“…In the present investigation, in the low intensity test, it was observed that there is a greater hyperthermic tendency in the upper extremities, being more relevant in the shoulder and biceps in the DEC machine and higher in the lower limbs in the BED machine. Thermographic measurements were not made for high intensities, but it would be expected that they would be higher in DEC due to the higher HR value obtained in this modality (Marins et al, 2015). On the other hand, during the established tests, two trends in the temperatures of some regions of the upper body (anterior shoulder, biceps, dorsal and pectoral) are differentiated.…”

The objective of this article was to compare different cardiovascular training machines and their effects on the body, as well as to determine their suitability for people with low intensity or high intensity training needs. A total of 8 physically active and healthy male subjects (mean ± standard deviation; age: 28.45 ± 1.75 years; height: 1.84 ± 0.07 m; body weight 76.42 ± 8.62 kg; body mass index: 25.5 ± 2.6) were evaluated through of an incremental exercise test at different intensities on two different machines: Elliptical Domyos 680 (BED) and Deconstruct Elliptical 331-EF (DEC). To compare both machines against the two mentioned training needs, two different protocols were carried out: Low Intensity Protocol (LIP) and High Intensity Protocol (HIP). In addition, a thermographic analysis was carried out in order to determine the temperature differences reached in the musculature. No significant differences were found in HR and EE (p < .05) between the two machines. However, a greater and more progressive activation of the muscles of the upper extremities was observed in the DEC machine. In the HIP, HR and EE were measured, obtaining significant differences (p < .05) higher in the DEC machine. Therefore, in our comparison, the Deconstruct Elliptical machine produced more appropriate results for both low and high intensity training compared to the Elliptical machine. These results and the novel nature of the Deconstruct Elliptical raise the need for further studies to better understand this machine.

“…Por tanto, las exigencias serían distintas a cualquier otro tipo de estudiante universitario siendo así esperable que los resultados observados en otras investigaciones sean distintos, como en el trabajo de Oliveras et al 2006, en las que se determinó un consumo alto de grasas. Además, los resultados aquí reportados sugieren que los estudiantes evaluados estarían dando más importancia al consumo de carbohidratos y proteínas sobre el de la grasa dietética, posiblemente debido a que en nutrición deportiva se enfatiza el consumo de estos dos macronutrientes, el primero como combustible energético y el segundo por su rol en la reparación y generación de masa corporal (Helms, Aragón & Fitschen, 2014;Marins et al, 2018). Sería por tanto necesario recomendar a los estudiantes evaluados que aumentasen el consumo de grasas saludables no solo para mantener sus niveles de glicemia sino porque además son un componente necesario para una dieta saludable, debido a que proporcionan energía, son imprescindibles para la formación de nue-vas membranas celulares y para la asimilación de algunas vitaminas (Dietitian of Canada, 2006).…”

Los estudiantes universitarios se caracterizan por presentar hábitos alimentarios irregulares y poco saludables. En particular, los estudiantes de Pedagogía en Educación Física son sujetos más activos que otros universitarios, por lo que deberían presentar unos hábitos más saludables que la población general para obtener un óptimo rendimiento físico y académico. Sin embargo, estudios previos a esta investigación señalaron un alto porcentaje de estos estudiantes en hipoglicemia bajo condiciones de ayuno. El objetivo de investigación fue determinar el estado nutricional, la ingesta dietética y el nivel de glicemia de los estudiantes de esta carrera en Temuco (Chile). La muestra incluyó 56 estudiantes de la carrera de Pedagogía en Educación Física de primer (n=30) y tercer (n=26) año. Las variables estudiadas correspondieron al estado nutricional (índice de masa corporal, IMC), glicemia en ayuno e ingesta dietética (registro 24 horas). Los evaluados obtuvieron valores promedios de 23 kg/m2 para el IMC. Se observaron diferencias estadísticamente significativas entre los cursos para la glicemia (p<,05). Destaca el elevado porcentaje de alumnos con un consumo de nutrientes por debajo de sus requerimientos, principalmente respecto a las calorías totales (41%), a las grasas (61%) y a los carbohidratos (25%). Se concluye que la mayoría de los estudiantes evaluados se clasifican en un estado nutricional normal, presentan hipoglicemia y una estrategia alimentaria centrada en una ingesta alta de proteínas.Abstract. University students usually present irregular and unhealthy eating patterns. Physical Education students are more active than other college students. Thus, they should display better healthy habits than the average population, mainly in order to achieve optimal physical and academic performance. However, studies previous to this investigation indicated that a high percentage of these students show hypoglycaemia under fasting conditions. The objective of this study was to determine the nutritional intake and blood glucose levels of university students from Physical Education. The sample included 56 students of Physical Education (Chile), who belonged to the first (n=30) and third (n=26) academic year. Body Mass Index (BMI), fasting blood glucose, and nutritional intake (24-hour dietary recall) were measured in each subject. The students showed an average BMI of 23 kg/m2. Statistically significant differences were observed in the blood glucose levels (p <.05) between students from different academic years. Outcomes highlighted a high percentage of students with dietary intake lower than the total calories (41%), fats (61%), and carbohydrates (25%) required. On the contrary, 50% of the students showed a protein intake higher than 120% of their nutritional requirements. In conclusion, most of the evaluated students were classified with a normal BMI, had hypoglycaemia, as well as a food strategy focused on high intake of proteins.

“…Infrared thermography (IRT) is a non-invasive, radiation-free, and easy-to-apply technology particularly suitable to precisely map the skin temperature (Tsk) through the analysis of thermographic images, which is frequently used for clinical purposes as an auxiliary tool in the process of diagnosis of diseases [1][2][3] and the prevention and rehabilitation of injuries [4][5][6][7]. The procedure is performed using a thermographic camera with a sensor responsible for capturing the heat radiated from the skin's surface and transforming it into a temperature scale.…”

Infrared thermography (IRT) is a technology easy to use for clinical purposes as a pre-diagnostic tool for many health conditions. However, the analysis process of a thermographic image needs to be meticulous to make an appropriate decision. The adipose tissue is considered a potential influence factor in the skin temperature (Tsk) values obtained by IRT. This study aimed to verify the influence of body fat percentage (%BF) on Tsk measured by IRT in male adolescents. A total of 100 adolescents (16.79 ± 0.97 years old and body mass index of 18.41 ± 2.32 kg/m²) was divided into two groups through the results of a dual-energy X-ray absorptiometry analysis: obese (n = 50, %BF 30.21 ± 3.79) and non-obese (n = 50, %BF 11.33 ± 3.08). Thermograms were obtained by a FLIR T420 infrared camera and analyzed by ThermoHuman® software version 2.12, subdividing the body into seven regions of interest (ROI). The results showed that obese adolescents presented lower mean Tsk values than the non-obese for all ROIs (p < 0.05), with emphasis on the global Tsk (0.91 °C) and anterior (1.28 °C) and posterior trunk (1.18 °C), with “very large” effect size values. A negative correlation was observed in all the ROI (p < 0.01), mainly in the anterior (r = −0.71, p < 0.001) and posterior trunk (r = −0.65, p < 0.001). Tables of thermal normality were proposed for different ROIs according to the classification of obesity. In conclusion, the %BF affects the registered Tsk values in male Brazilian adolescents assessed by IRT.
