Background: This study aimed to evaluate the relationship between physical activity habits, physical performance and cognitive capacity in older adults' population of Italy and Slovenia.
Methods: Anthropometric characteristics and body composition bioelectrical impedance analysis were evaluated in 892 older adults (60-80 y). Aerobic capacity was measured using the 2-km walk test and handgrip and flexibility tests were performed. Physical activity habits and cognitive functions were evaluated by the Global-Physical-Activity-Questionnaires (GPAQ) and by Montreal-Cognitive-Assessment (MoCA) questionnaires, respectively.
Results: GPAQ scores were associated with lower BMI (r=-0.096; P=0.005), lower percentage of fat-mass (r=-0.138; P=0.001), better results in the 2-km walk test (r=-0.175; P=0.001) and a higher percentage of fat-free mass (r=0.138; P=0.001). We also evaluated that a higher MoCA Score correlates with age (r=-0.208; P=0.001), 2-km walk test (r=-0.166; P=0.001), waist-hip ratio (r=-0.200; P=0.001), resting heart-rate (r=-0.087; P=0.025) and heart-rate at the end of 2-km walk test (r=0.189; P=0.001).
Conclusions: Older adults with a higher level of daily physical activity showed reduction in fat-mass and BMI, and higher aerobic fitness; these characteristics have a protection effect on cognitive function.

People with peripheral arterial disease (PAD) and intermittent claudication (IC) experience impaired walking due to an imbalance between muscle oxygen supply and demand during exercise. Studies with near-infrared spectroscopy (NIRS) during treadmill tests reveal notable tissue deoxygenation with slow recovery. This cross-sectional study aimed to compare behavior of calf muscle oxygenation during the incremental shuttle walking test (ISWT) with a continuous treadmill test (3.

Background: Blood flow restriction caused by peripheral arterial disease (PAD) is reflected in reduced walking capacity. The peripheral mechanisms that may affect the walking capacity of individuals with PAD are not yet fully understood. This study aimed to 1) compare tissue oxygenation and muscle metabolism of individuals with PAD with different walking capacities and 2) evaluate which variables have the greatest potential to explain the variability in distance walked between performance levels.

Background: Cardiorespiratory fitness is linked to various health outcomes. This study aimed to establish cut-off values for estimated cardiorespiratory fitness associated with poor physical functioning in middle-aged to older adults.
Methods: A total of 2638 participants (1083 males), aged 40-69 years, performed a 6-min walking test (6MWT) to estimate cardiorespiratory fitness (VO
Walking training decreases cardiovascular load after walking to maximal intermittent claudication in patients with peripheral artery disease.

Purpose: This study investigated whether: 1) walking training (WT) changes cardiovascular load after walking until maximal intermittent claudication (IC) in patients with peripheral artery disease (PAD); and 2) acute and chronic cardiovascular responses to walking were related to each other.
Methods: A randomized, controlled, parallel-group design was employed. Thirty-two men with PAD and IC were randomly assigned to one of two groups: WT (n=16) or control (CO, n=16) twice a week for 12 weeks.

The aim of the study is to investigate the association of cardiorespiratory fitness (CRF) and muscular strength indicators with gray matter volume (GMV) and to study whether fitness-related regions of GMV are associated to executive function (EF) in cognitively normal older adults. Ninety-one cognitively normal older adults (71.69 ± 3.
