Anaerobic alactic muscle power endurance of high performance basketball
players during competitive period
The alactic anaerobic pathway is when the body is
working anaerobically but without the production of
lactic acid. This pathway depends on the fuel stored in
the muscle which lasts for approximately 4-15 seconds
at maximum effort. There is a problematic issue: what
is the anaerobic alactic endurance of high performance
basketball palyers and what it depends on. The aim
of our recent study is to assess anaerobic alactic
endurance of high performance basketball players
during competitive period.
It has been studied players (n=12) of Lithuanian
national basketball league aged (mean ± standard
deviation) 20,1 ± 1,8 years, with body mass 94,2 ±
10,3 kg, training experience 9 ± 1,5 years. They have
trained 6 times for 2 hours during the week and played
two matches. It has also been studied in basketball
untrained but physically active group of students
(n=15) aged 21,3 ± 0,9 year, with body mass 77,8 ±
6,1 kg.
10 second maximal ergometer sprint test was used
for setting anaerobic alactic power and endurance.
With use of Monark Ergomedic 894 Ea ergometer,
work gear has been selected for resistance to the
body mass: pedaling 70 rep/min on 4 watts of body
mass. After 15 min warm up, including a practice
start requiring the athlete to accelerate, subjects had to
work to maximum power and to maintain it for 10 s.
Work output (W) was recorded. The anaerobic alactic
endurance of high performance basketball players was

Summary
the maximum capacity of work time. During the test,
the average power value 1364,0 ± 168 was reached
between 2 and 3 seconds and a peak power output
between 5 and 6 seconds. In the group of physically
active students work was distinguished by figures of
such trends: the average power (832,4 W) achieved
between 4-5 s, peak power in 6 s. Power loss reflects
our investigated endurance of anaerobic alactic power.
Basketball team players average endurance was 6,00
± 1,1 s. This ratio of physically active students was
6.07 ± 1.2 s. A statistically significant difference was
not found (p>0.05). Endurance characteristics of both
groups is the dispersion area of 4 to 8 seconds, and
the players dispersion around the mean is the average
V=18,3 perc.
Our research shows that high performance
basketball player have the same anaerobic alactic
endurance as physically active students. Basketball
training and competitions have a great impact on
anaerobic alactic muscle power. Our previous studies
showed that basketball players have a high rate of
endurance of intermittent work.
It may be theoretically assumed that basketball
performance does not have direct effect on work
endurance of ATP-PC system. The game gets a big
power in a short work, the ability to quickly recover
and repeat the action at high power again.
Keywords: anaerobic alactic reactions, endurance,
basketball player.
