Schilling BK, Pfeiffer RF, Ledoux MS, Karlage RE, Bloomer RJ, Falvo MJ - Parkinsons Dis (2010)

Bottom Line: There was a significant group-by-time effect for maximum leg press strength relative to body mass, with the training group significantly increasing their maximum relative strength (P < .05).Conclusions.Moderate volume, high-load weight training is effective for increasing lower-body strength in persons with PD.

ABSTRACT
Background. Resistance training research has demonstrated positive effects for persons with Parkinson's disease (PD), but the number of acute training variables that can be manipulated makes it difficult to determine the optimal resistance training program. Objective. The purpose of this investigation was to examine the effects of an 8-week resistance training intervention on strength and function in persons with PD. Methods. Eighteen men and women were randomized to training or standard care for the 8-week intervention. The training group performed 3 sets of 5-8 repetitions of the leg press, leg curl, and calf press twice weekly. Tests included leg press strength relative to body mass, timed up-and-go, six-minute walk, and Activities-specific Balance Confidence questionnaire. Results. There was a significant group-by-time effect for maximum leg press strength relative to body mass, with the training group significantly increasing their maximum relative strength (P < .05). No other significant interactions were noted (P > .05). Conclusions. Moderate volume, high-load weight training is effective for increasing lower-body strength in persons with PD.

Leg Press 1-RM adjusted for body mass (kg/kg) for TRN (Pre = 4.7 ± 1.4, Post 5.9 ± 1.6) and CNTL (Pre = 4.4 ± 1.5, Post 4.4 ± 1.4). A significant interaction effect was noted (P = .001). Post hoc analysis indicates a significant increase over time for TRN (P = .001).

Mentions: Testing included a battery of strength and functional measures. Maximum strength for the lower-body was assessed using a leg press machine (Hammer Strength, Figure 1). The maximum weight lifted, after warm-up, for one repetition was recorded as the one repetition maximum (1-RM), in accordance with the methods of Verdijk et al. [28]. This weight was then divided by body mass to generate a measure of relative strength. We propose this measure to be a good indicator of tasks that involve moving one's own body mass such as rising from a chair [6]. Strength data from the other training exercises were not recorded.
