Selected personal resources and nutritional behaviours of Polish handball players
Abstract
Background. Diet, as one of the factors influencing exercise capacity depends, among others, on individual conditions. Objective. The aim of the study was to analyse the nutritional behaviours of Polish handball players depending on their level of generalised self-efficacy as well as disposable optimism and satisfaction with life. Material and methods. The study was carried out among a group of 142 men, aged 20-34, professionally training handball, using the author’s original nutritional behaviour questionnaire and the Generalised Self-Efficacy Scale (GSES), the Life Orientation Scale (LOT-R) and Satisfaction with Life Scale (SWLS). Statistical analysis of the results was conducted by estimating Spearman’s signed rank correlation coefficients, assuming the significance level of p <0.05. Results. To the highest degree, the handball players fulfilled recommendations regarding the regular consumption of at least 3 meals a day, adequate fluid supplementation in conditions of physical exercise and eating the most caloric meal before or after main training sessions. Along with the increase in sense of efficacy (GSES), the scale of reducing sweet and salty snacks increased (p<0.05). Increasing optimism was conducive to proper hydration (p<0.05) and avoidance of sweet and salty snacks (p<0.05). With the increase in sense of satisfaction with life, the implementation of recommendations regarding the consumption of dairy products and vegetable fats, as well as adequate fluid supplementation in conditions of physical exercise, increased (p<0.05). Conclusion. In the studied group of handball players, a limited scale of implementing qualitative nutritional recommendations for athletes was demonstrated. Moreover, positive correlations were noted between the analysed personal resources and some rational nutritional behaviours of the athletes, especially in terms of avoiding non-recommended products and correct fluid replenishment.
