Effects of microalgae extract supplementation on muscle recovery and endurance capacity

Effects of microalgae extract supplementation on muscle recovery and endurance capacity

The purpose of this investigation is to examine the effects of consuming a new dietary microalgae supplement, (3 different dosages) versus a placebo (containing maltodextrin, a type of sugar). Different types of microalgae are commonly used as dietary supplements intended to improve health and exercise outcomes. For example, astaxanthin, chlorella, and spirulina are forms of microalgae sometimes marketed to potentially enhance exercise performance and recovery.

We will specifically be examining muscle function, energy utilization, muscle soreness and swelling, daily wellness perception, and differences in exercise-induced muscle damage and inflammation in before and after an exercise-induced muscle damage protocol (downhill running). We will also be evaluating the influence of this dietary supplement on endurance capacity following extended duration consumption.

This study will take approximately 8 weeks. There will be 8 visits total. The first visit will take about 30 minutes and each subsequent visit will take approximately 60 minutes to complete with the exception of visit 5 that will take approximately 2.5 hours. During the 8 weeks, participants will complete different surveys, exercise tests, have body measurements taken, complete daily food logs, consume a dietary supplement or placebo, and have blood draws performed.

Inclusion Qualifications:

  • Are a recreationally active man (i.e. participating in moderate aerobic physical activity for a minimum of 30 minutes on five days per week OR vigorous aerobic activity for a minimum of 20 minutes on three days per week)
  • Are between the ages of 18-35 years old
  • Have no physical limitations preventing running, countermovement jump (jumping upwards in place), and strength assessments
  • Healthy as determined by the PAR-Q+ and Health History Questionnaire

Exclusion Qualifications:

You may not participate in this research opportunity if any of the following applies to you:
  • Untrained
  • Any response of “yes” on the PAR-Q+
  • Physical limitations preventing running, countermovement jump, and strength (peak isometric torque and peak isokinetic torque) assessments
