Differences in anthropometric characteristics and physical capacities between junior and adult top-level handball players
Background: In all age groups of handball players, anthropometric characteristics and physical capacities are important prerequisites to fulfilling the playing demands. However, there is no study that has compared anthropometric characteristics and physical capacities between junior and adult handball players by the same research design containing field tests.
Objectives: This study aimed to investigate differences in anthropometric characteristics and physical capacities between junior and adult top-level handball players using various field tests. Relationships among physical capacities were also examined.
Methods: Ten male junior (18 ± 1 years) and eleven adult (26 ± 1 years) field handball players competing in the U19 Bundesliga and DKB Handball-Bundesliga, respectively, were tested for body height, mass, fat, and fat-free mass as well as 30 m speed and 22 m change of direction (COD), squat jump (SJ) and counter movement jump (CMJ), one repetition maximum (1RM) bench press, core strength-endurance, and interval shuttle run test (ISRT). Magnitude-based inferences, effect sizes (ES), and Pearson correlation coefficients (r) were computed for statistical analyses.
Results: Juniors had a very likely lower body height, mass, and fat-free mass and likely lower 1RM bench press and ISRT performance (ES: 0.7 - 1.2). Contrary, juniors had a likely to very likely superior speed, COD, and SJ and most likely superior core strength-endurance performance (ES: 0.5 - 1.6). While speed, COD, and jump capacities were large to very large correlated in juniors (r = -0.55 - 0.86), they were mostly unclear correlated in adults (r = -0.05 - 0.79). Overall explained variance among speed, COD, and jump capacities was likely higher in juniors (51%) than adults (17%) (ES: 1.7).
Conclusions: This study shows that differences in anthropometric characteristics and physical capacities, and also in relationships among physical capacities, are evident between junior and adult top-level handball players, indicating different physical needs to play handball.
