Cardio-Vascular and Respiratory Responses to Valsalva Maneuver, Isometric Hand Grip Exercise and Harvard Step Test and Recovery in Healthy Individuals

To assess the responses of Cardiovascular and respiratory system to Valsalva maneuver, Isometric handgrip exercise, and isotonic Harvard step test in healthy individuals.

Randomized design used in this study to find out the effect of 3 different physical stressors on healthy individual.

OPD of KLES College of Physiotherapy Hubli.

300 Healthy individuals randomly allotted into 3group (A, B, C) with homogeneous gender distribution and of age group 16 year to 30 years.

Group A underwent Valsalva maneuvers, Group B was exposed to Isometric exercise sustained handgrip, and Group C performed Isotonic exercise Harvard step test.

Inter and Intra group analysis for significance was done taking pre and post Exercise value and ANOVA and found the following. Intra group within A (A1, A2, A3) none of the value found significant, also the values of B group does not show any significance with present data. In-group C Systolic Blood pressure(BP), Rate pressure product(RPP) and Double product (DoP) shown great significance may be attributed to age and stress level. Stress level may be more appropriate as it effecting Systolic BP and in turn RPP and DoP. Inter group analysis through ANOVA shows other then Pulse rate of A1, B1, C1 nothing found significant.

The greater stress levels have significant changes in parameter even in normal young individual. Few individual have shown poor cardio-vascular responses during exercise and at recovery period. Hence risk for sub clinical heart aliment cannot be overruled just by looking the baseline parameter at rest. Sedentary individual were slow to recover then active individual.
