Study on professional football players – factors in recovery and preparation and performance markers during scheduled training session
ABSTRACT
Purpose. The purpose of the present study is to estimate if the athletes can satisfy their energy needs by diet, if they are well hydrated before training, and if the training is effective.
Methods. Ten players of the football team in the B professional league participated in the study (age 23.44 ± 5.98 years, weight 70.64 ± 4.57 kg, height 176.4 ± 7.35 cm; ±SD). Their body composition was analyzed with the Body Composition Analyzer IoI 353 and they completed food questionnaires. Blood lactate concentrations were determined using the biochemical analyzer BIOSEN – C Line, EKF Diagnostic. The heart rates of the subjects are recorded using the activePULS, MEDION AG. Data was processed using SPSS and Graphpad Prism software.
Results. According to the data obtained from the food questionnaires all subjects received the necessary amount of energy to fully meet their energy needs. From the multiple linear regression, it is seen that the highest value has the standardized coefficient in front of the carbohydrate intake which means that it has the greatest influence (about 65%) on total energy intake. The heart rates of participants in the study range from 78 to 90% of the predicted maximum, i.e., high intensity. Differences in blood lactate concentration before and after exercise are significant, evidence of effective performance on training.
Conclusions. We can conclude that according to the nutrition questionnaire the athletes received a sufficient amount of macronutrients and sufficient amount of energy for their training needs. The change in blood lactate concentrations and heart rate during training is indicative of the responsible attitude of the players, and therefore the target endurance is most likely to be achieved.
Applications in Sport. Reported methods could be a useful tool for coaches to track the recovery and preparation of the athletes in season and to evaluate their performance during a scheduled training session.
