Today's society is aware of the importance of health. Now many people are competing to do physical activity. This is done to prevent the occurrence of diseases such as diabetes, blockage of blood vessels caused by fat. Currently, there are many types of sports, one of which is Electro Muscle Stimulation (EMS). This EMS device uses electrical waves to artificially stimulate muscles. This research method is an experimental pretest-posttest design. The subject is female as many as 10 people. Exercises were carried out using a total body EMS with a duration of 20 minutes for core and 5 minutes for cooling down, performed 2x/week for 6 weeks. The exercise was carried out when the research subjects had enough sleep and the pulse was below 80-110 minutes. The variable in this study was subcutaneous fat with measurements using a simple meter to determine right-left upper arm circumference, abdominal circumference, right and left thigh circumference. The results of this study were that there were significant differences in the circumferences of the upper arms, abdomen and thighs where the results of the SPSS static analysis showed a value of <0.05.
Highlight:Aerobic exercise was reduced body fat and increased free fatty acids.LICT and MICT decreased body fat and increased free fatty acids. Abstract:Overweight is fat imbalances can affect the health. It is one of the problems in many countries, especially Indonesia recorded an increase case in 2007 (8.8%) to 2013 (13.5%). Overweight categorized by 25-30 kg/m2 body mass index in units (Organization 2018). Figures overweight can be pressed to provide some treatments, such as aerobics sports activities. This study aimed to determine the effect of Continuous Low Intensity Training (LICT) and Moderate Intensity Continuous Training (MICT) to decrease body fat content (FM) and increase in free fatty acids (FFA) in overweight women. 18 female subjects completed the study 4X/week exercise LICT or MICT for 5 weeks. LICT and MICT performed for 30 minutes with an additional 5 minutes warm-up and 5 minutes of cooling down with LICT intensity of 60%-70% and MICT 70%-80% of maximum HR where both types of exercise using ergo cycle while measurement FM and FFA were measured before and after practice. LICT occurred decreasing in body fat and increasing in free fatty acids that significant pre and post LICT (p < 0.05). MICT occurred decreasing in body fat and increasing in free fatty acids that significant pre and post MICT (p<0.05). In the second comparison group (LICT and MICT) were decline against body fat and an increased in free fatty acids between workouts Low-Intensity Continuous Training (LICT) greater tendency than Moderate-Intensity Continuous Training (MICT) with delta FM (p = 0.120) and delta FFA (p=0.131) in which the value is >0.05. LICT and MICT was increase while body fat was decreased. The results of a comparison test occur list downward trend in body fat while in free fatty acids was increased.
AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh Low Intensity Continuous Training (LICT) dan Moderate Intensity Continuous Training (MICT) terhadap penurunan kandungan lemak tubuh (FM) dan peningkatan asam lemak bebas (FFA) pada perempuan overweight. Metode, 18 subjek penelitian menyelesaikan 4x/minggu latihan LICT atau MICT selama 5 minggu. LICT dan MICT dilakukan selama 30 menit dengan tambahan waktu 5 menit pemanasan dan 5 menit pendinginan dengan intensitas LICT 60%-70% dan MICT 70%-80% dari HR maksimal dimana kedua jenis latihan tersebut menggunakan ergocycle sedangkan pengukuran FM dan FFA diukur sebelum dan sesudah latihan. Hasil. Pada kelompok LICT terjadi signifakan pada lemak tubuh dan asam lemak bebas dengan tingkat signifikan < 0,05 serta pada kelompok MICT juga mengalami signifikan pada lemak tubuh dan asam lemak bebas dengan tingkat signifikan < 0,05. Pada perbandingan kedua kelompok antara LICT dan MICT secara deskriptif mengalami peningkatan akan tetapi hasil dari analisis tidak ada perbedaan antara kedua kelompok dengan nilai ∆FM (p = 0.120) dan ∆FFA (p = 0.131) yang mana nilai tersebut > 0.05. Kesimpulan. Latihan ini bisa digunakan sebagai penekanan terjadinya overweight di Indonesia dengan pengaturan jadwal latihan lagi.. Kata kunci—Lemak; Asam Lemak bebas; intensitas; Overweight
The main purpose of this study was to compare cycle ergometer training using low intensity and moderate intensity in increasing the catecholamine hormone of overweight females. This study was conducted on 50 overweight females with mean age of 22.44±2.97 years old and body mass index between 25 kg.m.2 to 30 kg.m.2. Treatment was given 4 times per week during 5 weeks periods in Group 1 with low intensity cycle ergometer continuous training (60%-70% HRmax), and Group 2 with moderate intensity cycle ergometer continuous training (70%-80% HRmax). Heart rate was monitored using polar heart rate monitor H10. Pre-test was taken before giving treatment and post-test after giving a treatment by taking blood a day after doing exercise and fasting at night and the blood samples obtained are taken to the laboratory for serum sample analysis. Data were analyzed using paired t-test. The result found that there was an increase in catecholamine hormone in both groups with a p-value of <0.05. It can be concluded that cycle ergometer training using low and moderate-intensity improved catecholamine hormone for overweight females.
