The aim of this research was to compare the effects of a technique-specific high-intensity interval training (HIIT) protocol vs. traditional taekwondo training on physical fitness and body composition in taekwondo athletes, as well as to analyse the inter-individual response. Utilising a parallel controlled design, sixteen male and female athletes (five females and 11 males) were randomly divided into an experimental group (EG) that participated in the technique-specific HIIT and a control group (CG) that participated in traditional taekwondo training. Both groups trained three days/week for four weeks. Squat jump (SJ), countermovement jump (CMJ), 5-metre sprint (5M), 20-metre shuttle run (20MSR), taekwondo specific agility test (TSAT), multiple frequency speed of kick test (FSKTMULT), total kicks, and kick decrement index (KDI), as well as body composition were evaluated. Results indicate that there are no significant differences (p > 0.05) in the factors group and time factor and group by time interaction (p > 0.05). Although percentage and effect size increases were documented for post-intervention fitness components in TSAT, total kicks, KDI, and 20MSR, responders and non-responders were also documented. In conclusion, a HIIT protocol based on taekwondo-specific technical movements does not report significant differences in fitness and body composition compared to traditional taekwondo training, nor inter-individual differences between athletes.

Video recording of surgical procedures is an important tool for surgical education, performance enhancement, and error analysis. Technology for video recording open surgery, however, is limited. The objective of this article is to provide an overview of the available literature regarding the various technologies used for intraoperative video recording of open surgery. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines using the MEDLINE, Cochrane Central, and EMBASE databases. Two authors independently screened the titles and abstracts of the retrieved articles, and those that satisfied the defined inclusion criteria were selected for a full-text review. A total of 2275 publications were initially identified, and 110 were included in the final review. The included articles were categorized based on type of article, surgical subspecialty, type and positioning of camera, and limitations identified with their use. The most common article type was primary-technical (29%), and the dominant specialties were general surgery (22%) and plastic surgery (18%). The most commonly cited camera used was the GoPro (30%) positioned in a head-mount configuration (60%). Commonly cited limitations included poor video quality, inadequate battery life, light overexposure, obstruction by surgical team members, and excessive motion. Open surgery remains the mainstay of many surgical specialties today, and technological innovation is absolutely critical to fulfill the unmet need for better video capture of open surgery. The findings of this article will be valuable for guiding future development of novel technology for this purpose.

Supplement Intake

Compared with adult athletes, rather little is known about supplementation behavior in adolescent athletes. This study’s aim was to determine elite adolescent athletes’ supplement use and sources of information relating thereto. A total of 430 (87%) of 496 questioned athletes returned the anonymized questionnaire. Thereof, 84% consumed at least one weekly supplement and 97% indicated some supplement intake during the previous 4 weeks. On average, 13.3 supplement servings were consumed per week. The 25th, 50th, and 75th percentile was 4.5, 10.5, and 20.0 servings per week, with a maximum of 67. The most prevalent supplements in use were multimineral products (41% of all athletes), multivitamins (34%), Vitamin C (34%), and Vitamin D (33%). Male athletes consumed significantly more Vitamin C and D, sports drinks, protein powder, and recovery products compared with female athletes; whereas, women consumed more iron supplements. The three most important motives for supplement use were recovery support (40%), health maintenance (39%), and performance enhancement (30%). The most frequent answers to the question “who recommended that you use supplements” were family/friends (36%), a physician (27%), and a trainer/coach (25%). The main three information sources about the supplements in use were the persons who recommended the supplementation (56%), the internet (25%), and information provided by supplement suppliers (11%). A positive doping attitude was associated with the consumption of performance enhancing supplements (p = .017). In conclusion, this study among elite adolescent Swiss athletes indicates a widespread and large-scale use of dietary supplements, which was associated with a low level of information quality.

The main method of research is to assess the technical performance and physical fitness of athletes-jumpers using the "Optojump Next" measuring system, video recording and photodiode chronometry of the run-up speed (the "Brower" system). The survey took place at the track and field arena of the Novogorsk sport center (Moscow region), as well as at the stadium of ‘Iug-Sport’ sport center, Sochi in 2016-2018. The study involved 15 qualified long jumpers (Candidates Master of Sports – Masters of Sports of International Class). Results of the study and their discussion. The obtained results of the study enable identification of the model characteristics of the Special physical training control tests of qualified long jumpers in the range of results from 7.25 to 8.25 m. We have also developed model characteristics of technical performance for male jumpers in the range of results from 6.60 to 7.80 m. We used the chart of technical performance for jumpers (Master of Sports E. A-va) to reveal the lagging indicators of special sprint fitness: speed on the 5th step away from the bar; speed on the 4th step away from the bar; speed on the 3rd step away from the bar; pace of running step on the 3rd step away from the bar; average speed on the 3rd – 4th steps away from the bar; average speed on the 1st – 2nd steps away from the bar; average tempo activity of running steps. Conclusion. The results obtained enable identification of lagging and strong points of technical performance and physical fitness of qualified jumpers, and consequently, adjustment of training program for the upcoming training cycle.

Recent studies revealed that amateur athletes, especially young ones, have an increasing tendency of performance-enhancing drugs (PEDs) usage. The aim of this study was to explore PEDs attitudes, beliefs, and practices among young, amateur Croatian athletes. This cross-sectional study using a specially designed questionnaire as a research tool was done during the August 2019 to January 2020 period among a convenient sample of 400 amateur athletes of median age 18 (interquartile range 15 to 21) years. The prevalence of current PEDs usage was 1.3%, while past PEDs usage prevalence was 3.3%. Current PEDs usage was more frequent among young adults (p = 0.048) and athletes playing individual sports (p = 0.001). Athletes who were engaged in sports from one to five years had more permissive attitudes toward PEDs (p < 0.001) as measured by the Performance Enhancement Attitude Scale. Female athletes had more positive beliefs about PEDs usage (p = 0.008). The study did not establish any correlation between current or past PEDs usage and attitudes toward PEDs as well as beliefs about PEDs usage. However, there was a weak positive correlation between attitudes toward PEDs and athletes’ beliefs about PEDs usage (rs = 0.465, p < 0.001). PEDs usage is present among young Croatian amateur athletes. There is a need for interventions directed toward the prevention of PEDs usage in an observed subgroup of athletes.

Calcium is the main mineral that is needed by athletes for bone strength, joint, and muscle contraction during exercise. Strenuous and prolonged exercise will progressively increase calcium requirements. This inadequate calcium intake is having an impact on hypocalcemia and increasing the risk of sports injuries. The purpose of the study was to analyze the effect of calcium supplementation on fitness and health in Tarung Derajat athletes. The research design was experimental (pretest-posttest without control group design). A total of 21 Tarung Derajat athletes, aged 18-25 years, male and female were the subjects. The examination was physical fitness, anthropometric values, and blood pressure to determine the health profile, and blood calcium. The intervention was a calcium tablet, a dose of 1x1000 mg/day, given after dinner, and for 35 days. The results found that the number of female athletes with hypocalcemia decreased by 50%, from 44.44% (before) to 22.22% after calcium therapy. Physical fitness increased (p<0.05), but there was no change in weight (p>0.05), body mass index (BMI) (p>0.05), blood pressure (BP) (p>0.05) ) and calcium levels (p>0.05) after calcium supplementation. Conclusions: supplementation of calcium tablets decreased the amount of hypocalcemia in Tarung Derajat female athletes, increases physical fitness, does not significantly increase calcium levels but otherwise does not affect anthropometry (body weight and body mass index), and blood pressure in Tarung Derajat athletes.
