Objectives
Narrative objectives1
The purpose of this research is to use a sensor-equipped Ankle-weight(AW) (named as Power Walk and abbreviated as PW), which is an original device with a sensor attached to the AW, to conduct a simple interview when charging the PW during the intervention period and accumulating sensor data. Factors related to behavioral changes in the non-intervention period (post-observation 12 weeks) and frailty and falls of the elderly between the group (feedback group) and the non-feedback group (post-observation group) will be compared before and after PW wearing.

Interventions/Control_1
A group (feedback group) that uses a sensor built-in AW (named as Power Wolk: PW), which is an original device that attaches a sensor to the ankle weight (AW), to charge the PW during the intervention period and to have a simple interview when collecting sensor data. )
Interventions/Control_2
Non-feedback group (non-feedback group) during the non-intervention period (post-observation 12 weeks), behavioral changes and factors related to flail and falls in the elderly are compared and verified before and after PW wearing.

Key inclusion criteria
1) Those who are able to communicate in Japanese, understand the plan for recruiting volunteers through an appeal to the community, companies, administrative staff, and residents of facilities, etc., and are able to generally comply with the prescribed interventions and cooperate in the measurement.
2) Score on the Motor Fitness Scale (MFS, Questionnaire: Document 2) is at least 60% out of 14 (11 points for men and 9 points for women: http://www.pbhealth.med.tohoku.ac.jp/node/455#Page).
3) Applicants must be able to respond appropriately to questionnaires and impact studies.
4) Ankle weights with sensors should be selected at your own risk at a slightly higher weight (2% of the body weight per foot, see reference 5), and you should be able to wear the ankle weights with sensors (the weight can be changed during the intervention period) and walk outside for at least 20 minutes once a day, at least 2 days a week (you can divide the weight into smaller portions until you get used to it). There is no upper limit, but those who are willing to wear the equipment at their own risk and without strain, and who are willing to come to each facility periodically (approximately every 10-14 days during the intervention period) to collect data and recharge at home.
5) To wear the activity meter during the study period, except at bedtime, and to come to each facility regularly to recharge and collect data (approximately every 40 to 45 days during the study period).
6) Accident/Incident Note/Calendar for wearing out of the office (record of wearing out of the office) (
Those who are willing to fill in the notes/calendars (hereafter abbreviated as notes/calendars), complete nutritional surveys before and after the study period, and complete questionnaires at the end of the study.
7) Those who understand the above and have signed the consent form.
Key exclusion criteria
1) Young people under the age of 50
2) If you may be pregnant or are pregnant.
3) People who are using muscle enhancers, male hormones or corticosteroids used for doping (topical topical use is not applicable).
4) If your MFS score is less than 60% out of 14 (Overall judgement is based on 11 points for males and 9 points for females: http://www.pbhealth.med.tohoku.ac.jp/node/455#Page)
5) Those who have spontaneous pain, exercise pain, or serious diseases of bone, muscle, joint, or cardiorespiratory system, as determined by the doctor based on the presence or absence of joint or muscle pain such as back pain and knee joint pain at the hearing.
6) Those who are unable to take MRI images due to metals in the body, etc. (only MRI images are excluded)
7) Other persons deemed inappropriate by the principal investigator.
