King 1995.

Methods	Randomised, controlled, parallel group trial, unblinded
Participants	169 of 357 sedentary adults, free of cardiovascular disease (aged 50‐65 years) ‐ long term follow‐up of earlier study see King 1991
Interventions	'High intensity' supervised exercise (60min predominantly aerobic, walking/jogging/cycling to 73‐88% max HR, 3 x wk) 'High intensity' home exercise (60min predominantly aerobic, walking/jogging/cycling to 73‐88% max HR, 3 x wk) 'Low intensity' home exercise (30min predominantly aerobic, walking/jogging/cycling to 60‐73% max HR, 5 x wk) and control (continued with 'usual' activity)
Outcomes	At two years treadmill performance was still significantly improved in the three exercise groups. There was no difference in outcomes between the low and high intensity groups. Participation rates were significantly better fot the high intensity home based group HDL Cholesterol levels were higher for the two home based groups and waist‐to‐hip ratios were lower.
