Background: Myotendinous stiffness is related to the collagen content of the muscle and tendon, and can be estimated during running by changes in vertical stiffness (kvert) and the resulting modifications of the spatiotemporal parameters (on-off ground asymmetry and landing-takeoff asymmetry). Supplementation with amino acids found in collagen, such as proline, glycine, and hydroxyl proline, combined with ascorbic acid, improve collagen synthesis and potentially result in improved mechanical strength and stiffness. Objectives: To determine if hydrolyzed collagen (HC) supplementation increases kvert and improves the spatiotemporal parameters during running in recreational triathletes. Methods: Nine active males (weight; 68.4 ± 5.7 kg, height; 171.8 ± 5.4 cm, age; 32.5 ± 4.1 years; Vo2max; 53.15 ± 2.19 mL/kg/min) were randomly distributed into a collagen group (CollG, n = 5) and a control group (CG, n = 4). Participants were supplemented for 4 weeks with 15g HC (CollG) or 15g placebo (CG; maltodextrin), 3 times per week. One hour after supplementation, the participants of both groups were asked to perform four repetitions of short sprints to further stimulate collagen synthesis. The ground reaction forces were recorded during running at 4.44 m s-1, 5.55 m.s-1, and 6.66 m.s-1 for assessment of kvert and the spatiotemporal step parameters. Results: Both groups increased kvert with speed (4.44 - 6.66 m s-1) from 24.8 ± 2.7 to 53.7 ± 16.5 N/m and from 25.1 to 49.8 N/m in the CollG and CG, respectively (P < 0.0001); however, there were no differences between groups before and after the supplementation period. As a consequence, the spatiotemporal parameters of running were also similar between groups. Conclusions: Four weeks of HC supplementation does not improve the bouncing mechanism of running in recreational triathletes.

Background: Gyms are among the places where various human infections can spread. One of the most important strategies to prevent infection spread among athletes is the use of strong and effective disinfectants. Objectives: The aim of this study was to evaluate and compare the antiseptic properties of chlorhexidine gluconate and pomegranate peel extract on staphylococcal isolates from sports mats. Methods: This descriptive-analytical study was performed on 22 Staphylococcus aureus, and Staphylococcus epidermidis isolates from a total of 105 sports mat samples. After identification of multi-drug resistant (MDR) staphylococcal isolates, the antimicrobial effect of chlorhexidine gluconate 20% and pomegranate peel extract was evaluated by broth microdilution according to the instructions of the Clinical and Laboratory Standards Institute. Results: Overall, 14 (66.7%) S. aureus and 8 (28.6%) S. epidermidis isolates resistant to azithromycin, linezolid, ciprofloxacin, vancomycin, and aztreonam were reported as MDR strains. The minimum inhibitory concentration (MIC) of chlorhexidine gluconate, which inhibited the growth of 90% of MDR S. aureus isolates was 250 μg/mL, which was 4-fold lower than the MIC of pomegranate peel extract (MIC90 ≥ 500μg/mL) and 2-fold lower against MDR S. epidermidis isolates (MIC90 ≤ 125 μg/mL). The MIC of chlorhexidine gluconate and pomegranate peel extract against S. aureus isolates differed significantly (P = 0.037). Conclusions: Compared to pomegranate peel extract, chlorhexidine gluconate has a higher antibacterial effect on MDR staphylococcal isolates from sports mats. Further research is required to verify the efficacy of this biocide for disinfection of gyms and sports clubs.

: Cerebrovascular accident (CVA) refers to any kind of damage caused by direct or indirect damage to the brain and its related elements. It is estimated that about 60% of brain injury victims have a permanent disorder. The consequences of CVA include reduced movement speed, weakness, functional impairment, reduced power, and balance. The purpose of this study was to investigate the effect of a 12-week selected training protocol on motor function following brain injury. In a semi-experimental study, 30 male subjects with a mean and standard deviation of 52.2 ± 5.4 years, weight 173.2 ± 4.2 kg, and height of 78.8 ± 5.3 cm were selected purposefully and accessible with inclusion and exclusion criteria. The participants were randomly divided into experimental (n = 15) and control groups (n = 15). In order to evaluate the physical-motor performance, 10-meter walking tests, get up and go tests, and climbing stairs tests were used. The training program lasted for 12 weeks, three sessions per week, and each session for 30 - 60 minutes. Data were analyzed by independent t-test and dependent t-test using SPSS-21 software at P ≤ 0.05 level. Based on dependent t-test and covariance test, there were significant differences in all three components of motor function (10 m walk time tests, get up and go test, and stair climbing test), there was a significant increase after training in men with CVA (P = 0.00). From the findings of this study, it can be concluded that the special exercises of the present study have a positive effect on motor function parameters of male patients with CVA, so it can be recommended as one of the most important rehabilitation strategies for these patients.

