• Hypothesis: The study hypothesized that leucine-enriched EAAs could enhance muscle protein synthesis more significantly than EAAs alone after resistance exercise.

Overview & Findings: The findings confirmed the hypothesis, revealing that leucine-enriched EAAs significantly increase muscle protein synthesis rates post-exercise compared to standard EAA mixes. This effect was attributed to leucine's ability to activate the mTOR pathway, which is critical for muscle building. This study emphasizes the importance of leucine concentration in EAA supplements for athletes and individuals looking to maximize muscle recovery and growth.

• Hypothesis: The research aimed to determine if EAA supplementation could improve muscle recovery and growth when combined with resistance training.
• Overview & Findings: The study found that participants who took EAAs showed better recovery and increased muscle size compared to those who did not. The EAAs appeared to reduce muscle protein breakdown and enhance protein synthesis, which contributed to more effective muscle repair and growth post-exercise.

• Hypothesis: This study hypothesized that there is an optimal amount of EAAs necessary for maintaining muscle mass, particularly in the aging population.

Overview & Findings: Researchers concluded that an increased intake of EAAs can significantly help maintain muscle mass, especially as natural muscle degradation occurs with age. The study provides crucial dosage guidelines that can help older adults preserve muscle function and overall physical health.

• Hypothesis: The study aimed to evaluate how EAAs affect muscle protein synthesis after exercise.
• Overview & Findings: The results indicated a robust increase in muscle protein synthesis following intake of EAAs post-exercise, suggesting that immediate supplementation can significantly hasten recovery times and enhance the body's ability to repair and build muscle tissue effectively.

• Reference: Ra et al. (2019). Link to study
• Hypothesis: The study investigated whether EAA supplementation could mitigate muscle damage and inflammation resulting from strenuous exercise.

Overview & Findings: Findings showed that EAAs help reduce markers of muscle damage and inflammation, supporting faster recovery. This suggests that EAAs can be particularly beneficial for athletes engaged in high-intensity training by minimizing downtime and enhancing readiness for subsequent training sessions.

• Hypothesis: EAAs taken before exercise can sustain muscle force and reduce fatigue.
• Findings: Confirmed that pre-exercise EAA supplementation helped maintain force and reduced fatigue, underlining the role of EAAs in enhancing performance and recovery during strenuous activities.

• Hypothesis: EAAs could produce a greater muscle response compared to hormones like testosterone or HGH.
• Findings: Found that EAAs generated more than four times the peak muscle response compared to hormone injections.
