BACKGROUND: Studies have shown the benefits of exercise, but few investigate the effects of resistance training methods on glucose and blood pressure behavior. The aim of the study was to analyze glycemic and blood pressure responses after different resistance exercise methods.
METHODS: Eighteen young healthy men (23±1 years; 24±0.5 kg/m2) with experience on resistance training performed the methods: drop set (DS), rest pause (RP) and three sets of fifteen repetitions (3×15) at bench press (BP) and squat (Sq) exercises, in random order and separate days. Blood pressure and heart rate were monitored at rest and during 60 minutes after exercise (15’, 30’, 45’, 60’). Blood glucose was analyzed at rest (fasted) and immediately after the exercises.
RESULTS: The area under the curve of systolic blood pressure (SBP) in the DS method showed a greater reduction compared to the RP method (DS: -479±106 vs. RP: -64±93 vs. 3×15: -249±91 mmHg·60 min; P<0.05) after BP exercise performance. Besides, DS method reduced SBP after BP exercise all time (15’ to 60’) when compared to rest (P<0.05). Diastolic blood pressure (DBP) reduced in DS method all time (15’ to 60’) after Sq exercise and in 3×15 method after BP exercises when compared to rest (P<0.05). Blood glucose reduced immediately after exercise in DS (pre: 94.2±3.3 vs. post: 82.7±2.2 mg/dL; P<0.05) and RP (pre: 94.1±2.7 vs. post: 85.9±2.2 mg/dL; P<0.05) methods.
CONCLUSIONS: In conclusion, the DS method promotes a longer and greater reduction in SBP when compared to the RP method on BP. In addition, we found that post-exercise DBP hypotension for 60’ after performing the DS method on Sq and after performing the 3×15 method on BP. The glycaemia reduced immediately after the DS method and the RP method performed on BP.
