This study focused on the psychological and quality of life aspects of resuming alpine skiing practice after total knee arthroplasty (TKA) in elderly skilled skiers. Two data pools were used in order to analyze psychological states: (a) at the beginning, at the end, and 8 weeks after a 12-week skiing intervention; and (b) concerning diurnal variations of states (i.e., skiing days compared with everyday life during intervention and retention phase). In particular, effects of skiing on amount of physical activity and perceived exertion, perceived pain and knee function, and subjective well-being were analyzed using a control group design. Results reveal that the skiing intervention substantially increases the amount of physical activity by the intervention group (122.30 ± 32.38 min/day), compared with the control group (75.14 ± 21.27 min/day) [F (2, 32) = 8.22, P < 0.01, η(2) = 0.34)]. Additionally, the analyses of psychological states demonstrated that skiing goes along with enhanced well-being and no significant impact on perceived pain, exertion or knee function. In sum, alpine skiing can be recommended for older persons with TKA with respect to well-being, perceived pain and knee function, and perceived exertion.
本研究聚焦于老年熟练滑雪者全膝关节置换术（TKA）后恢复高山滑雪练习的心理和生活质量方面。为分析心理状态，使用了两个数据集：（a）在为期12周的滑雪干预开始时、结束时及结束后8周；（b）关于状态的日变化（即干预和维持阶段的滑雪日与日常生活相比）。具体而言，采用对照组设计分析了滑雪对身体活动量、感知运动用力、感知疼痛和膝关节功能以及主观幸福感的影响。结果显示，与对照组（75.14±21.27分钟/天）相比，滑雪干预使干预组的身体活动量大幅增加（122.30±32.38分钟/天）[F（2, 32）= 8.22，P < 0.01，η(2) = 0.34]。此外，心理状态分析表明，滑雪伴随着幸福感增强，且对感知疼痛、运动用力或膝关节功能无显著影响。总之，就幸福感、感知疼痛和膝关节功能以及感知运动用力而言，高山滑雪可推荐给患有TKA的老年人。
