Background and study aims
The human gut plays host to tens of trillions of different bacteria, which are known as the “gut flora”. The bacteria present in the gut flora are often referred to as “good” or “friendly” bacteria, because they assist in digestion and help to produce important vitamins for the body. Probiotics, which usually come in the form of supplements or drinks, are live bacteria which are promoted as being extremely beneficial for health, as they are thought to replenish levels of “good bacteria” in the gut. Many studies have shown that probiotic supplements can help to support a healthy digestive and immune system. It has also been shown that probiotics can help to increase the amounts of essential nutrients, such as proteins, that are absorbed in the gut. An initial study has shown that consuming probiotics and protein together can help improve performance in athletes during resistance training (weight training). It is well established that protein can help to prevent and repair muscle damage following exercise, and this study aims to find out whether consuming protein and probiotics together can help to speed up muscle recovery and reduce muscle damage following a damaging exercise bout, as well as boosting athletic performance.
Who can participate?
Healthy men between 18 and 25 years of age, who take part in sports recreationally (not professionally).
What does the study involve?
At the start of the study, each participant is given time to get used to the different exercises that are used in the study. All participants are then asked to consume 20g casein (protein found in milk products) every day for two weeks. They then complete a bout of potentially muscle-damaging exercise. Markers of muscle damage, recovery and athletic performance are then measured at 24 hour intervals over 72 hours. After a one week break, participants then consume 20g casein as well as the pro-biotic (GanedenBC30) every day for two weeks, after which the exercises and measurements are repeated, at 24 hour intervals over 72 hours.
What are the possible benefits and risks of participating?
A benefit of participating is that the results of this study will provide athletes with a nutritional alternative to reduce the negative effects of training. Possible risks include pain during the collection of the blood sample and injury during the exercise.
Where is the study run from?
Department of Health Sciences and Human Performance, University of Tampa, Florida (USA)
When is the study starting and how long is it expected to run for?
July 2014 to May 2015
Who is funding the study?
Ganeden Biotech Inc. (USA)

| Scientific title | Effects of co-administration of probiotic (Bacillus coagulans GBI-30, 6086) and protein (Casein) on markers of skeletal muscle damage, perceived recovery and athletic performance after an intense single leg training bout |
| Study objectives | To determine if the co-administration of GanedenBC30 with protein has a beneficial effect on muscle damage, recovery and athletic performance following a damaging exercise bout. |
| Ethics approval(s) | The University of Florida Tampa institutional review board committee, 21/08/2014, ref: 18-25 |
| Health condition(s) or problem(s) studied | Probiotic supplementation |
| Intervention | Healthy, recreationally trained male athletes consume 20g of casein (Control = CON) for 2 weeks (days 1-14), followed by a muscle-damaging exercise bout on day 15, perceptual measures on day 16 (24 hours post exercise), perceptual, muscle damage and performance measures on day 17 (48 hours post exercise), and perceptual measures on day 18 (72 hours post exercise). Following a one-week wash-out period (days 19-24), the athletes consume 20g of casein plus 1 billion CFU Bacillus coagulans GBI-30, 6086 (GanedenBC30; Ganeden Biotech Inc., Maryfield Heights, OH) for two weeks (days 25-38). A muscle-damaging exercise bout is then performed on day 39, perceptual measures on day 40 (24 hours post exercise), perceptual, muscle damage and performance measures on day 41 (48 hours post exercise), and perceptual measures on day 42 (72 hours post exercise). Both supplemental conditions are identical in appearance, taste, and weight. |

| Primary outcome measure | 1. Perceptual measures of recovery [muscle soreness and perceived recovery] will be assessed using the visual analogue scale [VAS]. 2. Markers of muscle damage determined: 2.1. Blood Creatine Kinase (CK) 2.2. Blood Urea Nitrogen (BUN) 2.3. Muscle Swelling (MS) will be assessed via two-dimensional, B-mode ultrasonography (GE, LoGIQ e) to determine muscle thickness of the vastus lateralis (VL) 3. Athletic Performance: 3.1. Single-Leg 1RM (1RM): will be assessed via one repetition maximum testing (1RM) in the one-legged leg press. Three maximal attempts will be allotted with the greatest 1 RM counting for final data. 3.2. Single-Leg Vertical Jump Peak Power (VJPP): will be assessed via maximal vertical jump peak power bout using a Tendo Unit (Trencin, Slovak Republic). Three maximal attempts will be allotted with the greatest peak power counting for final data. Participants will 60 seconds between vertical jump attempts. 3.3. Wingate Peak Power (WPP): will be assessed via Monark Wingate cycle ergometry (Monark™, Vansbro, Sweden). During the cycling test, the volunteer will be instructed to cycle against a predetermined resistance (7.5% of body mass) as fast as possible for 10 seconds. |
