“…Also, a potentiometer, coupled to the rotational axis of the mechanical arm of the knee extension machine, provided real-time biofeedback on a computer screen as to the ROM excursed by each volunteer. The use of a potentiometer to analyze the ROMs excursed during tests and training were described in previous studies of our group (Diniz et al, 2020;Lacerda et al, 2021).…”

The study compared changes in strength and regional muscle hypertrophy between different ranges of motion (ROM) in the knee extension exercise. Forty-five untrained women were randomized to either a control group or to perform the exercise in one of the following 4 groups (0°=extended knee): Full ROM (FULL ROM : 100°−30°of knee flexion); Initial Partial ROM (INITIAL ROM : 100°−65°); Final Partial ROM (FINAL ROM : 65°−30°); Varied ROM (VAR ROM : daily alternation between the ROM of INITIAL ROM and FINAL ROM ). Pre-and post-training assessments included one repetition maximum ( 1RM) testing in the ROM corresponding to the initial, final and full ROM, and measurement of cross-sectional areas of the rectus femoris and vastus lateralis muscles at 40%, 50%, 60% and 70% of femur length in regard to regional muscle hypertrophy. Results showed that the INITIAL ROM group presented a greater relative increase than all groups at 70%, and at 50% and 60% the increases were greater than FINAL ROM , FULL ROM , and non-training control (CON) groups. Moreover, FINAL ROM group presented similar changes compared to the CON group at 60% and 70%. In regard to 1RM, FINAL ROM and INITIAL ROM groups presented greater relative increases at the ROM trained, and no group showed greater increases than VAR ROM or INITIAL ROM , regardless the ROM tested. In conclusion, partial ROM training in the initial phase of the knee extension exercise promoted greater relative hypertrophy in certain muscle regions than training in other ROM configurations, and no group promoted a greater 1RM increase than VAR ROM group, which showed similar 1RM increases in the different ROMs tested.

“…Finally, muscular cross-sectional area (CSA) adaptations were extensively studied in both population groups. The highest values were recorded in the training cadences with ECC MAD equal to CON MAD (+3.4-27.0%) in untrained subjects (5,7,34,55,57) with the higher values in cadence 1-2/0/1-2/0 (55) and those in which CON MAD was greater than ECC MAD (+4.3-25.8%) (7,19) with the higher values in cadence 2/0/6/0 (19).…”

“…The interventions in the analyzed studies comprised a total repetition MAD of between 4 and 14 seconds (1,5,7,19,34,47,48,55,57,58,60,61), with most of the investigations with a total repetition MAD of less than 7 seconds (1,5,7,34,47,48,57,58,60,61). These training prescriptions are consistent with those in the study by Schoenfeld et al (54), who found muscle hypertrophic improvements are similar when training with a total repetition MAD of between 0.5 and 8 seconds, as long as muscle failure is reached.…”

The aim of this systematic review was (a) to identify the articles that have differentiated muscle action duration (MAD) in the eccentric (ECC) and concentric (CON) muscle action regimen during resistance training (RT) programs and (b) to analyze how MAD affects strength, power, and muscle hypertrophy adaptations. Twenty-four studies were included from 3 electronic databases. The results showed that the RT protocols with medium ECC MAD and fast CON MAD, specifically cadences 2–4/0/1/0, produced the highest improvement values for the development of maximum dynamic strength, both in trained (18–24%) and untrained subjects (10–14%). For the development of maximum power, a medium total repetition MAD of less than 4 seconds and slow total repetition MAD, less than 8 seconds, seems suitable for untrained and trained subjects, respectively, with the condition that CON MAD is explosive or fast (cadence 4–8/0/max-3/0). Finally, muscle hypertrophy could be improved with a total repetition MAD less than 8 seconds in both trained and untrained subjects. The optimal timing of each muscle action to maximize hypertrophic training results is still not entirely clear. In conclusion, the prescription of the MAD, total and phase specific, should be planned according to the adaptations desired in untrained and trained individuals.

“…In other words, recent studies have reported that instead of the training volume that was previously considered important, the impulse (training load × muscular exertion duration) during training might be an important factor. However, a previous study that compared the training effects of two protocols with the same training load and different impulses demonstrated no difference in the training effect 19) ; thus, further studies on impulse are necessary.…”

This study conducted a secondary survey based on the hypothesis that the "total mechanical activation of fast-twitch fibers in the muscles determines the effects of muscle hypertrophy", with resistance training of the knee extensor muscles as the target because of its importance in preventing sarcopenia. Using a mathematical model that estimates the mechanical activation of each muscle fiber (fast-twitch and slow-twitch fiber) during exercise, which was developed in a previous study, we estimated the total mechanical activation of fast-twitch fibers in 30 training programs described in 23 selected previous studies on leg extension exercise programs and their muscle hypertrophy effect. With the estimated value and other factors of the training effect described in previous studies (training volume, etc.) as explanatory variables and muscle hypertrophy effect as an objective variable, we performed multiple regression analysis. The results revealed that the training effect was related to total mechanical activation of the fast-twitch fibers (standardized partial regression coefficient: 0.66), training load (standardized partial regression coefficient, 0.29) and number of sets (standardized partial regression coefficient: −0.37). The total mechanical activation of fast-twitch fibers was the strongest determinant of the muscle hypertrophy effect. In addition, we predicted the relationship between the level of the training effect of leg extension exercise and program variables. This study is the first to demonstrate "the relationship between total mechanical activation of fast-twitch fibers and muscle hypertrophy effect" in the field of muscle physiology, and the first to elucidate the association between the program variables and the training effect.
