The quality of maximum oxygen volume (VO2max) for athletes is important for an athlete's performance. VO2Max is the maximum volume of oxygen that can be used per minute. The maximum amount of oxygen consumed per unit time by a person during exercise or tests, with training progressively heavier until exhaustion, is called VO2Max. The Vo2Max Direct examination is the most accurate test in determining the level of heart and lung fitness in performing physical activities with maximum intensity. Maximum oxygen uptake (Vo2max) is defined as the maximum value at which oxygen can still be taken, distributed, and used by the body when the intensity of physical activity reaches its maximum. This service method provides material on the importance of evaluating physical conditions, especially Vo2max to athletes. This service aims to help the Indonesian National Sports Committee (KONI) Rokan Hulu Regency to find out the fitness of athletes from several sports as seen from VO2 Max. The method used in this service is that all athletes follow the service's direction about the importance of VO2 Max and perform a Multistage Fitness Test (MFT). The results of this dedication by the athletes and management of KONI understand the importance of VO2 Max and the results of the MFT test, only a few athletes in good and other categories are sufficient and low.

Background: Maximum oxygen uptake (VO2max) is an important respiratory physiological index of the aerobic endurance of the body, especially for special groups such as drug addicts, and it is an important indicator for assessing the cardiopulmonary function and formulating exercise prescriptions. Although the cardiopulmonary exercise test (CPX) is a classic method to directly measure VO2max, this method is limited by factors such as cumbersome operating procedures and expensive equipment, resulting in its relatively low applicability. Recently, many studies have begun to focus on the estimation of VO2max in different groups of people, but few studies have focused on drug addicts.Methods: Fifteen chemically synthesized drug addicts (such as amphetamines) and Fifteen plant-derived drug addicts (such as heroin) were recruited at the Chongqing Compulsory Isolation and Drug Rehabilitation Center in China. First, the VO2max of subjects was directly measured through the CPX. Second, after subjects were fully rested, they were required to complete the 30-s high-leg raise, 1,000-m walk, and 3-min step experiment. Finally, SPSS 21.0 software was used to perform the correlation and linear regression analysis to verify the estimated effectiveness.Results: (1) Regardless of chemically synthesized or natural plant-derived drug addicts, the years of drug use and walking time of 1,000 m were significantly negatively correlated with VO2max (chemically synthesized: P < 0.01 and natural plant-derived: P < 0.05), the number of 30-s high-leg raises was a significantly positive correlation with VO2max (P < 0.05 and P < 0.01), and the 3-min step index was significantly positively correlated with VO2max (P < 0.01 and P < 0.01). (2) Regression analysis shows that the 30-s high-leg lift, 1,000-m walking, and 3-min step experiment could effectively estimate the VO2max of chemically synthesized and natural plant-derived drug addicts. (3) Multiple linear regression constructed by the years of drug use combined with the step index has the highest estimated accuracy for the VO2max of chemically synthesized drug addicts (96.48%), while the unary regression equation established by a single step index has the highest prediction accuracy for the VO2max of natural plant-derived addicts (94.30%).Conclusion: The indirect measurement method could effectively estimate the VO2max of drug addicts, but different measurement methods have certain differences in the estimation accuracy of VO2max of different drug addicts. In the future, the physical characteristics of drug users can be fully considered, combined with more cutting-edge science and technology, to make the estimation accuracy of VO2max closer to the real level.

Background and Objectives: Maximum Oxygen uptake (VO2 max) is a good predictor of cardiopulmonary and muscle fitness. Maximum oxygen uptake is defined as the highest rate at which oxygen can be taken up and utilize by body during severe exercise. The present study aims to find out the level of VO2 max using Mc Ardle equation and to compare obtained values from Chatterjee’s equation in Nepalese population. Methodology: Maximum oxygen uptake was determined by using the Queen’s college step-stool of 16.25 inches and popular Mc Ardle equation. Stepping was done for a total duration of 3 minutes at the rate of 24 cycles per minute for males and 22 cycles per minute for females. After completion of the exercise, subjects remained standing while the carotid pulse rate was taken as heart rate. Maximum oxygen uptake was calculated using obtained heart rate. Results: Queen’s college step test (QCT) was used as a submaximal exercise and the estimated VO2 max in boys and girls was 48.8± 7.3 ml/kg/min and 37.4± 2.7 ml/kg/min respectively with Mc Ardle equation and the value was higher when compared with Chatterjee’s equations. The value of VO2 max was observed and found to be less in smokers and sedentary individuals. Conclusion: As the values of VO2 max obtained from different equations are different, this research strongly argues the need of developing a prediction equation specifically for the Nepalese population.DOI: http://dx.doi.org/10.3126/jmcjms.v1i1.7879 Janaki Medical College Journal of Medical Sciences (2013) Vol. 1 (1):3-8

