Circulating microRNAs (c-miRNAs) in human plasma have been described as a potential marker of exercise. The present study investigated the effects of three acute resistance training (RT) protocols on the time-course changes of the c-miRNAs profiles in young males. The subjects (n = 45) were randomly divided into three groups: muscular strength endurance (SE), muscular hypertrophy (MH) and maximum strength (MS). Venous blood samples were obtained before exercise and immediately, 1 h and 24 h after each RT protocol to assess the following biological parameters: c-miRNAs, anabolic and catabolic hormones, inflammatory cytokines and muscle damage markers. The results revealed that the levels of two c-miRNAs (miR-208b and miR-532), six c-miRNAs (miR-133a, miR-133b, miR-206, miR-181a, miR-21 and miR-221) and two c-miRNAs (miR-133a and miR-133b) changed significantly in response to the SE, MH and MS protocols (p < 0.05), respectively. The nature and dynamic processes of the c-miRNAs response were likely influenced by the RT modality and intensity. Moreover, miR-532 was negatively correlated with insulin-like growth factor-1 and positively correlated with interleukin-10, whereas miR-133a was negatively correlated with cortisol and positively correlated with testosterone/cortisol. These findings suggest that these c-miRNAs may serve as markers for monitoring the RT responses.

“…(30). A rating of 0 was associated with no effort (seating or resting), and a rating of 1 corresponded to the perception of effort while performing an extremely easy effort (26). A rating of 10 was considered to be maximal effort and associated with the most stressful exercise ever performed (23).…”

Control of resistance training by perceived exertion and the EMG signal 2 2 ABSTRACTThe effectiveness of the OMNI-RES (0-10) and the electromyographic signal for monitoring changes in the movement velocity was examined during a set to muscular failure using different percentages of one repetition maximum (1RM) in the parallel squat exercise (PSQ). Twelve males (26.3 ± 5.8 years) were evaluated on eight separate days with 48 hours of rest between sessions. After determining the 1RM value, participants underwent seven tests until achieving muscular failure with the following percentage ranges: 30 to <40%; 40 to <50%, 50 to <60%, 60% to <70%, 70 to <80%, 80 to <90% and >90%. An optical rotary encoder measured mean accelerative velocity (MAV) and the OMNI-RES (0-10) scale was used to express the Rating of Perceived Exertion (RPE) after every repetition of each set. Additionally, the normalized root mean square (RMS) signal of the surface electromyography (N-EMG) was calculated for the vastus medialis muscle. The RPE expressed after the first repetition and when the maximum value of MAV was achieved along the sets was lower (p <0.001, d >0.8) than the RPE that corresponded to a 10% drop in MAV and at failure. Additionally, the initial RPE was useful to distinguish different loading zones by anchoring the OMNI-RES value to the magnitude of the relative load (<60%, 60 to <70% or ≤ 70% 1RM). Similar patterns were observed using the N-EMG. In conclusion, apart from differentiating between relative loads during a set to failure in the PSQ, the RPE and the N-EMG can both reflect changes associated with the initial, maximal, 10% drop in movement velocity and the muscular failure.

“…Numerous studies have revealed that participants report increasingly higher RPE values with increasing load/torque demands [3][4][5][6][7][8] even when matched for volume-load (repetitions x load) [9][10][11] . In addition a number of studies have reported a relationship between load, RPE and physiological measures such as: electromyography amplitude 3,6,8,12 , heart rate 5 , and blood lactate 12,13 .…”

Objectives: Rating of perceived exertion scales are commonly used in resistance training (RT) though most suffer from conflation of perceptions of both effort and discomfort by participants. The aim of this study was to examine reliability of trainee ratings of perceived effort (RPE-E) and discomfort (RPE-D) using two novel scales in addition to reliability and validity of trainer RPE-E.Design: Participants underwent 3 RT trials over a period of three weeks. Methods: Seventeen participants (males n = 6, females n = 11, age 63 ± 16 years) completed 5 RT exercises for a single set using a load permitting a self-determined 6 repetition maximum (meaning they determined inability to complete further repetitions if attempted i.e. they predicted momentary failure on the next repetition). Trainers completed their rating of RPE-E, followed by participants reporting of RPE-E and RPE-D immediately after completion of the exercises. Spearman's correlations examined the relationship between RPE-E and RPE-D. Reliability was examined as standard error of measurement (SEM) calculated for each outcome across the 3 trials (intra-rater), in addition to agreement between trainers (inter-rater), and agreement between trainer and trainee RPE-E. Results:Correlations between RPE-E and RPE-D were significant but weak (r = .373 to 0.492; p < 0.01). Intra-rater SEMs for trainee RPE-E ranged from 0.64 to 0.85, trainee RPE-D ranged from 0.60 to 1.00, and trainer RPE-E ranged from 0.56 to 0.71. Inter-rater SEMs for trainer RPE-E ranged 0.25 to 0.66. SEMs for agreement between trainer and trainee RPE-E ranged from 1.03 to 1.25. Conclusions:Results suggest participants were able to differentiate RPE-E and RPE-D and that the reliability for both trainee measures of RPE-E and RPE-D, in addition to trainer RPE-E is acceptable. Further, trainer RPE-E appeared to have acceptable validity compared to trainee RPE-E. These scales might be adopted in research examining the dose-response nature of effort upon RT outcomes and trainers might use them to inform programming.(Journal of Trainology 2017;5:1-8)
