ABSTRACT
Purpose:
The purpose of this study was to compare the effects of strength training performed with and without the supervision of a personal trainer on the anthropometric, functional, and biochemical responses of sedentary adults.
Methods:
Overall, 38 sedentary men were divided into 3 groups: control group (n = 12), no personal trainer group (n = 14), and personal trainer group (n = 12). Participants of all groups were submitted to pre-training data collection, including anthropometric evaluation, functional and cardiometabolic tests, and blood collection for biochemical parameters. Then, the subjects were involved in strength training of 50 minutes 3 times per week for 8 weeks. After the strength training program, the participants were submitted to the same data collection.
Results:
The personal trainer group presented a decrease in waist circumference, systolic blood pressure, sum of skinfolds, abdominal resistance, pectoral resistance, one-repetition maximum on bench and leg press compared with the no personal trainer group (p < 0.05). The no personal trainer group had an improvement only in the sum of skinfolds (p < 0.05).
Conclusions:
The results of the present study indicate that 8 weeks of strength training with a personal trainer can produce important changes in body composition and blood pressure in sedentary subjects.
