태권도 국가대표 선수들의 경기력 요인에 대한 탐색적 접근

The purpose of this study was to explore the performance factors of national taekwondo players and to present improvement and support measures for the factors. Research participants were seven female national team athletes participating in the 2022 World Taekwondo Championships, we used photovocie, participatory action research strategy. The process of photo-voice was categorized in the order of factors of the national Taekwondo players were categorized into internal and external factors. Sub-topics of the inner factors were ‘mirror that shines on me’, ‘fight against weight’, ‘time alone’, and ‘routine that protects me’, and the outer factors were categorized into ‘my own endorphins’, ‘fatal encounters’, and ‘growth in pain’. Based on the results of this study, we discussed on inherent performance factors and offered some suggestions for future improvement and support.

Practical Efficacy of Prior Checks on Athletes’ Medication Use for the Prevention of Unintentional Doping

Background: Athletes are subjected to disciplinary action for even unintentional doping. This study aimed to clarify the effectiveness of prior checks on athletes’ drug regimens by medical personnel with knowledge of anti-doping to prevent unintentional doping. Methods: This is a retrospective evaluation of the inquiries to the Anti-Doping Committee by the Japan Table Tennis Association national team athletes and athlete support personnel between 2011 and 2019 regarding whether the drug in question was permitted and whether it contained any prohibited substance. Discrete evaluations were performed for ethical and over-the-counter drugs, in addition to the evaluation of all drugs. Additionally, we evaluated the drugs according to therapeutic category and World Anti-Doping Agency’s classification. Results: Overall, 85/1238 (6.9%) ethical drugs, 49/259 (18.9%) over-the-counter drugs and 134/1497 (9.0%) total drugs were considered as not allowed for use. The proportion of over-the-counter drugs judged as not allowed for use was higher than that of ethical drugs (p < 0.001). When tabulating the drugs not allowed for use in the therapeutic category, numerous prohibited substances were identified in adrenal hormone preparations, Kampo products, synthetic narcotics, antitussives, antihemorrhoidals, and bronchodilators among ethical drugs and in cold remedies, gastrointestinal drugs, and antitussives and expectorants among over-the-counter drugs. Conclusions: Of the ethical and over-the-counter drugs that elite athletes wanted to use, approximately 10% were not allowed because of the risk of unintentional doping. These results suggest that conducting prior checks of the athletes’ drug regimens by medical personnel with anti-doping knowledge are effective measures to prevent unintentional doping.

The impact of the COVID-19 pandemic on Canadian national team athletes' mental performance and mental health: The perspectives of mental performance consultants and mental health practitioners.

The COVID-19 global pandemic has led to significant disruptions in the lives of high-performance athletes, including the postponement of the Tokyo Olympic and Paralympic Games, the cancellation of many international and national competitions, and drastic changes in athletes' daily training environment. The purpose of this research was to examine the interplay between the mental health and mental performance of Canadian national team athletes and the impact of the COVID-19 pandemic on these variables from the perspective of mental performance consultants and mental health practitioners. Twelve individuals working in these roles with national team athletes participated in focus groups and interviews during the second wave of the COVID-19 pandemic in Canada. Findings from the inductive reflexive thematic analysis revealed three main themes: (a) factors impacting athlete mental health (i.e., social and environmental, psychological, and public health restrictions), (b) consequences of COVID-19 for athletes (low mood symptoms, anxiety and stress symptoms, maladaptive behaviors, time for life outside of sport, rest, and recovery), and (c) impact of the pandemic on practitioners (roles, preparation and resources, gaps, and well-being). Interestingly, athletes with prior good mental performance skills were perceived to be more equipped to cope with challenges related to the pandemic, which concurrently seemed to facilitate good mental health throughout the pandemic. Furthermore, even though the pandemic had several debilitative consequences on athletes' mental health, it imposed a break from training and competition that allowed them to rest and enjoy their life outside of sport. Finally, participants discussed the need for more mental health resources and better access to practitioners supporting mental performance and mental health in the Canadian sport system.

