmacological modalities could be contributive in the patients with Parkinson's disease recovery and lead to significant improvements in their physiological parameters of muscle strength and ROM. Next to the pharmacological treatments, patients could benefit from inexpensive and readily available options like Pilates and aquatic exercises to alleviate the disease symptoms. Further studies should be run to reveal the aforementioned and plausible benefits of these complementary activities.

Background: Betatrophin/angiopoietin-like protein (ANGPTL8) is defined as an adipokine that regulates blood glucose and triglyceride levels. Objectives: This study aimed to evaluate the effect of propolis supplementation for the first time on serum levels of the hormone betatrophin, as a drug target in the treatment of dyslipidemia, in male endurance athletes for four weeks. Methods: 44 male athletes with an average age of 22 ± 3 years, a height of 177.5 ± 6.5 cm, and a weight of 76 ± 6 kg were selected in Qazvin. They were randomly divided into four groups: Supplementation, placebo, physical activity, and control. The supplementation and placebo groups received two 500 mg tablets of propolis and cellulose (in terms of shape and color, are similar to the original supplement and have no properties, flavor, and aroma) once after lunch and once after dinner, respectively. The drug treatment lasted for four weeks. The athletes' weight and serum levels of betatrophin were measured at the beginning and the end of 4 weeks of treatment. The ELISA method was used to assess the serum concentration of betatrophin. Analyzes were performed by the ANCOVA method. Results: The results showed that the long-term endurance training plus propolis supplementation would result in significant changes in the betatrophin serum levels and weight in participants (P = 0.001), but in the athletes without supplementation, these changes were not significant (P > 0.05). Conclusions: The results indicated that betatrophin serum levels in endurance athletes are increased by propolis supplementation, and their weight is decreased.

Background: Monitoring exercise intensity accurately is a constant concern for athletes and researchers. Objectives: The objective of this study was to compare the effects of controlling high-intensity interval training (HIIT) with heart rate (HTHR) and speed/time (HTST) on some fatigue-related variables. Methods: Twenty young male athletes (age 22.75 ± 2.5 years, weight 76.6 ± 8.8 kg, height 179.7 ± 6.5 cm) were randomly allocated to one of the two arms. Then two-time acute running was performed with intensity control based on heart rates (HR) and speed/time for 40 min on the treadmill with a one-week washout. In order to measure vVo2max, a VIFT test (30 - 15 intermittent fitness test) was taken. Serum levels of glucose, lactate, glycerol, pyruvate, and creatine kinase were measured before and at the end of each exercise. The normality of data was determined by the Shapiro-Wilk test. The t-test and univariate test were used to analyze within- and inter-group changes between the two types of HIIT, respectively. Results: The speed decreases at the identical intensity HTHR over time. The average speed in HTST was significantly higher (P < 0.05), but the maximum and minimum speed in HTHR was significantly higher and lower, respectively. The average distance covered by subjects in HTST was significantly higher (P < 0.05). The post-exercise blood fatigue indexes (i.e., pH, creatine kinase, lactate, glycerol, lactate/pyruvate, and glucose) in HTHR was significantly less compared to those in HTST. Heart rate increases at the identical intensity based on vVIFT in HTST gradually. Conclusions: In general, HTHR can exert the recovery and relative intensity between subjects more accurately. In fact, training based on HR, in contrast to speed/time, decreases internal load differences and increases external load differences between individuals.

Background: Researchers are pursuing the enhancement of sensorimotor skills through the application of virtual reality (VR) in the sports environment. Objectives: This study aimed to compare the performance and kinematics of VR with real-world dart-throwing. Methods: Twenty-four healthy junior high school boy students participated (aged = 13.66, SD = 0.48) in this semi-experimental study in the year of 2017. We examined mean radial and bivariate variable errors as the performance variables. The maximum flexion angle, release time angle, and angular velocity was examined as the kinematic variables. Standard dartboard, the Xbox360, the Kinect, and a high-speed camera (sampling at 240 Hz) were used to measure the performance and kinematics characteristics of upper limb motion. We used Kinovea 0.8.26 and MATLAB R2015b to analyze videos and data smoothing. One-way MANOVA was used to analyze variables. Results: The results revealed (P = 0.211) no significant differences between VR and real world (RW) training in acquisition and retention outcomes, F (4, 19) = 1.618. In addition, kinematic dependent variables (P = 0.414) had no significant difference between groups, F (6, 17) = 1.077. Conclusions: These findings achieved the same results in performance and kinematics of dart-throwing by VR intervention in the RW context. Basic similarities between VR and RW movement patterns in the same task bring motor skills improvement and transfer of learning.

