Outcome Measures
Primary Outcomes (5)
Change in Exercise-Related Neutrophil Chemotactic Velocity
Participants will ride a stationary bike and maintain their target heart rate for 30 min. Blood samples via lancet will be collected at baseline, 30 min (immediately post intervention), and 60 min.
baseline, 30 min, 60 min
Change in Caffeine-Related Neutrophil Chemotactic Velocity
Participants will consume a moderate dose of caffeine via 200mg capsule. Blood samples via lancet will be collected at baseline, 30 min (immediately post intervention), and 60 min.
baseline, 30 min, 60 min
Change in Ethanol-Related Neutrophil Chemotactic Velocity
Participants will consume a weight-calculated dose of alcohol sufficient to increase their blood alcohol concentration (BAC) to 0.05. Blood samples via lancet will be collected at baseline, 1-3 hours (when BAC reached 0.05) and 1 hour after previous collection.
baseline, 1-3 hours from baseline, up to 2-4 hours from baseline
Change in Glucose-Related Neutrophil Chemotactic Velocity
Participants will consume 100g glucose tolerance drink within 5 minutes. Blood samples via lancet will be collected at baseline, 30 min (immediately post intervention), and 60 min.
baseline, 30 min, 60 min
Change in Caffeine Plus Glucose-Related Neutrophil Chemotactic Velocity
Participants will consume a moderate dose of caffeine via 200mg capsule and 100g of glucose tolerance drink within 5 min. Blood samples via lancet will be collected at baseline, 30 min (immediately post intervention), and 60 min.

Study Arms (5)
Cardiovascular Exercise
EXPERIMENTALParticipants will ride a stationary bike and maintain their target heart rate (according to the American Heart Association guidelines) for 30 minutes. For example, a 30 year old will have a target heart rate zone of 95-162 beats per minute. A baseline blood sample will be acquired before the participant begins exercising. In the following 30 minutes, participants will ride the exercise bike, and their heart rate and general status will be assessed continuously. Specifically, heart rate will be monitored using a chest strap heart rate monitor. Two additional lancet punctures will be performed after the exercise to measure the changes in neutrophil function: one immediately following the 30 minute exercise period and one 30 minutes after the exercise has been completed.
Caffeine Consumption
EXPERIMENTALParticipants will be exposed to a moderate dose of caffeine (200 mg capsule in one sitting) from a common commercial product. After consent and screening, a baseline blood sample will be acquired using the lancet puncture procedure. The participant will then be instructed to swallow a 200 mg caffeine capsule. Two additional lancet punctures will be performed after the caffeine ingestion: one after 30 minutes post-ingestion and another one after 60 minutes.
Ethanol Ingestion
EXPERIMENTALParticipants will be weighed and their required alcohol dose determined according to the equation used by the Madison Police Department during alcohol training workshops: 1 mL of 80 proof (40%) alcohol per pound of body weight. Participants will be permitted to consume the drink at their own pace, although no slower than one drink per hour. Breath Alcohol Concentration (BAC) will be tested 20 minutes after drinking has ceased in order to clear mouth alcohol that may affect the BAC reading. Participants at 0.05 BAC and above will have blood drawn via lancet puncture. In addition to the lancet puncture done once the alcohol level is reached, an additional lancet puncture will be performed 1 hour later.
Glucose Ingestion
EXPERIMENTALAfter a baseline blood sample is acquired, participants will consume 100 grams of glucose within 5 minutes. Two additional lancet punctures will be performed after the glucose ingestion, one at 30 minutes post-ingestion, and one at 60 minutes post-ingestion.
Glucose and Caffeine Ingestion
EXPERIMENTALAfter a baseline blood sample is acquired, participants will swallow 200mg of caffeine in capsule form and consume 100 grams of glucose within 5 minutes. Two additional lancet punctures will be performed after the caffeine and glucose ingestion, one at 30 minutes post-ingestion, and one at 60 minutes post-ingestion.
Interventions
Participants will ride a stationary bike and maintain their target heart rate (according to the American Heart Association guidelines) for 30 minutes.
Participants will swallow one ProLab caffeine 200mg tablet.
Participants will consume a dose of 80 proof alcohol according to their body weight to reach a breath alcohol concentration of 0.05.
Participants will consume 100 grams of glucose
Eligibility Criteria
You may qualify if:
- Capacity to provide informed consent and ability to speak and read English.
- Male or female with no chronic or acute health concerns that might affect subject safety during the study or interfere with the study results
You may not qualify if:
- In good physical health
- Regularly exercise at least 30 minutes 3 times per week (exercise cohort)
- Currently participating in another clinical trial
- History of significant systemic disease (eg. cancer, infection, hematological, renal, hepatic, coronary artery disease or other cardiovascular disease, endocrinologic, neurologic, rheumatologic, or gastrointestinal disease)
- Use of beta blockers or corticosteroids
- Currently taking medications that are not recommended to be taken in conjunction with alcohol
- Acute illness or evidence of clinically significant active infection
- Currently receiving immunotherapy
- Pregnant women
- Ingested medication (e.g. systemic corticosteroids) within 48 hours preceding the draw that the researchers believe may have an effect on immune response or the immune system
- Performed any activity that conflicts (eg. drinking any alcohol prior to the study), in the judgment of the investigator, with the external factor to be tested in the study (if any)
- Alcoholic or other health conditions for which alcohol consumption is contraindicated
- Consume more than 7 drinks per week (women alcohol cohort)
- Consume more than 14 drinks per week (men alcohol cohort)
- Consume more than three (8 oz.) servings of coffee, caffeinated soft drinks/tea (12 oz.) per day (caffeine cohort)
