In this article, a comparison of concentracoes plasmaticas of cortisol, GH and insulina for leg press (LP) and supino reto (SR) exercises was conducted.
Abstract
INTRODUCAO: Muitos trabalhos tem estudado o comportamento hormonal nos exercicio resistido, entretanto poucos relacionam os hormonios cortisol, GH e insulina. OBJETIVO: Estudar os ajustes das concentracoes plasmaticas dos hormonios cortisol, GH e insulina em exercicios resistidos de mesma intensidade com relacao a massas musculares distintas. METODOS: Dez voluntarios, com 20,3 ± 4,2 anos, 74,1 ± 10,2 kg de peso, 177,2 ± 4,6 cm de estatura e 23,8 ± 3,2 kg/m2 de IMC, realizaram uma sessao de leg press (LP) e supino reto (SR) com quatro series com 10 repeticoes a 70% 1 RM com tres minutos de intervalo. Foram coletadas amostras de sangue para dosagem das concentracoes plasmaticas de cortisol, GH e insulina em repouso (Pre) e em 0' (Rec. 0'), 30' (Rec. 30') e 90' (Rec. 90') de recuperacao. RESULTADOS: As concentracoes plasmaticas de cortisol foram significativamente reduzidas ao final da recuperacao em LP (2,20±0,37 ng/dl para 1,33±0,38ng/dl) em relacao a pre-dosagem. As concentracoes de GH e insulina elevaram-se significativamente durante a recuperacao. GH em LP foi significativamente maior em Rec. 0' (2,75±3,29 ng/ml para 9,60±5,32 ng/dl) do que em pre. A insulina elevou-se significativamente em Rec. 30' em LP (14,70±7,92 ulU/ml para 21,66 ± 8,61 ulU/ml) e em SR (6,17 ± 2,99 ulU/ml para 19,70 ± 13,8 ulU/ml) em relacao a pre. As concentracoes plasmaticas de insulina pre em LP foram significativamente superiores a SR (14,70 ulU/ml e 6,17 ± 2,99 ulU/ml). CONCLUSAO: O exercicio resistido promoveu diferentes ajustes nas concentracoes hormonais de cortisol, GH e insulina durante o periodo de recuperacao.

Behavior of cortisol, ck and lactate in a session of variable resistance

TL;DR: Variables for muscular injury showed no evidence of alterations 24 hours after the CT sessions, hence confirming that the workload did not generate significant post-stress muscular injury.

Alterações eletrolíticas relacionadas à dor muscular após exercícios resistidos

TL;DR: In this paper, a high-intensity resistance exercise (RE) performed at high intensity cause an inflammatory response and electrolyte abnormalities in blood plasma, which are associated with delayed onset muscle soreness (DOMS).

Insulin receptor signals regulating GLUT4 translocation and actin dynamics.

TL;DR: Both spatial and temporal regulations of actin dynamics, both beneath the plasma membrane and around endomembranes, by insulin receptor signals are also involved in the process of GLUT4 translocation.

Associations of exercise-induced hormone profiles and gains in strength and hypertrophy in a large cohort after weight training

TL;DR: It is reported that the acute exercise-induced systemic hormonal responses of cortisol and GH are weakly correlated with resistance training-induced changes in fibre CSA and LBM (cortisol only), but not with changes in strength.

Growth hormone-induced alterations in the insulin-signaling system.

TL;DR: Interestingly, the modulation of Insulin signaling and action observed in states of GH excess, deficiency, or resistance seems to be relevant to the changes in longevity associated with those States.

Effects of rest duration between sets of resistance training on acute hormonal responses in trained women

TL;DR: The magnitude of acute GH responses in previously strength-trained women appears greater with a 30-s rest interval between sets compared to longer rest periods of 60- or 120-s.

Effects of very short rest periods on hormonal responses to resistance exercise in men.

TL;DR: The results of the present study support rest period in RE sets as an important variable to increase the anabolic hormone concentrations, and it should be mentioned that short rest intervals elevated greater increase in GH concentration compared with 120-second rest.
