The study examined the relationships among isokinetic, isometric and dynamic measures of the elbow extensor (EE) and elbow flexor (EF) strength, in junior throwing athletes. The isokinetic torque (T
$_{ISOK}$
)(90, 210, 300°/s) and the isometric torque (T
$_{ISOM}$
)(10, 40, 90°) of the EE and EF, and the maximum force(Fz
$_{max}$
) during the push-up test were measured in tennis(TP, n=7) and handball players (HP, n=8) (13 to 16 yrs). Statistics included 2(Group) × 3 (Angular velocity or Joint angle) ANOVA for group differences and the Pearson coefficient (r) for the relationships between strength measures. Handball players developed higher T
$_{ISOK}$
and T
$_{ISOM}$
(p < 0.05), however, when normalized to body mass, differences were not always significant. Fz
$_{max}$
was the same between groups (p > 0.05). The angle-specificity of the strong relationships between T
$_{ISOK}$
and T
$_{ISOM}$
(p< 0.05) reflected sport specialization. All relationships between EE and EF were significant in TP(p>0.05), whereas, T
$_{ISOK}$
and T
$_{ISOM}$
relationships with Fz
$_{max}$
were significant in HP (p < 0.05). In conclusion, athletic specialization has an impact on the relationships between isokinetic, isometric and dynamic measures of elbow strength in junior tennis and handball players.
