Background. Competitive sport has the potential for high levels of stress and anxiety that may affect performance and increase the risk of injuries. While benefits of pre-training assumption of N-3 polyunsaturated fatty acids are well known, poor data are available on Schisandra chinensis. Schisandra chinensis is a medicinal plant in use in Chinese medicine which increases physical working capacity and affords a stress protective effect.
Objectives. We tested, in an open pilot study, the effect on competition related stress, anxiety and self-confidence of a novel formulation containing: PUFAs, Schisandra chinensis extract and vitamin D3.
Methods. A novel formulation containing N-3 polyunsaturated fatty acids (PUFAs), Schisandra chinensis extract and vitamin D3, five ml per day was administered to one group of fifteen elite sport athletes (basketball players). Competitive State Anxiety Inventory-2 (CSAI-2) tests were administered at baseline and after 3 months.
Results. All subjects completed the 3 months period of the study, all declaring a consumption >75% of daily recommended dose. No adverse event were registered. After intervention, the median cognitive state anxiety score remained mild (score 16) even if with an overall statistically significative decrease (p=0.005); same results were registered after intervention for the somatic state anxiety score (score 16) with an overall statistically significative decrease (p=0.008) and for the self-confidence score (score 22, range 15-30) with an overall statistically significative increase (p=0.008).
Conclusion. The results showed the positive effect of the treatment on the control of stress and anxiety and the improvement of self-confidence in a large majority of the subject enrolled. However, further studies are needed to confirm our findings.

The Effect of Supplementing a Novel n-3 Polyunsaturated Fatty Acids Formulation Containing Schisandra chinensis Extract and Vitamin D3 to a Group of Elite Sport Athletes on Competition Related Stress, Anxiety and Self-confidence 1Andrea Belluzzi*, 2Peter Lembke, 1Giovanni Marasco, 1Eleonora Scaioli 1Department of Medical and Surgical Sciences, Sant’Orsola-Malpighi Hospital, Bologna, Italy.
We tested, in an open pilot study, the effect on competition related stress, anxiety and self-confidence of a novel formulation containing: PUFAs, Schisandra chinensis extract and vitamin D3.
A novel formulation containing N-3 polyunsaturated fatty acids (PUFAs), Schisandra chinensis extract and vitamin D3, five ml per day was administered to one group of fifteen elite sport athletes (basketball players).
In this pilot open study we intended to test the effect of n-3 PUFAS, Schisandra and Vitamin D3 enriched preparation in a liquid form as supplement on cognitive state anxiety, somatic state anxiety and self-confidence defined accordingly to Competitive State Anxiety Inventory-2 (CSAI-2) test (12) that is one of the most frequently used and validated instruments when assessing competitive state anxiety in sport psychology research (13).
DISCUSSION This open pilot study shows the positive effect of a mixture of n-3 PUFAs, Schisandra chinensis plant extract and Vitamin D3 on the control of stress and anxiety in a group of elite competing basketball players.
CONCLUSION In conclusion, the preliminary results of this open pilot study showed a significant improvement on cognitive state anxiety, somatic state anxiety and self-confidence in a group of elite competing basketball players supplemented with a combination of n-3 PUFAs with Schisandra chinensis plant extract and Vitamin D3.
