Acute effects of different set configurations during a strength-oriented resistance training session on barbell velocity and the force–velocity relationship in resistance-trained males and females

Effect of Inter-Repetition Rest vs. Traditional Resistance Training on the Upper Body Strength Rate of Force Development and Triceps Brachii Muscle Architecture

“…However, inter-repetition rest training induced higher percentage increases in the early RFD compared to traditional resistance training. This result may partially be explained by the potential advantage of the interrepetition rest training in maintaining a high velocity of movement in each repetition (Torrejón et al, 2019) After seven weeks of training, significant increases were observed in triceps brachii muscle thickness for both the IRRG and TRG. The bench press is a multijoint exercise which includes the activation of pectoralis (pectoralis major, pectoralis minor), deltoid (medial and anterior deltoid) and arm muscles (long intern and extern portions of triceps brachii).…”

“…The aim of the current study was to compare inter-repetitions rest vs. traditional resistance training on upper body strength, the RFD and triceps brachii muscle architecture in physically active participants. Based on the acute and chronic benefits of inter-repetition rest training on upper body strength and velocity (Inglesias-Soler et al, 2014;Torrejón et al, 2019) Maximum strength in the bench press was significantly increased for both groups. Interrepetition rest training, however, induced higher percentage increases compared to traditional training, which is supported by a previous study (Oliver et al, 2013).…”

“…15-45 s) between single repetitions or after clusters of 2-3 repetitions in a single set, may result in faster adenosine triphosphate (ATP) resynthesis and lower concentration of muscle lactate, which allows the use of higher training intensity/volume and finally, greater longitudinal increases in muscle strength ( Haff et al, 2008 ; Iglesias-Soler et al, 2012; Nickolson et al, 2016). Indeed, this resistance training strategy allows for a higher total training intensity and volume compared to traditional resistance training which may also result in greater increases in velocity and power production (Inglesias-Soler et al, 2014; Torrejón et al, 2019 ).…”

Current and Future Trends in Strength and Conditioning for Female Athletes

“…Interestingly, female athletes have shown higher barbell velocity when performing heavy loads on bench press compared to males. However, females showed lower barbell velocity when performing lighter loads on bench press compared to males [ 81 ].…”

“…Maintaining velocity throughout the training session in strength-based phases is important as training at higher velocities rather than lower velocities can lead to greater strength gains [ 83 ]. The greatest difference in average training velocity using the bench press was observed in the last repetitions of the set [ 81 ], suggesting that velocity may decrease as repetitions increase for the bench press. Furthermore, the addition of longer intra-set rest periods may aid in recovery between sets to combat this fatigue, although future research is needed to further support this, especially among females.…”
