Conclusion Although data are limited , there is a strong significant relationship between plantar flexor muscle strength and treadmill walking ability .
Background and Objective Exercise is a widely accepted treatment known to improve walking ability in persons with peripheral arterial disease ( PAD ) ; however , it has not been confirmed as to whether exercise improves fitness and performance-based function and , consequently , performance of activities of daily living ( ADL ) .
This systematic review aims to identify whether any mode of structured exercise improves physical fitness or performance-based tests of function and whether improvement in walking ability is related to an improvement in these outcomes .
Data Sources and Study Selection Eligible studies included r and omized controlled trials ( RCTs ) using an exercise intervention for the treatment of intermittent claudication with fitness ( including the 6-min walk ( 6MW ) , aerobic capacity , shuttle and muscle strength ) tests and performance-based tests of function as the outcomes .
Resistance training in patients with peripheral arterial disease: effects on myosin isoforms, fiber type distribution, and capillary supply to skeletal muscle.
The purpose of this study was to investigate the effects of a progressive resistance training program on myosin heavy chain isoform expression , fiber type , and capillarization in patients with symptomatic peripheral arterial disease . Patients were r and omized to either a training group ( n = 11 , mean + /- SD , 70 + /- 6 years , 4 men , 7 women ) or a control group ( n = 9 , 66 + /- 6 years , 5 men , 4 women ) . The training sessions were completed 3 times/week , using 2 sets of various exercises , each performed for 8 - 15 repetitions . Muscle biopsies were obtained before and after 24 weeks from the medial gastrocnemius . Following the 24-week training program , the training group had significantly decreased the percentage of myosin heavy chain type IIB . The proportion of type IIB/AB fibers as measured by using myosin adenosine triphosphatase histochemistry decreased significantly in the training group . There were significant increases in type I and type II fiber areas , and capillary density also increased significantly in the training group . There were significant increases in 10 repetition maximum leg press and calf press strengths in the trained subjects . There were no significant changes in any of the measurements in the control group . It is concluded that progressive resistance training results in significant increases in muscle strength and alters skeletal muscle composition of subjects with peripheral arterial disease
