UNASSIGNED: There is evidence showing the effect of hypocaloric diet and increasing physical activity on weight loss. However, the effect of these factors on body composition and functional capacity remains unclear. Also, it is not clear which type of exercise (aerobic, resistance) has effective health benefits for men who are overweight. The aim of this study is to investigate whether a 12-week combined exercise or walking intervention combined with a hypocaloric diet provides improvements in body composition and functional capacity of men who are overweight compared to those who do not exercise.
UNASSIGNED: 60 healthy adult men who are overweight were randomized and divided into 3 groups: 1: Hypocaloric Diet + Combined Exercise; 2: Hypocaloric Diet + Walking; 3: Hypocaloric Diet. The exercise groups were trained for 12 wk, 3 days a week and 60 min (60 min\\3 days\\12 wk). Body composition was determined with Bioelectrical Impedance Analysis (BIA) device, strength parameters with MicroFet 2, functional capacity with 6-min walking test.
UNASSIGNED: Improvement was observed in all groups at the end of 12 wk. The greatest improvement was in the combined exercise group. While the values of the combined exercise group increased in Skeletal Muscle Mass, there was a decline in the walking and non-exercising group. Basal Metabolism was maintained in combined exercise, but a decrease occurred in the non-exercising group. Muscle force increased in combined exercise; however, it was maintained in the legs in the walking group. Cardiorespiratory fitness was at best level in walking group, but there was no difference between combined exercise.
UNASSIGNED: As a result, a hypocaloric diet without an exercise prescription is sufficient to lose weight in the short term (12 wk) at a certain level. But exercise is more important for body composition, weight management and functional capacity. Long-term and in-depth studies should be conducted to interpret the results better.

The correctional training program (CTP), composed of three stages, includes a 14 week in-person component that Correctional Officer Recruits (CORs) must complete prior to their employment as a federal Correctional Officer (CO) for Correctional Service Canada (CSC). The CTP prepares recruits for a plethora of CO responsibilities, some dependent on physical fitness, such as responding to codes being called, physical altercations, or violent situations. Unlike other public safety positions (e.g. policing, border services, or coast guard) CSC does not require occupational fitness testing. In the current article, we use data from a multiyear longitudinal study of federal COs from across Canada to unpack how CORs manage physical fitness expectations at CTP; CSCs\' expectations of COR physical fitness; and outline what types of physical fitness (e.g. weightlifting, cardiovascular, self-defence) are taught, thus valued most, during CTP. We situate the voices of CORs regarding physical fitness within the broader \"body\" literature and discuss policy recommendations tied to physical fitness, specifically COs\' interest in reinstating pre-employment physical fitness screening.

OBJECTIVE: To investigate the physical fitness level and health behavior status of preschool children in China, explore the relationship between physical fitness and health behavior, and further reveal the main factors affecting health behavior, to provide a reference for improving the physical fitness level of preschool children and maintaining healthy behavior.
METHODS: A total of 755 preschool children (394 boys and 361 girls, aged 4.52 ± 1.11 years) were selected from Chongqing and Liupanshui in China by cluster random sampling method for questionnaire survey and physical monitoring, and SPSS21.0 software was used to process and analyze the data.
RESULTS: (1) Heart rate (p = 0.015), protein content (p < 0.001), and time spent on the balance beam (p < 0.001) were significantly lower in boys than in girls, while BMI (p = 0.012), muscle mass (p < 0.001), and distance of standing long jump (p < 0.001) were significantly higher in boys than in girls. Meanwhile, systolic blood pressure (p = 0.004) and diastolic blood pressure (p = 0.001) of rural children were significantly higher than those of urban children, while BMI (p < 0.001) and sitting forward flexion (p = 0.019) were significantly lower than those of urban children. (2) The light-intensity physical activity (LPA) and moderate to vigorous physical activity (MVPA) of boys were significantly higher than that of girls (p < 0.001), and the MVPA of urban children was significantly higher than that of rural children (p = 0.001), and the former participated in sports classes more frequently (p < 0.001). (3) There was a significant correlation between physical activity (PA) and physical fitness indicators of preschoolers. Participating in sports interest classes was only significantly correlated with systolic blood pressure (r = 0.08) and sitting forward flexion (r = 0.09). (4) The PA level of preschool children was related to gender, household registration, kindergarten nature, age, residence environment, parental support, and participation degree. Participation in sports interest classes was related to gender, the nature of the kindergarten, household registration, age, and parent participation. Daily screen time was related to household registration, the nature of the kindergarten, the environment of residence, and the value perception of parents.
CONCLUSIONS: There were different degrees of correlation between preschool children\'s physical fitness and health behaviors, and children\'s health behaviors were closely related to gender, environment, parents, and other factors. Therefore, how to increase the protective factors of children\'s health behaviors and controlling the risk factors may be crucial to promoting the development of good health behaviors and improving the physical fitness of preschool children.

