Brief Summary

The purpose of this graduate student study is to determine if ingestion of dark chocolate (70% cacao) will change brain frequencies between visualization at a state of rest and a state of exercise performance via electroencephalography (EEG) in vigorously active individuals.

Conditions

Healthy

Outcome Measures

Primary Outcomes (2)

• EEG Wave Band Activity without dark chocolate ingestion

  The EEG, electroencephalogram, is a test that detects abnormalities in the brain waves or the electrical activity of the brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto the scalp. The electrodes detect tiny electrical charges that result from the activity in the brain cells. EEG wave band activity will be recorded from 9 cerebral cortical scalp locations: F3, Fz, F4, C3, Cz, C4, P3, Pz, and P4 using the EEG B-Alert 10X System, Carlsbad CA. Each of the brain frequencies will be measured in 5 second increments. Data collection will last no longer than 2 hours for each session.

Study Arms (2)

dark chocolate

EXPERIMENTAL

Three EEG measurements will be recorded: 1) at baseline, 2) during visualization of rest for one minute, and 3) during visualization of usual vigorous exercise for one minute. Measurements 2 and 3 will be recorded savoring dark chocolate and after fully ingesting the dark chocolate respectively.

Dietary Supplement: dark chocolate

non dark chocolate

ACTIVE COMPARATOR

three EEG measurements will be recorded: 1) at baseline, 2) during visualization of rest for one minute, and 3) during visualization of usual vigorous exercise for one minute.

Other: non dark chocolate

Interventions

dark chocolate DIETARY_SUPPLEMENT

Participants will be provided Parliament dark chocolate (70% cocoa) from Redlands, CA. The Parliament chocolate is made with cacao and cane sugar. Each participant will be given half a piece (1.4 g) of dark chocolate to consume for this experiment over three minutes.

non dark chocolate OTHER

No dark chocolate will be given to this group during the procedures.
