The Effects of the Nocturnal Sleep on Learning of a Complex Motor Skill in Young and Older Adults.

Background/study Context: Research on older adults has shown impairments in nocturnal sleep, impacting motor memory consolidation and learning. However, previous studies primarily focus on simple tasks, limiting generalization to complex motor activities. Moreover, no evidence exists on how sleep influences adaptability and relearning in older adults.

Aerobic training performed at ventilatory threshold improves liver enzymes and lipid profile related to non-alcoholic fatty liver disease in adolescents with obesity.

Background: Despite the positive effects of high-intensity training on weight management and health-related outcomes, it is postulated that high-intensity training may also induce oxidative stress, increasing hepatic damage.

Aim: The aim of this study was to compare the effects of low versus high-intensity training on biomarkers related to non-alcoholic fatty liver disease (NAFLD) in adolescents with obesity.

Methods: For this study 107 adolescents (15 ± 1 years) with obesity (BMI = 34.

Effects of a psychological intervention on the quality of life of obese adolescents under a multidisciplinary treatment.

Objective: To investigate the effects of multidisciplinary treatment with and without psychological counseling on obese adolescents' self-reported quality of life.

Methods: Seventy-six obese adolescents (15.87±1.

Multidisciplinary intervention in obese adolescents: predictors of dropout.

Objective: To identify biological and psychosocial factors associated with dropout in a multidisciplinary behavioral intervention in obese adolescents.

Methods: A total of 183 adolescents (15.4±1.

Somatotype of competitive youth soccer players from Brazil.

The aim of this study was to identify the morphological configuration of youth athletes from professional soccer clubs and to verify their differences according to the tactical position on the field. Overall, 67 male players aged 15 to 17 years were evaluated. The examined anthropometric measurements included body mass, body height, skinfolds (triceps, subscapular, supraspinal and medial calf), girths (flexed and tensed arm and calf) and breadths (humerus and femur).

Morphological characteristics of professional ballet dancers of the Bolshoi theater company.

The objective of this study was to describe the morphological profile ofprofessional dancers compared with university physical education students. Thirty-five subjects were evaluated as follows: 13 professional ballet dancers of the Bolshoi Theater Company, six males and seven females, and 22 university physical education students, 11 males and 11 females. Body mass, height, skinfold (triceps, biceps, subscapular, chest, axilla, supraspinale, Iliac crest, abdominal, Front thigh, medial calf) girth (Arm flexed and tensed, forearm, waist, gluteal girth, Mid-thigh girth and calf) and breadth (wrist, ankle, Biepicondylar humerus and femur) were evaluated and somatotype, body fat percentage (BF%) body mass index (BMI), Sigma7 Skinfolds lean body mass, bone, residual and muscle mass were calculated.
