The aim is to establish adequate and suitable protocols for PD patients and to determine the WB-EMS effects on muscle strength, balance, walking, cognitive functions,neurotrophic factors and alpha-synuclein. Thirty-six PD patients, aged from 50 to 80 years, will be recruited and randomly assigned to two experimental groups (EGs and EGc) and one control group (CG), in order to perform dynamic movements with WB-EMS. EGs will undergo to 12-20 minutes of progressive supervised WB-EMS (4 sec. 85 HZ and 4 sec. rests) combined to light dynamic movements, two-time per week for 12/24 weeks. EGe will undergo to 12-20 minutes of progressive supervised WB-EMS 7 Hz) combined with cardiovascular training with rowing machine. CG will not perform any type of physical activity. Pre and post intervention assessment will be carried out on the following areas: physical assessment, neurocognitive, neurotrophic factors and alpha-synuclein assesments. A 3 months follow-up will be performed.

Inclusion Criteria:

• age from 50 to 80 years old
• clinical diagnosis of parkinson's disease from 1 to 3 of Hoehn and Yahr Scale
• no partecipation to other physical activity program

Exclusion Criteria:

• MMSE values < 24
• inability to walk 6 minutes without assistance
• use of medications and other things that may affect cognitive and motor functions
• presence of contraindications in the use of WB-EMS
