The purpose of this study was to examine the impact of age on the affective responses (attitude, feelings, self-efficacy, intention, enjoyment, and fondness) after a worksite circuit-style resistance exercise routine in career firefighters.
Nineteen young (25.5 ± 3.3 yr) and 19 middle-aged male career firefighters (50.3 ± 3.5 yr) completed 2 d of physical testing at local fire stations. Participants were familiarized with the resistance training exercises (deadlift, shoulder press, lunge, and upright row) at visit 1 and performed a multirepetition maximum (RM) assessment to prescribe the appropriate loads for the resistance exercise bout on visit 2. The resistance training session included three sets of 8 to 10 repetitions per exercise at 80% 1-RM. Participants completed a postexercise questionnaire examining affective responses and a rating of perceived exertion (RPE). Mann-Whitney U tests and an independent t-test were used to determine differences between the young and middle-aged firefighters' affective responses and RPE, respectively.
There were no significant differences between groups for any of the six affective responses ( P = 0.062-0.819) or RPE ( P = 0.142).
Age did not influence the perceived effort or affective responses following an acute bout of worksite resistance exercise. Firefighters reported overall positive attitudes, feelings, and fondness paired with high self-efficacy and intention at a training frequency of twice per week. However, confidence, intention, and enjoyment decreased at higher training frequencies (i.e., 3-4x per week). Circuit-style resistance training performed twice per week may be a feasible and practical worksite exercise routine across ages in the fire service.
本研究旨在探讨年龄对职业消防员进行现场循环式抗阻训练后的情感反应（态度、感受、自我效能、意愿、享受程度和喜爱程度）的影响。
19名年轻男性职业消防员（25.5±3.3岁）和19名中年男性职业消防员（50.3±3.5岁）在当地消防站完成了为期2天的体能测试。参与者在第1次访视时熟悉了抗阻训练动作（硬拉、肩推、弓步蹲和直立划船），并在第2次访视时进行了多次重复最大重量（RM）评估，以确定抗阻训练回合的合适负荷。抗阻训练课程包括每个动作进行三组，每组8至10次重复，负荷为80%的1-RM。参与者完成了一份训练后问卷，以检查情感反应和主观用力程度（RPE）评分。分别使用曼-惠特尼U检验和独立t检验来确定年轻消防员和中年消防员在情感反应和RPE方面的差异。
在六种情感反应（P=0.062-0.819）或RPE（P=0.142）的任何一项上，两组之间均无显著差异。
年龄并未影响一次急性现场抗阻训练后的主观用力程度或情感反应。消防员报告称，在每周两次的训练频率下，他们总体上持积极态度、有良好感受且有喜爱之情，同时具有较高的自我效能和意愿。然而，在更高的训练频率（即每周3-4次）下，信心、意愿和享受程度会下降。每周进行两次的循环式抗阻训练可能是消防部门各年龄段可行且实用的现场训练方案。
