Clinical Trial Summary

This is a control study with a 2-group pretest-posttest design investigating the effects of a 10-week judo-inspired exercise program (Judo4Balance) for physical functions, self-efficacy, activity level, and fall techniques among working adults & part-time working retired people.

Falls constitute a common and severe threat to older men and women's health worldwide. However, falls are not just a problem of advanced age, studies have been reporting that falls are a problem at all ages. Nevertheless, falls are under-studied, particularly among young and middle-aged adults (working age adults). For all fall-related injuries among adults, the proportions have been reported to be 32.3% among older adults, 35.3% among middle-aged adults, and 32.3% among younger adults in the United States. This indicates that falls and fall related injuries represent a significant threat to public health at all ages. Therefore, new innovative ways of prevention is much needed and needs to be studied.

Description:

The aim of this study is to evaluate and document whether a ten week standardized judo inspired exercise program (Judo4Balance) which include both training the physical qualities such as strength and balance as well as the "break fall" technique can influence the risk of falling as well as reduce the negative consequences of an accidental fall.

Questions asked:

• Can a ten week standardized judo based exercise program improve the "break fall" competence among adults ?

• Can a ten week standardized judo based exercise program improve the fall-efficacy at home and at work among adults ?

• Can a ten week standardized judo based exercise program improve the physical status with regards to the risks for falls among adults ?

• Can a ten week standardized judo based exercise program improve the balance among adults ?

• Could a ten week standardized judo based exercise program be a useful tool in an organisation's preventive Health and Safety work.

The study included two groups with ethical approval to recruit up to 100 individuals in the intervention group and up to 100 individuals in a control group. (control participants are selected mainly the same workplace where the group exercises are being performed and consists of a similar sample of age, sex and physical status ).

The study is conducted in accordance with the Declaration of Helsinki. This study was approved by the Ethical Committee of the Uppsala Region (Dnr 2018/239). Each participant voluntarily provided a written informed consent before participating. Participants were informed that they could withdraw from participation at any time for any reason without any consequences. The participants received no compensation for participating in the study.

A total of seven different workplaces from different parts of Sweden participate in the study of the judo-inspired exercise program (construction and steel industry, healthcare, pre-school, insurance office, advertising, and health and safety consultants). Judo Clubs from different locations in Sweden as well as an insurance company offered the program as part of their preventive Health and Safety at the workplace program. Workplaces report an interest in participating and view their participation as part of their systematic work to promote Health and Safety among employees. Information and an invitation to participate in the 10-week program were provided to employees at the workplace setting.

After an acceptance to participate, written consent is obtained. Measurements were performed at the workplace by a qualified judo instructor.

A total of three qualified Judo instructors, familiar with the physical tests performed the pre- and post-assessments. A total of 14 qualified judo instructors provide instructions in the different groups (on average, 2 instructors per group of 10-18 persons). The instructors teaching the special exercise program are required to have at least a blue belt in judo (which means a minimum of 5 years of regular judo and break fall training). All the instructors teaching the classes in the study have black belts. To teach the program, there are also a requirement to have a coaching license from the Swedish Judo Federation and to have undergone a specific weekend course in the Judo4Balance program, with a focus on teaching judo-related exercises and fall techniques to adult beginners.

The program is delivered in a 45-50-minute session once a week for ten weeks at the respective workplace or other suitable location for the group exercise. The 10 week program is divided into three blocks and taught by experienced and especially trained judo instructors.

Block 1: Good technique during break fall training and strength training, accustomed the body to regular training, find the right level of training for the group, build up load resistance in muscles, tendons and bones. Challenge the balance through new movements not used everyday. Flexibility training for stiff joints such as neck and upper back.

Block 2: Improve "break fall" technique and strength exercises, increase the loads and further challenge the balance and coordination, increase range of motion and introduce "power training".

Block 3: Train the skill of explosive power during strength exercises and break falls. Challenge the balance with increased complexity and difficulty.

The participants both in the intervention group and control group are tested before and after the 10 week period. After the tests have been carried out a questionnaire is to be sent out to the instructors to get their evaluation of the suitability and effectiveness of the program at the work place. A similar questionnaire will be sent out to the participants to evaluate their experience of this preventive program from a Health and Safety at work perspective.

There is strong evidence that exercise can reduce the risk of falling. Nevertheless, judo based training has not to the investigators knowledge been scientifically investigated for working adults with the aim of reducing falls at the workplace and elsewhere. Neither has it been studied if this type of group training is motivational for continuing physical activity after the intervention or for improving the health and safety among employees.

