Blood flow restriction training (BFRT) can increase strength and hypertrophy. Comparing mechanisms of strength and hypertrophy during high-load training versus BFRT and low-load training guides clinicians to program effective rehabilitation and training programs. This course is intended for physical and occupational therapy practitioners, and strength and conditioning specialists.

Chapters & learning objectives
1. Muscle Anatomy and Function
Understanding the importance of muscle for movement, metabolism, and resilience is important in order to promote lifelong resistance training. Lifelong resistance training allows maintenance and even growth of more muscle mass compared to losing muscle over time (sarcopenia).
2. Low-, Moderate-, and High-Load Training
The differences between low-, moderate-, and high-load training can be substantial. It is important to understand how programing to build muscle is similar but different in all three cases.
3. Fiber Type Recruitment and Cellular Swelling
By allowing a small amount of blood to the limb and restricting venous return, blood begins to pool in the extremity. This pooling builds up and eventually pushes fluid into the muscle cell, which stimulates muscle protein synthesis. Pooling also allows the buildup of metabolites in the occlused limb, which results in early fatigue of type I muscle fibers.
4. Autocrine and Paracrine Response
Understanding the cell's response to resistance exercise helps us understand the mechanisms and benefits of strength training. The body and brain also respond with local and systemic hormone release to help recover from a training episode.
