Efek Latihan Longmars Terhadap Kadar Malondialdehida (MDA) Pada Prajurit Kopassus TNI AD = Effect of Longmarch Exercise to Malondialdehida (MDA) Level of Special Forces Soldiers of Indonesian Army.

ABSTRAK

Latar belakang : Latihan fisik telah diketahui memberikan manfaat terhadap
kesehatan. Namun demikian latihan fisik juga berpotensi memberikan dampak
negatif seperti cedera dan terjadinya stres oksidatif. Latihan fisik dengan
intensitas tinggi dan durasi lama dianggap sebagai salah satu faktor yang
menyebabkan terjadinya stres oksidatif. Latihan longmars merupakan salah satu
materi pelatihan Komando yang dilaksanakan oleh peserta pelatihan Komando
pada tahap gunung hutan. Latihan longmars dilaksanakan dengan berjalan kaki
selama 8 hari berturut-turut, kecepatan 5-6 km/jam, membawa beban 35 kg,
melewati medan bervariasi (datar, menanjak dan menurun) dan menempuh jarak
sekitar 500 km. Latihan longmars sebagai salah satu bentuk latihan fisik di
lingkungan militer dengan durasi lama dan intensitas tinggi diduga dapat
menyebabkan terjadinya stres oksidatif. Stres oksidatif dapat diketahui dengan
pemeriksaan Malondialdehida (MDA) yang merupakan penanda stres oksidatif.
Tujuan: mengetahui rerata kadar MDA dan perbedaan rerata kadar MDA peserta
pelatihan Komando sebelum dan setelah melaksanakan latihan Longmars.
Metode: sebanyak 30 subyek penelitian peserta pelatihan Komando dalam
kelompok usia 20-30 tahun yang dipilih secara acak mengikuti penelitian ini.
Subyek penelitian merupakan prajurit terlatih yang telah melaksanakan program
latihan fisik selama 1-4 tahun. Pemeriksaan kadar MDA dilakukan 1 hari
sebelum pelaksanaan latihan Longmars dan segera setelah selesai melaksanakan
latihan Longmars. Hasil: rerata kadar MDA sebelum latihan Longmars adalah
0,729 ± 0,229 nmol/mL, rerata kadar MDA setelah latihan Longmars adalah 0,655
± 0,183 nmol/mL. Tidak terdapat perbedaan bermakna rerata kadar MDA sebelum
dan setelah latihan Longmars ( P 0,191 ). Kesimpulan: tidak terdapat perbedaan
bermakna kadar MDA peserta pelatihan Komando sebelum dan setelah
melaksanakan latihan Longmars. Hal ini kemungkinan disebabkan telah terjadi
adaptasi latihan fisik terhadap kadar MDA yang terjadi selama latihan Longmars.

Background: Physical exercise has been known to provide health benefits.
However, physical exercise as well as the potential negative impact of injury and
oxidative stress. Physical exercise with high intensity and long duration are
considered as one of the factors that cause oxidative stress. Longmarch Exercise is
one of the training materials Commando conducted by trainees Commando
training in forest mountain stage. Longmarch exercises conducted by walking for
8 consecutive days, speed of 5-6 km / h, carrying a load of 35 kg, over varied
terrain (flat, uphill and downhill) and a distance of about 500 miles. Longmarch
exercise as one of procedural activity in the Commando training in a military
environment with long duration and high intensity could be expected to lead to
oxidative stress. Oxidative stress can be determined by examination
malondialdehida (MDA) which is a marker of oxidative stress. Purpose: To
determine the mean levels of MDA and the mean differences MDA levels of
Commando training participants before and after implementing Longmarch
exercise. Methods: Subjects of the study were 30 participants in Commando
training 20-30 years old were randomly selected to follow become respondent of
this research. The research subject is a trained soldier who had been carrying out a
physical exercise program for 1-4 years. The level of MDA examination
performed 1 day prior to the Longmarch exercise and immediately after
completion of the Longmarch exercise. Results: The mean of MDA levels
before Longmarch exercise was 0.729 ± 0.229 nmol / mL, the mean of MDA
levels after Longmarch exercise was 0.655 ± 0.183 nmol / mL. There were no
significant differences in mean of MDA levels before and after Longmarch
exercise (P 0.191). Conclusion: there is no significant difference of the MDA
levels of Commando training participants before and after implementing
Longmarch exercise. This is probably due to the body's adaptation that occur
during Longmarch exercise.
