The effect of different intensity modalities of resistance training on beat-to-beat blood pressure in cardiac patients.
BACKGROUND Resistance training has been introduced in cardiac rehabilitation to give more benefit than traditional training . Haemodynamic evaluation of cardiac patients to resistance training has generally consisted of continuous HR monitoring and discontinuous blood pressure measurements . DESIGN AND METHODS Blood pressure ( BP ) and heart rate ( HR ) responses to resistance training were evaluated using continuous monitoring ( Finapres ) during low ( four sets of 17 repetitions at 40 % of the one-repetition maximum strength [ 1-RM ] ) and high intensity resistance training ( four sets of 10 repetitions at 70 % of 1-RM ) on a leg extension machine in 14 patients who participated in a rehabilitation programme .  Work volume was identical in the low- and high-level resistance training . RESULTS The HR and systolic blood pressure ( SBP ) during low intensity resistance training were always larger than during high intensity ( P<0.001 ) . Peak SBP increased from set 1 to set 3 and 4 during both low and high intensity resistance training ( P<0.05 ) . Peak HR was larger in set 4 ( 95+/-11 bpm ) than in set 1 only during low intensity resistance training ( 91+/-12 bpm ) ( P<0.05 ) . One-minute recovery periods did not allow a return to baseline HR and SBP during both low and high intensity modalities . CONCLUSIONS The SBP and HR responses to resistance training are related to the duration of exercise . Sets with < or = 10 repetitions of high intensity should be preferred to longer sets with low intensity . Pauses between exercise sets should exceed 1 min . Blood pressure should be measured during the last repetitions of the exercise set
