Lower back, neck and shoulder pain are the most prevalent musculoskeletal problems affecting office workers worldwide, and they have both personal and socioeconomic consequences as well. Several hypotheses regarding the underlying mechanisms and the maintenance behind office work-related musculoskeletal disorders have been presented. There is some evidence, based on epidemiological studies as well as studies upon smaller groups of subjects, that individuals who sit and work for a long time not only show cognitive impairment at the workplace, but also suffer from poorer and fragmented daytime sleep, in addition to increased risks of developing various psychological, physiological and medical impairments and musculoskeletal disorders. The related physical mechanisms behind musculoskeletal disorders are discussed in the context of new findings. The main causes, as well as varying levels in severity of musculoskeletal disorders,not to mentionthe link between such disorders in the neck, shoulder and lower back regions and physical activity among office workers are also stated. The main objective of this review paper is to conduct a systematic review to identify musculoskeletal disorders and how these disorders are
correlated with physical activity among office workers. The results of this review indicate that the musculoskeletal disorder is a critical issue among office workers and the main cause is related to the absence of physical activity as well as the subjects’ sedentary lifestyle. As a practical message, regular physical activity can be effective in the prevention and decrease of physical discomfort among office workers who suffer from musculoskeletal pain.

Nowadays, people have realized that physical activity plays a critical role in determining the health and wellness of an individual. This is proven by the extensive research on this area, which indicates that people have started to emphasize this matter. In addition, it is also well known that motivation is one of the main factors that determine whether people will participate in performing physical activity or not. Both extrinsic and intrinsic motivators play a major role in determining levels of physical activity. Therefore, this study is made to investigate the relationship between extrinsic motivation and physical activity level. The researcher randomly selected 195 students from SMK Alam Megah 2, Seksyen 28, Shah Alam, Selangor as respondents for this study. The method of this study includes a questionnaire adapted from International Physical Activity Questionnaire (IPAQ) and Exercise Motivation Inventory (EMI), which was edited to fulfil the requirements of this study. The results from this study show that there is a positive and significant relationship between extrinsic motivation and physical activity.

Physical Activity and Aging Research: A Bibliometric Analysis

Müller AM, Ansari P, Ebrahim NA, Khoo S

J Aging Phys Act, 2016 07;24(3):476-83.
PMID: 26671908 DOI: 10.1123/japa.2015-0188

Physical activity and aging research has burgeoned in the past few decades. However, despite the increase in scholarly publications, no attempts have been made to summarize the publication landscape and identify work that has had great impact on physical activity and aging research. We conducted a bibliometric analysis and collected publication data from 1980 to February 6, 2015, in the Web of Science Core Collection. Of 9,935 publications, most were published after 2007 and almost 60% were in the category of geriatrics and gerontology or sport sciences. Highly cited publications (n = 45) were mostly authored by researchers from US institutions and were quantitative in nature. Publications that reported on the associations between physical activity and health, or effects of physical activity on health, in older adults made up 60% of the highly cited publications. We expect more scholars from various backgrounds and geographical regions to join the conversation on physical activity and aging.

Fulltext The determinants of participation in physical activity in Malaysia

Cheah YK, Poh BK

Osong Public Health Res Perspect, 2014 Feb;5(1):20-7.
PMID: 24955308 DOI: 10.1016/j.phrp.2013.12.002

Objectives: In light of the importance of physical activity, the aim of the present study is to examine the factors affecting participation in physical activity among adults in Malaysia.
Methods: A logistic regression model and the Third National Health and Morbidity Survey consisting of 30,992 respondents were used.
Results: Age, income, gender, education, marital status, region, house locality, job characteristics, and medical conditions are significantly associated with participation in physical activity. In particular, old individuals, high income earners, females, the well-educated, widowed or divorced individuals, East Malaysians, urban dwellers, the unemployed, and individuals who are not diagnosed with hypercholesterolemia are less likely to be physically active than others.
Conclusion: Because sociodemographic and health factors play an important role in determining physical activity, the government should take them into account when formulating policy.

