Abstract

BACKGROUND

the main objective of this study was to evaluate the test-retest reliability of two different functional electromechanical dynamometry (FEMD)-controlled squat training protocols.

METHODS

twenty-eight healthy young adults volunteered to participate in this study. They attended the laboratory on four different days and performed four sessions: two of three sets of 12 repetitions at 75% 1RM and two of three sets of 30 repetitions at 50% 1RM. The range of movement (ROM), mean dynamic strength (MDS), peak dynamic strength (PDS), mean velocity (MV), peak velocity (PV), mean potency (MP), peak potency (PP), work (W), and impulse (I) were recorded. To evaluate the reliability of FEMD, the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and coefficient of variation (CV) were obtained.

RESULTS

reliability was very high for ROM (CV: 3.72%, ICC: 0.95), MDS (CV: 1.09%, ICC: 1.00), PDS (CV: 1.97%, ICC: 1.00), and W (CV: 4.69%, ICC: 1.00) conditions at 50% 1RM and for ROM (CV: 3.90%, ICC: 0.95), MDS (CV: 0.52, ICC: 1.00), PDS (CV: 1.49%, ICC: 0.98), and W (CV: 4.14%, ICC: 1.00) conditions at 75% 1RM and high for the rest of variables at 50 and 75% 1RM.

CONCLUSIONS

this study demonstrates that FEMD is a reliable instrument to measure ROM, MDS, PDS, MV, PV, PV, MP, MP, W, and I during both squat protocols (50 and 75% 1RM) in healthy young adults.

摘要

背景

本研究的主要目的是评估两种不同的功能性电动机械测力（FEMD）控制深蹲训练方案的重测信度。

方法

28 名健康的年轻成年人自愿参加本研究。他们在 4 天内到实验室参加了 4 次测试：2 次 75%1RM 的三组 12 次重复，2 次 50%1RM 的三组 30 次重复。记录了运动范围（ROM）、平均动态强度（MDS）、峰值动态强度（PDS）、平均速度（MV）、峰值速度（PV）、平均功率（MP）、峰值功率（PP）、功（W）和冲量（I）。为了评估 FEMD 的可靠性，获得了组内相关系数（ICC）、测量误差（SEM）和变异系数（CV）。

结果

在 50%1RM 下，ROM（CV：3.72%，ICC：0.95）、MDS（CV：1.09%，ICC：1.00）、PDS（CV：1.97%，ICC：1.00）和 W（CV：4.69%，ICC：1.00）条件下的可靠性非常高，在 75%1RM 下，ROM（CV：3.90%，ICC：0.95）、MDS（CV：0.52，ICC：1.00）、PDS（CV：1.49%，ICC：0.98）和 W（CV：4.14%，ICC：1.00）条件下的可靠性也很高，其余变量在 50%和 75%1RM 下的可靠性也较高。

结论

本研究表明，FEMD 是一种可靠的仪器，可以在健康年轻成年人进行两种深蹲方案（50%和 75%1RM）时测量 ROM、MDS、PDS、MV、PV、PV、MP、MP、W 和 I。
