Hockey Experimental Study on the Characteristics of Different Exercise Load

Data about effects of exercise training in adolescents with intellectual disability (ID) are very limited. This study investigated the effect of 2 different frequencies of the same intensity and total training volume of combined exercise training on indices of body composition, physical fitness, and lipid profile in overweight and obese adolescents with ID. A total of 45 overweight and obese adolescents with ID aged 14-22 years with a total IQ 45-70 received combined exercise training 3 times a week (CET3) for 30 sessions (10 weeks; n = 15), twice a week (CET2) for 30 sessions (15 weeks; n = 15), or no training (10 weeks; n = 15). Groups were matched for age, sex, and education form. Before and after the intervention period, indices of body composition, physical fitness and lipid profile have been evaluated. Compared to the control group, CET3 resulted in a significant improvement of physical fitness, obesity indices, and lipid profile of the participants. Comparing CET2 with CET3, no significantly different evolutions were noticed, except for lower limb strength in favor of exercising 3 times a week. In conclusion, exercising 2 times a week, which is more feasible and practical for participants and guidance, has the same health beneficial effects as 3 times per week in overweight and obese adolescents with ID in short-term training.

In order to thoroughly implement General Secretary General Secretary Xi's important statements on education and sports delivered at the 20th National Congress and the National Education Conference, Southwest Jiaotong University has fully implemented comprehensive physical education courses as part of its deepened sports reform. By utilizing field research, interviews, and mathematical statistics, this study explores the paths and methods for fully implementing physical education courses in the new era of school sports. The research concludes that the integration of in-class and extracurricular activities, the fusion of MOOCs and flipped classrooms, and the combination of information technology with traditional teaching methods constitute effective strategies for implementing comprehensive physical education courses in the new era. First, the integration of physical education classes with the "Sports and Health Supermarket," which includes both physical exercise and sports competitions, is an effective approach to integrating in-class and extracurricular physical education in the new era. This model ensures that learning, practice, and competition are interwoven, providing students with comprehensive opportunities for physical exercise and competition at all levels, thereby fostering the overall development of sports education. Second, the close integration of MOOCs and flipped classrooms addresses the current shortage of physical education teachers in universities. By making sports course content available as MOOCs, students can engage in self-directed learning outside of class, while classroom time is devoted to interactive discussions and practical activities, thereby enhancing both teaching efficiency and quality, and providing more opportunities for students to participate in sports activities. Finally, by implementing these strategies and methods for comprehensive physical education courses, students' physical fitness is significantly improved. The school not only focuses on in-class physical exercises but also actively organizes various sports competitions and activities, encouraging students to participate and thereby enhancing their overall physical and comprehensive fitness.

