Results from the Chinese Taipei (Taiwan) 2022 report card on physical activity for children and youth.

Background: /Objective: In Taiwan, physical inactivity is highly prevalent among children and adolescents. Chinese Taipei (Taiwan) joined the Global Matrix 3.0 in 2018 to share local data on childhood physical activity and related factors with the international community. This study reports the grades for 10 indicators endorsed by the Global Matrix 4.0 and 1 additional indicator. Methods: Local data for school-aged children and adolescents (approximately 5-17 years old) from 2017 to 2022 were used to determine the grades. The data were obtained from online academic databases and websites of government agencies. The highest priority was given to national surveys, followed by studies using nationally representative samples. Results: The data revealed very poor Overall Physical Activity, Organized Sport Participation, and Active Play (F, D-, and F, respectively). Active Transportation, Sedentary Behavior, and Family and Peers were also below average (C-, D+, and D-, respectively). Taiwan's central and local governments have recognized the importance of physical activity by implementing related policy and improving public sports facilities. Accordingly, School and Community and the Built Environment both received a grade of A-, and Government Strategies and Investments received a B+. Physical Fitness received an INC for lack of data. An additional indicator, body mass index, received a grade of B-. Conclusions: Despite great effort by governments and schools, physical activity levels are low and sedentary behavior is prevalent among Taiwanese children and adolescents.

Report card grades on physical activity for children and adolescents from 18 Asian countries: Patterns, trends, gaps, and future recommendations.

Background: Physical inactivity is a persistent and worsening population health concern in Asia. Led by the Active Healthy Kids Global Alliance, Global Matrix (GM) initiative provides an opportunity to explore how regional and cultural differences across 18 Asian countries relate to physical activity (PA) participation among children and adolescents. Objectives: To synthesize evidence from the GM2.0 to GM4.0 (2016-2022) in Asian countries. Methods: Report Card grades on behavioral/individual and sources of influence indicators were reported from 18 Asian countries. Letter grades were converted into numerical values for quantitative analyses. Based on this, cross-sectional and longitudinal analyses were conducted to investigate patterns and trends. Qualitative evidence synthesis was performed based on Report Card grades and published papers to identify gaps and suggest future recommendations. Results: In total, 18 countries provided grades for at least one round of GM, 12 countries provided grades for at least two rounds, and seven countries provided grades for all three GMs. Of possible grades, 72.8%, 69.2%, and 76.9% of the grades were assigned from GM 2.0 to GM 4.0, respectively. In terms of the Report Card grades, there was a slight decrease in behavioral/individual indicators from "D+" in GM 2.0 to "D-" in GM 3.0 but this reverted to "D" in GM 4.0. For the sources of influence, a "C" grade was given in all three rounds of GM. Longitudinal observation of seven Asian countries that provided grades in all three rounds of GM revealed that grades are generally stable for all indicators with some country-specific fluctuations. In future GM initiatives and research, considerations should be made to provide more accurate and rich data and to better understand contextual challenges in evaluating certain indicators such as Active Transportation, Active Play, and Physical Fitness in particular. Further, macro level factors such as socioeconomic/cultural disparities and gender-specific barriers, ideology, or climate change should also be proactively considered in future research as these factors are becoming increasingly relevant to indicators of GM and United Nation's Sustainable Development Goals. Conclusions: Participation from Asian countries in GM has increased over the years, which demonstrates the region's enthusiasm, capacity, and support for global PA promotion efforts. The efforts to promote a physically active lifestyle among children and adolescents should be a collective interest and priority of the Asia region based on the gaps identified in this paper.

Thirty minutes of moderate-intensity downhill or level running has no effect on postprandial lipemia: A randomized controlled trial.

Elevated postprandial triglyceride (TG) concentrations are linked to a relatively high risk of cardiovascular disease. Eccentric endurance exercise, such as downhill walking and running, can provide metabolic benefits similar to concentric exercise. However, whether eccentric exercise affects postprandial lipemia remains unknown. Nine healthy young men performed level running (trial) or downhill running (DR trial, -15% slope) at 60% [INSIDE:1]O2max or rest (CON trial) for 30 min in a randomized crossover design. The participants were fed a high-fat meal the next day. Blood and expired gas samples were collected before and 0.5, 1, 2, 3, 4, 5, and 6 h after the meal. Muscle soreness was measured using a visual analog scale. The DR trial induced mild muscle damage. During the 6-h postprandial period, serum TG concentrations and area under the curve (AUC) were similar across the three trials. The DR trial had a significantly higher AUC of nonesterified fatty acid concentrations and a significantly lower AUC of glucose concentrations than the CON trial. The results suggested that neither moderate-intensity DR nor running a level surface had a significant effect on lipemia after a high-fat meal. However, DR improved the postprandial glycemic response.

