About

The heart rate variability is a tool used to asses non-invasive cardiac autonomic. In fact, many studies have been disseminated of heart rate variability in adults, however few results in a literature this parameters in pediatric population, mainly with children submitted the physical training. Thus, this Project aims to verify the effects of aerobic training, with 10 weeks, in prepubertal on the performance and heart rate variability in rest.

Full description

The randomized control trial in accordance with Consort - Statement (Moher et al., 2012) will be done. Will be included 160 children, 80 in an experimental group and 80 children with no intervention, of both genders.

Enrollment: 160 patients

Sex: All

Ages: 7 to 9 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Children be with body weight and height between the 10th and 90th percentiles, according to criteria adopted by the Centers for Disease Control and Prevention (CDC, 2002).
• To characterize the infant state, all volunteers will conduct evaluation of secondary sexual characters by criteria of Tanner (Marshall and Tanner, 1970), through visual inspection by a single experienced paediatrician. Children must show the initial stage of pubertal development, for girls (1 breast) and boys (genital 1) to be included and characterized such prepubertal. Participants throughout the trial entering puberty will be excluded from the final analysis.
• The children will be healthy, without clinical or historical evidence of cardiovascular disease, hypertension, insulin-dependent diabetes mellitus or obesity, and were not taking any drugs.

Exclusion criteria

• The participants can be not linked to sports practices at least one year before the beginning the study, and can be involved only with the physical education classes two times a week for 50 minutes each class.

Intervention: Aerobic Training

Experimental group

Description:

The children included in the experimental group will make 10 weeks of aerobic training. The intensity of the race will be based on individual speed obtained in the last stage completed the progressive test, known as the maximal aerobic speed (MAV) in km/h. The running speed of the exercise protocol will be minimum 80% of the MAV in the protocol of continuous training. The intermittent progressive training is n \* (10\*15 s) to 100% MAV, and n from 2 to 6 series between the first and tenth week. The training protocol was adapted from previously described (Mandigout et al, 2002, Gamelin et al, 2009.). Acceptance of the exercise in a pediatric population has been previously observed by pilot study.