Differences in lung function, bronchial hyperresponsiveness and respiratory health between elite athletes competing in different sports

ABSTRACT The aim of this study was to examine lung function, bronchial hyperresponsiveness (BHR) and exercise-induced respiratory symptoms in elite athletes performing different sports. Norwegian national-team athletes (30 swimmers, 32 cross-country skiers, 16 speed-skaters, 11 rowers/paddlers, 17 handball players and 23 soccer players) completed a validated questionnaire, measured exhaled nitric oxide (FENO), spirometry, methacholine provocation (PD20met) and skin prick test. Three cut-off levels defined BHR; i.e. PD20met ≤2 µmol, ≤4 µmol and ≤8 µmol. Mean forced vital capacity (FVC) was highest in swimmers (Mean z-score[95%CI] = 1.16 [0.80, 1.51]), and close to or higher than reference values according to the Global Lung Initiative equation, across all sports. Mean forced expiratory volume in 1 s (FEV1) was higher than reference values in swimmers (0.48 [0.13, 0.84]), and ball game athletes (0.69 [0.41, 0.97]). Mean forced expiratory flow between 25 and 75% of FVC (FEF25-75), and/or FEV1/FVC were lower than reference values in all endurance groups. BHR defined by ≤2 and ≤8 µmol methacholine was observed in respectively 50%–87% of swimmers, 25%–47% of cross-country skiers, 20%–53% of speed-skaters, 18%–36% of rowers/paddlers, and 0%–17% of the ball game athletes. Exercise-induced symptoms were common in all groups, most frequent in cross-country skiers (88%), swimmers (83%) and speed-skaters (81%). Highlights Swimmers and ball game athletes had higher mean FVC and FEV1 when compared to the reference values predicted by the Global Lung Initiative (GLI) reference equation. Contrasting this, across all sports except ball game athletes, mean FEF25-75 and/or FEV1/FVC were lower than reference values. The prevalence of bronchial hyperresponsiveness (BHR) was high among elite athletes competing in swimming, cross-country skiing, speed skating and rowing/paddling, with swimmers being most affected. The majority of the elite athletes reported exercise-induced respiratory symptoms independent of lung function or BHR.

The Role of Aerobic Capacity and Strength Levels on Wingate Performance and Lactate Concentrations

Background: Blood lactate (La-) is commonly assessed in tests of sport performance. Sports that utilize intermittent high intensity effort, monitoring of La- from previous exercise can be useful to document intensity of effort. Objective: The purpose of this study was to investigate the role La- played during successive Wingate (Win) tests and subsequent anaerobic exercise performance. Method: Well-trained, national team athletes from Jordan (n = 31) volunteered to participate. A quasi-experimental design was utilized to test Win performance and La- concentration. All participants engage in two Win tests with one minute rest between sets. La- was collected at four time points (prior to Win test 1, immediately after Win 1, after Win 2 and after a 10 minute recovery period). Results: Findings from a multiple linear regression model (p = 0.032) showed increased levels of La- accumulation as a predictor to higher power and strength (p = 0.046). Conversely, peak aerobic capacity was a predictor for decreasing La- accumulation over time (p = 0.039), which may suggest faster recovery. Conclusion: Anaerobic athletes who participate in short, high intense bouts of exercise may require high intensity training programs to increase aerobic fitness, power output, and optimal performance. Practical applications include optimizing training programs to reflect competition.

Listening to Athletes' Voices: National Team Athletes' Perspectives on Advancing Safe Sport in Canada.

With increased media scrutiny, public awareness, and research on the prevalence of maltreatment experiences in sport, sport organizations have faced increased pressures to combat unsafe practices in sport. A consequence has been the emergence of the Safe Sport movement whereby organizations including the International Olympic Committee, Safe Sport International, US Center for SafeSport, Sport Canada, and others, have developed policies, initiatives, and education intended to create safer sport environments for all participants. Most of these policies have been implemented using a top-down approach, driven by government officials and sport leaders. However, if safe sport initiatives are to benefit athletes, consideration and incorporation of athletes' perspectives in the development and implementation of initiatives are imperative. The purpose of this study, therefore, was to examine athletes' perspectives on the challenges and recommendations to advancing safe sport. As part of a large-scale survey of current and retired Canadian National Team Athletes' experiences of maltreatment, open-ended questions were asked about athletes' recommendations and considerations for safe sport. Responses to these questions (n = 386) were analyzed using thematic analysis. According to the participants, barriers and challenges to safe sport included emphasizing performance excellence at-all-costs, normalization and complicity of harm, lack of attention to equity, diversity and inclusion, a culture of fear and silence, and a lack of trust in organizations to handle cases of harm. In an effort to advance safe sport, participants recommended prioritizing holistic athlete development, improving and strengthening accountability measures, implementing an independent 3rd party for disclosure, reporting and support, increased attention to equity, diversity and inclusion, stakeholder education, prohibition of sexual relations between athletes and those in positions of power and authority, and adoption of a broader perspective of harms and perpetrators. Findings are interpreted and critiqued in light of previous literature and recommendations for future research and practice are suggested.

