The aim of the present study was to assess the chronic effects of different order of resistance training cycles on strength and muscle thickness of recreationally resistance-trained men. The study sample was composed of 16 healthy men (age: 25.0 ± 3.8 years, height: 1.77 ± 7.6 cm, total body mass: 81.7 ± 10.4 kg, RT experience: 4.6 ± 0.7 years, relative bench press one repetition maximum: 1.2 ± 0.1, relative squat one-repetition maximum: 1.5 ± 0.2). According to baseline maximal strength, participants were allocated in one of the following groups: Maximal Strength-Strength Endurance (MS-SE) (six weeks of a maximal strength cycle followed by six weeks of a strength endurance cycle); Strength Endurance -Maximal Strength (MS-SE) (six weeks of a strength endurance cycle followed by six weeks of a maximal strength cycle). The following measurements were performed in the pre and post intervention periods: one-repetition maximum (1RM) on parallel back squat and bench press exercises, muscle thickness evaluation of biceps brachialis (MT), triceps brachialis (MT), and vastus lateralis (MT) by ultrasonography. Total load lifted (TLL) and Internal training load (ITL) were also assessed. Both groups presented significant increases in bench press (MS-SE = 0.001, SE-MS = 0.003) and half squat (MS-SE = 0.004, SE-MS = 0.001) 1RM, MT (MS-SE = 0.020, SE-MS = 0.005) and MT (MS-SE = 0.001, SE-MS = 0.001). For MT, a significant increase was observed only for MS-SE group (MS-SE = 0.032, SE-MS = 0.143). No significant difference between groups was observed for any strength or morphological outcomes. In conclusion, both MS-SE and SE-MS training cycles are effective strategies to enhance resistance training adaptations in trained men.
本研究的目的是评估不同顺序的阻力训练周期对进行休闲阻力训练的男性力量和肌肉厚度的长期影响。研究样本由16名健康男性组成（年龄：25.0±3.8岁，身高：1.77±7.6厘米，总体重：81.7±10.4千克，阻力训练经验：4.6±0.7年，相对卧推一次最大重复重量：1.2±0.1，相对深蹲一次最大重复重量：1.5±0.2）。根据基线最大力量，参与者被分配到以下组之一：最大力量-力量耐力（MS-SE）（六周的最大力量训练周期，随后是六周的力量耐力训练周期）；力量耐力-最大力量（SE-MS）（六周的力量耐力训练周期，随后是六周的最大力量训练周期）。在干预前后进行了以下测量：平行背蹲和卧推练习的一次最大重复重量（1RM），通过超声测量肱二头肌（MT）、肱三头肌（MT）和股外侧肌（MT）的肌肉厚度。还评估了总举起负荷（TLL）和内部训练负荷（ITL）。两组在卧推（MS-SE = 0.001，SE-MS = 0.003）和半蹲（MS-SE = 0.004，SE-MS = 0.001）1RM、MT（MS-SE = 0.020，SE-MS = 0.005）和MT（MS-SE = 0.001，SE-MS = 0.001）方面均有显著增加。对于MT，仅在MS-SE组观察到显著增加（MS-SE = 0.032，SE-MS = 0.143）。在任何力量或形态学结果方面，两组之间均未观察到显著差异。总之，MS-SE和SE-MS训练周期都是增强训练有素男性阻力训练适应性的有效策略。
