The influence of different physical education programs on police students' physical abilities

Purpose – The purpose of this paper is to determine the influence of different Specialized Physical Education (SPE) teaching programs on the level of students’ physical abilities. Design/methodology/approach – In the Academy of Criminalistic and Police Studies (ACPS), one of the teaching program goals is an improvement of students physical abilities level. Since the establishment of ACPS, three SPE programs have been implemented differing in number of class hours. Five different tests were used: “Isometric dead lift,” “Hand grip,” the Long jump (LJ), the Sit-up test and the Cooper test. Findings – Multivariate analysis of variance results indicated a statistically significant difference between the programs in tests LJ, Sit-up and Cooper. The Bonferroni test showed differences between all three programs. The discriminant analysis showed that both discriminant factors are statistically significant. The greatest factor in the first function was the test LJ, while the greatest factor in the second discrimin...

Trend of changes of student results at the Academy of criminalistic and police studies entrance exam

The aim of the research was to determine the trends of changes on the Academy of Criminalistic and Police Studies (ACPS) entrance exam. Furthermore, the paper is to find whether there are any differences between the sexes in the terms of the results of the entrance exam. 1.576 examinees participated in the research (621 female and 955 male), all of which entered the ACPS as the students of basic and vocational studies. The paper analyses their scores in all components of the exam: High School Achievements (HSA), General Knowledge Test (GKT), Serbian Language and Literature Test (SLLT), the Level of Basic Motoric Abilities development (BMA) and the overall number of points achieved on the test. The results were firstly analysed by applying the basic descriptive statistics procedure, which determined the equation of trend of changes and R-squared values. The existence of the general variability differences between groups was determined by using MANOVA, while for the determination of partial differences between pairs of variables the Bonferroni test was used. The 1 This paper is the result of the research on project: “Management of police organization in preventing and mitigating threats to security in the Republic of Serbia“, which is financed and carried out by the Academy of Criminalistic and Police Studies, Belgrade – the cycle of scientific projects 2015–2019. Radivoje Janković, Nenad Koropanovski [94] NBP • Žurnal za kriminalistiku i pravo positive changes trend for both sexes in HSA and the negative one in SLLT were demonstrated. In females, a positive trend in BMA and a negative GKT trend were observed. However, an opposite effect was detected in males. Nevertheless, despite the different trends in individual tests, the overall number of points achieved on the entrance exam demonstrated a positive trend of changes in both populations. MANOVA results showed that the females had statistically better results in HSA, SLLT and BMA variables, but worse results in GKT. The overall result on the entrance examination taken into account, the females had statistically better scores by 3.31%.

Neuromuscular contractile characteristics among Police academy students and high level karate athletes

