ABSTRACT
RESUMEN Los objetivos de este estudio fueron determinar y comparar el riesgo cardiovascular (RCV) en estudiantes de la carrera de preparador físico de las generaciones 2017 y 2019. Las variables medidas fueron peso corporal (PC), estatura (ES), circunferencia de cintura (CC), índice de masa corporal (IMC) e índice de cintura/estatura (ICE). Se utilizó al CC e ICE para la determinación del RCV y su posterior comparación. La metodología utilizada corresponde a un estudio cuantitativo, transversal, descriptivo: con una muestra de 324 participantes (año 2019 = 98 hombres y 62 mujeres; año 2017 = 103 hombres y 61 mujeres). Se utilizó una báscula mecánica con estadímetro marca DETECTO (para PC y ES) y una cintra métrica antropométrica SECA (para CC). Para las diferencias estadísticas se utilizó la prueba de ANOVA de dos vías y comparaciones múltiples de Sidak, se consideró el índice de D Cohen para el tamaño de efecto, con un alfa de 0.05), ni tampoco se clasifican como grupo de riesgo. Se concluye que las mujeres estudiantes tienen características antropométricas diferentes entre ambos años y que la generación del año 2019 presenta RCV.
ABSTRACT The aims of this study were to determine and compare the cardiovascular risk (CVR) in students of the physical trainer career of the 2017 and 2019 generations. The variables measured were body weight (BW), height (HE), waist circumference (WC), body mass index (BMI) and waist to height ratio (WHtR). The WC and WHtR were used to determine the CVR and its subsequent comparison. The methodology used corresponds to a quantitative, cross-sectional, descriptive study: with a sample of 324 participants (year 2017 = 103 men and 61 women; year 2019 = 98 men and 62 women). A mechanical scale with a DETECTO brand stadiometer (for BW and HE) and a SECA anthropometric tape measure (for WC) were used. Sidak's two-way ANOVA test and multiple comparisons were used for statistical differences, the Cohen D index for effect size was considered, with an alpha of 0.05), nor are they classified as a risk group. It is concluded that female students have different anthropometric characteristics between both years and that the generation of 2019 presents CVR.

Fifteen young males (mixed ages) from the BON herd of University of Antioquia were selected and followed weekly from August to December 1998 (Comprising a range from 9,9 to 28,1 months, from 19 time points of data collection) in order to measure and evaluate: 1) Body and Testicular traits (n = 322); 2) Libido testing (LibT, n = 19); 3) Response to rectal palpation of seminal vesicles reflex (SVR, n = 244); and 4) Analysis of semen collected by artificial vagina (n = 42). Data of physical traits were categorized monthly from 10 to 27 months (n = 17 groups); and data of semen were categorized into three groups (16,1 to 21; 21,1 to 24; and 24,1 to 27 months). Simple regression analysis was performed between each trait (dependent variable) and age (independent variable). Multivariate analysis of variance was used to establish differences between groups and monthly reference values for each trait.Physical traits proportionally increased (p<0,01) with age: Body Weight (R2=0,796) and Scrotal Circumference (R2 = 0,672), had the highest correlation coefficients, whereas Body Length (R2 = 0,454), Withers height (R2 = 0,506), Testis Diameter (R2 = 0,415), and Testis Length (R2 = 0,458), had a mild correlation. Higher scores for LibT (more than 5 mating attempts/5 minutes) were always observed. Individual responses to SVR (secretion of pre-seminal fluid, protrusion of penis and complete erection)proportionally increased with age (R2 = 0,539; p<0,01). The youngest age at semen collection was 16,1 months (1,63 x 108 sperm/cc, with >60 por ciento gross and individual progressive motility); however, no correlation was found with age, neither for volume (3,6 ml), nor for pH (6,86) or semen concentration. These results suggest the onset of puberty occurs between 13 and 14 months for this BON herd and confirm previous observations on the high libido of BON males. Reference values are reported for both testicular and body traits. Breeding Soundness Examination rather than merely...
