Answer :

Final answer:

The college volleyball player's test profile suggests that her upper body strength, as indicated by her 1RM bench press is 110 lb (50 kg), may require improvement when compared to norms for college volleyball athletes. Option C.

Explanation:

To ascertain if a 145-lb (66-kg) college volleyball player's upper body strength, lower body strength, or lower body power needs improvement, we should evaluate her test profile against norms or expectations for athletes of her sport and level. Considering the given data:

  • 1RM bench press: 110 lb (50 kg)
  • 1RM back squat: 130 lb (59 kg)
  • VO2 max: 49 ml/kg/min
  • Body fat percentage: 18%
  • Vertical jump: 21 in. (53 cm)

For a female college volleyball player, the vertical jump is a good indicator of lower body power and a value of 21 inches (53 cm) shows decent explosiveness, suggesting that the lower body power may not be the primary concern.

Meanwhile, their 1RM bench press indicates their upper body strength, with the player benching 110 lb (50 kg), which seems to be on the lower end for athletes in such sports.

Therefore, without comparison to team or sports norms, the data suggests potential improvement in upper body strength.

Hence, the correct answer is: Option C.
