Supplement consumption profile by strength training practitioners in Brazil: a literature review

Abstract

The search for muscle hypertrophy and health improvements has increased both the number of exercisers and the consumption of supplements. The correct use is able to delay muscle fatigue and improve sports performance. However, inadequate supplementation can cause several health problems, so it is necessary to seek a qualified professional for indication of use. The present literature review objective to evaluate the profile of supplement consumption in gyms in different cities and states in Brazil. The research was carried out through a literature review, within the criteria established by the PRISMA Statement. The following databases were used: PubMed, Google Scholar and SciELO, integrating only studies about the use of dietary supplements by strength training practitioners in Brazil, using 25 scientific articles, published between 2011 and 2021. The results shows that the most cited objective for use of supplementation was for muscle hypertrophy, where the most used supplements was whey protein. Another relevant result was the lack of indication of a suitable professional, such as a nutritionist, for consumption recommendation. On the other hand, the main sources of indication were Physical Education professionals, followed by friends and self-referral, which can result in inadequate consumption and, consequently, bring health risks.

The effect of dietary supplements on frailty in older persons: a meta-analysis and systematic review of randomized controlled trials

“…A diet rich in protein benefits health, aids in the recovery of sick people, and maintains functional status in elderly people (Prokopidis et al, 2022a). An efficient method for improving muscle growth and strength as well as overall physical performance in older persons is the combination of resistance training and post-exercise protein supplementation (Khor et al, 2022;Velasco et al, 2022). Vitamin D intake is critical for older adults because of its widely recognized links to bone health, muscle strength and function (Li et al, 2022;Prokopidis et al, 2022b;Wang et al, 2022).…”

Effect of milk protein concentrate supplementation on body composition and biochemical markers during a resistance training program

“…Supplements help complement the diet of a person and are ergogenic resources used to improve performance in sports and fitness activities (Moreira et al, 2013) The popularity of supplements is directly linked to people seeking healthy and nutritious food options that help improve physical fitness (Cavalheiro et al, 2020). The supplements most consumed by RT practitioners are protein supplements, particularly albumin and whey proteins (WP) (Velasco et al, 2022), obtained after the removal of casein from milk, and contain a large amount of amino acids, calcium, and bioactive whey peptides (Alves & Lima, 2009). Proteins from milk whey are rapidly digested and absorbed rapidly increasing plasma amino acid levels after ingestion; whereas casein is slowly absorbed, and decreases the stimulus of protein synthesis after ingestion (Souza et al, 2015).…”
