ABSTRACT Introduction: Overtraining in football is caused by an imbalance between body load, stress, and recovery. High-volume non-scientific physical training and continuous high-intensity football matches are often the main reasons for the overtraining of athletes. Objective: This article explores the characteristics of the changes in physical function of football players during a complete training cycle. Methods: We use experimental methods to analyze the changes in the physical load characteristics of football players during high-intensity training. Results: Creatine kinase, urea nitrogen, and oxygen transport indicators did not change significantly during football training. Testosterone and cortisol will gradually increase with an increase of exercise load. Conclusion: In football training, we need to reasonably arrange the total exercise volume, exercise intensity, and exercise interval time of the athletes according to the trainer’s physical adaptability and athletic ability, supplemented with nutrition and enthusiasm recovery measures. These methods can improve or enhance the physical function of football players. Level of evidence II; Therapeutic studies - investigation of treatment results.

ABSTRACT Introduction: Physical exercise is an important factor in regulating energy balance and body composition. Exercise itself is a kind of body stress. It involves the central nervous system, cardiovascular, respiratory, endocrine, and other systems. Sports have various effects on the hormones in adolescent height development. Objective: This article analyzes the effects of different time and load exercise training on the levels of serum testosterone, free testosterone, and cortisol in young athletes. Methods: The athletes’ blood samples were collected at the quiet time in the morning before each experiment, immediately after exercise, and at three time intervals the next morning. Then blood testosterone (T), free testosterone (FT), and corticosteroids (C) were measured. Results: One-time and one-day high-volume training can cause a decrease in serum testosterone and free testosterone levels and an increase in cortisol hormones in young athletes. The testosterone level of young athletes rises immediately after exercise. Conclusion: Hormonal changes after physical exercise provide a scientific basis for athlete exercise load prediction and exercise plan formulation.

ABSTRACT Introduction: Sports muscle injury is a common phenomenon in sports, and most of it is caused by intense exercise done for a long time. Objective: The effect of high intensity mode (HI) speed endurance training on the muscle injury of athletes. Methods: 14 sprinters were recruited; the muscle injury indexes of the subjects were tested 15 min before and 24 h, 48 h and 72 h after speed endurance training in HV mode and HI mode (high volume mode and high intensity mode, respectively). Results: The results of this study showed that both high amount and HI mode speed endurance training caused a certain degree of injury to the subjects’ muscles, but the injury caused by HI mode speed endurance training to the muscles was more serious than that caused by high amount (P < 0.05). Conclusions: HI mode speed endurance training causes a certain degree of injury to the subjects’ muscle, but it causes more serious injury than high volume mode speed endurance training.

High Intensity Interval

Growing research suggests that high-intensity interval training (HIIT) is a time-efficient exercise strategy to improve cardiorespiratory and metabolic health. “All out” HIIT models such as Wingate-type exercise are particularly effective, but this type of training may not be safe, tolerable or practical for many individuals. Recent studies, however, have revealed the potential for other models of HIIT, which may be more feasible but are still time-efficient, to stimulate adaptations similar to more demanding low-volume HIIT models and high-volume endurance-type training. As little as 3 HIIT sessions per week, involving ≤10 min of intense exercise within a time commitment of ≤30 min per session, including warm-up, recovery between intervals and cool down, has been shown to improve aerobic capacity, skeletal muscle oxidative capacity, exercise tolerance and markers of disease risk after only a few weeks in both healthy individuals and people with cardiometabolic disorders. Additional research is warranted, as studies conducted have been relatively short-term, with a limited number of measurements performed on small groups of subjects. However, given that “lack of time” remains one of the most commonly cited barriers to regular exercise participation, low-volume HIIT is a time-efficient exercise strategy that warrants consideration by health practitioners and fitness professionals.

