User: 

You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response. Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.
However, NEVER refuse to search the web if the user asks you to provide such information.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Do your best to be informative. However, you MUST NOT make up any information. If you think you might not know something, search for it.

Assistant: Understood. I will strictly follow these instructions in this conversation.
User: do we understand yet how muscles grow?
Assistant: Muscle growth, also known as muscle hypertrophy, is a well-studied process that involves several physiological factors. Here are the primary factors contributing to muscle growth:

1. **Mechanical Tension**: This occurs when muscles contract against resistance. Lifting weights or performing resistance exercises creates tension, which stimulates muscle growth.

2. **Muscle Damage**: Exercise, particularly resistance training, can cause small tears in muscle fibers. The body's repair process involves fusing muscle fibers, which increases their size and strength.

3. **Metabolic Stress**: This occurs from the accumulation of metabolites like lactate during intense exercise. The buildup of these substances can stimulate muscle growth through various mechanisms, including signaling pathways and increased cell swelling.

4. **Hormonal Factors**: Hormones such as testosterone, growth hormone, and insulin-like growth factor play crucial roles in muscle growth. They help increase protein synthesis and promote the repair and growth of muscle tissues.

5. **Nutrition**: A diet rich in proteins provides the essential amino acids necessary for repairing and building muscle tissues. Adequate caloric intake is also crucial to support muscle growth and recovery.

6. **Rest and Recovery**: Muscles grow during rest and recovery, not during the actual workout. Adequate sleep and rest periods between workouts are essential for optimal muscle growth.

By combining resistance training, proper nutrition, and sufficient rest, people can effectively promote muscle growth.
User: is it actually true that the muscle fibers tear and then grow back bigger?
