Resistance Training Modalities (cont’d)Resistance Training Modalities (cont’d)

• Manual or Partner Resistance

– Unilateral elbow flexion/extension

– Towel leg press

– ISOM chest squeeze & wall push

– Front raise (held with opposite arm)

– Supine row (with legs) & chest press (on legs)

– Upright row (held with opposite arm)

– Shrug

– Hip adduction/abduction with arms

– Knee raise (against arms)

Manual Resistance Front Raise With Partner AssistanceManual Resistance Front Raise With Partner Assistance

• Manual or Partner Resistance (cont’d)

– Advantages

• Can be performed anywhere

• Little to no cost

• Low risk of injury

• High resistance throughout ROM

• Many individuals can train at once

• Resistance can be adjusted based on fatigue

• Adds variety to traditional RT program

• Free Weights

– Athlete must control weight freely in any direction

– Include:

• Barbells

• Dumbbells

• Plates

• Collars/clamps

• PlateMates

• Various accessories

• Free Weights: Advantages and Disadvantages

– Advantages

• Movements closer to those in athletics

• Stabilization muscles more effectively trained

• Lower cost & greater availability

• Best for Olympic lifts & variation

• Involve CON & ECC muscle actions & desired ROM

– Disadvantages

• Greater risk for injury

• Machines: Advantages and Disadvantages

– Advantages

• Lower risk of injury

• Better for some exercises that are difficult to perform with free weights (leg curl, leg extension)

– Disadvantages

• Greater risk of chronic inflammation in tendons

• Various Balls and Other Balance Devices

– Medicine balls

– Stability balls

– BOSU balls

– Balance steps

– Balance discs

– Balance pads

– Balance & wobble boards

• Movement-Specific Resistance Devices

– Power chutes: resist sprinting

– Harnesses: wrestling, mixed martial arts

– Weighted vests: resist sprinting & jumping

– Sleds: resist sprinting, plyometric drills

– Treadmills: resist sprinting

• Water and the Environment

– Buoyancy

• Upward force acting in opposite direction of gravity

• Related to specific gravity of athlete immersed in water

– Specific gravity

• Ratio of the mass of an object to its mass of water displacement

– Swimming

– Aquatic RT programs

– Hills & terrain

• Vibration Devices and Training

– Vibrations: mechanical oscillations defined by:

• Frequency

• Amplitude

– Vibrations can be added to exercise (vibration training):

• Applied directly to an exercising muscle via handheld vibrating unit

• Via vibrating platform

Injury PreventionInjury Prevention

• RT reduces injury prevention in:

– Weight room

– Athletics

– Recreation

– Activities of daily living

• Adaptations

– Increased joint stability

– Increased stiffness, cross-sectional area, & bone mineral density in tendons, ligaments, & bone

– Increased muscle balance

Safe and Effective Resistance TrainingSafe and Effective Resistance Training

• Follow general procedures

• Use common sense

• Use proper gym etiquette