Methods: Twenty-three rugby players were randomly assigned to either a control (PAR) or an experimental (CWT) group. Following a 15 min long fitness session, the CWT-group alternated between warm water (40±2 °C; for 3 min), and cold water (8±1 °C; for 1 min), within the 20-min recovery period while the PAR-group remained seated. Haematological and physical indicators were evaluated at baseline, 0 h post-fitness and at 0, 24 and 48 hours post-recovery.T social facilitation theory states that performances can improve with the presence of a crowd. The information on this theory suggests that with a crowd/spectators present, an athlete will perform better. This survey aims to define the connection between an athlete’s experience and their psychological disposition towards spectators. Training age is defined as the number of years an athlete has spent within a specific sport. Research suggests that athletes of a higher training age will outperform those of a lower training age. Within a sport, such as running, the concept of training age could be questioned due to performance situations where athletes with a higher training age have been outperformed by athletes with a lower training age. Depending on the level of psychological arousal an athlete experiences during competition, performance could increase or decrease regardless of training age.Background & Objectives: To compare the mean percentage improvement in coordination, strength and disability in overhead throw athletes with partial thickness tear of the rotator cuff following plyometric training in different phases of rehabilitation. Methods: a total of 30 male overhead throwers suffering from partial thickness tear of the rotator cuff injury, on the basis of inclusion criteria were taken in the study. A full description of the study, including the selection process was explained to each patient. Documented consent was obtained from each patient. Group 1 consisted of athletes with history of rotator cuff injury one and half year back and group 2 included athletes with rotator cuff injury three months back. Coordination , strength and disability were assessed pre and post plyometric training for a period of three weeks and the mean percentage of improvement were compared in both the group following plyometric training. Results: intragroup analysis showed a significant improvement in coordination, strength with the level of significance (p<0.05). Discussion & Conclusion: group 1 showed an improvement in the mean percentage in coordination, the strength of supraspinatus muscle, and bench press when compared to the group 2. While the group 2 showed an improvement in mean percentage in the strength of the subscapularis, teres minor muscle and infraspinatus muscle when compared with the group1.Methods: Thirty-six elderly people with MCI were recruited and randomly assigned to a resistance exercise (RE) group (n-12), aerobic exercise (AE) group (n=12), and non-exercise-intervention (control) group (n=12). Cognitive performance was measured when individuals performed a task-switching paradigm at baseline and after either an acute bout of 30 minutes of moderate-intensity RE, AE, or a control period.Purpose: Despite the high incidence of hamstring strain injuries in several popular sports, definitive research on their causation and prevention is limited. Studies show fatigue and also hamstring eccentric weakness as causes for hamstring injuries. It begs the question “which way may be the best to train hamstrings to prevent injury. Methods: Eccentric hamstring peak torque and angle of peak torque toque were measured using the Kin Com dynamometer at 60˚s-1/s (type, 125 AP, Chattanooga, TN, USA) before and after a modified L.I.S.T fatigue protocol. Participants were divided into two groups and underwent four weeks of eccentric hamstring training, then retested. The strength group used Nordic Hamstring Curls and the endurance group used Assisted Nordic Hamstring Curls. Results: The results showed a significant difference in peak torque in both groups (strength- .00, Endurance- .01). Both groups did not show a significant difference in angle of peak torque, however the results showed an increase to longer muscle lengths of 18.28% and 26.95% for endurance and strength groups respectively Conclusions: The strength training intervention shows the greatest improvement on both peak torque and angle of peak torque.Methods: It is a retrospective cohort study, conducted in a sports club at Al Ahsa, recruiting all its members receiving professional training in soccer and basketball. We asked 108 athletes to fill our questionnaire and with the help of this we identify individuals, sustaining sports related injuries and assess the overused injuries in knee, lower back and shoulder by using Oslo Sports Trauma Research Centre (OSTRC) Overuse Injury Questionnaire. We then segregated these individuals according to the age when they sustained such injury, either pediatric group (less than 18 years) or adult group (more than 18 years). Besides this we also segregated the individuals according to the type of sports they are training for as well as the type of sports injury, they are sustaining. The results were analyzed by SPSS (version 16.1) Result: Soccer is the most chosen sports by majority of athletes. Basketball is another choice among athletes. Soccer also has highest incidence of sports related injuries, followed by basketball. Among regions of involvement, it is the knee which is mostly involved (22.2±0.7%), followed by lower back (8.3±0.4%) ,and significant amount of athletes (30.0±0.6%) suffer injuries in sites other than knee , lower back and shoulder such as ankle and foot . Conclusion: It is better to prevent the sports related injuries than to treat them. With prevalence study like this, done on a much larger scale, we may preserve our athletes and thus in turn can enhance the overall sports performance of country by taking preventive measures beforehand.M rehabilitation programs will go through an acute stage immediately after injury i.e., a middle stage where the aim is to regain normal movement and strength and finally a functional or sports specific phase where exercises are more relevant to the activity. Hence, the sports rehabilitation programs at the work-out/weight lifting room will make a plus in your daily practice, in addition to all other techniques and equipment you may use, therefore, speeding the athlete’s recovery.A periodization of training is of paramount importance for optimal performance in sport. Many tools have been developed aiming to help the technical staff to better monitor training load and fatigue in professional football. In this context, the aim of the present talk is to present 2 validated and easy-to-use tools. (1) The session-RPE method for quantifying training has become popular tool for monitoring training periodization in various sports, and many football teams have adopted this approach. This method allows coaches to monitor individual player’s perception of training loads (TLs) and follow its periodization. Additional psychometric tools can also be used to assess how players are responding to training. (2) The Hooper Index allows assessing the status of the player with respect to his/her perceived sleeping quality, and the quantity of stress, muscle soreness and general fatigue. The effectiveness of the training programs depends on the successful manipulation of the total training load. Appropriate and balanced manipulation of training load and subsequent recovery allows for the optimal balance between the effects of training induced catabolism and the re-establishment of energy stores and protein catabolism in the regeneration process. It is suggested that there is a supercompensation in performance as the athlete adapts to the stress imposed by the training bout. The presentation will provide the scientific validation evidence of these tools in addition to practical examples of their daily use with professional football players.Background: Adipose tissue has gained increased interest in the medical and scientific community over the last few years as a source for ortho-biologic therapies. It is readily accessible and simple to harvest. Adipose can be used to provide cushioning and filling of structural defects and has been shown to have an abundance of bioactive elements and regenerative perivascular cells. Objective: To evaluate the potential benefits of injecting a severely arthritic knee with concurrent meniscal disease with micro-fragmented non-digested adipose tissue using a novel technique by obtaining minimally manipulated and micronized fat tissue with intact stromal vascular niches harboring regenerative cellular elements. The case is nonresponsive knee pain with osteoarthritis and concurrent meniscal disease. Case description: This case is the first of a 100-subject IRB study approved by IRCM. The patient is a 59-year-old male with severe knee pain who has failed a multitude of treatments, including arthroscopic meniscal surgery. The MRI prior to surgery revealed evidence of osteoarthritis, medial meniscal tear, and chondromalacia patella. The patient was followed for 6 months, and will continue to be followed for two years. Material and Methods: Micro-fragmented fat was obtained by using a minimal manipulation technique in a closed system (Lipogems), without the addition of enzymes or any other additives. The final product consisted of micronized fat tissue yielding fat clusters with preserved vascular stroma of about 500 microns with intact stromal vascular niches and harboring regenerative cellular elements. In this treatment protocol, the micronized fat was injected with a 22-gauge needle under continuous ultrasound guidance into the joint and filling the hypoechoic defects in the medial meniscus. No other biological or pharmacological agents were used in combination with the micronized fat. Outcomes were measured immediately following the treatment, 24 hours, 1 week, 5 weeks, 3 months and 6 months after the injections. At 6 months, a repeat MRI of the joint was performed. Results: Six months after the treatment, we found improvement in all measured scores. VAS pain score on a 1-10 scale, with 10 being worse, improved from 8 to 2; the KOOS (Knee Injury and Osteoarthritis Score) outcome, with a score of 100 being perfect, improved from 45 to 96. MRIs taken at 6 months post-treatment, revealed improved signal and thickness of the cartilaginous tissue over the medial femoral condyle, with a widened joint space. Radiologist initial measure of articular cartilage reported as 0.75mm and at 6 months reported as 1.5mm. Conclusion: The injection of autologous micro-fragmented adipose tissue obtained with the new technique, Lipogems in the case of non-responsive knee pain appears to be a promising and viable treatment. Due to the arthroscopic surgery taking place following the original MRI and prior to the treatment with micronized fat, the change in the meniscus after 6 months is not comparable. Further studies are underway.
