- 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. 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

- 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. 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
