Summary

The investigators are doing this research study to compare whole body aerobic training with isolated leg training (with weights) and its impact on effectiveness in symptoms and quality of life in patients with Pulmonary Arterial Hypertension (PAH).

Conditions

Interventions

BEHAVIORAL

Aerobic Training

Aerobic training will be conducted at 30 minutes 3 times a week using brisk walking with target heart rates goals based on percentage of peak HR reserve (HRR= peak-rest HR) during baseline exercise right heart catheterization (RHC). The target HR will progress over the study period from 50% to 70% of peak HR reserve added to resting HR using the standard Karvonen formula (Goal HR = rest HR + target % of HRR). HR will be monitored using Fitbits to guide training intensity with raw data analyzed using the Fitabase platform to monitor compliance

BEHAVIORAL

Leg Training

Leg training will be performed using assigned ankle weights to perform knee extension while seated. Initial weight assignment will be guided by a protocol driven in-person exercise tolerance test using varying weights to identify the optimal initial and target training weight for each patient based on the 10 repetition maximum weight identified during this test. Leg training weight will begin at 40% of the baseline 10-repetition maximum weight for weeks 1-4 during which time patients will be required to complete 3 sets of 10 repetitions (30 repetitions total) on 3 days per week. For weeks 4-8, 55% of the initial 10-repetition maximum weight will be used for 4 sets of 10 repetitions (40 repetitions total). For weeks 8-12, 70% of the initial 10-repetition maximum weight will be used for 5 sets of 10 repetitions (50 repetitions total).
