In sport sailing, there are three fundamental pillars of performance for dinghy sailors (physical condition, cognitive ability and equipment). One of the decisive moments in a single-handed dinghy race is sailing upwind, as it requires a high physical demand from the sailors to keep the boat flat and make the best decisions according to the tactical conditions of the race. The objective of the research is (i) to analyze the performance of elite sailors on the hiking position in a dynamic virtual sailing situation and (ii) to measure the lower body muscle fatigue in the hiking action. The sample consisted of 10 sailors from the Ilca sailing class and belonging to the Olympic teams of the Norwegian, Mexican and Spanish national teams, 6 of them men (Mage=31.67, SDage=6.861) and 4 women, (Mage=30.50, SDage=4.655). The fatigue protocol consisted of a static test and a dynamic test of the sac body position. Both tests measure the sailors’ effort up to extreme fatigue or loss of position. The test was performed on the vSail-Trainer® sailing simulator, which allows to reproduce real sailing conditions and displays data on boat control variables. The results obtained show statistically significant differences between the group of women and men on boat speed (P=0.039), distance sailed (P<0.001) and hiking effort (P=0.002). There are statistically significant differences in lower body power pre and post fatigue test. This does not lead to the conclusion that the simulator is a valid tool to assess fatigue specifically in Ilca class sailors.

It is our contention that Aikido may have sufficient support for its use in complementary therapies in the field of clinical treatment. However, as far as we are aware, no extensive scientific studies highlighting the application of Aikido as a psychosomatic therapy in the field of psychological behavioural disorders has been carried out. Our aim here was to conduct a systematic review of scientific studies associated with the possible psychosomatic benefits of Aikido practice and to examine whether there is any theoretical basis for this psychosomatic health connection. In terms of methodology, a systematic review of published scientific literature on health and Aikido was conducted in adherence with PRISMA guidelines. Three aspects of the application of Aikido were identified, one corresponding to phases more susceptible to psycho-emotional instability such as during the period of adolescence; another aspect related to the treatment of overcoming trauma in subjects with post-traumatic stress disorder and the final aspect related to the improvements as a result of the practical intervention of mindfulness. It is evident from our review, that the treatment of Aikido as a discipline with psychotherapeutic potential requires further expert analysis from a cross-disciplinary and interdisciplinary perspective, which would involve establishing a suitable intervention model in order to attain a deeper understanding of the discipline of Aikido. Moreover, a mastery of the field of psychology and psychiatry is required to understand the internal cognitive processes of the subjects studied.

Introduction and objectives: The SARS-CoV-2 infection appears to cause functional impairment of cardiopulmonary performance in many athletes. We studied the post-COVID-19 impact on the cardiopulmonary system, through the maximal ergospirometry test, in elite professional soccer players. Material and method: The sample consisted of 10 AFA (Argentine Football Association) first division soccer players, who underwent pre and post COVID-19 infection maximal oxygen uptake (VO2max) tests. The variables analyzed were absolute and relative VO2max, maximal aerobic speed (MAS), first ventilatory threshold (VT1), second ventilatory threshold (VT2), maximal heart rate (HRmax) and respiratory exercise ratio (RER). Results: The mean age was 22.4 ± 6.9 years, body mass 71.5 ± 7.1 kg and height 176.2 ± 6.9 cm. Post COVID-19 subjects significantly decreased VO2 VT2 by 18% (P = 0.028) and RER significantly decreased by 5% (P = 0.02). HRmax was the only variable that significantly increased post COVID-19 by 1.8% (P = 0.04). No significant changes was observed in body mass 71.5 ± 7.1 vs 73.9 ± 7.4 (P< 0.118), VO2max 61.7 ± 5.2 vs 59.0 ± 5.1 ml·kg·min-1 (P<0,213), MAS 18.7 ± 0.9 vs 18.6 ± 0.5 km·h-1 (P<0,739), VO2VT1 39.2 ± 4.0 vs 37.8 ± 4.3 ml·kg·min-1 (P<0.460), speed al VT1 11.6 ± 0.5 vs 11.8 ± 0.6 (P <0.480) and other variables. Conclusion: It seems reasonable and safe to evaluate athletes after SARS-CoV-2 infection with ergospirometry to ensure health conditions and trainability. In this type of athletes (elite soccer players), the use of the second ventilatory threshold (VT2) can be used as a strategy to observe post-COVID-19 changes. The decrease found may be related more to the cessation of training than to cardiopulmonary damage.
简介和目的:在许多运动员中，SARS-CoV-2感染似乎会导致心肺功能障碍。我们通过最大肺活量测定法研究了新型冠状病毒肺炎后对优秀职业足球运动员心肺系统的影响。材料和方法:样本由10名AFA(阿根廷足球协会)甲级足球运动员组成，他们在COVID-19感染前后进行了最大摄氧量(VO2max)测试。分析变量为绝对VO2max和相对VO2max、最大有氧速度(MAS)、第一呼吸阈值(VT1)、第二呼吸阈值(VT2)、最大心率(HRmax)和呼吸运动比(RER)。结果:平均年龄22.4±6.9岁，体重71.5±7.1 kg，身高176.2±6.9 cm。新冠肺炎后患者VO2 VT2显著降低18% (P = 0.028)， RER显著降低5% (P = 0.02)。HRmax是唯一显著增加1.8%的变量(P = 0.04)。体重(71.5±7.1 vs 73.9±7.4)无显著变化(P<0.118)， VO2max 61.7±5.2 vs 59.0±5.1 ml·kg·min-1 (P< 0.213)， MAS 18.7±0.9 vs 18.6±0.5 km·h-1 (P< 0.739)， VO2VT1 39.2±4.0 vs 37.8±4.3 ml·kg·min-1 (P<0.460)，速度VT1 11.6±0.5 vs 11.8±0.6 (P< 0.480)等变量。结论:用肺活量测定法评价运动员SARS-CoV-2感染后的健康状况和可训练性是合理和安全的。在这类运动员(精英足球运动员)中，使用第二通气量阈值(VT2)可作为观察covid -19后变化的策略。这种下降可能更多地与停止训练有关，而不是与心肺损伤有关。

