This retrospective observational study aimed to examine the effects of playing Pokémon GO on daily steps of male college students. Twenty-five Japanese male college students (20 ± 1 years) were assigned to Control group (C, n = 11) or Pokémon GO group (P, n = 14) based on their playing Pokémon GO or not. Daily step levels were obtained from the health care app of Apple iPhone from September 2016 to October 2016. In P group, the data for the 4 weeks to determine baseline values and for the 4 weeks of playing Pokémon GO were analyzed. The steps data of C group were also analyzed in the same period of the total 8 weeks. There were no significant differences in steps at baseline level between both groups. In addition, no significant time-course changes in steps were observed in C group. In contrast, steps in P group significantly increased from baseline 8,368 ± 544 steps/day to week 1 10,028 ± 617 steps/day (P < 0.01). The changes in steps from baseline to week 1 were significantly greater in P group than in C group (1,671 ± 345 vs. -81 ± 582, P < 0.01). However, the increased steps returned to baseline level by week 2, and the values did not increase again. Therefore, our findings indicate that playing Pokémon GO increases daily steps only during one week in Japanese male college students.

背景:横断研究において,食事や睡眠の状況は学業成績状況と有意に関連することが報告されている.しかし,生活習慣と学業成績に関する大規模前向き縦断研究の観点で利用可能なデータはない.目的:そこで,本研究は,大規模な前向きの縦断的検証によって,大学初年次学生の食行動や眠気の状況が高年次の学業成績状況に影響するか,否か,検討することを目的とした.方法:食行動と眠気の両方の状況に応じ,2,351/2,328名の初年次大学体育授業の学生を四分位数に分類し,3年次終了時のTotal Grade Point Average(T-GPA)のスコア,およびそれぞれのCase(T-GPAが3.00以上となる,または,T-GPAが2.00より小さくなる)の発生に対する多変数の調整済みオッズ比(95%信頼区間)を比較した.結果:T-GPAは,Q1とQ2と比較し,Q4で有意に高い値を示し(なお,食行動や眠気の状況のスコアが,Q1は,不良を,Q4は,良好を示すものである),これらの差は,交絡因子で調整した上でも有意なままであった.食行動の状況において,Q1と比較して,T-GPAが2.00より小さくなるオッズ比は,Q3が0.60(0.45-0.72),Q4が0.64(0.48-0.86)であった.眠気の状況において,Q1と比較して,T-GPAが3.00以上となるオッズ比は,Q2が1.47(1.01-2.15),Q4が1.64(1.13-2.38)であった. 結論:我々の大規模な前向き縦断研究から得られた結果は,大学初年次学生の食行動や眠気の状況が,密接に,高年次のT-GPAの状況と関連していることを示すものであった.

Single-tooth sandals under new development have special material and shape characteristics. Exercises with single-tooth sandals can increase pressing stimulus on the soles of the feet, thereby suppressing a decline in medial longitudinal arch and elevating sole surface temperature. This study thus aimed to examine the effects of exercise with single-tooth sandals on medial longitudinal arch and sole surface temperature. Sixteen young adults (23 ± 5 years) participated in 20 min of stepping exercise on the spot. They randomly put on a regular normal sandal (N conditions) or a single-tooth sandal (Z conditions) on each left and right side. Before and after exercise, medial longitudinal arch and sole surface temperature were assessed by digital caliper and straightedge and thermography, respectively. No significant differences in baseline parameters were observed between N and Z conditions. After exercise, arch height and arch height ratio significantly reduced in N conditions, but not in Z conditions. Central sole surface temperature in Z conditions also increased significantly, and the changes in surface temperature were significantly higher in Z conditions than in N conditions. Therefore, these findings suggest that exercise with single-tooth sandals has a positive effect on a suppressing decline in medial longitudinal arch and an elevation in sole surface temperature.

The present study aimed to examine the effects of community-based intervention on cognitive function and hand finger dexterity in older adults at different levels of time to go out. Forty men and women (age, 73 ± 1 years) participated in supervised group activity and seated exercise for 60 min per session, once each week during an 8-week intervention. The participants wore an activity monitor for 1 week to determine baseline values and for the 8 weeks of intervention. Mini-mental state examination (MMSE) and pegboard test, which is related to cognitive function, were assessed before and after the intervention. Based on the total time to go out at baseline, the participants were assigned to Control group (> 60 min/day, n = 18) or Short group (≦ 60 min /day, n = 22), and then analyzed. After the 8 weeks of intervention, the Control and Short groups improved physical fitness parameters such as handgrip strength. Although MMSE in the both groups did not reach statistically significant level, these values tended to increase slightly from the baseline. Interestingly, two-way repeated-measures analysis of variance indicated significant interaction of pegboard test, and the score significantly increased only in the Short group. Total physical activity and moderate-vigorous physical activity in the both groups did not change significantly between the baseline and intervention periods. Therefore, these results suggest that the trainability of pegboard test, which is an index of hand finger dexterity and is related to cognitive function, would differ depending on the time to go out at baseline in older adults.

The present study aimed to examine the effects of Internet addiction on daily steps. A cross-sectional study was performed at the Osaka Institute of Technology. A total of 334 male college freshmen were analyzed. The participants were assigned to five groups according to Internet addiction levels. Internet addiction levels were assessed by Diagnostic Questionnaire, which has been reported by Young (1998), and we measured daily steps of the participants using a pedometer during usual 1 week. There were no significant trends or differences among five groups in physical characteristics of the participants, sleep duration, frequency of eating breakfast, and walking during commute time. However, with the level of Internet addiction increasing, daily steps showed a statistically significant decreasing trend. Therefore, Internet addiction levels might be related to reductions in steps in a dose-response manner. To clarify this point, further investigations will be required after considering confounding factors.
