The aim of this study was to identify the key physical indicators that affect game performance of male team handball athletes in national team handball tournaments and explore them further in relation to playing positions. A total of 150 male handball athletes were tested before a national tournament, using squat, bench press, 30-m sprint, vertical jump, pull-ups and abdominal endurance testing. Correlation analysis was used to examine the potential relationship between fitness level and tournament ranking. The results revealed significant differences in fitness variables among different playing positions (p < 0.05), excepted abdominal endurance and vertical jump (p > 0.05). 1RM squad performance was associated with team rankings (r = 0.289, p < 0.05). For individual playing positions, bench press of backs correlate with rankings (r = 0.354, p < 0.05). For goalkeepers, ranking was significantly positively correlated with 30-m sprinting (r = 0.604, p < 0.05). No other correlations were found (p > 0.05). To conclude, fitness level is to some extent related to team ranking with higher ranked teams having better scores in some of the fitness tests for all playing positions. The key predictors of performance in sport vary from position to position and practitioners need to differentiate between them to organize strength and conditioning training more precisely. More specialized fitness tests are also needed to assess athletes' competition ability.
