Purpose: The purpose of this study is to investigate the impact of walking at different speeds with wearing unstable shoes on the movement of the lower limbs, and to provide relevant biomechanical supports for fitness and injury prevention. Methods: Twelve females volunteered to join the test. The walking speed was respectively 0.80 m/s, 1.20 m/s and 1.70 m/s. The kinematic parameters of the lower limb of ankle, knee and hip measured with Vicon motion analysis system. And univariate repeated measurements of variance analysis was used to measure the effect of unstable shoes in lower limbs joints in three differences speeds. Results: The movement pattern of the hip joint is relatively stable and is less affected by the speed. It is mainly manifested in the extension, abduction and external rotation of the hip joint. The knee joint is affected by the walking speed, especially in the coronal plane and the horizontal plane. The angle range of motion of the ankle joint are larger than hip joint, there have increased of the dorsiflexion, inversion and internal rotation in ankle joint. Conclusion: For the lower extremities of the hip, knee and ankle joints, with the increase of walking speed, joint angle and range of activities also showed varying degrees of increase; and joint angle peaks are in the pre-support period.

Running and jogging are listed as two of the most popular outdoor leisure activities for adults (The Outdoor Foundation 2017). Male and female adult runners attending a four-day workshop conducted by the authors from 2007–2018 indicated that learning how to be lifelong runners was their primary goal for attending the workshop. These recreational runners with an average age of 50 years, who attended one of the 20 workshops, were chosen for the study to see how successful they had been years later in pursuit of their goal of lifelong running and what changes in training and health they had incurred. The study surveyed workshop participants to examine their running frequency, injuries, body weight changes, and supplemental training as they aged. Among respondents there was no difference in the percentage who are still running with regard to age and sex. Comparisons of those runners 60 years old and over with those under 60 years of age were made to see if there were differences in how their running activities had changed over 10 years. Current runners 60 and older reported running “less frequently.” There was no significant difference in running interruption due to injury in those 60 and over compared to those under 60. Two-thirds of the runners had a normal BMI classification in strong contrast to national norms. Nearly ninety percent were cross-training to supplement their running. These former workshop participants have been able to continue their favorite physical activity and enjoy running after the age of 60 and beyond.
跑步和慢跑被列为成年人最受欢迎的两项户外休闲活动（the outdoor Foundation 2017）。2007年至2018年，参加由作者举办的为期四天的研讨会的男性和女性成年跑步者表示，学习如何成为终身跑步者是他们参加研讨会的主要目标。这些平均年龄为50岁的休闲跑步者参加了20个研讨会中的一个，他们被选中参加这项研究，以了解多年后他们在追求终身跑步目标方面取得了多大成功，以及他们在训练和健康方面发生了什么变化。该研究调查了研讨会参与者，以检查他们的跑步频率、受伤情况、体重变化以及随着年龄的增长而进行的补充训练。在受访者中，仍在跑步的比例在年龄和性别方面没有差异。将60岁及以上的跑步者与60岁以下的跑步者进行比较，看看他们的跑步活动在10年内的变化是否存在差异。目前60岁及以上的跑步者报告说跑步“频率较低”。与60岁以下的人相比，60岁及以下的人因受伤而中断跑步的情况没有显著差异。三分之二的跑步者的BMI分类正常，与国家标准形成鲜明对比。近90%的人进行交叉训练以补充跑步。这些以前参加研讨会的人在60岁及以上的时候能够继续他们最喜欢的体育活动，并享受跑步。

Purpose: The aim of this study was to analyze plantar pressure during the open stance forehand (OSF) in female tennis players. Methods: Seven female players executed the tennis forehand technique with open stance in the biomechanical laboratory. A portable pressure insole system was adopted to collect mean pressure (MP), peak pressure (PP), force (F), pressure-time integral (PTI) and contact area (CA) in 7 regions of the feet. Independent sample T-test was used to analyze the difference among these parameters. Results: F, PP in the first phalangeal region (BT) and the remaining four toe regions (OT) of the right foot (RF) were both larger than the left foot (LF); F in the fourth and fifth metatarsophalangeal joint (M4-5), the middle foot region (MF), hind foot region（HF）and PP in M4-5 of LF were significantly greater than the same region in RF; MP in BT and OT of RF showed significantly higher pressure than LF. While MP among areas of M4-5 and HF of LF was significantly greater than RF; PTI, CA in OT, M4-5 and MF of RF were significantly higher than LF while M1, M2-3, M4-5 and MF of LF showed significant smaller. Conclusion: RF role was to generate the power and LF role was to stabilize the balance of the body during the OFS. However, long-term and repeated open stance was likely to lead to the overuse injuries in the regions of M1 and HF of both feet.

