Cardioprotective Effect of a Helcometer Bar with Expander System

Abstract

The study was carried out on 5 healthy volunteers with a mean age of 30.4±9.30 years, mean height of 180±0.02 cm, mean weight of 82.2±4.44 kg, and mean wingspan 180.6±3.78 cm. Each subject performed a set of pull-ups on the lat machine using the regular bar and the bar with an expander system (innovative system), as well as a barbell bench press set with and without added elastic resistance. Each set comprised 15 repetitions, and the total resistance was below 50% of 1 RM, in case of using the same gravitational resistance. A Beurer pulse oximeter was used to determine the heart rate and oxygen saturation during resting conditions, upon completion of the exercise and during the post-effort recovery period. The maximum heart rate recorded during post-effort recovery was most of the times lower when using added elastic resistance, and the same happened with heart rates recorded upon completion of the exercise sets. The interpretation of variations in oxygen saturation levels is indicative of an enhanced cardioprotection in case of using the lat machine bar with an expander system. This cardioprotective effect can be useful in the prophylaxis and treatment of certain heart diseases.