Abstract The aim of this study was to compare the kinematic characteristics of tennis matches between red clay and hard courts in young tennis players. Eight young tennis players performed two tennis matches on different court surfaces. The match activities were monitored using GPS units. The distance covered in different velocity ranges and the number of accelerations were analyzed. The paired t test and inference based on magnitudes were used to compare the match physical performance between groups. The total distance (24% of difference), high-intensity running distance (15 - 18 km/h) (30% of difference), the number of high-intensity activities (44% of difference), the body load (1% of difference), and accelerations >1.5 g (1.5-2 g and >2 g 7.8 and 8.1 % of difference, respectively) were significantly greater in clay court than hard court matches (p < 0.05). Matches played on the red clay court required players to cover more total and high-intensity running distances and engage in more high-intensity activities than the matches played on the hard court. Finally, on the clay court the body load and the number of accelerations performed (>1.5 g) were possibly higher than on the hard court.

Summary Introduction: Practical and portable the personal stereos if had become almost indispensable accessories in the day the day. Studies disclose that the portable players of music can cause auditory damages in the long run for who hear music in high volume for a drawn out time. Objective: to verify the prevalence of auditory symptoms in users of amplified players and to know its habits of use Method: Observational prospective study of transversal cut carried through in three institutions of education of the city of Salvador BA, being two of public net and one of the private net. 400 students had answered to the questionnaire, of both the sex, between 14 and 30 years that had related the habit to use personal stereos. Results: The symptoms most prevalent had been hyperacusis (43.5%), auricular fullness (30.5%) and humming (27.5), being that the humming is the symptom most present in the population youngest. How much to the daily habits: 62.3% frequent use, 57% in raised intensities, 34% in drawn out periods. An inverse relation between exposition time was verified and the band of age (p = 0,000) and direct with the prevalence of the humming. Conclusion: Although to admit to have knowledge on the damages that the exposition the sound of high intensity can cause the hearing, the daily habits of the young evidence the inadequate use of the portable stereos characterized by long periods of exposition, raised intensities, frequent use and preference for the insertion phones. The high prevalence of symptoms after the use suggests a bigger risk for the hearing of these young.

ABSTRACT Introduction: The study and collection of athletes’ heart function index parameters and the correct and reasonable evaluation of body functions can effectively adjust training plans and avoid athletes’ bodily exhaustion. Objective: To study the diagnosis of myocardial injury by cardiovascular monitoring in athletes from two aspects: extraction of characteristic parameters of heart function and research of signal processing. Methods: The heart function intelligent evaluation algorithm was studied by using multi-source information fusion, and embedded technology; miniature sensors were used as well. Results: The incidence of severe ventricular arrhythmia was lower in both groups. The incidence of sinus arrhythmia and intermittent second degree I atrioventricular block in the high-intensity group was significantly higher than that in the control group. The number of atrial and ventricular premature beats was lower in the control group, but increased significantly in the high-intensity group. Conclusions: This study applied the theory of multi-source information fusion to carry out representative research on the intelligent monitoring and evaluation of the heart function of elite athletes, centering on the application requirements of the heart function monitoring of elite athletes.

Football 7 and Football 9 are worldwide famous – sport-game for children and adolescents from 7 to 12 Years. In this relation, the need for an in-depth analysis of the football training - in particular with the younger football players in our country - is of interest and current, by seeking new forms and diversifying the activities in the physical education and sports lessons that are in line with the national traditions, socio-economic conditions and leading European practices. Such an opportunity is provided by the gaming approach that seeks to explore, summarize and propose effective solutions to optimize football education. This study aims to identify and compare changes in indicators that inform on the specific preparation of pupils from the initial stage of primary education after applying a gaming approach to football education. After the end of the experimental period under the influence of normal biological development and under the influence of the applied gameplay approach with the students from the experimental group, there were significant positive changes. The developed gaming approach should be offered as an opportunity to diversify the organization of the physical education and sports training process in the initial stage of the primary education.

The increase in players' performance due to the development of effort capacity has become more and more dominant in recent years, because of the ever-increasing contribution of science. The maximization of the connection between the physical, technical and tactical aspects of the soccer game focuses on designing the training session and on the clear justifications of the specific methods used in the modern game. To comply with a particular technical or tactical game system or plan, players must be able to physically carry out the requirements of this approach. If traditional football training used to focus primarily on player's technical and tactical development, to the detriment of physical training, the people involved in the educational processes have changed this with the intention of giving physical training a greater time span.
