"You Kick Like A Girl!" The Effects of Gender Stereotypes on Motor Skill Learning in Young Adolescents.

This study investigated the effect of gender stereotypes on (a) a soccer learning task based on accuracy (i.e., shooting on different size targets) among young adolescents and (b) the strategy used to score as many points as possible. After performing 10 baseline trials, 45 young adolescents were randomly divided into three groups: positive stereotype, negative stereotype, and control. Then, they performed five blocks of 10 trials and two retention tests, 1 and 3 days after the stereotype manipulation to assess the relatively permanent consequences of stereotype effects. Results showed that when the negative stereotype was induced, participants performed worse during the acquisition phase and the first retention test. The positive stereotype only had a positive effect on performance during the second retention test. These findings provide the first evidence of the effect of gender stereotypes on motor learning tasks requiring accuracy among young adolescents.

"Men are Better Than Women!" The Positive Effect of a Negative Stereotype Toward Women on a Self-Paced Cycling Exercise.

Previous research on the stereotype threat phenomenon has shown that inducing a negative stereotype toward a group debilitates motor performance despite the increase in motivation. Most of the studies focused on tasks requiring technical skills. However, what happens when the task does not require technical skills but focuses on energy expenditure? To examine this question, 34 male and female participants were assigned to a negative stereotype toward women and a nullified-stereotype condition and performed 20 min of self-paced cycling exercise. The authors hypothesized better performances when participants were assigned to the negative stereotype toward women condition than when assigned to the nullified-stereotype condition. As predicted, men and women increased their performances, accompanied by increases in heart rate. Concerning women, this result provides support for the notion that the effect of inducing a negative stereotype is task dependent, but further research is needed to more deeply investigate the mechanisms involved.

Exergaming in augmented reality is tailor-made for aerobic training and enjoyment among healthy young adults.

In recent years, the use of exergaming for physical activity practice has gain in popularity but few is known about the use of augmented reality for physical activity, particularly at moderate to vigorous intensities. The present study examined the use of an exergame in augmented reality for aerobic training in healthy young adults. In a within-subject design, 18 participants (19.8 ± 1.4 years of age) have performed two physical activity sessions playing dodgeball. Indeed, they realized a classical dodgeball session and an exergaming session with an augmented reality version of dodgeball game. Physical loads and intensities were measured with accelerometers, RPE and heart sensors. Enjoyment experienced during the sessions was measured with the short version of the physical activity enjoyment scale questionnaire. Results revealed that both physical load and intensity were appropriate for aerobic training in the two conditions (i.e., classical and exergame in augmented reality) although values were significantly higher in the classical condition. Enjoyment was high in the two conditions with a higher significant value in the classical condition compared to the exergame in augmented reality condition. Put together, these results indicate that an aerobic state can be attained through both physical gameplay and its augmented reality equivalent and was associated to a high level of enjoyment among healthy young adults.

Cognitive dual-task does not annihilate the negative effects of gender stereotype threat on girls' motor learning.

Stereotype threat, a key concept in social psychology, occurs when individuals fear they may confirm negative stereotypes about their social group (Steele, 1997). This phenomenon can significantly impair motor learning, particularly in children. Given the robust nature of stereotype threat, research it is now focused on mitigating these negative effects. According to the explicit monitoring hypothesis, it is suggested that distracting individual's attention can lead to an annihilation of stereotype threat effects, however, to date, this hypothesis has not been examined in children. The present study examined the effect of stereotype threat in a dual task condition on children's motor learning. One hundred and fifty girls (mean age = 10.96 ± .80 years) were randomly assigned into 3 groups; 1- explicit gender stereotype threat; 2- explicit gender stereotype threat + dual task; 3- control. The task consisted of a soccer-kicking task in which the participants had to score the most points by kicking the soccer ball towards the goals on the wall. This study included three phases; 1- pretest (10 trials); 2- practice phase (5 blocks of 10 trials); 3- retention test (10 trials). During the practice phase, the results indicated that participants in the control condition performed better (M = 1.46, SD = .19) than participants in the gender stereotype threat condition (M = 1.25, SD = .16, p < .001), and, than participants in the gender stereotype threat + dual task paradigm condition (M = .92, SD = .19, p < .001). However, participants in the gender stereotypes + dual task paradigm condition performed worse than participants in the gender stereotype threat condition (p < .001). In addition, the results of the retention test showed that participants in the control condition performed better (M = 1.51, SD = .34) than participants in the gender stereotype threat condition (M = 1.24, SD = .35, p = .001), and participants in the gender stereotype threat + dual task paradigm condition (M = 1.15, SD = .49, p < .001). In conclusion, these results do not support the potential neutralizing effect of a cognitive dual task in a stereotype threat condition in children.

