"Physiological responses" to training typically signify the body's adaptation to increased physical demands. These responses include improvements in cardiovascular efficiency, muscle strength, and endurance. Following a training regimen, athletes may experience changes such as lower heart rates at rest, enhanced oxygen uptake, and increased muscle glycogen storage. Such adaptations indicate that the body is becoming more efficient and capable of handling greater physical stress, which is crucial for improving overall performance. Monitoring these responses helps athletes and trainers tailor programs accordingly to maximize benefits and mitigate injury risks.