Holistic Development is a complete educational strategy that aims to develop physical, intellectual, emotional, cognitive, and social abilities to kids. It seeks to enhance these skills in the early stage of life, which will prepare them to meet the challenges and difficulties of daily life in the future. In this modern century there are main four domains in community development i.e. communication, collaboration, critical thinking and creative thinking. Community development is a holistic approach and an organized effort initiated to assist a group of people in a community to lead a better lifestyle. As the term suggests, it is the combination of community with a development that aims to enhance people’s living standards in a community.Just after the independence, India chooses to follow the path of planning for social and economic development. To inculcate the plan “The 5-year planning commission” was set up on March, 1950 under the chairmanship of Pandit Jawaharlal Nehru, The first Prime Minister of India. Government of India realized the importance of physical fitness and sports activities for the people of India, and took various important steps to improve its status. An important step in that direction was the establishment of a committee which was named “Tara Chand Committee” This committee came into existence in the year 1948. From then on several sports board, sports authority, sports commission has been set up for physical fitness and the holistic development of the citizen of India. Physical fitness can be defined as the ability to perform daily tasks efficiently and without undue fatigue, retain ample reserve to enjoy vigorous leisure time activities, importance, effort and money. But the main outcomes from all the sports planning commission were for the competitive sports. The youth were encouraged to secure medals, from National or International competitive sports. Monetary support, sports facilities were provided only for the Champions, Runner up and maximum to the third position holder. Though the number of youth is very few (34%) of the total population. And among them only 8% comes under the arena of games and sports. Nearly in the end of 21st century a word “wellness” has been emerged with the fitness for the sedentary people. Wellness is optimal health and vitality. There are several dimensions of wellness, Physical wellness, emotional wellness, intellectual wellness, spiritual wellness, interpersonal and social wellness, environmental, or planetary wellness.It can be said that the most of the youth are behind the flame of the candle light of the Ministry of Youth Affairs and Sports of India. “Health is Wealth” but wealth is not only the property for a very few people of a country.” Sports for All” is not only some letter to make a word, but the word must be implemented. Sports are not for one’s interest but for the interest of the country. The country is not only for one but for all. The slogan “Fit India” is not only a ceremonial programme. To make India “Physically Fit”, mentally strong, spiritually higher, socially more uplifted, proper action should to be taken. Fitness is not only essential for the young people only, fitness is a very important components of all the human, and as human are a very big resource of a country (called “human resource”), human resource may not be calculated without hole population of the country. demonstrate physical activity traits and capacities that are consistent with minimal risk of developing hypokinetic diseases. Fitness can promote relaxation, reduce stress and improve mental health. Mental health is reflected in the optimal functioning of the mind, and emotions. Fitness is not only a state for younger but is the reality for all ages. It is the product of exercise, and exercise is related to health. Exercise will provide benefits if it is performed as an integral part of one’s life style. The result of exercise are short lived and therefore the development and maintenance of physical fitness depends upon constant participation that adheres to the principles of intensity, frequency, duration, progression and over-load, Sporadic exercise does not promote physical fitness nor does it contribute the health.Since Independence of India, we have seen that from the first five year plan up to twelfth five year plan, planning commission provided a huge amount of importance, effort and money. But the main outcomes from all the sports planning commission were for the competitive sports. The youth were encouraged to secure medals, from National or International competitive sports. Monetary support, sports facilities were provided only for the Champions, Runner up and maximum to the third position holder. Though the number of youth is very few (34%) of the total population. And among them only 8% comes under the arena of games and sports. Nearly in the end of 21st century a word “wellness” has been emerged with the fitness for the sedentary people.

Aim of the Study: This research aims to investigate the relationship between participation in competitive sports and oral health among children. Focusing on hockey and football players, the study examines how environmental factors, especially ambient temperature, and physical activities impact oral hygiene, dental decay, periodontal inflammation, and salivary oxidative stress. Materials and Methods: The study involved 173 children aged 6 to 17, including 58 hockey players, 55 football players, and 60 non-athletic controls. Oral health was assessed using Oral Hygiene Index-Simplified (OHI-S), Decayed/Missing/Filled Teeth (DMF-T), and Papillary-Marginal-Attached Gingival (PMA) Index. Salivary oxidative stress was evaluated through biomarkers such as glutathione peroxidase (GPX), superoxide dismutase (SOD), and total antioxidant capacity (TAC). Data analysis was performed using MedCalc software, adhering to STROBE guidelines and employing chi-squared tests and t-tests for statistical significance. Results: The findings indicate that children engaged in competitive sports show significantly better oral health than the control group. This is evidenced by lower scores in OHI-S, PMA, and DMF-T indices among athletes, suggesting improved oral hygiene and reduced incidence of periodontal disease and dental caries. Additionally, higher levels of GPX and TAC were observed in athletes, indicating a positive impact of sports on managing salivary oxidative stress. However, lower SOD activity was also noted in these children. The study also reveals significant differences in oral health based on age, gender, and type of sport, with older children and males generally exhibiting better outcomes. Conclusions: The study concludes that regular participation in competitive sports like hockey and football positively influences oral health in children. Improved oral hygiene, lower prevalence of dental diseases, and enhanced management of oxidative stress are key benefits observed in young athletes. Despite its limitations such as small sample size and a specific focus on two sports, this research underscores the positive correlation between sports activity and oral health, paving the way for further comprehensive studies in this area.

