Comparative study on the validity of monitoring test indexes of healthy fitness cardiopulmonary track and field sensor

With the continuous increase in social pressure and people’s higher urgency for physical health, the concept of healthy physical fitness has become more and more important and prominent. However, the research and standards for the validity of the health fitness monitoring test indicators have not been determined. In order to compare the validity of the health fitness test indicators, we adopt the cardiopulmonary track and field sensor technology to monitor the health fitness cardiopulmonary track and field sensor. A comparative study on the validity of test indicators, mainly to test the rationality of the cardiopulmonary endurance evaluation indicators of healthy physical fitness, and to carry out a new design of the concept of healthy physical fitness in track and field teaching, so that it is more inclined to improve the healthy physical fitness of athletes fitness. Research data shows that the average absolute value of the athlete’s maximum oxygen consumption is 2.51 L/min, the highest value is 3.96 L/min, and the lowest is 2.03 L/min. The average value of the absolute maximum oxygen consumption of girls is 1.79 L/min, the highest value is 2.89 L/min, and the minimum is 1.51 L/min. From these data, we can know that compared with traditional cardiopulmonary monitoring methods, the sensor monitoring studied in this paper has higher accuracy and wider application range. The peak cardiopulmonary power of athletes’ cardiopulmonary function detection using this method is closer to the actual value, while for the peak cardiopulmonary power detected by traditional methods, there is a big difference between the power and the actual value. For different athletes, the advantages of the algorithm in this paper are more obvious, indicating that the method in this paper has a higher detection accuracy for the cardiopulmonary function test of athletes during aerobic training.

Epidemiology of overuse injuries in U.S. secondary school athletics from 2014–2015 to 2018–2019 using the National Athletic Treatment, Injury and Outcomes Network Surveillance Program.

ABSTRACT Context: With 8 million annual participants in the United States, the epidemiology of sports-related injuries in high school athletics has garnered significant interest. The most recent studies examining overuse injury rates in high school sports reported data from 2012–2013 and therefore may not reflect current overuse injury rates in high school sports. Objective: To 1) to determine overuse time-loss (TL) and non-time-loss (NTL) injury rates among high school student athletes using NATION-SP data collected from 2014–2015 to 2018–2019 and 2) compare overuse injury rates based on student-athlete gender defined by sport, sport, and injury location. Design: Descriptive epidemiology study. Setting: Online injury surveillance from 211 high schools (345 individual years of high school data). Patients or Other Participants: Athletes participating in secondary school-sponsored boys' and girls' sports. Main Outcome Measures: Boys' and girls' overuse injury data from the National Athletic Treatment, Injury and Outcomes Network Surveillance Program (NATION-SP) from the 2014–2015 to 2018–2019 school years were analyzed. Overuse injuries were identified using a combination of reported injury mechanism and diagnosis. TL injuries resulted in restriction from participation beyond the day of injury; a NTL injury did not result in restriction from participation beyond the day of injury or lost no time due to the injury. Injury counts, rates, and rate ratios (IRRs) were reported with 95% confidence intervals (CIs). Results: The overall overuse injury rate was 5.3/10,000 AEs (95%CI=5.1, 5.7), the NTL overuse injury rate was 3.4/10,000 AEs (95%CI=3.1, 3.6), and the TL overuse injury rate was 2.0/10,000 AEs (95%CI=1.8, 2.2). The overuse injury rate was greater in girls' sports compared to boys' sports (IRR=1.9; 95%CI=1.7, 2.1). The highest rates of overuse injury were reported in girls' cross-country (19.2/10,000 AEs; 95%CI=15.0, 24.2), girls' track and field (16.0/10,000 AEs; 95%CI=13.5, 18.8), and girls' field hockey (15.1/10,000 AEs; 95%CI=10.2, 21.6). Overuse injury rates were highest for the lower extremity compared to the upper extremity (IRR=5.7; 95%CI=4.9, 6.7) and for the lower extremity compared to the trunk and spine (IRR=8.9; 95%CI=7.3, 10.8). Conclusions: Awareness of overuse injury risk as well as prevention and intervention recommendations are necessary and should be specifically targeted towards cross-country, field hockey, and track and field athletes.

