Warm-up stretching exercises and physical performance of youth soccer players.

This study aims to compare the effects of standard warm-up versus warm-up using stretching exercises on the physical performance of male youth soccer players. Eighty-five male soccer players (age: 10.3 ± 4.

Can strength exercise affect the muscle oxygen saturation response?

Purpose: The objective of the study was to describe and compare the acute response of muscle oxygen saturation (SmO2) and hemoglobin concentration (Hgb) in the vastus lateralis (VL) during resistance exercise protocols until failure.

Methods: Sixteen males were considered (mean ± SD, age = 36.12 ± 6.

Similar Metabolic Health in Overweight/Obese Individuals With Contrasting Metabolic Flexibility to an Oral Glucose Tolerance Test.

Low metabolic flexibility (MetF) may be an underlying factor for metabolic health impairment. Individuals with low MetF are thus expected to have worse metabolic health than subjects with high MetF. Therefore, we aimed to compare metabolic health in individuals with contrasting MetF to an oral glucose tolerance test (OGTT).

Nonalcoholic fatty liver disease and sarcopenia: pathophysiological connections and therapeutic implications.

Introduction: Nonalcoholic fatty liver disease (NAFLD) is currently one of the most common liver diseases worldwide. Recent data suggest that loss of skeletal muscle mass and function (i.e.

Direct Relationship Between Metabolic Flexibility Measured During Glucose Clamp and Prolonged Fast in Men.

Objective: This study aimed to determine the relationship between metabolic flexibility (MetFlex) measured during a euglycemic-hyperinsulinemic clamp and a prolonged fast. This study also analyzed the association between MetFlex and metabolic health.

Methods: Eighteen healthy men (mean [SD]: 22 [2] years old; BMI: 22 [1] kg/m ) performed two sessions: (1) euglycemic-hyperinsulinemic clamp (2 mIU/kg of insulin per minute) and (2) ~20-hour fast.

Reliability of NIRS portable device for measuring intercostal muscles oxygenation during exercise.

This study assessed the intra-individual reliability of oxygen saturation in intercostal muscles (SmO-) during an incremental maximal treadmill exercise by using portable NIRS devices in a test-retest study. Fifteen marathon runners (age, 24.9 ± 2.

[Anthropometric differences per playing position in Chilean professional footballers].

Introduction: given the characteristics of soccer, the tendency in the selection of these athletes and their allocation in certain game positions has been conditioned by the morphological characteristics that they present, so that the knowledge of anthropometric particularities by playing position is a relevant antecedent for the technical bodies of professional football. The objective of the present investigation is to identify and compare the anthropometric characteristics by playing position of Chilean professional soccer players. Methods: a total of 390 professional male soccer players, from 15 Chilean professional clubs, were evaluated morphologically by means of the measurement of 25 anthropometric variables, with which the body composition, the somatotype and the Z-score of Phantom were estimated.

[Cardiometabolic risk and variation of fat/adipose content according to body mass index in children from six to nine years old].

Introduction: child excess weight has been associated with obesity in adulthood and, as a consequence, increased risk of death due to cardiometabolic factors. Objective: to identify whether BMI reflects changes in the content and distribution of fat/adipose tissue and the cardiometabolic risk in children between six and nine years old. Material and methods: participants were 537 children (59.

Effects of Physical Activity Governmental Programs on Health Status in Independent Older Adults: A Systematic Review.

This systematic review analyzes the evidence of the effects of physical activity governmental programs oriented toward the health of independent older adults. Medline, Web of Science, PsycINFO, and Psychology & Behavioral Sciences Collection databases were used for data mining, and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols recommendations were followed. Five studies (n = 2,545 participants) fulfilled the established inclusion criteria.

[Association between health anthropometric indexes with physical fitness in physically active elderly women].

Objective: To associate health anthropometric indexes with physical fitness of elderly women (EW) who participate in physical exercise workshops.

Materials And Methods: 272 Chilean women over 60 years took part in the study. The variables studied were BMI, waist circumference (WC), waist-height index (WHI) and physical fitness (PF).

[Relationship between anthropometric health indexes with food consumption in physically active elderly].

Introduction: Programs focused on active aging do not always have actions to guide the elderly about healthy eating. Therefore, the concordance between the feeding habits and the morphological characteristics of this population group is little known.

Objective: To correlate the anthropometric health indexes with the frequency of food consumption in physically active elderly (PAE).

Association between anthropometric characteristics and the motor function in Chileans subjects with different levels of physical activity.

There is little information about the relationship bet- ween anthropometric indexes and motor function in active and inactive subjects. In that sense, this research aims todetermine the relationship between anthropometric characteristics and motor function score in Chilean subjects with different levels of physical activity. The sample included 63 subjects (20 women), allocated into three groups:physically active group (GFA, n=21), athlete group (GD, n=21) and physically inactive group (GFI, n=21).

Introducción: la categorización del estado nutricional a través del índice de masa corporal (IMC) es uno de los recursos de valoración clínica más utilizados en el síndrome metabólico (SM). Sin embargo, es desconocida su capacidad para identificar las diferencias en la composición corporal.Objetivo: determinar si las variaciones en el estado nutricional se reflejan en la composición corporal en mujeres con SM e identificar la concordancia de clasificación del riesgo cardiometabólico entre el estado nutricional e índices antropométricos.

Introducción: dado el incremento del sobrepeso y obesidad infantil, es relevante estudiar no solo las consecuencias metabólicas, sino también aquellas de índole musculoesqueléticas que pueden afectar la funcionalidad motriz, como es el pie plano, en esta población. Objetivo: identificar la asociación entre el estado nutricional y la prevalencia de pie plano en niños y niñas chilenos de 6 a 10 años. Métodos: el z-score del índice de masa corporal (IMC) y el registro y análisis de las huellas plantares según la metodología de Hernández-Corvo fue llevado a cabo en 388 escolares (52,3% niñas).