Fulltext Motivation influence towards physical activity level among university staff

Kamal AA, Radzani M

Movement Health & Exercise, 2016;5(1):49-56.
MyJurnal

Levels of physical activity are usually affected by a high motivational factor. There are many internal and external motivational factors. Less physical activity or a sedentary lifestyle can be defined as movement of the body equal to the minimum rest metabolic rate. It also refers to passive physical behavior such as watching television, reading, using a computer, talking on the phone, driving a car, meditating, or eating. This study was conducted to determine and investigate the motivational factors that influence participation in sports and physical activities. A survey questionnaire based on the "Exercise Motivation Inventory" (EMI-2) and the "International Physical Activity Questionnaire" (IPAQ) was developed to meet the needs of the study. This study looked at the relationship between motivational factors and the level of physical activity and sports participation among university staff, who involved in their daily lives. Findings that showed university staff were more motivated to perform moderate physical activity in daily life. The motives for physical activity are both in terms of appearance and social factors. Inferential analysis indicated no significant difference in terms of the motives for employee engagement in physical activity and status based on weight. Correlation analysis showed a significant relationship between physical activity and body weight among staff. There was no significant relationship between participation motives and physical activity among employees.

The purpose of this study is to look at the effects of music during physical activities towards the mood of primary school children. The results of this study show a result that found a positive mood effect during physical education activities by incorporating music elements in teaching and teaching sessions. The study was conducted for two weeks. A week-long three Physical Education subject sessions per session take about 30 minutes. This study was conducted on primary school pupils in Seremban which involves
three (n = 3) schools, focusing on schools in rural areas only encompassing one hundred and eighty (n = 180) ie 90 pupils men and 90 girls. All nine-year study subjects were broken down into three groups ie control groups A, B, and C. The study was experimental. Group A follows the Three Year syllabus syllabus provided by the Curriculum Development Division of the Ministry of Education, which is applicable in primary schools in Malaysia. Group B runs free games that are not tied to curriculum syllabus and Group C similar
to group A also follow the same syllabus of the Year Three syllabus but during the lesson the pupils are played with the background of music in each learning session. The findings show that the C group absorbed by the music element shows the tendency of a better and positive mood compared to other groups. The results of this study also attract the children to participate in the Physical Education class more actively and give positive impact to the individual in terms of the development of their gross motor and is a fun subject and lead to the formation of a balanced, physical, emotional, spiritual, and intellectuality.

Introduction: Validation of instruments is essential when assessing physical activity (PA). The aim of this study was to validate a Malay language version of the International Physical Activity Questionnaire (IPAQ-M) against Actical accelerometer and to determine its reliability and validity.
Methods: A total of 90 Malay adults aged 35-65 years old participating in The Malaysian Cohort project were recruited for this study. The IPAQ-M is comprised of 12 items, covering vigorous, moderate, walking, sitting and sleeping activities, and was administered on two occasions (Day 1 and Day 9) by interviewing the participants. Participants wore the Actical accelerometer for seven consecutive days between the two interview sessions. Results Validity tests showed that time spent in moderate-vigorous physical activity (MVPA) (min/wk) from IPAQ-M was significantly correlated with MVPA from accelerometer (rho=0.32, p<0.01). Time spent in vigorous activity (rho=0.44) and total activity (rho=0.36) from IPAQ-M were significantly correlated (p<0.01) with that measured by accelerometer, but no correlation was observed for sedentary behaviour. Reliability tests revealed significant correlations between the two interview sessions for all intensities of PA (rho=0.55 to 0.71, p<0.01). Bland-Altman plots showed that time spent in MVPA for IPAQ-M was significantly different from that measured by accelerometer (mean difference: 98.02 min/wk; 95% limits of agreement: -785.33 to 1317.83 min/wk; p<0.01). When classifying people into meeting PA recommendation, the agreement between the two instruments was fair (κ=0.22).
Conclusions The IPAQ-M has acceptable validity for MVPA, vigorous and total physical activity, and was reliable for assessing the physical activity of Malay adults.

