The main purpose of this study was to assess the changes in energy expenditure (EE), oxygen volume (VO), heart rate (HR), and velocity (V) measurements obtained during three sets of each of two squat training protocols in a group of healthy young adults. Twenty-nine students of Sports Sciences volunteered to participate in this study. They attended the laboratory on four different days and performed four sessions: two of 3 sets of 12 repetitions at 75% 1 repetition maximum (RM) and two of 3 sets of 30 repetitions at 50% 1RM while EE, VO, HR and V was evaluated. The major outcomes of this study indicated that EE, VO2, and HR tended to decrease in both protocols as the sets were performed. Despite this, assessing different strength levels and metabolic variables helps to explain the observed variations in physiological responses. Furthermore, these findings have important implications for the design of effective and personalized strength training programs.
本研究的主要目的是评估一组健康年轻成年人在两种深蹲训练方案中，每组进行三组训练期间所测得的能量消耗（EE）、氧气量（VO）、心率（HR）和速度（V）的变化。29名体育科学专业的学生自愿参与了这项研究。他们在四个不同的日子前往实验室，并进行了四次训练：两次是每组12次重复、共3组，强度为1次重复最大值（RM）的75%；另外两次是每组30次重复、共3组，强度为1RM的50%，同时对EE、VO、HR和V进行评估。本研究的主要结果表明，在两种训练方案中，随着训练组数的增加，EE、VO₂和HR均呈下降趋势。尽管如此，评估不同的强度水平和代谢变量有助于解释所观察到的生理反应差异。此外，这些发现对有效且个性化的力量训练计划的设计具有重要意义。
