Impact of Resistance Training Volume on Cognitive Function and Physical Performance in Cognitively Impaired Individuals

The participants will perform a control phase of six weeks of resistance training using the same volume for the upper (160 repetitions) and lower limbs (230 repetitions), with relative intensities ranging from 40% to 70% of 1RM. The training sequence will be the following: i) 10 minutes of warmup walking on the treadmill, ii) 1-3 sets of 5-10 repetitions at 50-70% of 1RM in the leg press, iii) 1-3 sets of 5-10 repetitions at 40-60% 1RM in the chest press, iv) 1-3 sets of 6-10 repetitions in the sit-to-stand exercise, v) 1-3 sets of 5-7 repetitions in the 1- kg medicine ball throw, and vi) 5 minutes walking on the treadmill.

The participants will perform ten weeks of resistance training, increasing their initial volume by 15% (upper limbs - 184 repetitions; lower limbs - 268 repetitions). The number of sets will range from 1 to 3, and the relative intensities from 40% to 70% 1RM. The training sequence will be the following: i) 10 minutes of warmup walking on the treadmill, ii) 1-3 sets of 3-10 repetitions at 50-70% of 1RM in the leg press, iii) 1-3 sets of 3-10 repetitions at 40-60% 1RM in the chest press, iv) 1-3 sets of 4-10 repetitions in the sit-to-stand exercise, v) 1-3 sets of 3-8 repetitions in the 1- kg medicine ball throw, and vi) 5 minutes walking on the treadmill.

The participants will perform ten weeks of resistance training, increasing their initial volume by 30% (upper limbs - 208 repetitions; lower limbs - 300 repetitions). The number of sets will range from 1 to 3, and the relative intensities from 40% to 70% 1RM. The training sequence will be the following: i) 10 minutes of warmup walking on the treadmill, ii) 1-3 sets of 4-10 repetitions at 50-70% of 1RM in the leg press, iii) 1-3 sets of 4-10 repetitions at 40-60% 1RM in the chest press, iv) 1-3 sets of 5-10 repetitions in the sit-to-stand exercise, v) 1-3 sets of 4-7 repetitions in the 1- kg medicine ball throw, and vi) 5 minutes walking on the treadmill.

The participants will perform 10 weeks of resistance training. The group that performed a 15% volume will now increase more by 15% and perform 30% (upper limbs - 208 repetitions; lower limbs - 300 repetitions). The number of sets will range from 1 to 3, and the relative intensities from 40% to 70% 1RM. The training sequence will be the following: i) 10 minutes of warmup walking on the treadmill, ii) 1-3 sets of 4-10 repetitions at 50-70% of 1RM in the leg press, iii) 1-3 sets of 4-10 repetitions at 40-60% 1RM in the chest press, iv) 1-3 sets of 5-10 repetitions in the sit-to-stand exercise, v) 1-3 sets of 4-7 repetitions in the 1- kg medicine ball throw, and vi) 5 minutes walking on the treadmill.

The participants will perform 10 weeks of resistance training. The group that performed a 30% volume will now increase more by 15% and perform 45% (upper limbs - 232 repetitions; lower limbs - 334 repetitions). The number of sets will range from 1 to 3, and the relative intensities from 40% to 70% 1RM. The training sequence will be the following: i) 10 minutes of warmup walking on the treadmill, ii) 1-3 sets of 3-10 repetitions at 50-70% of 1RM in the leg press, iii) 1-3 sets of 3-10 repetitions at 40-60% 1RM in the chest press, iv) 2-3 sets of 8 repetitions in the sit-to-stand exercise, v) 2-3 sets of 8 repetitions in the 1- kg medicine ball throw, and vi) 5 minutes walking on the treadmill.

The participants in the control group will maintain their regular daily activities without performing any form of physical exercise.