Discuss the impact mechanism of different exercise load on the expression of hippocampal neurons nNOS in rats. Divided 40 Wistar male rats randomly into control group of no exercise intervention and experimental groups in which the rats were applied small, medium and large intensity exercise load respectively by swimming 15, 30 and 60 minutes everyday. After experiment for 8 weeks, the expression level of hippocampal neural n-NOS were inspected by S-P Immunohistochemical Assay (IHCA). Comparing with the control group, the positive expressions of hippocampal neurons nNOS in rats of both medium and large load group are very prominent (p < 0.01); comparing with the small load group, both medium and large load group show significant difference (p < 0.05 and p < 0.01); the comparison between the medium and large load group also shows very significant difference (p < 0.01). The expression of brain hippocampal neurons nNOS is significantly improved with the increase of exercise load.

The primary purpose of this study was to determine the fitness variables with the highest capability for predicting hockey playing potential at the elite level as determined by entry draft selection order. We also examined the differences associated with the predictive abilities of the test components among playing positions. The secondary purpose of this study was to update the physiological profile of contemporary hockey players including positional differences. Fitness test results conducted by our laboratory at the National Hockey League Entry Draft combine were compared with draft selection order on a total of 853 players. Regression models revealed peak anaerobic power output to be important for higher draft round selection in all positions; however, the degree of importance of this measurement varied with playing position. The body index, which is a composite score of height, lean mass, and muscular development, was similarly important in all models, with differing influence by position. Removal of the goalies' data increased predictive capacity, suggesting that talent identification using physical fitness testing of this sort may be more appropriate for skating players. Standing long jump was identified as a significant predictor variable for forwards and defense and could be a useful surrogate for assessing overall hockey potential. Significant differences exist between the physiological profiles of current players based on playing position. There are also positional differences in the relative importance of anthropometric and fitness measures of off-ice hockey tests in relation to draft order. Physical fitness measures and anthropometric data are valuable in helping predict hockey playing potential. Emphasis on anthropometry should be used when comparing elite-level forwards, whereas peak anaerobic power and fatigue rate are more useful for differentiating between defense.

To determine if generic off-ice physical fitness tests can provide useful predictions of ice hockey players' match performance. Approximately 40 to 60 defenders and 70 to 100 forwards from the Norwegian male upper ice hockey league were tested for strength (1-repetition maximum in squat and bench press), power (40-m sprint and countermovement jump), and endurance (hanging sit-ups, chins, and 3000-m run) annually at the end of every preseason period between 2008 and 2017. Measures of match performance were each player's season mean counts per match of assists, points, goals, penalty minutes, and plus-minus score. Overall, match performance measures displayed trivial to small correlations with the fitness tests. More specifically, points per game had at most small correlations with measures of strength (range, approximately -0.2 to 0.3), speed (approximately -0.2 to 0.3), and endurance (approximately -0.1 to 0.3). After adjustments for age that showed moderate to large correlations with player match performance, multiple-regression analyses of each test measure still provided some predictability among players of the same age. However, players selected for the national team had substantially better mean scores for most tests and match performance measures than those not selected, with a moderate to large difference for age, 1-repetition maximum squat, and 1-repetition maximum bench press. Fitness tests had only marginal utility for predicting match performance in Norwegian hockey players, but those selected into the national team had better general fitness.

Impact of unit load size on in-plant materials supply efficiency

Introduction: The shape, physiological function, and physical fitness (exercise ability) of the human body are the main parts of physical fitness. Different sports kinesiology methods have different effects on the human physique. System science-related theories can be applied to the research of the human health system under medical theory. Objective: We researched the human body's physique and formulate relevant sports kinesiology programs for the human body. We could analyze the influence of human body shape and physiological condition on human body constitution. Methods: We conducted research on the human body's physical health and nutrition through methods such as physical tests, anthropometric measurements, diet surveys, and laboratory examinations of the human body. Analyzing the correlation between sports and human body conditioning medicine had a favorable outcome in the study. Results: The sports kinesiology program has apparent effects on improving and enhancing human body shape, physiological functions, and physical fitness. Conclusion: The sports kinesiology program has a significant effect on improving the physical fitness of the human body.

