395 Macedo et al. Periodized model for prescribed exercises Int J Cardiovasc Sci. 2018;31(4)393-404 Original Article One repetition maximum test The 1RM test was carried out by one of the instructors from the HCC rehabilitation service. It was defined as the heaviest weight that can be moved in an exercise with no more than one repetition. Before starting the test, all subjects performed a 5-minute general warm-up of cycling and, after that, they carried out 10 repetitions with no additional load to adjust the speed and angle of movement. First, the instructor explained how to carry out each movement. The 1RM test was done encompassing the large muscle groups (quadriceps, hamstrings, pectoral, biceps, triceps and large dorsal), and the weight was increased by 5 kg at every repetition, with 3-5 minutes of rest between lifts after three to four subsequent attempts. The test was interrupted when the patient was unable to complete the one repetition with the proposed load, and, in this case, the previous load was considered the ideal one. The MEGAMOVEMENT station was used for the test in the following positions: extensor chair, leg curl, hip adduction and abduction, bench press, biceps and triceps curl, and high pulley rear. Body composition evaluation The body composition (Bc) was evaluated by a rehabilitation instructor. The Faulkner protocol was composed of six circumferencemeasures (calf, thigh, arm, forearm, hip, and abdomen) and four skinfold measures (abdomen, suprailiac, subscapular and triceps). 15 A tape measure (Wisomodel R88) was used combined with an adipometer (Cescorf). Fat percentages, ideal body mass, lean and fat masses were calculated using the Faulkner equation. 17 The volunteers were reevaluated after 36 sessions (MAC + CPT + 1MR + Bc). Experimental design This studywas a randomized controlled trial, inwhich 62 male patients were included and randomly assigned to two groups: a non-periodized training group (NPG, n = 33) and a periodized exercise training group (PG, n = 29). Blinded scaled envelopes were prepared with papers named PG and NPG and kept secure by an independent person (Figure 1). Figure 1 - Study design. PG: periodized exercise training group; NPG: non-periodized exercise training group; LEVF: left ventricular ejection fraction; RM: maximum resistance.
