The ratio of limits of stability (LOS) to base of support (BOS) should be large. However, balance tests often inadequately address LOS and tend to overlook BOS. Moreover, higher difficulty levels may hinder some middle-aged and elderly individuals from performing these tests. This study aims to explore variations in foot breadth (0 cm, 10 cm) and the day-to-day reliability in rate of LOS per BOS (LPB) of two motions, examining relationships between LPBs in ten middle-aged and elderly males. Day-to-day reliability demonstrated a moderate or larger extent. The LOS for rotational motion was <40% of BOS, whereas for tilting motion, was approximated 50% of BOS. Ultimately, LPB increased with the widening of foot distance in both motions. Furthermore, there was a strong relationship between the LPBs.

The impact of age, living space, and driving on physical fitness and motor abilities in the elderly may vary across different age groups. This study aimed to examine the associations between age, living space, driving, and physical fitness and motor abilities using structural equation modeling to elucidate the relationships among these factors. The analysis found no significant relationships among the factors in the early-stage group. However, in the late-stage group, significant associations emerged between age and living space with physical fitness and motor abilities. Significant correlation was observed between Living Space Assessment and both knee extension strength and hip joint mobility. While driving did not show a direct impact, age and living space notably influenced at least lower limb strength and hip strategy, emphasizing the importance of these factors in maintaining motor abilities in late-stage elderly women.

The step count is considered a crucial indicator for maintaining and enhancing health in the elderly. However, many seniors do not walk adequately. Using them to support an increase in the number of steps might be effective in Japan, where the ownership rate of smartphones is increasing. This study investigated the association between “digital peer support” and increasing the number of steps among elderly individuals using smartphone application. These findings emphasized that digital peer support using smartphone application may increase the step count of elderly females by approximately 1,000 steps per month.

Journal of Hokuriku Society of Sport Sciences and Physical Education 4 15 - 27 2023.3

People have a high probability feeling embarrassment with respect to dance. For this reason, it is important that instructors or participants accurately evaluate the performance of the subjects, immediately connect failures to successes, and inspire confidence in the activity. This study aims to examine the assessment items to easily judge accomplishments in moonwalking in street dance. According to the results, the values of six items (foot switching, knee extension, load on the tiptoes, precision, up-and-down movement, and smoothness) were found to be moderate or higher. In conclusion, the above six items were judged to be effective in terms of easily evaluating moonwalking.

Starting from March 2, 2020, schools of every kind were temporarily closed to prevent COVID-19 infections. Despite dispersed school attendance being enforced during the closure, temporary school closures continued until the end of May. Elementary and junior high school students’ exercise habits changed because they could not step out of their homes unless necessary or during an emergency. Accordingly, the purpose of this study was to evaluate the changes in exercise time before and during temporary closures among 5,619 elementary (boys and girls) and junior high school (male and female) students in three stages by school grade and gender, namely, increased, unchanged, and decreased. The impact of each factor, athletic organization affiliation, and parental involvement varied based on grade and gender; however, if parental involvement was less than twice per week, exercise time decreased for the majority of children and students.

Eating disorders are serious life-threatening illnesses, and the risk of onset is particularly high in female athletes. Eating disorders tend to be caused by continuous abnormal eating behaviors; thus, early detection is important. This study aimed to develop items for screening female athletes with abnormal eating behaviors, which are precursors for eating disorders. Ultimately, 15 items pertaining to eating behaviors, weight, and self-evaluation/evaluation by others were considered potentially useful for easily identifying female athletes with abnormal eating behaviors.

In soccer, in addition to skills improvement, raising the tactical understanding of the coach leads to an improved team performance. The purpose of this study was to make a longitudinal inspection of how tactical understanding is impacted by changes in the ability to make decisions and the ability to convey information, which are thought to be related to the tactical understanding of the coach. As a result of the analysis, for the ability to make decisions and the ability to convey information, the increase group had a significantly higher rate of change than the decrease group with regard to tactical understanding. To raise the level of tactical understanding, it is important to increase the ability to make decisions and to convey information.

Humans maintain a center of pressure (COP) that is virtually united in a vertical direction of center of gravity to maintain an upright standing posture in the base of support (BOS). However, the COP cannot move until there is an edge of BOS. Actually, it can move only until there is an edge of the inside functional BOS [limits of stability (LOS)]. This study aimed to examine the difference between the foot breadth (0 cm, 10 cm) and the day-to-day reliability in a rate of LOS for BOS (LOS per BOS: LPB). Our outcomes demonstrated that not only BOS and LOS but also LPB increased the foot breadth and differed little from the interday variation.

This study clarified the actual status of efforts related to physical education during the temporary closure of schools due to the spread of COVID-19, using a case study. Many schools mainly used "distribution of study handouts for exercise tasks" as a learning method, and the percentage of learning methods of "video viewing" and "online conference system" were low. Problems pertaining to the implementation of home learning of physical education were difficulty in creating specific tasks that are different from those of the main subjects, home Internet and ICT equipment ownership, and the lack of time to create exercises.

Even while riding a bicycle for a short time, the load on the legs is largely dependent upon the saddle height. Elderly riders often lose their balance after dismounting the bicycle and may fall. This study aimed to examine the relationship between saddle height and balancing ability following the short pedaling exercise. In the case of the saddle height (85%, 90%, 95%, and 100% of the lower limb length) set in this study, the balancing ability decreases after dismounting the bicycle; however, no difference occurs according to the saddle height.

This study aims to examine the factors related to understanding the coach’s tactical strategies from the perspective of logical ability. We evaluated players’ level of understanding regarding the coach’s tactics through video tasks. The students were then classified into high-, middle-, and low rank groups in depending on their scores. The low rank group exhibited low levels for “speed of judgment on the flow of the game” and “willingness to share ideas with teammates,” suggesting that these aspects significantly influence tactical understanding.

Some people cannot achieve or maintain a stable posture on an unstable stool, even the elderly with high independence in activities of daily living. Elderly women who cannot perform such movements by leaning sharply in the backward and forward directions have more fall experiences and poorer results on the one-leg standing (OLS) with open eyes test, walking ability, and ADL compared with the elderly individuals who can perform this movement. In this study, we examined differences between the elderly females who could maintain a stable posture on an unstable stool by leaning sharply in the right and left directions for 20 s (possible group [PG]) and those who could not maintain this posture (impossible group [IG]) for motor skills and fall experience. Compared with IG, PG was superior in the OLS test, but no significant difference was found for other parameters or fall experience between the groups.

Although the risk of lifestyle-related diseases increases with aging, the combination of various related diseases may differ according to age and sex. The objective of this study was to determine the prevalence of hypertension, dyslipidemia, and diabetes mellitus and verify age-related differences in each sex. The prevalence in each sex was calculated with respect to age group (8 ways: every 5 years from age 35) and disease status (8 ways). hat the disease status differed in all age groups. Regarding the prevalence for each disease, males were more prone to have diabetes mellitus and females were more prone to have hypertension than other diseases. On the other hand, regarding the prevalence of combined diseases, the combination of hypertension and diabetes mellitus tended to be more prevalent than other combinations in both sexes.
