The toe flexor strength, indicated by the flexion function of the plantar and toe, is closely related to various physical fitness factors. Moreover, it has been clarified that performance is expected to improve by training the movement of toes. On the other hand, regular practice and pre-match warm-up are indispensable from the viewpoint of injury prevention and performance enhancement. However, some types and methods of warming up are ineffective in enhancing performance. We verified the effect of a novel warm-up method that utilizes the flexion motion of the toes. Therefore, in this study, we investigated whether a warm-up incorporating plantar and toe flexor movement was effective in improving the agility, jumping, and sprinting performances. This study included 40 male university students who belonged to the athletic club. They were randomly classified into four groups of 10 participants each: dynamic stretch (DS) group, plantar-toe movement group, DS + plantar-toe movement group, and control group. The participants were assessed for toe gripping force, Illinois test, standing long jump, and 20-m running both before and after warming up. According to the results of the Illinois test, the plantar-toe movement group and DS + plantar-toe movement group showed improvement after the intervention, and a significant difference was noted with respect to the time factors (P<0.01). Additionally, in the intergroup factors of the Illinois test after the intervention, a significant difference was observed between the plantar-toe movement group, DS + plantar-toe movement group and the control group (P<0.05). The results of this study suggest that warming up with the plantar and toe movement is effective in improving the, Acceleration deceleration, and turning around, which are the parameters of the Illinois test.

In recent years, the action of plantar and toes to play an important role in the movement ability of the elderly has been confirmed. Moreover, exercise using the toes is effective in improving the walking and balance of the elderly, and the need for toe exercise for the elderly is increasing. To date, there have been many reports verifying the effect of toe exercise over a long period of time, and there are few studies examining the immediate effect of toe exercise in the elderly. In this study, we examined the immediate effect of plantar and toe flexor exercise on the movement ability of the elderly. The study comprised 16 participants (3 male and 13 female; average age, 75.1±5.0 years). A crossover study was conducted by dividing the subjects into two conditions: control, and plantar and toe flexor exercise conditions. For plantar and toe flexor exercise, we performed a total of four types of exercises: (1) static stretching of the plantar and toe (2) towel gathering, (3) rock scissors and paper exercise, and (4) stepping on the foot plate. Additionally, toe flexor strength, toe’s ten-second test, 5 m walking time, 3 m zigzag walking time and TUG were measured before and after intervention to verify the immediate effects of plantar and toe flexor exercise. A two-way analysis of variance with both factors corresponding to each other showed that the toe flexor strength, toe's ten-second test, 5 m walking time, 3 m zigzag walking, and TUG measurement items were comparable between the two conditions after intervention. A significant difference was confirmed between the plantar and toe flexor exercise and control conditions. The results indicated that plantar and toe flexor exercise had an immediate effect on toe flexor strength, toe dexterity, and movement ability in straight line walking and direction changes.

Although there are a number of reported cases of increased cerebral blood flow during exercise, there are no reports on the relation between changes of blood flow during exercise and attentional function. The purpose of this study is to clarify the relation between changes of blood flow during exercise with AT intensity and attentional function, using near-infrared spectral analysis. The subjects were 10 healthy males. The research protocol was to conduct steady load exercise. We randomly conducted two invention trials: 1) an exercise/task trial in which a trail making test (TMT) was performed as an attentional assignment during steady load exercise, and 2) a rest/task trial in which TMT was performed during rest as a control. As a result, we observed the following: increase of oxy-Hb in the prefrontal cortex during AT exercise, the significant shortening of TMT during exercise from 69.1±10.2 seconds to63.2±7.2seconds, and, with further control, that the more oxy-Hb rises, the more TMT time is shortened. From these results, it is suggested that 10 minutes of exercise would improve attentional function, and furthermore, there is a possibility that increased cerebral blood flow may be involved with the improvement of attentional function.

The purpose of this study was to examine the effects of aquatic exercise training on the trunk muscles function and activities of daily living in abdominal obese women. Nineteen abdominal obese (abdominal circumference: 90 cm or more) and fifteen age-matched non-obese women were recruited as participants in this study. The aquatic exercise training (60 min/day, three days/week for 8 weeks) based on abdominal twists for activating the trunk muscle function. Physical parameters, biochemical characteristics, arteriosclerotic parameters and activities of daily living scores were assessed before and after the training period. In both groups showed abdominal circumference, percent of body fat, blood pressure and lower extremity muscle strength increased significantly after aquatic exercising training. In particular, endurance capacity of abdominal and back muscles increased significantly and activities of daily living scores were significantly improved in the obese group. Moreover, the improvement in the strength of lower extremities and improvement in the activities of daily living scores, such as climbing and descending stairs, in the obese group tended to be higher than non-obese women. Additionally, in abdominal obese group, the amount of the reduction of abdominal circumference was significantly associated with that of the increase in the strength of lower extremities. Taken together, these findings suggest the possibilities that the present aquatic exercise training based on trunk muscle exercise improving the function of trunk and lower extremity muscles with reduction in the abdominal obesity, contributing to improve activities of daily living in abdominal obese women.
