Summary

The purpose of this study was to verify physiological responses to constant-load (continuous) vs. variable-intensity (interval) during 14 weeks of aerobic exercise on active men. The hypothesis was that would be differences in physiological variables on distinct modes of execution performed on the treadmill over a period of 14 weeks of training.

Detailed description

Initially there were thirty five subjects, but due factors outside the present study, three individuals were excluded from the program. Two individuals during maximal exercise test (VO2) showed clinical impairment test being interrupted by the doctor and the third individual presented a plantar fasciitis in the early familiarization. Thirty two healthy and active males volunteered to participate in the study. All subjects exercised habitually, with at least 1 year experience aerobic training. The Human Ethics Committee of Rio de Janeiro Federal University approved this study (no 58659/02471312.8.0000.5257).The subjects performed a total of nine visits to the laboratory of the Brazilian Navy at City of Rio de Janeiro for physical tests on different days, except between visits I-II and VII-III. The interval between visits was one week between visits II-III-IV and VIII-IX, six weeks between the first day of training and visits V, four weeks between V-VI-VIII. All subjects from interval and continuous groups performed a total of 46 sessions of supervised running program.

Type	Name	Description
OTHER	running training	The present study was designed to compare the physiological effects between the two training regimes and the control group.The subjects from interval and continuous group performed others activities as resistance training, swimming or soccer. Those activities wasn't controlled by our study, but the individual didn't do physical activities at least 3 hours before started our running sessions. The control group simply performed their normal physical activities (resistance training, swimming or soccer). But, each 3 weeks we had a contact with control group to check about any injury or illness that could affect the final results. None were found.
