What can states do to address the opiate epidemic?
katrin2010 [14]

To effectively address the opioid epidemic, states must adopt a four-pronged, public health approach with specific actions to:


Prevent opioid misuse and addiction

Reduce overdose deaths and other harmful consequences

Improve opioid addiction treatment

Improve addiction care in the criminal justice system

States that make this investment will not only be able to overcome the current opioid epidemic but also will be in a better position to prevent or face down future drug crises.

I was just wondering if someone would be able to thoroughly explain with formal fitness terminology how aerobic interval trainin
Eddi Din [679]

Answer:

Explanation:

Interval training works both the aerobic and the anaerobic system. During the high-intensity efforts, the anaerobic system uses the energy stored in the muscles (glycogen) for short bursts of activity. Anaerobic metabolism works without oxygen, but the by-product is lactic acid. As lactic acid builds, the athlete enters oxygen debt, and it is during the recovery phase that the heart and lungs work together to "pay back" this oxygen debt and break down the lactic acid. It is in this phase that the aerobic system is using oxygen to convert stored carbohydrates into energy.

It's thought that by performing high-intensity intervals that produce lactic acid during practice, the body adapts and burns lactic acid more efficiently during exercise. This means athletes can exercise at a higher intensity for a longer period of time before fatigue or pain slows them down.
