The experimental group (EG) participated in a once a week physical exercise program for 8 weeks. The session consisted of balance training, followed by aerobic endurance training with exercise peddlers. At the beginning of the program, each session lasted 25 minutes and progressed to 35 minutes, in the last two weeks

The control group (CG) only performed routine balance exercises once a week (10 min)

Balance program (10 minutes)

Balance on bosu ball and ball drills Coordination in rings with single leg stance and ball drills Straight line walk with head up Straight line walk and hip flexion, knee flexion and head up

(Duration: 10 minutes. Sets: 2 minutes per exercise. Rest: 30 seconds between exercises)

The Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) evaluates the degree of symptomatology of the person with Parkinson's Disease. The total score range ranges from 0 to 200, with higher values indicating a greater impact of the symptoms. Each item is scored from 0 to 4, with 0 being the least and 4 the most severe. The scores are added.

The quality of life questionnaire for Parkinson's disease is a specific questionnaire that evaluates the quality of life, where a lower score means that the patient has a better quality of life. It consists of 39 questions, and its value is expressed in percentages, the percentages closest to zero express a better quality of life. In addition, their results can also be expressed in 8 different areas (mobility, activities of daily life, stigma, emotional well-being, social support, communication, body discomfort, cognitive impairment), which are interpreted in the same way.

The Senior Fitness Test, is a battery of 7 tests to evaluate the physical state of the elderly, and has been validated for people with Parkinson's Disease. This battery evaluates the strength of lower and upper limbs with the 30 seconds chair stand and arm curl tests, to more repetitions, more strength. It also evaluates the flexibility of both lower and upper limbs with the chair sit and reach and back stractch tests, which are measured in centimeters, to more centimeters greater flexibility. Aerobic endurance is assessed by means of the 6 minute walk test that is measured in meters, and the 2 minute step test that is measured in cycles. The more number of cycles and meters, the better aerobic resistance. The balance is evaluated by means of the 8 foot up and go test, which is measured in seconds, and the less the better the balance. These results by means of a mathematical formula give an absolute value that to higher score better physical condition
