Acute Variables: Repetition Tempo

This course discusses the optimal repetition tempo for various training goals (a.k.a. rep tempo, rep speed, rep cadence, lifting tempo, tempo training, etc.). That is, this course discusses the evidence-based ideal tempos for endurance, hypertrophy, strength, power, athletic performance, functional training, and corrective exercise. The details discussed include the effect rep tempos have on muscle adaptations, short-term and long-term hormone concentrations, post-exercise protein synthesis, muscle growth, muscle fiber type proportions, EMG activity, and ideal tempos for improving the rate of force development for athletes.

Some findings from the included systematic review resulted in counter-intuitive, or at least less conventional recommendations. For example, volume is likely more important for hypertrophy goals (increasing muscle mass), suggesting that if sets are performed with reps to failure, and each session is performed with the intent to iteratively increase volume, then slow, moderate, or max velocity concentric tempos may be used. Note, because time-under-tension is essential for increasing volume, it may be ideal to maintain slower eccentric tempos. Alternatively, research suggests that repetition tempo is the most important variable when training for peak velocity/power. Explosive tempos are not only ideal, but they are also essential for improving power.

Movement professionals (personal trainers, fitness instructors, physical therapists, athletic trainers, massage therapists, chiropractors, occupational therapists, etc.) should consider acute variables essential knowledge for optimal exercise programming, and rep tempo is one of those acute variables. This course is part of our continued effort to optimize “acute variable” recommendations.

Repetition Tempo Recommendations

Tempo Abbreviations:

• (Eccentric: Isometric: Concentric)
• Numbers representing seconds
• MaxV = Maximum velocity
• The most influential variable is in parantheses

Goal

• Activation Exercises: 2-4: 2-4: MaxV or explosive (range of motion, volume)
• Endurance: 2+: 0-2: MaxV or longer (volume per set)
• Hypertrophy: 2+: 0-2: MaxV or longer (volume per routine, reps until failure/set, load)
• Functional Strength: 2+: 0-2: MaxV: (velocity, volume per routine)
• Max Strength: lifter's preference: 0: MaxV (load) - Note that slower tempos may be appropriate for improvements in strength at slower velocities.
• Power: Explosive: 0: Explosive (speed) - Explosive tempos include a quick pre-stretch, the shortest amortization phase possible, and a concentric contraction with the intent to release or leave the ground.

Repetition Tempos Short Hand

• Activation Exercises: 2:4:maxV
• Endurance: 2+:0-2:maxV+
• Hypertrophy: 2+:0-2:maxV+
• Functional Strength: 2+:0-2:maxV
• Maximum Strength: V:0:V (or event-specific tempo)
• Power: Explosive
  • # indicate seconds
  • "+" indicates "or longer"
  • maxV = max velocity
  • V = volitional or lifter's preference
