NCT02704546

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)

  • Rectal temperature

    2 experimental days for each participant

  • skin temperature

    2 experimental days for each participant

  • heart rate

    8 experimental days for each participant

  • lactic acid

    8 experimental days for each participant

Study Arms (2)

Methylphenidate

EXPERIMENTAL

In 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.

Drug: Methylphenidate

Placebo

PLACEBO COMPARATOR

In 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.

Drug: Placebo

Interventions

oral capsules (per os) each containing 10mg Methylphenidate.

Also known as: Ritalin®, MPH
Methylphenidate

capsules identical in shape, colour and size to the Ritalin® capsules, which contain only the inactive ingredients of the same formulation.

Placebo
