Background Hiking is one of the most popular activities among the elderly in Alpine regions. Due to the long-lasting, moderately intensive nature of this form of physical activity, hiking is generally considered to be beneficial to health. However, it is currently unclear whether once-weekly hiking鈥攁s commonly practiced at weekends鈥攔eally does yield such positive effects in elderly persons aged 60聽years and over. Objectives This study investigated the effect of a single weekly mountain hiking session on cardiovascular risk factors. Materials and methods A 9-month mountain hiking program was completed by 14聽male (age 65.6鈥壜扁€?.7聽years) and 10聽female (age 66.2鈥壜扁€?.4聽years) elderly participants. The program consisted of a single weekly hiking session with the goal of achieving a 500-m altitude increase within 3聽h. Before and after the 9-month program, an electrocardiogram (ECG) was performed and blood pressure, glycated hemoglobin (HbA1c), high-density (HDL) and low-density lipoprotein (LDL) measurements were made. Results The elderly participants showed a normal cardiovascular risk profile at the start of the investigation. The estimated net energy expenditure for one hiking session was approximately 521鈥壜扁€?1聽kcal. Over the 9-month period, no changes were found in any of the investigated parameters for the entire group. However, participants with untreated hypertension showed a reduced systolic blood pressure. Conclusion The present investigation showed that moderate-intensity activity only at weekends does not improve cardiovascular risk factors in elderly persons with a relatively normal cardiovascular risk profile. Conversely, elderly persons suffering from hypertension might profit from such a practice.
