“…Furthermore, if repetition velocity is habitually monitored, it is possible to determine whether the proposed load (kg) for a given training session truly represents the real effort (% 1RM) that was intended. The present findings, together with previous results for the BP and prone bench pull exercises Sánchez-Medina, González-Badillo, Pérez, & Pallarés, 2013), emphasise the practical importance of considering movement velocity for monitoring training load in resistance exercise. Nevertheless, significantly lower velocities are developed for a given relative load (especially for light and medium loads) for the STOP compared to the STRD technique in both the BP and SQ exercises (Table I).…”

“…This implies that strength and conditioning coaches should pay close attention to the exact testing protocols used when assessing the load-velocity relationship. In order to confidently interpret training or testing results, both exercise (Sánchez-Medina et al, 2013) and the particular execution technique used (STOP or STRD) should be taken into account since they greatly influence the velocity developed against a given relative load.…”

This study analysed the effect of imposing a pause between the eccentric and concentric phases on the biological within-subject variation of velocity- and power-load isoinertial assessments. Seventeen resistance-trained athletes undertook a progressive loading test in the bench press (BP) and squat (SQ) exercises. Two trials at each load up to the one-repetition maximum (1RM) were performed using 2 techniques executed in random order: with (stop) and without (standard) a 2-s pause between the eccentric and concentric phases of each repetition. The stop technique resulted in a significantly lower coefficient of variation for the whole load-velocity relationship compared to the standard one, in both BP (2.9% vs. 4.1%; P = 0.02) and SQ (2.9% vs. 3.9%; P = 0.01). Test-retest intraclass correlation coefficients (ICCs) were r = 0.61-0.98 for the standard and r = 0.76-0.98 for the stop technique. Bland-Altman analysis showed that the error associated with the standard technique was 37.9% (BP) and 57.5% higher (SQ) than that associated with the stop technique. The biological within-subject variation is significantly reduced when a pause is imposed between the eccentric and concentric phases. Other relevant variables associated to the load-velocity and load-power relationships such as the contribution of the propulsive phase and the load that maximises power output remained basically unchanged.

“…This new method eliminates the need for submaximal lifting until failure (required to establish the repetition-intensity relationship), and has been utilized in training studies to prescribe intensities, or to evaluate fatigue 4,5,21,22) . The velocity-intensity relationship, however, needs to be established per exercise like the repetition-intensity relationship 22) , and necessitates a Smith machine to ensure a smooth vertical movement, as well as a string-or cable-potentiometer to measure lifting speed. Moreover, the correct technique, the maximum propulsive effort, and consistent kinetic outflows have to be assured between trials.…”

“…Perhaps, the intermediate-velocity used during the isokinetic training coincided with or fell within the Pmax range. Despite the greater efficacy of Pmax training, there are, however, large variations in Pmax intensity among studies; ranging from 30 to 70% 1RM depending on training experience, equipment, muscles involved and/ or type of exercise 22,25,62,65) . The determination of Pmax intensity, therefore, warrants individual assessment for each exercise.…”

Isoinertial resistance is imposed during natural human dynamics, where muscles contract at varying velocities and joint angles. In many sports, the ability to produce greater force at faster speed is essential for successful outcomes. Hence, power training under isoinertial resistance (e.g., body mass, weights or flywheel, etc.) provides event-specific adaptive stimuli. Conventional power training consists of a combination of strength-oriented (> 70% 1RM) and speed-oriented (< 30% 1RM, e.g., plyometrics) methods, with the aim of being able to overcome variable external loadings across a range of velocities. An alternative maximum power output training (Pmax training, 30-70% 1RM) has been found to elicit equivalent or greater effectiveness compared to the conventional methods. It is, however, difficult to precisely reproduce the prescribed intensities, given several concerns associated with 1RM testing and the variable accuracies of the repetition-intensity or velocity-intensity relationship. No matter what level of resistance is assigned to an exercise, it is far more important to exert as much effort (or fastest concentric speed) as possible per repetition, otherwise, the training effects are reduced. At light intensities, however, a large portion of the concentric phase is spent in deceleration for the subsequent phase transition, which may limit effort. Making projectile motions, therefore, are necessary. The utilization of stretch-shortening cycle effects, with increased power ability, may give a further training edge. Coaches and trainees should be aware that successful movements in power training are defined as greater acceleration, speed and displacement for every repetition, rather than simply neat form or smooth repetitiveness.

“…The software is automatically calculates the relevant kinetic and kinematic parameters as force, power and velocity of every repetition in resistance training and displays them numerically and graphically on screen. In addition, the software provides auditory feedback and stores data on disk for analysis (18,19,34,35,36,37).…”

The basic purpose of this study was to investigate of the relationships with sprint and jump performance of velocity parameters during propulsive phase of full back squat exercise and to determine which variable was associated with which loading loading. For this purpose, thirty-two men amateur athletes (age: 20.4 ± 1.98 years; height: 179.3 ± 7.23 cm; weight: 73.5 ± 9.85 kg) who actively involved in sports and have a basic level of force participated in voluntarily to this study. In the study, one repetition maximum (1RM) full squat (SQ) strength test, vertical jump test, 5 meters and 30 meters sprint test were applied. The descriptive statistics and Pearson correlation analysis was used for statistical evaluation of datas. According to analysis results; it was obtained that mean velocity (MV), mean propulsive velocity (MPV) and peak velocity (PV) values during propulsive phase of full back squat exercise performed in different loads were decreased in parallel with load increase. In addition, it was obtained that there was no statistically a significant relationships between 5 meters sprint times and vertical jump performance with MV, MPV and PV values during propulsive phase of full back SQ exercise performed at different loads of 1RM (p > 0.05). Conversely, it was obtained that there was a mean level, negative and statistically significant relationship between 30 meters sprint times with MV during propulsive phase of full back SQ movement performed at 20 % and % 90 of 1RM load values (r = -.412; r = -.399, p < 0.05, respectively) and PV values obtained at 40 % and 60 % of 1RM load values (r = -.402; r = -.370, p < 0.05, respectively). Consequently, it was suggested that movement velocity is not an important component for performance parameters as 5 meter sprint and jumping height.