Возрастные особенности телосложения спортсменок, специализирующихся в синхронном плавании

Material and methods. The sample of 50 people consisted of female athletes of three age groups: junior (9-10 years old), senior (14-15 years old) and the Russian national team (over 18 years old). In this cross-sectional study, we used total body dimensions (according to V.V. Bunak), body mass components (ac-cording to J. Matiegka’s formulas and bioimpedance method), body proportions (according to P.N. Bashkirov’s method), body shape (by somatoscopy), somatotype (by the Heath-Carter and Shtefko-Ostrovsky) and biological age (by dental and sexual maturity). Results. In terms of physical development, artistic swimmers (girls) do not differ significantly from their peers who do not go in for sports. The body height of the national team athletes is higher than the average values for their gender, and the body weight is lower. Under the influence of training loads in young artistic swimmers, there is a slight decrease in the fat component and an increase in the muscle one. Russian elite artistic swimmers have a lower level of development of adipositythan athletes of the national teams of Ko-rea and Spain. The muscular component of the Russian artistic swimmers may indicate overwork. The analy-sis of the variability of body proportions of artistic swimmers of different age groups testifies to the target-ed selection to the national team in the terms of longitudinal body dimensions. At the present stage of development of artistic swimming, the selection of retardant athletes is taking place. It was revealed that somatotypes with significant mesomorphism prevail in younger and older age groups, while the athletes of the national team belong to the ectomorphic body type with various variations of two other components of the somatotype. Conclusion. The study of morphological indicators made it possible to form an idea of the importance of the somatotype and body proportions for artistic swimming, which, in the combination with other necessary qualities, will increase the efficiency of selection and control of the training process.

A Vision of Macau’s Football through the Symbolic Legacy of the Portuguese Presence

This paper analyses the sociocultural background, and the nature of the cultural legacy of the Portuguese, in the diffusion and promotion of football in Macau. The paper seeks to examine why men’s football in Macau’s remains poorly developed at domestic, regional and international levels. Many factors could explain this lack of development, ranging from the limited degree of organizational specialization inherited from the Portuguese administration, problems regarding implementing rules and tournament organization, the lack of sports facilities, and the tension between the national governing body and the national team athletes. Nevertheless, there has also been some important progress, such as the recruitment of young footballers and the inclusion of local Portuguese talented players. These developments are discussed in a multidisciplinary approach, based on academic literature and harnessing comprehensive documentary analysis derived from official documents and website information of sports associations.

Body shaming as a form of emotional abuse in sport

ABSTRACT In this study, we explored the experiences of body shaming as a form of emotional abuse and the effects of these experiences. The reported findings represent a secondary analysis conducted of data gleaned from a study exploring the long-term effects of emotional abuse of 8 female National Team athletes in aesthetic sports. Semi-structured interviews were conducted with the athletes and analysed from a constructivist lens. The athletes indicated that they experienced negative verbal comments about their bodies, body monitoring, forced restrictions of food and water, public criticism of the body, and punishment when body-related standards were not met. Athletes discussed the effects of these experiences, which included normalisation, social comparison, extreme weight control methods, negative health outcomes, performance decrements, and decreased enjoyment. These findings are interpreted to suggest that the coaches’ actions to monitor and control the athletes’ weight constitute body shaming practices and that body-related shaming should be considered a form of emotional abuse.

Prevalence of Maltreatment Among Canadian National Team Athletes.

