Treinador vs. técnico
In Portuguese, treinador and técnico are often used interchangeably to mean coach, especially in the context of football (soccer). However, there is a nuance in their roots: treinador implies someone who conducts physical training and drills, while técnico implies someone who manages strategy, tactics, and technical decisions.
Treinador
A2Derived from the verb treinar (to train), treinador focuses on the aspect of teaching skills, physical conditioning, and guiding practice sessions. It is the preferred term for individual sports, personal trainers in a gym, and animal trainers.
O treinador preparou uma série intensa de exercícios físicos.
(The coach prepared an intense series of physical exercises.)

(My swimming coach corrected my posture in the water.)
Técnico
B1Derived from técnica (technique), técnico usually refers to the head coach or manager of a sports team. It emphasizes the strategic role, such as choosing the starting lineup, making substitutions, and defining game tactics rather than just physical exertion.
O técnico mudou a tática do time no intervalo.
(The coach changed the team's tactic at halftime.)

Summary
While you can often use both words for a sports coach, use treinador when focusing on physical preparation, individual instruction, or animal training. Use técnico when referring to the strategic manager or head coach of a team who makes tactical decisions.
