“…Nevertheless, this type of exercise has shown exacerbated increases in sympathetic modulation and BP because of its higher exercise metaboreflex and pressor reflex stimulation [43,44,47]. LL, when performed until the muscular failure, is also effective for increasing muscle mass and strength, independent of BFR [2]. On the other hand, the high volume of LL would also in-…”

Increase in muscle mass and strength through resistance exercise (RE) has been highly recommended for healthy aging. On the other hand, RE could lead to acute cardiovascular risks prompted mainly by intense blood pressure elevations and cardiac autonomic imbalance. We compared the cardiovascular responses to three different RE protocols performed by 21 healthy elderly on a leg press machine. The protocols tested were high load (80% 1RM) until muscular failure (HL); low load (30% 1RM) until muscular failure (LL); low load, 30 repetitions followed by 3 sets of 15 repetitions, with 50% blood flow restriction (LL-BFR); and a control session (CON). Based on heart rate variability analysis, only LL kept parasympathetic indexes lower than CON at 30 min recovery. By finger photoplethysmography, LL-BFR prompted higher systolic and mainly diastolic blood pressure increments in many sets. The heart rate and cardiac output increase, and total peripheral resistance reduction following exercise were not different among RE protocols. There was no significant post-exercise hypotension and carotid arterial compliance changes. HL seems to be the safer protocol to be recommended for the healthy elderly, because it induces lower blood pressure increments and faster parasympathetic recovery compared to LL and LL-BFR.

“…In this way, some researches have postulated the determinacy of failure repetitions number achievement to induce muscle adaptations (12,22,24) . We showed elderly people need lower repetitions number to reach failure for LL, which means the exercise prescription for elderly men should not be based on the same RM range than young men.…”

Background: Aging process is characterized by reduction of muscle mass and strength, named sarcopenia. To attenuate these declines, resistance training has been purposed. The use 1RM test has been applied to define the maximal strength and prescription of exercise. Otherwise, it is not safe and it has not shown good practical applicability. Thus, the present study aim to compare the repetitions number for high and low load resistance exercise performed until failure between a young and elderly men groups. Methods: We compared (Mann-Whitney test) the repetitions number performed until muscle failure by 9 young and 9 elderly men at four sets 45ºleg press exercise for high (80% 1RM) and low load (30% 1RM). Results: Both groups reached maximum values for rate of perceived exertion, ensuring the muscle failure were achieved and no differences were seen between groups. The repetitions numbers were higher for young men with similar delta of reduction throughout sets between groups at low load resistance exercise. Otherwise, the delta of repetitions number reduction throughout sets at high load resistance exercise was higher for young men than elderly. Conclusions: We conclude elderly people need to perform lower number of repetition to reach muscle failure and thus achieve the desired training stimulus, mainly in low load resistance exercise. Furthermore, as they have better resistance to fatigue along sets the reduction of repetition number along sets is lower for them mainly when high load resistance exercise is performed.

“…In studies of adult populations where effort is controlled between different loading conditions by having participants train to momentary concentric failure LL conditions consistently produce higher volume-load performances compared with HLs (Barcelos et al, 2015;Mitchell et al, 2012;Schoenfeld et al, 2015;. In addition, where relative loadings are kept constant absolute volume-load typically increases over the course of a RT intervention due to participants' increases in strength (Ribeiro et al, 2015).…”

“…However, the absolute difference between the groups was very small and so it is likely that any difference is relatively meaningless. Further, most research to date suggests that when RT is performed to momentary failure adaptations such as strength and absolute endurance are likely to be similar (Barcelos et al, 2015;Mitchell et al, 2012;Schoenfeld et al, 2015;. Most research to date however has seemingly been conducted with adult populations, including the elderly.…”

“…Considering the potential value of increased muscular strength, studies examining the efficacy of RT protocols and indeed the variables important for optimizing such outcomes are of importance. (Micthell et al, 2012;Ogborn & Schoenfeld, 2014;Barcelos et al, 2015;Schoenfeld et al, 2015;. Volume-load changes across the duration of an intervention have indeed been reported as greater in LL RT .…”

Low-load resistance training promotes muscular adaptation regardless of vascular occlusion, load, or volume

Abstract: We conclude that 8 weeks of LLRT until failure in novice young lifters, regardless of occlusion, load or volume, produces similar magnitudes of muscular hypertrophy and strength.