MyJurnal

Shift in the dispersion of breast cancer population continues to be a major health concern for women in the developing countries. However, prevalence and associated factors of physical activity among this population have not been explored in Malaysia. This study determined the profile and factors associated with physical activity in the breast cancer women. A multi-center cross-sectional survey was conducted among 399 breast cancer women. Socio-demographic questionnaire was used to generate socio-demographic and clinical data. Physical activity was assessed using the international physical activity questionnaire (IPAQ-SF). Sociodemographic variables were summarized by descriptive statistics. Factors associated with physical activity were identified using Logistic regression analyses. Majority of the participants were married (83.9%), had surgery (92.4%) and menopause (74.1%). The overall physical activity prevalence was 39.4%. Non formal education (Adjusted Odds Ratio [AOR] 5.80; 95%CI: 1.65, 52.15;p=0.017), having had surgery (AOR 0.18; 95%CI: 0.04, 0.79; p=0.023),

Axial Segmental Coordination During Turning: Effects of Stroke and Attentional Loadings

Manaf H, Justine M, Goh HT

Motor Control, 2017 Jan;21(1):42-57.
PMID: 26595318 DOI: 10.1123/mc.2015-0040

Attentional loadings deteriorate straight walking performance for individuals poststroke, but its effects on turning while walking remain to be determined. Here we compared turning kinematics under three attentional loading conditions (single, dual-motor, and dual-cognitive task) between stroke survivors and healthy controls. Nine chronic stroke survivors and 10 healthy controls performed the Timed Upand- Go test while their full-body kinematics were recorded. Onset times of yaw rotation of the head, thorax and pelvis segments and head anticipation distance were used to quantify turning coordination. Results showed that stroke survivors reoriented their body segments much earlier than the controls, but they preserved the similar segmental reorientation sequence under the single-task condition. For the healthy controls, attentional loading led to an earlier axial segment reorientation, but the reorientation sequence was preserved. In contrast, the dual-cognitive task condition led to a disrupted reorientation sequence in stroke. The results indicate that turning coordination was altered in individuals poststroke, especially under the dual-task interference.

Fulltext Non-face-to-face physical activity interventions in older adults: a systematic review

Müller AM, Khoo S

Int J Behav Nutr Phys Act, 2014;11(1):35.
PMID: 24612748 DOI: 10.1186/1479-5868-11-35

Physical activity is effective in preventing chronic diseases, increasing quality of life and promoting general health in older adults, but most older adults are not sufficiently active to gain those benefits. A novel and economically viable way to promote physical activity in older adults is through non-face-to-face interventions. These are conducted with reduced or no in-person interaction between intervention provider and program participants. The aim of this review was to summarize the scientific literature on non-face-to-face physical activity interventions targeting healthy, community dwelling older adults (≥ 50 years). A systematic search in six databases was conducted by combining multiple key words of the three main search categories "physical activity", "media" and "older adults". The search was restricted to English language articles published between 1st January 2000 and 31st May 2013. Reference lists of relevant articles were screened for additional publications. Seventeen articles describing sixteen non-face-to-face physical activity interventions were included in the review. All studies were conducted in developed countries, and eleven were randomized controlled trials. Sample size ranged from 31 to 2503 participants, and 13 studies included 60% or more women. Interventions were most frequently delivered via print materials and phone (n=11), compared to internet (n=3) and other media (n=2). Every intervention was theoretically framed with the Social Cognitive Theory (n=10) and the Transtheoretical Model of Behavior Change (n=6) applied mostly. Individual tailoring was reported in 15 studies. Physical activity levels were self-assessed in all studies. Fourteen studies reported significant increase in physical activity. Eight out of nine studies conducted post-intervention follow-up analysis found that physical activity was maintained over a longer time. In the six studies where intervention dose was assessed the results varied considerably. One study reported that 98% of the sample read the respective intervention newsletters, whereas another study found that only 4% of its participants visited the intervention website more than once. From this review, non-face-to-face physical activity interventions effectively promote physical activity in older adults. Future research should target diverse older adult populations in multiple regions while also exploring the potential of emerging technologies.

