ABSTRACT

【Objective】 To explore the mediating effect of different organizational climate on volunteer service motivation and work engagement among volunteers during the COVID-19 epidemic. 【Methods】 The Volunteer Service Motivation Scale, Organizational Climate Scale, and Work Input Scale were used to investigate relevant contents among volunteers from Shaanxi, Hubei and Henan provinces who participated in prevention and control of the COVID-19 epidemic by convenient sampling method. Pearson correlation analysis was applied to explore the correlation among volunteer service motivation, organizational climate and work engagement. The Bootstrap method was used to analyze the mediating role of organizational climate between volunteer service motivation and work engagement. 【Results】 The scores of volunteer service motivation, organizational climate, and work engagement of the 834 volunteers were 72.45±13.66, 24.03±4.65, and 51.59±10.04, respectively. Volunteer service motivation was positively correlated with work engagement (r=0.556, P<0.001) and organizational climate (r=0.604, P<0.001). Organizational climate was positively correlated with work engagement (r=0.632, P<0.001). Organizational climate played a mediating role between volunteer service motivation and work engagement (effect value=0.278, accounting for 47.0% of the total effect). 【Conclusion】 Volunteer service motivation indirectly affects work engagement through organizational climate, indicating that volunteer team managers can improve their work engagement level by improving the organizational climate.

ABSTRACT

ABSTRACT Introduction: The obesity rate of Chinese adolescents has reached an alarming level, where about 11% of Chinese children are overweight, making them more prone to diseases such as hypertension, abnormal physiological metabolism, and high joint wear of the lower limbs. This public health problem can be alleviated with healthy habits, including aerobic exercise. Objective: Study the effect of aerobic exercise on obesity and lipid metabolism in adolescents. Methods: In this randomized controlled trial, 40 young volunteers were equally allocated into experimental and control groups. The control group received no intervention, while the experimental group was trained according to a professionally designed aerobic exercise protocol for 28 days. Training data were recorded before, during, and after the exercises. The information was processed, compared, and analyzed. Results: The control group failed to reduce body fat effectively; an aerobic exercise in the experimental group showed better effects in reducing body weight, body fat, waist-to-hip ratio, and weight loss; compared to the control group. Immediately after the intervention, the HDL level of the experimental group showed an upward trend, while the TC, TG, and LDL indices showed a downward trend. Conclusion: Aerobic exercise can effectively increase muscle mass and basal calorie and fat intake, reducing youth obesity. Level of evidence II; Therapeutic studies - investigating treatment outcomes.


RESUMO Introdução: A taxa de obesidade de adolescentes chineses atingiu um nível alarmante onde cerca de 11% das crianças chinesas estão acima do peso, tornando-se mais propensas a adquirirem doenças como hipertensão arterial, metabolismo fisiológico anormal e elevados desgastes articulares dos membros inferiores. Esse problema de saúde pública pode ser amenizado com hábitos saudáveis, incluindo o exercício aeróbico. Objetivo: Estudar o efeito do exercício aeróbico sobre obesidade e o metabolismo lipídico dos adolescentes. Métodos: Nesse ensaio clínico randomizado controlado, 40 jovens voluntários foram igualmente alocados em grupos experimental e controle. O grupo controle não recebeu intervenção alguma enquanto o grupo experimental foi treinado segundo um protocolo de exercícios aeróbicos elaborado por profissionais durante 28 dias. Foram registrados os dados de treinamento, antes durante e após os exercícios. As informações foram tratadas, comparadas e analisadas. Resultados: O grupo controle não conseguiu reduzir efetivamente a gordura corporal, o exercício aeróbico no grupo experimental apresentou melhores efeitos na redução do peso corporal, gordura corporal, relação cintura-quadril e perda de peso; em comparação com o grupo controle. Imediatamente após a intervenção, o nível de HDL do grupo experimental mostrou uma tendência de alta, enquanto os índices TC, TG e LDL apresentaram tendência de queda. Conclusão: O exercício aeróbico pode efetivamente aumentar a massa muscular, o consumo basal de calorias e gordura, alcançando a redução eficaz da obesidade juvenil. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.


RESUMEN Introducción: La tasa de obesidad de los adolescentes chinos ha alcanzado un nivel alarmante en el que cerca del 11% de los niños chinos tienen sobrepeso, siendo más propensos a adquirir enfermedades como la hipertensión, un metabolismo fisiológico anormal y un elevado desgaste articular de las extremidades inferiores. Este problema de salud pública puede paliarse con hábitos saludables, entre ellos el ejercicio aeróbico. Objetivo: Estudiar el efecto del ejercicio aeróbico sobre la obesidad y el metabolismo lipídico en adolescentes. Métodos: En este ensayo controlado y aleatorizado, 40 jóvenes voluntarios fueron asignados por igual a los grupos experimental y de control. El grupo de control no recibió ninguna intervención, mientras que el grupo experimental fue entrenado según un protocolo de ejercicio aeróbico diseñado por profesionales durante 28 días. Los datos del entrenamiento se registraron antes, durante y después de los ejercicios. La información fue procesada, comparada y analizada. Resultados: El grupo de control no logró reducir eficazmente la grasa corporal, el ejercicio aeróbico en el grupo experimental mostró mejores efectos en la reducción del peso corporal, la grasa corporal, la relación cintura-cadera y la pérdida de peso; en comparación con el grupo de control. Inmediatamente después de la intervención, el nivel de HDL del grupo experimental mostró una tendencia al alza, mientras que los índices de TC, TG y LDL mostraron una tendencia a la baja. Conclusión: El ejercicio aeróbico puede aumentar eficazmente la masa muscular, la ingesta calórica basal y las grasas, logrando una reducción efectiva de la obesidad juvenil. Nivel de evidencia II; Estudios terapéuticos - investigación de los resultados del tratamiento.

ABSTRACT

Objective To explore the relationship among emotional resilience,stress and school adjustment.Methods Adolescent life events check-list,adolescent emotional resilience scale and school adjustment scale of middle school students were conducted among 394 junior high school students.Results (1)The emotional resilience score and emotion recovery score of male junior high school students(46.07±8.56,24.43±5.80) were higher than that of female ones(44.39±8.39,23.27±5.37),and the differences were statistically significant(t=1.97,2.05,P<0.05).The total score of emotional resilience(45.46±8.50,44.83±8.56) was not statistically related with whether they were the only children(t=0.68,P=0.50).The emotional resilience score and positive emotion score of rural junior high school students(44.04±8.53,20.63±5.35)were lower than that of urban ones (46.46± 8.34,22.15 ±4.72),and the differences were statistically significant(t=-2.86,-2.99,P<0.01).The total score of emotional resilience (47.23±7.82,44.63±8.45,43.00±8.97) in different grades was statistically significant (F=8.86,P=0.00),and the first grade students were higher than the second and third year students.(2)Psychological stress was negatively related with emotional resilience and school adjustment(r=-0.23~-0.35,P<0.01),and emotional resilience was positively correlated with school adjustment(r=0.12 ~ 0.29,P<0.01).The relationship between stress and school adjustment were mediated by positive emotion and emotional recovery (the mediating effect were 11.11%,21.15%).Conclusion Frotional resilience plays a mediating role between psychological stress and school adjustment.