The primary characteristics of Autism Spectrum Disorder (ASD) fall into three broad categories: communication problems, difficulty relating to people, things and events, and repetitive body movements and behaviours (American Psychiatric Association, 2014). Unfortunately, potential barriers for children and youth (5–17 years old) with ASD achieving the recommended 60 minutes of physical activity (Canadian Society of Exercise Physiology, 2012) may be due to characteristics of the condition and/or the lack of specific guidelines for this population. The purpose of the current study was to explore the influence families and physical activity programming has on the physical activity patterns of children with ASD. The perspectives from both family members of children with ASD, and from instructors of physical activity programs for children with ASD were obtained. The participants completed questionnaires and participated in semi-structured one-on-one interviews. Two themes emerged from the data describing physical activity for children with ASD (1) physical activity, regardless of ability, and (2) the nature of ASD: programming and family challenges. Given the rich data collected, this paper will focus solely on the second theme. Two subthemes developed: “So how do we modify that activity”, and “It can be fantastic and then it can just be like a total nightmare”. Overall, this research indicated unique challenges for physical activity participation for children with ASD and provided suggestions on improvements to physical activity programming. Considering various challenges to physical activity for this population, physical activity instructors play a vital role in delivering effective programs for children with ASD.

Objective: Type 2 Diabetes Mellitus (T2DM) is chronic health disease characterized by the body’s inability to produce or use the hormone insulin to regulate blood glucose levels. Individuals with diabetes have an increased risk of medical complications. This review sought to systematically assess if physical activity based on interventions improved health outcomes and reduced the risk for complications in individuals with T2DM. Method: Electronic databases such as MEDLINE, PsycINFO, and CINAHL were searched using a systematic search strategy for randomized controlled trials investigating the efficacy of physical activity in improving health outcomes or reducing the risk of morbidity and mortality from diabetes related complications in individuals with type 2 diabetes. The inclusion criteria search period was between 2008 to 2018. Result: Of the 300 articles initially identified, only 15 manuscripts met the inclusion criteria. 13 of the studies showed physical activity improved glycemic control and reduced HbA1c to suitable levels in individuals with elevated levels of glycemic resistance. Conclusion: This small number of studies (15 studies) suggests physical activity may improve glycemic control and health outcomes and reduce the risk of cardiovascular morbidity and mortality in individuals with Type 2 Diabetes. However, more research is needed for the efficacy of physical activity on co-morbidities.

Vitamin D plays an extremely crucial role for the development, growth, and maintenance of a healthy skeleton, and vitamin D deficiency is a contribute factor for osteoporosis and relating fractures. The purpose of this study was to conduct a review that elucidated vitamin D status and bone mineral density in the elderly through reviewing the literatures. English-language searches of the electronic databases in Google Scholar, ScienceDirect and PubMed were conducted from 1960 to April 2019, using the following search terms: ‘Vitamin D status’, ‘bone mineral density’, ‘osteoporosis’ and ‘the elderly’. This study is of eighteen papers, the majority of subjects are from Europe, with 11 studies (55%) investigating the association between the vitamin D status and BMD on them. The overall results of this study found no consistent association between the serum 25(OH)D concentration and BMD in elderly people. Several factors, such as races, countries, measuring means, and different lifestyle habits would have an impact on vitamin D status and its relationship with BMD.

