PURPOSE To compare the effects of velocity-based training (VBT) vs percentage-based training (PBT) on strength, speed, and jump performance in academy rugby league players during a 7-wk in-season mesocycle. METHODS A total of 27 rugby league players competing in the Super League U19s Championship were randomized to VBT (n = 12) or PBT (n = 15). Both groups completed a 7-wk resistance-training intervention (2×/wk) that involved the back squat. The PBT group used a fixed load based on a… 

Superior Changes in Jump, Sprint, and Change-of-Direction Performance but Not Maximal Strength Following 6 Weeks of Velocity-Based Training Compared With 1-Repetition-Maximum Percentage-Based Training.

TLDR
Both training methods improved 1RM and COD times, but PBT may be slightly favorable for stronger individuals focusing on maximal strength, whereas VBT was more beneficial for PV-CMJ, sprint, and C OD improvements.

Traditional Versus Velocity-Based Resistance Training in Competitive Female Cyclists: A Randomized Controlled Trial

TLDR
In conclusion, the addition of a short-term intervention of VBRT or TRT to the usual training regimen of competitive female cyclists improves muscle strength/power, albeit V BRT might induce superior gains on maximum strength/ power for the hip thrust exercise.

Velocity-Based Resistance Training on 1-RM, Jump and Sprint Performance: A Systematic Review of Clinical Trials

TLDR
According to the results of the analyzed studies, it is not necessary to reach high muscle failure in order to achieve the best training results and the fact that it is possible to optimize exercise adaptations with less fatigue is reinforced.

The Role of Velocity-Based Training (VBT) in Enhancing Athletic Performance in Trained Individuals: A Meta-Analysis of Controlled Trials

Velocity-based training (VBT) is a rising auto-regulation method that dynamically regulates training loads to promote resistance training. However, the role of VBT in improving various athletic

Load-velocity relationship of the deadlift exercise

TLDR
This finding provides an alternative to the demanding, time-consuming and interfering 1RM tests, and allows the use of the deadlift exercise following the VBT principles.

The Implementation of Velocity-Based Training Paradigm for Team Sports: Framework, Technologies, Practical Recommendations and Challenges

TLDR
Guidelines to combine velocity metrics with subjective scales to prescribe training loads are presented, as well as methods to estimate 1-Repetition Maximum (1RM) on a daily basis using individual load–velocity profiles.

Analysis of the associations between variables derived throughout velocity-based training device and jumping performances in youth soccer players: Multiple regression study

Background: It has been suggested that velocity-based training (VBT) improves real-life performance in sports, such as jumping, but studies rarely examined the associations between variables derived

The Training of Medium- to Long-Distance Sprint Performance in Football Code Athletes: A Systematic Review and Meta-analysis

TLDR
Subgroup analysis identified that football code, age, and phase of season moderated the overall magnitude of training effects and secondary, tertiary, and combined training methods appeared to improve medium-long sprint performance of football code athletes.

Test-Retest Reliability and Validity of the Velocity- Based Training Device for Measuring Kinetics and Kinematics Variables in Youth Soccer Players

Velocity-based training (VBT) is a popular method for prescribing and monitoring resistance-training load. The aim of this study was to investigate the reliability and validity of the PUSH band for

Effects of Velocity Loss During Resistance Training on Performance in Professional Soccer Players.

TLDR
A velocity-based RT program characterized by a low degree of fatigue (15% velocity loss in each set) is effective to induce improvements in neuromuscular performance in professional soccer players with previous RT experience.

TLDR
It is suggested that high overall playing intensity and match loads in end-season matches increase in injury rates in the latter half of the season, and residual fatigue associated with limited recovery between successive matches may compromise the physical development of rugby league players.

EFFECT OF DIRECT SUPERVISION OF A STRENGTH COACH ON MEASURES OF MUSCULAR STRENGTH AND POWER IN YOUNG RUGBY LEAGUE PLAYERS

TLDR
Findings show that the direct supervision of resistance training in young athletes results in greater training adherence and increased strength gains than does unsupervised training.

Effects of velocity loss during resistance training on athletic performance, strength gains and muscle adaptations

TLDR
The progressive accumulation of muscle fatigue as indicated by a more pronounced repetition velocity loss appears as an important variable in the configuration of the resistance exercise stimulus as it influences functional and structural neuromuscular adaptations.

Are Changes in Maximal Squat Strength During Preseason Training Reflected in Changes in Sprint Performance in Rugby League Players?

TLDR
It is likely that the increased force production, noted via the increased squat performance, contributed to the improved sprint performances, which should be considered to increase short sprint performance.

Comparison of the Effects of Velocity-Based Training Methods and Traditional 1RM-Percent-Based Training Prescription on Acute Kinetic and Kinematic Variables.

PURPOSE To compare kinetic and kinematic data from 3 different velocity-based training sessions and a 1-repetition-maximum (1RM)-percent-based training (PBT) session using full-depth, free-weight

Influence of Fatigue on Tackling Ability in Rugby League Players: Role of Muscular Strength, Endurance, and Aerobic Qualities

TLDR
It is suggested that lower-body strength protects against fatigue-induced decrements in tackling ability, and should be a priority to facilitate the development of robust tackling skills that are maintained under fatigue.

Effect of Strength and Power Training on Tackling Ability in Semiprofessional Rugby League Players

TLDR
It is demonstrated that the enhancement of lower-body muscular strength, and to a lesser extent muscular power, contribute to improvements in tackling ability in semiprofessional rugby league players.

Validity of Various Methods for Determining Velocity, Force, and Power in the Back Squat.

TLDR
PUSH accuracy for determining MV, PV, MF, MP, and PP across all 6 relative intensities was questionable for the back squat, yet the GYM was highly valid at assessing all criterion variables, with some caution given to estimations of MP and PP performed at lighter loads.

Neuromuscular Fatigue and Recovery after Heavy Resistance, Jump, and Sprint Training

TLDR
Strength, jump, and sprint training requiring repeated maximum efforts elicits fatigue that requires up to 72 h to fully resolve, but this fatigue is not primarily underpinned by decrements in CNS function.
