A Non Randomized Controlled Study to Evaluate the Effect of Isotonic Handgrip Exercise on Blood Pressure in Normal Weight and Preobese Healthy Adults
Keywords:Isotonic Handgrip Exercise, Normal weight and pre-obese adults.
Background: The adverse health consequences of overweight and obesity in India leads to higher prevalence
of diabetes mellitus and cardiovascular diseases. Also the compliance of people for routine form of exercise
for BP control has not been very encouraging due to time, place etc constrains.
Aim: Therefore we conducted a nonrandomised clinical study to determine the short-term effects of
isotonic handgrip exercise by using smiley balls on blood pressure in healthy normal weight and overweight
adolescents with the objective to find a user friendly exercise which help in reducing blood pressure.
Method: A non randomized clinical study was conducted on 100 young normal-weight and pre-obese adults
(50 Boys and 50 Girls) in the age group of 18–25 years. Isotonic handgrip exercise was performed at the
rate 20 contractions/minute (2 sec contraction/1 sec relaxation) at maximal intensity for 10 minutes using
smiley ball. Pulse rate and blood pressure parameters were tested at baseline and immediately after exercise
in post-exercise recovery period.
Result: Statistically significant reduction was observed in systolic blood pressure(SBP) and mean arterial
pressure (MAP) in both pre-obese boys and girls groups while pulse pressure & mean arterial pressure in
normal weight girls after exercise regime.
Conclusion: We conclude that the exercise regime under consideration can produce some short-term
beneficial effects with respect to blood pressure in especially pre-obese group of adults.