Gender differences on laugh-related traits: A cross-sectional study.

People have different responses to being laughed at, including fear of being laughed at, joy from being laughed at and joy from hearing others laugh. Previous studies have indicated that men have a higher tendency of laughing at others, but there were no gender differences on terms of the other two responses. Socioemotional selectivity theory indicates that individuals pay less attention to negative stimuli as they get older. It is worth investigating whether the gender differences of gelotophobia and gelotophilia occur in certain developmental stages. The present study is a cross-sectional study, with a sample size of 1247 participants; we collected information regarding laugh-related traits among participants 11-66 years old, and we particularly focused on the moderation effect of age on gender differences on gelotophobia, gelotophilia and katagelasticism. The results showed that men had a stronger tendency for laughing at others, but there were no significant gender differences on terms of gelotophobia and gelotophilia; age not only moderated the relationship between gender and gelotophobia but also the relationship between gender and katagelasticism. Male adolescents had higher incidences of gelotophobia and katagelasticism than female adolescents, but this finding was not consistent in the middle adulthood sample. The present study found age to be a moderator between gender and laugh-related traits, and it indicated the influence of age on the fear of being laughed at during early adolescence, but there was no gender difference with respect to katagelasticism in middle adulthood.

Parent-child attachment as a mediator of the relationship between parenting style and gelotophobia among adolescents.

Fear of being laughed at and family interaction are highly related. Parental over-control and over-protection influence children's excessive anxiety over being laughed at. Conversely, parental attachment is an important index of the parent-child relationship and is closely correlated to children's gelotophobia. However, is it the style of parenting or the outcome of parenting (i.e. attachment) that influences a child's gelotophobia? To answer this question, the present study analysed the relationships between gelotophobia, perceived parenting of children and parent-child attachment, as well as the mediating role of attachment between parenting and children's gelotophobia, using a sample of 373 high-school students. The results show that being highly communicative and close attachment completely weakened the negative correlation between warm, caring parenting and the child's gelotophobia; moreover, being highly communicative and close attachment, together with over-protective and over-controlling parenting, influence children's gelotophobia. In sum, this study indicates that parent-child attachment has a direct and indirect influence on perceived parental care and protection and children's fear of being laughed at.

Results from the Chinese Taipei (Taiwan) 2018 Report Card on physical activity for children and youth.

BACKGROUND/OBJECTIVE: Taiwan is facing a high prevalence of physical inactivity in children and adolescents, which has led to rising obesity and morbidity levels in young people. Chinese Taipei (Taiwan) joined the Global Matrix 3.0 to share the local information on childhood physical activity and related factors with the international community. This study reports the grades for 10 indicators endorsed by the Global Matrix 3.0. METHODS: The local data for school-aged children and youth (∼5-17 year-olds) from 2010 to 2018 were used to determine the grades. The highest priority was given to the national survey data released by the government or academic institutions, followed by academic publications using nationally representative samples. Government or academic publications relying on only regional samples were excluded. RESULTS: The data showed very poor Overall Physical Activity and Organized Sport Participation (F and D-, respectively). The grades for Active Transportation and Sedentary Behavior were C-. Low physical activity levels and high screen time may have led to sub-optimal Physical Fitness levels (B-). The central and local governments have recognized the importance of physical activity by creating related policy and improving facilities. Therefore, School, Community and the Built Environment, and Government Strategies and Investments all received the grade of B+. Active Play and Family and Peers received INC for a lack of sufficient data. CONCLUSIONS: Despite great effort by the governments and schools, physical activity and fitness levels are low while sedentary behavior is prevalent in Taiwanese children and youth.

A Single Bout of Exercise Reduces Postprandial Lipemia but Has No Delayed Effect on Hemorheological Variables.

