Answer:

Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL)

Explanation.

Esto debe revertirse, debe ser una disminución del colesterol malo y un aumento del colesterol bueno.

Básicamente, el ejercicio aumenta el HDL y reduce los triglicéridos. En condiciones normales, los ejercicios aeróbicos no reducen el LDL. Sin embargo, cuando se combina con cambios en la dieta y una pérdida de peso bien controlada, el efecto combinado podría reducir el LDL.

En las condiciones estándar, el ejercicio recomendado por semana es de 150 minutos de ejercicios suaves o 75 minutos de ejercicio vigoroso por semana.

Por lo tanto, cuando se calcula por semana, esto sería un promedio de 20 minutos de ejercicio por día.

Andar en bicicleta, caminar, hacer jardinería y aeróbicos acuáticos son ejemplos prácticos de ejercicios leves o moderados que podrían aumentar el HDL. Sin embargo, el baile aeróbico, el trote y el salto de cuerda son ejemplos de ejercicios vigorosos que, cuando se combinan con la dieta y la pérdida de peso, conducen a una disminución del LDL.

This should be reversed, it should be a decrease in bad cholesterol and an increase in good cholesterol.

Basically, exercise boosts the  HDL and lower triglycerides. Under normal conditions, Aerobic exercises do not reduce LDL. However, when combined with dietary changes and well-monitored weight loss the combined effect could lower LDL.

Under the standard conditions, the recommended exercise per week is 150 minutes of mild exercises or 75 minutes of vigorous exercise per week.

Therefore, when calculated per week this would be an average of  20 minutes of exercise per day.

Biking, walking, Gardening, and water aerobic are practical examples of mild or moderate exercises that could boost HDL. However, Aerobic dancing, jogging, and rope jumping are examples of vigorous exercises which when combined with dieting and weight losses leads to a lowering of LDL.
