“…There is evidence to suggest that distinct spatial and intensity discrimination circuits comprise a distributed network that is involved in somatic sensation (Olausson et al, 2005;Oshiro et al, 2009 comprises a key element in the dose-discrimination circuitry (Olausson et al, 2005;Oshiro et al, 2009), which is consistent with the observed robust capsaicin dose-dependent activations in this region. However, the anterior insula may also play a role in contributing the significance of a stimulus into decisions about pain (Wiech et al, 2010).…”

“…Algumas hipóteses são propostas para explicar o aumento do limiar da dor em atletas ou em pessoas ativas comparados com os sedentários. Como mencionado acima, a hipótese neurofisiológica mais explorada e aceita em seres humanos é, sem dúvida, a analgesia induzida pela liberação de opioides (62) . Segundo Koltyn (28) , o estímulo constante das fibras descendentes neuromotoras favoreceria a liberação de opioides endógenos.…”

“…Embora, a ação dos opioides seja a mais aceita, sendo frequentemente observado o aumento da atividade opioide endógena com o exercício (66,67) em nível sanguíneo (63,68) como no liquor cefalorraquidiano (67) , com aumento de betaendorfinas no tálamo, hipotálamo ventral e substância cinza periaquiducal) (28) . Alguns estudos (62,69) observam que o fenômeno não depende (apenas) da ação dos opioides, pois há alteração nos limiares de dor de atletas mesmo com a administração de naloxona intravenosa (antagonista opioide). A duração média dessa analgesia induzida pela atividade aeróbica é de 15 a 30 minutos (69,70) , podendo variar conforme as características de intensidade, duração e tipo de exercício.…”

“…Functional magnetic resonance imaging (fMRI) is widely used to investigate brain function during different motor tasks and various sensory stimulations in humans (Fransson et al, 1998(Fransson et al, , 1999Hofbauer et al, 2004Hofbauer et al, , 2006Hwang et al, 2005;Olausson et al, 2005;Seung et al, 2005;Elfgren et al, 2006;Pastor et al, 2006). The most commonly used technique relies on blood oxygenation level-dependent (BOLD) contrast, which is indirectly related to neuronal activity (Ogawa et al, 1993;Heeger and Ress, 2002;Thompson et al, 2003;Mukamel et al, 2005;Niessing et al, 2005).…”
