BACKGROUND & AIMS:
:The purpose of this study was to compare fatigue, strength, body composition, muscle thickness, and muscle quality between Hodgkin's lymphoma survivors (HLS) and apparently healthy subjects matched by age, gender, and physical activity levels (CON). Twelve HLS (32.16 ± 8.06) and 36 CON (32.42 ± 7.64) were enrolled in the study. Fatigue was assessed using the 20-item Multidimensional Fatigue Inventory, muscle strength using an isokinetic dynamometer, body composition using dual-energy X-ray absorptiometry, and thickness and muscle quality using B-mode ultrasound. Differences between HLS and CON were analyzed using independent samples t tests. No significant differences were observed between groups for any demographic characteristics: age ( P = .922), weight ( P = .943), height ( P = .511), body mass index ( P = .796), fat mass ( P = .688), fat-free mass ( P = .520), and percent body fat ( P = .446). No significant differences were observed for strength (peak torque; P = .552), relative peak torque ( P = .200), muscle thickness ( P > .05) and muscle quality ( P > .05). However, self-perceived fatigue was significantly higher in HLS than in CON ( P = .009). It appears that when HLS are matched by age and physical activity levels to CON, no significant difference in body composition, muscle thickness, muscle quality, or strength is observed. Self-perceived fatigue, as predicted, is higher in HLS, which may have implications and should be considered when prescribing exercise training to this cancer population.
背景与目标:
:本研究的目的是比较霍奇金淋巴瘤幸存者(HLS)与显然健康的受试者之间的疲劳,强度,身体成分,肌肉厚度和肌肉质量,并根据年龄,性别和身体活动水平(CON)进行比较。十二项HLS(32.16±8.06)和36 CON(32.42±7.64)被纳入研究。使用20个项目的多维疲劳清单评估疲劳,使用等速测功机评估肌肉强度,使用双能X射线吸收法评估身体成分,并使用B型超声评估厚度和肌肉质量。使用独立样本t检验分析了HLS和CON之间的差异。两组之间在任何人口统计学特征上均未观察到显着差异:年龄(P = .922),体重(P = .943),身高(P = .511),体重指数(P = .796),脂肪质量(P = .688),不含脂肪的质量(P = .520)和体内脂肪百分比(P = .446)。强度(峰值扭矩; P = .552),相对峰值扭矩(P = .200),肌肉厚度(P> .05)和肌肉质量(P> .05)没有明显差异。但是,HLS的自我感觉疲劳明显高于CON(P = .009)。看起来,当HLS通过年龄和身体活动水平与CON相匹配时,在身体组成,肌肉厚度,肌肉质量或强度上均未观察到显着差异。正如预期的那样,HLS中的自我感觉疲劳较高,这可能会产生影响,因此在对此人群进行运动训练时应考虑这一点。
