“…Similarly, Hyodo et al (2016) showed a moderate correlation between higher VeT 1 and better Stroop interference scores (r ¼ -0.35, p < 0.01), and Gajewski and Falkenstein (2015) found a moderate negative correlation between the interference score and the relative and absolute maximum power (r ¼ -0.40, p ¼ 0.011). Our results are consistent with studies reporting that higher aerobic fitness is related to better EF (Chaparro et al, 2019;S. J. Colcombe et al, 2004;Dupuy et al, 2015;Prakash et al, 2011).…”

“…In a longitudinal correlational study of about 1400 participants aged 19-94 years, Wendell et al (2014) found EF to be positively associated with _ VO 2max . Similarly, other authors indicated that higher _ VO 2max is associated with better interference, greater accuracy, and greater task relevant activation of the prefrontal cortex (Brown et al, 2010;Chaparro et al, 2019;Dupuy et al, 2015;Prakash et al, 2011). Furthermore, Gajewski and Falkenstein (2015) found a moderate negative correlation between the interference score and ergometric relative and absolute maximum power.…”

The present study aimed to examine relationships between executive function (EF) and variables of aerobic fitness. Participants were 32 healthy older adults ( M age = 65.1, SD = 6.6 years). We measured the first ventilatory threshold (VeT1) and the kinetics of oxygen uptake ([Formula: see text]O2), heart rate (HR), and muscle deoxygenation [HHb] during treadmill walking of either constant, moderate intensity, or increasing intensity. We assessed EF with a computerized Stroop test and Stroop measures of correct answers, reaction time, and percent interference. We found the Stroop interference score to be negatively associated with the VeT1 ( r = –0.387, p = 0.031) and positively associated with the on-transition aerobic metabolism time constant (τ) of HR ( r = 0.519, p = 0.003), [Formula: see text]O2 ( r = 0.454; p = 0.010), and [HHb] ( r = 0.644, p = 0.001). Correct responses were negatively related with τHR ( r = –0.372, p = 0.039) and τ[Formula: see text]O2 ( r = –0.500, p = 0.004). The Stroop average reaction time, congruent reaction time and incongruent reaction time were positively related to τ[HHb] ( r = 0.507, p = 0.010; r = 0.437, p = 0.029; r = 0.558, p = 0.004, respectively). Better EF was associated with faster on-transition aerobic metabolism and higher aerobic fitness among older adults.

“…If the value of α is larger, it indicates that the ant is more inclined to choose the path searched by other ants. All ants will search and traverse all nodes according to formula (1), and there will be m circuit solutions for m ants [14,15]. e collaboration stage points mainly that ants treat the pheromone left by themselves in the search process as the basis for next round of ant searching iterative solution.…”

With the continuous development of social economy, when people are pursuing economic income, they are also gradually paying attention to their own physical health. They achieve their own physical exercise through sports such as running, fitness, and mountaineering, but these sports often require a certain venue and equipment. Therefore, in view of these sports fitness demands, the ant colony algorithm is introduced to sort out the fitness activities in the context of urban residents’ supply and demand relationships, analyze the demand from both subjective and objective aspects, and explore the lack of supply of sports facilities in this paper. Analysis is conducted from cognitive and national fitness, social needs, habits, and other perspectives. It tries to guide the rational allocation and creation of resources, obtain residents’ fitness awareness and support, and provide corresponding suggestions and support for residents’ fitness activities. The simulation experimental results show that the ant colony algorithm is effective and can support the predictive analysis of the urban national fitness demand.

“…The Modified Stroop Color Word Test (MSCWT) can successfully encompass a wide array of executive function processes such as inhibition, set switching, flexibility, and working memory [ 23 ]. Chaparro et al [ 24 ] has shown the effect of MSCWT on cognitive performance in older adults while standing or walking and found lower cognitive performance as evaluated by higher Stroop interference, particularly during the switching block. Furthermore, increased age and decreased aerobic capacity have been associated with decreased cognitive performance during the switching block while walking [ 24 ].…”

Hypertension is considered a risk factor for cardiovascular health and non-amnestic cognitive impairment in older adults. While heart rate reserve (HRR) has been shown to be a risk factor for hypertension, how impaired HRR in older adults can lead to cognitive impairment is still unclear. The objective of this study was to examine the effects of HRR on prefrontal cortical (PFC) activation under varying dual-task demands in older adults. Twenty-eight older adults (50–82 years of age) were included in this study and divided into higher (n = 14) and lower (n = 14) HRR groups. Participants engaged in the cognitive task which was the Modified Stroop Color Word Test (MSCWT) on a self-paced treadmill while walking. Participants with higher HRR demonstrated increased PFC activation in comparison to lower HRR, even after controlling for covariates in analysis. Furthermore, as cognitive task difficulty increased (from neutral to congruent to incongruent to switching), PFC activation increased. In addition, there was a significant interaction between tasks and HRR group, with older adults with higher HRR demonstrating increases in PFC activation, faster gait speed, and increased accuracy, relative to those with lower HRR, when going from neutral to switching tasks. These results provide evidence of a relationship between HRR and prefrontal cortical activation and cognitive and physical performance, suggesting that HRR may serve as a biomarker for cognitive health of an older adult with or without cardiovascular risk.
