What is empirical evidence?

Empirical evidence is defined as information that is acquired through direct observation, experimentation, or practical experience. This type of evidence is essential in scientific research as it allows for the validation of theories and hypotheses through measurable and observable data.

When researchers conduct experiments, they collect data that can be analyzed and repeated, which strengthens the reliability of their findings. This is opposed to relying solely on personal anecdotes or theoretical concepts that may not have been tested in real-world scenarios. Empirical evidence forms the basis of scientific knowledge because it is grounded in observable phenomena, making it critical for drawing valid conclusions in various fields, including sports nutrition. By emphasizing experimentation and observation, empirical evidence enables practitioners to make informed recommendations based on what has been demonstrated to work in practice.
