A brand of footwear claims to have created a new design to help consumers lose weight by burning fat and building muscle as the wearer walks. The manufacturer claims the inclined sole in the shoes will reduce foot and ankle injury while it doubles the fat-burning effects of walking in regular sneakers. They also claim that those who wear their shoes for 30 minutes of walking every day will increase their endurance and enhance the aerobic effects of exercise.
Which of the following, if true, most seriously undermines the claims of the footwear designer?
Claims are for?
- Weight loss
- Muscle improvement
- Reduce injury
A. Clinical trials have shown that inclined soles tend to cause undue stress on the Achilles tendon, a potentially painful and debilitating injury.
Violates the injury claims. Hence the answer
B. Studies show that 30 minutes of daily walking will increase muscle mass in the calf, creating a more efficient metabolic rate in the breakdown of body fat.
Supports the claims of the manufacturer
C. It can be mathematically calculated that the angle of incline of the sole of the shoe is directly proportional to pronation of the metatarsal bones of the forefoot.
Supports the claims of the manufacturer
D. Exercise, especially walking, has been shown to have significant health benefits, especially for the elderly, who tend to have a more sedentary lifestyle.
Supports the claims of the manufacturer
E. The American Association of Medical Experts states that walking for 30 minutes every day has little impact on prevention of heart disease.
The claim of manufacturer is for endurance and not prevention of heart disease, doesnt affect.
