Designing an experiment to determine the effectiveness of different electrolyte drinks on running performance requires careful planning. Here's a step-by-step guide to help you design a robust and reliable experiment:
1. Objective:

Clearly state the objective of the experiment. For instance: "To determine the effect of different electrolyte drinks on my running performance."
2. Variables:

Independent Variable: Type of electrolyte drink (e.g., Brand A, Brand B, Brand C, and a control like plain water).

Dependent Variable: Running performance (this can be measured in various ways like time taken to run a certain distance, perceived effort, heart rate, or recovery time post-run).

Controlled Variables: These are factors you want to remain constant, such as time of day you run, weather conditions (or running indoors on a treadmill), pre-run meal, amount of sleep the night before, and so on.

3. Procedure:

Baseline Measurement: Before starting the experiment, measure your average performance over multiple runs without consuming any electrolyte drink. This will give a baseline measure to compare with.

Randomization: To avoid order effects, randomize the order in which you test each drink.

Trial Period: Designate a period of time (e.g., a week) for each electrolyte drink. This will depend on the frequency of your runs and your recovery time. It's important to allow for enough recovery between runs to reduce fatigue bias.

Intake Protocol: Ensure you consume the same amount of the drink, and at the same time interval, before each run. For example, 500ml, 30 minutes before running.

Measurement: During each run, record:
The time taken to complete the run.
Heart rate (using a heart rate monitor) during the run and after the run (recovery heart rate).
Perceived effort using a scale (e.g., Rate of Perceived Exertion or RPE scale).
Any other factors that might be relevant, such as hydration post-run, muscle soreness, and overall feelings of recovery the next day.

Replication: To increase the reliability of your results, replicate the run for each drink multiple times. For example, three runs with Brand A, three with Brand B, etc.

Recovery and Rest: Ensure there's adequate rest between each run to reduce the impact of cumulative fatigue.

4. Data Analysis:

Once you've collected all your data, you can analyze the results to determine which drink had the best effect on your running performance. You can use:

Average and Median: For each performance metric, find the average and median across the different runs for each drink.

Variability: Measure the spread of the data, using standard deviation or variance.

Statistical Tests: Depending on the number of runs and data points, you might employ statistical tests like t-tests or ANOVAs to determine if there are significant differences between groups.

5. Conclusion:

Interpret the results and draw a conclusion on which electrolyte drink positively (or negatively) affected your running performance.
6. Limitations:

Acknowledge potential limitations in your experiment such as small sample size (if you only ran a few times for each drink), the placebo effect, or any uncontrolled variables.

By the end of this experiment, you should have a clearer understanding of how different electrolyte drinks impact your running performance. Remember to always consider individual responses, as what works best for you may differ from what works best for others.