Context: SARS-COV-2 is a coronavirus belonging to the beta-coronavirus group that primarily targets the human respiratory system and causes symptoms similar to those of pneumonia. It should be noted that clinical symptoms of patients with COVID-19 vary in different people. These patients do not only experience respiratory problems. In fact, COVID-19 infection may show a variety of symptoms, including fever, shortness of breath, dry cough, nasal congestion, sore throat, nausea, vomiting, myalgia, arthralgia, fatigue (muscular and mental), joint swelling, headache, diarrhea, as well as some musculoskeletal symptoms. Therefore, the aim of this article was to investigate the major musculoskeletal problems in patients with COVID-19 through a narrative review study. Evidence Acquisition: This study collected the related published studies in the PubMed, ScienceDirect, and Google Scholar sources between 2019 - 2020. The main keywords were COVID-19, coronavirus, and musculoskeletal problems such as muscle fatigue, myalgia, arthralgia, and joint swelling. Results: The major musculoskeletal symptoms included muscle fatigue (25.6%), myalgia and arthralgia (15.5%), joint swelling (as reactive arthritis), and such conditions as joint limitations, tendon shortening, and muscle weakness due to prolonged bed rest. Conclusions: Our findings revealed that attention to musculoskeletal rehabilitation of patients with COVID-19 is as essential as their respiratory rehabilitation. Besides, it would be effective in reducing the physical complications of hospitalization, returning to independence and functional activities, as well as improving the quality of the patients’ life.

Background: Several studies have investigated risk factors for injury in different sports. However, little scientific information is available in relation to futsal injuries. Objectives: This study prospectively analyzed the influence of physical fitness parameters on the occurrence of futsal injuries in Iranian national teams. Methods: Prior to the season, all 55 players of 3 Iranian national futsal teams took part in a series of tests for physical fitness parameters such as cardio-respiratory fitness, muscle strength, body composition, flexibility, agility, and speed. Team physicians recorded all injuries, medical attention, and time loss due to the injury throughout the match and training sessions. Results: During 18 months, 54 futsal injuries were sustained by 32 players. Injured players had poorer performance at baseline in agility, speed, and vertical jump than players who did not incur an injury during the season. Lower maximal oxygen uptake (VO2max) values were associated with a higher injury risk. No differences between injured and uninjured players were observed in age, anthropometric data, flexibility, and lower extremity strength. Conclusions: Some physical fitness parameters were associated with the risk of injuries in futsal. Therefore, improving physical fitness might help to reduce the number of futsal injuries.

Background: Rugby is a contact sport, and the frequency of injuries is high. In our clinical experience with patients diagnosed arthroscopically with lateral meniscus tears in the middle segment, rugby players are more prevalent than players of other sports. We hypothesized that a meniscus tear in the middle segment is a common injury in rugby players and is associated with specific positions in rugby. Objectives: This study aimed to describe a series of lateral meniscus tears in rugby players. Methods: We retrospectively reviewed the medical charts of cases with an arthroscopically confirmed isolated lateral meniscus tear in the middle segment associated with rugby players in our center between 2006 and 2020. We investigated the epidemiology of injury, including the player position and phase of play, the symptoms; as well as imaging and arthroscopic findings. Results: Of 4452 cases (4666 knees) diagnosed arthroscopically with meniscus tears, 27 cases (28 knees) were isolated radial lateral meniscus tears in the middle segment, 26 of which were sports-associated, including 11 cases related to rugby. Among the 11 rugby players, 10 were forwards, 5 of whom were in the front row. The injury was associated with a tackle in 4 patients, while the phase of play of injury was unknown in 6 patients. In the clinical manual examination, tenderness and a positive hyperextension test had a relatively high sensitivity. In imaging examination, MRI depicted a characteristic image of a partial meniscal defect in the sagittal view. All patients underwent arthroscopic partial meniscectomy. The postoperative course was favorable. All patients returned to play rugby at the pre-injury competition level. Conclusions: In this study, radial lateral meniscus tears involving the middle segment frequently occurred in rugby players, mostly in forward positions. Arthroscopic partial meniscectomy achieved a return to play in all players.

Background: Visual skills play a pivotal role in athletic performance. However, in a professional setting, visual assessment is limited to a brief examination of visual acuity by the Snellen chart. This is while visual skills in sport comprise several other components. Objectives: This study aimed to evaluate the potential relationship between visual skills and sports injuries in professional soccer players. Methods: Through a prospective cohort study between September 2017 and October 2018, professional soccer league players were recruited for a complete eye examination including visual acuity, field of vision, and color discrimination as pre-competition examination. Any possible relationship between an abnormal eye finding and sports injury during the upcoming season was investigated. Results: A total of 386 male soccer players in 4 different playing positions were recruited from 16 league teams. Myopia, visual field defects, and green/blue/red color blindness were the most common visual impairments. Overall, there was no significant relationship between abnormal visual skills and the incidence of low back and upper extremity injuries among soccer players. However, a logistic regression model showed that the odds of quadriceps injury is 1.92 times higher (P-value: 0.005) for one diopter increase in both eyes' sum of refractive error. There is also an increased risk of concussion in players who have visual field defects (P-value < 0.005). Conclusions: Visual field defects can put soccer players at a higher risk for concussion. Moreover, uncorrected refractive eye errors will increase the incidence of lower limb injuries, mostly quadriceps injuries.

There is also an increased risk of concussion in players who have visual field defects (P-value < 0.005). Conclusions: Visual field defects can put soccer players at a higher risk for concussion. Moreover, uncorrected refractive eye errors will increase the incidence of lower limb injuries, mostly quadriceps injuries.","PeriodicalId":8847,"journal":{"name":"Asian Journal of Sports Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44226499","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}
