IRCT20180607039995N1 IRCT 2020-04-28 Physical Education and Sports Science, University of Tehran Effect of the carriage of tow types of pack on schoolchildren The effects of backpack and modified pack carriage in different weights on posture, kinematics and kinetics of gait in schoolchildren 2018-05-27 anticipated 30 Complete https://irct.ir/trial/31886 interventional Randomization: N/A, Blinding: Single blinded, Placebo: Not used, Assignment: Crossover, Purpose: Other, Blinding description: Prior to measurement, each participant's data sheet was coded without specification, and all measurement interventions were randomly assigned to each participant in the sheet and each intervention was numbered. Each number is issued by the technician of the device, respectively. Therefore, the researcher and evaluator and data analyzer until the end of the analysis process in SPSS is unaware from the nature of the data and their relationship to the repetition. N/A Backpack, modified pack, gait, posture, kinetics, kinematics, pack position. Intervention 1: Control group: walking no load on level surface. Intervention 2: Intervention group: walking while carrying a backpack with 7.5% of body weight load. Intervention 3: Intervention group2: walking while carrying a backpack with 10% of body weight load. Intervention 4: Intervention group3: walking while carrying a backpack with 12.5% of body weight load. Intervention 5: Intervention group4: walking while carrying a backpack with 15% of body weight load. Intervention 6: Intervention group5: walking while carrying a modified pack with 7.5% of body weight load. Intervention 7: Intervention group6: walking while carrying a modified pack with 10% of body weight load. Intervention 8: Intervention group7: walking while carrying a modified pack with 12.5% of body weight load. Intervention 9: Intervention group8: walking while carrying a modified pack with 15% of body weight load. Intervention 10: Intervention group9: walking while carrying a backpack with 10% of body weight load, on thoracic position. Intervention 11: Intervention group10: walking while carrying a modified pack with 10% of body weight load, on thoracic position.
