In exercise and cognition research, few studies have investigated whether and how the qualitative aspects of physical exercise may impact cognitive performance in the short or long term. This commentary, after recalling the evidence on the “dose-response” relationship, shifts the focus to intersections between different research areas that are proposed to shed light on how qualitative exercise characteristics can be used to obtain cognitive benefits. As concerns the acute exercise area, this commentary highlights the applied relevance of developmental and aging studies investigating the effects of exercise bouts differing in movement task complexity and cognitive demands. As regards the chronic exercise area, potential links to research on cognitive expertise in sport, functional ability in aging, and life skills training during development are discussed. “Gross-motor cognitive training” is proposed as a key concept with relevant implications for intervention strategies in childhood and older adulthood.

The purpose of this study was to assess the effects of exercise intensity, age, and fitness levels on executive and nonexecutive cognitive tasks during exercise. Participants completed a computerized modified-Stroop task (including denomination, inhibition, and switching conditions) while pedaling on a cycle ergometer at 40%, 60%, and 80% of peak power output (PPO). We showed that a bout of moderate-intensity (60% PPO) to high-intensity (80% PPO) exercise was associated with deleterious performance in the executive component of the computerized modified-Stroop task (i.e., switching condition), especially in lower-fit individuals (p < .01). Age did not have an effect on the relationship between acute cardiovascular exercise and cognition. Acute exercise can momentarily impair executive control equivalently in younger and older adults, but individual’s fitness level moderates this relation.

Calpains and calpastatin can degrade muscle proteins, but no research has investigated the expression pattern of calpains and calpastatin after exhaustive exercise.
To investigate the alterations in expression of μ-, m-, and n-calpain and calpastatin after exhaustive exercise and its association with muscle injury.
64 rats divided into 2 groups, a nonexercise control group and an acute-exhaustive-exercise (AEE) group. Biopsies in the AEE group were taken at different times after exercise.
Calpastatin protein expression and m-calpain activity increased early after exercise, but both n-calpain protein expression and μ-calpain activity generally decreased with time. n-Calpain mRNA expression was down- regulated from late after exercise.
The increased m-calpain activity might promote muscle-protein degradation and muscle injury. On the contrary, calpastatin might execute a protective function against muscle injury. The change in p-calpain activity was found earlier than muscle injury and therefore might serve as a useful predictor of muscle injury.

A recent study indicated that acute aerobic exercise improves cognitive flexibility in adults. The current study assessed age, habitual physical activity, and physical fitness as moderators of this improvement and examined whether the gains still exist an hour after the exercise session. The alternative-uses test, assessing cognitive flexibility, was administered individually to 20 older (age 63.67 ± 3.55 yr) and 19 young (age 23.9 ± 1.22) women before, immediately after, and an hour after a single moderate aerobic-exercise session. Results indicated significant improvement in cognitive flexibility in the older group immediately after the exercise but a decrease at the 1-hr follow-up. Further analysis indicated that physical fitness accounted for this improvement (R = –.622, p < .01). No such differences were observed in the young group. Further studies are needed to examine the duration of this effect, as well as the role of physical fitness as a moderator of it.

Physical activity is associated with an antidepressant effect in clinical depression. Self-efficacy is one mechanism proposed to explain this effect. In this study we compared the changes in mood following exercise sessions with high and stable self-efficacy (stationary bike exercise) to exercise sessions with initially low but increasing self-efficacy (martial arts). The experimental design incorporated repeated measures and counter-balancing. Twelve clinically depressed participants completed 45-min exercise sessions consisting of stationary bike use and martial arts. A waiting control condition of 30 minutes was conducted before each exercise session. During martial arts, statistically significant increases in positive affect, reductions in negative affect and state anxiety, and increased self-efficacy were observed. During the stationary bike exercise no statistically significant changes were found. The results indicate that an increase in self-efficacy may be important for mood benefits to occur.

Racial differences in psychological determinants of exercise exist between non-Hispanic blacks (blacks) and non-Hispanic whites (whites). To date, no study has examined racial differences in the psychological responses during and after exercise. The objective of this study was to compare psychological outcomes of single exercise bouts in blacks and whites.
On 3 separate occasions, sedentary black (n = 16) and white (n = 14) participants walked on a treadmill at 75%max HR for 75 minutes. Questionnaires assessing mood, state anxiety, and exercise task self-efficacy were administered before and after each exercise bout. In-task mood and rating of perceived exertion (RPE) were measured every 5 minutes during exercise.
Exercise self-efficacy and psychological distress significantly improved in both blacks and whites. However during exercise blacks reported more positive in-task mood and lower RPE compared with whites.
These data suggest that racial differences exist in psychological responses during exercise. Further research should confirm these findings in a larger, free-living population.

This study aimed to determine how cognitive control, engaged in a task requiring selective inhibition, is affected by acute steady-state exercise. An adapted version of the Eriksen flanker task, involving three types of trials that varied according to their level of congruency (congruent trials, stimulus-incongruent trials, and response-incongruent trials) was performed during 2 periods of 20-min cycling at a carefully controlled intensity (50% of maximal aerobic power). The results indicated that moderate exercise improves reaction time (RT) performance on the Eriksen flanker task. This facilitating effect appeared to be neither dependent on the nature of the interference (stimulus level conflict vs. response level conflict) nor on the amount of cognitive control engaged in the task (congruent vs. incongruent trials). Distributional RT analyses did not highlight any sign of impairment in the efficiency of cognitive control.

Self-efficacy can be affected by mastery experiences and somatic sensations. A novel exercise experience and associated sensations may impact self-efficacy and subsequent behaviors. We investigated the effect of a single exercise session on self-efficacy for sedentary endometrial cancer survivors compared with sedentary women of a similar age, but with no cancer history.
Twenty survivors and 19 controls completed an exercise session performed as a submaximal cycle ergometry test. Sensations and efficacy were measured before and after exercise. Repeated measures analysis of variance (ANOVA) was performed. Regression models were used to determine predictors of self-efficacy and subsequent exercise.
Self-efficacy increased for both survivors and controls, but survivors had a higher rate of increase, and the change predicted subsequent exercise. The association between exercise-related somatic sensations and self-efficacy differed between the 2 groups.
A novel exercise experience had a larger effect on self-efficacy and subsequent exercise activity for endometrial cancer survivors than controls. Somatic sensations experienced during exercise may differ for survivors, which may be related to the experience of having cancer. Understanding factors affecting confidence in novel exercise experiences for populations with specific cancer histories is of the utmost importance in the adoption of exercise behaviors.
