Resumo: |
Introductions: Traditionally, stimuli for increased strength and cardiorespiratory fitness are prescribed separately based on the different characteristics of the modalities and the adaptations that each promotes. This separation has been questioned by recent studies that suggest that the intensity with which the exercise is performed seems to generate greater influence than the equipment involved. Based on this assumption, the adaptations promoted by physical exercise should be related to the effort and not to the modality in question. Thus, the objective of the present study was to compare the changes in muscle strength and cardiorespiratory fitness promoted by strength and aerobic training, with similar duration. Methods: 25 men (28.9 ± 5.6 years) with experience in strength training (6.6 ± 5.6 years of training) performed a cardiorespiratory effort test and 10 maximal repetitions in knee extensor. After the tests, the participants were randomly divided into a cycle (4 sets of 30 "sprints on stationary bicycle) and Leg Press (4 sets of 10-12 maximum repetitions), three times a week with three minutes and a half interval between sets for 5 weeks. After the training period, the tests were repeated. Results: The peak oxygen consumption ( 2peak) increased 10.2% (p = 0.012) in the BIC group, a significantly higher result when compared to the LP (p = 0.023). Regarding BIC and LP strength levels, there were increases of 17.7 and 22.9%, respectively (p <0.05), with no differences between groups (p = 0.614). Conclusion: The results of the present study suggest that performing sprint in cycle ergometer is more efficient than strength training in leg press because it presented similar increase in strength levels besides a significantly higher increase in cardiorespiratory fitness. |