High plasma triglyceride (TG) concentration in fasting state could cause hemorheological abnormality, thus increasing the incidence of metabolic diseases. Exercise has been reported to effectively reduce postprandial TG response. This study aimed to investigate whether a single bout of pre-prandial exercise can affect lipemia and hemorheological variables after a high-fat meal. Nine healthy young male subjects completed two experimental trials. The subjects walked for 1 h at 50% maximal oxygen uptake (V̇O2max) (the exercise, EX trial), or rested (the control, CON trial). In the next morning, the subjects consumed a high-fat meal, and the postprandial lipemia and hemorheological responses were monitored for 6 h. The results showed that postprandial plasma TG concentrations were significantly lower in the EX trial compared to the CON trial. The postprandial low-density lipoproteins (LDL) concentration declined in the first 2 h and then gradually returned to the baseline level in both trials. The postprandial blood viscosity also decreased in the CON trial. There was no significant difference in postprandial blood viscosity, red blood cell (RBC) deformation index and aggregation degree between the trials. There was no significant correlation between plasma TG concentration and blood viscosity. In conclusion, brisk walking effectively reduced postprandial TG concentration, but has no significant impact on postprandial blood viscosity, RBC deformation index and RBC aggregation index.

The Effect of Functional Movement Training After Anterior Cruciate Ligament Reconstruction: A Randomized Controlled Trial.

OBJECTIVES: To evaluate the effect of functional movement screen (FMS)-based functional exercise in patients after anterior cruciate ligament reconstruction (ACLR). DESIGN: Randomized, controlled, single-blind trial. SETTING: Institutional, single center. PATIENTS: A total of 38 patients who underwent ACLR were recruited and randomly assigned to group 1 (n = 19) or group 2 (n = 19). INTERVENTIONS: Both groups received 6-month routine rehabilitation immediately after surgery. From the postoperative fourth to sixth month, group 1 received FMS-based functional exercise plus routine rehabilitation and group 2 received routine rehabilitation only. The FMS-based functional exercise was individualized and customized functional corrective exercise, which was designed based on the 3-month postoperative FMS results. The frequency of rehabilitation was 1 hour per session, twice a week, for a total duration of 6 months. MAIN OUTCOME MEASURES: At 3 and 6 months postoperatively, patients were evaluated by FMS scoring, Lysholm Knee Score, and International Knee Documentation Committee 2000 Score. RESULTS: After the intervention, both groups had significantly increased FMS, Lysholm Knee Score, and International Knee Documentation Committee 2000 score. Group 1 had significantly greater changes in FMS (median: 4 vs 3, P < .001), Lysholm Knee Score (median: 24 vs 16, P = .001), and International Knee Documentation Committee 2000 Score (median: 22 vs 8, P < .001) than group 2. CONCLUSION: The application of FMS-based functional exercise to patients after ACLR resulted in significant improvement in knee function and movements. The authors suggested integrating FMS evaluation and FMS-based training into routine post-ACLR rehabilitation programs.

Normative data for Chinese compound remote associate problems.

The Remote Associates Test (RAT) is a well-known measure of creativity, with each item on the RAT is composed of three unrelated stimulus words. The participant's task is to find an answer in the form of a word that could combine with each of the stimulus words, thus forming three new actual nouns. Researchers have modified the RAT to develop compound remote associate problems that emphasize combining vocabulary to form compound words. In the field of creativity research for Mandarin speakers, the Chinese RAT has been widely applied for over 10 years. The original RAT, compound remote associate problems, and Chinese RAT have various common advantages, such as being convenient to use and having objective scoring; additionally, the development of items for certain tests is easy and satisfies the requirements of psychological assessments in terms of the quantity of items. Currently, many language editions of the RAT and compound remote associate problems already exist. In particular, the English and Italian versions of these tests already have derived normative data. Because approximately 20% of the world's population are native Mandarin speakers, and because increasing numbers of people are choosing Mandarin as a second language, the need to increase Mandarin-language resources is growing; however, normative data for the Chinese RAT still do not exist. To address this issue, in the present study we developed Chinese compound remote associate problems and analyzed the passing rates by items, problem solving times, and various normative data, using the responses of 253 subjects in three experiments.

Estimation of potential gain in quality of life from early detection of cervical cancer.

