Brief summary
Strength training is commonly used as an intervention to increase muscle mass, thus improving a person's ability to undertake activities of daily living, or enhance athletic performance. The strength training regimen itself, while ultimately having beneficial effects, causes muscle fibers to be damaged, which the body has to recover from. As the body recovers, it rebuilds the muscle tissue and after multiple consecutive bouts of strength training, the muscle eventually becomes larger and stronger. Thus, it is the recovery from strength training exercise that ultimately determines how well the body adapts. Where inadequate recovery could eventually lead to overtraining and/or injury, optimizing the recovery process from strength training could maximize strength training adaptations. This concept of optimizing recovery has led to development of many supplements, including antioxidants, which may reduce the damage associated with strength training activities and therefore enhance positive adaptations. The purpose of this study is to assess the ability of a polyphenol rich supplementation to aid the recovery process from a demanding bout of resistance exercise

Masking description
To ensure that all subjects and researchers are unaware of the treatment assignments we will have one outside individual that will possess the knowledge of which subjects are given which supplement and which were given a placebo. This information will remain confidential until the study has been concluded. At the conclusion of the study, participants will be informed of which condition they were assigned. in an event of an emergency or the participant decides not to participate his condition will be revealed.
Intervention model description
20 male participants will start with a familiarization visit where they will receive either the placebo supplement or the polyphenol rich supplement that they will take for 7 days. After taking the supplement, the participants will come back and run through the acute resistance exercise protocol as well as return the next day for a post test. Next, the participants will undergo a wash out phase where they will not take any supplementation. At the end of these 2 weeks, the participants will then take the other supplement (i.e. if they took the polyphenol rich supplement in the first phase they will take the placebo supplement in the second phase). After a week of taking their assigned supplement, participants will complete the acute resistance exercise protocol and the post test.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of Oxidative Stress | 7 weeks | Blood analyses will be used, 8 mL of blood will be taken from the participant six times per condition. The blood will be centrifuged to separate the serum/ plasma and analyzed by enzyme- linked immunosorbent assay (ELISA) for c- reactive protein and creatine kinase, and oxidative damage |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Muscle soreness | 7 weeks | Subjects will mark a line on a 10cm scale that corresponds to the amount of muscular soreness they currently perceive |
| Vertical Jump Performance | 7 weeks | Subjects will be instructed to stand on a NeuroCom Balance Manager forceplate with hands on hips. Subjects will then be instructed to perform 3 consecutive vertical jumps, as high as possible with minimal time between jumps. The jumps will later be assessed for power production. |
