Comparison of the Validity of Four Fall-Related Psychological Measures in a Community-Based Falls Risk Screening

Abstract

We examined the measurement properties of fall-related psychological instruments with a sample of 133 older adults (M age = 74.4 years, SD = 9.4). Measures included the Comprehensive Falls Risk Screening Instrument, Falls-efficacy Scale-International (FES-I), Activities-specific Balance Confidence (ABC), modified Survey of Activities and Fear of Falling in the Elderly (mSAFFE), Consequences of Falling (CoF), Physical Activity Scale for the Elderly (PASE), and 36-Item Short-Form Health Survey (SF-36). The FES-I, ABC, mSAFFE, and CoF were significantly correlated with each other, with SF-36, and with mobility. The ABC and mSAFFE were significantly correlated with PASE. The ABC differentiated between fallers and nonfallers and predicted total falls risk. Findings can assist with the selection of psychological instruments in a falls risk screening context.     

Construct validation of physical activity surveys in culturally diverse older adults: a comparison of four commonly used questionnaires

The purpose of this study was to establish validity evidence of four physical activity (PA) questionnaires in culturally diverse older adults by comparing self-report PA with performance-based physical function. Participants were 54 older adults who completed the Continuous Scale Physical Functional Performance 10-item Test (CS-PFP10), Physical Activity Scale for the Elderly (PASE), HAMPS Physical Activity Questionnaire for Older Adults, Yale Physical Activity Survey (YPAS), and modified Baecke questionnaire. The total PASE score, three outcome scores for the CHAMPS, and three summary indices for the YPAS were significantly correlated with total CS-PFP10 score. The modified Baecke exhibited no correlations with CS-PFP10 scores. The PASE, CHAMPS, and YPAS appear to be the most valid PA self-report questionnaires for culturally diverse older adults.     

12周惯性哑铃练习对轻度认知损害老年人的干预效果

目的观察12周惯性哑铃练习对轻度认知损害(MCI)老年人认知功能、身体活动能力、生活质量和睡眠质量的影响,并探讨认知改善与其他功能改变之间的关系。方法将45名MCI老年人随机分为干预组(n=22)和对照组(n=23)。干预组受试者进行惯性哑铃练习(3次/周,60 min/次,持续12周),对照组不进行运动干预。结果 12周后,干预组受试者阿尔茨海默病评定量表-认知部分(ADAS-Cog)总分/指令得分、蒙特利尔认知评估量表(MoCA)评分、起立行走计时(TUG)和SF-36健康调查问卷(SF-36)心理总得分均显著改善(均P<0.05)。与对照组相比,干预组受试者ADAS-Cog总分/单词回忆得分/注意力得分、简明精神量表(MMSE)评分、TUG和匹兹堡睡眠指数(PSQI)的改善程度均具有显著差异(P<0.05或P=0.05)。偏相关分析结果显示,SF-36心理总得分改变(r=-0.712)、PSQI改变(r=-0.380)与认知改善程度均呈显著负相关。结论 12周惯性哑铃练习可显著提高MCI老年人的认知功能,并对其移动能力、生活质量和睡眠质量具有积极影响,且心理和睡眠改变程度可能影响认知功能的改善效果。

Aerobic training alone or combined with strength training affects fitness in elderly: Randomized trial

Abstract

Purpose: To investigate if combined strength and aerobic training can enhance aerobic capacity in the elderly to a similar extent as aerobic training alone when training duration is matched. Methods: Elderly men and women (age 63.2?±?4.7) were randomized into two intervention groups: an aerobic group (AG, n?=?17) and a combined group (CG, n?=?16). Subjects trained 40?minutes three times a week for 12 weeks. Both groups trained 20 minutes at 65% of heart rate reserve on ergometer cycles followed by another 20 minutes on the ergometer cycles for AG and 20-minute strength training for the lower body for CG. The primary outcome was VO₂max. Secondary outcomes were maximal voluntary contraction (MVC) in isometric knee extension, 1 repetition maximum in three leg exercises, body fat, waist-to-hip ratio, blood pressure and score on the Health Survey Short Form 36 (SF-36). Results: Both groups improved VO₂max (p?<?.01) and MVC (p?<?.001). VO₂max increased 17% confidence interval (CI) [7.4–26] in CG and 26% CI [14.1–38.2] in AG, with no significant difference between groups. MVC increased 22% CI [16.3–27.7] in CG and 9% CI [4.6–13.5] in AG with CG improving MVC more than AG (p?<?.01). CG's score on the general health dimension on the SF-36 health survey improved more than AG's score. Conclusion: Elderly can substitute a part of their aerobic training with strength training and still improve VO₂max to a clinically significant degree when strength training is performed with large muscle groups subsequently to the aerobic training. Combined training additionally improves strength and self-assessed general health more than aerobic training alone.     

