ABSTRACT
The aim of this study was to identify the existence of some relationships between certain psychomotor behaviors, which we consider specific to swimming, and learning to execute the technique of some swimming styles (front crawl and backstroke). The study was carried out for 10 months and included 76 children (40 boys and 36 girls) aged between 6 and 9 years who practice recreational swimming in a city in Romania. Several tools were used: the Tapping test for manual dexterity, the Goodenough test for body schema, the Flamingo test for static balance, and the horizontal buoyancy test for body balance on the water. The results indicated better ratings on all psychomotor behaviors analyzed according to gender (in favor of girls compared to boys). The levels of all analyzed psychomotor behaviors have a direct relationship to the subjects' age. Also, we identified moderate positive correlations for manual dexterity (rs = 0.63 in the front crawl style; rs = 0.57 in the backstroke style) and strong correlations for body schema, static balance and buoyancy, coordination with the learning of the two swimming styles (r or rs between 0.77 and 0.85). In conclusion, psychomotor behaviors can be predictors for learning swimming styles.
ABSTRACT
Food supplements contain a variety of combinations of vitamins, minerals, plant extracts, and other substances. Any physical effort requires energy from balanced and healthy nutrition. This research aimed to identify the categories of dietary supplements used by active and very active participants who attend the sports and leisure centers from Targu Mures city. The survey was developed in paper and online forms using the Internet and supported multimedia and self-administration. The sample consists of 517 subjects chosen randomly from the research population and divided into the active and highly active PAI subgroups based on age, education, and gender. IBM SPSS Statistics Version 20.0 was used to process the collected data. All data were analysed descriptively. Differences between independent groups were assessed using an Independent sample t-test and a Chi-square test. Statistical significance was accepted when p < 0.05. Additionally, a Pearson correlation was done. The most representative age category was between 18 and 22 years old (42.7%), the ones using dietary supplements most frequently. There were significant differences by group of age regarding the consumption of food supplements (p < 0.05) and also by gender (p < 0.05).
