Body Resistance

To determine absolute and relative (adjusted for body mass) strength, mean power, and mean velocity for upper and lower body resistance exercises, forty-seven young boys and girls participated in maximal strength testing. Healthy young boys and girls, ages 3- to 7-years old, were tested for one-repetition maximum (1-RM) strength, and 70% of 1-RM to determine mean power and mean velocity on the chest press and leg press exercises. Adult weight machines were modified to accommodate the smaller size and lower strength levels of the children. A 2 × 4 (sex × age) ANOVA was used to determine age and sex differences in performance. No interaction or sex differences were observed for any variable at any age. 1-RM strength, mean power, and mean velocity significantly increased across ages (p ≤ .05). When adjusted for body mass, the changes were insignificant, with one exception. Relative mean power for the bench press increased with age. Data indicated children from 3-7 years of age are capable of performing strength and power tests, but may require more attempts at maximal loads compared with adults. It appears that muscular strength and velocity during this stage of development are primarily dependent on increasing body mass, whereas power is influenced by additional variable(s).

 El estudio tuvo como objetivo determinar los cambios en la condición física y en el índice de masa corporal que se producen en una intervención de 16 semanas en escolares en . Setenta tres escolares (n=34 niñas; n=39 niños) con edad entre los 8 y 9 años recibieron las siguientes evaluaciones: flexibilidad de la musculatura dorsal de espalda (mediante la prueba de weels), fuerza muscular (mediante la prueba pararse y sentarse), agilidad (mediante la prueba 4x10m shuttle run) y índice de masa corporal (IMC) utilizando un estadiómetro y una balanza. Se aplicó un programa de entrenamiento con ejercicios de flexibilidad, fuerza y resistencia (30 minutos, 5x/semana). Hubo una disminución del IMC (diferencia de 0.60kg/cm2 en ambos géneros), aumento de la fuerza (10.4 repeticiones en niñas y 11.6 en niños) y mejora de la agilidad (0.91 segundos en niñas y 0.71 segundos en niños: p<0.05 en todas las comparaciones y tamaño de efecto entre 0.20-1.77 en niñas y 0.18-2.34 en niños). El índice de obesidad y sobrepeso entre el alumnado de la clase se vio reducido en un 5.3% y 5.9%, respectivamente. No hubo diferencias respecto a la flexibilidad (p>0.05). Un entrenamiento diario en el interior del aula sin implementación y en un espacio de un metro cuadrado , mejora la fuerza de tren inferior y la agilidad en escolares.  Abstract. The objective of the study was to determine the changes in physical condition and body mass index that occur in a 16-week intervention in schoolchildren inside the classroom. Seventy-three schoolchildren (n=34 girls; n=39 boys) between the ages of 8 and 9 received the following evaluations: flexibility of the dorsal back muscles, through the weels test, muscular strength, through the standing and sitting test, agility, through the 4x10m shuttle test run and body mass index (BMI) using a stadiometer and scale. A training program was applied with flexibility, strength and resistance exercises were performed (30 minutes, 5x/ week). There was a decrease in BMI, (difference of 0.60kg/cm2 in both genders), increase in strength (10.4 repetitions in girls and 11.6 in boys) and improvement of the agility (0.91 seconds in girls and 0.71 seconds in boys), p<0.05 in all comparisons and effect size between 0.20-1.77 in girls and 0.18-2.34 in boys. The rate of obesity and overweight among the students in the class was reduced by one 5.3% and 5.9% respectively. There were no differences in flexibility (p>0.05). A daily training in schoolchildren without implementation and in a space of one square meter decreases BMI, improves lower body strength and agility in schoolchildren.

The purpose of this study was to determine where men fall on the motivation continuum based on intuitive eating status and if motivation for physical activity and intuitive eating are correlated. Results indicate that being an intuitive eater was associated with a lower body mass index. In terms of demographic variables, as age increased, intuitive eating status decreased and body mass index increased. Men scored high on the antidieting and self-care subscales of the Intuitive Eating Scale. Men who were classified as intuitive eaters scored higher on the external and introjected regulation of the Behavioral Regulation in Exercise Questionnaire but no significant differences were reported by eating status and the identified and intrinsic motivation subscales. Intuitive eating holds promise as a weight management and weight loss tool for men. Intuitive eating may also influence initial motivation for physical activity for men.
