“…The measured items of the Japan Fitness Test intended for the age of 65 to 79 are Grip Strength, Sit-and-reach, Standing Foot Balancing with Eyes Open, 10-m Hurdle Walk, Sit-ups, and 6-minutes Walk. In previous studies (Nishijima, et al, 2003b;Nishijima, et al, 2003c), it has been reported that the six items of the Japan Fitness Test suggest signifi cant construct validity coeffi cient (0.35 to 0.87), and that high value of reliability (r = 0.93 or more) was obtained. In accordance with the manual of Japan Fitness Test intended for the age of 65 to 79 (the Ministry of Education, Culture, Sports, Science, and Technology; MEXT hereafter, 2002), the measurement was conducted and the total scores of the test were calculated.…”

This study examines the validity for estimating physical fi tness age (PFA) using the Japan Fitness Test through the application of single and multiple regression analyses and principal component analysis. The participants were 484 community-dwelling Japanese elderly men and women. A Physical fi tness test consisting of 6 performance tests, namely grip strength, sitting trunk fl exion, foot balance with opened eye, 10-m hurdle walk, sit-ups, and 6-min walk were used. Participants were divided into two groups for modeling PFA equations (n = 322) and for cross-validation of them (n = 162). The equation models for estimating the PFA were a single regression model with a physical fi tness test score, a multiple regression model with the 6 performance tests, and the fi rst principal component model obtained from the 6 performance tests. The validity of three PFA models was compared by concurrent validity with chronological age (CHA), cross-validity using shrinkage, and degree of agreement between aging effect for physical fi tness and the correlation coeffi cients of PFA and CHA. Results of statistical analyses reveal that the three PFA models satisfy concurrent validity and cross-validity, but the single regression PFA model detected a greater degree of agreement for aging than the other models.

“…Nishijima, et al, (2003) have reported that the middle-aged and elderly individuals, who participated in muscle strength training with the use of machines and in aerobic training by step exercise with the aim of improvement in walking capacity, improved in 10-meter obstacle walk signifi cantly. He has also been reported that the 10-meter walking with hurdles test is appropriate as a simplifi ed measurement item because the test requires participants to use their muscle strength of femoral and iliopsoas muscle groups fully.…”

This 1-year intervention study was designed to examine the effects of exercise and nutritional intervention on the improvement of physical factors associated with fracture risk in middle-aged and older women. One hundred twenty-six women aged 55-75 years were divided into one of 3 groups: an exercise group, an exercise and nutrition group, and a control group. Nutritional intervention was designed to encourage women to obtain suffi cient daily protein (65g or over) and calcium intake (600mg or over). The setting was center-based and home-based exercise. Measurements were bone stiffness, one-leg stance, whole body reaction time, grip strength, 10m obstacle walk and 30-second chair stand. Results show that exercise intervention can signifi cantly improve physical ability in older women with regard to one-leg stance, whole body reaction time, 10m obstacle walk and 30-second chair stand, suggesting that older women are able to ameliorate fall risk factors by exercise intervention. The exercise and nutrition group had success in modifying bone loss when compared with the exercise group, suggesting that multimodal intervention that includes exercise and nutrition targeted at correcting bone loss should be recommended. The results suggest that exercise and nutritional intervention may be an effective approach to fracture prevention in middle-aged and older women.

“…Locomotor Performance Tests to Assess Locomotion-Related Functional Limitations. For the 10 m hurdle walking test [16], hurdles with a height of 20 cm, width of 10 cm, and length of 100 cm made from Styrofoam were placed at 2 m intervals. As such, a total of six hurdles were placed from the start line (0 m) to the finish line (10 m).…”

Background. Functional issues (impairments, functional limitations, and disabilities) gradually occur with age. Nonetheless, maintaining physical capability may help prevent locomotion disabilities at an older age. The present study aimed to determine whether reductions in muscle strength and range of motion (ROM) cause locomotion disability via locomotion-related functional limitations among healthy older adults. Methods. Data from a total of 144 participants (61 men, 83 women) were analyzed. To assess locomotion disability, the locomotor domain of the activities of daily living (ADLs) survey from the Ministry of Education, Culture, Sports, Science, and Technology of Japan was used. Muscle strength (grip strength) and two ROMs (hip flexion and knee flexion) were measured. To measure locomotion-related functional limitations, participants underwent a 10 m hurdle walking test and side-step test. Thereafter, path analysis was conducted for testing the hypothetical model. The goodness of fit in the model was assessed using statistical parameters, such as the chi-square value, goodness of fit index (GFI), adjusted goodness of fit index (AGFI), comparative fit index (CFI), and root mean square error of approximation (RMSEA). Results. The analysis revealed a nonsignificant chi-square value (chi-square = 41.885; p = 0.113 ), as well as high values of GFI (0.944), AGFI (0.904), CFI (0.970), and RMSEA (0.046), indicating that locomotion disability was caused by locomotion-related functional limitations, which were influenced by muscle strength and ROM. Conclusions. The present study demonstrated that decreased muscle strength and ROM caused locomotion disability via locomotion-related functional limitations. Older adults should participate in physical exercise programs that focus on strengthening muscles and improving ROM to counteract age-related locomotion disability.