This study assessed the prevalence of maltreatment experienced by Canadian National Team athletes. In total, 995 athletes participated in this study, including current athletes and athletes who had retired in the past 10 years. An anonymous online survey was administered, consisting of questions about experiences of psychological, physical, and sexual harm, and neglect, as well as questions about identity characteristics, when the harm was experienced, and who perpetrated the harm. Neglect and psychological harm were most frequently reported, followed by sexual harm and physical harm. Female athletes reported significantly more experiences of all forms of harm. Retired athletes reported significantly more neglect and physical harm. Athletes reportedly experienced more harmful behaviors during their time on the national team than before joining a national team. Coaches were the most common perpetrators of all harms except for sexual harm, which was most frequently perpetrated by peers. This study highlighted the prevalence with which Canadian National Team athletes reportedly experience harmful behaviors in sport, suggesting the need for preventative and intervention initiatives.

Original article: Validity of measuring wheelchair kinematics using one inertial measurement unit during commonly used testing protocols in elite wheelchair court sports

Wheelchair court sports can measure both continuous and discrete wheelchair kinematics using Inertial Measurement Units (IMU) during testing and games. A method involving three IMU (3IMU) shows good validity with motion capture systems, but the hardware cost and the need for multiple sensors may make it a barrier for implementation in a sport context. A method using only one wheel mounted IMU (1IMU) has been developed that may reduce this cost, but further validation is required. This study assessed the validity of 1IMU compared to 3IMU, across a variety of continuous and discrete measurements during common on-court testing protocols, using national team athletes. Subjects recruited from national Wheelchair Basketball and Wheelchair Rugby programs performed a series of sprint, agility, and pivot testing protocols. Continuous wheel speed, frame rotation, and wheelchair speed data as well as a number of important discrete metrics including peak linear and rotational speeds, were compared between 3IMU and 1IMU. Low error (RMSE < 0.15 m s−1) and high linearity (R2 > 0.99) were seen in continuous measurements for wheel speed. Similar observations were made for frame rotational speed (RMSE < 11° s−1 and R2 < 0.97) during continuous measurements. Good to excellent intraclass correlations (ICC) were observed for peak linear speeds (ICC > 0.86) and frame rotational speeds (ICC > 0.94). Overall, 1IMU offers a lower cost solution that provides valid information for pertinent outcomes in wheelchair sports to use in the field.

Prevalence of symptoms of common mental disorders among elite Canadian athletes

IntroductionResearchers have increasingly focused on the mental health of elite athletes. However, there remains a paucity of research on the mental health of elite Canadian athletes, and the prevalence of mental disorders among this population is unknown. PurposeThis study evaluated the prevalence of symptoms of mental health disorders, specifically depression, anxiety, and eating disorders (EDs), among elite Canadian athletes, and identified the relationship between components of the stress process model (stress, social support, coping, and self-esteem) and athletes' symptoms of mental disorders. MethodsCanadian national team athletes who were training for the 2020 Summer Olympic Games completed a survey in December 2019. Data were analyzed using descriptive statistics and bivariate correlations. ResultsCanadian athletes (N = 186) were included in the analytic sample. Based on the descriptive results, 41.4% of athletes met the cut-off criteria for one or more mental disorders. Specifically, 31.7% of athletes reported symptoms of depression, 18.8% reported symptoms of moderate (12.9%) to severe (5.9%) general anxiety, and 8.6% reported scores indicating high risk of an ED. Stress was a statistically significant correlate of depression, anxiety, and EDs. Training load was a statistically significant correlate of depression and anxiety, but not of EDs. Depression, anxiety, and EDs were significantly correlated. DiscussionThis study presents the first data on the prevalence of symptoms of mental disorders among elite Canadian athletes and demonstrates that they may be at an increased risk of experiencing a mental disorder compared to the general population.

Depressive symptoms in Icelandic elite athletes: A prospective examination through the lens of the response styles theory

The aim was to explore depressive symptoms through the response styles theory in Icelandic elite athletes using a longitudinal research design. A total of 79 Icelandic elite and national team athletes were included in the study (M = 23.5, SD = 4.8, age range 18–37, females 75.9%). Higher perceived stress and brooding rumination (maladaptive response to negative mood) independently predicted higher depressive symptom scores over the study period. Athletes who reported higher brooding tendencies in the beginning of the study, were significantly more likely than those reporting lower tendencies, to report higher increases in depressive symptoms when stress levels increased over the study period. The findings supported the validity of exploring individual differences in depressive symptoms through the lens of the response styles theory in the athletes. Future research could explore the relationship between brooding rumination, athletic performance, and mental health issues, and test interventions targeting brooding rumination in athletes.

