Abstract

The aim of this study was to develop a new basketball-specific field test (BSFT) that
determines the maximal oxygen uptake indirectly and to determine the reliability and
validity of the test for measuring aerobic power.

An aerobic endurance-based test totalling 1.5 miles on a basketball court including side
steps and running was designed to be completed as quickly as possible. 15-year-old, male
basketball players’ maximal oxygen uptake (VO2max) levels measured directly as the gold
standard laboratory test.

Laboratory test results showed a significant negative correlation between the VO2max level
and the duration of the BSFT (r = -0.705, p = 0.015). Regression analysis through the BSFT
proved moderate validity (R2 = 0.390), and the following regression formula was then
developed to estimate the VO2max level: 122.617–5.461×(BSFT duration). The reliability
was evaluated by the test-retest method; there was no difference between the duration of
the BSFT (p > 0.05) repeated at intervals, and this test showed high reliability (%CV:8.81
and ICC:0.90).

The BSFT, which proved to be reliable and valid for measuring aerobic power indirectly,
may be considered to help coaches and athletes by means of its properties that do not
require expensive equipment and specialist staff and ensure easy and practical application
by using simple basketball-specific movements on basketball courts.
