The recommended amount of physical activity, sedentary behavior, and sleep duration for healthy Saudis: A joint consensus statement of the Saudi Public Health Authority.

Background: The goal of the 24-h Movement Practice Guidelines for Saudi Arabia is to provide policymakers, health-care providers, researchers, sports professionals, and members of the public with recommendations on the duration of time they should spend engaged in physical activity, sedentary behavior, and sleep throughout all age groups.

Methods: A modified RAND appropriateness method and the "GRADE-ADOLOPMENT" approach of guideline recommendations were used by a guideline development panel to develop the present recommendations.

Results: The recommendations were based on the integrated needs of the following age groups: children (0-2 years), preschoolers (3-5 years), children and adolescents (6-17 years), adults (18-64 years), and older adults (≥65 years).

Joint consensus statement of the Saudi Public Health Authority on the recommended amount of physical activity, sedentary behavior, and sleep duration for healthy Saudis: Background, methodology, and discussion.

The Saudi Public Health Authority recently prepared a Consensus Statement regarding how much time a person should spend engaged in physical activity, sedentary behavior, and sleep to promote optimal health across all age groups. This paper describes the background literature, methodology, and modified RAND Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation (GRADE)-ADOLOPMENT approach that guided the development process. A Leadership Group and Consensus Panels were formed, and credible existing guidelines were identified.

Determining the time needed for workers to acclimatize to hypoxia.

This study aimed to determine the influence of intermittent hypoxia and the days required for a worker to be acclimatized in high-altitude countries. We conducted an experimental study. Ten nonsmoking male students were randomly recruited from King Saud University.

Effect of Ambient Oxygen Content, Safety Shoe Type, and Lifting Frequency on Subject's MAWL and Physiological Responses.

Objective: The purpose of this study was to evaluate the lifting capabilities of individuals in hypoxia when they wear different types of safety shoes and to investigate the behavior of the physiological responses induced by the lifting process associated with those variables.

Methods: An experimental design was used, based on two sessions. The first was training and acclimatization session, then an experimental lifting phase.