UNASSIGNED: To investigate the effects of 12-week weight-bearing dance aerobics (WBDA) on muscle morphology, strength and functional fitness in older women.
UNASSIGNED: This controlled study recruited 37 female participants (66.31y ± 3.83) and divided them into intervention and control groups according to willingness. The intervention group received 90-min WBDA thrice a week for 12 weeks, while the control group maintained normal activities. The groups were then compared by measuring muscle thickness, fiber length and pennation angle by ultrasound, muscle strength using an isokinetic multi-joint module and functional fitness, such as 2-min step test, 30-s chair stand, chair sit-and-reach, TUG and single-legged closed-eyed standing test. The morphology, strength, and functional fitness were compared using ANCOVA or Mann-Whitney U test to study the effects of 12 weeks WBDA.
UNASSIGNED: Among all recruited participants, 33 completed all tests. After 12 weeks, the thickness of the vastus intermedius (F = 17.85, P < 0.01) and quadriceps (F = 15.62, P < 0.01) was significantly increased in the intervention group compared to the control group, along with a significant increase in the torque/weight of the knee flexor muscles (F = 4.47, P = 0.04). Similarly, the intervention group revealed a significant improvement in the single-legged closed-eyed standing test (z = -2.16, P = 0.03) compared to the control group.
UNASSIGNED: The study concluded that compared to the non-exercising control group, 12-week WBDA was shown to thicken vastus intermedius, increase muscle strength, and improve physical function in older women. In addition, this study provides a reference exercise program for older women.

The present study aimed to identify parameters that best discriminate between high-level and scholar-level players for the Brazilian 13-14-year-old girl\'s handball and propose a mathematical model to identify sports talent for handball. The sample was made up of all available handball players comprising these two groups: 100 girls who participated in the high-level handball championship in Brazil and 53 girls (age 13-14 years) as finalists of the school-level games in one region of Brazil. We assess the anthropometric profile, maturity offset, physical fitness, and technical skills for handball. To propose the equation, the Discriminant Function Analysis method was used. The discriminant function was significant (p ≤ .05), had a good canonical correlation (0.590), and still had an average Wilk Lambda (0.652). The variables considered in the talent identification model included: 1. flexibility, 2. abdominal strength, 3. lower limbs muscle power, 4. agility, 5. defensive movement and 6. slalom with ball. The values from the equation for identifying school-age athletes with high motor skills and performance for handball can be classified by a cutoff point (Y = 0.192). The results showed that the mathematical-model obtained was able to select school-age athletes with high motor skills for handball, and with the profile for participation in high-level championships.

BACKGROUND: Taiwan is an aging society, and the number of people with dementia is rapidly increasing. Due to a decline in cognitive and physical function, older adults with dementia not only gradually lose the ability to complete daily living tasks on their own, but are also at a higher risk of falls and injurious falls. It is important to develop interventions that combine cognitive and exercise training for older adults with dementia to promote or maintain their cognitive and physical functions and reduce their risk of falls. This study aimed to investigate the feasibility and effect of cognitive-based board games and multi-component exercise interventions on cognitive function, physical fitness, and fall risk in older adults with dementia.
METHODS: This was a quasi-experimental study with a single-group pretest and post-test design. The study participants were 41 community-dwelling older adults with mild to moderate dementia. They received cognitive-based board games and multi-component exercise interventions once a week for 12 weeks. The interventions included 1 hour of exercise training and 1 hour of cognitive training. Scores for the Taiwan version of the Montreal Cognitive Assessment (MoCA-T), physical fitness, and the St. Thomas Risk Assessment Tool for Falling Elderly Inpatients (STRATIFY) were measured as outcome indicators at baseline and after the 12-week period.
RESULTS: The overall MoCA-T score increased significantly (effect size = 0.402), with participants with mild dementia showing a greater increase (effect size = 0.522) than those with moderate dementia (effect size = 0.310). Participants\' physical fitness performance improved. Female participants exhibited significant improvements in the 30-second chair stand test (effect size = 0.483) and 8-foot up-and-go test (effect size = 0.437). The fall risk score decreased by 0.05 points, the change was not significant.
CONCLUSIONS: The cognitive-based board game and multi-component exercise interventions used in this study are beneficial for improving cognitive function and physical fitness in older adults with dementia. These interventions are feasible and suitable for promotion among community-dwelling and institution-dwelling older adults with mild cognitive impairment or dementia to delay the decline in cognitive and physical function.

