    Balanced between good diet and regular physical activity is among the important factors in avoiding unhealthy weight gain. Our objective in this study was to investigate the amount of calorie loss against a variety of running exercises. In this study, an experiment on running as a calorie burning physical activities was conducted. Two factors were selected, the distance, and the level of difficulties. The result and statistical analysis concluded that both factors play significant roles in burning calories, with distance as being the most significant factor. The findings also suggest that other than increasing the distance, choosing a hilly terrain when training can give more efficient calories burn. There is no interaction between distance and the level of difficulties. Individuals should plan their workout accordingly only after knowing how many calories they burned through each activity. For individual with aims to burn more calories, an increase in distance and a hilly terrain is more favorable.

    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.

    INTRODUCTION: Knee osteoarthritis (OA) is a weight-bearing joint disease and is more common in overweight and obese persons. The objective of this study was to determine the role of rehabilitation exercises (REs) of lower limbs on weight, functional strength, and exercise adherence in overweight and obese knee OA patients.

    MATERIALS AND METHODS: The patients were recruited from the urban community of Lahore, Pakistan. The patients were divided into the rehabilitation group (RG) and control group (CG). The patients in the RG performed the REs of lower limbs and followed the instructions of daily care (IDC), while the patients in the CG only followed the IDC for a 12 weeks period. Outcome measures were assessed at pre-test before grouping and post-test after 12-weeks of interventions. The measures included: weight, functional strength, and exercise adherence. The Paired Samples t-test (for normally distributed data) and the Wilcoxon Signed Ranked Test (for data that was not normally distributed) were used to analyze the differences within groups from pre to post-test measurements. The variance 2 × 2 factors and the Mann Whitney U-test were used to analyze the difference in weight and functional strength between the groups.

    RESULTS: The patients in the RG reported a statistically significant weight reduction (p < 0.001) and improvement in the functional strength (p < 0.001) within a group. Similarly, the patients in the CG also reported a significant improvement in the scores of functional strength (p = 0.004) within a group. The improvement in the scores of functional strength was higher in the patients of RG than the CG (p < 0.001). Similarly, the patients in the RG reported a statistically significant reduction in weight than the CG (p < 0.001).

    CONCLUSION: The REs could improve weight, functional strength and exercise adherence.

    Background and Objectives: Cognitive performance is essential for children, given this is a critical stage of brain growth and development. This systematic review and meta-analysis aimed to ascertain if physical activity or micronutrients impact cognitive performance in children. Materials and Methods: Electronic databases (PubMed and Scopus®) were searched for relevant articles published between 2012 and 2021. We emphasized randomized controlled trials (RCTs) that examined the effect of physical activity and micronutrients on cognitive performance. Data from eligible studies were gathered and evaluated using random-, fixed- or pooled-effects models with 95% confidence intervals (95% CI). Results: Physical activity appeared to improve both Mathematics (d = 1.12, 95% CI: 0.56, 1.67) and attention (d = 0.65, 95% CI: 0.15, 1.14) performances. The micronutrient vitamin B12 had a positive effect on Mathematics (d = 2.39, 95% CI: 0.79, 3.98), English (d = 5.29, 95% CI: 2.76, 7.83), Geography (d = 5.29, 95% CI: 2.76, 7.83), Science (d = 3.39, 95% CI: 2.62, 4.16) and Arts (d = 3.32, 95% CI: 1.84, 4.79). Zinc was found to positively affect English (d = 3.78, 95% CI: 0.44, 7.13), Geography (d = 4.77, 95% CI: 0.56, 8.98) and Arts (d = 2.39, CI: 0.33, 4.45). Iron positively affected Mathematics (d = 1.29, 95% CI: 0.54, 2.06), English (d = 1.29, 95% CI: 0.44, 7.13), Geography (d = 4.77, 95% CI: 0.56, 8.98) and Arts (d = 2.39, 95% CI: 0.33, 4.45). Conclusions: A more comprehensive intervention with a specific dose/level of physical activity, an increased range of cognitive performance, and a well-designed study design that accounts for dietary intake and other health outcomes are required for future studies.

