Background. Blood flow restriction (BFR) training is gaining increasing attention in the scientific community. Studies using exercise combined with blood flow restriction have shown muscle strength and size improvement. In fact, the main feature of BFR training is that can elicit muscle hypertrophy and strength adaptations using light external loads (20-30% one repetition maximum, 1RM) comparable to what is typically seen following high-load (HL) training programs with 70-85% 1RM. This specific training has applications for individuals who may not be able to tolerate the mechanical stresses associated with higher loads, such as the elderly or injured; thus, several investigations have focused on implementing BFR exercise within older and clinical populations. However, the effects of this kind of technique in healthy athletes are not clear in scientific literature. The purpose of this study is to conduct a systematic review with meta-analysis to evaluate the qualitative and quantitative results of blood flow restriction training in healthy athletes. Methods. PRISMA guidelines were used to carry out the systematic review and meta-analysis. Three electronic databases were searched: MEDLINE, PEDro, and the Cochrane Library. Papers included in the study have the following characteristics: a) a randomized controlled trial or clinical trial design of research, b) studies investigating physiological effects of BFR training in healthy athletes and c) published in English. The approach to data extraction was chosen on the basis of the Cochrane Methods. Studies quality and risk of bias of the clinical trials included were evaluated according to a Jadad score and through meta-analysis. Results. After the elimination of duplicates, 164 records were screened. Among these, 14 studies were included in the systematic review. Seven of these were involved in the meta-analysis. From the qualitative analysis, a larger number of studies were found with a low level of quality. Conclusions. The application of BFR positively influences muscular adaptations compared with exercise under normal blood-flow conditions, in terms of increased VO 2 max, higher strength increase, and muscles adaptations. Thus, BFR provides a feasible, promising, and beneficial complementary training stimuli when used in a controlled environment supervised by trained and experienced personnel.

“…These elite triathletes, having completed years of specialized training, have relatively high and stable VO 2 max values. According to previous studies, an effective training method, such as high-intensity interval training, can increase VO 2 max [ 50 ], and blood flow restriction during low-intensity rowing can also significantly improve the VO 2 max in elite rowers [ 51 ]. Regarding nutritional strategy (e.g., ketogenic diet and vitamin D supplementation), the VO 2 max was not significantly elevated in endurance athletes and military recruits [ 52 , 53 ].…”

Lactobacillus plantarum PS128 Improves Physiological Adaptation and Performance in Triathletes through Gut Microbiota Modulation

et al. 2020

A triathlon is an extremely high-intensity exercise and a challenge for physiological adaptation. A triathlete’s microbiome might be modulated by diet, age, medical treatments, lifestyle, and exercise, thereby maintaining aerobiosis and optimum health and performance. Probiotics, prebiotics, and synbiotics have been reported to have health-promoting activities (e.g., immunoregulation and cancer prevention). However, few studies have addressed how probiotics affect the microbiota of athletes and how this translates into functional activities. In our previous study, we found that Lactobacillus plantarum PS128 could ameliorate inflammation and oxidative stress, with improved exercise performance. Thus, here we investigate how the microbiota of triathletes are altered by L. plantarum PS128 supplementation, not only for exercise performance but also for possible physiological adaptation. The triathletes were assigned to two groups: an L. plantarum 128 supplement group (LG, 3 × 1010 colony-forming units (CFU)/day) and a placebo group (PG). Both groups continued with their regular exercise training for the next 4 weeks. The endurance performance, body composition, biochemistries, blood cells, microbiota, and associated metabolites were further investigated. PS128 significantly increased the athletes’ endurance, by about 130% as compared to the PG group, but there was no significant difference in maximal oxygen consumption (VO2max) and composition between groups. The PS128 supplementation (LG) modulated the athlete’s microbiota with both significant decreases (Anaerotruncus, Caproiciproducens, Coprobacillus, Desulfovibrio, Dielma, Family_XIII, Holdemania, and Oxalobacter) and increases (Akkermansia, Bifidobacterium, Butyricimonas, and Lactobacillus), and the LG showed lower diversity when compared to the PG. Also, the short-chain fatty acids (SCFAs; acetate, propionate, and butyrate) of the LG were significantly higher than the PG, which might be a result of a modulation of the associated microbiota. In conclusion, PS128 supplementation was associated with an improvement on endurance running performance through microbiota modulation and related metabolites, but not in maximal oxygen uptake.

“…The use of BFR in conjunction with traditional high intensity training has also become more common among competitive athletes and may allow them to maintain or progress their training during the competition season [24,25]. The responses to training with BFR have even been explored in horse [26] and rat [27] models and indicate the potential for improvements in muscle size and strength may exist in species other than humans.…”
