Reviewer 1 Report
This is an excellent paper that adds significantly to our understanding of pre-competition tactics for combat athletes. I was particularly impressed by the readability and translatability for someone who does not have a background in combat sports. I have no significant issues to note.

Reviewer 2 Report
This is an interesting paper attempting to describe the role of caffeine on the performance of sport activities in young subjects with a mean age of 17.5 years. Four groups were studied. The effect of low dose of caffeine 3mg/kg alone or combined with conditional activity was compared to placebo group that was subjected or not to conditional activity. Different tests were performed to assess the physical response to caffeine; while scores were used to evaluate the impact on the psychology (mood, vitality, feeling, perceived exertion and recovery) of each of the participants.
In addition, males and females were recruited to help identifying any sex-difference in response to caffeine.
Caffeine combined to conditional activity improve the performance in all subjects. However, both physical and psychological responses were greater in males than in females.
The study is seriously conducted, and the results are convincing. I must congratulate the authors for this well performed study.
Here are few pitfalls that need consideration:
- Authors can make effort to decrease abbreviations and rend the paper more agreeable or friendly to read
- Line 168: add the number 4) and 5) to complete the numeration of tests.
- Line 269: delete “very large”, it is repeated twice
