Reliability of the Metabolic Response During Steady-State Exercise at FATmax in Young Men with Obesity.

: In this study we evaluated the reliability of blood lactate levels (BLa), energy expenditure and substrate utilization during prolonged exercise at the intensity that elicits maximal fat oxidation (FATmax). Furthermore, we investigated the accuracy of a single graded exercise test (GXT) for predicting energy metabolism at FATmax. : Seventeen young men with obesity (26 ± 6 years; 36.

The polymorphism T1470A of the SLC16A1 gene is associated with the lactate and ventilatory thresholds but not with fat oxidation capacity in young men.

Purpose: To examine the association of the single nucleotide polymorphism A1470T in the SLC16A1 gene with blood lactate accumulation during a graded exercise test and its associated metaboreflex.

Methods: Forty-six Latin-American men (Age: 27 ± 6 years; Body fat: 17.5 ± 4.

Factors Determining the Agreement between Aerobic Threshold and Point of Maximal Fat Oxidation: Follow-Up on a Systematic Review and Meta-Analysis on Association.

Regular exercise at the intensity matching maximal fat oxidation (FAT) has been proposed as a key element in both athletes and clinical populations when aiming to enhance the body's ability to oxidize fat. In order to allow a more standardized and tailored training approach, the connection between FAT and the individual aerobic thresholds (AerT) has been examined. Although recent findings strongly suggest that a relationship exists between these two intensities, correlation alone is not sufficient to confirm that the intensities necessarily coincide and that the error between the two measures is small.

Association Among Different Aerobic Threshold Markers and FATmax in Men With Obesity.

This work studies the interrelation of the first ventilatory threshold (VT1), the heart rate inflection point (HRIP), and the exercise intensity at which blood lactate started to accumulate (LIAB) or increased 1 mmol∙L-1 above baseline (LT+1.0); and examinee their association with the exercise intensity eliciting maximal fat oxidation (FATmax). Eighteen young men with obesity performed an incremental-load exercise test on a treadmill after overnight fasting.

Biomarkers and genetic polymorphisms associated with maximal fat oxidation during physical exercise: implications for metabolic health and sports performance.

The maximal fat oxidation rate (MFO) assessed during a graded exercise test is a remarkable physiological indicator associated with metabolic flexibility, body weight loss and endurance performance. The present review considers existing biomarkers related to MFO, highlighting the validity of maximal oxygen uptake and free fatty acid availability for predicting MFO in athletes and healthy individuals. Moreover, we emphasize the role of different key enzymes and structural proteins that regulate adipose tissue lipolysis (i.

Exercise Fat Oxidation Is Positively Associated with Body Fatness in Men with Obesity: Defying the Metabolic Flexibility Paradigm.

Obesity is thought to be associated with a reduced capacity to increase fat oxidation in response to physical exercise; however, scientific evidence supporting this paradigm remains scarce. This study aimed to determine the interrelationship of different submaximal exercise metabolic flexibility (Metflex) markers and define its association with body fatness on subjects with obesity. Twenty-one male subjects with obesity performed a graded-intensity exercise protocol (Test 1) during which cardiorespiratory fitness (CRF), maximal fat oxidation (MFO) and its corresponding exercise intensity (FATmax) were recorded.

The Relationship Between the Burnout Syndrome Dimensions and Body Mass Index as a Moderator Variable on Obese Managers in the Mexican Industry.

Burnout syndrome (BS) and obesity are two growing conditions that affect employees' health and company productivity. Recently, several studies have pointed to a possible relationship between both phenomena. However, such a relationship has not been clearly defined.

Association of P10L Polymorphism in Melanopsin Gene with Chronic Insomnia in Mexicans.

The aim of this pilot study was to determine the association of the P10L (rs2675703) polymorphism of the gene with chronic insomnia in uncertain etiology in a Mexican population. A case control study was performed including 98 healthy subjects and 29 individuals with chronic insomnia not related to mental disorders, medical condition, medication or substance abuse. Samples were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

Neoaltar: An interactive multimedia day of the dead experience.

Technology has permeated many aspects of human life, from everyday events, entertainment, learning environments, festivities, even solemn ceremonies; such is the case of the century-old Mexican tradition of Day of the Dead. Altars or offerings as they are sometimes called, are a central part of this celebration; whether they are small homemade shrines or big public installations, they are a narrative medium to tell the life-story and honor the memory of a beloved or important individual. This paper presents the creation of a traditional and technologically enhanced offering dubbed Neoaltar, from the identification and classification of narrative elements found in traditional altars, the proposal of an interactive multimedia interface based on a user experience model, and the construction, installation, live demonstration and evaluation of the altar.

Polymeric Nanocomposites Membranes with High Permittivity Based on PVA-ZnO Nanoparticles for Potential Applications in Flexible Electronics.

This study reports the optical, structural, electrical and dielectric properties of Poly (vinyl alcohol) thin films membranes with embedded ZnO nanoparticles (PVA/ZnO) obtained by the solution casting method at low temperature of deposition. Fourier Transform Infrared spectra showed the characteristics peaks, which correspond to O⁻H and Zn⁻O bonds present in the hybrid material. The X-ray diffraction patterns indicated the presence of ZnO structure into the films.

Ergonomic assessment for the task of repairing computers in a manufacturing company: A case study.

Background: Manufacturing industry workers who repair computers may be exposed to ergonomic risk factors.

Objectives: This project analyzes the tasks involved in the computer repair process to (1) find the risk level for musculoskeletal disorders (MSDs) and (2) propose ergonomic interventions to address any ergonomic issues.

Methods: Work procedures and main body postures were video recorded and analyzed using task analysis, the Rapid Entire Body Assessment (REBA) postural method, and biomechanical analysis.

Malnutrition risk factors among the elderly from the US-Mexico border: the "one thousand" study.

Background: The Mexican population is aging, which makes the fact that there is no regional information on the health of the elderly, including those in the northern region of the country.

Objective: To examine nutritional, functional, and cognitive impairments, as well as depression, in non-institutionalized elderly Mexicans along Mexico's northern border.

Design: Observational, descriptive and cross-sectional study.

Software development for the evaluation of the ergonomic compatibility on the selection of advanced manufacturing technology.

Advanced Manufacturing Technology (AMT) is one of the most relevant resources that companies have to achieve competitiveness and best performance. The selection of AMT is a complex problem which involves significant amount of information and uncertainty when multiple aspects must be taken into consideration. Actual models for the selection of AMT are found scarce of the Human Factors and Ergonomics perspective which can lead to a more complete and reliable decision.
