Isometric Exercise
Conditions
Brief summary
: Isometric handgrip (IHG) is a classic sympatho- excitatory stimulus often used in autonomic testing. Aims: The aims of this study were to evaluate the acute cardiovascular response and recovery following isometric handgrip (HG) exercise-induced fatigue on healthy adults. Secondary, to examine correlations between isometric handgrip strength and both systolic (SBP) and diastolic (DPB) blood pressure' Methods: Study was a repeated measure single group design. Thirty-five healthy volunteers, 20 females and 15 males, age (36.16 + 6.11years) were enrolled in the study. Study was at out Clinic of October 6 University. Demographic data were collected at beginning of session. Subjects were then assessed for baseline (BL) blood pressure (BP). Maximal isometric voluntary contraction (MIVC) for each subject was the average of two-5 seconds MIVCs of dominant hand using a hand-held dynamometer separated by 1 minute of rest. Subjects were allowed 5 minutes rest, then performed fatigue protocol (FP) using the hand-held dynamometer with their dominant hand at 50% MIVC for 3 minutes as a One minute of rest was given following FP then subjects were reassessed for BP and MIVC of dominant hand respectively (Immediate reassessment). Further, BP was reassessed for 3 times at 5 minutes interval between measures.
