in higher swimming speeds by adjusting the
coordination of the right limb movements with
shorter or less sliding glucose or arm action with
overlapping legs results in a higher overlap index.
(Marek Strzala, 2013)
Motion coordination is an important part of
improving motion performance, motion performance
is much needed for sports students, because 60% of
the sport‘s curriculum structure is practice.
3.2.4 Abdominal muscles strength
Strength of abdominal muscles of prospective
students of sports track SBMPTN and Mandiri in
2015-2017 in very well criteria from 811 to 26, and
mandiri track rose 10 to 19, muscle strength should
be in line with the maturity of sex hormones in men,
(Sugiyanto, 1997) which closely occurs between
forces with the release of hormones in men,
testosterone hormone has a positive effect on the
increase of muscle strength, so it should be in
adolescent period of increased abdominal muscle
strength in line with the development and maturity
of men’s secondary sex. This development can be
utilized for exercise (Sumiaki Maeo, 2013)
abdoment bracing proved to be one of the most
effective exercise methods for abdominal muscles
although compared to dynamic exercises involving
flexion / abdominal extension movements.
3.2.5 Strength of Arm muscles
The muscle strength of the prospective sport
student‘s arms of the SBMPTN and Mandiri tracks
in 2015-2017 has very good criteria, rising from 66
to 68, and Mandiri hitting 50 to 25, the results of this
test have been written (Sugiyanto, 1997) that men
experience rapid, physical changes, strength.
Adaptation exercises have influence with
practice closer to 1 RM person.
Alternatively, the
increase in muscle size appears to be driven more by
higher exercise volume, at least to a certain
threshold, (Schoenfeld, 2016) strength training
should have started from the initial adolescent
period, exercises with 1 RM principle and intesitas
can increase muscle mass.
Combining the loading
strategy may have a synergistic effect on strength
and hypertrophics (Schoenfeld, 2016).
Drop set
resistance training initially performed with higher
load increases muscle activity and intramuscular
hypoxia during subsequent exercise with 75% 1RM
burden among trained individuals (Masahiro Goto,
2016).
3.2.6 Cardiovascular endurance
Cardiovascular endurance of students of SBMPTN
and Mandiri sports track in 2015-2016 criteria is
very good, decrease from 6 to 1, and stable 1 for
Mandiri track, this result has not yet shown any
exercises done to improve cardiovascular endurance
because (Sugiyanto, 1997) the strengthening
exercise for better cardiovascular resistance should
begin earlier, an increase in adolescence is higher
than adults. The results of the study (Stöggl, 2017)
among youth in accordance with the study of adults
who showed the importance of upper body strength
and endurance that support the performance of
motion. Low cardiovascular endurance can be due to
poor physical activity and not yet know the right
exercise, while reviewing many studies that can be
used as a reference to improve cardiovascular
endurance exercise, Hypoxic training methods that
utilize height training, both in nature / terrestrial and
artificial, has been established as an effective means
of improving oxygen transport, RBC volume, and
VO2max, given a sufficiently high dose of
“altitude” and duration, (Jacob A. Sinex, 2015)
4 CONCLUSIONS
The best profile of tested prospective students is the
SBMPTN line 2015, but when compared to the
benchmark references, the average test result is in
the medium category. So it takes proper exercise to
improve the physical condition, so that with good
physical condition can affect the performance of
motion.
