耐力 means stamina or endurance. However, depending on the context, it can also mean patience or tolerance.

耐力 is the first part of titles like “endurance swimming.”

The first character means “to tolerate” or “to endure.”

The second character is “power.”

Together, you could say this word means “the power to endure.”

耐久力 means stamina or endurance in Japanese Kanji.

体力 means “physical strength” or “physical power.”

The first character was first simplified in Japan. Later, that simplified version became the standard in mainland China. Just in case you want this version, it is offered here. I suggest it if your audience is Japanese. Most Chinese know the older traditional version, which looks like 體力.

体力 can also be defined: stamina; endurance; physical strength; resilience; resistance to disease; clout; stability.
