“…These equations are derived from the heaviest possible load the subject is able to lift for a predetermined number of repetitions, a given load for as many repetitions as it is possible in a predetermined time or, inducing fatigue within a specific range of repetitions (Chapman, 1998). Therefore many prediction methods common in strength training practice employ exhaustive efforts.…”

Movement velocity as a measure of exercise intensity in three lower limb exercisesMovement strength velocity and intensity KEY WORDS: Resistance training, movement velocity, strength. ABSTRACTThe purpose of this study was to investigate the relationship between movement velocity and relative load in three lower limbs exercises commonly used to develop strength: Leg Press, Full Squat, and Half Squat. The percentage of one Repetition Maximum (%1RM) has typically been used as the main parameter to control resistance training, however more recent research has proposed movement velocity as an alternative.Fifteen participants performed a load progression with a range of loads until they reached their one repetition maximum (1RM). Maximum instantaneous velocity (Vmax) and mean propulsive velocity (MPV) of the knee extension phase of each exercise were assessed.For all exercises, a strong relationship between Vmax and the %1RM was found: Leg Press (r 2 adj =0.96; 95% CI for slope is [-0.0244 Results indicate that it is possible to determine an exercise-specific %1RM by measuring movement velocity for that exercise.

“…A carga submáxima foi obtida a partir do teste de 8-12 RM e, em alguns casos, o número de repetições realizados foi superior a 10. Alguns estudos têm indicado que testes submáximos realizados com até 10-RM proporcionam melhores estimativas de 1-RM [27][28][29] . Entretanto, no presente estudo, esses casos foram pontuais e a exclusão desses indivíduos não promoveu alteração nos resultados.…”

“…1RM testing may be a concern even for a trained population of athletes. This is because frequent measurements are needed to assess strength gains over time, which may interfere with the current training program given the considerable amount of time required per test per muscle group 12) . For example, in a study by Chapman et al (1998) 12) , a 1RM bench press test for 98 subjects took six hours for three staffers to complete using five bench press stations.…”

“…Extrapolation of one's 1RM is also possible with submaximal liftings, reducing many of the associated concerns related to a 1RM test. A number of different equations have been reported for the repetition-intensity relationship or the prediction of 1RM; with the data being fitted by either linear, exponential, inverse or power functions 7,8,[12][13][14] (Table 1). When heavier loads are used (10RM or heavier), the predicted intensities are close to an agreement among the equations, and 1RM values well predicted (within an average of 5.7 kg).…”

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.
