Bangladesh has been facing a significant and growing burden of diabetes mellitus handling in recent decades. In the present study, we investigated whether a daily walking intervention could improve the fasting blood sugar level in newly diagnosed diabetes mellitus participants in rural Bangladesh who were not on medication. A rural population of 1,045 people in Bangladesh were screened for diabetes mellitus. One hundred fifty-six people, including 87 diabetes mellitus participants, went through a 5-month daily walking program (twice daily, 1.5 km walking each time). In our initial screening, the prevalence of newly diagnosed diabetes mellitus cases was 8.5% in the rural population. Mean fasting blood sugar level in these new diabetes mellitus cases was 10.0 ± 0.33 mmol/L. After five months of exercise, both the fasting blood sugar and 2h OGTT sugar levels were significantly improved, and no DM (diabetes mellitus) cases were on medication. The current research findings show that a walking program can be a potential lifestyle intervention to combat the diabetes mellitus epidemic in a poor rural context in Bangladesh.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46624985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analyses included 80 Japanese upper elementary students and 44 Japanese junior high students. Consistency of the classification of achieving/not achieving the PA recommendation between the two methods (PACE+ and ActiGraph accelerometry) was assessed by calculating percentage agreement rate, sensitivity, and specificity. Spearman rank correlation (ρ) was applied to assess the correlation between the two methods. The percentage agreement in upper elementary students and junior high students was 83.8% and 65.9%, respectively. While the sensitivity and specificity of the scale in assessing the compliance of upper elementary students with PA recommendation were 8.3% and 97.1%, respectively, and for junior high school students 42.9% and 76.7%, respectively. The correlation coefficients between PACE+ and accelerometry for elementary and junior high school students were 0.13 and 0.50, respectively. The validity of PACE+ among Japanese adolescents was confirmed similarly to previous studies conducted in other countries. However, it should be viewed with caution that PACE+ may underestimate the proportion of children achieving PA recommendations.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41537008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RT model predicts muscle activity, fatigue and recovery, and can be used to predict the mechanical impulses identified in different muscle fiber types. Several resistance training program variables (e.g. load, velocity, number of sets, and duration of rest intervals) were addressed in this study. Experimental data from six subjects were taken under several different training protocols. For the protocols studied, the model precisely predicted the maximum number of repetitions during knee extension resistance exercise (R2 = 0.87). This study demonstrates the applicability of the first simple mathematical model for voluntary dynamic exercise of knee extensor muscles. The developed model calculates the mechanical impulse of fast twitch fiber for the selected protocols. For instance, the model shows high intensity training tends to induce more fast-twitch fiber recruitment than that in low intensity training in the case of non-failure. This model is expected to help in understanding how impulses of different fiber types contribute and affect training.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44663813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, analysis of heart rate variability (HRV) offers an indirect, non-invasive assessment of ANS function. An irregular lifestyle and stress are known to affect ANS balance, influencing many diseases. Moreover, ANS disorder plays an important role in climacteric symptoms in menopausal females. The purpose of this study was designed to assess the effects of yoga practice sessions (herein re-ferred to as “yoga”) on ANS function and focused on the relationship between ANS function and subject age or personal history of yoga. A total of 113 healthy females participated in this study. They attended a 90-120 minute yoga practice session conducted by a well-qualified in-structor. ANS function was assessed before and after the yoga practice session by HRV power spectral analysis. As a result, in females, yoga reduced fatigue by primarily improving sympathetic activity. In addition, the LnHF values tended to be increased after yoga only in the over-60y (60 years) group. Furthermore, there were individual differences in the amount of change in the sympathetic and parasympathetic activity values. In females with a low activity level before yoga, values were increased; whereas values decreased in females with a high activity value before yoga. In subjects with ≥5-year history of yoga, there was no significant correla tion between the ANS parameters and subject age. Our study suggests that yoga for females supports well-balanced ANS function, and that the continuation of yoga over a period of time contributes to an improvement in ANS function.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48212148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although there is a possibility that physical activity improves empathy, the association of physical activity with cognitive and affective empathy in healthy humans remains unclear. Thus, the present study aims to clarify the relationship between levels of physical activity and selfreported empathy. Eight hundred and ninety-three responses for two questionnaires, the short version of the International Physical Activity Questionnaire (SV-IPAQ) and Questionnaire of Cognitive and Affective Empathy (QCAE), were analyzed. Levels of physical activity in a usual week were measured based on the SV-IPAQ, and participants were divided into three groups: low, moderate and high physical activity. The scores for cognitive and affective empathy were measured based on QCAE. We found that people with a moderate or high physical activity level show significantly higher self-reported cognitive empathy compared to people with a low physical activity level. The score for self-reported affective empathy wasn’t affected by physical activity level. Physical activity level in a usual week showed a significant positive correlation with self-reported cognitive empathy scores, but not with self-reported affective empathy scores. Our findings imply that an increase in physical activity contributes to better cognitive empathy in healthy young adults.","PeriodicalId":55847,"journal":{"name":"Journal of Physical Fitness and Sports Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42142401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mean BG level and the area under the curve for BG in the 24-hour period on the ST-EX day were significantly lower than those in the same period on the REST day (both p < 0.05). The duration of hyperglycemia (BG > 10 mmol/L) on the ST-EX day was significantly shorter than that on the REST day (p < 0.05).