    Sleep is a crucial factor in healthy aging. However, most middle-aged adults experience high levels of sleep disorders. While previous findings have suggested exercise training could benefit the quality of sleep, the effects of multi-component exercise on sleep quality are less examined. Accordingly, the current study aimed to assess the effectiveness of a multi-component exercise program on the quality of sleep among middle-aged adults. Twenty-four middle-aged adults were randomly assigned either to a multi-component exercise (MCE) group or a control group. The participants in the MCE group attended a 90-min session per week for 12 weeks. The control group was instructed to maintain their daily routine for 12 weeks. The primary outcome was the sleep quality evaluated by the Pittsburgh Sleep Quality Index (PSQI). The secondary outcome was physical fitness, including muscular strength and endurance, balance, and flexibility. Regarding sleep quality, the global mean score (p = 028), sleep disturbances (p = 011), and sleep efficiency (p = 035) of the PSQI scores were significantly reduced in the MCE group after the 12-week intervention. Regarding physical fitness, the flexibility of the MCE group improved significantly after the intervention (p = 028), yet, no significant change was observed in the control group. Additionally, the muscular strength of the control group declined significantly after the 12-week period (p = 034). Our results revealed the effectiveness of the MCE intervention in improving sleep quality and physical fitness in middle-aged adults. Further studies using larger sample sizes, objective measures of sleep quality, different types of exercise training, as well as different populations, are warranted to extend our current findings.

    The status of the physical exercise of college students has been a popular topic in China. This study systematically reviewed the exercise status of Chinese college students and its influencing factors. A keyword and reference search were conducted in the Web of Science, PubMed, Cochrane library, and the China National Knowledge Infrastructure. Additionally, Google Scholar was searched to collect literatures related to physical activity of Chinese university students published in Chinese and English from 1 January 2017 to 30 July 2022. Fifteen studies met the selection criteria and were included in the review. The results show that the main motivation for Chinese college students to exercise is to strengthen their bodies, with running and walking ranking first and ball games ranking second in importance. Most of the college students exercised three times a week, which is the recommended minimum, and most of their workouts were of moderate intensity. Additionally, the workouts lasted for 30 min to 60 min. The main factors affecting college students' exercise are lack of time due to academic pressure, facilities constraints, and lack of professional exercise guidance. In conclusion, the physical fitness of university students should not be underestimated, and this study provides additional reference to promote healthier lifestyles among Chinese college students.

    Although many benefits of urban green space networks have been consistently demonstrated, most of the discussion on space connectivity has concentrated on ecological aspects, such as patch-corridor-matrix connectivity. There are limited systematic studies that have investigated the connectedness between urban parks and people. This study aimed to explore the connectedness among urban parks from the users' perspective by using a systematic literature review. By following the PRISMA protocol and analyzing 54 studies from Scopus and Web of Science between 2017 and 2022, we proposed the concepts of physical connectedness and perceived connectedness. The "physical connectedness" contained the dimensions of road attributes and park attributes, as well as six categories including physical accessibility, street connectivity, the street environment, spatial scale, facilities and amenities, and natural elements. The "perceived connectedness" mainly referred to people's perception of the physical environment. The four categories were perceived accessibility, perceived safety, aesthetics, and Kaplan's perceptual model. Finally, in terms of individual attributes, the impact of sociodemographic factors (age, gender, income, education, and occupation) and the motivation for activity on park connectedness were also taken into account. On the basis of our findings, this study suggested that park connectedness should not only focus on physical connectedness but also perceived connectedness.

    Urbanization may influence physical activity (PA) levels, although little evidence is available for low- and middle- income countries where urbanization is occurring fastest. We evaluated associations between urbanization and total PA, as well as work-, leisure-, home-, and transport-specific PA, for 138,206 adults living in 698 communities across 22 countries within the Prospective Urban and Rural Epidemiology (PURE) study. The 1-week long-form International PA Questionnaire was administered at baseline (2003-2015). We used satellite-derived population density and impervious surface area estimates to quantify baseline urbanization levels for study communities, as well as change measures for 5- and 10-years prior to PA surveys. We used generalized linear mixed effects models to examine associations between urbanization measures and PA levels, controlling for individual, household and community factors. Higher community baseline levels of population density (- 12.4% per IQR, 95% CI - 16.0, - 8.7) and impervious surface area (- 29.2% per IQR, 95% CI - 37.5, - 19.7), as well as the rate of change in 5-year population density (- 17.2% per IQR, 95% CI - 25.7, - 7.7), were associated with lower total PA levels. Important differences in the associations between urbanization and PA were observed between PA domains, country-income levels, urban/rural status, and sex. These findings provide new information on the complex associations between urbanization and PA.

