Effects of protein supplementation in fitness world: A 12-week cross-over studio

Abstract

The aim of this project was to evaluate the effect of isolated protein supplementation in young amateur athletes. Sixteen subjects aged between 20 and 30 were recruited for this study. Before to start sports performance was assessed at T0, in all subjects, using physical performance test and evaluated body composition. Therefore, the subjects were randomly assigned in two groups (group A and B) of 8 subjects each. The group A start to intake 30 g of protein powder diluted in water after each training session (3 times a week) for six weeks (T0) whilst the group B was the placebo. After 6 weeks (T1), the measurement were repeated for all subjects and the group A became placebo and the group B started with the supplementation. At the end of 6 weeks (T2) we carried out all the tests were performed again. Results showed a significant improvement in almost all tests between T0 and T2 within the same group (p < .05), but not significant difference was found between the start and the end of protein's intake period in both groups. In conclusion, supplementation did not have affect the performance and body composition significantly. Instead, training seems to influence the performance more the supplementation.

The Impact of Diet and Physical Activity on Bone Health in Children and Adolescents

“…There are several studies that have investigated in adulthood the best strategies in order to maintain good lean mass and bone mass by modification of diet and physical activity (125)(126)(127)(128)(129)(130). Most of the adult studies have focused on osteoporosis risk subjects, postmenopausal women, and have analyzed the effect of minerals (mainly calcium), vitamin supplementation (mainly vitamin D), and nutrients, especially protein supplementation (131).…”

Iodine Biofortification and Seaweed Extract-Based Biostimulant Supply Interactively Drive the Yield, Quality, and Functional Traits in Strawberry Fruits

“…Modern consumers increasingly require food containing high amounts of macro- and micronutrients [ 1 , 42 , 43 ]. This need is linked to the lack of essential elements in human diets [ 23 , 44 , 45 ]. As a consequence, biofortification is recognized as a useful tool to enhance the concentration of trace elements, such as I [ 19 , 28 , 30 ], zinc [ 23 , 46 , 47 ], selenium [ 48 , 49 , 50 , 51 ], manganese [ 52 , 53 , 54 ], molybdenum [ 14 , 55 , 56 , 57 , 58 ], iron [ 59 , 60 , 61 ], and bioactive compounds in fruits and vegetables.…”

The Role of Consumption of Molybdenum Biofortified Crops in Bone Homeostasis and Healthy Aging

“…Micronutrient needs for optimizing well-being in theory can be met by a healthy diet. However, most of the population does not have such a diet, especially during times when their well-being is challenged [ 3 , 7 , 9 , 10 , 11 ]. Among different agronomic practices [ 12 , 13 , 14 ], agronomic biofortification is recognized as one of the most promising, efficient, sustainable and cost-effective strategies for overcoming mineral malnutrition [ 15 , 16 , 17 , 18 , 19 , 20 ].…”
