Abstract
The objective of this study was to describe the state of strength and endurance in schoolchildren aged 7 to 10 years old from the city of Santiago de Tolú, Colombia, and to relate such values to their weights, heights, and body mass index (BMI) values. This was a descriptive, correlational, cross-sectional research study, whose quantitative statistical analysis was compared with studies conducted in Colombia and other countries. Strength was measured by the summation of the segmental dynamometry of the upper and lower limbs, and endurance was measured with a 5 min continuous run test. This is the first investigation to characterize variables related to physical education and sport in schoolchildren from Tolú. The information collected on the evaluated population may aid in its sustainable human development, since significant differences in height, weight, BMI, strength, and endurance were identified with respect to other national and international populations.
Highlights
Aerobic capacity has traditionally been used to assess physical health, some studies have stated that it should be complemented with other factors [1] such as muscle condition [2], so that muscle metabolism, strength, and metabolic function can be included in studies aimed at identifying optimal lifestyle behaviors [3].Strength, endurance, and anthropometric variables can be measured to explain the general health state of a population based on the relationship between health and physical education (PE) [4]
The null hypothesis (Ho)—“there are no significant differences in height, weight, Body Mass Index (BMI), strength, and endurance of the population of Tolú from 7 to 10 years old, compared with other national and international populations”—was rejected, which means that the lower conditional and anthropometric values of the variables analyzed in the schoolchildren are evident
The hypothesis that “there is no correlation between BMI and strength” was rejected, and the null hypothesis (Ho) was accepted: “There is no correlation between BMI and VO2max, as an indicator of endurance”
Summary
Aerobic capacity has traditionally been used to assess physical health, some studies have stated that it should be complemented with other factors [1] such as muscle condition [2], so that muscle metabolism, strength, and metabolic function can be included in studies aimed at identifying optimal lifestyle behaviors [3]. Endurance, and anthropometric variables can be measured to explain the general health state of a population based on the relationship between health and physical education (PE) [4]. Deficiencies in cardiorespiratory capacity and muscular strength are associated with an elevated cardiovascular disease risk [5], and corporal composition may be considered a predictor of maximum VO2 in children from 8 to 11 years old [6]. Through a meta-analysis of 1220 abstracts and more than 850 articles, it was concluded that school-aged children should participate daily in at least 60 min of moderate to vigorous physical activity, including a wide range of activities with a duration of at least 30 to 45 min each, three to five days per week, to achieve health goals and benefits [11]
