“…Given the information above, it can be postulated that load would be associated with effort when all other variables are maintained constant. Alternatively, the higher sRPE for the LIT could also be related to greater time under tension during the exercises, as indicated by Diniz et al [25], who compared different repetition-matched RT protocols and noted a higher sRPE when exercises were performed with longer repetition durations.…”

The main purpose of the present study was to investigate the acute effects of different training loads on ratings of perceived exertion and discomfort and feelings of pleasure/displeasure in resistance-trained men. Twelve resistance-trained men (26.7±3.5 years, 85.1±17.5 kg, and 174. 9±9.9 cm) performed 3 sets of the bench press, squat on a hack machine, and lat pulldown, until volitional concentric failure in two separate conditions: a moderate load (MOD) consisting of a relative load of 8–12 repetitions maximum (RM), and a light load (LIT) consisting of a relative load of 25–30RM. The session rating of perceived exertion (sRPE), session rating of perceived discomfort (sRPD), and session pleasure/displeasure feelings (sPDF) were assessed after 15 min after the ending of each session. A randomized, counterbalanced, crossover study was performed with 48 h recovery afforded between sessions. Differences between conditions were observed for sRPE and sRPD, in which scores for LIT were greater than MOD (sRPE: MOD=5.5±1.0 vs. LIT=6.4±0.7; sRPD: MOD=6.7±1.7 vs. LIT=8.7±1.0). For sPDF, MOD reported feelings of pleasure (1.2), whereas the LIT presented a feeling of displeasure (–2.3). Results suggest that resistance training performed with a light load until failure induces higher degrees of effort, discomfort and displeasure compared to a moderate load.

“…Furthermore, the deliberate slowing of the ECC muscle action may limit the contribution of the stretch-shortening cycle (SSC), which may result in a reduced transfer of training effects to sporting performance. Finally, slower ECC actions have demonstrated greater perceived effort and lactate accumulation, which may make the inclusion of TEMPO inappropriate during specific times in the annual plan [12][13][14][15].…”

“…As purposefully lengthening the ECC phase may result in a lower number of achieved repetitions compared to a self-selected pace, the loading intensity may need to be lowered to complete the prescribed set and repetition scheme [19,20]. Additionally, attention should be paid to the response to this loading, which may result in higher acute fatigue and the athlete perceived exertion during the session [12][13][14]. It should be noted that although the number of repetitions may decrease with a longer ECC phase, the TUT increases [21].…”

The purpose of this review is to provide strength and conditioning practitioners with recommendations on how best to implement tempo eccentric training (TEMPO), flywheel inertial training (FIT), accentuated eccentric loading (AEL), and plyometric training (PT) into resistance training programs that seek to improve an athlete’s hypertrophy, strength, and power output. Based on the existing literature, TEMPO may be best implemented with weaker athletes to benefit positional strength and hypertrophy due to the time under tension. FIT may provide an effective hypertrophy, strength, and power stimulus for untrained and weaker individuals; however, stronger individuals may not receive the same eccentric (ECC) overload stimulus. Although AEL may be implemented throughout the training year to benefit hypertrophy, strength, and power output, this strategy is better suited for stronger individuals. When weaker and stronger individuals are exposed to PT, they are exposed to an ECC overload stimulus as a result of increases in the ECC force and ECC rate of force development. In conclusion, when choosing to utilize ECC training methods, the practitioner must integrate these methods into a holistic training program that is designed to improve the athlete’s performance capacity.

“…O limite superior da amplitude de movimento foi determinado até a extensão completa dos cotovelos e o limite inferior foi determinado por meio de uma borracha fixada sobre a região do esterno. Foi realizada ainda a familiarização dos voluntários ao teste de 1RM com até seis tentativas para identificar o peso máximo que o voluntário poderia levantar em uma única repetição 4,19 com uma pausa de três a cinco minutos entre as mesmas. Em seguida procedeu-se a familiarização às durações das ações musculares: 4-2 (4s concêntrica e 2s excêntrica); 3-3 (3s concêntrica e 3s excêntrica); 2-4 (2s concêntrica e 4s excêntrica) de forma aleatória e balanceada entre os voluntários no decorrer das sessões 1 e 2.…”

RESUMOO objetivo deste estudo foi comparar a concentração de lactato sanguíneo em protocolos de treinamento de força com diferentes durações das ações musculares no exercício supino. Dezessete voluntários executaram três protocolos com três séries de seis repetições a 60% de 1RM, pausa de três minutos entre as séries e diferentes durações das ações musculares (2-4: 2s concêntrica e 4s excêntrica; 3-3: 3s concêntrica e 3s excêntrica; 4-2: 4s concêntrica e 2s excêntrica). A análise da concentração de lactato sanguíneo considerou os valores médios por série em cada protocolo. Os resultados da ANOVA two-way mostraram que o efeito principal protocolo não apresentou diferença significante entre os três protocolos (F = 0,75; p = 0,48; poder = 0,48; η 2 = 0,17), assim como para a interação entre os fatores (F = 1,68; p = 0,13; poder = 0,09; η 2 = 0,62). Porém, houve diferença significante na concentração de lactato sanguíneo para o fator série (F = 320,23; p = 0,0001; poder = 1,00; η 2 = 0,95). Portanto, protocolos de treinamento de força equiparados com durações das ações musculares distintas não apresentaram diferenças na resposta do lactato sanguíneo e, independentemente do protocolo, a concentração deste substrato aumentou ao longo das três séries realizadas. Palavras-chave: Treinamento de força. Duração da repetição. Lactato sanguíneo. ABSTRACTThe aim of this study was to compare the blood lactate concentration in strength training protocols with different muscle action durations in the bench press exercise. Seventeen volunteers performed three protocols with three sets of six repetitions at 60 % of 1RM, three-minute break between sets and different muscle action durations (2-4: 2s concentric and 4s eccentric; 3-3: 3s concentric and 3s eccentric; 4-2: 4s concentric and 2s eccentric). The analysis of blood lactate concentration considered the average values per set in each protocol. The ANOVA two-way of the results showed that the main effect for protocol showed no significant difference between the three protocols (F = 0,75; p = 0,48; power = 0,48; η 2 = 0,17), as the interaction among the factors (F = 1,68; p = 0,13; power = 0,09; η 2 = 0,62). However, there was significant main effect for set (F = 320,23; p = 0,0001; power = 1,00; η 2 = 0,95). Therefore, resistance training protocols equated with different muscle actions durations shows no differences in blood lactate response and, regardless of the protocol, its concentration increased throughout the three sets performed. Keywords: Resistance training. Repetition duration. Blood lactate. IntroduçãoO lactato sanguíneo é um subproduto do sistema glicolítico anaeróbico que tem sua concentração alterada de acordo com a exigência metabólica de um exercício 1 . A concentração de lactato sanguíneo vem sendo utilizada como um parâmetro de resposta metabólica proporcionada por diferentes protocolos de treinamento de força [2][3][4] . Estudos têm associado uma elevada resposta da concentração de lactato sanguíneo com um aumento no recrutamento de unidades motoras rápidas ...