The cardiorespiratory responses to weight reduction due to physical exercise were examined in fourteen women with obesity, aged 36 to 67 years (Body Mass Index, 32.4 ± 1.4 kg/m2). The patients were instructed to exercise at approximately 60% of maximum oxygen uptake for 2 h every day for approximately 3 months. To evaluate physical strength, a graded cycling exercise test was performed both before and after the exercise period, monitoring gas exchange, ventilation, and heart rate. After the exercise period the body mass index and percentage fat both decreased by 11% and 18%, respectively ( P < 0.001), although lean body mass did not change; maximum oxygen uptake and maximum heart rate did not change significantly, but peak ventilation equivalent, maximum metabolic equivalent and maximum load increased by 12%, 14% and 11%, respectively ( P < 0.05, P < 0.001 and P < 0.001, respectively). Maximum oxygen uptake per unit body weight increased by 5% ( P < 0.001). These results suggest that weight reduction as a result of exercise improves cardiorespiratory function in middle-aged women with obesity.

Abstract Analog rice is a food product resembling rice made from starch sources other than rice, such as starch from tubers (taro), corn and sago. The advantage of analog rice is that it has a lower glycemic index than rice. This analog rice product can help efforts to diversify the food consumption patterns of people in Indonesia in order to improve the nutritional quality of the food consumed and at the same time considering that analog rice is currently rich in carbohydrates and poor in other nutrients such as protein, fat and fiber, the product needs to be fortified with functional components of food. Functional components of food are foods that contain bioactive components that provide multifunctional physiological effects for the body, including strengthening the body’s immune system, regulating the rhythm of physical conditions, slowing aging, and improving people’s nutritional status and reducing dependence on imported rice. For this reason, alternative food is needed, namely analog rice with high nutritional content. This study aims to analyze the characteristics and added value of processing sago analog rice fortified with high nutritional fish oil supplements as a superior product in the Riau region, because Riau is one of the highest sago producing regions nationally. The research method used is an experimental method, which is to experiment with making sago analog rice fortified with nutrient-rich fish oil supplements from previous research. The treatment given was in the form of analog rice formulation with two levels, namely: sago analog rice fortified with 3% fish oil (M3S), and sago analog rice fortified with 5% fish oil (M5S). Data obtained were homogenized, then tabulated and analyzed quantitatively descriptively. The results showed that based on organoleptic preference test, and proximate composition, sago analog rice (M5S) was the best analog rice, namely sago analog rice fortified with 5% fish oil and met SNI quality standards. Furthermore, the added value produced to produce sago analog rice is IDR 3,000/kg and analog rice mixed with sago and taro is IDR 11,000/kg.

Background: Several factors contributed to the evolution of handball, and one of the most important changes for faster, more dynamic and aggressive game is the change of rules which increase physical demands of players and especially referees. The aim of this study is to determine whether functional abilities have an influence on the quality of refereeing. Material and methods: 31 subjects were involved in the research, all of them top-level referees with an average age of 34.66±6.44, height 184.02±5.87 cm and body mass 91.14±10.61 kg. Testing was divided into two parts: the first part was spiroergometric progressive test on a treadmill to diagnose functional abilities, and the second part was the official handball matches. Results: Results show an average relative maximum oxygen uptake of 45.35±6.12 ml/min/kg. No statistically significant correlation was found between better functional abilities of handball referees and a better quality of refereeing. Conclusions: Referees have a lower anaerobic capacity, which could lead to errors in their judgment during the highest physiological loads in a match. Referees are a homogeneous group due to elimination criteria on tests at official seminars. If there were no elimination criteria, there would be greater variability among referees, and it would be possible to confirm the hypothesis that better functional abilities would lead to a better quality of refereeing.

The main focus of this research is on the self-concept and pedagogical competence of the teacher and its influence on the quality of the learning process both partially and double. The research method used is a survey method in which the authors go directly to the empirical level by distributing questionnaires to 47 teachers. The processing and analysis techniques used are linear and multiple regression. The results of the study show that: (1) There is a positive and significant influence of the teacher's self-concept on the quality of the learning process (2) There is a positive and significant influence on the teacher's pedagogical competence on the quality of the learning process. (3) There is a positive and significant effect of self-concept and pedagogical competence of teachers together on the quality of the learning process. Therefore, the authors suggest: (1) So that the teacher improves health and appearance because the results of the study show that the weakness of the teacher's self-concept is in the appearance and significance of the body. So that the teacher needs to be given enlightenment related to how to maintain health and fitness through the implementation of joint gymnastics or conducting group discussions related to the dirt to maintain a prime body. (2) To face future competition and improve the quality of education it is deemed necessary to further increase the pedagogical competence of teachers, especially those related to planning and evaluation of learning.
