Abstract
Background: Aerobics (AE) is an attractive type of aerobic exercise and can be considered as an appropriate intervention strategy for weight loss. However, results of clinical trials are not consistent due to high variability in relation to the type of AE and duration of intervention. Objective: The objective was to investigate the effect of AE on weight and fat mass loss in adult women. Methods: Of the total number of 243 studies, the final analysis included seven clinical trials with a pooled sample size of 242 females. Results: Although the results confirmed a significant overall effect on weight loss (-1.97 kg, 95% confidence interval [-3.72, -0.23], p = .03), an effect on fat mass loss was not confirmed (-2.62%, 95% confidence interval [-5.53, 0.29], p = .08). It was further observed that traditional AE and longer interventions have a greater effect on reducing body weight and fat mass compared with aqua AE and interventions shorter than 10 weeks. Conclusions: In conclusion, AE seems to be an effective intervention for weight loss in women, but the type of AE and the duration of the intervention should be considered.

Obesity has accompanied the human population since historical times
To assess the overall effect of AE on weight and fat mass (FM) loss, 7 randomized clinical trials (RCT) were used, the results of which suggest that traditional AE and interventions longer than 10 weeks have a greater effect compared with interventions including aqua AE or interventions shorter than 10 weeks
The results presented in this paper suggest that interventions longer than 10 weeks are more effective compared with shorter interventions
Summary
Obesity has accompanied the human population since historical times. While at the beginning of the twentieth-century obesity was merely a problem of developed countries (Caballero, 2007), currently the number of obese individuals has dramatically increased around the globe, and this non-communicable disease is referred to as a pandemic (Swinburn et al, 2019). Since 1980, the number of overweight adults has risen by almost 1.2 billion (Ng et al, 2014) This increase is confirmed by the constantly growing mean body mass index (BMI) in almost all countries of the world. Obese women are at a higher risk of associated diseases compared with men (Hu, 2003). These diseases include for example type II diabetes mellitus, dyslipidaemia, obstructive sleep apnoea, hypertension, and cardiovascular diseases (Blair & Church, 2004; Li & Cheung, 2009). Objective: The objective was to investigate the effect of AE on weight and fat mass loss in adult women. Conclusions: In conclusion, AE seems to be an effective intervention for weight loss in women, but the type of AE and the duration of the intervention should be considered
