    Impacts of different triathlon races on systemic cytokine profile and metabolic parameters in healthy individuals: a systematic review
    (Bmc, 2023) de Sousa Fernandes, Matheus Santos; Gomes, Jefferson Mariano; Aidar, Felipe J.; Thuany, Mabliny; Filgueira, Tayrine Ordonio; de Souza, Raphael Fabricio; Badicu, Georgian
    The present systematic review aimed to discuss the impacts of different triathlon protocols on the level of pro and anti-inflammatory cytokines, as well as biomarkers related to the performance of healthy individuals. Four databases [PubMed (28 articles), Scopus (24 articles), Science Direct (200 articles), and SPORT Discus (1101 articles) were assessed. The eligibility criteria were applied, and the selected articles were used in the peer review, independently, as they were identified by March 2022. Of the 1359 articles found, 10 were included in this systematic review. Despite the difference in triathlon protocols, it was observed an increase in pro and anti-inflammatory cytokines including IL-4 and IL-10, and chemokines, such as IL-8 and MCP-1. Moreover, the anti-inflammatory serum levels increase after triathlon. Overall, the studies also reported enhancement in the serum levels of cortisol, creatine kinase, C reactive protein, Endothelial Growth Factor, Vascular Endothelial Growth Factor, Myostatin, Lactate dehydrogenase, free fatty acids, and lactate dehydrogenase in triathlon athletes. This systematic review indicates that different triathlon race promotes an acute elevation of circulating cytokines and chemokines levels which return to standard levels after triathlon races. The findings of this systematic review demonstrate that the modulation of inflammatory parameters may be associated with an increase in metabolic indicators (CK, Cortisol, and LDH) after the end of different types of triathlon races.

    Post-activation performance enhancement effect of drop jump on long jump performance during competition
    (Nature Portfolio, 2023) dos Santos Silva, Devisson; Boullosa, Daniel; Pereira, Erika Vitoria Moura; de Jesus Alves, Micael Deivison; de Sousa Fernandes, Matheus Santos; Badicu, Georgian; Yagin, Fatma Hilal
    Drop jump is widely used in training sessions, aiming for chronic effects on long jump performance. However, the acute effect of drop jump on long jump performance through its use as a Conditioning Activity (CA) has not been explored. The objective of this study was to verify the Post-activation Performance Enhancement (PAPE) responses induced by successive Drop Jumps (DJ) on competitive long jump performance. Eleven male jumpers (19.0 +/- 2.0 years; 178.0 +/- 9.0 cm; 73.1 +/- 8.9 kg; and personal record 5.78 +/- 0.44 m) volunteered for participation. The athletes performed 5 drop jumps 2 min (1 ' 45-2 ' 15 min) before the second, and fourth attempt during official competition of state level, the attempts without the use of CA were considered controls. The performance of the second (5.63 +/- 0.43 m), third (5.65 +/- 0.46, g = 0.24) and fourth (5.71 +/- 0.34 m) jumps performed after activation were higher than the first (5.54 +/- 0.45 m) in the control condition, p = 0.02, and p = 0.01 respectively. Differences were also found in the take-off vertical velocity of the jump between the fourth (1.55 +/- 0.21) and the first jump (1.30 +/- 0.40), p = 0.006. Jump performance showed positive correlation with approach velocity, r = 0.731, vertical take-off velocity, r = 0.412, and take-off duration, r = 0.508. The mean performance in jumping post-activation (5.67 +/- 0.38 m) was higher than that without the use of previous CA (5.59 +/- 0.44 m), p = 0.02, g = 0.19. The use of DJs as a CA prior to the long jump promotes improvements in the performance of the jump, which can be explained by the increase in the take-off vertical velocity in the athletes.