Quality of Life Assessment for Physical Activity and Health Promotion: Further Psychometrics and Comparison of Measures

Despite the clear relationship between physical activity and quality of life, few sound, relevant quality of life measures exist. Gill and colleagues developed a 32-item quality of life survey, and provided initial psychometric evidence. This study further examined that quality of life survey in comparison with the widely used short form (SF-36) health survey. Participants (n = 446) completed the quality of life survey, short form (36) health survey, World Health Organization quality of life measure, satisfaction with life scale, and the Godin physical activity measure. All quality of life survey scales (emotional, social, spiritual, physical, activities of daily living, cognitive, integrated) were internally consistent (alpha .79–.95) and test–retest correlations ranged from .68 to .82. The SF-36 had similar internal consistency, slightly lower test–retest correlations, and weaker relationships with satisfaction with life scale. Quality of life survey scales correlated with matching SF-36 and World Health Organization quality of life measure subscales supporting convergent validity. The quality of life survey reflects positive health models better than the SF-36, and is more appropriate for research and programs that focus on physical activity and health promotion.     

Leisure time physical activity in Australian women: relationship with well being and symptoms

This paper explores the association between moderate levels of physical activity (PA) and health benefits in well being and symptoms such as tiredness, back pain, and constipation. Participants in the Australian Longitudinal Study on Women's Health, 14,502 young women (ages 18-23 years), 13,609 middle-age women (45-50 years), and 11,421 older women (ages 70-75 years), answered questions about vigorous and less vigorous exercise (used to determine a physical activity score), well being (SF-36), symptoms, and medical conditions. There were significant associations between the PA score and SF-36 in each cohort. Odds ratios (OR) for a range of symptoms and conditions were lower for women who reported low to moderate activity than for sedentary women, for example, for young women or for constipation = 0.76 (CI, 0.65-0.89), for middle-age women or for tiredness = 0.70 (0.63-0.78). There was no threshold of PA at which health benefits increased significantly. Although cross-sectional, the findings suggest that low-to-moderate levels of exercise are associated with a range of health benefits for women of all ages. These preliminary findings will be followed up during the longitudinal study.     

间歇运动对高血压患者生存质量及血浆CRAMP的影响

目的比较大强度间歇运动和中等强度持续运动对高血压患者生存质量及血浆CRAMP的影响规律。方法26名原发性高血压患者经适应性训练后随机分为两组,分别进行中等强度的持续有氧练习(CE组)和较大强度的间歇有氧练习(IE组)16周,试验开始和结束时分别进行生存质量的评价和外周血CRAMP的测定。结果运动干预后两组患者SF-36量表各维度评分中,躯体疼痛和社会功能与干预前比较无显著性差异(P>0.05);而躯体功能、躯体角色、总体健康状况、活力、情感角色和心理健康6项指标与运动干预前比较都存在显著性差异(P<0.05)。治疗后SF-36量表各维度评分,其4项指标:总体健康状况、活力、情感角色和心理健康,IE组均高于CE组(P<0.05);IE组CRAMP在运动后出现了明显下降(P<0.05),但CE组CRAMP在运动后下降不明显(P>0.05)。结论高强度间歇运动与中等强度持续均能提高高血压患者的生存质量,但间歇运动的效果更好,且可以降低高血压患者外周血衰老信号分子CRAMP水平;间歇运动是高血压患者运动干预的重要方式。     

普拉提对慢性非特异性颈痛的疗效研究

目的:探讨普拉提运动对慢性非特异性颈痛患者的影响。方法:42名符合条件的受试者被随机分置于实验组(n=21),给予每周3次,为期6周的普拉提干预,对照组(n=21)不进行任何干预,实验前和实验结束后24h内进行相关指标的测量。结果:疼痛指标两组具有非常显著性差异(P<0.01),实验组疼痛下降明显;功能障碍指数组间具有非常显著性差异(P<0.01);SF-36中对身体疼痛和精力的影响组间具有非常显著性差异(P<0.01),生理机能、生理职能、一般健康状况、社会功能、情感职能、心理健康方面具有显著性差异(P<0.05)。结论:普拉提运动对慢性非特异性颈痛患者的治疗具有积极疗效。     