Do negative stereotypes and domain identification moderate novice participants' performance on a soccer-dribbling task ?

The present research aimed to explore whether negative stereotypes and domain identification moderate novice participants' performance on a soccer-dribbling task, using a novel statistical procedure to explore within-subjects moderation effects. Fifty-four women with no soccer experience (Mage = 19.92, SDage = 1.0) were recruited and assigned to a negative stereotype condition or a nullified-stereotype condition and performed a soccer-dribbling task as fast as possible. Using moderation analyses for repeated measures, results showed (i) that inducing a negative stereotype did not moderate participants' performance, and (ii) that domain identification did not moderate participants' performance in a stereotype threat situation. In conclusion, the novice participants performance did not depend on the value of domain identification and the stereotype condition. More research is nonetheless needed to disentangle the question of how and why novice participants can be impacted by a stereotype threat situation.

Gender stereotypes and motor performance: How explicit and implicit stereotypes influence girls standing long jump and anxiety.

OBJECTIVES: Inducing a negative stereotype toward women usually leads to a decrease in women's motor performance. Given that most studies have focused on explicit stereotype induction among adults, the main aim of this study was to investigate the effects of explicit and implicit gender stereotypes on standing long jump performance in children. The second aim was to investigate the effects of these same manipulations on children's state anxiety. DESIGN: A mixed model design with within-between-subject was used with standing long jump performance and state anxiety as dependent variables. METHOD: Two hundred and four children (Mage = 10.95 years, SDage = 0.85) participated in this study and were randomly assigned, after baseline measurement, into four different groups (i.e., explicit/implicit vs. explicit vs. implicit vs. control). Specifically, participants performed 8 trials of standing long jump (4 trials during the baseline phase and 4 trials during the experimental phase). Children also completed the competitive state Anxiety Inventory at baseline as well as immediately after the trials. RESULTS: For motor performance, children in the explicit/implicit group and in the implicit group were negatively affected by the stereotype manipulation during all trials whereas participants in the explicit group were only negatively impacted during the last two trials. However, regarding state anxiety, children were negatively affected after both explicit only and implicit only manipulations and more significantly after explicit/implicit manipulation. CONCLUSIONS: The present research showed that the explicit and implicit manipulations influenced motor performance differently, but that these two manipulations increased state anxiety in the same way. Moreover, the combination of the explicit and implicit inductions leads to a greater significant negative influence on state anxiety but not motor performance.

Effect of a sex stereotype on cortical activity during a self-paced exercise: A motor-related cortical potential approach.

Recent research has shown that inducing a negative stereotype toward women does not always decrease the subsequent motor performance of women, but can increase it, especially during endurance tasks. The mechanisms involved are nonetheless still poorly understood. The main aim of the present study was to investigate the effect of a negative stereotype toward women on men's and women's performance during an endurance task, and to analyze the neuropsychological mechanisms involved through motor-related cortical potentials and motivation toward men/women. Thirty-four participants were assigned to a negative stereotype toward women condition and a nullified-stereotype condition and performed 80 self-paced intermittent isometric elbow contractions at a moderate perceived intensity. Results showed that women performed better when assigned to the negative stereotype toward women condition, they were more motivated to outperform men, and their MRCP amplitudes were higher in this same condition over the prefrontal cortex (i.e., FP1 and FP2). Concerning men, they also performed better when the negative stereotype toward women was induced. However, no effect emerged on motivation toward women and MRCP amplitudes. This study showed that inducing a negative stereotype during an endurance task led to a performance increase in women, which is contrary to the stereotype threat theory, strengthening the idea of a task-dependency effect when inducing a negative stereotype. This performance improvement observed in women may be caused by increased motivation to outperform men and a planning of the upcoming movement. Concerning men, more research is needed to clarify the mechanisms involved in such performance improvement.

Exploring the Health Effectiveness of a Physical Activity Program Co-Constructed with Students after the COVID-19 Pandemic.

