Escalas de percepção subjetiva de esforço têm sido usadas há bastante tempo para se referir à intensidade de esforço no exercício aeróbio. Somente há pouco tempo foi validada a escala de OMNI-RES para exercício resistido, de modo que sua aplicação em algumas populações ainda é escassa. Assim, o objetivo deste estudo foi avaliar a efetividade da escala de OMNI-RES em mulheres idosas hipertensas. Vinte e uma voluntárias (60.2±3,8 anos, IMC de 28,7±1,2 Kg/m2), realizaram quatro sessões de exercício resistido randomicamente ordenadas. Duas das sessões eram para membros inferiores (MI), com intensidades de 60% e 80% de 15 RM, e as outras duas, para membros superiores (MS), com as mesmas intensidades. As sessões tiveram três séries de 15 repetições e intervalos de 90 segundos. Ao final de cada série, mediu-se a frequência cardíaca e a percepção subjetiva foi referida pelas mulheres. Para a análise estatística, foi utilizado o teste de ANOVA two-way. A frequência cardíaca se apresentou significativamente mais elevada nas sessões a 80% de 15RM em relação a 60% de 15RM em todas as séries, tanto de membros superiores quanto de membros inferiores. Nos protocolos para MI, as mulheres referiram pontuações na escala de OMNI-RES sempre significativamente maiores ao final das três séries, com intensidade de 80% em relação a 60% de 15 RM (6,1±0,1 versus 3,7±0,1; 6,1±0,1 versus 3,8±0,2 e 6,1±0,1 versus 3,9±0,2 para as 1ª, 2ª e 3ª séries a 80 e 60% respectivamente). Nos protocolos para MS a pontuação na escala de OMNI-RES foi igualmente maior para os exercícios a 80% de 1RM em todas as séries (6,1±0,1 versus 3,5±0,1; 6,1±0,1 versus 3,5±0,1 e 6,1±0,1 versus 3,6±0,1 para as 1ª, 2ª e 3ª séries a 80 e 60% respectiva  mente). Os valores de pontuação foram equivalentes à classificação de razoavelmente leve e compatível com treino de endurance muscular segundo a escala de OMNI-RES nos exercícios a 60% de 15 RM e razoavelmente pesado e compatível com treinamento de hipertrofia para a intensidade de 80% de 15RM. Concluiu-se que a escala de OMNI-RES representa adequadamente a intensidade adotada em exercícios resistidos com características de Resistência Muscular Localizada (RML) e hipertrofia em mulheres idosas hipertensas. THE USE OF THE OMNI-RES SCALE IN HYPERTENSIVE ELDERLY abstract Scales of perceived exertion have been used for some time to refer to the intensity of effort in an aerobic exercise. Only recently the OMNI-RES scale has been validated for resistance exercise, as a result of that its application in some populations is still scarce. Thus, the purpose of this study was to evaluate the effectiveness of the OMNI-RES scale in elderly women with hypertension. Twenty one volunteers (60,2 ± 3,8 years, BMI 28,7 ± 1,2 Kg/m2), undertook four sessions of resistance exercise ordered randomly. Two of those sessions were for lower limbs at intensities of 60% and 80% of 15RM, and the other two were for upper limbs with the same intensity. The sessions had 3 sets of 15 repetitions and intervals of 90 seconds. At the end of each series it was measured the heart rate and the subjective perception was reported by the women. For statistical analysis, it was used the two-way ANOVA test. Heart rate was significantly higher in sessions at 80% with 15RM than at 60% with 15RM in all series, both upper limbs and lower limbs. In the protocols for lower limbs, the women always reported significantly higher scores on the OMNI-RES at the end of the three series with an intensity of 80% compared to 60% with 15 RM (6,1 ± 0,1  versus 3,7 ± 0,1; 6,1 ± 0,1 versus 3,8 ± 0,2 and 6,1 ± 0,1 versus 3,9 ± 0,2 for the 1st, 2nd and 3rd grades 80 and 60% respectively). The values in scores were equivalent to the classification of fairly mild consistent with muscle endurance training according to the OMNI-RES scale on the exercises at 60% with 15 RM and fairly heavy and consistent with hypertrophy training at an intensity of 80% with 15RM. It was concluded that the OMNI-RES scale adequately represented the adopted intensity in resistance exercises with features of RML and hypertrophy in hypertensive elderly women.

Objective To assess the trainability and reversibility of variables of physical fitness in elderly participants in Active Living Functional Gymnastics. Method This ex post facto study was composed of 115 elderly women from six functional fitness groups in the Active Living Program in Florianopolis. The Rikli and Jones battery of tests (Chair Stand Test, Arm Curl Test, Chair Sit and Reach Test, Back Scratch Test, 8-Foot Up and Go Test, 6 Minute Walk Test) was used. The intervention period lasted for eight months, and the detraining period took three months. Descriptive and inferential statistics with paired Student t-test and Scheffé post hoc was used. Results The performance of the age groups differed in agility and aerobic capacity; Trainability was identified in the strength and resistance variables of the lower and upper limbs, and the flexibility of the lower limbs; Detraining was perceived in the strength and resistance of upper limbs, and aerobic capacity. Conclusion A Functional Gymnastics program produces positive effects on the strength and resistance of the lower and upper limbs, and flexibility of the lower limbs in elderly women. An interruption period lasting three months results in detraining in strength and resistance of the lower limbs and aerobic capacity.

