ABSTRACT Introduction The discussion about the impact on the physical and mental health of obese college students is a current issue. The implementation of “weight loss exercise prescription” seeks to discuss weight loss techniques and their effects, problems most faced by obese girls. Objective Explore the effect of sports intervention on the physical and mental health of obese female students. Methods 20 female college students with simple obesity were selected for an 18-week intervention experiment of fitness exercise associated with long-distance running. The physical and mental health of the volunteers was measured before and after the experiment for statistical analysis. Results After 18 weeks of exercise, it was observed that interpersonal sensitivity, depression, anxiety, and SCL-90 scores decreased significantly, indicating that the implementation of the exercise prescription had a positive impact on the mental health of obese girls. Across the study, compared to a single exercise method, associated aerobic exercise had a significant effect on improving BMI indicators, body weight, and body fat rate in obese adolescent girls. Conclusion By prescribing exercise for weight loss, one can significantly improve the cardiopulmonary function of obese college students and promote physical health, manifesting in the indices of vital capacity and cardiopulmonary function. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

RESUMEN Introducción El debate sobre el impacto en la salud física y mental de las estudiantes universitarias obesas es un tema de la actualidad. A través de la aplicación de la “prescripción de ejercicios para adelgazar”, se pretende debatir temas sobre las técnicas de adelgazamiento y sus efectos, los problemas a los que más se enfrentan las chicas obesas. Objetivo Explorar el efecto de la intervención deportiva sobre la salud física y mental de las estudiantes obesas. Métodos Se seleccionaron 20 estudiantes universitarias con obesidad simple para un ensayo de intervención de 18 semanas de ejercicio físico asociado a carreras de larga distancia. Para el análisis estadístico se midió la salud física y mental de los voluntarios antes y después del experimento. Resultados Tras 18 semanas de ejercicio se observó que las puntuaciones de sensibilidad interpersonal, depresión, ansiedad y SCL-90 disminuyeron significativamente, lo que indica que la aplicación de la prescripción de ejercicio tuvo un impacto positivo en la salud mental de las chicas obesas. En todo el estudio, en comparación con un único método de ejercicio, el ejercicio aeróbico asociado mostró un efecto significativo en la mejora de los indicadores del IMC, el peso corporal y el índice de grasa corporal en chicas adolescentes obesas. Conclusión Mediante la prescripción de ejercicio para la pérdida de peso, se puede mejorar significativamente la función cardiopulmonar de las estudiantes universitarias obesas y promover la salud física, resultado que se manifiesta en los índices de capacidad vital y función cardiopulmonar. Nivel de evidencia II; Estudios terapéuticos - investigación de los resultados del tratamiento.

RESUMO Introdução A discussão sobre o impacto na saúde física e mental de estudantes universitárias obesas é um tema atual. Através da implementação da “prescrição de exercícios de emagrecimento”, busca-se discutir tópicos sobre as técnicas de perda de peso e seus efeitos, problemas mais enfrentados pelas meninas obesas. Objetivo Explorar o efeito da intervenção esportiva sobre a saúde física e mental das estudantes obesas. Métodos 20 estudantes universitárias com obesidade simples foram selecionadas para uma experiência de intervenção de 18 semanas de exercício físico de aptidão física associada a corrida de longa distância. A saúde física e mental das voluntárias foi medida antes e depois do experimento para uma análise estatística. Resultados Após 18 semanas de exercícios observou-se que a sensibilidade interpessoal, a depressão, a ansiedade, e a pontuação de SCL-90 diminuíram significativamente, indicando que a implementação da prescrição de exercícios teve um impacto positivo sobre a saúde mental das meninas obesas. Através do estudo, comparado com um único método de exercício, o exercício aeróbico associado apresentou um efeito significativo na melhoria dos indicadores de IMC, no peso corporal e na taxa de gordura corporal das adolescentes obesas. Conclusão Através da prescrição de exercício para perda de peso, pode-se melhorar significativamente a função cardiopulmonar de estudantes universitárias obesas e promover a saúde física, resultado manifestado nos índices de capacidade vital e função cardiopulmonar.

ABSTRACT Sugarcane (Saccharum L. spp. hybrids) is a globally important crop. While roots contribute to its net primary production, knowledge of sugarcane root growth is incomplete and limited in scope. The objective of this study was to determine cumulative root density (LA), root distribution, effective rooting depth (ERD), and root growth rate for four sugarcane genotypes across three crop cycles (plant cane [PC], first ratoon [FR], and second ratoon [SR]). The experiment was conducted in a rain shelter on four sugarcane genotypes (ROC22, YZ04-241, YZ05-194, and YZ05-51) using minirhizotron tubes to a soil profile depth of 1.08 m. Most roots in were found at 0–0.36 m-depth, and about 85.0% were within a 0–0.72 m depth in PC. In FR and SR, however, > 81.8% of roots were found at 0–0.54 m-depth regardless of genotype. The LA of ROC22 was often significantly higher than that of the other genotypes at depths < 0.54 m regardless of crop cycle. The genotype ROC22 had greater root length and faster root growth rate than YZ05-194 at 0.18–0.36 m in PC and FR, while SR YZ05-194 had slower root growth than the other genotypes at 0–0.18m. Ratooning ability of sugarcane genotypes may be related to these root growth attributes.

OBJECTIVES: Remote ischemic perconditioning is the newest technique used to lessen ischemia/reperfusion injury. However, its effect in hypertensive animals has not been investigated. This study aimed to examine the effect of remote ischemic perconditioning in spontaneously hypertensive rats and determine whether chronic treatment with Olmesartan could influence the effect of remote ischemic perconditioning. METHODS: Sixty rats were randomly divided into six groups: vehicle-sham, vehicle-ischemia/reperfusion injury, vehicle-remote ischemic perconditioning, olmesartan-sham, olmesartan-ischemia/reperfusion and olmesartan-remote ischemic perconditioning. The left ventricular mass index, creatine kinase concentration, infarct size, arrhythmia scores, HIF-1α mRNA expression, miR-21 expression and miR-210 expression were measured. RESULTS: Olmesartan significantly reduced the left ventricular mass index, decreased the creatine kinase concentration, limited the infarct size and reduced the arrhythmia score. The infarct size, creatine kinase concentration and arrhythmia score during reperfusion were similar for the vehicle-ischemia/reperfusion group and vehicle-remote ischemic perconditioning group. However, these values were significantly decreased in the olmesartan-remote ischemic perconditioning group compared to the olmesartan-ischemia/reperfusion injury group. HIF-1α, miR-21 and miR-210 expression were markedly down-regulated in the Olmesartan-sham group compared to the vehicle-sham group and significantly up-regulated in the olmesartan-remote ischemic perconditioning group compared to the olmesartan-ischemia/reperfusion injury group. CONCLUSION: The results indicate that (1) the protective effect of remote ischemic perconditioning is lost in vehicle-treated rats and that chronic treatment with Olmesartan restores the protective effect of remote ischemic perconditioning; (2) chronic treatment with Olmesartan down-regulates HIF-1α, miR-21 and miR-210 expression and reduces hypertrophy, thereby limiting ischemia/reperfusion injury; and (3) recovery of the protective effect of remote ischemic perconditioning is related to the up-regulation of HIF-1α, miR-21 and miR-210 expression.
