Fiber is not found in many of the processed foods Americans commonly eat — such as potato chips, pastries, and fried foods — and only five percent of Americans eat enough of it, a reason why it’s so popular in supplement form free roulette spielen. Studies have said that fiber supplements can improve overall and intestinal health, but the researchers point out that the fiber you’re getting in pill or powder form won’t be as efficient as the fiber found in food.

Studies have not adequately assessed the safety of citrulline, particularly when users take it in supplemental form for months at a time. In the study of weight lifters described above, 6 of the 41 participants reported stomach discomfort after taking the supplement . Additional short-term studies in which supplemental citrulline was provided to nonathletes at up to 6 g/day for 4 weeks and 1.35 g/day for 6 weeks found no adverse effects .
Much of the limited research on use of tart cherry to enhance exercise and athletic performance involves short-term use of a tart-cherry product or placebo by young resistance-trained men for about a week before a test of strength (such as single-leg extensions or back squats); participants continue taking the supplements for about 2 days after the test. Study results vary, but the benefits appear to include more rapid recovery of strength and/or lower perceived muscle soreness . One pilot study investigated the use of tart-cherry juice (472 ml/day; the equivalent of 100–120 whole cherries) or a placebo for a week before a marathon and 2 days afterward in 13 male and 7 female runners (age range 24–50 years) . None of the participants who drank the juice experienced airway inflammation causing upper respiratory tract symptoms after the marathon (a common complaint in many marathon runners), but half of those drinking the placebo did. Another study compared a supplement containing 480 mg freeze-dried Montmorency tart-cherry-skin powder (CherryPURE) with a placebo in 18 male and 9 female endurance-trained runners and triathletes (age range 18–26 years) . Participants took the supplements once a day for 10 days, including the day they ran a half-marathon, then for 2 days after the run. Participants taking the tart-cherry supplement averaged a statistically significant 13% shorter race finish time and had lower levels of blood markers of inflammation and muscle catabolism than the placebo takers, but perceptions of soreness of the quadriceps muscles did not differ significantly between the groups.

Using the criteria of leucine content, Norton and Wilson et al. used animal models to compare the potential to activate initiation factors and MPS between four different protein sources: wheat (supplemented with leucine), soy, egg, and whey, (containing 6.8, 8.0, 8.8, and 11% leucine, respectively) using a diet consisting of three meals per day. Macronutrient intake was 16/54/30% for protein, carbohydrates and fat, respectively. Wheat and soy did not stimulate MPS above fasted levels, whereas egg and whey proteins significantly increased MPS rates, with MPS for whey protein being greater than egg protein. MPS responses were closely related to changes in plasma leucine and phosphorylation of 4E–BP1 and S6 K protein signaling molecules. More importantly, following 2- and 11-weeks of ingestion, it was demonstrated that the leucine content of the meals increased muscle mass and was inversely correlated with body fat.
The logical next step for researchers is to extend these findings into longitudinal training studies to see if these patterns can significantly affect resistance-training adaptations. Indeed, published studies by Arnal and Tinsley have all made some attempt to examine the impact of adjusting the pattern of protein consumption across the day in combination with various forms of exercise. Collective results from these studies are mixed. Thus, future studies in young adults should be designed to compare a balanced vs. skewed distribution pattern of daily protein intake on the daytime stimulation of MPS (under resting and post-exercise conditions) and training-induced changes in muscle mass, while taking into consideration the established optimal dose of protein contained in a single serving for young adults. Without more conclusive evidence spanning several weeks, it seems pragmatic to recommend the consumption of at least 20-25 g of protein (~0.25 g/kg/meal) with each main meal with no more than 3–4 h between meals .

This guide to eating healthy on a budget can be a useful resource, but if you’re a coach who’s working with an athlete, it can also help to understand the problems presented by “food deserts” and “food insecurity.”)
This isn’t the most exciting topic, but it’s incredibly important. That’s because if you don’t drink enough water—and become dehydrated as a result—your health will decline, your metabolic rate will slow, and your athletic performance will tank.12
Protein, carbs, and fat are known as macronutrients, or macros, and they’re key to nailing the essentials of sports nutrition. Getting the right amounts of each macronutrient ensures you’ll have the energy and raw materials you need to perform your best and get the results you want.
Athletes need more protein than non-athletes. That’s because protein is necessary to repair the muscle damage caused by hard-training and intense competitions. When athletes don’t eat enough of this nutrient, it’s harder to build muscle, lose fat, and recover from practices, workouts, and games.
At Elite Sport Nutrition, we provide top-tier nutrition consulting for both professional and amateur athletes. Our personalized meal plans and supplement consultations are tailored to meet your specific needs and support your training goals.
