Comparison of perceptual responses between different upper-body sprint interval exercise protocols.

This study examined the perceptual responses to various upper-body sprint interval exercise (SIE) protocols matched for total work and work/rest ratio. Fourteen active men (24 ± 4 years, BMI = 26.2 ± 2.

Linear and undulating periodized strength plus aerobic training promote similar benefits and lead to improvement of insulin resistance on obese adolescents.

The present study compares the effectiveness of three types of physical training for obesity control in adolescents submitted to a long-term interdisciplinary therapy. Forty-five post-puberty obese adolescents (15-18yo) were randomly placed in three different groups of physical trainings: aerobic training (AT n=20), aerobic plus strength training with linear periodization (LP n=13) and aerobic plus strength training with daily undulating periodization (DUP n=12). The body composition was evaluated by air-displacement plethysmography; the rest metabolic rate was measured by indirect calorimetry; serum analysis was collected after an overnight fasting.

Aerobic plus resistance training improves bone metabolism and inflammation in adolescents who are obese.

Obesity is a worldwide epidemic with a high prevalence of comorbidities, including alterations in bone mineral metabolism. The purpose of this yearlong study was to evaluate the role of 2 types of exercise training (aerobic and aerobic plus resistance exercise) on adipokines parameters and bone metabolism in adolescents who are obese. This was a clinical trial study with interdisciplinary weight loss therapy.

Long-term effects of aerobic plus resistance training on the adipokines and neuropeptides in nonalcoholic fatty liver disease obese adolescents.

Objective: To compare the effects of aerobic training (AT) with aerobic plus resistance training (AT+RT) in nonalcoholic fatty liver disease (NAFLD) obese adolescents.

Design: Long-term interdisciplinary weight-loss therapy (1 year of clinical, nutritional, psychological, and exercise-related intervention).

Participants: Fifty-eight postpubertal obese adolescents were randomized to AT or AT+RT according to NAFLD diagnosis.

The role of nutritional profile in the orexigenic neuropeptide secretion in nonalcoholic fatty liver disease obese adolescents.

Background: Little progress has been made to identify the central neuroendocrine pathway involved in the energy intake control in nonalcoholic fatty liver disease (NAFLD) patients.

Objective: To assess the influence of orexigenic neuropeptides in the nutritional aspects of NAFLD obese adolescents submitted to a long-term interdisciplinary approach.

Methods: Fifty adolescents aged 15-19 years, with body mass index at least 95th percentile, consisting of 25 patients without NAFLD and 25 with NAFLD.

Negative correlation between neuropeptide Y/agouti-related protein concentration and adiponectinemia in nonalcoholic fatty liver disease obese adolescents submitted to a long-term interdisciplinary therapy.

The complexity pathogenesis in the nonalcoholic fatty liver disease (NAFLD) involves an interplay between adipokines and neuroendocrine regulation of energy balance, including the role of neuropeptide Y (NPY)/agouti-related protein (AgRP) system. The first aim of this study was to assess the effect of long-term interdisciplinary intervention on NAFLD in obese adolescents, and the second objective was to establish the relationship between NPY/AgRP ratio and adiponectinemia. Fifty-five postpuberty obese adolescents were submitted to interdisciplinary intervention.

Comparison between linear and daily undulating periodized resistance training to increase strength.

To determine the most effective periodization model for strength and hypertrophy is an important step for strength and conditioning professionals. The aim of this study was to compare the effects of linear (LP) and daily undulating periodized (DUP) resistance training on body composition and maximal strength levels. Forty men aged 21.

Treatment of obese adolescents: the influence of periodization models and ACE genotype.

The aims of the present study were to compare the effects of two periodization models on metabolic syndrome risk factors in obese adolescents and verify whether the angiotensin-converting enzyme (ACE) genotype is important in establishing these effects. A total of 32 postpuberty obese adolescents were submitted to aerobic training (AT) and resistance training (RT) for 14 weeks. The subjects were divided into linear periodization (LP, n = 16) or daily undulating periodization (DUP, n = 16).

Platelet and leptin in obese adolescents.

Objective: To analyze the influence of obesity status on immune cell count and concentration of the hormones cortisol and leptin, in order to establish a relationship among the variables analyzed.

Methods: We recruited 27 obese [body mass index (BMI) > or = 95th percentile] and 21 non-obese (BMI < or = 75th percentile) adolescent boys and girls, aged 15-19 years at the post-pubertal stage. BMI was calculated as body weight divided by height squared, and body composition was estimated by plethysmography in the Bod Pod system.
