Abstract

Through the application of scientific
research methodologies—including literature
review, expert interviews and seminars, and
statistical analysis—we have selected 20 exercises
and 04 assessment tests for evaluating the power
(speed-strength) of male tennis players in the 12-14
age group from Ninh Binh province. The selected
tests have demonstrated sufficient reliability
and informative value for this specific athlete
population.