Lack of Relationship Between Functional and Perceived Quality of Life Outcomes Following Pulmonary Rehabilitation

Individuals with chronic obstructive pulmonary disease (COPD) have been shown to benefit from participation in pulmonary rehabilitation (PR) programs that include exercise training and education. Purpose: To examine the relationship between improvements in 6 minute walk distance and perceived quality of life in individuals with COPD following completion of a PR program. Methods: The records of 139 individuals completing a PR program (3 times a week for 8 weeks) were retrospectively examined. Prior to entry and upon completion of the program each individual completed a 6 minute walk test (6MWT), the SF-36 Health survey, and the UCSD Shortness of Breath Questionnaire (SOB). SF-36 results were analyzed according to 8 subscales [Physical Functioning (PF), Role Physical (RF), Bodily Pain (BP), General Health (GH), Vitality (V), Social Functioning (SF), Role Emotional (RE), and Mental Health (MH)]. Results: PR resulted in significant improvements in 6MWTdistance (Pre = 845 ± 37 ft, Post = 1127 ± 32 ft, p < 0.001), PF (p < 0.001), RF (p = 0.001), Vitality (p = 0.002), SF (p < 0.001), RE (p = 0.037), MH (p < 0.001) and SOB (Pre = 53 ± 2, Post = 47 ± 2, p < 0.001). The change in 6MWT distance was not related to changes in PF (r = 0.17), RF (r = 0.03), GH (r = 0.03), Vitality (r = −0.001), SF (r = 0.01), RE (r = 0.06), MH (r = −0.04) or SOB (r = 0.12). The magnitude of improvement in 6MWT distance (68%) was much greater than that observed in PF (15%), RF (16%), GH (6%), VT (18%), SF (20%), RE (14%), MH (14%), or SOB (8%). Conclusions: PR has a positive impact on 6 minute walk distance and perceived quality of life in individuals with COPD; however, changes in 6 minute walk distance appear to have no relationship to changes in perceived quality of life.     

Psychological effects of rapid weight loss and attitudes towards eating among professional jockeys

We examined the psychological effects of rapid weight loss among a sample of 41 professional jockeys (mean age 30.9 years, s = 7.0). Participants completed the Brunel Mood Scale (BRUMS) and the Eating Attitudes Test-26 (EAT-26) to establish the relationships between rapid weight loss, mood, and attitudes towards eating. These instruments were administered on three occasions: at the jockeys' minimal weight (achieved through rapid weight loss), their optimal riding weight (when they were not excessively restricting their weight and felt healthy), and their relaxed weight (when there were no forthcoming light rides or no rides at all). It was hypothesized that when riding at minimal weight, jockeys would record a more negative mood profile compared with scores recorded at optimal or relaxed weights. The same trend was expected for eating attitudes. These hypotheses were supported as jockeys reported significantly more negative mood profiles and eating attitudes at minimal weight. The EAT-26 scores indicated the presence of disordered attitudes towards eating at this weight. These results suggest that jockeys' endeavours to reach the minimum weight limit stipulated by governing bodies are likely to jeopardize their psychological well-being. Dialogue surrounding the appropriateness of current weight regulations is therefore encouraged.     

职业女子篮球运动员联赛准备期损伤特征调查研究——以江苏女子篮球运动员为例

目的：通过对江苏女子篮球运动员在联赛准备期中损伤特征的研究,为有效控制职业女子篮球运动员的损伤风险提供研究依据。方法：以备战2018-2019年WCBA联赛的14名江苏女子篮球运动员为研究对象,通过sRPE监控运动员的训练负荷,通过跟踪调查记录运动员的损伤情况,分析训练负荷对损伤的影响。结果：江苏女子篮球运动员的慢性损伤率为100%,非接触性急性损伤高于接触性急性损伤,健将级运动员的损伤风险显著高于一级运动员（P=0.020）;sRPE与基于Polar心率带的训练负荷得分（r=0.644,P=0.000）有显著性强相关;以中等负荷组（491~590 AU）为参照,低负荷组（98~490 AU）损伤风险有所降低（OR=0.912）,而高负荷组（591~676 AU）的损伤风险（OR=2.174）和极高负荷组（677~1 219 AU）的损伤风险（OR=1.692）有所增大,其中高负荷组的损伤风险显著性上升（P=0.040）。结论：职业女子篮球运动员普遍患有慢性损伤,好发非接触性损伤,损伤部位以膝关节、足踝部和腰部为主;健将级运动员比一级运动员发生损伤的风险明显更高;中等负荷的训练课下运动员有较低的损伤风险,但减少负荷并不能有效降低损伤风险;相反增大负荷会使损伤风险显著增加,而进一步增大负荷时损伤风险又会有所下降。     

