Background:Acetaminophen (also known as Tylenol or Paracetamol) is a very popular drug, that requires no prescription and is usually used as analgesic and antipyretic. A considerable number of previous studies show that acetaminophen has no effects that could alter exercise capacity or performance. Onthe other hand, there are studies sustaining that exercise performance can be improved with acetaminophen through a reduction in perceived pain, and also a reduction of the body heat produced by the muscle contraction.Purpose:The aim of our study was to check if acetaminophen influences reaction speed and power of the lower limbs muscles. Participants and method:For this study we recruited twenty-nine males, aged between 19 and 28 years old. We had two testing sessions for each participant, in the same day (the baseline evaluation, and the second evaluation at half an hour after acetaminophen ingestion).The evaluationsequence was: Body composition evaluation, acoustic-visual reaction test for one leg (left and right), Squad jump on one leg (5 jumps on each foot) and Stiffness test (7 jumps

Introduction:The field of sports nowadays experiences a continuous development, both from the sports performance and social perspective, transitioning from a free time activity to a complex industry. On this growth trend where more and more people practice sports a large sports services market has developed, which brought a new applicability for marketing in this area of consumption. The efficiency of a new marketing policy with regard to a sports entity depends on the importance given to consumer’s needs. By studying the consumer’s behavior one understands identifying the ways the consumer comes to a decision when deciding how to spend available resources (time, money, effort) in the acquisition and consumption process. Aim: Sports clubs, especially the private ones, are in a continuous competition on the sports services market, we decided to identify the demand and needs of parents in Timisoara when it comes to choosing a sports activity for their children. Methods:We obtained the information necessary for carrying out this market study based on a questionnaire. The research took place in Timisoara throughout the year 2016, and a number of 217 parents having children that were enrolled in seven different private sports clubs were included in the study, our target being sports games. Results:The results help in highlighting the needs and demand of sports consumers, offering information about the amount of money parents are willing to pay, the number of weekly training sessions, the day and location for the activities, the best advertising etc. With these data we hope that sports managers can implement new marketing strategies, having a more detailed vision on the target group.

Childhood and adolescent obesity becomes a worldwide health problem, as for the past years the prevalence of obesity amongst youngsters has reached very high levels. The increased levels of obesity at younger age rises concern at a global basis, therefore the prevalence of childhood obesity sets enormous pressure on healthcare system. Obesity is a complex trait influenced not only by genetic factors, but also by other such as: physical inactivity and unhealthy diet or overeating as well as weight status misperception. Some of the measures needed to overcome these factors is that the intervention programs used to prevent or combat obesity, must include assessment and correction of these factors, as well as monitoring their evolution over time. Questionnaires are efficient instruments that can be used for the evaluation of such parameters. This study aims to revise the scientific literature, from the last five years, to identify and centralize the most reliable and valid questionnaires created and used for the assessment of physical activity in children and adolescents.

Introduction. Obesity is a disorder characterized by an amount of body fat over the normal limits. This could be reduced when there are no metabolic disorders with good alimentation and increasing the level of physical activity. In prevention of childhood obesity beside the institution on the field that has the obligation to promote a healthy lifestyle, parents have the main role. They are responsible for the food that their children get and also for their teaching for a healthy lifestyle. However, many times, the parents’ attitude beside the obesity is inappropriate for various reasons. One of them is the fact that parents don’t perceive correctly their children body weight. The aim of this study is to assess the way a group of parents who have children enrolled to sports activity perceive their children body weight. We also wanted to check the way in which these perceptions are associated with possible attempts to lose weight. Participants and methods: In this study we evaluated 62 girls (average age: 10.29±1.32 years), these being enrolled to a private volleyball club from Timisoara. Testing protocol consisted in height measurement, evaluation of body composition and completing of a questionnaire by parents. Results. In the current research, there exist a few significant differences between the body mass index that was considered the base on which the children were put into different weight categories and the parent’s perception on the body weight of their own children; 38.7 % of the total of the children that were measured were overweight or obese and only 8.04 % were involved in a program that helps weight loss. Conclusion. The vast majority of questioned parents underestimated the real body weight of their children, choosing an inferior weight category, inferior to the real one. These perception errors of the parents affect the level of concern regarding the body weight of the children and, thus, the optimal attitude concerning it.
