Reliability and Validity of Low Back Strength/Muscular Endurance Field Tests in Adolescents
نویسندگان
چکیده
Background: Strength, muscular endurance, and fl exibility are important components of healthy back function. This study determined the reliability and evaluated the validity of selected low back fi eld tests (FITNESSGRAM® Trunk Extension [FG-TE] and Box 90° Dynamic Trunk Extension [B-90° DTE]) when compared to laboratory tests (Parallel Roman Chair Dynamic Trunk Extension [PRC-DTE], Parallel Roman Chair Static Trunk Extension [PRC-STE], and Dynamometer Static Back Lift [DSBL]). Methods: Forty males age 15.1 ± 1.2 yr and 32 females age 15.5 ± 1.2 yr participated. Results: Intraclass test-retest reliability coeffi cients (one-way ANOVA model for a single measure) ranged from .940 to .996. Validity coeffi cients determined by Pearson product moment correlation coeffi cients for males and females, respectively, were as follows: B-90° DTE vs. PRC-DTE = .82, .62 (p < .05); B-90° DTE vs. PRC-STE = .55, .38 (p < .05); B-90° DTE vs. DSBL = –.29, –.23; FG-TE vs. PRC-DTE = .23, –.11; FG-TE vs. PRC-STE = –.15, .33; and FG-TE vs. DSBL = –.04, –.36. Conclusions: B-90° DTE was shown to be a valid fi eld test when compared to PRC-DTE, but only for the males. Further research on the PRC-DTE and PRC-STE items for adolescents is recommended.

Relationship of timed sit-up tests to isokinetic abdominal strength.
Article: Sit-up tests have been included in most youth and adult fitness test batteries. One logical reason for their inclusion is the possible relationship between poor abdominal strength and the incidence of low back pain. Therefore, a number of timed field tests have been proposed to measure abdominal function. However, the published data on the validity of field test measures are sparse. Th...
