A

False
Fat should account for 20 25% of Total Energy Intake to support CHO requirements. This means that the minimum amount of fat that an athlete who requires 2725 kcal/day is .20 X 2725 kcal = 545 kcal from fat/9 kcal per gram of fat = 60.5 grams of fat per day.

A

False
The DSM-V has clear criteria to support the diagnosis of anxiety and anxiety disorders. The DSM-V does not support diagnosis of Orthorexia Nervosa because this condition is not considered to be an eating disorder at this time. It is a sub-clinical form of disordered eating. Health care providers would still be concerned about the behaviours that are commonly associated with Orthorexia Nervosa. However, it is important to understand that Orthorexia Nervosa is not a recognized eating disorder with agreed-upon diagnostic criteria in the DSM-V.

78
Q

An athlete’s estimated Total Daily Energy Intake is 3650 kcal. To support weight loss, the recommended energy intake for this athlete should be between 2650 and 3150 kcal/day.

A

True

80
Q

Professional dominance refers to the understanding that non-health professional members of an Integrated Support Teams (IST), such as coaches or team managers, typically have less influence over the adoption of recommendations for athlete health than the trained health professionals on the same team.

A

false
Professional dominance describes the structural relationships different professions have with one another in relation to power imbalances, issues of trust, suppression of competing professions, and subordination of less established professions. Research shows that coaches, while not trained as health professionals, still exert significant professional dominance on an IST, which can create issues between the team members.

81
Q

The Long-Term Athlete Development framework for a sport provides the requirements for ratios of training to competition hours, points of emphasis in skills training, formats for competition, and nutrition education.
