The aim of this study was to investigate if the supplementation with Opuntia ficus-indica (OFI) juice may affect plasma redox balance and heart rate variability (HRV) parameters following a maximal effort test, i…

Endurance athletes typically consume carbohydrate-rich diets to allow for optimal performance during competitions and intense training. However, acute exercise studies have revealed that training or recovery w…
The results of this event showed that the consumers of the service were interested in food allergy/intolerance issues. Most athletes seeking nutritional advice had no previous nutritional support (86.5%) and wanted nutritional plans and performance-related advice (81.1%).
When a high-carbohydrate diet is ingested, whether as small frequent snacks or as large meals, there is no difference between the two with respect to post-exercise glycogen storage for a period of 24 h. Howeve…
Exercise increases skeletal muscle reactive oxygen species (ROS) production, which may contribute to the onset of muscular fatigue and impair athletic performance. Mitochondria-targeted antioxidants such as Mi…
Homeostatic mechanisms related to the balance of fats, carbohydrates, and proteins are thought to help regulate eating behavior and energy balance . Increased energy and macronutrient intake after exercise may be related to substrate oxidation, so athletes are more likely to consume foods high in carbohydrates, post-workout, to restore carbohydrate balance . However, this is not always observed in scientific research, as there are differences potentially associated with the design of the experiment and the population being studied . Much of the research on macronutrient regulatory systems relates to energy intake and obesity . Much of the research on macronutrient regulatory systems relates to energy intake and obesity. The results may apply differently to populations of athletes wherein carbohydrate intake during exercise is common practice and wherein training adaptations may affect product use .

For those attempting to increase their calories, we suggest consuming small snacks between meals consisting of both a complete protein and a carbohydrate source. This contention is supported by research from Paddon-Jones et al. that used a 28-day bed rest model. These researchers compared three 850-cal mixed macronutrient meals to three 850-cal meals combined with three 180-cal amino acid-carbohydrate snacks between meals. Results demonstrated that subjects, who also consumed the small snacks, experienced a 23% increase in muscle protein fractional synthesis and successful maintenance of strength throughout the bed rest trial. Additionally, using a protein distribution pattern of 20–25 g doses every three hours in response to a single bout of lower body resistance exercise appears to promote the greatest increase in MPS rates and phosphorylation of key intramuscular proteins linked to muscle hypertrophy . Finally, in a series of experiments, Arciero and colleagues employed a protein pacing strategy involving equitable distribution of effective doses of protein (4–6 meals/day of 20–40 g per meal) alone and combined with multicomponent exercise training. Using this approach, their results consistently demonstrate positive changes in body composition and physical performance outcomes in both lean and overweight/obese populations . This simple addition could provide benefits for individuals looking to increase muscle mass and improve body composition in general while also striving to maintain or improve health and performance.
Recommendations regarding the optimal protein intake per serving for athletes to maximize MPS are mixed and are dependent upon age and recent resistance exercise stimuli. General recommendations are 0.25 g of a high-quality protein per kg of body weight, or an absolute dose of 20–40 g.
