Validity and reliability of a smartphone application for knee posture quantification and the effects of external markers on the precision of this measure.

Background: Technological resources, such as smartphones can contribute to the quantitative assessment of posture.

Purposes: Test the validity and reliability of using a postural assessment application to quantify the frontal plane knee posture in orthostatism and to test the influence of the use of external markers on the precision of this measure.

Design: Methodological study.

Normative reference values for handgrip strength, shoulder and ankle range of motion and upper-limb and lower limb stability for 137 youth judokas of both sexes.

Objectives: To provide reference values for handgrip strength, shoulder and ankle range of motion (ROM) and upper-limb and lower limb stability for youth judokas of both sexes and investigate the effects of sex and side dominance.

Design: Cross-sectional.

Methods: A total of 137 youth judokas from under-18 (n=60) and under-21 (n=77) categories of both sexes were assessed.

Effects crude protein levels on female Nile tilapia (Oreochromis niloticus) reproductive performance parameters.

The goal of the present work was to study the reproductive performance of Nile Tilapia (Oreochromis niloticus) female broodstock fed diets containing different levels of crude protein (CP). Two hundred and forty Nile tilapia (O. niloticus) were used at an average age of 30 months, with 180 females and 60 males.
