The Effect of Short-Set High-Load and Long-Set Low-Load Isometric Exercises Based on Stress-Strain Isometric Time-Dependent Strength Trial on Weightlifters Performing Resistance Training Periodization

Introduction. Isometric deload resistance training is both short set high load and long set low load, combining the implementation so-called “recovery” or “light” weeks to expose stress load strain energy generation, enabling to isometric load time set curve – indeed controversial and previously uncleared – on undulation, different set configuration and repetition zone working. Objective. Our study aimed to investigate available stress-strain relationship on different set configuration “deload training regimes” in Olympic and professional weightlifters. Materials and methods. Four Olympic and professional weightlifters (1 women and 3 men) were included, mean age: 21.50 ± 7.85 years, height: 1.68 ± 0.03 m, weight: 70.75 ± 13.69 kg, deload resistance training over 3 week and per week 2 days. Results. Isometric modeling deload resistance training periodization was generated, stress load strain energy generation promoting low load vs high load repetition session into light weeks, different set configuration and rest interval. Each isometric resistance exercise session showed dynamic strength increased by undulation sets and repetition zone ranges, isolated isometric load time decreased by training volume change, and endurance localization increased by deload loading working principle on maximize performance. Conclusions. Specific undulation short term periodization properly enhanced maximize performance of weightlifting resistance training athletes, in this case bi-weekly non-linear different set configuration can be supported to optimize stress load strain energy generation.