Falls resulting from age-related declines in physical function significantly affect the quality of life in older adults and increase healthcare costs. While functional training (FT) helps mitigate these declines, its impact on metabolic load is limited. Blood flow restriction (BFR) training, which enhances metabolic stress through low-intensity exercise, has emerged as a promising alternative. This study aimed to investigate whether combining BFR with FT (BFR-FT) leads to greater improvements in physical fitness in older men compared to FT alone. Thirty healthy older men (71.07±5.51 years) were randomly assigned to FT, BFR-FT, or control (CON) groups. The study included pre-test, intervention, and post-test phases. Pre-test data were collected one week before the intervention. Physical fitness was assessed using the Timed Up-and-Go, 2-Minute Step, Functional Reach, Chair Sit-and-Reach, 30-Second Arm Curl, and 30-Second Chair Stand tests. Fall self-efficacy was measured using the Modified Falls Efficacy Scale (MFES). The FT program included 11 functional exercise stations. Participants performed 10 repetitions per station and completed three circuits per session. The intervention lasted four weeks, with three sessions per week. For the BFR-FT group, the same FT exercises were performed with blood flow restriction cuffs worn on the proximal limbs. Arterial occlusion pressure was measured during the pre-test using an ultrasound Doppler probe, and cuffs were maintained at 50% arterial occlusion pressure throughout training. Post-tests were conducted using the same procedures as pre-tests for consistency. Data were analyzed using two-way ANOVA, with post-hoc LSD tests for group comparisons. Significant main effects of group and time were observed in the Timed Up-and-Go (p &lt; 0.001), 2-Minute Step Test (p &lt; 0.001), Functional Reach Test (p=0.013), and 30-Second Chair Stand (p &lt; 0.001), with the BFR-FT group outperforming both the FT and CON groups. Significant differences were also found in the 30-Second Arm Curl (p &lt; 0.001) and MFES (p &lt; 0.001), favoring BFR-FT over FT alone. No significant interactions were found for the Chair Sit-and-Reach Test. This study shows that combining BFR with FT significantly improves mobility, balance, and strength in older adults, compared to FT alone. BFR enhances the metabolic load of low-intensity exercise, enabling significant muscle activation without excessive strain, making it ideal for older adults. FT improves functional mobility and coordination, and when combined with BFR, maximizes training benefits and reduces fall risk. The results provide preliminary support for the BFR-FT intervention, offering valuable insights into improving physical function and overall well-being in older adults.

Introduction: Traditionally, patients with heritable thoracic aortic disease (HTAD) have been restricted from competitive sports due to concerns over acute aortic dissection. Patients with HTAD also exhibit lower quality of life (QOL) and physical fitness than general populations. Murine data suggests exercise improves aortic health and does not contribute to aortic enlargement. Hypothesis: Exercise and competitive sports participation will be associated with improved QOL in HTAD patients. Aims: Investigate the effect of lifetime exercise ‘dose’ and competitive sports participation on QOL in patients aged 15-35 with syndromic HTAD [Marfan syndrome (MS), Loeys-Dietz syndrome (LDS), vascular Ehlers-Danlos syndrome (vEDS)] and non-syndromic HTAD. Methods: This cross-sectional study employed a questionnaire to assess lifetime exercise exposure and utilized the PedsQL QOL Inventory. We developed an Exercise Score (ES) to quantify lifetime exercise exposure based on questionnaire results (3 points for competitive sports season, 1 point for recreational sport season. Questionnaires were completed via telephone interview with complimentary medical chart review. Results: Of the forty patients enrolled, the mean age was 26 years. The diagnosis was MS in 82.5%. Despite 87.5% of patients being restricted by their cardiologist, 65% reported competitive sports participation and 92.5% reported some lifetime recreational exercise. The median ES for our population was 19. Participants with an ES greater than the median had a significantly better total QOL score compared to participants with an ES below the median (78 vs 65, p=0.03). There was no difference in aortic size or need for surgical intervention between those above and below the median ES. This also held true for those who did and did not participate in competitive sports. There was a strong positive correlation between the amount of current exercise (days-per-week) and total QOL score (corr=0.55, p&lt;0.001). Conclusions: Increased lifetime exercise exposure and current physical activity levels were associated with improved QOL in young adults with HTAD. There did not appear to be a detrimental effect of exercise on aortic size or need for surgical intervention.

