Abstract This study aimed to investigate the relationship between toe muscular strength and the ability to change direction in athletes. Seventeen collegiate American-football players participated in the study (age 19.9 ± 0.9 years, competition experience 7.3 ± 1.7 years). Two types of measurements were performed to evaluate toe muscular strength: toe flexor strength with the metatarsophalangeal joint in the planter flexed position and toe-pushing force with the metatarsophalangeal joint in the dorsiflexed position. The ability to change direction was evaluated using the pro-agility and 3-cone tests and change of direction deficits, calculated by subtracting the sprint times from the pro-agility and 3-cone times. There were significant correlations between toe-pushing force and the results of the pro-agility and 3-cone tests, but no significant correlations between toe flexor strength and the pro-agility and 3-cone tests. Neither toe-pushing force nor toe flexor strength was significantly correlated with the sprint test results. Furthermore, toe-pushing force was significantly correlated with the 3-cone test deficit, but toe flexor strength was not. The ability to change direction is more strongly affected by toe muscular strength (measured as toe-pushing force) with the metatarsophalangeal joint in the dorsiflexed angle than by toe muscular strength (measured as toe flexor strength) with the metatarsophalangeal joint in the plantar flexed angle. Our results suggest that athletes can improve their ability to change direction with toe muscular strength training with the metatarsophalangeal joint in the dorsiflexed position.

Abstract Background: Hallux valgus and lesser toe deformity reduce the strength of the toe flexors and are a cause of falls in older people. This study aimed to examine the differences in toe flexor strength and foot morphology in older people requiring long-term care due to changes in the way they mobilize in everyday life.Methods: Eighty-four people aged ≥70 without motor paralysis who are undergoing or had undergone ambulatory rehabilitation. They were divided into those who could mobilize without a wheelchair (walking group, n=54) and those who used a wheelchair to mobilize (wheelchair group, n=30). Presence of diseases, hand grip strength, toe flexor strength, and foot morphology were compared between the two groups.Results: No significant between-group difference in foot morphology was found. Factors related to differences in the means used to mobilize in daily life were a history of fracture, heart disease, and toe flexor strength. In muscle strength of the wheelchair group compared with the mean values of the walking group, the toe flexor strength was significantly more decreased in relation to hand grip strength.Conclusions: Older people who use a wheelchair to mobilize have significantly less toe flexor strength than those who do not despite having no significant difference in foot morphology. Use of a wheelchair is associated with a reduction in toe flexor strength.

Abstract Background: Older adults are known to have more pronated foot posture and decreased toe flexor strength (TFS), as well as decreased mobility in daily life compared to young adults. Although foot posture is reported to be an influential factor for walking biomechanics in young adults, there is less information on this subject in older adults. Age-related reduction in TFS is shown to be associated with impairments of functional performance, but it is poorly understood whether foot posture influences the relationships between TFS and functional performances. Therefore, the present study aimed to elucidate this concern by examining older women. Methods: Seventy community-dwelling older women (76.8 ± 4.4 years) voluntarily participated in this study. Foot posture was evaluated by the 6-item foot posture index (FPI). Based on the FPI score, participants were allocated to pronated, neutral, or supinated group (n = 33, 26, and 11, respectively). TFS was assessed using a toe grip dynamometer in a seated position. Scores of 30-second chair stand, timed up-and-go, 5-m comfortable-speed walking, and static balance tests were determined to evaluate functional performances. Pearson’s correlation coefficients were computed to examine the relationships between TFS and functional performances in each group. Results: TFS positively correlated with comfortable walking speed in the pronated (r = 0.37, p = 0.03) and supinated (r = 0.76, p < 0.001) groups, but not in the neutral group (r = 0.17, p = 0.42). For the two significant relationships, an analysis of covariance showed that there was no significant difference between the pronated and supinated groups in the slopes of the regression lines, suggesting a similar relative contribution of TFS to comfortable walking speed between the two groups. In addition, TFS tended to negatively correlate with timed up-and-go time in the pronated (r = -0.32, p = 0.07) and supinated (r = -0.56, p = 0.08) groups, and positively correlate with 30-second chair stand score in the pronated group (r = 0.31, p = 0.08). Conclusions: The present study indicates that TFS would be associated with mobility, walking performance in particular, in older women with pronated and supinated feet but not with neutral feet.

This study aimed to explore the relationship between toe flexor strength and the daily activity levels in 56 Japanese older women aged between 70 and 88 years. The activity levels were measured as the average number of steps/day using a pedometer and the life space assessment (LSA) scores. The Mann–Whitney U test was used to compare toe flexor muscle strength and the LSA scores between those with fewer than and more than 6,000 steps/day. Spearman’s correlation coefficient was used to investigate the relationship between toe grip strength according to age and each variable. The LSA scores were significantly higher in the group with >6,000 steps/day (β = 0.188, p < .05). A correlation was found between the number of steps/day and toe flexor strength (r = .424, β = 0.419, p < .05) and the LSA scores (r = .417, β = 0.435, p < .05) in the participants in their 80s. Increasing the number of steps/day may benefit women in their 80s.

AbstractWhether practicing in judo influences the muscle strength and morphological characteristics of the foot is unknown. The purpose of this study was to determine the toe flexor muscle strength and morphological characteristics of the foot in judo athletes. Judo athletes (JUDO, men=24) and age-, gender- and body mass-matched physically active healthy subjects (CON, men=24) were recruited, and their toe flexor strength and morphological characteristics of the foot were compared. The maximum isometric toe flexor strength and foot intrinsic muscle thicknesses were measured using a toe grip dynamometer and a B-mode ultrasound, respectively. Foot arch height was assessed as the distance between the navicular tuberosity of the foot and the floor in the sitting and standing positions. JUDO showed a significantly lower foot arch height and smaller foot arch index than CON, whereas foot length and muscle thickness did not significantly differ between groups. The toe flexor strength relative to total muscle thickness was significantly larger in JUDO than CON. The foot arch dynamics was significantly larger in JUDO than CON. This study suggests that exercise training specific to judo may affect the force-generating capacity, morphological structure and arch function of the foot.
