    I have to plan out and conduct an experiment for one of my physiology classes. This is the list of equipment I have to play with..

    * eMac computers and PowerLab units (Multifunction)
    * Respiratory Pods for PowerLab (Ventilation, pulmonary volumes and capacities)
    * Bell Spirometer (Ventilation, pulmonary volumes and capacities)
    * Metabolic Analyzer system for PowerLab (Measure VO2, VCO2, RER, Energy Expenditure, Efficiency, Economy)
    * Douglas bags and O2 & CO2 analyzers (Measure VO2, VCO2, RER, Energy Expenditure, Efficiency, Economy)
    * Electrocardiogram (ECG, PowerLab) (Heart rate)
    * Pulse oximeter (PowerLab) (Arterial oxyhemoglobin saturation)
    * Electromyogram (EMG, PowerLab) (Activation of muscle)
    * Stethoscopes (Heart sounds, blood pressure)
    * Heart rate monitors (Heart rate)
    * Blood pressure cuffs (Blood pressure)
    * Stairmaster (Manipulate speed, rate of climbing)
    * Treadmill (Manipulate speed, grade)
    * Monark Cycle Ergometers (stationary bikes) (Manipulate resistance, timed-trials, wingate anaerobic tests)
    * Handgrip dynamometer (PowerLab) (Manipulate forearm muscle contractions)
    * Biodex dynamometer (Manipulate resistance, speed of knee extension) NOTE: Use of the Biodex requires some training, so check with your GTF if you think you might want to use this system.
    * Borg Scale (Rating perceived exertion)

    I can think of a ton of ideas but thought maybe someone might be curious about something..example: which abdominal exercise activates the most muscles...which exercise targets the rear delts the most...stuff like that. Options are endless.

    Maine + Test and Anavar = PL Greatness



    Please proceed accordingly

    Energy expenditure during the exercise of those who had a pre-workout drink vs those who haven't.

    Benifits for athletes of stopping all alcohol consumption or drinking very little?

    could do something along those lines...have the dependent be the time consumed before exercising or the nutritional value?

    The depend variable would be energy expenditure. I would use the pre-workout drink and drink timing that Tipton used in his lastest article and I wouldn't play with those. But it's not my project, it's yours ! It's just that Tipton studied drink timing and composition and its effects on lean mass gain, but I don't recall seeing something on the influence of a drink on energy expenditure during exercise (although it has been done a lot on exercise performance, fatigue and so on).

    We could hypothesize that the drink would enhance performance and be beneficial in the long term but when comparing the same amount of work, I'd be curious to see its effects. Maybe something has been done when they worked on the respiratory quotient and fuel partitioning though.

    Can you link me or pm Tipton's article?

    sounds good...would be really easy to set up. I'll run it by my lab partner tomorrow.

    You could compare it to a normal isocaloric carbohydrate solution too. I know the respiratory quotients won't probably be the same but I'm not sure about what it'll do to energy expenditure. Maybe there would be differences between regular cardio and intermittent training.
    Please, use a regression analysis ! Other tests suck.
    This guy is pretty awesome when it comes to stats, you could maybe ask him some suggestions : http://evidencebasedfitness.blogspot.com/
