Preview — answers shown1. A coach should maintain clear documentation of client progress for which purposes?
Multiple correct answersExplanation
Progress documentation tracks adherence patterns and behavioral data to identify effective strategies for each client. Measurable results guide evidence-based plan adjustments. Continuity records ensure another coach can resume support without loss of context. The primary purposes are clinical (tracking outcomes, informing adjustments) and ethical (continuity, accountability), rather than purely legal protection or personal judgment.
2. Current evidence on protein timing and distribution suggests which approach for muscle development and maintenance?
Multiple correct answersExplanation
Distributed protein intake across meals triggers repeated bouts of muscle protein synthesis, more effectively supporting muscle development than single large meals. Consuming approximately 20-40 grams of protein per meal is generally recommended for optimal muscle protein synthesis response. Post-workout protein timing provides some advantage due to elevated muscle protein synthesis rates, though magnitude is smaller than total daily protein intake. Timing is not irrelevant but is secondary to adequate total intake.
3. A male client who strength trains 5 days per week wants to build muscle mass. His caloric goal is a 300-400 kcal daily surplus above his TDEE of 2,600 kcal/day. Which macronutrient distribution strategy best supports muscle protein synthesis and training recovery?
Explanation
On a 3,000 kcal diet, this distribution provides approximately 900 kcal protein (225g), supporting 2.2-2.8 g/kg for an 80-100 kg male. Carbohydrates at 50% support training glycogen and recovery. Fat at 20% exceeds minimum requirements. This distribution prioritizes protein for muscle synthesis while maintaining adequate carbohydrate to fuel intense training sessions.
4. A client has read that consuming fat at meals is inherently unhealthy and wants to minimize all dietary fat to improve health. Which response represents an evidence-based correction of this misconception?
Explanation
Dietary fat is essential for multiple physiological functions: hormone synthesis (particularly sex hormones and glucocorticoids), absorption of fat-soluble vitamins (A, D, E, K), cell membrane integrity, and neurological function. The quality and type of fat (whole food sources, unsaturated fats, omega-3/6 balance) matters more than complete elimination. Moderate fat intake is part of sustainable, health-promoting nutrition. The outdated low-fat paradigm has been superseded by evidence supporting moderate fat consumption from quality sources.
5. A coach is working with a client who says: I'm only following this nutrition plan because you told me to, but I don't really believe in it myself. Which coaching approach best addresses autonomy and motivation concerns?
Explanation
Intrinsic motivation driven by personal values and autonomy is far more sustainable than external compliance. By exploring the client's genuine goals and values and collaboratively adapting the plan, the coach enhances autonomy and intrinsic motivation. Research on self-determination theory shows that autonomy support leads to better adherence and behavior change sustainability.