Physical activity, fitness and the energy cost of activities: implications for obesity in children and adolescents in the tropics

Lau XC, Chong KH, Poh BK, Ismail MN

Adv. Food Nutr. Res., 2013;70:49-101.
PMID: 23722094 DOI: 10.1016/B978-0-12-416555-7.00002-3

The tropics cover a large section of the world in which both developed and developing countries are situated. Rapid socioeconomic development, modernization, urbanization, and globalization have affected both the food market and physical activity (PA), which in turn have propelled the obesity epidemic in the tropics. There is growing concern that overweight and obesity are emerging as major health problems among children and adolescents in the tropics, despite the fact that undernutrition still exists in many of these countries. Physical inactivity, a low metabolic rate, and lack of physical fitness (PF) have been linked to overweight and obesity. Moreover, PF in several tropical countries is declining, and these changes may be a threat to future health, as low PA and PF levels are important risk factors for noncommunicable chronic diseases. Previous studies have reported that the relationships among PA, PF, overweight, and obesity are inconsistent and inconclusive. There is no indication that variances in the energy cost of physical activities lead to obesity. Despite a lack of definite evidence to prove a causal relationship, there is enough certainty that physical inactivity and low fitness levels are linked to overweight and obesity. Hence, people living in tropical countries need to be encouraged to lead a healthier lifestyle by increasing their PA levels and reducing sedentary behaviors to prevent overweight or obesity.

Fulltext Physical activity and associated factors among young adults in Malaysia: an online exploratory survey

Sreeramareddy CT, Majeed Kutty NA, Razzaq Jabbar MA, Boo NY

Biosci Trends, 2012 Jun;6(3):103-9.
PMID: 22890157 DOI: 10.5582/bst.2012.v6.3.103

The burden of non-communicable diseases is increasing in Malaysia. Insufficient Physical Activity, which is an important risk factor for non-communicable diseases, is less researched in Malaysia. We aimed to assess the level of physical activity and identify its correlates. An online survey was carried out during October, 2011 in the University Tunku Abdul Rahman by the opinion poll research committee. Young adults answered the Short International Physical Activity Questionnaire and a questionnaire about factors according to a socio-ecological model which was adapted from published studies. Metabolic equivalent (MET)-hours and MET-minutes were calculated. Physical activity was classified as sufficient when MET-minutes were > 840. The mean age of the 474 participants was 22.4 years (S.D. = 4.7), and 253 (53.4%) were females. Their mean and median of MET-hours of PA done during the previous seven days were 31.36 (S.D., 52.19) and 14.7 (IQR, 5.77-32.07), respectively. Physical activity done was sufficient among 242 (51.1%) participants. Using univariate analysis, being male, good self-rated health, positive intention, self-efficacy, perceived benefits, social support, and availability of facilities were associated with sufficient physical activity. Using multivariate analysis sufficient physical activity was associated with participants' intention (OR 0.75, 95% CIs 0.64, 0.88), self-efficacy (OR 0.91, 95% CIs 0.85, 0.97) and facility availability (OR 0.81, 95% CIs 0.73, 0.91). The proportion of participants with sufficient physical activity was low. Positive intention and self-efficacy associated with sufficient physical activity should be supported by availability of facilities and a safely-built environment. A nationwide survey about physical and associated socialecological factors is needed to design rational health promotion strategies.

