Effects of a 12-week-long program of vigorous-intensity physical activity on the body composition of 6-and 7-year-old children

Abstract

The purpose was to study the effects of a program of vigorous-intensity physical activity (PA) on the body composition of children. This investigation involved 32 school children from 6 to 7 years old (14 males 6.57 ± 0.51 yr., and 18 females 6.33 ± 0.49 yr.). The variables measured were: body weight, fat-free mass (FFM), fat mass (FM), total body water (TBW), basal metabolic rate (BMR), body mass index (BMI), fat-free mass index (FFMI) and fat mass index (FMI). The body composition analysis was performed using bioelectrical impedance through the body fat monitor Tanita BC 418-MA Segmental. Stadiometer HM -250P Leicester was also used to obtain the height. The procedure was as follows: pre-test, intervention and post-test. The intervention consisted of 3 days per week of vigorous-intensity physical activity, 15 minutes per day, during 12 weeks. Data analysis was performed through SPSS 23 and significant improvements (Sig<0.05) were obtained in all the variables except for BMI. The physical activity program used in this study may be useful to improve body composition in 6-and 7-year-old children.

Levels of Physical Activity Are Associated With the Motivational Climate and Resilience in University Students of Physical Education From Andalucía: An Explanatory Model

“…Among the benefits provided by positive habits figures a decrease in the risk of suffering from diseases such as osteoporosis, cancer or obesity (Warburton and Bredin, 2017). PA produces an improvement in insulin sensitivity, develops cardiorespiratory fitness through adaptations in the cardiovascular system and helps decrease the percentage of fat mass (Fransson et al, 2018; López-Sánchez et al, 2018). In addition, PA also generates a multitude of benefits at a cognitive level, which are the focus of this research work.…”

Is physical activity associated with resting heart rate in boys and girls? A representative study controlled for confounders

“… 23 The intensity of physical activities in adolescents is an important factor for physiological responses, since it was observed that 15 min of vigorous intensity physical activity for three days per week in a 12 week intervention was already able to improve the cardiovascular health of 12–15-year old adolescents. 24 …”

“…Activities with an aerobic predominance have been indicated to ight negative efects of anxiety and slight depressive states (Mc Donald, & Hodgdon, 1991); needing a minimal level or medium grade of activity to achieve a favourable inluence on the symptoms (Annesi, 2000). It has been concluded that physical exercise produces beneicial efects on people's health (Lubans, Foster, & Biddle, 2008;López et al, 2017López et al, , 2018, improving the sensation of wellbeing and mood (Ekkekakis, & Acevedo, 2006).…”