    Fibromyalgia is a highly heterogeneous condition, but the most common symptoms are widespread pain, fatigue, poor sleep, and low mood. Nonpharmacological interventions are recommended as first-line treatment of fibromyalgia. However which interventions are effective for the different symptoms is not well understood. The objective of this study was to assess the efficacy of nonpharmacological interventions on symptoms and disease-specific quality of life. Seven databases were searched from their inception until June 1, 2020. Randomised controlled trials comparing any nonpharmacological intervention to usual care, waiting list, or placebo in people with fibromyalgia aged >16 years were included without language restriction. Fibromyalgia Impact Questionnaire (FIQ) was the primary outcome measure. Standardised mean difference and 95% confidence interval were calculated using random effects model. The risk of bias was evaluated using the modified Cochrane tool. Of the 16,251 studies identified, 167 randomised controlled trials (n = 11,012) assessing 22 nonpharmacological interventions were included. Exercise, psychological treatments, multidisciplinary modality, balneotherapy, and massage improved FIQ. Subgroup analysis of different exercise interventions found that all forms of exercise improved pain (effect size [ES] -0.72 to -0.96) and depression (ES -0.35 to -1.22) except for flexibility exercise. Mind-body and strengthening exercises improved fatigue (ES -0.77 to -1.00), whereas aerobic and strengthening exercises improved sleep (ES -0.74 to -1.33). Psychological treatments including cognitive behavioural therapy and mindfulness improved FIQ, pain, sleep, and depression (ES -0.35 to -0.55) but not fatigue. The findings of this study suggest that nonpharmacological interventions for fibromyalgia should be individualised according to the predominant symptom.

    Portion size selection is an indicator of appetite and within younger adults, is predicted by factors such as expected satiety, liking and motivations to achieve an ideal sensation of fullness (i.e., implicit satiety goals). Currently, there is limited research available on the determinants of portion size selection within older adults. Therefore, the current study aimed to examine the relationship between individual differences in implicit satiety goals, food-related expectations, and portion size selection in older adults. Free-living older adult Singaporeans (N = 115; Nmales = 62; age: M = 66.21 years, SD = 4.78, range = 60-83 years) participated as part of the Brain, Ageing, Microbiome, Muscle, Bone, and Exercise Study (BAMMBE). Participants completed questionnaires on their subjective requirements for experiencing different states of satiety and food-related expectations (i.e., liking, how filling) as well as a computerised portion size selection task. Using a multiple regression, we found that goals to feel comfortably full (B = 3.08, SE = 1.04, t = 2.96, p = .004) and to stop hunger (B = -2.25, SE = 0.82, t = -2.75, p = .007) significantly predicted larger portion size selection (R2 = 0.24, F(4,87) = 6.74, p

    INTRODUCTION: The ankles and feet of footballers are the most commonly affected areas by acute and chronic injuries, especially sprains. The durability of changes in motor control for the sprained injury strongly suggests that central motor commands have been reorganized and restructured involving the sensorimotor system. Indirectly, providing strength training improves muscular strength and benefits cardiometabolic health, coordination, sensorimotor, and motor performance. Thus, this study aimed to identify the effects of strengthening exercises on motor control among footballers with sprained ankles.

    MATERIALS AND METHODS: This scoping review selected studies published from January 2002 to November 2022. The articles were searched through PubMed Central, BMJ Journal, Science Direct, and Scopus using "motor control", "ankle sprain" and "strengthening exercise" as the keywords. After finding the articles, the information extracted included author, year of publication, country, objective, type of study, and motor control analysis summary. The literature search strategy used Preferred Reporting Items for Systematic Review and a meta-analysis (PRISMA) where studies that are related to strengthening exercise and motor control were selected.

    RESULTS: From the initial search, 50 articles were found. After processing, only ten articles were further reviewed. The findings demonstrated strengthening exercises provide changes in neurophysiological parameters with motor performance, improved motor control, strength, balance, pain, and functional movement in footballers with sprained ankles.

    CONCLUSION: This review suggests the application of strengthening exercise interventions not only improves motor control, but strength, balance, pain, and functional performance among footballers with sprained ankles.

    INTRODUCTION: Early diagnostic and treatment advances have resulted in prolonged cancer survivorship. Therefore, exercise intervention in survivorship management is essential for enhancing cancer survivors' health-related quality of life (HRQoL).

    OBJECTIVE: The systematic review and meta-analysis in this study aimed to explore the effect of exercise intervention on health-related quality of life of colorectal cancer survivors.

    METHODS: The current study followed guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA 2020) to identify relevant literature. Comprehensive searches were conducted using EBSCOhost, Web of Science (WOS), Scopus, Science Direct, and PubMed. The inclusion criteria included are randomised control trials studies written in English, with no restrictions for the time of publication that reported the effects of exercise intervention on health-related quality of live among colorectal cancer survivors. Meta-analysis was conducted by pooling the mean and standard deviation of post-intervention scores across randomised control trial studies using a random effects model.