Fulltext Factors influencing physical activity level among secondary school adolescents in Petaling District, Selangor

Aniza I, Fairuz MR

Med J Malaysia, 2009 Sep;64(3):228-32.
PMID: 20527274 MyJurnal

Physical activity is the first line approach and one of the main factors in preventing chronic diseases. Currently there is the increasing percentage of sedentary life style or lack of exercise among adolescents. The main objectives of the study were to determine the prevalence of inactivity and the factors influencing physical activity in adolescents. A cross sectional study was carried out among secondary school students aged 14 and 16 in Petaling District, Selangor, Malaysia. A total of 519 respondents participated in this study. Their physical activity level was measured using the International Physical Activity Questionnaire (IPAQ). The active group was classified as those having levels of equal or more than 600 met-min per week while less than 600 met-min per week was considered inactive. Response rate in this study was 95.4%. The prevalence of inactive in adolescents was 20.8%. Female adolescents, non-working mother, time constraint, exercise only when having ample time and stretching before exercise are predictor factors for being inactive among adolescents. Steps need to be taken to persistently ensure that the physical activity among adolescents be increased continuously.

Validity of a children's physical activity questionnaire (cPAQ) for the study of bone health

Nor Aini J, Poh BK, Chee WS

Pediatr Int, 2013 Apr;55(2):223-8.
PMID: 23253297 DOI: 10.1111/ped.12035

BACKGROUND: The aim of this cross-sectional study was to examine the ability of a children's physical activity questionnaire (cPAQ) to assess physical activity levels and bone health status of school children.
METHODS: Subjects consisted of 90 pre-pubertal and early pubertal children aged 9-10 years. Components of physical activity were assessed using metabolic intensity (METPA) scores and mechanical bone strain (MECHPA) scores. An Actical accelerometer was used to validate METPA scores among a sub-sample of 57 children. Reliability was assessed by test-retesting all children after a 7 day interval. Whole body bone mineral content (BMC) was measured using dual-energy X-ray absorptiometry.
RESULTS: The reliability of cPAQ for assessment of various categories of physical activity was moderate to high (r ranged from 0.55 to 0.68, P < 0.001). Agreement was fair for repeated use of the cPAQ (Cohen's kappa = 0.32, P < 0.001). Bland-Altman plots show cPAQ had fair agreement only for moderate activity (mean difference 35.4 min/week; 95% limits of agreement -434.0 to +504.9 min/week). Approximately 69.6% of children were correctly classified (into the same or adjacent quartiles) according to the quartiles of BMC for METPA score, and 58.7% were correctly classified according to MECHPA score. Only 10.9% and 12.0% of children were grossly misclassified as compared to METPA and MECHPA scores, respectively.
CONCLUSIONS: The cPAQ has reasonable validity in assessing moderate physical activity, and it demonstrates good ability to accurately classify children according to BMC. It fails, however, to assess other activity levels, suggesting that objective measurement is still a better method of assessment of physical activity among primary school children.

The Physical Activity Scale for the Elderly (PASE): Validity and Reliability Among Community-Dwelling Older Adults in Malaysia

Ismail N, Hairi F, Choo WY, Hairi NN, Peramalah D, Bulgiba A

Asia Pac J Public Health, 2015 Nov;27(8 Suppl):62S-72S.
PMID: 26058900 DOI: 10.1177/1010539515590179

Physical Activity Scale for the Elderly (PASE) is among the frequently used self-reported physical activity assessment for older adults. This study aims to assess the validity and reliability of a Malay version of this scale (PASE-M). A total of 408 community-dwelling older adults were enrolled. Concurrent validity was evaluated by Spearman's rank correlation coefficients between PASE with physical and psychosocial measures. Test-retest reliability was determined by the intraclass correlation coefficient (ICC). The mean PASE-M scores at baseline and follow-up were 94.96 (SD 62.82) and 92.19 (SD 64.02). Fair to moderate correlation were found between PASE-M and physical function scale, IADL (rs = 0.429, P < .001), walking speed (rs = 0.270, P < .001), grip strength (rs = 0.313-0.339, P < .001), and perceived health status (rs = -0.124, P = .016). Test-retest reliability was adequate (ICC = 0.493). The Malay version of PASE was shown to have acceptable validity and reliability. This tool is useful for assessing the physical activity level of elderly Malaysians.

