Excitation Levels Reflect Strength Potential

Measurements from surface electromyography (SEMG) indicate that higher electrical activity levels suggest increased muscle excitation, potentially leading to enhanced strength and hypertrophy outcomes, although this remains unproven. Additionally, intramuscular pressure serves as an indicator of muscular activity; increased pressure correlates with greater force production. Data reveals that the use of lifting belts does not significantly alter trunk muscle activity, suggesting that they do not hinder muscle function or fitness adaptations during weightlifting. Furthermore, research indicates that regular use of lifting belts is associated with improvements in muscular strength and endurance over time. Lastly, the prevalence of low back pain is significant, affecting nearly 85% of the general population and 61% of athletes, highlighting a common risk associated with physical activity.
