Abstract: Objective: To determine the relationship between weight-bearing (WB) and nonweight-bearing (NWB) joint reposition sense ORS) and a functional hop test (FH) and to compare performance on these parameters between athletes and nonathletes. Design: Repeated-measures ANOVA and Pearson correlations. Setting: Research laboratory. Participants: 40 men (age = 20.8 ± 1.7 y; ht = 176.9 ± 5.8 cm; wt = 82.6 ± 9.5 kg): 20 lacrosse players and 20 nonathletes. Main Outcome Measures: Ability to actively reproduce 30° of knee flexion in the WB and NWB conditions and functional performance on a single-leg crossover-hop test. Results: No significant correlations were observed between JRS and FH in athletes and nonathletes. No significant differences were observed between athletes and nonathletes in JRS. All participants were significantly more accurate at WB than at NWB JRS. Conclusions: There appears to be no relationship between WB or NWB JRS and functional performance, regardless of one's physical activity level