BACKGROUND: University students have low levels of physical activity and high levels of sedentary behaviors that were exacerbated by the COVID-19 pandemic. Even before the pandemic, there was poor uptake of university sports activities. Therefore, it is essential to develop and test innovative programs to increase students' motivation to engage in physical activity in order to prevent any future deterioration in their general health. OBJECTIVE: This exploratory study was conducted to test the effectiveness of a physical activity program that was co-constructed with students. METHODS: First, a workshop drawing on social design methodologies and the fundamentals of physical activity programs was conducted to assess students' needs and desires in terms of physical activity. Second, the effectiveness of a program co-constructed with students on the basis of this workshop was assessed on physical and mental health parameters. The results showed that the workshop outcomes allowed the physical activity program to be tailored to meet students' expectations (e.g., session duration and type of activities). This innovative physical activity program was found to improve body image, autonomous motivation, and certain physical parameters. At the end of the 8-week program, the adherence rate was 89%, and 83% of the final respondents expressed a wish to re-enroll for the following semester. CONCLUSIONS: Involving students and considering their wishes, needs, and objectives could facilitate the development of attractive and innovative programs.

Influence of negative stereotype on physical activity level among older adults during a training session.

The present research examined the effect of a negative stereotype induction on older adults' physical activity level, measured objectively and subjectively. Twenty older adults (18 women and two men; Mage = 67.4, SDage = 4.4) were assigned to a control condition, a neutral condition and a negative stereotype condition during three separate visits (i.e., within-subject design). In each physical activity session, participants performed the same training. Objective physical activity level was the time spent at moderate to vigorous intensity measured by accelerometry and subjective physical activity level was measured with the RPE-session method. Inactivity time was also objectively assessed. Results revealed no effect of the different conditions on objective physical activity level, but subjective physical activity level and inactivity time were lower in the neutral condition and in the negative stereotype condition compared to the control condition. It was suggested that when a negative stereotype is induced, participants perceived the task as less intense compared to the control condition, which result in less inactivity time, suggesting that the negative stereotype had a positive influence on physical activity. Another interesting result was that effects were similar in the negative stereotype condition and in the neutral condition, revealing that the neutral condition might not be a control condition. While these results are not in line with the stereotype threat literature, they echo previous recent studies also showing a positive effect of a negative stereotype induction, calling into question the stereotype threat theory.

Does the Effect of Stereotypes in Older People Depend Upon Task Intensity?

This study examined the effect of negative and positive stereotypes on the strength produced by older adults at different perceived effort intensities, reflecting different levels of task difficulty. Fifty older women were randomly assigned to a positive stereotype, a negative stereotype, or a control condition. Before (T1) and after (T2) the stereotype manipulation, they were asked to perform a voluntary isometric contraction at a level of muscular effort that corresponded to four perceived effort intensities ("easy," "moderate," hard" and "very hard"). Results showed that participants attained greater strength during the easy and hard tasks after exposure to both positive and negative stereotypes. At the moderate and very hard intensities, stereotype induction did not significantly change the strength from the baseline performance. While these results are not fully in line with the stereotype threat theory, they provide evidence that task difficulty could modulate the effect of aging stereotypes during physical tasks.

Can an Eight-Session Multicomponent Physical Exercise Program Reduce Fall Risk and Fear of Falling among the Elderly?

In older populations, falls are responsible for decrease autonomy and increased pain and injuries. With aging, fall risk is multifactorial and associated with sarcopenia, impaired balance, falls themselves and psychological factors such as fear of falling. The objectives of the present study were: (a) to test the effects of a short multicomponent physical exercise program on fall risk and fear of falling; and (b) to analyze the relationship between fall risk and fear of falling. The participants were thirty-five older persons who were engaged in an eight-session physical exercise program. Balance (i.e., One-leg Balance Test, and Functional Reach Test), lower-limb endurance (i.e., Wall-sit Test) and fear of falling were measured before and after the multicomponent physical exercise program. Results indicated an increase in balance and a diminution of fear of falling after the end of the physical exercise program (p < 0.05). The program has an effect on lower limb endurance (p > 0.05). Gains in balance were correlated to the diminution of fear of falling (p < 0.05). An 8-week multicomponent physical exercise program based on balance is efficient to reduce fall risk and fear of falling among the elderly.

Self-efficacy and stereotype threat effects on handgrip strength performance in less active people living with HIV.

