Introduction: firefighters are public service who live a constant risk due to daily exposure that are submitted by the nature of their work; this risk intensifying the habits of everyday life as it´s physical inactivity.
Objective: To determine the effect of a program of aerobic exercise with karate mode in active firefighters in the city of Chihuahua, on cardiovascular risk reduction and anthropometric measures.
Material and Methods: An exercise program for incremental loads (50-70% FCKarvonen) with a duration of six weeks, monitoring the heart rate with monitor intensity was performed. In 13 males 24-45 years with cardiovascular risk factors according to the NCEP (ATP III). Before and after the exercise program was determined: lipid profile, atherogenic index, cardiovascular risk, restricted anthropometric profile, sum of 6 skinfolds, fat mass, body mass index, waist-hip index and conicity index.
Results: Total cholesterol decreased from 202.54 ± 32.94 mg / dL to 185 ± 30.04 mg / dL (-7.93%) (p <0.01). The VLDL lipoproteins 42.5 ± 28.1 mg / dL to 30.3 ± 16.4 mg / dL (-21.2%) and triglycerides 212.08 ± 140.54 mg / dL to 151.62 ± 81.11 mg / dL (-20.8%) (p <0.05). The atherogenic index decreased 11.6% and cardiovascular risk by 25.27% (p <0.05). Reducing body mass of 100.52 ± 17.46 to 98.72 ± 18.15 kg, decreased BMI 34.54 ± 5.98 to 33.73 ± 6.11 kg / m2, conicity index 1.69 ± 0.06 was observed at 1.65 ± 0.06, all of the above (p <0.01). Reducing body fat percentage of 32.09 ± 7.66% to 30.89 ± 6.53% with p <0.05. Decrease the amount of fat pads of 166.19 ± 145.79 ± 51.64 mm to 36.74 mm and Waist Hip index of 0.99 ± 0.05 to 0.96 ± 0.04, p <0.01.
Discussion: Firefighters are exposed to risks directly related to the work environment, and independently or interacting with others can contribute to development, perpetuation or aggravation of certain heart diseases.
Conclusion: The exercise program reduced cholesterol, VLDL lipoproteins, triglycerides, atherogenic index and cardiovascular risk. Showed improvement in anthropometric parameters (body weight, BMI, body fat percentage, amount of fat pads, waist-hip index and conicity index.
