Overweight between perception and reality


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.

Acetaminophen effect on reaction speed and lower limbs power


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. On the 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 evaluation sequence 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 on each foot). Results: Acetaminophen has no significant influence on visual and acoustic reaction time of left or right leg. The Squat Jump test revealeda significant increase of explosive power on left leg (from 10.19±1.66 to 10.61±1.66 W/Kg, p=0.03) and right leg (10.16±1.59 W/Kg to 10.62±1.84 W/Kg, p=0.02). Another significant result of our study is the increase of reactive power (obtained during the Stiffness test) after the acetaminophen ingestion (from 16.35±4.86 to 17.53±3.79 W/Kg on left leg and from 15.92±4.2 to 17.04±4.26 W/Kg on right leg). Conclusions: Acetaminophen ingestion does not influence visual or acoustic reaction time but can improve the exercise performance through an increase in both explosive and reactive power of lower limbs.