People living with HIV (PLHIV) are not physically active enough. As nonexercisers are perceived as less healthy, less active and less strong, it is likely that PLHIV would be subject to a nonexerciser stereotype threat. We looked to elucidate the effect of the emerging nonexerciser stereotype on handgrip strength performance among less active PLHIV. We also sought to observe the modulating role of self-efficacy in the relationship between stereotype activation and performance.Eighteen PLHIV were recruited to participate in two experimental sessions in which both a stereotypical context and self-efficacy were manipulated. Participants performed a handgrip task comprising a 15-s fatiguing maximal voluntary isometric contraction (MVC) exercise preceded (Pre) and followed (Post) by 5-s MVCs. In each session, (i.e. high and low self-efficacy), four experimental conditions (i.e. Control 1; Control 2; Stereotypical; Self-Efficacy) were performed.A significant performance decrease of the 15-s fatiguing MVC exercise was systematically observed when the nonexerciser stereotype was induced (0.01 < p < 0.001). In addition, this performance re-increased after a high self-efficacy manipulation (p < 0.001). Pre- and post- 5-s MVCs were also significantly depressed after the stereotypical condition (0.01 < p < 0.001) and improved following high self-efficacy manipulation (p < 0.001).Our results revealed a detrimental stereotype threat effect on performance during a handgrip task when the nonexerciser stereotype was activated. A high self-efficacy feedback increased performances significantly whereas no significant difference was observed between the stereotypical and low self-efficacy conditions. These results indicate that self-efficacy can modulate the deteriorating effect of a negative exercise stereotype on task performance in less active PLHIV.Highlights Handgrip strength was decreased and performance fatigability increased when a negative exercise stereotype was induced.Performance fatigability and handgrip strength were restored after positive performance feedback was given.Positive task performance feedback could temper the detrimental effects of a negative stereotypical context among less active people living with HIV.

Five-factor model personality traits and grip strength: Meta-analysis of seven studies.

OBJECTIVE: To examine the association between Five-Factor Model personality traits and grip strength. METHOD: Adults aged 16 to 104 years old (N > 40,000) were from the Health and Retirement Study, the Midlife in the United States Study, The English Longitudinal Study of Aging, the National Health and Aging Trends Survey, the United Kingdom Household Longitudinal Study, and the Wisconsin Longitudinal Study graduate and sibling samples. Participants had data on personality traits, demographic factors, grip strength, and mediators such as depressive symptoms, physical activity, body mass index (BMI), and c-reactive protein (CRP). RESULTS: Across all samples and a meta-analysis, higher neuroticism was related to lower grip strength (meta-analytic estimate: -0.07, 95%CI: -0.075; -0.056). Higher extraversion (0.04, 95%CI: 0.022; 0.060), openness (0.05, 95%CI: 0.032; 0.062), and conscientiousness (0.05, 95%CI: 0.04; 0.065) were associated with higher grip strength across most samples and the meta-analysis. Depressive symptoms were the most consistent mediators between neuroticism and grip strength. Depressive symptoms and physical activity partly mediated the associations with extraversion, openness, and conscientiousness. Lower CRP partly mediated the association with conscientiousness. Sex moderated the associations for extraversion, openness, and conscientiousness, with stronger associations among males. Age moderated the neuroticism association, with stronger associations among younger individuals. CONCLUSION: This study provides replicable evidence that personality is related to grip strength and identifies potential moderators and mediators of these associations. Overall, higher neuroticism is a risk factor for low grip strength, whereas high extraversion, openness, and conscientiousness may be protective.

Promoting Physical Activity Among University Students During the COVID-19 Pandemic: Protocol for a Randomized Controlled Trial.

BACKGROUND: Since the beginning of the COVID-19 pandemic, sanitary context and e-learning have greatly modified student lifestyles and led to deteriorations in their mental health. An increase in anxiety and depressive symptoms and sedentary behaviors, reduction in physical activity, and a stronger tendency to move toward unhealthy diet have been demonstrated. This finding highlights the need for innovative interventions to promote healthy lifestyle among students. OBJECTIVE: This research protocol aims to evaluate the effects of an intervention program on the lifestyle and psychological state of students. METHODS: Students from University of Nîmes were recruited and randomly assigned to 1 of 2 following conditions: an intervention group and a control group. Participants in the intervention group were engaged in an 8-week physical activity program. Prior to the start of the program, design-based innovative workshops were conducted with participants to ensure that the program was co-constructed by the users and met their specific needs. Students in the control group did not receive any intervention. For each group, measures of physical activity, sedentary time, anthropometric data, sleep, physical condition, and psychological variables (eg, anxiety, depression, motivation, body appreciation, perceived control, well-being) were conducted at baseline and 9 weeks later. RESULTS: A total of 110 participants were initially included. Reporting of the results is projected for the spring of 2022. CONCLUSIONS: It is anticipated that this innovative intervention co-constructed by pairs will promote a healthier lifestyle and psychological health in students. There is every reason to believe that a mobilized co-construction approach is a promising strategy to limit unhealthy habits and promote physical activity while increasing motivation. The development and evaluation of interventions to address the specific needs of university students is essential and could be transferred to other vulnerable populations such as people with chronic diseases or older people.