OBJECTIVE: To estimate the lifetime gain in the health-related quality of life (HRQOL) from early detection of cervical cancer. METHODS: A consecutive, cross-sectional sample of 421 patients with cervical cancer was administered the World Health Organization Quality of Life-brief version questionnaires. A nationwide sample of 22,543 patients with invasive cervical cancer (ICC) was collected from the national cancer registry for estimation of lifetime survival function from 1998 to 2007, which was further multiplied by the ratio of HRQOL score functions for patients with ICC and patients with carcinoma in situ (CIS), and summed up over lifetime to obtain expected relative-quality-adjusted survival. The difference between lifetime survival and the expected relative-quality-adjusted survival gives the expected total dissatisfied time during the life course. RESULTS: In comparison with patients with CIS postconization, patients with ICC showed consistently lower scores in the physical and psychological domains and that of sexual life after adjustment for other risk factors. The expected years of life lost for an invasive cancer was 6.48 years using the general population as the reference cohort, while the durations of equivalent to living with a very dissatisfied HRQOL were 1.71 and 0.25 for the physical and psychological domains, respectively, and 1.47 years for sexual life. Validation of the extrapolation method based on a subcohort followed from the 6th to the 13th year shows a relative bias of 0.4%. Sensitivity analysis with 37,000 CIS cases as the reference cohort yields a similar result. CONCLUSIONS: Early detection of cervical cancer not only avoids premature mortality but also prevents long-term living under lower HRQOL scores, including sexual life.

Energy replacement using glucose does not increase postprandial lipemia after moderate intensity exercise.

BACKGROUND: Aerobic exercise can decrease postprandial triglyceride (TG) concentrations but the relationship between exercise-induced energy deficits and postprandial lipemia is still unclear. The aim of the present study was to examine the effect of a single bout of aerobic exercise, with and without energy replacement, on postprandial lipemia and on peripheral blood mononuclear cell (PBMC) mRNA expression of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) receptors and 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR). METHODS: Nine healthy male humans completed three two-day trials in a random order. On day 1, volunteers rested (CON), completed 60 minutes of treadmill walking at 50% of VO2peak (EX) or completed the same bout of walking but with the energy replaced afterwards with a glucose solution (EXG). On day 2, volunteers rested and consumed a high fat test meal in the morning. RESULTS: Total and incremental TG AUC were significantly lower on the EXG (P < 0.05) and EX (P < 0.05) trials than the CON trial with no difference between the two exercise trials. No significant difference was observed in VLDL or LDL receptor mRNA expression among the trials (P > 0.05). CONCLUSIONS: In conclusion, energy replacement by glucose did not affect the decrease in postprandial TG concentrations observed after moderate intensity exercise and exercise does not affect changes in PBMC HMGCR, VLDL and LDL receptor mRNA expression.

Effects of pre-exercise high and low glycaemic index meals on substrate metabolism and appetite in middle-aged women.

Few studies have examined the influence of pre-exercise meals with different glycaemic indices (GIs) on substrate oxidation and non-homeostatic appetite (i.e. food reward) in adults of various ages and ethnicities. We aimed to examine the effects of pre-exercise high and low GI meals on substrate oxidation and food reward in middle-aged Japanese women. This randomised crossover trial included fifteen middle-aged women (aged 40⋅9 ± 6⋅5 years, mean ± sd). The participants consumed a high or low GI breakfast at 09.00 and rested until 11.00. Thereafter, participants performed a 60-min walk at 50 % of their estimated maximum oxygen uptake (11.00-12.00) and rested until 13.00. Expired gas samples were collected every 30 min prior to walking, and samples were collected continuously throughout the walking and post-walking periods. Blood samples and subjective appetite ratings were collected every 30 min, except during walking. The Leeds Food Preference Questionnaire in Japanese (LFPQ-J) was used to assess food reward at 09.00, 10.00, and 13.00 h. The cumulative fat oxidation during exercise was higher in the low GI trial than in the high GI trial (P = 0⋅03). The cumulative carbohydrate oxidation during walking was lower in the low GI trial than in the high GI trial (P = 0⋅01). Trial-by-time interactions were not found for any food-reward parameters between trials. Low GI meals elicited enhanced fat oxidation during a subsequent 60-min walk in middle-aged women. However, meals with different GIs did not affect food reward evaluated over time in the present study.

Oral hydroxycitrate supplementation enhances glycogen synthesis in exercised human skeletal muscle.

Glycogen stored in skeletal muscle is the main fuel for endurance exercise. The present study examined the effects of oral hydroxycitrate (HCA) supplementation on post-meal glycogen synthesis in exercised human skeletal muscle. Eight healthy male volunteers (aged 22·0 (se 0·3) years) completed a 60-min cycling exercise at 70-75 % VO2max and received HCA or placebo in a crossover design repeated after a 7 d washout period. They consumed 500 mg HCA or placebo with a high-carbohydrate meal (2 g carbohydrate/kg body weight, 80 % carbohydrate, 8 % fat, 12 % protein) for a 3-h post-exercise recovery. Muscle biopsy samples were obtained from vastus lateralis immediately and 3 h after the exercise. We found that HCA supplementation significantly lowered post-meal insulin response with similar glucose level compared to placebo. The rate of glycogen synthesis with the HCA meal was approximately onefold higher than that with the placebo meal. In contrast, GLUT4 protein level after HCA supplementation was significantly decreased below the placebo level, whereas expression of fatty acid translocase (FAT)/CD36 mRNA was significantly increased above the placebo level. Furthermore, HCA supplementation significantly increased energy reliance on fat oxidation, estimated by the gaseous exchange method. However, no differences were found in circulating NEFA and glycerol levels with the HCA meal compared with the placebo meal. The present study reports the first evidence that HCA supplementation enhanced glycogen synthesis rate in exercised human skeletal muscle and improved post-meal insulin sensitivity.

