Ok Elve I don't know if you're referring to direct literal manga RAW translations or not, but you don't have to be suck a stickler. Senju and Uzumaki's do have strong stamina, which is evidenced by Kushina and Naruto both surviving Kurama's extraction (yes I know Naruto was unconscious, but he was still alive), Hashirama and Naruto's excessive chakra reserves (yes both Asura's transmigrants) and more. Stamina is physical endurance or how long they can last performing physical activity. This is linked directly to physical energy. Also vitality is defined as "physical or mental vigour or energy" or "the power to continue in existence, live or grow". So again it is another way of saying physical energy.