This study compared undifferentiated ratings of perceived exertion (RPE) during short duration, very high intensity cycle exercise using high and low resistance. 30 recreationally trained males (24.2 ± 2.4 yr.) were memory-anchored to the Borg 15-category scale. The high and low resistance exercises were defined by 30-sec. maximum tests assigned in counterbalanced order, with resistances set before testing during an orientation session. High resistance was 10% of body mass. Low resistance resulted in the same total work as the high resistance over the 30-sec. sessions (± 5%) but increased pedal rate. RPE was taken at 8, 13, 18, 23, and 28 sec. during the high and the low resistance exercises. Measurements were compared using a 2-way repeated-measures analysis of variance. RPE was significantly greater ( p = .005) for the high than the low resistance exercise at each interval. RPE increased when the subjects were required to pedal against a greater resistance and produce the highest forces. These RPE data are consistent with data from both aerobic cycle and resistance exercise. The data suggest that instantaneous force production, not summed work, is a primary determinant of RPE. All of these observations support Cafarelli's theoretical model of effort sense. In conclusion, as an individual generates more force during high resistance exercise than in light resistance exercise, a potential explanation of our results is that the increased motor outflow and corollary sensory signal lead to a greater sense of effort.

AbstractPrior research about the effects of the amount of exercised muscle mass upon cardiovascular responses (CVR) has neglected a potential bias related to total exercise and concentric/eccentric duration. Autonomic responses and perceived exertion (RPE) were compared in resistance exercises performed with larger and smaller muscle mass and matched for total exercise and concentric/eccentric duration. Twelve men performed 4 sets of 12 repetitions of unilateral (UNI) and bilateral (BIL) knee extensions at 70% of 12RM. Increases in CVR were always greater at the last set of BIL over UNI, as were SBP (35% vs. 23%), DBP (36% vs. 23%), HR (40% vs. 26%), RRP (90% vs 53%) and CO (55% vs 39%). No difference between protocols was found for autonomic modulation before and after exercise, but BIL induced significantly greater changes than UNI from baseline for R-R intervals (−13% vs. −7%), SDNN (−38% vs. −17%) and rMSSD (−41% vs. −21%). The rate of perceived exertion in the last set was higher in BIL than UNI (7.6±0.5 vs. 6.6±1.4 OMNI-RES; P<0.05) and did not correlate with any CVR. Thus, CVR were greater in resistance exercise performed with larger than smaller muscle mass. This information is relevant for patients with high cardiovascular risk.

Repetitions To Failure

Carbohydrate mouth rinsing has been shown to enhance aerobic exercise performance, but there is limited research with resistance exercise (RE). Therefore, the purpose of this investigation was to examine the effects of carbohydrate mouth rinsing during a high-volume upper body RE protocol on performance, heart rate responses, ratings of perceived exertion, and felt arousal. Recreationally experienced resistance-trained males (N = 17, age: 21 ± 1 years, height: 177.3 ± 5.2 cm, mass: 83.5 ± 9.3 kg) completed three experimental sessions, with the first serving as familiarization to the RE protocol. During the final two trials, the participants rinsed a 25-ml solution containing either a 6% carbohydrate solution or an artificially flavored placebo in a randomized, counterbalanced, and double-blinded fashion. The participants rinsed a total of nine times immediately before beginning the protocol and 20 s before repetitions to failure with the exercises bench press, bent-over row, incline bench press, close-grip row, hammer curls, skull crushers (all completed at 70% one-repetition maximum), push-ups, and pull-ups. Heart rate, ratings of perceived exertion, and felt arousal were measured at the baseline and immediately after each set of repetitions to failure. There were no differences for the total repetitions completed (carbohydrate = 203 ± 25 repetitions vs. placebo = 201 ± 23 repetitions, p = .46, Cohen’s d = 0.10). No treatment differences were observed for heart rate, ratings of perceived exertion, or felt arousal (p > .05). Although carbohydrate mouth rinsing has been shown to be effective in increasing aerobic performance, the results from this investigation show no benefit in RE performance in resistance-trained males.

Introduction: The anaerobic threshold (AT) determination is important for individualizing the aerobic training prescription. Objective: To compare and verify the agreement between oxygen uptake (VO2), heart rate (HR), and rate of perceived exertion (RPE) at the AT determined by the ventilatory threshold (VT) and heart rate deflection point (HRDP) methods during an aquatic incremental test in trained older women. Methods: Nine elderly women (64.3 ± 4.4 years) engaged in a water-based training program in the last three months performed a maximum incremental test using the water-based stationary running exercise. The test started at a 70 bpm cadence for 2 min, followed by 15 bpm increments every 2 min until exhaustion. VO2, HR and RPE were measured throughout the test and the AT was identified for each method (i.e., VT and HRDP) by three experienced physiologists. Paired t-test and Bland-Altman analysis were used for data analysis (α=0.05). Results: There was no difference between the VT and HRDP methods (p>0.05) and the Bland-Altman analysis showed acceptable agreement between them for all investigated outcomes (VO2: 22.9 ± 5.1 vs. 23.5 ± 4.7 ml.kg-1.min-1, IC95%: -3-+4 ml.kg-1.min-1; HR: 147 ± 11 vs. 147 ± 11 bpm, IC95%: -9-+8 bpm; RPE: 16 ± 1 vs. 16 ± 1, IC95%: -2-+3). Conclusion: Based on these findings, both HR and RPE determined by the HRDP can be used as valid parameters and practical tools for field prescription of intensity during water-based exercises in elderly trained women.Keywords: exercise, aging, exercise test, hydrotherapy, oxygen consumption.