Intervention

Behavioral:
• Active Comparator: Participants in 10 week Judo Inspired Exercise program
The intervention included 10 sessions, using a 10-week (45-50 minutes /week) pre-established program called Judo4Balance, a structured exercise program. Each session consisting of warm-up, balance, strength, power and break fall exercises. There is clear a progression within the 10 week program in three main blocks. Block 1: learning the exercises and principle movements, Block 2 more resistance and advance falling techniques, Block 3 Power training and falling strategies from stand up positions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in participants "break fall" competence/skill	Two tests have been developed to test the skills for falling backwards as well as falling forwards in a safe setting, with progressive difficulty. Four Judo puzzle mats are needed for the test. The "break fall" technique froward and backward are graded from a 0-4 point scale. (where 0 is not being able to lay down and get up from the floor and 4 is being able to fall safely from a standing up position, thus representing the best score).	Before and after 10 weeks of training
Primary	Change in participants' fall efficacy after 10 weeks	The change in falls-efficacy will be measured through - Modified Falls-Efficacy Scale - Falls Efficacy Scale-Swedish version (FES-S) and Falls Efficacy Scale-Swedish version for working age (FES-S-W) is used to measure the self-confidence in the ability to perform various daily activities without falling.The FES-S-W was extended with six additional questions, with the aim to ask people of working age about their confidence related to falling as well as their confidence of not getting hurt when falling. The original instrument consists of 13 items and the extended test 19 items. Each item is rated from 0 to 10, with a maximum score of 130/190 points, which represents the highest level of self-efficacy. The original instrument has been shown to have high test-retest reliability.	Before and after 10 weeks of training
Primary	Change in Balance	The Mini-BESTest and Mini-BESTest- W were used to measure balance. The original test includes 14 different tasks on 4 subscales. The extended test includes six additional items: feet shoulder-width apart, on toes for extended time (30 seconds); feet together, eyes closed and on toes; walking backwards; walking backwards on a line; standing on one leg on a foam surface left/right; change in gait speed backwards; and step over obstacles backwards. All tasks are graded from 0 to 2 points, with a total maximum score of 28 points for the original test and 40 points for the extended test. The higher the score the better the performance. The original test has high reported test-retest reliability and interrater reliability.	Before and after the 10 weeks of training
Secondary	Short Physical Performance Battery (SPPB-W)	Short Physical Performance Battery (SPPB) is used to assess the physical performance in the lower extremities, which was expanded with an additional difficulty progression to suit people of working age (W). The additional progression included advanced items in each of the three components: balance (tandem with heel raise, and tandem with heel raise with closed eyes), gait speed (backwards), and lower body power (chair stand on one leg -left/right). The original scale scores range from 0 to 4 for three components, with an additional score of 20 for the additional items. A total score of 12 represents the best performance for the original test and 32 the best score for the expanded test. The original SPPB has shown to predict the risk of falls in adults over the age of 60. The test has shown to have good test-retest reliability and being sensitive to changes.	Before and after 10 weeks of training
Secondary	Change in level of Physical Activity	Frändin/Grimby Activity Scale is used to measure the level of physical activity. Three different questions are used capturing activity levels during summer, winter, and at the workplace. The scales range from 1 to 6, with 1 representing 'hardly active at all' and 6 representing 'intensive exercise regularly and several times per week.' The original scale has been evaluated and shown to have good validity.	Before and after 10 weeks training
Secondary	Judo4Balance Instructors perception of the suitability and effectiveness of the program	A questionnaire will be sent out to the instructors to capture their view the exercise program and its effects on the participants and the workplace environment from a workplace practical and Health and Safety perspective. The initial three questions are graded on a scale from 1-10 where 5 represents "meets expecations" and 1 "not at all meet expectations" and 10 " highly exceeds expectations. The last questions are open questions.	After the 10 weeks of training
Secondary	Judo4Balance - Participant Survey	An anonymous survey will be sent out to the participants (after training and testing is finished) to catch their perception of the program from a work place "Health and Safety" perspective. Indicators such as: met expectations, team building, continued interest in exercising and joy at the workplace will be asked. The initial questions are graded on a scale from 1-10 where 5 represents "meet expectations or agree" and 1 "not at all meet or agree" and 10 represents "highly exceeds expectations". There are also some open questions.	After the 10 week program