The effects of toe-out and toe-in postures on static & dynamic balance, risk of fall and TUG score in healthy adults

Khan SJ, Khan SS, Usman J

Foot (Edinb), 2019 Jun;39:122-128.
PMID: 30580888 DOI: 10.1016/j.foot.2018.06.002

BACKGROUND: Toe-in and toe-out foot positions have not yet been tested for dynamic balance and risk of fall. The aim of this study was to investigate the effects of these two modifications on static and dynamic postural stability and risk of fall through instrumental (Biodex Balance System®) and functional (timed up and go-TUG test) tools.
METHODOLOGY: Twenty healthy adults (8 males, 12 females, age: 29±4.10years, BMI: 21.56±2.36kg/m2) participated in this study. Static and dynamic (levels 8 and 2) balance with single stance and double stance and dynamic (level 8 and levels 6-2) for risk of fall with double stance were tested with the Biodex Balance System with three self-selected feet positions: straight (13.8°), toe-out (35.6°) and toe-in (-11.9°) for each test condition. Additionally, TUG test was performed with toe-out and toe-in gait.
RESULTS: The results of repeated measures ANOVA showed significant differences (p<0.05) between straight and modified toe angles in balance at dynamic level 2 with both double and single stance conditions. Significant differences (p<0.001) were also found in TUG scores for the test conditions.
CONCLUSION: Toe-in and toe-out gait modifications have significant effects on balance at higher levels of platform tilt and functional balance. Further investigations with knee osteoarthritis patients and electromyography may provide insight in balancing strategies adopted by the body in toe-out and toe-in gait.

Reliability and validity of the Malay International Physical Activity Questionnaire (IPAQ-M) among a Malay population in Malaysia

Chu AH, Moy FM

Asia Pac J Public Health, 2015 Mar;27(2):NP2381-9.
PMID: 22593217 DOI: 10.1177/1010539512444120

The International Physical Activity Questionnaire (IPAQ) was developed to assess the physical activity patterns in populations. The authors aim to examine the reliability and validity of the Malay version of IPAQ (IPAQ-M). The IPAQ-M was self-administered twice at a 1-week interval to assess its test-retest reliability. Criterion validity was assessed between the IPAQ-M and a 7-day physical activity log (PA-Log). A total of 81 Malay adults participated in the study. Intraclass correlation coefficients (ICC), kappa (κ), correlation coefficients (ρ), and Bland-Altman plot were used for data analyses. The ICC scores revealed moderate to good correlations (ICC = 0.54-0.92; P < .001) on items categorized by intensities and domains and a κ of 0.73 for total activity. Validity results from the PA-Log were statistically significant (P < .001) across intensities and domains (ρ = 0.67-0.98). The IPAQ-M demonstrated good reliability and validity for the evaluation of physical activity among this Malay population.

Influence of different substrate moistures on wood consumption and movement patterns of Microcerotermes crassus and Coptotermes gestroi (Blattodea: Termitidae, Rhinotermitidae)

Wong N, Lee CY

J Econ Entomol, 2010 Apr;103(2):437-42.
PMID: 20429460

Moisture is an important physical factor for the survival of termites. The effects of different moisture levels (0, 5, 10, 15, 20, and 25%) of a sand substrate on the behavior of laboratory groups of Microcerotermes crassus Snyder and Coptotermes gestroi (Wasmann) (Blattodea: Termitidae: Rhinotermitidae) were evaluated. Moisture content of sand affected wood consumption and influenced termite distribution across a moisture gradient for M. crassus. Changing the moisture parameters affected the location preference of C. gestroi, but the effect on wood consumption was not significant. Nonetheless, M. crassus and C. gestroi showed a similar distribution pattern of association with particular moisture levels.
