Abstract:
The COVID-19 pandemic reduced daily physical activity in the pediatric population, with deleterious effects on anthropometry, muscle function, aerobic capacity, and metabolic control.
Objective:
Determine the changes in anthropometry, aerobic capacity, muscle function, and metabolic control of a 12-week concurrent training protocol in overweight and obese children and adolescents during the COVID-19 pandemic.
Patients And Method:
24 patients participated and were divided into groups once a week (12S; n = 10) and twice a week (24S; n = 14). Anthropometry, muscle function, aerobic capacity, and metabolic biochemical tests were evaluated before and after the application of the concurrent training plan. Two-way ANOVA, Kruskal-Wallis test, and Fisher's post hoc test were used.
Results:
Only the twice times week training improved the anthropometrics parameters (BMI - z, waist circumference and waist to height ratio). The muscle function tests (push up, standing broad jump and prone plank), improved in both groups such as the aerobic capacity measured by VO2maximo and the runned distance in Shuttle 20m run test. The HOMA index only improved with twice times week training without changes in lipid profile in both groups.
Conclusions:
The 12S and 24S groups improved aerobic capacity and muscular function. Only the 24S improved anthropometric parameters and the HOMA index.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
