A-Maximum cardiovascular variables during sustained handgrip at 30% of maximum voluntary contraction, B-Sitting (resting) cardiovascular variables
SD: Standard Deviation, SBP: Systolic Blood Pressure, DBP: Diastolic Blood Pressure, MAP: Mean Arterial Pressure, PP: Pulse Pressure, RPP: Rate Pressure Product, bpm: beats per minute, SH: Sustained Handgrip. There was a statistical significant difference between the sitting and maximum cardiovascular variables during sustained handgrip; SBP, DBP, MAP, PR and RPP (t=19.54, p<0.001; t=16.58, p<0.001; t=18.54, p<0.001; t=22.04, p<0.001, t=23.17, p<0.001 respectively). No significant difference in the PP at rest (sitting) and during the sustained handgrip (t=1.44, p=0.152).
