The effect of flexible bar and isolation cube exercises on developing the types of muscle strength, upper limb motor balance, mechanical launch variables, and digital level of male shot put throwers

Abstract

The aim of the research was to identify the effect of flexible bar and isolation cube training in developing types of muscle strength and motor balance of the upper limb. The researchers used the experimental method by designing two equivalent experimental groups. The research sample was the weight throwers for the 2024 sports season who won the first eight places in the Iraqi Clubs Championship out of 12 players participating in the competition held at the College of Physical Education and Sports Sciences Stadium / University of Sulaymaniyah. The types of strength (maximum, explosive, characterized by speed) and motor balance of the upper limbs were measured and the achievement test was photographed to extract mechanical launch variables through photography. The researchers concluded that the special training for types of muscle strength of the upper limb with the flexible bar and isolation cube used by the experimental group and the regular weight training used by the control group led to the development of types of muscle strength (maximum, characterized by speed, explosive). The researchers also recommend the use of unilateral training (with one limb) with the isolation cube and flexible bar.