SF-36量表在老年人运动健身效果评价中的应用

SF-36量表是评价生存质量的一种有效工具，为了促进其在运动健身效果评价中的应用，以北京市普通老年人（男61～65岁；女56～60岁，各300人）为研究时象，从可行性、信度和效度3个方面对SF-36量表在运动健身效果评价中的适用性问题进行了探讨。研究发现：SF-36量表具有令人满意的可行性、信度和效度，但是社会功能维度的信度和效度存在一定的不足。提示：SF-36量表可以用于老年人运动健身过程中时生存质量的评价，但是，建议根据我国的文化背景，结合老年人的心理特征和思维方式对社会功能维度进行适当的修改。SF-36量表作为一个简便高效的生存质量测量工具在体育科研领域中将具有广泛的应用前景。     

Heat production and storage are positively correlated with measures of body size/composition and heart rate drift during vigorous running

The purposes of this study were to determine the relationships between: (a) measures of body size/composition and heat production/storage, and (b) heat production/storage and heart rate (HR) drift during running at 95% of the velocity that elicited lactate threshold, which was determined for 20 healthy recreational male runners. Subsequently, changes in skin and tympanic temperatures associated with a vigorous 20-min run, HR, and VO2 data were recorded. It was found that heat production was significantly correlated with body mass (r = .687), lean mass (r = .749), and body surface area (BSA, r = .699). Heat storage was significantly correlated with body mass (r = .519), fat mass (r = .464), and BSA (r = .498). The percentage of produced heat stored was significantly correlated with body mass (r = .427), fat mass (r = .455), and BSA (r = .414). Regression analysis showed that the sum of body mass, percentage of body fat, BSA, lean mass, and fat mass accounted for 30% of the variability in heat storage. It was also found that HR drift was significantly correlated with heat storage (r = .383), percentage of produced heat stored (r = .433), and core temperature change (r = .450). It was concluded that heavier runners experienced greater heat production, heat storage, and core temperature increases than lighter runners during vigorous running.     

Improved Health-Related Quality of Life After Lung Volume Reduction Surgery and Pulmonary Rehabilitation

Purpose: It has been hypothesized that lung volume reduction surgery (LVRS) and pulmonary rehabilitation improve health-related quality of life (HRQOL). The purpose of this study was to test the hypothesis by examining the long-term functional consequences and general health status of patients with emphysema who have undergone LVRS and pulmonary rehabilitation. Methods: Forty-nine subjects with severe emphysema, aged 51 to 84 years old, post-LVRS and pulmonary rehabilitation participated in this study. Subjects reported changes in physical and mental domains on the Medical Outcomes Study 36-Item Short Form Health Survey (MOS SF-36) over 3 time periods: prior to surgery, 6 months postsurgery, and 18 months postsurgery. The population as a whole was studied and both gender and age were analyzed as subsets. Subjects participated in an intensive 2-week (10 daily sessions) pulmonary rehabilitation program following LVRS. Results: Subjects showed significant improvements in both the physical and mental component summaries at Time 2 (3 months post-LVRS through 6 months post-LVRS) and Time 3 (12 months post-LVRS through 18 months post-LVRS) when compared to Time 1 (pre-LVRS). On the mental component summary scale, subjects younger than 65 years old had significant improvement compared to subjects 65 years and older at Time 3 (P < .05). Women significantly improved more than men at Time 3 on the physical component summary scale (P < .05). Conclusions: Lung volume reduction surgery and 2 weeks (10 daily sessions) of intensive pulmonary rehabilitation appears to improve HRQOL in people with emphysema up to at least 18 months postsurgery. What these data further suggest is that even after declines in health, women can improve HRQOL later in life, and that greater focus should be given to the emotional needs of our older patients.Key Words: lung volume reduction surgery, rehabilitation, quality of life     

