I present a nice search for a Finnish study group, which analyzing the trend of the Finnish population (we Italy are “precursors” in this …) have coddled this important and curious study.
PURPOSE: To study how time spent doing physical activity and watching television (TV) is associated with muscle fitness levels in adults.
METHODS: The population involved in this study consisted of 381 males and 493 females (mean age 19.1 years; SD 0.3). Muscle fitness levels were measured by tests for the strength of the trunk musculature (flexion, extension and rotation of the trunk) and of the jump tests. Through the self-administration of a questionnaire, the time spent performing moderate and intense physical activity and the one spent watching TV was evaluated.
RESULTS: The physically most active young people achieved statistically significant results better than those of the less active (and so far there …). The average difference between the plus and the least active in the execution of the different tests of strength of the trunk was between a minimum of 1.6 kg (95% confidence interval (CI) = from -0.5 to 3.7) to a maximum of 10.6 kg (95% CI = 4.7-16.5) and 4.4 cm (95% CI 2.7-61). Men and women who watch TV for more than 2 hours a day have achieved significantly worse results during physical testing. The average difference in the strength of the extension of the trunk between the boys who watch little or much TV was 3.8 Kg (95% CI = -6.7 to -0.9) and -1.2 cm (95% CI -2.0 to 0.4) regarding jump height in women. CONCLUSIONS: Among the boys, the daily vision of TV for more than 2 hours, regardless of the type of physical activity performed, has been associated with lower fitness levels.