    RESULT: A total of 467 articles were identified but only seven articles were randomised control trials (RCT) (n = 7) with PEDro scores ranging from 6 to 9 showing good internal validity were included in the review. The results of the meta-analysis of pooled data from six RCTs studies on HRQoL showed no significant effect of exercise intervention on HRQoL in the intervention group compared to control group [SMD = 0.25; 95% CI; -0.0, 0.51; Z = 1.88; p = 0.06; I2 = 30.8%].

    CONCLUSION: This meta-analysis provides key insights into the effect of exercise on the health-related quality of life (HRQoL) of colorectal cancer (CRC) survivors. Therefore, more experimental studies should be carried out with rigorous methodology to evaluate the effectiveness of exercise interventions before it is recommended as a routine activity in post-treatment management for CRC survivors.

    Planning interventions such as action planning (AP) and coping planning (CP) have been recognized as influential strategies in promoting physical activity (PA), but mixed results of existing evidence have been observed. This study aims to perform a systematical meta-analysis to evaluate the efficacy of planning interventions for improving PA in the general population. Eight databases, including Medline, Embase, PsycINFO, Cochrane Library, Web of Science, ProQuest, CNKI, and Wanfang Data, were searched to locate relevant randomized controlled trials (RCTs) from their inception to 31 December 2021. In total, 41 trials with 5439 samples were included in this systematic review, and 35 trials were used in our meta-analysis. The results showed that PA was better promoted in the planned intervention group compared to the control group (SMD = 0.35, 95% CI = 0.25-0.44, I2 = 61.4%). Based on the subgroup analyses, we found that planning strategies were more effective among patients, males, when adopting AP intervention, when using the face-to-face sessions delivery mode, and when reinforcements were conducted during the follow-up. The findings of this study indicate that planning interventions significantly improved PA behavior, and, in some contexts, the effects performed better. Future research needs to be conducted to explore the underlying mechanisms of planning interventions and validate their effects more extensively.

    BACKGROUND: Physical inactivity is a significant public health issue affecting working adults because it can increase the risk of noncommunicable diseases.

    OBJECTIVES: The objective is to determine the outcomes of a multi-component workplace environmental intervention that incorporated physical activity self-regulation (PASR) to promote physical activity (PA) among employees.

    MATERIALS AND METHODS: This was a 6-month intervention with a two-group, parallel, quasi-experimental study. A total of 11 workplaces were randomly assigned to intervention group (IG) or control group (CG) using a 1:1 allocation ratio. In each group, 84 eligible participants were recruited. The IG was exposed to the organizational support and the PA support components throughout the study. The PASR Scale, International PA Questionnaire, and pedometer were used to measure the outcome at the baseline, 3rd-month, and 6th-month follow-ups, respectively. The repeated measures-analysis of variance analysis was used to determine the changes in the PASR skills, MET-min/week, and step/week over time.

    RESULTS: The IG had 75 participants (51 females and 24 males) and the CG had 73 participants (52 females and 21 males) at the 6th-month follow-up. Despite there was no statistically significant difference in the outcomes between groups over time, the IG showed significant improvements in total PASR (ηp2 = 0.021), goal setting (ηp2 = 0.024), total MET-min/week (ηp2 = 0.031), housework-related PA (ηp2 = 0.101), and step/week (ηp2 = 0.827) throughout this intervention.

    CONCLUSION: This intervention was found to be effective in improving the PASR skills, MET-min/week, and step/week of IG participants. Meanwhile, because some effect sizes were small, these findings should be interpreted with caution.

    Personalized nutrition is an approach that tailors nutrition advice to individuals based on an individual's genetic information. Despite interest among scholars, the impact of this approach on lifestyle habits and health has not been adequately explored. Hence, a systematic review of randomized trials reporting on the effects of personalized nutrition on dietary, physical activity, and health outcomes was conducted. A systematic search of seven electronic databases and a manual search resulted in identifying nine relevant trials. Cochrane's Risk of Bias was used to determine the trials' methodological quality. Although the trials were of moderate to high quality, the findings did not show consistent benefits of personalized nutrition in improving dietary, behavioral, or health outcomes. There was also a lack of evidence from regions other than North America and Europe or among individuals with diseases, affecting the generalizability of the results. Furthermore, the complex relationship between genes, interventions, and outcomes may also have contributed to the scarcity of positive findings. We have suggested several areas for improvement for future trials regarding personalized nutrition.