步行锻炼对更年期焦虑症患者生活质量的影响

为了进一步观察步行锻炼对更年期焦虑症患者焦虑水平的影响和步行锻炼对更年期焦虑症患者生活质量的影响。对41例更年期焦虑症患者每天进行30 min以上的匀速步行锻炼,持续2个月,同时给予药物治疗。40例对照组仅进行药物治疗。于开始步行锻炼和药物治疗前以及治疗结束后1周内,分别采用汉密尔顿焦虑量表（HAMA）对两组患者进行焦虑水平评定分析,采用健康调查简易量表（SF-36）评定其生活质量。结果表明：两组HAMA评分均下降,但步行锻炼组下降程度较对照组更显著（P〈0.01）。治疗后两组患者SF-36各维度评分均较治疗前明显提高;治疗后步行锻炼组SF-36大部分项目评分明显高于对照组（P〈0.05）,其中MH的差异具有非常显著性意义（P〈0.01）,但BP的差异无显著性（P〉0.05）。结论：短期步行锻炼能显著改善更年期焦虑症患者的焦虑水平,提高患者的生活质量。     

Health benefits of hard martial arts in adults: a systematic review

Participation in organized sports is promoted as a means of increasing physical activity levels and reducing chronic disease risk in adults. Hard martial arts practice (i.e. using body contact techniques), has gained in popularity over time. This review explores the evidence for health benefits of “hard” martial arts practice within the adult population. A systematic electronic database search was conducted, and quality assessments applied the Effective Public Health Practice Project tool. Twenty-eight studies met the inclusion criteria, examining balance, cognitive function, muscular skeletal status, psychological, cardiovascular fitness, and metabolic effects. The majority of studies reported positive effects resulting from hard martial arts practice, showing some improvement and maintenance of balance, cognitive function and psychological health. Benefits may be obtained regardless of the age of practice commencement. However, quality of the evidence is affected by methodological weaknesses across the studies. “Hard” martial arts seem to have potential to improve balance and cognitive functions that decline with age, which can lead to poorer health outcomes among the elderly (e.g. cognitive decline, falls and fractures). Benefits should be further investigated with improved intervention studies, representative samples and longer follow-up periods in order to establish associations with morbidity and mortality in the long term.     

Psychological effects of rapid weight loss and attitudes towards eating among professional jockeys

Abstract

We examined the psychological effects of rapid weight loss among a sample of 41 professional jockeys (mean age 30.9 years, s = 7.0).

The same trend was expected for eating attitudes. These hypotheses were supported as jockeys reported significantly more negative mood profiles and eating attitudes at minimal weight. The EAT-26 scores indicated the presence of disordered attitudes towards eating at this weight. These results suggest that jockeys' endeavours to reach the minimum weight limit stipulated by governing bodies are likely to jeopardize their psychological well-being. Dialogue surrounding the appropriateness of current weight regulations is therefore encouraged.     

Land-walking vs.water-walking interventions in older adults:Effects on aerobic fitness

Background:Low cardiorespiratory fitness is an independent predictor of all-cause and cardiovascular mortality,and interventions that increase fitness reduce risk.Water-walking decreases musculoskeletal impact and risk of falls in older individuals,but it is unclear whether water-walking improves aerobic fitness in the same way as weight-dependent land-walking.This randomized controlled trial involved 3 intervention groups—a no-exercise control group(CG),a land-walking(LW)group,and a water-walking(WW)group—to investigate the comparative impacts of LWandWWto CG on fitness.Methods:Both exercise groups attended individually tailored,center-based,intensity-matched 3×weekly sessions for 24 weeks,which progressed to 150 min of exercise per week.This was followed by a 24-week no-intervention period.Maximal graded exercise tests were performed on a treadmill at Weeks 0,24,and 48.Results:Maximal oxygen uptake increased from Week 0 to Week 24 in both exercise groups(0.57±0.62 mL/kg/min,0.03±0.04 L/min for LW;0.93±0.75 mL/kg/min,0.06±0.06 L/min for WW,mean±SE)compared to the CG(-1.75±0.78 mL/kg/min,-0.16±0.05 L/min)(group×time,p<0.05).Time to exhaustion increased significantly following LW only(123.4±25.5 s),which was significantly greater(p=0.001)than the CG(24.3±18.5 s).By Week 48,the training-induced adaptations in the exercise groups returned to near baseline levels.Conclusion:Our study supports current physical-activity recommendations that 150 min/week of moderate-intensity exercise produces improvements in fitness in previously sedentary older individuals.Also,LW andWW elicit similar improvements in fitness if conducted at the same relative intensities.Exercise-na?ve older individuals can benefit from the lower impact forces and decreased risk of falls associated withWWwithout compromising improvements in cardiorespiratory fitness.
