One-year changes in physical performance in world-class team handball players from Danish national youth teams

The physical part of a team handball game consists of a combination of intense, intermittent activities such as running, sprinting, jumping as well as regular infights between players - holding and pushing. Physical demands in international handball can be evaluated by measuring physical performance of the best players. Describing changes in successful young players indicate which physical factors are the most important to develop. No difference was seen in Body fat, VO2max, Blmax, HRmax, T5m, T30m, CMJ, SST, S3S or SJU (P>0.05), while body weight and fat free mass increased by 1.6 and 2.0 kg or 1.9 and 2.9%, respectively (P<0.01). Tmax, and 30mshuttle increased 22 sec and 354 m or 4.9 and 8.6%, respectively (P<0.05). CMJ½BW increased by 1.4 cm or 9.9% (P<0.001). 1RM increased by 8, 14 and 7 kg or 11, 14 and 9% in power clean, squat and bench press, respectively (P<0.001). Accordingly, after one year of training the players increase body weight and fat free mass and variables related to strength such as CMJ½BW and 1RM in strength exercises. Time to exhaustion in maximal treadmill run and distance covered during shuttle run also increase. However, no changes are seen in functional exercises as 30 m sprint and different shots. Aerobic work capacity per kg body weight is maintained although body weight increases. It is concluded that successful players competing at international level in team handball is depending more on changes in variables alluding to strength properties rather than on variables related to aerobic capacity. Thirty-two players belonging to the national youth teams (Y: 17-18 or U: 19-20 years), age: 18.4±0.7 years, height: 188±6 cm and weight: 83.7±8.4 kg (mean±SD), were tested at least twice for physical performance in February 1997, 1998 or 1999. Y was placed 6 in the European championship in 1998, while U won the world and European championship in 1997 and 1998, respectively. Physical performance parameters were measured during maximal treadmill running: oxygen uptake (VO2max), running time (Tmax), blood lactate (Blmax) and heart rate (HRmax). Furthermore, sprint time over 5 and 30 m (T5m and T30m), counter-movement jump without load and loaded with half the bodyweight (CMJ and CMJ½BW), shooting velocity in 3 shots: standing, after 3 steps and after a jump (SST, S3S and SJU), and a 30 m shuttle run with increasing speeds between markers until exhaustion (30mshuttle) were performed. Strength was evaluated as one repetition maximum (1RM) in power clean, squat and bench press.
