Resumen
- English
This study aimed to verify the intraocular pressure variation (IOP) on the exercise of bench press realized in positions such as straight, inclined and declined. Eight healthy individuals were evaluated during three sessions of resistance exercise on bench press with volume and intensity of 3 sets of 15 repetitions with 60% 1 RM. The interval time between sets was 60 seconds and moderate speed, according to the following positions: P1) bench press performed in straight position (0°); P2) bench press performed in inclined position (45°); P3) bench press performed in the declined position (-30°). The intraocular pressure was determined by using a Perkins’ tonometer in three distinct moments, as follows: M1) immediately before the exercise; M2) immediately after of the third repetition; M3) three minutes after the end of the third repetition. Statistical analysis was performed using the Shapiro-Wilk normality test and it ANOVA was also used with Bonferroni post-test adopting a significance level of 5%. The software used was GraphPad Prism®. The results showed the hypotensive effect of exercise in IOP, it was noticeable a significant reduction in IOP after exercising in the bench press independently of the chosen body position and also an average reduction after the completion of the exercise - approximately 3-4 mmHg or 25%. It was concluded that even in potentially hypertensive position, the exercise caused a significant reduction of the IOP. One can attribute the drop in IOP due to the resistance exercise, the mechanisms related to the reduced production of aqueous humor in contrast to the increase flow of this liquid by camerular sinus.

O objetivo do estudo foi verificar a variação da pressão intraocular (PIO) no exercício de supino realizado nas posições reto, inclinado e declinado. Foram avaliados oito indivíduos saudáveis, submetidos a três sessões do exercício resistido de supino, com volume e intensidade de 3 séries de 15 repetições com 60% 1RM, intervalo de 60 segundos entre as séries e velocidade moderada, de acordo com as seguintes posições: P1) Supino executado na posição reta (0º); P2) Supino executado na posição inclinada (45º) e P3) Supino executado na posição declinada (-30º). As mensurações da PIO foram realizadas utilizando o Tonômetro de Perkins em três momentos distintos, sendo: M1) imediatamente antes do exercício; M2) imediatamente após a terceira série e M3) três minutos após a finalização da terceira série. A análise estatística foi realizada pelo Teste de normalidade de Shapiro-Wilk, e utilizado ANOVA com pós-teste de Bonferroni adotando-se um nível de significância 5%. O software utilizado foi o GraphPad Prism®. Os resultados demonstraram o efeito hipotensor do exercício físico na PIO, foi observada uma redução significativa da PIO após o exercício no supino independentemente da posição corporal adotada, tendo apresentando uma redução média após a realização do exercício de aproximadamente 3 a 4 mmHg ou 25%. Concluímos então que mesmo em posição potencialmente hipertensiva, o exercício promoveu redução significativa da PIO. Pode-se atribuir a queda da PIO decorrente do exercício resistido, a mecanismos relacionados a diminuição da produção do humor aquoso em contrapartida ao aumento do escoamento desse líquido pelo ângulo camerular.