Observation of quantum confinement effect on ZnO embedded mesoporous silica.

Nonionic surfactant as liquid organic template and tetraethoxysilane as silica precursor were used for the synthesis of mesoporous silica with ordered arrangement of nanopores (diameters are about 1-6 nm). The synthesized mesoporous silica was used as the template for the synthesis of ZnO nanoparticles using zinc acetylacetonate as ZnO precursor. The as synthesized ZnO incorporated in the mesoporous silica nanocomposite were analyzed using X-ray diffraction, TEM and Photoluminescent spectrum. ZnO introduction has no extensive influence on the mesoporous structure of silica. Quantum confinement effects are observed in the case of ZnO nanoparticles embedded in mesoporous silica. The particle size of ZnO is about 3.2 nm. The band gap is broadening to 3.47 eV.

Measuring Conceptual Associations via the Development of the Chinese Visual Remote Associates Test.

Multiple versions of the Chinese Remote Associates Test (CRAT) have been developed. Thus far, all CRATs have employed verbal stimuli; other forms of stimuli have not yet been used. In this context, the present study compiled a Chinese Visual Remote Associates Test (CVRAT) that conforms to the Chinese language and culture based on a picture naming database. The developed CVRAT has two versions, CVRAT-A and CVRAT-B, each comprising 20 test questions. A typical CVRAT question consists of three stimuli pictures, requiring respondents to propose a target word that is semantically associated with all the pictures. When compiling the CVRAT, this study first selected target words, sifted through stimuli words and corresponding pictures, and analyzed pilot test questions. After compilation, their reliability and validity were examined. The results showed that the CVRAT had moderate internal consistency reliability, good criterion-related validity for the Chinese Word Remote Associates Test (CWRAT), Chinese Radical Remote Associates Test (CRRAT), Chinese Compound Remote Associates Test (CCRAT), insight problem-solving, as well as acceptable discriminant validity for fluency, flexibility, and originality of a divergent thinking test. In other words, CVRAT can effectively measure remote associative capability and provides a figural creativity test that facilitates the understanding of different kinds of remote associations.

Walking Exercise Reduces Postprandial Lipemia but Does Not Influence Postprandial Hemorheological Properties and Oxidative Stress.

A higher postprandial triglycerides response and hemorheological abnormalities may increase the incidence of metabolic disorders and negatively interfere with the aging process. A single session of preprandial endurance exercise was found to be effective in reducing triglyceride levels after a high-fat diet. However, whether the exercise-induced reduction in postprandial triglyceride levels influences hemorheological indicators remains unknown. This study aims to investigate the effects of postprandial lipemia on hemorheological properties and oxidative stress. Eight healthy young male participants completed two experimental trials. On day 1, the participants were randomly assigned to walk for 1 h at 50% VO2max (EE trial) or rest (CON trial). On day 2, participants rested and consumed a high-fat meal in the morning. Results: The postprandial area under the curve (AUC) of plasma TG concentration was significantly lower in EE compared to CON (EE: 9.2 ± 1.9; CON: 10.9 ± 1.7 mmol/L·h−1; p = 0.013; Cohen's d = 0.036). No significant difference was observed in hemorheological properties and MDA (p > 0.05). Endurance exercise effectively decreased postprandial TG concentration but did not influence the postprandial hemorheological properties and oxidative stress indicators.

Development and validation of interactive creativity task platform.