Relationship between personality and physical capacities in older adults: The mediating role of subjective age, aging attitudes and physical self-perceptions.

Walking speed and muscular strength are two main markers of health in adulthood. Previous studies have shown that personality traits may predict these two outcomes. However, little is known about the mechanisms underlying these relationships. Thus, the present study examined whether personality traits are associated with walking speed and muscular strength through the mediating role of subjective age (how young or old individuals experience themselves to be), attitudes toward aging and physical self-perceptions. Community-dwelling older women (N = 243; Mage = 73.0; SDage = 6.5) were recruited. For reasons of recruitment feasibility, participants were only older women. They were requested to complete a questionnaire measuring personality, subjective age, attitudes toward aging and physical self-perceptions. Following this, their walking speed and their muscular strength were investigated. Data were analyzed using structural equation modeling. In line with the literature, we extended the associations between extraversion, neuroticism, conscientiousness and walking speed and between conscientiousness, neuroticism, openness and muscular strength. Physical self-perceptions appear to be a robust mediator between personality traits and walking speed whereas attitudes toward aging and subjective age mediated the personality traits/muscular strength relationship. This study provides evidence, for the first time, that the associations between personality traits and physical capacities are different according to the physical capacities investigated. Based on these results, it could be interesting to adapt physical activity interventions to the psychological profile of older adults.

Effects of age, gender, frailty and falls on spatiotemporal gait parameters: a retrospective cohort study.

BACKGROUND: Many studies have explored spatial and temporal gait parameters in the elderly, and showed that frailty status, fall history, age, and gender may individually strongly influence these parameters. However, it appears necessary to investigate the confounding factors more deeply in order to better know the specific role of each of these factors impacting the evolution of gait with the increase of age. AIM: The aim of the present study was to determine the influence of frailty status, fall history, age and gender on spatiotemporal gait parameters. We hypothesized that frailty was the factor that most influence gait parameters. DESIGN: The present is a monocentric retrospective study. SETTING: This is a monocentric retrospective study performed at Nice University Hospital Center on older out-patients. POPULATION: Older adults were included in the study. This study explored for the first time how frailty status, age, gender and history of falls impact the multiple spatiotemporal parameters of gait using linear mixed models (LMM). RESULTS: 479 older adults (360 women and 119 men; 213 non-frail, 228 prefrail and 38 frail; aged from 65 to 94 years; 403 non-fallers and 73 fallers). Frailty status explained fully: 1) the gait speed; 2) the cadence; 3) the initial double contact (DS1); 4) the percentage of the single support phase; 5) the final double contact (DS2); and VI) the percentage of the swing phase of the gait cycle. CONCLUSIONS: The results of this study allowed a deeper understanding of the confounding factors since LMM highlighted the importance of frailty status for explaining all the spatiotemporal gait parameters. CLINICAL REHABILITATION IMPACT: These results showed that clinical intervention should focus on reducing frailty status to improve gait. It is also interesting to note that a history of falls explains none of the spatiotemporal gait parameters which suggests that it may be possible to improve gait in all frail subjects irrespective of their history of falls.

Can the Stereotype Threat and Lift Phenomenon Be Applicable to a Muscular Endurance Task?

Purpose. Inducing a negative stereotype toward women usually leads to a decrease in women performance and an increase in men performance. These effects were observed during technical tasks. The purpose of the present study was to investigate the effect of this sex stereotype during a non-technical muscular endurance task. The perception of effort, closely related to endurance performance, was also recorded. Based on the type of task and the mere effort account, we predicted that both men and women in the negative stereotype toward women condition would perform better than participants in the two other groups. Method. Seventy-seven participants (38 women and 39 men) were randomly assigned to a negative stereotype toward women, a nullified-stereotype, or a control condition. Then, they performed a submaximal handgrip task until exhaustion at 50% of their maximal strength. Results. This study showed that performance at T2 was reduced for men and women in the nullified-stereotype and control conditions, but not in the negative stereotype toward women condition, revealing that participants in the negative stereotype toward women condition performed better than participants in the other conditions. No significant difference was observed concerning the perception of effort according to the conditions. Conclusion. As compared to technical tasks, inducing a negative stereotype toward women increased women's performance. The perception of effort could be responsible for this performance improvement. However, more research is needed to investigate the mechanisms involved. Concerning men, in line with the stereotype lift phenomenon, a performance increase was observed in this same condition.
