Question

(02.04 lc)
what does weight training use? (3 points)

aerobic improvements from muscle strength
flexibility of muscle control
resistance against muscle contractions
extra muscle tissue fibers

Explanation:

Weight training (resistance training) involves using resistance to challenge muscles during contractions to build strength, endurance, or mass. Let's analyze the options:

• "Aerobic improvements from muscle strength": Weight training is anaerobic, not focused on aerobic improvements. Eliminate.
• "Flexibility of muscle control": Flexibility training (like stretching) focuses on flexibility, not weight training. Eliminate.
• "Resistance against muscle contractions": This matches the definition of weight training, as it uses resistance (e.g., weights, bands) against muscle contractions to stimulate growth/strength.
• "Extra muscle tissue fibers": Weight training stimulates muscle growth (hypertrophy) by stressing fibers, but the question is about what weight training "uses" (the method), not the result. The key method is resistance against contractions.

Answer:

C. Resistance against muscle contractions
