The purpose is to select and develop an exercise program adapted to the rate of contribution of biomechanical variables affecting the result in javelin throwing. Methods and organization of the research 1. Consideration of biomechanical variables in the development of javelin training process for the Iraqi national team has made a great contribution to sport performance. 2. We used data of a biomechanical analysis and a specialized physical fitness test to identify the levels of technical performance and physical fitness of the research participants. 3. The outcomes of the initial level of technical performance and specialized physical fitness enabled the development of models of technical performance and physical fitness with individual characteristics for participants in the experimental group. 4. Mathematical treatment of the educational experiment results revealed statistically significant differences between the experimental and control groups. Results Exercises designed by the researcher in accordance with the contribution of the variables to the result positively affect not only performance of participants in the experimental group, but also modification of important variables in the throwing technique. Conclusion Javelin throw is a complex coordinated motor action. Its result depends on both the level of specialized physical fitness and technical excellence of an athlete. A biomechanical analysis of the technique of research participants, computerized processing of the results of technique analysis, and the creation of an experimental training program for athletes based on comparison with the criteria of outstanding throwers’ technique enabled improvement of sport performance and biomechanical variables of the javelin throw technique by the end of the experiment.

The problem in this study is that the level of students' physical fitness is still relatively low, so it is necessary to have an optimal exercise program for physical fitness. The purpose of this study was to determine the level of fitness after doing Circuit A and Circuit B. The method used was a quasi-experimental method with a Nonequivalent Control Group Design research design. Where in this design there are two groups, namely one experimental group and one control group, and 60 students were divided into two parts and sampled for the experimental group using ordinal pairing technique. The instrument used is TKJI for ages 10-12 years. The results of this study: 1) Circuit A, r arithmetic 0.908 > r table 0.3610 with = 0.05, N = 30 there is a significant effect. 2) Circuit B, r count 0.8903> r table 0.3610 with = 0.05, N= 30 there is a significant effect. 3) Different test with t count 2.08 > t table 1.671 = 0.05, N = 60 there is a difference. So circuit training A is better in improving students' physical fitness. So that in this research it is hoped that in the future it can be used as a reference for the circuit training A training program as a reference for physical fitness training at the elementary school level.

Physical fitness is the body's ability to carry out physical activities without causing excessive fatigue. For a military soldier, physical fitness plays an important role in improving and maintaining the military body, in order to support the implementation of the main tasks of military soldiers. Physical fitness can be optimized, one of which is the core stability exercise. This study aims to analyze the effect of adding core stability exercise to increase physical fitness A (endurance) in military soldiers at Brigif 15 Kujang II Cimahi. A quasi-experimental study with a pre-post two group design approach consisting of an experimental group and a control group. With purposive sampling technique, 48 people were selected which were divided into two groups, namely the experimental group (n=24) and the control group (n=24). The experimental group was given a 12-minute running exercise program and core stability exercise while the control group was only given a 12-minute running exercise and data collection in the form of a 12-minute running test. There was a difference in the mean physical fitness score A between the experimental group (Mean= 40.33; SD= 3.54) and the control group (Mean= 44.17; SD= 6.72) before the intervention, and the difference was statistically significant (p= 0.017). There was a difference in physical fitness scores before and after the intervention between the experimental group (Mean= 4.38; SD= 1.41) and the control group (Mean= 2.42; SD= 2.04) and statistically significant (p<0.001), with effect size = 1.14. Core stability exercise is effective to increase the value of physical fitness A in Brigif 15 Kujang II Cimahi soldiers.

The main purpose of this paper is the biomechanical analysis of the kinematic and dynamic indicators of sports technique used in Yurchenko handspring vault by means of the macro methods for exercises learning during the training basic specialization stage. This scientific approach led to the organization of an experimental study, using the research methods as follows: 1. Method of theoretical and methodological analysis of literature related to artistic gymnastics. 2. Method of evaluation of gymnastics exercises sports technique using the algorithmic analysis of the motion. 3. Video computerized method, using” Pinnacle Studio”,” Kinovea” and” Physics ToolKit” programs. 3. Method of movement postural orientation and evaluation of key elements of sports technique with complex coordination of movement structure. 4. Method of linear-branched programming of gymnastics exercises learning and improving. 5. Statistical method, by means of” KyPlot” program. The research was conducted from 2012 to 2014, when gymnasts’ performances were monitored in three national competitions - handspring vaults event; a number of 7 athletes aged 12 to 15 participated in these competitions, all of them members of junior national team of Romania. The results of the research highlighted and identified the kinematic and dynamic characteristics of sports technique key elements of Yurchenko vault in women’s artistic gymnastics.

An intensive physical exercise program could lead to a decrease in immune system function. Effects of long-term supplementation of bovine colostrum on the response of immune function on physical exercise test in athletes were examined. Twenty-seven elite female basketball players (age 16–19) were randomly assigned to either an experimental group or a control group. Eventually, n = 11 athletes completed intervention in the experimental group (3.2 g bovine colostrum orally twice a day for 24 weeks), while n = 9 athletes in the control group were given a placebo. Before the supplementation, after 3 and 6 months, subjects performed the physical exercise stress test. Before, just after, and 3 h after physical exercise testing, blood was drawn and immune system indicators were examined. Plasma interleukin (IL)-1alpha, IL-2, IL-10, IL-13, tumor necrosis factor (TNF) alpha, creatine kinase (CK MM), immunoglobulin G (IgG), insulin-like growth factor 1 (IGF1), and WBC, lymphocyte (LYM), monocyte (MON), and granulocyte (GRA) were measured. A statistically significant change in IL-10 in response to the exercise program during the supplementation period in both groups was observed (p = 0.01). However, the results of the rest of the comparisons were statistically insignificant (p > 0.05). Contrary to our initial hypothesis, there were no significant effects of bovine supplementation on the dynamics of immune system function indicators.
