Eight (n = 8) healthy men were randomly separated into two experimental groups: A) the order from multi- to single-joint exercises (MJ-SJ) and B) the order from single- to multijoint exercises (SJ-MJ). For all exercises in both orders, the subjects were submitted to 3 sets of 10 repetitions, with rest intervals of 2 minutes between sets and 3 minutes between exercises. Blood samples were collected at rest and 0, 15, 30, 60 and 120 min after the end of the exercise session. In thyroid-stimulating hormone (TSH), differences between groups (MJ-SJ < SJ-MJ) were observed within 15 minutes after the session. In 3,5,3’-triiodothyronine (T3), differences between groups were observed between 30 (MJ-SJ > SJ-MJ) and 120 minutes (MJ-SJ < SJ-MJ) after the session. In 3,5,3’,5’-tetraiodothyronine (T4), differences between groups (MJ-SJ > SJ-MJ) were observed within 15 minutes after the RT session. The order of RT exercises significantly changes the hormonal responses of TSH, T3 and T4. In addition, the exercise order should be chosen according to the individual’s objectives.