Utilization of Complementary and Alternative Medicine among Korean Elite Athletes: Current Status and Future Implications.

The objective of the study was to explore the status of usage of complementary and alternative medicine (CAM) among Korean elite athletes. A survey was emailed to all Korean national sports federations recognized by the International Olympic Committee and the Olympic Council of Asia. A total of 705 Korean elite athletes participated in this study. The athletes had to be any of the following to participate in this survey: elite intercollegiate athletes, professional athletes, and national team athletes. 83.3% of the participants stated that they have previously experienced Korean medicine (KM). Compared to the general population in Korea, athletes had more experience (general population = 73.8%). The participants without experience mentioned that they either did not need any KM treatments (39.8%) or lacked information (39.8%) regarding KM treatments. The primary reason for the utilization of KM was the effectiveness of treatments. Therefore, 70.8% of the participants have mentioned recommending KM to others. Generally, athletes are worrisome that the consumption of herbal medicine may not be doping-free; however, it is vital to note that 62% of the participants expressed that prescribed herbal medicine is safe. Overall, this research demonstrates a high prevalence of KM usage by intercollegiate, professional, and national team athletes in Korea. Hence, this study's results may serve as the foundation in future research directions for promoting KM among Korean elite athletes.

Current Predictive Resting Metabolic Rate Equations Are Not Sufficient to Determine Proper Resting Energy Expenditure in Olympic Young Adult National Team Athletes.

Predictive resting metabolic rate (RMR) equations are widely used to determine athletes’ resting energy expenditure (REE). However, it remains unclear whether these predictive RMR equations accurately predict REE in the athletic populations. The purpose of the study was to compare 12 prediction equations (Harris-Benedict, Mifflin, Schofield, Cunningham, Owen, Liu’s, De Lorenzo) with measured RMR in Turkish national team athletes and sedentary controls. A total of 97 participants, 49 athletes (24 females, 25 males), and 48 sedentary (28 females, 20 males), were recruited from Turkey National Olympic Teams at the Ministry of Youth and Sports. RMR was measured using a Fitmate GS (Cosmed, Italy). The results of each 12 prediction formulas were compared with the measured RMR using paired t-test. The Bland-Altman plot was performed to determine the mean bias and limits of agreement between measured and predicted RMRs. Stratification according to sex, the measured RMR was greater in athletes compared to controls. The closest equation to the RMR measured by Fitmate GS was the Harris-Benedict equation in male athletes (mean difference -8.9 (SD 257.5) kcal/day), and Liu’s equation [mean difference -16.7 (SD 195.0) kcal/day] in female athletes. However, the intra-class coefficient (ICC) results indicated that all equations, including Harris-Benedict for male athletes (ICC = 0.524) and Liu’s for female athletes (ICC = 0.575), had a moderate reliability compared to the measured RMR. In sedentary subjects, the closest equation to the measured RMR is the Nelson equation in males, with the lowest RMSE value of 118 kcal/day [mean difference: 10.1 (SD 117.2) kJ/day], whereas, in females, all equations differ significantly from the measured RMR. While Nelson (ICC = 0.790) had good and Owen (ICC = 0.722) and Mifflin (calculated using fat-free mass) (ICC = 0.700) had moderate reliability in males, all predictive equations showed poor reliability in females. The results indicate that the predictive RMR equations failed to accurately predict RMR levels in the participants. Therefore, it may not suitable to use them in determining total energy expenditure.

COVID-19 Pandemisi Sürecinde Elit Sporcularda İzolasyon ve Kontrollü Sosyal Yaşam Dönemlerinin Fiziksel Aktivite ve Kaygı Üzerine Etkisi

Objective: To investigate the effects of pandemic on anxiety and physical activity in elite athletes during isolation and controlled social life. The second purpose of the study was to evaluate whether the effects of isolation and restricted social life were different between genders. Material and Methods: A total of 52 elite athletes (80.2% national team athletes) were included in the study. Isolation and controlled social life periods were analyzed. Athlete's anxiety was evauated with Athlete's Anxiety to Catch the Novel Coronavirus (COVID-19) Scale (AACNCS), coronavirus anxiety was evaluated with Coronavirus Anxiety Scale Short Form (CAS-SF), and physical activity level was eavluated with International Physical Activity Questionnaire Short Form (IPAQ-SF). Results: The study indicated that during the isolation period, the anxiety levels of the athletes [AACNCS Social Anxiety score (p=0.009) and CAS-SF score (p=0.008)] were higher and their physical activity levels [IPAQ-SF total score (p0.05). Conclusion: During the pandemic, the isolation period negatively affected the physical activity and anxiety of elite athletes; however, the return to the social life in a controlled manner resulted in a decrease in anxiety and increase in physical activity. These results show the importance of the correct management of the COVID-19 pandemic for elite athletes.

