Aim: To design a set of specific tests, establish standardized levels and establish benchmarks for measuring performance endurance of some basic skills for junior table tennis players using ball canon. Methods: The researchers used descriptive (survey) approach. Research community included all junior table tennis players who were registered in the Egyptian Table Tennis Federation during 2016-2017 (n=352). Participants (n=112) were distributed to pilot sample group of (16) players (14.3%) and main sample group of (96) players (85.7%). Results: The researchers designed a set of validated tests for measuring performance endurance of some basic skills for table tennis junior players using the ball canon. The set of tests enjoy high validity and reliability and this indicates it objectivity. The set of tests diagnose weaknesses and strengths of junior table tennis players less than 18 years concerning performance endurance of some basic skills on various places of the table. The set of tests cover the most frequently used basic skills in various game situations. Criteria of tests (velocity – spin – direction – place) can be used in measuring all individual and complex basic skills according to various game situations. The set of tests help categorizing players and improving their abilities according to fast improvements in table tennis. The researchers established the standard levels of performance endurance tests for junior table tennis players less than 18 years. The researchers established the benchmarks of performance endurance tests for junior table tennis players less than 18 years. The researchers established the levels of performance endurance for junior table tennis players less than 18 years using these tests.