UNASSIGNED: The associations of fundamental motor skills (FMS), health-related physical fitness (e.g., cardiorespiratory fitness, CRF), and moderate-vigorous physical activity (MVPA) have been demonstrated in Western children, but these associations have not yet been validated in a sample of Chinese children. The aims of this study, therefore, were to examine the association between FMS subdomains and MVPA in a sample of Chinese children and to evaluate whether this association is mediated by CRF.
UNASSIGNED: A cross-sectional study consisting of 311 children aged 8-12 years (49.2% girls; mean age = 9.9 years) from Shanghai was conducted. FMS, CRF and MVPA were assessed using the Test of Gross Motor Development-3rd Edition, Progressive Aerobic Cardiovascular Endurance Run and ActiGraph GT3X accelerometers. Preacher & Hayes\'s bootstrap method was used to test the mediating effects of CRF on the association between FMS and MVPA.
UNASSIGNED: CRF fully mediated the association between total FMS and MVPA in girls (indirect effects, b = 0.21, 95% CI [0.07-0.37]), while the mediation was only partial in boys (indirect effects, b = 0.12, 95% CI [0.01-0.26]). CRF fully mediated the association between locomotor skills and MVPA in girls (indirect effects, b = 0.27, 95% CI [0.09- 0.51]), whereas CRF partially mediated the association between object control skills and MVPA in boys (indirect effects, b = 0.15, 95% CI [0.18-0.35]).
UNASSIGNED: In order to better design and implement sex-specific interventions aiming to increase MVPA, it is essential to consider FMS subdomains and CRF alongside the sex differences in the association between them.

BACKGROUND: Children with intellectual disability are less physically active and more sedentary than typically developing peers. To date no studies have tested the feasibility of a school-based walking intervention for children with Intellectual Disability.
METHODS: A clustered randomised controlled trial (cRCT), with an embedded process evaluation, was used to test the feasibility of a school-based walking intervention. Eight schools (n = 161 pupils aged 9-13 years) were randomised into either an intervention arm or an \'exercise as usual\' arm. Measures included physical activity, physical fitness and emotional wellbeing. Baseline and 3-month follow-up data were collected.
RESULTS: The \'Walk Buds\' intervention was found to be acceptable to teaching staff and pupils, with an uptake rate of the walking sessions offered of 84%.
CONCLUSIONS: A number of challenges were experienced, relating to the COVID-19 pandemic, and difficulties collecting accelerometer data. Barriers, facilitators and required changes identified through the mixed methods process evaluation are discussed.

Numerous youth summer programs focus upon physical fitness, nutritional health, psychological well-being, or education. Few, however, have integrated all of these elements into a single program. The Translational Health in Nutrition and Kinesiology (THINK) program provides an integrative nutrition and exercise science curriculum that is interfaced with social emotional learning (SEL) and STEM education to enhance healthy behaviors in youth. The purpose of this study was to determine whether the THINK program could improve physical fitness, nutrition habits, SEL, and STEM education in a 6-week summer program covering a 3-year period. Participants from South Miami were enrolled in THINK (n = 108, 58 males, 50 females, 12.03 + 0.56 years). Physical fitness assessments, the Positive Youth Development Inventory (PYDI), the Students\' Attitude Towards STEM Survey, and the Adolescent Food Habits Checklist (ADFH) were recorded at baseline and post-testing. Means and standard error values were evaluated for all dependent variables. Paired samples t-tests (SPSS version 27) were used to determine changes. Improvements in cardiorespiratory fitness (p < 0.001), power (p < 0.006), flexibility (p < 0.001), agility (p < 0.001), muscular endurance (p < 0.001), lean body mass (p < 0.001), ADFH (p < 0.001), and PYDI (p = 0.038) were found. An integrative summer fitness program can result in improvements in physical fitness, nutrition habits, and SEL in as little as six weeks.

Background: Heart failure (HF) patients experience reduced functional fitness level (determining the performance of routine, daily activities) and diminished exercise capacity (linked to more effortful activities). Aim: The aim of the study is to assess this relationship using functional fitness tests compared to peak VO2 and VE/VCO2 slope in the context of exercise capacity and ventilatory response to exercise. Methods: A total of 382 men with stable HFrEF (age: 61 ± 10, NYHA class I/II/III/IV: 16/50/32/2%, LVEF: 30.5 ± 8.3%) underwent cardiopulmonary exercise testing (CPX) and a Senior Fitness Test (SFT). Afterwards, the patients were divided according to the 2capacity with peak VO2 ≥ 18 mL/kg/min, those with higher or lower ventilatory responses (VE/VCO2 slope ≥ 35 vs. <35) to the exercise were compared. Results: Patients who covered shorter distances in the 6 min walking test showed worse results in the functional tests (\'stand up and go\', \'chair stand\' and \'arm curl\') and CPX (lower peak VO2, shorter exercise time and higher VE/VCO2 slope). Subjects classified into Class D demonstrated the worst results in all elements of SFT; those in Class A demonstrated the best results. Significant differences that were analogous occurred also between classes B and C. Among the participants who reached peak VO2 ≥ 18 mL/kg/min (n = 170), those with VE/VCO2 slope ≥ 35 were characterized by worse physical fitness as compared to those with VE/VCO2 < 35. Conclusion: Reduced exercise tolerance led to worsening physical function in patients with HFrEF. Moreover, limitations in physical fitness seem to be distinctive for those patients showing excessive ventilatory response to exercise slope VE/VCO2 (≥35). The Senior Fitness Test may be considered as a useful tool for assessing comprehensive functional and clinical status and risk stratification in patients with HFrEF, especially those with extremely low exercise capacity.