Background: Regular physical activity (PA) and low sedentariness have significant long-term health benefits. Achieving and measuring adequate levels of PA are difficult in office environments. This study’s primary aim was to evaluate PA levels and sedentariness within work and home settings. The accuracy of self-reported physical activity and accelerometer use acceptability were also determined. Methods: 121 university staff, students and fellows (faculty) gave informed consent. Pre-study questionnaires on PA, sedentary time, mood and sleep were completed. Using a FitBit One accelerometer PA was monitored for 7 days. Steps were counted. PA intensity was categorized as light or moderate-to-vigorous (MVPA). Group differences were compared with Spearman’s and Pearson’s correlation tests. Results: Average pre-study activity estimation was 1.18 hrs/day (SD: 0.622) (95%CI ± 0.049). Subsequently, each participant averaged 1.49 hrs/day (SD: 0.98) walking; (70.9 mins/day (SD: 45.0) moderate activity (3–5 Metabolic Equivalents (METs); 20.5mins/day (SD: 17.2) vigorous activity (>5METs). Average daily sedentary time was 654.6 min (±152.3), with average time at work standing or in very light activity as 6.47 hrs (SD: 4.3 hrs) ( Conclusion: All participants achieved near recommended PA levels. Work and home environments contributed reciprocally to daily totals. Significant differences between self-reported and measured PA levels indicates that both should be recorded.

Background: Hundreds of randomized controlled studies have documented the effectiveness of Tai Chi (TC) to alleviate symptoms from varied medical conditions. Researchers, however, have called for alternate methods to discern participants’ perspectives and to provide additional information regarding the TC protocols, TC teachers’ qualifications, and the social contexts for learning and practicing TC. Purpose: This naturalistic study was designed to explore the perspectives of an experienced TC practitioner and those of her TC teachers as they reflected upon her 9-year journey with TC as she faced varied medical crises. Methods: Using an ethnographic approach, participant observation, the researcher observed participant’s TC classes, conducted in-depth, semi-structured interviews with the participant and her teachers and informal interviews in the field. Context: Participant was a 72-year-old female, who had suffered from spinal stenosis, hip arthritis, and bladder cancer. The participant attended two types of TC classes: a therapeutic Tai Chi (TTC) including a modified short form (10 forms) taught by a physical therapist and a traditional TC class including the Yang style short form taught by a Tai Chi practitioner with 50 years of experience. Findings: 1) TCC provided explicit cues and links between TC and functional fitness, improving the participant’s balance, daily life activities, and increased exercise efficacy and resilience; 2) TC provided a novel challenge motivating the participant’s continued practice while learning complex TC movements. 3) Traditional TC classes provided a supportive community, facilitating a meditative stance, and enabled the participant to subdue the “monkey mind” of a terminal cancer diagnosis.

The purpose of the present study was to assess weight control practices, body image, exercise habits and body composition among college students. 81 female and 20 male participants (age: 21 ± 1 yrs, Body Mass Index (BMI): 23 ± 3 kg/m², body fat percentage (BF%): 22 ± 5%) were recruited. Participants were asked to complete the following questionnaires: 69-item Multidimensional Body-Self Relations Questionnaires (MBSRQ-69), Weight Control Practices (WCP), Exercise Dependence Scale (EDS) and Sedentary Behavior (SBQ). Participants were divided into four groups based on gender classifications of BF%. Appearance Evaluation, Fitness Evaluation and Orientation, Overweight Preoccupation, Self-Classification of Weight, and Body Area Satisfaction subscales of MBSRQ were significantly different (p 0.05). Participants with higher BF% engaged in more WCP. College students with higher body fat were less satisfied with their body image and therefore engaged in more weight control practices.

Participants were asked to complete the following questionnaires: 69-item Multidimensional Body-Self Relations Questionnaires (MBSRQ-69), Weight Control Practices (WCP), Exercise Dependence Scale (EDS) and Sedentary Behavior (SBQ). Participants were divided into four groups based on gender classifications of BF%. Appearance Evaluation, Fitness Evaluation and Orientation, Overweight Preoccupation, Self-Classification of Weight, and Body Area Satisfaction subscales of MBSRQ were significantly different (p 0.05). Participants with higher BF% engaged in more WCP. College students with higher body fat were less satisfied with their body image and therefore engaged in more weight control practices.","PeriodicalId":32633,"journal":{"name":"Physical Activity and Health","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48190145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
