Introduction
Home confinement during the COVID-19 pandemic reduced the physical activity level and exacerbated other unhealthy behaviours such as vices and eating disorders. This study analyses the risk factors predisposing to weight gain in young adults during COVID-19 home confinement.
Material and method
Four hundred thirty-three students, aged between 19 and 25, participated in an online survey to understand the factors associated with weight gain. The following lifestyle dimensions were investigated in a regression model: physical activity, personal experiences, occupation, risk of vices.
Results
We have found significant associations between weight gain (as a dependent variable), and frequency of physical activity (p = 0.009), occupational performance (p = 0.002), and alcohol consumption (p = 0.002). Male respondents are more likely to have gained weight during isolation. For an increase of one unit in the frequency of playing sports, we expect an odd of 0.25 (p = 0.048) for the respondents’ weight loss. Moreover, if the occupational performance increases by one unit, a weight decrease by a rate of 0.52 (p =0.02) is expected.
Conclusion
In conclusion, young adults less engaged in physical activity, who assessed their occupational performance as lower, and who consumed alcohol more often during home confinement are the most likely to have gained weight.
Background: The physical exertion in the game of rugby is intense and depends on the playing position. This study hypothesized that peculiarities of body composition are important and should be properly interpreted in order to improve fitness and particularly in order to reduce the risk of injuries. Purpose: The aim of the present paper is to highlight the importance of body composition evaluation and to underline the usefulness of the data thus obtained for both training individualization and sports injuries risk reduction. Material and Methods: Thirty seven senior male rugby players from the former Romanian national team were assessed on body composition using a segmental multi-frequency bio-impedance analyzer InBody 720 (The Body Composition Analyzer -South Korea). We compared the results from both the preseason and the regular season 2012 with the international norms for elite players and we categorized the data by playing positions. Results: We have analyzed the amount of lean mass on each limb (kg), body water content (l), percentage of body fat, bone mineral and protein content (kg). We observed that the number of injuries is directly correlated to high levels of body fat percentage, low lean mass, and edema scores. Conclusions: The risk of injury can be identified among elite rugby players not only by using fitness tests, but also by using a simple and objective test of body composition. These results show how important it is to monitor the level of body fat, lean muscle mass and muscular development in order to modify nutrition and food habits, individualize trainings and thus reduce the number of injuries.
The purpose of this research was to analyze how we can improve the space–temporal orientation ability with the help of physical exercises in physical education and sports lessons. In total,148 children between the ages of 8 and 11 participated in this study (M = 9.70; SD = 0.79). They were subjected to three tests, which measured general intelligence (Raven Progressive Matrices) and space–temporal orientation skills (Piaget-Head test and Bender–Santucci test). The tests were carried out both in the pre-test and in the post-test period. In the case of participants in the experimental group, a specific program was applied for a period of 12 weeks. The results showed that general intelligence level was identified as a predictor of spatial–temporal orientation (beta = 0.17, t = 2.08, p = 0.03) but only for the Piaget-Head test. Similarly, no differences between children’s age groups were identified in any of the spatial–temporal orientation test scores. However, children in the “+9” age category had higher scores on the intelligence test compared to younger children (77.31 vs. 35.70). In conclusion, the intervention program had a positive effect on spatial orientation skills.
Introduction: The current handball performance, both nationally and internationally, has obvious progress in terms of the dynamics of the game in all phases of its development in attack and defense, characterized by the speed and complexity of development throughout the game. Anthropometric parameters and physical tests have been identified as fundamental to determining the success of handball performance. Examining fitness profiles could be of great importance for the optimal preparation of training plans and the orthopedic care of high-performance handball players.
Materials and methods: Seven athletes from the handball club SCM Politehnica Timișoara, aged between 21 and 35, participated in this study. The tests conducted were aimed at evaluating the following parameters: body composition, strength of the lower and upper limbs and speed endurance.
Results: The results obtained in body composition show an average value for weight of 90.14 ± 8.35kg, for BF 15.55 ± 2.79% and for BMI 25.32 ± 0.98 kg/m2. In dynamometric tests, the mean values were obtained for VJ height of 27.85 ± 6.02 cm, for CMJ height the value of 28.07 ± 2.74 cm and for SJ height the value of 27.42 ± 2.67 cm. The mean value for the maximum oxygen consumption VO2max was 49.32 ± 2.32 ml / kg / min, and for the total distance traveled was obtained, 1714.28 ± 208.7 m.
Conclusions: Analyzing the data obtained and by comparison with international average reference values, it can be concluded that a specific physical training regime based on the level and position of the player on the field is needed to improve the technical procedures during the match and prevent injuries.
