Protein and Athletic Performance
For an athlete, the primary role of dietary proteins is for use in the various anabolic processes of the body. As a result, nutritionists, trainers, and strength/endurance coaches are all keyed in on to the protein requirements created by high intensity training. Research has shown that if more protein or amino acids were available to the exercising muscle it would enhance protein synthesis. NutrePRO’s protein components (1) Bioactive Collagen Peptide fortified with Tryptophan and BCAA’s (branch chain amino acids) & (2) Whey Protein Isolate are COMPLETE proteins. Each protein on its own contains every essential amino acid required by the body on-a-daily-basis. It is important to note that many products marketed to athletes contain ONLY Whey Isolate or other Whey products. Without the 2nd bioactive peptide protein base contained in NutrePRO, athletes lose a very significant and imperative advantage set needed to maximize an athlete’s performance and strength. That set includes the body’s ability to repair, rebuild, recover, and grow.
“Research has tended to support this hypothesis. Within four weeks of protein supplementation (3.3 versus 1.3 g·kg-1·day-1) in subjects’ resistance training, significantly greater gains were seen in protein synthesis and body mass in the group of subjects with the greater protein intake (Fern et al., 1991). Similarly, Lemon et al. (1992) also reported a greater protein synthesis in novice resistance trained individuals with protein intakes of 2.62 versus 0.99 g·kg-1·day-1. In studies examining strength-trained individuals, higher protein intakes have generally been shown to have a positive effect on muscle protein synthesis and size gains (Lemon, 1995; Walberg et al., 1988). Tarnapolsky and colleagues (1992) have shown that for strength trained individuals to maintain a positive nitrogen balance they need to consume a protein intake equivalent to 1.8 g·kg-1·day-1. This is consistent with other studies showing that protein intakes between 1.4 – 2.4 g·kg-1·day-1 will maintain a positive nitrogen balance in resistance trained athletes (Lemon, 1995). As a result, recommendations for strength/power athletes’ protein intake are generally suggested to be between 1.4 - 1.8 g·kg-1·day-1.
Similarly, to prevent significant losses in lean tissue endurance athletes also appear to require a greater protein consumption (Lemon, 1995). Although the goal for endurance athletes is not necessarily to maximize muscle size and strength, loss of lean tissue can have a significant detrimental effect on endurance performance. Therefore, these athletes need to maintain muscle mass to ensure adequate performance. Several studies have determined that protein intake for endurance athletes should be between 1.2 – 1.4 g·kg-1·day-1 to ensure a positive nitrogen balance (Freidman and Lemon, 1989; Lemon, 1995; Meredith et al., 1989; Tarnopolsky et al., 1988). Evidence is clear that athletes do benefit from increased protein intake.”—Excerpt reference information available at the bottom of the page.
Why NutrePRO’s Dual Protein blend is better than the Whey-only protein options
During and after long periods of exercise, protein loss can occur in the muscles as their structural integrity is compromised by oxidation, membrane microlesions, and inflammatory reactions. NutrePRO, when compared to other whey-only protein options, contains 15X the amount of Glycine. Glycine is the precursor to Creatine, which NutrePRO is widely known as the premier substance in building muscle mass and enhancing muscle and fitness recovery. A diet with NutrePRO as a protein source before exercise and/or just after exercise enhances muscle anabolism, replacing lost proteins and helping to maintain and restore the protein content of the muscles while also reducing recovery time.
AIDING MUSCULAR CONTRACTION
Muscular function is dependent on the energy produced by the breakdown of a compound called adenosine triphosphate (ATP) in cells. Creatine is a molecule consisting of three amino acids – glycine, arginine and methionine – that aid muscular contraction during periods of high intensity exercise and help to replace depleted ATP levels. NutrePRO contains 15X the amount of Glycine and 4X the amount of Arginine when compared to whey-only protein sources. With its high levels of glycine and arginine, NutrePRO supports the synthesis of creatine in the body to improve muscle contraction performance during short bursts of exercise helping athletes increase their lean muscle body mass.
IMPROVING ATHLETIC PERFORMANCE
A daily recommended dose of 100g of NutrePRO generates significant levels of Arginine per day. Studies show that 1g supplements of Arginine taken five days per week for five weeks increases strength. Arginine stimulates the release of growth hormone from the pituitary gland, which in part explains athletic performance improvement.
ATHLETES- PROTECTING JOINTS AND CONNECTIVE TISSUES
Athletics and fitness such as running and cycling, or lifting weights or playing football, often involve repetitive, high impact movements that can lead to damage to cartilage, tendons and ligaments and result in excess stress on joints. Research has shown that bioactive collagen peptides help protect the joint matrix and the connective tissues. Collagen peptides support connective tissues and limit discomfort as well as the risk of any joint related injury, by increasing the production of cartilage matrix. NutrePRO’s proprietary amino acid mix is readily absorbed into the body and distributed to joint and cartilage sites.
A large-scale study following three different categories of athletes demonstrated that a supplementation with a mix of collagen peptides, BCAAs and Arginine over a period of two years decreased the injury rate for tendon-ligaments, joints and muscle. These studies were conducted using OUR specific type of bioactive collagen peptide protein base.
Joint cartilage requires sulfur for its formation. The essential amino acid in NutrePRO- Methionine facilitates Sulphur compounds in the body, especially when combined with B vitamins. The more Sulphur you have, the less joint degeneration happens and the more joint protection and recovery ability you have
NutrePRO’s bioactive peptide collagen base helps to protect, repair and rebuild cartilage, joints and tendons, it reduces joint discomfort, and reduces joint inflammation.
