Abstract

Purpose. Energy requirements in sports performance are affected by numerous factors: physical characteristics, age, geneticbasis, sports discipline. The Food and Nutrition Board recommended nutrition based on age, height, and body weight gain inrelation to physical activity. Some genetic factors, such as the PPAR-encoding gene, play a key role in metabolism. The aim ofthe study was to investigate the effect of specific snacks on performance.Methods. Seventeen girls aged 10–14 years practising artistic gymnastics were enrolled. A carb or protein/carb snack was providedbefore the training, and a questionnaire was administered at the end. In addition, saliva samples were collected for genetic analyses.Results. Most girls represented the CC genotype (65%), while a small part had the GC (23%) and GG (12%). The average BMIequalled 20.05 ± 2.8 kg/m2 in the group with the CC genotype, 19.6 ± 2.8 kg/m2 with the GC genotype, and 20.2 ± 2.8 kg/m2with the GG genotype. The questionnaire showed that 59% of girls experienced a performance improvement after eating a carbsnack; slightly different results were observed after the intake of a protein/carb snack: 47% felt more energy and 12% more fatigue.Conclusions. This is a preliminary study that should be deepened by increasing the number of subjects, as well as diversifyingthe type of snacks administered and increasing the time of the study. It is important to be mindful of eating habits and lifestylein order to prevent the onset of overweight.
