Answer:En principio, el ejercicio cardiovascular es el que más consumo calórico produce y cuanto más ejercicio, mayor consumo y mayor pérdida de grasa. Esto es así hasta cierto punto. Existe una situación a partir de la cuál nuestro organismo entra en una situación de extrema demanda y se activa un mecanismo de defensa que protege a la grasa. En estos casos, se empieza a catabolizar la masa muscular, baja el ritmo metabólico y disminuye nuestro rendimiento. Se entra en una espiral de fracaso, y cuanto más entrenemos, menos resultados obtendremos.
Con un volumen semanal de entre 4 y 6 horas de trabajo cardiovascular a la semana tenemos suficiente para conseguir el objetivo de perder grasa. Si deseas mejorar, a partir de este punto no aumentes los aeróbicos, mucho mejor incluye un programa de entrenamiento de la fuerza. Está comprobado que los resultados del trabajo combinado cardiovascular/fuerza son siempre más positivos.

Answer:
A. epinephrine
Explanation:
Bronchial constriction usually involves the tightening of the smooth muscles which surrounds the tube-like bronchial airways. This occurs via extra mucus production, spasming of smooth muscles, or swelling/inflammation of layers within bronchi or bronchioles. Bronchial constriction typically results in symptoms of wheezing, coughing and shortness of breath.
This can be treated via the use of the hormone epinephrine, a bronchiodilator. For some cases like asthma, epinephrine in small aerosolized (inhaled) doses can lead to the <em>temporary</em> relief of symptoms. Epinephrine acts by making bronchial tubes wider to allow the passage of air.
In the body, smooth muscle cells in the veins, arteries and heart are under the control of epinephrine receptors called β2 receptors. Epinephrine binding to the receptor triggers a cell signalling cascade that activates β2 receptors to dilate smooth muscle in the lungs.
Here's how-
- Calcium is essential to mediating muscle cell signalling and thus contraction
- in the lungs, epinepherine-β2 receptor binding leads to enzyme activation (adenylyl cyclase)
- conversion of the energy molecule ATP to the secondary messenger molecule cyclic AMP.
- cAMP inhibits the activity of the enzyme <em>myosin light chain kinase </em>(MLCK) in smooth muscle
- ∴ the enzyme remains inactive and the muscles relax
<em>Summary:</em><em> epinephrine → muscle relaxation →</em><em> bronchial dilation (reduced diameter) </em><em>→ decreased respiratory distress → easier breathing.</em>
