Tactical athletes need to develop strength and lower limb lean mass (LL LM) to perform effectively. Resistance training (RT) is the most effective way to achieve these goals. Two periodization models stand out: traditional linear periodization (TLP) and daily undulating periodization (DUP).
To verify the effect of lower limb RT with TLP and DUP on isotonic and isokinetic muscle strength and lean mass in tactical athletes.
Thirty-five Brazilian Army military (21.57 ± 2.02 years; 81.81 ± 11.19 Kg; 177.79 ± 6.88 cm) were divided into two treatment groups and one active control group.
The treatment groups performed 9 weeks of supervised RT (18 sessions), consisting of free weight exercises in this order: back squat, squat lunge, deadlift, and stiff legged deadlift. Dynamic isotonic muscle strength, lean mass, and isokinetic knee extension and flexion were assessed at baseline and post treatment period.
There was a significant pre-post difference in dynamic isotonic muscle strength (TLP, P < 0.001; DUP, P < 0.001) and lean mass (TLP, P = 0.034; DUP, P = 0.003) of LL LM in both treatment groups. However, effect sizes (ES) and variations (%Δ) of gains were greater in the DUP group both in muscle strength (TLP, ES = 1.55, %Δ = 30.97; DUP, ES = 2.55, %Δ = 36.02), and in lean mass (TLP, ES = 0.13, %Δ = 2.07; DUP, ES = 0.44, %Δ = 2.95). For isokinetic knee flexion strength, a significant difference was found between the TLP versus CON.
Both lower limb RT periodization models provided gains in muscle strength and lean mass, with a small advantage for the DUP approach. In the isokinetic knee flexion strength, the TLP was more effective.
战术运动员需要发展力量和下肢瘦体重（LL LM）以有效执行任务。阻力训练（RT）是实现这些目标的最有效方法。两种周期化模型脱颖而出：传统线性周期化（TLP）和日常波动周期化（DUP）。
验证 TLP 和 DUP 对战术运动员下肢 RT 对等速和等动肌肉力量和瘦体重的影响。
35 名巴西陆军军人（21.57±2.02 岁；81.81±11.19 Kg；177.79±6.88 cm）分为两组治疗组和一组主动对照组。
治疗组进行了 9 周的监督 RT（18 次），包括以下自由重量练习：深蹲、深蹲弓步、硬拉和直腿硬拉。在基线和治疗后期间评估动态等速肌肉力量、瘦体重和等速膝关节伸展和屈曲。
两组治疗组的动态等速肌肉力量（TLP，P<0.001；DUP，P<0.001）和下肢瘦体重（TLP，P=0.034；DUP，P=0.003）均有显著的前后差异。然而，DUP 组的肌肉力量（TLP，ES=1.55，%Δ=30.97；DUP，ES=2.55，%Δ=36.02）和瘦体重（TLP，ES=0.13，%Δ=2.07；DUP，ES=0.44，%Δ=2.95）的 ES 和增益变化（%Δ）都更大。对于等速膝关节屈曲力量，TLP 与 CON 之间存在显著差异。
两种下肢 RT 周期化模型都提供了肌肉力量和瘦体重的增益，DUP 方法略有优势。在等速膝关节屈曲力量方面，TLP 更为有效。
