UNAIR NEWS – Cardiovascular is the number 1 cause of death globally that kill people worldwide with risk factors for dyslipidemia and obesity. Dyslipidemia is a condition of increased levels of fat in the blood, which is characterized by an increase in LDL cholesterol and a decrease in HDL cholesterol. While obesity is a condition where there is an increase in fat mass in the body.
Aerobic is one form of aerobic exercise that is quite popular in the community and fitness centres. The impact of this exercise on the modulation of risk factors for heart disease is unknown. Therefore Purwo Sri Rejeki, Dr., M. Kes. and the team wants to prove that the combination of low and high impact movements can affect the modulation of risk factors for heart disease, namely LDL cholesterol levels and HDL,
“My team and I conducted a study with one group pretest and posttest design with 19 female subjects, aged 19-25 years, with a BMI ranging from 23-24.5 kg / m2. “Fun aerobic intensity is done 3 times/week for six weeks, for 45 minutes/session,” explained the lecturer who won the best graduate of Universitas Airlangga in 2007.
Measurement of Kol-LDL and Kol-HDL was carried out before and after the whole exercise process. The intervention (pretest) blood sampling was done in the morning before aerobic and before fasting. Whereas posttest, blood is drawn done the day after the last aerobic fun and the previous night also fasted.
The results of Kol-HDL and Kol-LDL measurements showed an increase before doing aerobic fun and afterwards. The HDL / LDL ratio before fun aerobic (0.51 ± 0.06) and posttest (0.64 ± 0.09) showed a significant increase in protection against the incidence of cardiovascular disease after fun aerobics.
“Aerobic movements are used by activating the upper and lower parts of the body. “The implementation of the core part of the sport is done progressively from a single movement in the upper body then simultaneously to the whole body,” he said.
A physical activity carried out with fun aerobics has been shown to activate the transport of fatback from the tissues to the liver through increased levels of HDL. The results obtained are encouraging results because with an increase in HDL levels, a decrease in LDL and an increase in the HDL / LDL ratio means lowering risk factors for heart disease.
“Hopefully, this method can be an alternative to reduce the risk of heart disease in the future. Thus, cardiovascular or heart disease is no longer a scourge for humans, “he hoped.
