“…The majority of the studies examining the combined effects of cold and exercise on cardiovascular responses among persons with cardiovascular diseases have studied CAD [18,81,89,90,[94][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109][110][111][112] and only a few heart failure [109,110]. To the best of my knowledge, none have included subjects with hypertension ( Table 2).…”

“…To the best of my knowledge, none have included subjects with hypertension ( Table 2). In contrast to studies conducted at rest, exercise-related research have either employed whole-body exposure to cold air [18,81,94,99,103,104,106,107,109,111,112] or water [108], cold air blown on face and upper chest [96,98], or while inhaled [89,95,97,103,112]. Only a few studies have included the cold pressor test stimulus performed in conjunction [100] or separately from exercise [90,101,102].…”

“…Hence, the duration of exercise (and cold exposure itself) was often relatively short, on average 10-12 min. Only a few studies included submaximal exercise [18,[107][108][109]. With the exception of one study [102], all others examined dynamic exercise (Table 2).…”

“…In the majority of the studies cardiovascular responses to varying cold exposures (cold, exercise, medication) were compared within the studied patient group. Only a few studies included healthy controls [18,90,107]. A portion of CAD patients report being cold susceptible and cardiovascular responses were compared between these groups [96].…”

“…The higher cardiovascular strain while exercising in the cold may contribute to the adverse health events among those with cardiovascular diseases [13,14]. For example, sudden or intense exercise, such as snow shoveling [15][16][17][18] or winter sports [19] increase the risk of AMI's. Previous controlled research examining the acute effects of cold alone, and in combination with exercise, among persons with cardiovascular diseases are scant.…”

Both acute and prolonged cold exposure affect cardiovascular responses, which may be modified by an underlying cardiovascular disease. In addition, exercise in a cold environment increases cardiovascular strain further, but its effects among persons with cardiovascular diseases are not well known. Controlled studies employing whole-body or local cold exposure demonstrate comparable or augmented increase in cardiac workload, but aggravated cutaneous vasoconstriction in persons with mild hypertension. A strong sympathetic stimulation of a cold pressor test, increases cardiac workload in persons with coronary artery disease (CAD), but does not markedly differ from those with less severe disease or healthy. However, cold exposure reduces myocardial oxygen supply in CAD, which may lead to ischemia. Exercise in cold often augments cardiac workload in persons with CAD more than when performed in thermoneutral conditions. At the same time, reduced myocardial perfusion may lead to earlier ischemia, angina and impaired performance. Also having a heart failure deteriorates submaximal and maximal performance in the cold. Antianginal medication is beneficial in the cold in lowering blood pressure, but does not affect the magnitude of coldrelated cardiovascular responses in hypertension. Similarly, the use of blood pressure lowering medication improves exercise performance in cold both among persons with CAD and heart failure. Both the acute and seasonal effects of cold and added with exercise may contribute to the higher morbidity and mortality of those with cardiovascular diseases. Yet, more controlled studies for understanding the pathophysiological mechanisms behind the adverse cold-related health effects are warranted.

The primary purpose of the present study was to determine oxygen uptake (VO2) and heart rate (HR) responses of patients with coronary artery disease (CAD) to common lawn-care activities. The study was conducted in three phases. In phase I, 8 men with CAD performed 30 min of push motorized lawn mowing at a self-paced rate. In phase II, 9 men with CAD performed push (no power) mowing, trimming (power and manual), and raking for 8 min each. In phase III, age-matched men and women with and without CAD (9-11 per group) performed self-propelled motorized mowing and push motorized mowing. In phase I, VO2 averaged 17.3 (SEM 3.8) ml.kg-1.min-1 during 30 min of mowing. Relative effort was 68 (SEM 1) and 76 (SEM 4)% of treadmill maximal VO2 (VO2max) and HR, respectively. In phase II, mean VO2 ranged from 8.6 (SEM 0.4) with grass trimming to 22.2 (SEM 1.6) ml.kg-1.min-1 with push manual mowing. With self-propelled mowing at three speeds in phase III, mean VO2 of the CAD groups ranged from 9.5 (SEM 0.3) to 13.8 (SEM 1.4) ml.kg-1.min-1 and represented 37%-62% VO2max. The results indicated that lawn mowing is often performed at an exercise intensity recommended for aerobic exercise training; patients who achieve a treadmill peak capacity of 4 times resting metabolic rate (4 METs) should be able to perform self-propelled motorized lawn mowing (slow speed) and grass trimming at less than 80% peak VO2; and VO2 demands of lawn mowing can be adjusted by equipment selection and/or pace.
