Brief Summary
The purpose of this study is to explore the possible effects of MPH use on physiological functions among ADHD\\ADD patients, by performing a set of physical trials to assess aerobic and anaerobic capacity, to characterize the tendency for muscle break down while performing monitored moderate physical effort and to assess the physiological strain while performing moderate exercise in heat load conditions by using the heat tolerance test.

Conditions
Outcome Measures
Primary Outcomes (2)
physiological strain (composite)
the physiological strain will be determined by monitoring body core temperature and heart rate of the subjects during a Heat Tolerant Test (HTT). the test is performed in a climatic chamber. during the test the subjects walks on a treadmill (5 km/h and 2% incline) for 2h.
2 experimental days for each participant
aerobic capacity
the aerobic capacity of the subjects will be determined by performing a maximal oxygen consumption test (VO2max). VO2 will be monitored continuously with a metabolic system (ERGOTEST 680, ZAN, GERMANY ).
2 experimental days for each participant
Secondary Outcomes (4)

Study Arms (2)
Methylphenidate
EXPERIMENTALIn experimental days taking MPH, subjects will take 20mg Ritalin® (Novartis AG) in two tablets of 10mg, by swallow 1 hour prior to performing the physical test.
Placebo
PLACEBO COMPARATORIn experimental days with placebo subjects will be asked to ingest 2 capsules identical to Ritalin® capsules, by swallow 1 hour prior to performing the physical test.
Interventions
oral capsules (per os) each containing 10mg Methylphenidate.
capsules identical in shape, colour and size to the Ritalin® capsules, which contain only the inactive ingredients of the same formulation.
Eligibility Criteria
You may qualify if:
- Civilian volunteers aged 18-25 years.
- BMI range of 17-25.
- Diagnosed with attention deficit disorder (ADD or ADHD) since childhood.
- Routine use of Methylphenidate (at least 5 days a week).
- Without known medical illness or medication use.
- Report of performing physical exercise (twice or more a week).
- Without history of heat injury.
You may not qualify if:
- The existence or suspicion of existing cardiac or respiratory disease.
- Infectious disease 3 days prior to the experiment.
