"Grip-strength ss Associated with Longitudinal Health Maintenance and Improvement in Adolescents…Adolescents who had low NGSs had a significantly greater prevalence of health decline or poor health persistence as compared with those who were strong (boys: 60.2% vs 15.3%; girls: 51% vs 21.9%; all P < .001). Moreover, adolescents who were strong had an increased adjusted odds for health maintenance…and health improvement…even after we adjusted for baseline fat-free mass index, cardiorespiratory fitness, and objectively measured physical activity.

We should get children off video games, and get them outside doing work and having fun. The above study, when read in its fullness, reveals that children should not only be physically active, but active in a way that improves strength - in a healthy way. The glory of a young man is his strength, says Proverbs. We are getting short on glory these days! Even the virtuous woman of Proverbs 31 "strengtheneth her arms" - not in a masculine way, but in a healthy manner. We see young women in the Bible running, and carrying water, and such like. My own children (including teen daughters) jump up and mount bare-back horses to ride, many times a day; they milk cows or goats, and perform all the other duties on a small farm, and a lot of fun. We do not even have video or computer games in our home. May we all do what we can to help children have fun, learn how to work, and yet be healthy in the long run.
