I think it’s the Thyroid that regulates metabolism. Lastly, metabolism is the process of converting food to energy therefore it effects energy.
        
                    
             
        
        
        
During low exercise intensity levels you would still be able to sing. Correct answer: A Low-intensity exercise is exercise that gets you to about 40 to 50 percent of your MHR. Examples include a casual walk, a stretch session, a beginners' yoga class or tai chi... Low-intensity exercises can easily become moderate-intensity exercises by upping your pace. However while performing  moderate activity you can talk, but you can't sing.
