  6. 6. 10-6 Treadmills • Belt stretched between two rollers – Manual – less expensive – Motor driven – more expensive • Speed and incline changing abilities • AC or DC driven motors – AC driven treadmills operate at full speed all the time and can be dangerous when starting – DC models can be run at different speeds
  7. 7. 10-7 Stair Climbers • Levers attached to resistance device • Resistance can be provided by: – Flywheel – Hydraulic piston – Drive train – Wind resistance • Models: – Stairs are linked – Dual action (arms and legs) – Series of stairs – Computer/programming involvement Figure 10-2C
  8. 8. 10-8 Ski Machines • Offers aerobic benefits of cross-country skiing • Dependent vs. independent “skis” • Resistance: – Electromagnetic flywheel – Belt/pulley system with flywheel • Monitor for HR, resistance, speed, calories
  9. 9. 10-9 Elliptical Exerciser • Non-impact, elliptical shaped stride machine • Requires standing and striding forward or backward • Designed to change incline angle of ramp • Cost may range from $200- $3500 Figure 10-2E
  10. 10. 10-10 Rowing Machines • Designed to mimic actions of rowing a boat or sculling • Sliding seat with moveable handles to generate a rowing motion • Generates force with legs and upper body • Home and fitness club models are available

  12. 12. 10-12 • Massage: – Can be therapeutic – Used to stimulate circulation, aid in relaxation, and loosening muscles • Rubberized or inflatable suits – Pressure is said to break down fat tissue – Weight loss from a rubber suit will be due to water loss not fat • Electrical stimulating devices: – Utilize low amperage current of sufficient intensity to cause involuntary muscle contractions
  13. 13. 10-13 Spas, Steam Bath, Saunas • Widespread use in health and fitness industry • Therapeutic benefits of hot tubs/whirlpools – Relaxation – Will not result in weight loss due to fat losses • Re-hydration is critical following use due to loss of water – Must be cautious due to full body immersion • Temperature should not be above 100o F
  14. 14. 10-14 • Precautions for spas, saunas, or steam baths: – Avoid use if pregnant or have skin infections – Do not use any of these without cooling down after exercise – Wash off all oils or lotions before use – Never drink alcohol before use – If you feel faint, get out immediately – Always have someone with you when using any of these

  16. 16. 10-16 How should you choose appropriate clothing and shoes for exercise? • Clothing for exercise in hot, humid conditions: – Should allow for maximal dissipation of heat through sweat evaporation – Minimize heat gain from the environment – If sweat remains on the skin, heat loss will not occur
  17. 17. 10-17 • Clothing for exercising in cold weather: – Goal is to produce semi-tropical environment to prevent chilling – Should not restrict motion or limit heat exchange – Should be lightweight clothing that can be layered, allowing for changing temperatures – May need additional clothing during warm-up – Hat and gloves are also useful in maintaining heat
  18. 18. 10-18 Shoe Selection • Toe box: – Come in varying widths – Be aware of friction or pressure • Sole: – Should absorb shock and be durable – Should provide good traction • Heel counters: – Prevents medial and lateral roll of foot • Arch support: – Durable but soft and supportive to foot Figure 10-5
  19. 19. 10-19 What do you look for when shopping for a health club? • Easy to get caught up in the health club industry hype • Should offer good instruction in an aesthetically pleasing environment • You do not need to join a health club/gym or hire a personal fitness trainer to achieve fitness goals – May not be affordable for most college students
