Oxygen metabolism analysis under hypotensive risk in maximal anaerobic stress

In response to the surge in novice weightlifters lacking prior athletic conditioning, this research addresses the potential risk of inadequate aerobic capacity during maximal force attempts, coupled with insufficient metabolic adaptations for energy production and utilization during heavy lifts. The primary question is whether a 4-week periodized training program, integrating an endurance component weekly, can enhance athletes' aerobic capacity, thereby improving lift efficiency and safety against hypoxic conditions during bracing. The methodology involves initial profiling and standardized tests for power output and lifting capacity. During testing, athletes perform deadlift repetitions at 80% of their maximum, connected to a VO2 Max equipment for continuous oxygen and carbon dioxide measurement during inhalation. Lactate levels are measured before, during, and after the test to analyze fatigue response and lactate threshold. Additionally, oxygen saturation in blood is monitored as a control, assessing energy utilization and potential hypoxic conditions. Expected results anticipate improved lifting capacity, reflected in reps, maximal weight, RPE (Rate of Perceived Exertion), or enhanced power efficiency at the end of the 4-week training cycle. If proven, the study suggests that occurrences of hypotensive events in weightlifting, particularly in sports requiring lifts exceeding the athlete's body weight multiple times, may be attributed to inadequate preparation for the exertional conditions. Consequently, the research advises incorporating hybrid conditioning to lift heavier and safer, providing valuable insights for the broader sports community.
