Introduction:
The prevalence of overweight has considerably increased worldwide over the last few decades and is a growing concern among young people and adolescents. Overweight, defined as excessive fat accumulation, has a significant impact on the occurrence of obesity. Adolescent obesity is a serious public health concern. The assessment of physical fitness in overweight women provides substantial information that can be used to maintain and improve their health.

Aim of the Study:
The objective of this study was to analyze the effects of the moderate-intensity continuous training (MICT) on the responses of overweight women.

Material and Methods:
The participants in this study were overweight women (overweight class I with BMI of 23.00- 24.90 kg/m2). This study was conducted on 22 healthy women, all of whom were aged 18.95 ± 0.65 years, with height of 158.18 ± 5.43 cm, weight of 60.50 ± 4.07 kg, and body mass index (BMI) of 24.16 ± 0.48 kg/m2. The study assessed physical capacity of the overweight women to determine body weight (BW), resting heart rate (RHR), BMI, body fat (BF), and oxygen consumption before and after a week of MICT. The training heart rate was evaluated at 60-85% heart rate reserve (HRR) for an eight-week period. The following variables were measured: BW, height, BMI, RHR, BF percentage, and oxygen consumption. The BF percentage was measured using a calculated skinfold thickness (ST). The 20-meter multistage fitness test was used to evaluate oxygen consumption.

Results:
There was a significant difference in BW, RHR, BMI, BF, and oxygen consumption in the MICT group at the end of the training program (p < 0.05).

Conclusions:
The MICT significantly reduced total body composition and improved cardiovascular fitness in overweight individuals. An increase in aerobic physical activity should be considered an important component of a lifestyle modification for prevention and treatment of overweight and obesity in adolescents.
