  1. Plan for Week 7 (Oct 5 & 7) • Tuesday • Review exam • Review powerpoint on resistive exercise equipment • Thursday • Visit rec center • Derek Walters, Associate Director

  2. Cost of Aerobic Exercise Equipment at Rec Complex • Stationary Bicycles • Uprights $1436-$2471 • Recumbents $1798-$3634 • Treadmills $4695-$7995 • Rowers $680 • Stepping machines $1779-$3199 • Elliptical $2850-$4000 • Cybex Arc Trainer ($4600.00) LifeFitness • CrossTrainer ($3995.00) SciFit Total Body

  3. Methods for Resistive Equipment Selection • Apply relevant scientific principles to evaluate claims • Biomechanical • Physiological • Psychological • Use it yourself at conferences or health clubs • Product reviews in fitness magazines (Club Industry, Athletic Business, Fitness Management) • Try it yourself and take a tall or short person with you • Consult with experts who supervise its use, or other professionals (e.g., professors in area of expertise) • Look at research available, if any • Evaluate quality of research • Who sponsored research? • Peer-reviewed presentation?

  4. Relevant Questions for Resistive Equipment Selection (Criteria) • Can you apply specificity principles appropriately? • Type of contraction, movement pattern, speed • Carryover to living in gravitational environment? • Is resistance enough to accomodate your strength? • Does it fit different sized people? • Is it safe? • Is it uncomplicated to use (user friendly) • Is there scientific evidence to support manufacturer’s claims? • Does the equipment follow a normal neuromuscular pattern? • If variable resistance, does resistance follow normal strength-position curve? • Does it have motivation-enhancing features?

  5. Resistive Exercise Equipment • Simple and handy devices (plastic bottles, rubber tubing, springs) • adv - cheap, convenient • disadv - no versatility in direction, force, speed • Constant resistance training devices (free wts, body wt) • adv – convenient to use, cheap, balance needed, portable, motivation • disadv - safety, inconvenient to change wts, no versatility indirection, speed • Gravity-dependent resistance machines (circular pulleys) • adv - safety, convenient to change wts, versatility in force direction, motivation • disadv - cost, balance not required

  6. Gravity-dependent Resistance Wt Machine Concentric and eccentric contraction of agonists only!

  7. Resistive Equipment (cont’d) • Variable resistance wt machine (CAMS or roller on bar) • adv - variable resistance as well as direction of force app, motivation • disadv - cost, no versatility in speed • Isokinetic devices (same speed) • Adv - speed specific, vary force during movement (great for rehab) • Disadv - motivation, cost • Computer-assisted devices (can control either speed or resistance) • adv - variable resistance & speed, motivation, permanent record • disadv - cost

  8. Variable Resistance Weight Machine Concentric and eccentric contraction of agonists only!

  9. ComputerizedExercise Machine Agonists and antagonists Concentric contraction only!

  10. Pneumatic Resistance(air, two-way) Agonists and antagonists Concentric contraction only!

  11. Isokinetic (accomodating) Resistance (one-way) Agonists concentric contraction only!

  12. Hydraulic Resistance Agonists and antagonists Concentric contraction only!

  13. Elastic Resistance Agonists only, concentric & eccentric contraction Bowflex: Soloflex:

  14. Exercise Equipment of Questionable Value • Devices to vibrate, melt, or massage away fat • Stretching, pulling, or pushing devices • Wearing or carrying weights • Rebounders or minitrampolines - Exerlopers • Exerlopers Fitness Systems - Home Page • Healthrider: • Fitness Equipment: Index • Gazelle, or healthstrider: • Fitnessquest home page • Electrical stimulation • Electrical Muscle Stimulator

  15. Websites for Abdominal Exercise Equipment • Ace Home Page

  16. Abdominal Muscle Review

  17. Situp Exercises: Which methods are Potentially harmful? In what way?

  18. Costs of Resistive Equipment at Rec Center • Free weights • Benches $660; dumbbell set $1,300; Rack for dumbbells $585; Olumpic weight set $1,650 • Plate loaded weight machines - $1,500-$1,700 • VRI station (variable resistance one axis) - $1,700-$3,900 • VRII station (variable resistance, 2 axes) - $2,300-$4,000 • Isokinetic (accomodating resistance) - $10,000 • Computer-controlled - $20,000
