Associação entre dois diferentes tipos de estrangulamento com a variação da pressão intraocular em atletas de jiu-jitsu

PURPOSE To verify the association between two different types of strangling with intraocular pressure variation in jiu-jitsu athletes. METHODS An observational study was performed on 9 athletes of jiu-jitsu, with at least 6 month of training, male, aged 20 to 30 years, without any physical and eyeball lesions. Associations between intraocular pressure and Cross Choke from the guard strangling (E1), and E2 - Cross Choke from mount strangling were gotten. Intraocular pressure was determined by using Perkins tonometer, at first in the absence of physical exercise over the last 24 hours and after each strangling. Then it was carried out the intraocular pressure measure at each 3 minutes, during 12 minutes of exercise recovery (R1, R2, R3, and R4) keeping the athletes lied down. Statistical analysis was done using ANOVA test and Bonferroni post-test. RESULTS Meaningful reduction of both eyes intraocular pressure occurred at the E2 situation comparing to the E1 situation at all exercise recovery measures: R1 (OD: 8.22 +/- 1.39 vs.11.33 +/- 2.00 / OE: 8.55 +/- 1.23 vs. 11.88 +/- 1.90), R2 (OD: 8.44 +/- 1.87 vs.10.22 +/- 2.53 / OE: 9.00 +/- 1.80 vs. 10.44 +/- 2.35), R3 (OD: 8.44 +/- 1.74 vs.9.78 +/- 2.54 / OE: 8.55 +/- 1.42 vs. 10.33 +/- 1.93) all with p<0,01 e R4 (OD: 8.88 +/- 2.08 vs.9.55 +/- 2.87 / OE: 9.11 +/- 1.53 vs. 10.44 +/- 2.18) with p<0.05. Meaningful IOP reduction (p<0.05) was observed at the R1 moment of E2 strangling (OD: 10.77 +/- 1.92 vs.8.22 +/- 1.39 / OE: 11.44 +/- 1.94 vs. 8.55 +/- 1.23). CONCLUSION There is association between intraocular pressure and jiu-jitsu strangling exercises, with intraocular pressure reduction.

Variação da pressão intraocular após teste submáximo de força no treinamento resistido

ABSTRACT Purpose: To verify the intraocular pressure (IOP) after sub-maximal strength test. Methods: 145 Physical Educationfreshmen (22.04 ± 4.17 years old; female and male) from Supe-rior Physical Education School of Jundiai (ESEFJ) were eva-luated in an observacional study. The exclusion criteria were:media opacity and eyeball absence or changes. All subjectsagreed to take part in this research and signed up the InformedConsent. IOP was measured by Perkins tonometer: i) pretest:just before the submaximal strength test performance and ii)post-test: immediately after the strength test. The strength testconsisted in the one-repetition-maximum-assessment throughrepetition until fatigue. Resistance training exercises such asbench press, pulley dorsal high, shoulder press, arm curl andleg press 45o were performed. Statistical analyses were obtai-ned through paired Student’s “t” test. Results: Decrease ofIOP was observed after the strength test: 13.48 ± 3.32 vs.10.20 ±3.72 (p<0.001) in the right eye and 13.13 ± 3.96 vs.9.74 ± 3.33(p<0.001) in the left eye.

Variação da pressão intraocular no exercício resistido realizado em duas diferentes posições

Objective To verify the variation in IOP in the resistance exercise performed in the sitting and supine. Methods A 14 volunteers of the Center for Physical Activities of the Sorocaba Eye Bank (BOS Fit). Exclusion criteria were adopted: I) media opacity; II) change in volume of the eyeball or no eyeball; III) IOP greater than 21mmHg; IV) age 20 and over 40; V) time practice of resistance training less than 30 days. Initially the test was performed to predict the leg press exercise to determine the percentage charge for the exercise thereof during the experiment. The volunteers underwent two interventions separated by an interval of 72 hours, both with the same volume and intensity in the leg press exercise, 3 sets of 15 repetitions with 60% 1RM, interval time between sets 60 seconds and moderate speed, according to the following positions: P1) leg press performed in the sitting position and P2) leg press in supine position. IOP was obtained using the Perkins tonometer in three moments: M1) immediately before exercise; M2) immediately after the third series; M3) three minutes after completion of third grade. Each sequence was obtained by measuring the position of their exercise performance. Results We found that in both positions there was a significant drop in IOP after exercise (M2), remained significantly reduced after three minutes of recovery (M3). However, there was no difference in IOP second position (P1 and P2), regardless of time of measurement (M1, M2 and M3). Conclusion There was a decrease in IOP due to resistance exercise and was not observes differential response of IOP of IOP according to the position of the exercise.

Comparação de resposta da pressão intraocular frente a duas diferentes intensidades e volumes do treinamento resistido

Abstract Purpose: To verify the influence of two different intensities and volumes of resistance training on intraocular pressur. Method: Nineteen athletes boxers (13 male and 6 female; mean age of 22 ± 3 years) were randomly assigned to two different resistance exercise sessions: muscular endurance with 3 sets of 15 repetition maximum and muscular hypertrophy with 4 sets of 8 RM. The intraocular pressure was measured with a Perkins tonometer before, during and after the resistance exercise sessions. Data were expressed as mean and standard deviation. A repeated-measures analysis of variance (ANOVA) was used and the Tukey post hoc test for multiple comparisons were applied. Results: A reduction in intraocular pressure during the resistance exercise session was observed. However, the muscular endurance exercise produced a significant reduction in intraocular pressure when compared with muscular hypertrophy. At the end of session, intraocular pressure returned to pre-exercise levels in muscular endurance session and above to pre-exercise levels in hypertrophy session. Conclusion: Resistance exercises influence intraocular pressure values, thus 3 sets of 15 repetitions with 60%1RM promote better intraocular pressure responses than 3 sets of 8 repetitions with 80% 1RM. This finding of the present research can contribute in prescription of resistance exercise to people with glaucoma risk factors.
