“…Effects of the use of nutritional supplements in sports are widely studied. The results of numerous investigations referring to the biological action, duration of supplementation and recommended doses are currently published in the scientific literature ( Czeczelewski et al, 2013 ; Desbrow et al, 2012 ; Helms et al, 2014 ; Patlar et al, 2012 ; Ranchordas et al, 2013 ; Roshan et al, 2013 ; Santos et al, 2012 ; Seferoğlu et al, 2012 ), and this information is sometimes listed on the label; therefore, sport physicians, coaches and athletes usually know how to use those products. Yet, knowledge of the physiological action of exotic herbs among sport physicians seems to be inadequate in the light of the large number of easily available over-the-counter new herbal products accompanied by a limited number of clinical trials and up-to-date information.…”

Herbal and nutritional supplements are more and more popular in the western population. One of them is an extract of an exotic plant, named Tribulus terrestris (TT). TT is a component of several supplements that are available over-the-counter and widely recommended, generally as enhancers of human vitality. TT is touted as a testosterone booster and remedy for impaired erectile function; therefore, it is targeted at physically active men, including male athletes. Based on the scientific literature describing the results of clinical trials, this review attempted to verify information on marketing TT with particular reference to the needs of athletes. It was found that there are few reliable data on the usefulness of TT in competitive sport. In humans, a TT extract used alone without additional components does not improve androgenic status or physical performance among athletes. The results of a few studies have showed that the combination of TT with other pharmacological components increases testosterone levels, but it was not discovered which components of the mixture contributed to that effect. TT contains several organic compounds including alkaloids and steroidal glycosides, of which pharmacological action in humans is not completely explained. One anti-doping study reported an incident with a TT supplement contaminated by a banned steroid. Toxicological studies regarding TT have been carried out on animals only, however, one accidental poisoning of a man was described. The Australian Institute of Sport does not recommend athletes’ usage of TT. So far, the published data concerning TT do not provide strong evidence for either usefulness or safe usage in sport.

“…Numerous studies have sought to assess whether supplementation of omega 3 fatty acids can decrease the muscle damage degree, oxidative stress, and inflammation after exercise (Arab‐Tehrany et al., 2012 ; Davinelli et al., 2019 ; Tan & Norhaizan, 2019 ). However, more investigations have illustrated a significant effect of omega 3 LC‐PUFA in relation to improving EIMD, DOMS, oxidative stress, and inflammation following exercise (Gray et al., 2014 ; Jouris et al., 2011 ; Rajabi et al., 2013 ; Santos et al., 2012 ; Tartibian et al., 2011 ), and some studies have represented no effect (Lenn et al., 2002 ; López‐Seoane et al., 2021 ; Phillips et al., 2003 ). It is possible that the differences in exercise protocols, supplementation duration and dosage, participant's population, timing of supplementation and measurements and biomarkers selection relate to the discrepancies in the outcomes between investigations.…”

Damaged muscle cells start a reactions cascade that leads to a complicated and prolonged interaction between protein synthesis and degradation (Shen et al., 2018). Therewith, while protein turnover is increased, generally degradation exceeds synthesis, since the breakdown of protein results, leading to muscle atrophy, muscle degeneration, and exercise-induced muscle damage (EIMD; Damas et al., 2016). Exercise-induced muscle damage lead to alteration in muscle protein structure, reductions in muscle

“…Santos et al. (2012) reported that supplementation with DHA (360 mg/day) and EPA (540 mg/day) over the course of 4 weeks decreased C-reactive protein (CRP), and attenuated inflammatory activity induced by five consecutive days of intense military training (i.e., constant physical exertion and sleep/food deprivation). Based on the potential health benefits of n-3s for military personnel (Santos et al.…”

“…Indeed, n-3 status is lower in military personnel compared to the general U.S. population (Lewis et al 2011). Santos et al (2012) reported that supplementation with DHA (360 mg/day) and EPA (540 mg/day) over the course of 4 weeks decreased C-reactive protein (CRP), and attenuated inflammatory activity induced by five consecutive days of intense military training (i.e., constant physical exertion and sleep/ food deprivation).

Development of n-3 fortified, shelf-stable foods is facilitated by encapsulated docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), since natural n-3 food sources cannot withstand high temperature and prolonged shelf life. Organoleptic stability of n-3 fortified, shelf-stable foods has been demonstrated, but chemical changes in the food matrix throughout storage could conceivably impact digestibility of the protein-based encapsulant thereby compromising n-3 bioavailability. We assessed the effect of prolonged high-temperature storage and variations in food matrix (proteinaceous or carbohydrate) on the time course and magnitude of blood fatty acids changes associated with ingestion of n-3 fortified foods. Low-protein (i.e., cake) and high-protein (i.e., meat sticks) items were supplemented with 600 mg encapsulated DHA+EPA, and frozen either immediately after production (FRESH) or after 6 months storage at 100°F (STORED). Fourteen volunteers consumed one item per week (randomized) for 4 weeks. Blood samples obtained at baseline, 2, 4, and 6 h post-consumption were analyzed for circulating long-chain omega 3 fatty acids (LCn3). There was no difference in LCn3 area under the curve between items. LCn3 in response to cakes peaked at 2-h (FRESH: 54.0 ± 16.8 μg/mL, +18%; STORED: 53.0 ± 13.2 μg/mL, +20%), while meats peaked at 4-h (FRESH: 51.9 ± 12.5 μg/mL, +22%; STORED: 53.2 ± 16.9 μg/mL, +18%). There were no appreciable differences in time course or magnitude of n-3 appearance in response to storage conditions for either food types. Thus, bioavailability of encapsulated DHA/EPA, within low- and high-protein food items, was not affected by high-temperature shelf-storage. A shelf-stable, low- or high-protein food item with encapsulated DHA/EPA is suitable for use in shelf-stable foods.
