The Positive Effects on Volleyball Receiving Skills When Training with Lighter Balls
Round 1
Reviewer 1 Report
Dear Authors,
Thank you for the opportunity to review the submitted paper “The effects on volleyball receiving skills when practicing with different weight volleyballs”. This study investigated the reception capacity in volleyball after practicing with balls of different weights. The study is interesting and with a lot of applicability in learning and training. Some changes in the text may contribute to a better understanding of the reader. The introduction reviews the literature and leads the reader to the objective of the study, however it becomes lengthy in its current format. The purpose of the study is confused in relation to the results, the writing must be revised, it is necessary to maintain a standard in the terms used, effectiveness and performance are used as synonymous and alternate throughout the text, this must be corrected. The methods are detailed, but it took me a while to understand the experimental design of the study, I suggest a clearer design to help the reader. The study results are interesting, but the presentation format should be improved, I suggest inserting a table to reduce the text and make the text clearer and less "statistical". In the discussion, authors should further explore the practical applications of the study. The conclusion is long and confusing, it is necessary to make it clear and more direct. In general, the text needs a revision in writing, but I believe that with the revision of the cited points and the writing it is interesting for professionals and researchers in the area.
Details
- The title could be more direct, for example, indicating the positive effect of training with lighter balls.
- To correct: “2.5. Data processing”
- Figure 2 should be improved, the statistical results in the figure are not clear. Its aesthetic quality and clarity in description should also improve.

I found the manuscript quite interesting because of the practical application of teaching serve reception. The strong point of the work is the interesting idea to conduct a study. I regret that the authors were not tempted to develop the theoretical part and additional conclusions. There are several drawbacks to the paper which must be improved.