Objective: To evaluate adductor strength and groin function in high level rink hockey players and its relationship with groin pain in the previous season. Material and method: A cross-sectional study was performed where hip/groin strength and function was assessed via 5 seconds Squeeze Test and Hip and Groin Ouctome Score in 11 high level rink hockey players. Results: Overall prevalence for groin pain was 81.8% (54% of the participants suffered groin pain during the previous season), and 18.2% suffered time-loss groin pain. Mean strength in the 5SST was 254.68N (3.25Nm/Kg) and HAGOS questionnaire reached 90/100 points in the whole sample. Similar adductor strength values were observed between healthy athletes and previously injured who suffered time-loss groin pain (P=0.261-0.948; g: 0.04-0.85). Statistically significant differences were found for the following HAGOS subscales: Pain, function, sports and recreational activities, and quality of life between groups (P=0.005-0.042; g: 0.34-2.65; r: 0.3-0.61). Conclusion: More than a half of the participants suffered groin pain, of which one third suffered time-loss groin pain. Function assessed via HAGOS seems to be the main proxy that discriminates between groups. Medical staff should implement this questionnaire to detect and avoid the progression of this injury

Introduction: Soccer referees need excellent conditioning to withstand the physical and psychological demands of games. Objective: To compare the hemodynamic variables, speed, cadence, and distance coursed of referees during soccer games of series A and B in Rio de Janeiro, Brazil. Material and method: The total number of decisions made during the 10 soccer matches evaluated was 1,224 observable decisions of 10 professional Soccer referees (one per soccer match: 5 in series A and 5 in series B). We used a frequency meter (Polar, model V800, PolarFlow software) and video footage of the games (Sony, model PXW-Z150, 4K). The moments considered were: the decision, 15 seconds that preceded it, and the period from the beginning of each stage to each decision. Were studied the hemodynamic [average heat rate (mean HR), maximum heart rate (HRmax), and minimum heart rate (HRmin)] and motion variables [average speed (Vmed), maximum speed (Vmax), average cadence (cadencemed), maximum cadence (cadencemax), minimum cadence (cadencemin), and distance covered]. Descriptive measures were used to present the results of the variables studied and the Student’s T-Test for independent samples to test the study hypotheses. The significance level was set at 95% (P <0.05). Results: The matches of series A had a greater number of interventions and greater hemodynamic load at the exact moment of the decision than those of series B. significantly (P <0.05): mean HR, HRmax, HRmin, Vmax, Cadencemed, and Cadencemax in series A were higher compared to series B. In the 15 seconds before the decisions: mean HR, HRmax, and HRmin in series A were higher than in series B, and Vmed in series B was higher in relation to series A. At the exact moment of the decisions: mean HR in series A was higher in relation to series B. Conclusion: Referees’ interventions are generally carried out under high hemodynamic pressure. The matches played in the A series require a higher number of interventions and hemodynamic intensity than the matches in the series B under high hemodynamic pressure, other psychological factors may play a role; however, this needs to be studied in greater depth.

