max is the fastest tempo where one can use oxygen
during  exercise.  Training  at  any  intensity  above  ~
60%  of  VO2max  is  likely  to  improve  maximal
oxygen uptake in healthy adults. While the lack of a
positive  effects  of  increasing  training  intensity  on
the  increase  in  VO2max  suggests  minimum
additional  benefit  to  higher  intensity  training,  it  is
important to highlight the fact that higher intensities
of training induced adaptations following the bottom
lower  training  session  doses  and  total  training
volumes [ XI].
To  improve  the  VO2  max  program,  training
should  be  done  carefully,  systematically,  regularly
and always on the rise, following the principles and
methods of accurate practice in order to achieve the
expected goals. Thus an alternative training that can
be used and  applied in  improving VO2 max is the
Running  ABC  practice.  ABC  Running  Exercise  is
one  of  the  basic  exercises  that  should  be  done  by
athletic athletes because it  covers all  leg exercises.
Running  ABC  is  divided  into  agility,  balance,  co-
ordinate run.  ABC  Running  Exercise  is  used  to
improve  endurance  in football  athletes  because  the
ABC  Running  exercise  has  a  very  high  intensity.
This is  based  on the  work of stamina at  anaerobic
levels of high intensity, so that the supply or oxygen
intake is not sufficient to provide the work required
by the  muscles,  due  to  insufficient  oxygen  supply,
anaerobic  work  will  always  result  in  oxygen-debt
owed.  Aerobic  capacity  is  especially  important  in
the  stages  of  recovery. It  represents  the  ability  to
perform  work  over  a  longer  period  of  time  in
conditions of aerobic metabolism. [III]
Based on the observation in SMA Negeri 2 Lais,
that there are still many findings of some students,
that they have less body resistance, this is seen from
the ease of students experiencing fatigue and lack of
ability students play football within 2 x 45 minutes.
Based  on  the  background  of  the  above  problems
researchers interested in conducting research on the
issue with the title “The influence of ABC Running
exercise  tehadap  increasing  VO2  max  in  students
ekstrakulikuler football in SMA Negeri 2 Lais“.
Increasing the VO2 Max training program should
be  done  carefully,  systematically,  regularly  and
always  on  the  rise,  following  the  principles  and
methods of accurate practice in order to achieve the
expected  goals.  Thus an alternative  training  that  is
used and applied in increasing VO2 Max is circuit
training. Running ABC is a run in it combined with
Agility Balance Coordination, which serves to train
one's  agility,  balance,  and  coordination.  This
exercise is an exercise that unites the agility, balance
and  coordination  of  a  person  in  one  armed
movement.  The  emphasis  of  this  exercise  is  its
systematically  polarized  and  systematically
movement  from  easy  to  difficult  movements,  from
slow to fast movements.
Within  the  realm  of  endurance  exercise,  most
attention has been focused on exercise limitation as
a manifestation of energy dependence, the ceiling of
performance  capacity  being  considered  linked  to
depletion  of  substrate  (i.e.,  glycogen) and/or  the
limits  of  oxygen  delivery.  Compared  with  other
candidate determinants, the latter is readily assessed
by  a  direct  “yardstick”  (measurement  of  maximal
oxygen  uptake  [VO2max]),  the  greatest  rate  of
oxygen  utilization  recorded  during  a  progressive
exercise test. VO2max is closely linked to endurance
performance  in  both  children  and  adults,  and
increased values accompany athletic training; hence,
it is not illogical to conclude, as evident in standard
texts, that “peak VO2 limits the capacity to perform
aerobic exercise [ I ].
2 METHODS
2.1 Types of Research
Research  to  obtain  optimal  results  should  use
appropriate research methods. This type of research
is  quantitative  research  because  the  data  will  be
obtained  in  the  form  of  numbers  that  will  be
analyzed by statistical calculation (Sugiyono, 2015:
13).
2.2 Research Design
The method used in this research is the experimental
method  in  the  form  of  Quasi  Eksperiment. With
consideration  of  the  difficulty  of  controlling  all
variables that affect the variable being studied, then
the researcher chose Quasi Eksperimen. The design
of  this  study  is  pretest-posttest. Draw  the  research
design as follows:
Pretest Treatment Posttest
Figure 1: Research Design (Sugiyono, 2015:42).
In this research the test is done twice as much as
pretest  (before)  and  postest  (after)  treatment
(treatment).  The  difference  between  pretest  and
