| Summary: | Strength training is
an effective modality to improve muscular
strength and functional performance in people
with Parkinson's disease (PWP). One-repetition maximum (1-RM) is the gold standard
assessment of strength; however, PWP suffer from
day-to-day variations in symptom severity and
performance characteristics, potentially
adversely affecting the reliability of 1-RM
performance. Herein, we assessed the reliability
of 1-RM in PWP. Forty-six participants completed
two sessions of 1-RM testing of knee extension,
knee flexion, chest press, and biceps curl at
least 72 hours apart. Significantly differences
between testing sessions were identified for
knee extension (P < 0.001), knee flexion (P = 0.042), and biceps curl (P = 0.001); however, high reliability (ICC > 0.90)
was also identified between sessions. Interestingly, almost third of subjects failed to perform better on the second testing session. These findings suggest that 1-RM testing can be safely performed in PWP and that disease-related daily variability may influence 1-RM performance. |
