The study examined neuromuscular fatigue responses in 32 participants during incremental cycling exercises, divided into endurance-trained (triathletes), strength-trained (bodybuilders), and recreationally active control groups.
Significant differences in muscle response metrics (median and mean power frequency) were found between endurance and strength groups, indicating varied fatigue profiles.
Endurance athletes showed lower muscle activation than strength trainers and experienced lower perceived exertion at higher workloads, suggesting that training background influences fatigue during cycling.
The study aimed to assess the immediate effects of progressive submaximal cycling on cardiorespiratory and metabolic variables in endurance-trained athletes (like triathletes) and strength-trained athletes (like bodybuilders), along with a control group of recreationally active students.
A total of 32 participants were split into three groups, and their heart rate, oxygen uptake, and other metabolic factors were measured during incremental cycling workloads up to 200 W.
The results showed that while cardiorespiratory responses were similar between endurance and strength athletes, there were significant metabolic differences, particularly in respiratory exchange ratio and blood lactate levels when compared to the control group, suggesting that endurance athletes may benefit from combining strength training for better performance.