Countermovement Jump Height in National-Team Athletes of Various Sports: A Framework for Practitioners and Scientists.

To quantify possible differences in countermovement jump height across sport disciplines and sex in national-team athletes. In this cross-sectional study, 588 women (23 [5] y, 66 [8]kg) and 989 men (23 [5]y, 82 [12]kg) from 44 different sport disciplines (including 299 medalists from European Championships, World Championships, and/or Olympic Games) tested a countermovement jump on a force platform at the Norwegian Olympic Training Center between 1995 and 2018. Athletic sprinting showed the highest values among the men (62.7 [4.8]cm) and women (48.4 [6.0]cm), clearly ahead of the long jump/triple jump (mean difference ± 90% CL: 6.5 ± 5.0 and 4.3 ± 4.1; very likely and likely; moderate) and speed skating sprint (11.4 ± 3.1 and 7.5 ± 5.5 cm; most likely and very likely; very large and moderate). These horizontally oriented sports displayed superior results compared with more vertically oriented and powerful sports such as beach volleyball, weightlifting, and ski jumping, both in men (from 2.9 ± 4.7 to 15.6 ± 2.9 cm; small to very large; possibly to most likely) and women (5.9 ± 4.8 to 13.4 ± 3.4 cm; large to very large; very likely to most likely), while endurance sports and precision sports were at the other end of the scale. Overall, the men jumped 33% higher than the women (10.3, ±0.6cm; most likely; large). This study provides practitioners and scientists with useful information regarding the variation in countermovement jump height among national-team athletes within and across sport disciplines.

Gender inequity in media coverage and athletes’ welfare in Nigerian sports: impact of the Nigeria sports policy and African union agenda 2063

Sport is an equalizer is not always a reality as demonstrated by persistent gender inequality in Nigeria. Therefore, investigating gender inequalities in sports remains highly relevant. This study examined gender inequity in media coverage and welfare of national teams in line with Nigeria sports policy and Africa Union Agenda 2063. Twenty female soccer, track, and field athletes with five coaches participated in in-depth interviews. Thematic analysis was employed, and results were presented in verbatim quotes. Participants reported significant pay gaps of close to 80% between male and female national team athletes and significant disparities were reported in welfare. Similar disparities were found on media coverage. Female athletes are perceived as inferior, while many quit or take other nationalities to compete at the highest level. Results show minimal progress in achieving gender equity in Nigerian sports despite the sports policy and African Union Agenda 2063. Therefore, sports governing bodies must demonstrate strong alignments between policy and practice.

Comparing the hand grip power and creatine kinase levels of U-17 judo national team athletes before and after a 6-week strength training

Background and Study Aim. The aim of this study is to compare the hand grip power and creatine kinase levels of male and female U-17 National Team Athletes before and after a 6-week strength training.&#x0D; Material and Methods. 15 female and 15 male U-17 athletes, who previously participated in international competitions, participated in our study. Besides the hand grip power and creatine kinase values, age, height, weight, and BMI (body mass index) values of the athletes were measured before and after the training. As the conclusion of the measurements, the mean age of the female participant athletes was determined as 14,93 years, their mean height was 158,3 cm, and the mean age of the male athletes was 15,73 years, while their mean height was 173,1 cm.&#x0D; Results: As the conclusion of the measurements, it was determined that there were statistically significant differences between the right hand grip power and left hand grip power parameters of male and female participant athletes measured before and after the 6-week training. Moreover, it was determined that there were statistically significant differences between the pre-test and post-test measurements of creatine kinase values of both male and female athletes (p&gt; 0,05).&#x0D; Conclusions. As the conclusion, it was determined that the 6-week strength trainings applied to U-17 Judo National Team athletes caused significant changes in their hand grip power and creatine kinase values. The significant results obtained from our study are considered to be originated from the duration, scope, frequency, severity, and content of the training.