Co-creativity focuses on how individuals produce innovative ideas together. As few studies have explored co-creativity using standardized tests, it is difficult to effectively assess the individual's creativity performance within a group. Therefore, this study aims to develop a platform that allows two individuals to answer creativity tests simultaneously. This platform includes two divergent thinking tasks, the Straw Alternative Uses Test and Bottle Alternative Uses Test, and Chinese Radical Remote Associates Test A and B, which were used to evaluate their open-and closed-ended creative problem-solving performance. This platform has two modes: single-player mode and paired-player mode. Responses from 497 adults were collected, based on which the fluency, flexibility, and originality of divergent thinking were measured. This study also developed a computer scoring technique that can automatically calculate the scores on these creativity tests. The results showed that divergent thinking scores from computer-based calculation and manual scoring were highly positively correlated, suggesting that the scores on a divergent thinking task can be calculated through a system that avoids time-consuming, uneconomical manual scoring. Overall, the two types of tests on this platform showed considerable internal consistency reliability and criterion-related validity. This advanced application facilitates the collection of empirical evidence about co-creativity.

Visual-Spatial and Verbal Remote Association: An fMRI Study.

Although idea connections at verbal and conceptual levels have been explored by remote associates tests, the visual-spatial level is much less researched. This study investigated the visual-spatial ability via Chinese Radical Remote Associates Test (CRRAT), wherein respondents consider the positions of the stimulus and target Chinese radicals. Chinese Compound Remote Associates Test (CCRAT) questions also feature stimuli of a single Chinese character; therefore, it was adopted for comparison to distinguish the roles played by verbal and visual-spatial associations in a remote associative process. Thirty-six adults responded to CRRAT and CCRAT; their brain activities were analyzed. Upon excluding the influence of age, verbal comprehension, and working memory, it was found that the caudate, posterior cingulate cortex, postcentral gyrus, and medial frontal gyrus were activated when the respondents answered CCRAT, but only the caudate showed significant activation when they answered CRRAT. The Chinese radical remote association minus the Chinese compound remote association showed that the middle frontal gyrus, inferior parietal lobule, and precuneus demonstrated significant activation. Therefore, this study demonstrated differences in brain mechanisms between visual-spatial and verbal remote associations.

A Systematic Review of MRI Neuroimaging for Education Research.

This study aims to disclose how the magnetic resonance imaging (MRI) neuroimaging approach has been applied in education studies, and what kind of learning themes has been investigated in the reviewed MRI neuroimaging research. Based on the keywords "brain or neuroimaging or neuroscience" and "MRI or diffusion tensor imaging (DTI) or white matter or gray matter or resting-state," a total of 25 papers were selected from the subject areas "Educational Psychology" and "Education and Educational Research" from the Web of Science and Scopus from 2000 to 2019. Content analysis showed that MRI neuroimaging and learning were studied under the following three major topics and nine subtopics: cognitive function (language, creativity, music, physical activity), science education (mathematical learning, biology learning, physics learning), and brain development (parenting, personality development). As for the type of MRI neuroimaging research, the most frequently used approaches were functional MRI, followed by structural MRI and DTI, although the choice of approach was often motivated by the specific research question. Research development trends show that the neural plasticity theme has become more prominent recently. This study concludes that in educational research, the MRI neuroimaging approach provides objective and empirical evidence to connect learning processes, outcomes, and brain mechanisms.

The interactive effect of exercise and immunosuppressant cyclosporin A on immune function in mice.

Cyclosporin A (CsA) is an effective immunosuppressive agent and exerts its actions by interfering with the activation of T cells. There is growing evidence that regular exercise improves immune function. However, the effects of exercise on immune functions in patients taking CsA are unclear. Here, we examine the interactive effects of CsA administration and regular exercise on immune function in mice. Forty-eight BALB/c mice were randomly assigned to one of six groups with eight mice per group: 0-Ex (no CsA/no exercise), 0 + Ex (no CsA + exercise), 10-Ex (10 mg kg(-1) day(-1) CsA/no exercise), 10 + Ex (10 mg kg(-1) day(-1) CsA + exercise), 20-Ex (20 mg kg(-1) day(-1) CsA/no exercise), and 20 + Ex (20 mg kg(-1) day(-1) CsA + exercise). The three exercise groups were trained for 8 weeks, three times a week, at approximately 75% maximum oxygen uptake (VO(2max)). Nitric oxide and interferon-gamma secretions by mitogen-activated macrophages and spleen cells, respectively, were higher in exercise groups than in non-exercise groups receiving the same doses of CsA. The results of this study indicate that regular exercise may enhance Type I helper T cell functions in mice receiving 10 or 20 mg kg(-1) day(-1) CsA. Our results demonstrate that moderate regular exercise modulates the immune function of CsA-treated mice. However, whether this exercise-induced immunomodulatory effect is beneficial or detrimental to CsA-treated patients needs to be clarified.
