The LI-BFR session exhibited similar blood lactate to the HI, a higher rating of perceived response than the HI and LI, and equal or lower hemodynamic responses than the HI.

A single bout of resistance exercise can have a BP-lowering effect that last for up to 24 hours. Supine recovery and the use of larger muscle groups resulted in greater BP reductions after resistance exercise.

This study examined the performance effects of exercise order during a resistance-training session composed of only upper-body exercises. The 10 repetition maximum of 14 men and 4 women with at least 6 months of previous weight-training experience was determined for 5 upper-body exercises. Each subject then completed 2 training sessions separated by 48 hours in a counterbalanced crossover design. One session began with exercises of the large-muscle group and progressed to exercises of the small-muscle group (sequence A), whereas the other session was performed with the opposite exercise sequence (sequence B). The exercise order for sequence A was free-weight bench press (BP), machine lat pull-down (LPD), seated machine shoulder press (SP), standing free-weight biceps curl (BC) with a straight bar, and seated machine triceps extension (TE). The exercise order for sequence B was TE, BC, SP, LPD, and BP. During both sequences, 3 sets of each exercise were performed to concentric failure, with 2-minute recovery intervals between sets and exercises. Performing exercises of both the large- and the small-muscle groups at the end of an exercise sequence resulted in significantly fewer repetitions in the 3 sets of an exercise. This decrease in the number of repetitions performed was especially apparent in the third set when an exercise was performed last in an exercise sequence.

The effects of muscle mass and number of sets on postexercise hypotension (PEH) following resistance exercises are barely known. The aim of the study was to compare systolic blood pressure (SBP), diastolic blood pressure, and mean arterial blood pressure (MAP) after biceps curl and leg extension with different number of sets. Twenty-four trained men (23 +/- 1 year, 69 +/- 4 kg, 173 +/- 3 cm) were randomly assigned into control group, arm group, and leg group. On the first day, the 12 repetition maximum (12RM) workload was determined for both experimental groups. In the remaining days, arm group and leg group performed, randomly, 6 or 10 sets of 10 repetitions of the respective exercises at 12RM workload. Blood pressure was assessed before and every 10 minutes after the exercises for 1 hour. The 3-way analysis of variance identified a significant influence of the type of exercise (p = 0.000001), number of sets (p = 0.007), and postexercise period (p = 0.009) on SBP and of the type of exercise (p = 0.03) on MAP. No differences were found among the groups at rest. Postexercise hypotension was only observed for the leg group when 10 sets were performed. In this group, SBP was significantly (p

4 mg.kg did not alter HR but improved performance on SJFT in young judo athletes and reduced the RPE.
