En esta sección se publican los resúmenes en español de artículos que han sido publicados por investigadoras/es de universidades costarricenses en otras revistas en el mundo, con su debida referencia al trabajo original, y con una breve explicación de dónde se realizó la investigación. Los artículos originales han sido publicados en otros idiomas; las revistas tienen consejo editorial y manejan un proceso de revisión por pares. Los resúmenes corresponden a estudios relacionados con las ciencias del ejercicio y la salud, que se conforman a los criterios generales de la revista, esto es, se trata de "... estudios experimentales o que hagan recomendaciones concretas para solucionar problemas o preguntas relevantes (...) trabajos originales o de meta-análisis." Solicitamos a las personas que han publicado este tipo de trabajos en otros idiomas que no los hagan saber, para incluir sus resúmenes en futuras entregas de esta sección

The consumption of sugar-sweetened beverages has been associated with the onset of cardiometabolic diseases. The aim of this study was to describe consumption patterns of sugar-sweetened and dairy beverages and to evaluate their correlation with the body mass index in children residing at the Mexico–USA border. A total of 722 (370 girls, 352 boys) elementary school children aged 9 to 12 years from Tijuana, Mexico, participated in the study. Anthropometric measures were recorded, and a beverage intake questionnaire was completed by the children’s parents. Significant age by sex interactions were found on body mass index Z-scores (p < 0.01). Boys showed higher sugar intake (p < 0.05) and total relative energy consumption from sugar (p < 0.05) than girls. The energy consumption from sugar-sweetened and dairy beverages was similar between sexes (p > 0.05). Sugar intake from beverages was higher than the limit recommended by the World Health Organization in boys (66%) and girls (44%). A high frequency of consumption of sugar-sweetened beverages and similar intake of dairy beverages were found in children from the Mexico–USA border. The high consumption of sugar exceeds international recommendations and should be carefully monitored.

PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 13 (1), 1-10. Un antitranspirante efectivo es supuestamente capaz de disminuir la sudoración hasta en un 50%, como lo afirman las compañías que fabrican estos productos, pero hay poca evidencia publicada al respecto; es posible que la disminución real sea tan pequeña que no pueda ser detectada por los

Perceived lack of time is one of the most often cited barriers to exercise participation. High intensity interval training has become a popular training modality that incorporates intervals of maximal and low-intensity exercise with a time commitment usually shorter than 30 min. The purpose of this study was to examine the effects of short-term run interval training (RIT) on body composition (BC) and cardiorespiratory responses in undergraduate college students. Nineteen males (21.5 ± 1.6 years) were randomly assigned to a non-exercise control (CON, n = 10) or RIT (n = 9). Baseline measurements of systolic and diastolic blood pressure, resting heart rate (HRrest), double product (DP) and BC were obtained from both groups. VO2max and running speed associated with VO2peak (sVO2peak) were then measured. RIT consisted of three running treadmill sessions per week over 4 weeks (intervals at 100% sVO2peak, recovery periods at 40% sVO2peak). There were no differences in post-training BC or VO2max between groups (p > 0.05). HRrest (p = 0.006) and DP (p ≤ 0.001) were lower in the RIT group compared to CON at completion of the study. RIT lowered HRrest and DP in the absence of appreciable BC and VO2max changes. Thereby, RIT could be an alternative model of training to diminish health-related risk factors in undergraduate college students.
