Training A: Strength training for local strength endurance (8 basic tennis exercises, each at 60% of 1 RM, involving arms and shoulders as follows: bench press, dumbbell pullovers, T-bar rows, reverse curls; legs as follows: squats, lunges; trunk as follows: crunches, dumbbell side bends). Training B: line jumps in teams (agility, coordination, rhythm, sense of direction and adjustment abilities; alternatelywith the balance exercises on balls), Training C: swimming: 30-minute exercise, focusing mainly on upper limbs muscles; distance to cover- around 800m) , Training D: stretching exercise, “hold-relax” technique and basic yoga exercises. Training E: conditioning exercise- team sports: soccer - regular match (2 times 45 minutes, 7x7 players), average heart rate at60-95% HR. Training F: regeneration (each player uses 2 hydrotherapy treatments for 40 minutes). Training G: agility games with tennis balls on small (main stress on coordination, agility, accuracy). Training H: interval training (2 series /5-10 second/in 6 repetitions, 80-95% HR, work to rest ratio 1:3) Training I: endurance, continuous distance running for 60 minutes 70 -80% HR. Training J: tennis training (developing tennis memory movement).Training K: conditioning exercise team sports: soccer - short games with short periods (few seconds) with high intensity, average heart rate at 80-95% HR
