Criterion-related validity of field-based muscular fitness tests in youth

The purpose of the present study was to analyze the association between isokinetic strength and field-based muscular fitness tests in youth. One hundred twenty-six adolescents (14.4±1.7 y) participated in the study. Upper and lower body isokinetic strength were measured at preset angular velocities of 90 º/s and 60 º/s, respectively. Muscular fitness was also assessed by means of field-based tests: handgrip strength, bent and extended arm hang tests, standing long jump, squat jump, countermovement jump and Abalakov jump. Height, weight and skinfold thickness were used to estimate body composition. All field-based tests were significantly associated with isokinetic peak torque and power (P
