Objective:

The aim of the study was to determine values of the 1RM test in multi and single‐joint exercises with and without visual deprivation.

Method:

Twelve trained men (23.00 ± 4.80 years; 80.76 ± 8.09kg; 1.76 ± 0.05cm) performed four visits (two for each exercise) consisting in 1RM tests for multi‐joint exercise (guided bar squat) and single‐joint exercise (biceps curl), with or without visual deprivation.

Results:

The T test found no significant differences between the visual deprivation methods for multi‐joint exercise both in absolute strength (Δ% = ‐ 6.13%; p = 0.422) as for relative strength (p = 0.397). The same occurred for the single‐joint exercise for absolute strength (Δ% = 1.43%; p = 0.220) and for relative strength (p = 0.230). Additionally, a small effect size was observed between 1RM tests in multi and single‐joint exercises in both visual protocols.

Conclusion:

According to the study results, we can conclude that for multi and single‐joint exercises protocol visual deprivation do not cause significant differences in the displacement of loads in 1RM test execution.
