The effect of training according to the target intensity index in developing strength among weightlifters

Abstract

Weightlifting is considered one of the activities in which strength is shown at its best, and researchers and coaches are still working hard to find the best ways to achieve optimal performance and achieve excellence. This research aims to develop specific exercises that focus in their content on unique diversity, in harmony with the type of activity and movement components, in addition to focusing on the appropriate timings for implementing these exercises. The bench press exercise was chosen for body strength players, and a sample of players (8 players) underwent pre- and post-tests. The experimental group underwent a special set of exercises for a month and a half, at a rate of three training sessions per week, for a total of 18 training units. The researcher conducted a field test to measure the actual performance strength of each player, while calculating the percentage achieved in relation to the mass of each player. A special examination was also carried out using muscle activity recording technology, based on the maximum achievement, and adopting the target training zone (TTZ) indicator, with the calculation of muscle work percentages (under, above, inside) in this zone. The results showed that the experimental group was superior in improving performance, despite the progress observed in both groups. The results also showed a clear change in the percentage of work within the target level, in favor of the experimental group.
