Designing RE Prescriptions • Acute Variables: • Choice of exercises • Order of exercises • Exercise intensity • Exercise volume • Inter-set rest intervals • Chronic Variables: • Exercise frequency • Progression /Periodization (discussed later in course)
Choice of Exercises • Choose exercises that target primary muscle groups of sport (performance), and promote balance/symmetry (injury prevention) • Machines vs. free weight exercises • Machines are easier to learn and less intimidating • Free weights might give better “performance” results. Also less costly. • Multi-joint vs. single-joint exercises • Recommendation: rely primarily on multi-joint • Muscle actions • Recommendation: for optimal gains in muscle strength and size exercises must include eccentric muscle actions
Order of Exercises • Place most important exercises first • If the client needs to increase lower-body strength, then place lower-body exercises first in the workout • ACSM Position Stand: • “Power” exercises performed before “strength” exercises • E.g., power clean before squat • Large muscle group exercises performed before small muscle group exercises • E.g., squat before calf raise • Multi-joint exercises before single-joint exercises • E.g., squat before knee extension
Exercise Volume and Intensity • Volume = Exercises x Sets x Repetitions • Intensity = Resistance (Load) • Methods of prescribing volume and intensity: • X repetitions at Y% 1-RM • X-RM • X repetitions at Y RPE • X repetitions using a load based on analysis of training logs
Prescribing Volume and Intensity • The best strength coaches individualize training for athletes • Requires logging workout performances (preferably electronically) • Requires analyzing training logs • For the purposes of this class, we will utilize the X-RM method
Exercise Volume and Intensity • ACSM Position Stand (Volume): • Novice: 1-3 sets per exercise • Experienced: Multiple sets • ACSM Position Stand (Intensity): • Novice: 60-70% of 1RM; or 8-12RM • Advanced: 80-100% of 1RM; or 1-6RM
Rest Intervals • If goal is strength/power, then rest ~2-3 min between sets • Strength/power gains will be attenuated if rest intervals are too short • For assistance exercises, 1-2 min should suffice • If goal is muscular endurance, then rest ≤ 1 min between sets
Exercise Frequency • Frequency = # of sessions per week • ACSM Position Stand: • Novice: 2-3 days/week (appropriate for most people) • Intermediate: 3-4 days/week • Advanced: 4-7 days/week • Remember: you get stronger between work-outs, not during • Importance of recovery
Objectives • Overview the physiological basis of periodization • Define key terms related to periodization • Introduce basic concepts of periodized exercise prescriptions
Physiological Basis of Periodization • The body’s response to “stress” (exercise) is described by the General Adaptation Syndrome (GAS) and Supercompensation (SC) Theory • GAS and SC are similar methods used to describe the same process: responses and adaptation to stress
Applying GAS/SC to S&C • A scientifically based exercise prescription can significantly improve performance in a relatively short period of time • Consequences of a training program that is monotonous (doesn’t change over time) or utilizes insufficient recovery: • Plateau in performance (best case scenario) • Decrease in performance • Injury from overuse (worst case scenario)
Periodization Terminology • Macrocycle: Typically, a year-long training plan • Phases: • Preparatory phase (off-season) • Transition phase (pre-season) • Competition phase (in-season) • Transition phase (post-season) • Mesocycle: A training cycle that addresses specific training goal(s) (e.g., maximizing strength) and usually lasts ~2-8 weeks • Microcycle: Typically, one week of training
Periodization • In general, as the athlete progresses from the post-season to the in-season, the training priorities shift from: • Non-specific activities to Sport-specific activities • High-volume/low-intensity to High-intensity/low-volume
Pre-Season Post-Season Off-Season In-Season
