Soccer Specific Aerobic Endurance Training
The purpose of the is study was to design a dribbling track and a playing session that fulfills the criterion of effective aerobic interval training, and determine whether heart rate is a valid measure of work intensity in soccer specific endurance training (Hoff, Wisloff, Engen, Helgerud, 2002, p.218) Methods
1. Subjects: Six Norwegian athletes who were volunteer first division players whose age was 22.2 ± 3.3 years old. The subjects weight was 77.5 ± 12.4 kg and height was 180.2 ± 5.5cm. (Hoff, Wisloff, Engen, Helgerud, 2002, p.219) 2. Measurements: For the warm up VO2 was measured by placing the subjects on a treadmill with 3 degree incline for 20 minutes. The speed of the treadmill increased 1km/h every minute until VO2 max was met. After VO2 max was reached the subjects were required to run for 2 minutes at intensity level of 50%-60% followed by supramaximal intensity run which caused exhaustion within 3 minutes amongst the subjects. “Heart rate was measured by short range radiotelemetry (Polar Sporttester; Polar Electro,Oy, Finland) during the last minute of running, was recorded as fcmax. Oxygen uptake, ventilation (VE), respiratory exchange ratio (R), and breathing frequency (fb) were measured using an Erogooxyscreen Sprint (EOS; Erich Jaeger)” (Hoff, Wisloff, Engen, Helgerud, 2002, p.219) 3. Experimental Manipulation: There was no set schedule for the field running test measurements. Field running test measurements were performed a minimum of three days and a maximum of nine days after the laboratory test on an indoor high quality soccer field consisting of artificial curled nylon grass filled with sand (Hoff, Wisloff, Engen, Helgerud, 2002, p.219) 4. Statistical Analysis: The statistics that were computed were the correlation between VO2 max and fc at different submaximal velocities during treadmill testing (r=0.844, p<0.01) (Hoff,...