    College and university students often exhibit insufficient levels of physical activity, which negatively impacts their health, mental well-being, and academic performance. Social capital has emerged as a potential factor in promoting physical activity. This systematic review, conducted in line with PRISMA guidelines, examines the existing literature on the role of social capital in enhancing physical activity among college and university students. A search of the Web of Science, Scopus, SportDiscus, and PsychINFO databases identified 10 studies published by August 1, 2024, involving 2,700 students, primarily from North America and Europe. The overall quality of the included studies was high, with all scoring above 85% on quality assessments. The findings indicate that social capital, particularly strong social networks, support from family and friends, and high levels of social cohesion, is significantly associated with higher levels of physical activity among college and university students. Social capital may facilitate physical activity in group settings through mechanisms such as emotional support, role modeling, and social norms. Despite limitations within the existing research evidence, such as reliance on self-reported data and cross-sectional study designs, this review suggests that social capital holds potential for promoting physical activity in this population. Future research should prioritize the use of objective measurement tools and longitudinal designs to more accurately assess the long-term effects of social capital and explore how these findings can inform effective interventions.

    AIMS: We tested the hypothesis that the known reduction in myocardial functional reserve in preterm-born young adults is an independent predictor of exercise capacity (peak VO2) and heart rate recovery (HRR).

    METHODS AND RESULTS: We recruited 101 normotensive young adults (n = 47 born preterm; 32.8 ± 3.2 weeks' gestation and n = 54 term-born controls). Peak VO2 was determined by cardiopulmonary exercise testing (CPET), and lung function assessed using spirometry. Percentage predicted values were then calculated. HRR was defined as the decrease from peak HR to 1 min (HRR1) and 2 min of recovery (HRR2). Four-chamber echocardiography views were acquired at rest and exercise at 40% and 60% of CPET peak power. Change in left ventricular ejection fraction from rest to each work intensity was calculated (EFΔ40% and EFΔ60%) to estimate myocardial functional reserve. Peak VO2 and per cent of predicted peak VO2 were lower in preterm-born young adults compared with controls (33.6 ± 8.6 vs. 40.1 ± 9.0 mL/kg/min, P = 0.003 and 94% ± 20% vs. 108% ± 25%, P = 0.001). HRR1 was similar between groups. HRR2 decreased less in preterm-born young adults compared with controls (-36 ± 13 vs. -43 ± 11 b.p.m., P = 0.039). In young adults born preterm, but not in controls, EFΔ40% and EFΔ60% correlated with per cent of predicted peak VO2 (r2 = 0.430, P = 0.015 and r2 = 0.345, P = 0.021). Similarly, EFΔ60% correlated with HRR1 and HRR2 only in those born preterm (r2 = 0.611, P = 0.002 and r2 = 0.663, P = 0.001).

    CONCLUSIONS: Impaired myocardial functional reserve underlies reductions in peak VO2 and HRR in young adults born moderately preterm. Peak VO2 and HRR may aid risk stratification and treatment monitoring in this population.

    Many physically active individuals have undertaken intermittent fasting to reduce their daily caloric intake. However, abstaining from meals for a specific length of time may lead to the acute disturbance of highly carbohydrate-dependent exercise performance. The purpose of this study was to observe the effect of 10 days of intermittent fasting on high-intensity type exercises, Wingate anaerobic (WT) and prolonged high-intensity time-to-exhaustion (HIT) cycling test. Twenty participants were randomised into an intermittent fasting (FAS) and a control group (CON). One day after baseline data collection on Day-0 where participants consumed their recommended daily caloric intake (FAS = 2500 ± 143 kcal day-1; CON = 2492 ± 20 kcal day-1) served over a course of five meals, the FAS group consumed only four meals where 40% was restricted by the omission of lunch (FAS = 1500 ± 55 kcal day-1). This diet was then continued for 10 days. Data on exercise performance and other dependent variables were collected on Day-2, -4, -6, -8 and -10. A reduction in WT power in the FAS group was observed on Day-2 (821.74 ± 66.07 W) compared to Day-0 (847.63 ± 95.94 W) with a moderate effect size (p

    We evaluated feasibility of physical activity measurement by accelerometry among older Malay adults living in semi-rural areas in Malaysia. Results showed that 95% of 146 participants (aged [SD] 67.6 [6.4] years) were compliant in wearing the accelerometer for at least five days. Fifteen participants were asked for re-wear the accelerometer because they did not have enough valid days during the first assessment. Participants wore the accelerometer an average of 15.3 hr in a 24-hr day, with 6.5 (1.2) valid wear days. No significant difference in valid wear day and time was found between men and women. Participants who are single provide more valid wear days compared with married participants (p < .05), and participants with higher levels of education provide longer periods of accelerometer wearing hours (p < .01). Eighty-seven percent of participants reported 'no issues' with wearing the meter. This study suggests that accelerometry is a feasible method to assess the physical activity level among older Malay adults living in semi-rural areas.