Shirzad","doi":"10.5812/asjsm-123574","DOIUrl":"https://doi.org/10.5812/asjsm-123574","url":null,"abstract":"Background: Researchers are pursuing the enhancement of sensorimotor skills through the application of virtual reality (VR) in the sports environment. Objectives: This study aimed to compare the performance and kinematics of VR with real-world dart-throwing. Methods: Twenty-four healthy junior high school boy students participated (aged = 13.66, SD = 0.48) in this semi-experimental study in the year of 2017. We examined mean radial and bivariate variable errors as the performance variables. The maximum flexion angle, release time angle, and angular velocity was examined as the kinematic variables. Standard dartboard, the Xbox360, the Kinect, and a high-speed camera (sampling at 240 Hz) were used to measure the performance and kinematics characteristics of upper limb motion. We used Kinovea 0.8.26 and MATLAB R2015b to analyze videos and data smoothing. One-way MANOVA was used to analyze variables. Results: The results revealed (P = 0.211) no significant differences between VR and real world (RW) training in acquisition and retention outcomes, F (4, 19) = 1.618. In addition, kinematic dependent variables (P = 0.414) had no significant difference between groups, F (6, 17) = 1.077. Conclusions: These findings achieved the same results in performance and kinematics of dart-throwing by VR intervention in the RW context. Basic similarities between VR and RW movement patterns in the same task bring motor skills improvement and transfer of learning.","PeriodicalId":8847,"journal":{"name":"Asian Journal of Sports Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43314079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Background: The sedentary lifestyle caused by the COVID-19 quarantine has resulted in a devastating threat to human health due to stress and anxiety. Although infected individuals must stop exercising, exercise is not prohibited when without symptoms and complications. Whereas exercise can be effective in immune system reinforcement during the prevention, recovery, and post-recovery stages, COVID-19-recovered Individuals (CRI) must exercise under accurate considerations. Objectives: This study aimed to study exercise in cold weather for the CRI. Methods: This article overviews how different exercises affect the immune system. PubMed, Science Direct, and Google Scholar Databases and keywords including cold weather, COVID-19, immune system, and combined exercise were used to access scientific articles. Results: Recent reports show that different sports and exercises significantly improve COVID-19 symptoms, although there are many discrepancies among researchers in prescribing exercise programs (various training protocols, duration, and intensity). Also, CRI should avoid exercise in cold weather due to breathing complications Conclusions: Based on the present study, regular exercises (aerobic, resistance, and combined) with moderate intensity improve COVID-19 symptoms and the immune system.

: The current study investigates the relationship between simple reaction time, choice reaction time, and eye-hand coordination with peripheral vision in elite female table tennis players. Ten female table tennis players of the Iranian national team with a mean age of 19.7 ± 5.964, in the 18th Asian Games of 2018, Jakarta, participated via convenience sampling. The visual field was evaluated with the Humphrey automated perimetry. Choice and simple reaction time were assessed using Deary-Liewald reaction time tester software. In order to measure eye-hand coordination, the manual test of alternate-hand wall toss was used. Data were analyzed in statistical package for the social sciences using Pearson’s correlation. The results show that there was no significant relationship between simple and choice reaction time with peripheral vision in the left and right eyes. Also, results show that there was no significant relationship between eye-hand coordination with peripheral vision in the left and right eyes (P ≤ 0.05). The findings of this study show that experts in an activity visually searched their environment and located essential information more effectively and efficiently than novices. Therefore, we know that this visual feature is more a function of expertise than visual acuity.
