The Effects of Antioxidant Supplementation on Multiple Endurance Race Performance, Physiology, and Recovery.
Study Details
Study Description
Brief Summary
Thirty active male and female athletes will be recruited for the study. Subjects will be examined at baseline for VO2max performance. Subjects will then be stratified and randomly divided equally (50% - 50%) into an Oceanix (supplemental) or placebo condition such that baseline VO2max match. Once randomization, subjects will be baseline tested for multiple measures of muscle force capacity, muscle soreness, immune function, and endocrine function. Upon completion of baseline testing, subjects will all complete a one-day, cross-training course in Tampa, Florida. The training course is known to be extremely vigorous and causes significant muscle damage. Subjects will then be retested for muscle function at 24, and 48 hours following the course. At 24- and 48-hours subjects will be asked to repeat a simulated time trial race. In this way, we will measure repeated race performance, recovery from intense exercise, muscle damage from exercise, and immune function during multiple races.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Placebo Comparator: Placebo Group Participants will engage in a one day, whole-body, cross-training course while consuming a visually identical placebo (25mg hydroxypropyl methylcellulose) 30 minutes prior to exercise on training days or with the first meal of the day on non-training days. Participants will then come in 24 and 48 hours post, cross-training course to be tested. |
Other: Cross Training Course
One day of a supervised, whole body, cross-training course that is meant to produce muscle damage and soreness.
|
| Experimental: Experimental Group Participants will engage in a one day, whole-body, cross-training course while consuming the treatment condition (Oceanix™) 30 minutes prior to exercise on training days or with the first meal of the day on non-training days. Participants will then come in 24 and 48 hours post, cross-training course to be tested. |
Other: Cross Training Course
One day of a supervised, whole body, cross-training course that is meant to produce muscle damage and soreness.
Dietary Supplement: Oceanix
Ingredient contains highly active antioxidant enzymes, including superoxide dismutase (SOD), as well as essential fatty acids, vitamins, amino acids and minerals.

Outcome Measures
Primary Outcome Measures
- Changes in muscle strength [Baseline, 24-Hour Post Cross-Training Course, 48-Hours Post Cross-Training Course.]
Assessed by isometric mid-thigh pull.
- Changes in muscle power [Baseline, 24-Hour Post Cross-Training Course, 48-Hours Post Cross-Training Course.]
Assessed through ground reaction forces during countermovement and squat jumps on a force plate.
- Changes in One(1) Mile Timed Run [Baseline, 24-Hour Post Cross-Training Course, 48-Hours Post Cross-Training Course.]
Experimental outcome assessing how quickly a 1 mile run can be completed.
- Changes in Perceived Recovery Status (PRS) [Baseline, 1 Day of Cross-Training Course, 24-Hour Post Cross-Training Course, 48-Hours Post Cross-Training Course.]
Assessed through a visual analog scale (modified Borg Scale) numbered 0 to 10 with visual descriptors.
- Changes in Rating of Perceived Exertion (RPE) [Baseline, 1 Day of Cross-Training Course, 24-Hour Post Cross-Training Course, 48-Hours Post Cross-Training Course.]
Assessed through a visual analog scale numbered 0 to 10 with visual descriptors.
- Changes in Perceived Soreness Scale [Baseline, 1 Day of Cross-Training Course, 24-Hour Post Cross-Training Course, 48-Hours Post Cross-Training Course.]
Assessed through a visual analog scale numbered 0 to 10 with visual descriptors.
Secondary Outcome Measures
- Creatine Kinase [Baseline, 24-Hour Post Cross-Training Course, 48-Hours Post Cross-Training Course.]
Experimental outcome examining creatine kinase in fasted whole blood samples. This is biomarker an indirect measure of muscle damage.
- Cortisol [Baseline, 24-Hour Post Cross-Training Course, 48-Hours Post Cross-Training Course.]
Experimental outcome examining the concentration of cortisol in fasted saliva samples.
Other Outcome Measures
- VO2max [Baseline]
Assessment of VO2max to determine fitness level and use as basis for randomization.