Introduction: Determining the body composition and somatotype in sport talents provides a useful reference to improve the trajectory toward high-level competition. Objective: The aim of this study is to determine the body composition and somatotype by discipline of children and adolescents of both genders in the sport talent development program at the Regional Training Center. Material and method: Seventy-two subjects participated (29 females, 15.9 ± 2.0 years; 43 males, 15.9 ± 2.3 years) from the disciplines of athletics, cycling, judo, karate, and table tennis. a) Baseline measurements: weight, height, and body mass index (BMI); b) Body masses by fractioning into five components (in %): muscle, fat, bone, residual and skin, using Kerr’s method and c) Somatotype, according to the model proposed by Heath and Carter were performed. Results: Females have a higher percentage of fat mass than males. Exactly the opposite occurs with muscle mass, where males present a higher percentage than females, with the exception of table tennis. Regarding residual mass, males present higher values in all the disciplines. The males were classified as endo-mesomorphs, except for those in athletics, who were classified as ecto-mesomorphs, while the females from athletics and table tennis were classified as central, those from cycling and judo as endomorph–mesomorphs, and those from karate as meso-endomorphs. Conclusion: Through a two-dimensional contrast of the somatotype of CER athletes and that of adult athletes at the High Performance Center in Chile, it was determined that both groups are different, indicating that CER athletes do not yet meet the structural requirements necessary for a trajectory to high-level competition, suggesting that training modifications be considered to get closer to the ideal somatotype.

Objective: The aim of this study is to determine the body composition and somatotype by discipline of children and adolescents of both genders in the sport talent development program at the Regional Training Center. Material and method: Seventy-two subjects participated (29 females, 15.9 ± 2.0 years; 43 males, 15.9 ± 2.3 years) from the disciplines of athletics, cycling, judo, karate, and table tennis. a) Baseline measurements: weight, height, and body mass index (BMI); b) Body masses by fractioning into five components (in %): muscle, fat, bone, residual and skin, using Kerr’s method and c) Somatotype, according to the model proposed by Heath and Carter were performed. Results: Females have a higher percentage of fat mass than males. Exactly the opposite occurs with muscle mass, where males present a higher percentage than females, with the exception of table tennis. Regarding residual mass, males present higher values in all the disciplines. The males were classified as endo-mesomorphs, except for those in athletics, who were classified as ecto-mesomorphs, while the females from athletics and table tennis were classified as central, those from cycling and judo as endomorph–mesomorphs, and those from karate as meso-endomorphs.

Flamenco dance is a performing art which is based on footwork technique where the foot and ankle play an important role. The objective of this study was to investigate the effect of ankle active range of motion on external load and its efficacy as a predictor during a flamenco footwork technique, with consideration of accelerometer positions and dance proficiency. Twelve flamenco dancers composed of 6 professional and 6 amateurs participated voluntarily in this study for whom no significant differences were detected regarding age, mass or height. Participants completed a 15-second Zap-3 footwork test at a speed of 160 bpm (beats per minute), 180 bpm and as fast as they could. Triaxial accelerometers were positioned at the dominant ankle, 5th lumbar vertebrae and 7th cervical vertebrae to calculate accumulated PlayerLoad and uniaxial PlayerLoad of the 3 planes (anteroposterior, mediolateral and vertical) for each speed level. Percentage contributions were also calculated. The effect of dorsiflexion on the external load of the dominant ankle of both professional and amateur dancers existed only in the anteroposterior axis while dorsiflexion was related to the external load at the 7th cervical vertebrae and only amateurs were affected. Plantarflexion only affected the uniaxial contribution of the vertical-axis of professional dancers. These programs would be applied to develop a technique feedback system for the flamenco dancer to follow their own model with respect to the ideal. This would allow intervention in the prevention of overuse injuries in flamenco dance artists

Objective: To know the surgeon’s decision making on the choice of graft in anterior cruciate ligament (ACL) reconstruction surgery according to the sport practiced by the patient. Material and method: An online survey was conducted through the Spanish Society of Sports Traumatology (SETRADE) and the European Society for Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA). A descriptive analysis of the sample was performed, and an analysis of the main reason for the choice of plasty was carried out stratifying the sample into different groups. Results: 83 surgeons responded to the survey, 71 members of SETRADE and 12 of ESSKA. The mean number of ACL reconstruction performed per year per respondent was 56 (1-220). For 86.7% of the respondents, sport influenced the decision on the type of graft to be used, the main reason being the biomechanical properties of the plasty (49.4%). The mean agreement in the type of graft to be used in each sport studied was 58.29% (71.1%-38.6%). The highest concordance in the plasty of choice occurred in cycling, with respondents using hamstrings in 71.1% of cases. The sports with the least concordance were wrestling and skiing. There were no statistically significant differences in the reason for choosing plasty. Conclusions: The survey was conducted by a significant number of surgeons with experience in ACL surgery, with biomechanical properties being the main reason for choosing which graft to use. Most of them were influenced in this decision by the type of sport practiced. The authors recommend the handling of at least 2 plasties for primary ACL reconstructions and to individualize each case considering the type of sport in the selection of the graft.
