ведь вместо бега можно
- ходить быстрым шагом
- ездить на велосипеде
- эллиптикал
- лыжи/коньки/ролики
- гребля
- плаванье/ныряние
да мало ли, перечислять можно до завтра. а еще лучше варьировать (лыжи зимой, велосипед летом)
С одной стороны, Вы правы, есть много разных вариантов упражнений. С другой стороны, получить нагрузку на сердечно-сосудистую систему такой же интенсивности, как при беге, при многих других видах упражнений достаточно сложно.
Swimming is an exercise modality that is highly suitable for health promotion and disease prevention, and is one of the most popular, most practiced and most recommended forms of physical activity. Yet little information is available concerning the influence of regular swimming on coronary heart disease (CHD). Exercise recommendations involving swimming have been generated primarily from unjustified extrapolation of the data from other modes of exercise (e.g. walking and cycling). Available evidence indicates that, similarly to other physically active adults, the CHD risk profile is more favourable in swimmers than in sedentary counterparts and that swim training results in the lowering of some CHD risk factors. However, the beneficial impact of regular swimming may be smaller than land-based exercises. In some cases, regular swimming does not appear to confer beneficial effects on some CHD risk factors. Moreover, swimming has not been associated with the reduced risks of developing CHD.
С другой стороны,
Incident physician-diagnosed myocardial infarction and angina, revascularization procedures (CABG, PTCA), and ischemic heart disease deaths during 7.7-year follow-up were compared to baseline usual distance run in 35,402 male runners.
RESULTS:Per km/day run, the men's risks declined 5% for fatal and nonfatal CHD (P=0.001), nonfatal CHD (P=0.0008), and revascularization procedures (P=0.002). Their risks for nonfatal myocardial infarctions and angina declined 7% (P=0.02) and 10% (P=0.003), respectively. Compared to <3km/day run (upper limit guideline level), >9km/day run produced risks 65% lower for angina (P=0.008), 29% lower for nonfatal CHD (P=0.04), and 26% lower for fatal and nonfatal CHD (P=0.06).
CONCLUSIONS:
Exceeding guideline physical activity levels produce important CHD-risk reductions.

DESIGN, SETTING, AND PARTICIPANTS:
A cohort of 44 452 US men enrolled in the Health Professionals' Follow-up Study, followed up at 2-year intervals from 1986 through January 31, 1998, to assess potential CHD risk factors, identify newly diagnosed cases of CHD, and assess levels of leisure-time physical activity.
MAIN OUTCOME MEASURE:
Incident nonfatal myocardial infarction or fatal CHD occurring during the follow-up period.
RESULTS:
During 475 755 person-years, we documented 1700 new cases of CHD. Total physical activity, running, weight training, and rowing were each inversely associated with risk of CHD. Men who ran for an hour or more per week had a 42% risk reduction (RR, 0.58; 95% CI, 0.44-0.77) compared with men who did not run (P<.001 for trend). Men who trained with weights for 30 minutes or more per week had a 23% risk reduction (RR, 0.77; 95% CI, 0.61-0.98) compared with men who did not train with weights (P =.03 for trend). Rowing for 1 hour or more per week was associated with an 18% risk reduction (RR, 0.82; 05% CI, 0.68-0.99). Average exercise intensity was associated with reduced CHD risk independent of the total volume of physical activity. A half-hour per day or more of brisk walking was associated with an 18% risk reduction (RR, 0.82; 95% CI, 0.67-1.00). Walking pace was associated with reduced CHD risk independent of the number of walking hours.