The Physical Development and Physical Preparedness of the Students at the Age of 17-20 Years Old Who Go in for Track and Field

The impact of regular track and field trainings on student’s physical development and physical preparedness have been studied in the work. The study was conducted in the Kyrgyz-Turkish Manas University. İn total, 64 students at the age of 17-20 years have participated into the study. Applied methods: anthropometry, physiometry, the Stange-Hench tests. Sports and pedagogical control tests (on flexibility, strength, speed, endurance and agility) have been used as well.While evaluating students’ physical development, the second study of both ‘Sports’ and ‘Initial’ groups has revealed the high indices among boys according to the following criteria: body height and weight, chest bulk, vital capacity, chest excursion and the Stange-Hench tests. According to the heart rate criterion, the indices of the “Sports” group were reliably higher than those of the “Initial” group (P < 0.05). During the comparison of the second study results of girls’ physical development, more reliable distinctions have been found out (P < 0.05). When the physical development indices were under the study, the second examination exposed and proved that the flexibility of boys from ‘Sports’ group being higher on 7.1 cm (P < 0.05).The experimental materials provided in this article gave an opportunity for concluding that systematic track and field trainings had had a positive impact on the physical development indices, to be precise on the functional condition and physical preparedness level of boys and girls at the age 17-20 years old.

Athletes’ Physical Performance in the System of the Sports Medicine Technologies Effectiveness Evaluation

Aim. To determine the effectiveness of the specific loading testing use in assessing the athletes’ physical performance. Material and methods. We present a post-hoc analysis of data from specific and nonspecific loading testing (bicycle ergometer, treadmill, rowing ergometer, and ski treadmill) of 23 oarsmen athletes (13 male (mean age 25.85±0.88 years) and 10 female (mean age 22.90±1.20 years); 125 track and field athletes (75 male athletes (mean age 24.74±0.91) and 50 female athletes (mean age 23.81±1.35)), 38 ski athletes (22 male athletes (mean age 21.3±2.4) and 16 female athletes (mean age 19.6±1.8)). Results and discussion. When assessing the physical performance of track and field athletes of various positions using a bicycle ergometer and a treadmill, the maximum oxygen consumption (MOC) parameter for throwers and jumpers was in the range of 29-55 ml/min/kg (it is more appropriate to use a statoergometer), for runners – 39-75 ml/min/kg (testing on a treadmill is preferable). The greatest efficiency and physiological validity was obtained by load testing using a rowing ergometer for rowing athletes and a ski roller treadmill for athletes of ski sports (the ratio of heart rate at the anaerobic metabolism threshold level to the heart rate “on failure” is ~ 97%). With bicycle ergometry, low values of MOC were obtained in athletes training for endurance, and, including on the treadmill, in athletes with the main strength load and implies the work of the muscles of the upper shoulder girdle and back. The functional and reserve capabilities of the athlete are not reflected in the data obtained that makes impossible to judge the level of his/her functional readiness. Conclusion. Sports medicine technologies reflecting the dynamic characteristics of athletes’ physical performance should be evaluated from the point of view of informativeness and efficiency of their application depending on the type of sport. Conclusion about the effectiveness of sports medicine technologies should be made considering the results of the functional and physical performance testing under the exertion, specific to a particular sport.

Design and Research of a Foul Detector for Long Jump Stepping on a Jump Line Based on the Wireless Sensor Network

In view of the problems of the judgment of the referee in international long jump competition, such as the omission and wrong judgment, a real-time, accurate, and effective detection instrument is designed. The sensor carried on the athlete is used as the detection element of the foul, which ensures the accuracy and timely information acquisition and effectively prevents the wrong judgment and the missed judgment. The system data is transmitted by the wireless sensor network, which is highly safe and reliable. The experimental results show that compared with the traditional artificial judgment results, the long jump crossover line foul detector based on the wireless sensor network can realize the accurate detection of the number of fouls. The judgment error is lower than the requirements of track and field rules for detection tools, which has great practical value and economic significance.

Justification of the choice of indicators for assessing load hypoxia in humans and laboratory animals

In a study on healthy athletes of the track and field profile, it was shown that the hypoxia of physical activity is most fully reflected by the indicator of specific oxygen debt (maximum oxygen debt divided by 1000 J of work performed). When simulating load hypoxia in laboratory animals, direct registration of the arising oxygen debt is technically difficult to implement, and its indirect signs may be a decrease in peripheral blood saturation, excessive tachycardia, and hyperlactatemia of the post-load period. Key words: hypoxia of physical activity, oxygen debt, athletes, laboratory animals, blood lactate, physical activity.