The present study is to identify factors contributing to underreporting of concussion in adolescent athletes. Qualitative interviews. Participants were interviewed in an office environment. Interviews were conducted with 31 minor hockey players, 10 parents, 6 coaches, 4 trainers, 2 managers, and one game official. Players were 13 to 15 year old. With selective sampling, an inductive approach of analyzing the interviews was undertaken and themes were identified and analyzed. Underreporting is a complex phenomenon. A number of risk factors related to hockey culture, players, reference others, and rules of play were assessed. Reasons not reporting concussion is accepted in minor hockey. Aspects of hockey culture such as an overemphasis on winning games and upheld misperceptions about the risks associated with concussion were identified as relevant to the underreporting of concussions. Various factors relevant to the underreporting of concussions include player's motivation to win, group membership dynamics such as a player's role as the team's "enforcer," coaches' own motivation to win to further their own opportunities in the sport, and parents' personal financial interest or alternative agenda in terms of time commitments and their child's future career prospects. Our findings indicate that underreporting of concussion among those players interviewed appears to be prevalent and associated with misconceptions about injury risk, and a culture that both reinforces and encourages underreporting with tacit or overt complicity of parents and coaches. Our findings support the need to alter the culture of violence and tough play in hockey by education, rule changes, economic measures, and changes in governance of the sport. Interviewing more stakeholders and policy makers would shed light on such potential interventions.

Sharma A, Tripathi V, Koley S. Correlations of anthropometric characteristics with physical fitness tests in Indian professional hockey players. J. Hum. Sport Exerc. Vol. 7, No. 3, pp. 698-705, 2012. The purpose of this study was to investigate the correlations of anthropometric characteristics with isotonic strength (handgrip strength), lower limb power, aerobic strength, and skill tests in purposely selected 60 Indian professional male hockey players of different levels players (35 national and 25 state level) aged 18-23 years collected from Ranjit Singh Hockey Academy, Amritsar, Punjab, India. To serve this purpose, three anthropometric characteristics (height, weight and percent body fat), right and left handgrip strength, vertical jump, multi stage fitness test, slalom sprint and dribble tests were performed on each subject. Results indicated statistically significant (p<0.05) differences only in lower limb power between Indian national and state level male hockey players. In Indian professional male hockey players, height has significantly positive correlations with weight, right and left handgrip strength, lower limb power and negative correlations with % body fat and dribble test, and body weight has significantly positive correlations with % body fat, right and left handgrip strength, lower limb power and negative correlations with slalom sprint. Significantly positive correlations were noted among the fitness component variables too.

Efficient Dynamic Embeddings of Binary Trees into Hypercubes

Serial response to auditory stimuli administered during dynamic physical exercise of the steady-state and non-steady-state exhaustive nature was investigated in 61 athletes. Similarly to previous studies with serial visual stimuli, auditory reaction time was found to depend on the exercise load and grew in parallel to it. The latency increase followed the character of the imposed exercise, too. In the slope of the latency increase individual and group differences were noted that, at least in part, could be explained by the existing differences in physical fitness plus motivation. Overall mean of linear correlation was 0.61 between the latency of auditory reaction and steady-state work output and 0.47 for the non-steady-state all-out efforts in our material. Reaction time tended to increase also when the effort though being constant was subjectively exhaustive during the studied duration (r = 0.46). As shown by the results, the decisive factor in this was not so much the absolute severity of work, but rather subjective fitness level. Despite that the data throughout the study were modeled by fitting a linear model, the conclusions are not contradictory to Duffy's inverted U-shape activation theory if understood in Gutin's interpretation.
