Each day whole blood was collected and on the fifth day another 6 samples were taken each hour after BJ intake. One additional sample was collected 24 hours after intake as wash-out period. •Commercially available supplements and biochemical kits were used for the purposes of the study. •Gathered data are also crucial for setting the proper methods in main research with focus on increasing athlete‘s muscle work efficiency and therefore performance during submaximal cycling test. ̶ Nitrate/nitrite blood dynamics after beetroot juice concentrate intake Adobe Systems Faculty of Sports Studies, Masaryk University, Brno, Czech Republic 10 Biomotor Abilities – research 1 The influence of length of rest interval and age on change dynamic in strength parameters •Aim: to find out whether children will be able to achieve the required performances with a shorter rest interval than adults? •shorten the total time of the strength intervention and provide more space for the development of necessary technical and tactical skills, or create an oportunity to use strength training in normal physical education classes. •20 children (10 girls, 10 boys) and 20 adults (10 men and 10 women). Children and adults perform 3 series of 10 RM free-weight squats (resistence chosen on safety basis for children) in six not consecutive days (combination of 2 types of rest - active, passive and 3 rest intervals (IC), IC: 3min, IC: 2min, IO: 1min). The order of combinations is random for each person. •The ability to produce strength (repetition rate, execution speed, muscle strength, and work) is recorded using the instrument FytroDyne. •record the heart rate using sporttest and analysis of respiratory parameters by CORTEX.

Children exercise twice a week for 11 weeks •The exercise lasts 60 minutes in a range of 2 training units per week (15 min warm up and stretching, 40 min exercise, 5 min stretching). •Exercise is focused to practicing large muscle groups (squat, leg press, bench press, pull-ups with expander, abdomen exercise). •Resistance increases during the weeks from 12Rm to 8Rm. The effectiveness of the exercise will be evaluated by comparing the input and output InBody.
