A multi-component assessment model for monitoring training distress among athletes

Abstract

We report the initial validation of a multi-component assessment model for monitoring training distress among athletes. The model combines measures of mood disturbance with measures of perceived stress and symptom intensity. Altogether, 492 athletes completed the 10-item Perceived Stress Scale (PSS-10; Cohen et al., 1983), the 24-item Brunel Mood Scale (BRUMS; Terry et al., 2003), and a checklist of 19 symptoms associated with acute overtraining (Fry et al., 1994). Six training distress factors were identified by an exploratory factor analysis: “depressed mood”, “perceived vigour”, “physical symptoms”, “sleep disturbance”, “perceived stress”, and “general fatigue”. Comparisons of group means of these factors with a previously validated inventory were consistent with theoretical predictions and provided evidence of construct validity. Internal consistency of the subscales was also confirmed, with Cronbach alphas ranging from 0.72 to 0.86. Together, these findings suggest that this multi-component model provides a sound conceptual basis for the assessment of training distress among athletes.

中国国家女子马拉松队备战柏林世界田径锦标赛生理生化指标的变化特征

以中国国家女子马拉松队7名运动员为研究对象,对运动员在备战柏林世界锦标赛期间平原准备阶段、高原训练阶段和赛前平原准备阶段的血液指标(白细胞、血红蛋白、血清睾酮、肌酸激酶、血尿素)和机能指标(血压、晨脉)进行监控。总结在备战柏林世锦赛期间生理、生化指标的变化特点,探索适合我国女子马拉松运动员的训练模式。研究发现,高原训练期间要有节奏地安排训练负荷,不同训练负荷性质的内容要穿插进行,尤其是在高原训练的强化期,生理生化指标的变化较为明显,应当增加训练监控的密度,避免过度训练的发生;同时赛前高原训练阶段、赛前平原训练阶段大负荷强度的训练,必须建立在雄厚的有氧代谢能力基础上,否则运动员很难完成持续性的高强度的训练负荷。

Exercise training increases the S-Klotho plasma levels in sedentary middle-aged adults: A randomised controlled trial. The FIT-AGEING study

ABSTRACT

This study aimed to investigate the effects of different training modalities on the soluble Klotho (S-Klotho) plasma levels in sedentary middle-aged adults. A total of 74 middle-aged adults (53.4 ± 5.0 years old; 52.7% women) were enrolled in the FIT-AGEING study. We conducted a 12-week randomised controlled trial. The participants were randomly assigned to 4 different groups: (i) a control group (no exercise), (ii) a physical activity recommendation from the World Health Organization group (PAR), (iii) a high intensity interval training group (HIIT), and (iv) a high intensity interval training group adding whole-body electromyostimulation training group (HIIT-EMS). S-Klotho plasma levels, anthropometric measurements, and body composition variables were measured before and after the intervention programme. All exercise training modalities induced an increase in the S-Klotho plasma levels (all P ≤ 0.019) without statistical differences between them (all P ≥ 0.696). We found a positive association between changes in lean mass index and changes in the S-Klotho plasma levels, whereas a negative association was reported between changes in fat mass outcomes and changes in the S-Klotho plasma levels after our intervention study. In conclusion, our results suggest that the link between exercise training and the increase in S-Klotho plasma levels could be mediated by a decrease of fat mass and an increase of lean mass.
