Chapter 10
Balance-Training Concepts
Purpose
• To provide the fitness professional with a fundamental level of knowledge regarding the use of balance stabilization training concepts
• To allow the fitness professional to select and administer the appropriate balance-training protocol for all clients
Objectives
• After this presentation, the participant will be able to:– Define balance and describe its role in performance and
injury risk.– Discuss the importance of balance training. – Design a progressive balance-training program for clients in
any level of training.– Perform, describe, and instruct various balance-training
exercises.
Concepts in Balance
• The Importance of Balance– Maintaining balance is a key to all functional movements.– Often thought of as a static process
• Functional balance is static and dynamic.
– The ability to reduce force at the right joint, at the right time, and in the right plane of motion requires optimum levels of functional dynamic balance and neuromuscular efficiency.
Balance Mechanism
• Balance training should constantly stress an individual’s limits of stability (balance threshold). – Limit of stability: The distance outside of the base of support
to which the client can go without losing control of his or her center of gravity
– This threshold must be constantly stressed in a multiplanar, proprioceptively enriched environment using functional movement patterns.
Balance Mechanism
• Proprioceptively Enriched Environments– Unstable yet controllable environment– Must use the appropriate progressions and correct
technique at varying speeds to facilitate maximal sensory input to the central nervous system
– Proper progression• Floor
• Balance beam
• Half foam roll
• Foam pad
• Balance disc
Scientific Rationale
• Benefits– Improves dynamic joint stabilization
• The ability of the kinetic chain to stabilize a joint during movement
– The main goal is to continually increase the client’s awareness of his or her limit of stability (kinesthetic awareness) by creating controlled instability.
Balance and Joint Dysfunction
• Muscle imbalances, joint dysfunctions, pain, and swelling can lead to altered balance. – 80% of the adult population experiences low-back pain.– 80,000–100,000 anterior cruciate ligament (ACL) injuries
occur annually. – More than two million ankle sprains occur every year. – Thus, the majority of the clients that fitness professionals
work with may have decreased neuromuscular efficiency and balance.
Balance and Joint Dysfunction
Balance Training Effects on Injury
• Balance exercises are a frequent component of integrated ACL injury prevention programs, which have shown promise in reducing the rate of ACL injury– On the basis of a recent systematic review, balance training
programs performed for at least 10 minutes a day, 3 times per week for 4 weeks, appear to improve both static and dynamic balance ability.
Designing a Balance Program
• Exercise Selection– Safe– Progressive
• Easy to hard
• Simple to complex
• Known to unknown
• Static to dynamic
– Proprioceptively challenging• Floor
• Balance beam
• Half foam roll
• Foam pad
Variables
• Plane of motion– Frontal– Sagittal– Transverse
• Range of motion– Full– Partial– End-range
Levels of Balance Training
• There are three levels of training within the National Academy of Sports Medicine’s OPT™ model– Stabilization– Strength– Power
Balance Stabilization Exercises
• Exercises involve little joint motion and are designed to improve reflexive joint stabilization contractions to improve joint stability. – When the body is placed in
unstable environments, it must react by contracting the right muscles at the right time to maintain balance.
Balance Strength Exercises
• More dynamic eccentric and concentric movement through a full range of motion
• Require dynamic control in mid-range of motion with isometric stabilization at the end-range of motion
Balance Power Exercises
• Develop high levels of eccentric strength, dynamic neuromuscular efficiency, and reactive joint stabilization
Implementing a Balance Program
• Stabilization Level (Phase 1)– Select balance stabilization exercises.
• Strength Level (Phases 2, 3, and 4)– Select balance strength exercises.
• Power Level (Phase 5)– Select balance power exercises.
Program Design
Summary
• A balance-training program is designed to ensure optimum neuromuscular efficiency of the entire kinetic chain.
• Balance-training programs must be systematic and progressive, following specific guidelines, proper exercise selection criteria, and detailed program variables.
• A proper balance-training program follows the same systematic progression as the OPTTM model: stabilization, strength, and power.
