“…snow) will increase the requirements [45,46]. Although walking efficiency on easy paths does not markedly differ between individuals, this difference may increase on more difficult paths and depends on mountaineering experience [47,48]. Thus, in those with less experience of mountain walking, performance requirements may increase further.…”

Life expectancy has markedly increased during recent decades, resulting in a growing number of older individuals. Many of these elderly are turning to mountain sports activities in search of fun and new challenges. Although the scientific community has taken broad interest in the ageing process and how it affects physical and mental performance, little attention has focused on the elderly mountaineer. Mountain sports demand a relatively high degree of physical fitness and, because fitness and health decline with age, the risk of injury and death during mountain sports will increase. However, little information is available on fitness requirements for elderly mountaineers. This article mainly focuses on such requirements, and on performance limitations, assessment of individual performance, and training recommendations. A normal ascent rate of 300 meters per hour (up to 3500 m) requires an altitude-dependent relative oxygen consumption of 18-22 ml x min(-1) x kg(-1) or an ergometric performance of 1.2-1.5 watt x kg(-1) below the individual anaerobic threshold. Mild cardiopulmonary and musculoskeletal diseases are not contraindications for mountain sports activities, provided the proposed fitness requirements are attained. A regular exercise-training program under medical and sports expert advice will help the elderly to achieve these fitness standards, enjoy the mountain environment, and prevent injuries and fatalities.

“…Nearly all trials of training for coronary patients have indeed shown a great reduction in angina frequency and an increase in angina threshold. 62 63 Exercise training has been found to be as eVective for angina as blockade 22 and also to reduce the total ischaemic burden. 64 ENHANCED CORONARY BLOOD FLOW This eVect, discussed above (myocardial blood supply), may reduce angina, lessen the size of future infarction, and play some part in the mortality reduction which follows exercise based cardiac rehabilitation (see below).…”

“…Interventions that improve physical performance in patients with angina by reducing myocardial oxygen requirements have been shown not to be associated with changes in maximum tolerated MVO 2 . However, myocardial mechanical stress at any given level of external workload decreases with training and, therefore, achievement of angina-limiting MVO 2 is delayed, which allows workloads of higher intensity and duration [35][36][37] .…”

Objective:The myocardial efficiency index (MEI) correlates the myocardial oxygen consumption (MVO 2 ) with the maximum oxygen consumption (VO 2 max), this index provides information about the cardiovascular efficiency (CVEf). In athletes, the MEI improves after a microcycle training, however in patients with cardiovascular disease undergoing cardiac rehabilitation program (CRP), IEM behavior could be a good estimator related to the improvement training period. The objective of this study was to determine the myocardial efficiency index behavior in patients with heart disease and high cardiovascular risk (HCVR) after a CRP. Methods: An ambilective, descriptive, analytical, non-randomized cohort study was conducted. Patients with heart disease of mixed etiology and HCVR admitted to a CRP for 4-6 weeks were selected. All patients performed a maximal exercise test in band before and after the CPR. Thresholds of VO 2 peak, METs-load, double product (DP), and MEI were determined. A cutoff point for the MEI was established using a ROC curve with a value of 7.37, area under the curve: 0.68 (95% CI = 0.61-0.76, p < 0.001), sensitivity 0.60, and 1-specificity 0.35. Results: A total of 193 patients with a mean age of 62.3 years were included, predominantly men (66.2%). Percentages changes in the MEI: −27.1% (p < 0.001), METs: −43.1% (p < 0.001), DP: 5.7% (p < 0.01), and MVO2: 8.3% (p < 0.01) were observed at the end of CRP. Conclusions: Significant change in the MEI was observed after CRP associated to CVEf improvement, suggesting that this parameter could be considered as a good clinical tool in the CRP care programs.
