Exercise, changes in aerobic capacity, and changes in self-perceptions: An experimental investigation

Subjects in an exercise training condition participated in a 10-week aerobic exercise class, whereas subjects in waiting-list control and independent control conditions did not. The results indicated that subjects in the training condition evidenced reliably greater improvements in physical fitness (aerobic capacity) and reported reliably greater improvements in their abilities and confidence in both the physical area (e.g., ability to run distances) and nonphysical area (e.g., frustration tolerance) than did subjects in the control conditions. On the other hand, improvements in physical fitness were not related to reported improvements in abilities and confidence. These findings are of interest because they indicate that some of the important personal changes that are associated with physical fitness training are not due to changes in fitness, but appear to be due to other factors (e.g., group participation and expectancies).     

Preliminary evaluation of an after-school resistance training program for improving physical fitness in middle school-age boys

Most after-school physical activity programs for youth focus on aerobic games and activities. The purpose of this study was to evaluate the efficacy of an after-school resistance training program on improving the physical fitness of middle school-age boys. 22 boys (M = 13.9 yr., SD = .4 yr.) participated in a periodized, multiple-set, 9-wk. (2x/week) resistance training program. All subjects were pre- and post-tested on their 10-repetition maximum squat, 10-repetition maximum bench press, vertical jump, medicine ball toss, flexibility, and also percentage of body fat and the progressive aerobic cardiovascular endurance run (PACER). Statistical analysis indicated that subjects significantly improved performance on the squat (19%), bench press (15%), flexibility (10%), vertical jump (5%), medicine ball toss (12%), and the PACER (36%). Although this design minus a control group limits interpretation, this after-school resistance-training program can improve muscular fitness and cardiovascular fitness in boys and should be replicated with appropriate experimental controls.     

The Effects of Physical Exercise on Self-Attitudes

Research exploring the effects of physical conditioning on self-attitudes is reviewed. Conclusions from the studies are equivocal and depend upon subjects' emotional and physical status, the types of subjects, training programs, assessment tools, and subjects' psychological investment in the fitness programs. Although more research is needed to further elaborate the effective parameters of conditioning programs, general conclusions are that physical fitness is associated with enhanced self-attitudes in individuals, of all ages, who have physical and/or emotional disorders. Whether non-rehabilitation subjects show similar enhancement of self-attitudes depends upon their initial physical or psychological condition, their personality and the characteristics of the training program.     

Evaluation of physical activity measured via accelerometry in rural fourth-grade children

Interest in the benefits of exercise has prompted increased research examining the relationship between physical activity and health status in adults. More recently, considerable research effort has been directed toward the role of physical activity in young children as a precursor to adult physical fitness. The purpose of this study was to estimate the relationship between physical activity measured via accelerometry and body mass index, body mass, body composition, and physical fitness in fourth-grade boys and girls during physical education lessons. 54 fourth-grade students in rural Pennsylvania (28 girls, M age 9.6, SD = .56; 26 boys, M age 9.5, SD = .51) were subjects. Girls were significantly less active during all lessons measured (p < .001). The results of linear regression analyses indicated that physical activity was negatively associated with body mass index, body mass, and body fat percentage (p < .05), and positively associated with physical fitness (VO2max) (p < .01). These data indicate the need for curricular intervention to motivate girls to increase their activity during structured physical education lessons and demonstrate the efficacy of the body mass index as a screening tool within the schools.     

Effect of relaxation or exercise on undergraduates' test anxiety

The purpose of this study was to determine whether test anxiety could be significantly reduced through regular practice of relaxation exercises or physical exercise. Test anxiety was assessed at pretest and posttest using the 37-item true-false Test Anxiety Questionnaire developed by Sarason. 47 undergraduate students self-selected to participate. The 9 subjects in the group who engaged in a nonmeditative relaxation exercise 3 times per week for 7 weeks showed a significant decline in test anxiety. The 16 subjects in a supervised aerobic dance class 3 times per week for 7 weeks improved their fitness and their test anxiety significantly declined. The 20 control subjects did not meet over the 7-week study ahd showed no significant change in test anxiety, fitness, or relaxation.     

Systematic changes in perceptual reactance induced by physical fitness training

The effect of life-change events on perceptual augmentation-reduction was studied in 72 subjects (40 men, 32 women). In three experiments the kinesthetic figural aftereffect was measured prior to and after either a physical fitness program, a course in yoga, or training in Transcendental Meditation. Each program lasted a minimum of 8 wk. Subjects completing fitness training, all of whom were initially classified as augmenters, became reducers by the end of their program. Subjects enrolled in yoga and meditation courses remained relatively stable in their perceptual tendencies.     

Fear of fear,trait anxiety and aerobic fitness in relation to state anxiety during adrenalin provocation

Abstract

Psychological explanations of both spontaneous and experimentally induced panic anxiety stress the role of fear of fear, especially fear of bodily symptoms of arousal. Fear of fear is conceptually different from trait anxiety but may be associated with repeated experience of arousal symptoms in fearful situations, while frequent physical exercise may lead to habituation to these symptoms. To test this hypothesis, 44 healthy male volunteers, classified as having high or low trait anxiety and high or low aerobic fitness, underwent a single-dose adrenalin infusion (80 nanogram/kilogram bodyweight/minute). In both groups, during the experiment a significant rise in state anxiety was found; compared to the group with low trait anxiety, subjects with high trait anxiety reported higher levels of state anxiety, which could be attributed to differences in aerobic fitness. In the high-anxious group, subjects showed a greater decrease in state anxiety during the recovery phase. State anxiety during adrenalin was strongly associated with fear of bodily symptoms only in the high-anxious group. Correlations between trait anxiety and somatic anxiety were not significant; state anxiety scores tended to correlate negatively with physical fitness. It is concluded that these results lend support to a fear of fear-model of panic anxiety.     

The interplay of actual and perceived physical fitness in children: Effects on motivation and physical activity

From a sport and exercise psychology perspective, both the actual and perceived physical fitness become important for motivation towards physical activity and persistent physical activity in children no later than middle childhood (Stodden et al., 2008). To date, the effects of actual and perceived physical fitness have been investigated from a variable-centered approach (Jekauc et al., 2017). However, within this approach, the accuracy of the perceived physical fitness remains unconsidered. As actual and perceived physical fitness levels can be divergent, especially in children due to greater egocentricity and hence less comparison processes (Harter, 2006), also the accuracy of perceived physical fitness should be considered.In total, 462 children from 3rd and, approximately nine months later, from 4th grade participated in this study (M_age = 8.79 years). Third-grade students were assessed on their actual physical fitness, perceived physical fitness, and physical activity. In fourth grade, students were asked to fill out questionnaires that assess motivational regulations and physical activity. Polynomial regressions with response surface analyses were conducted to analyze main effects and accuracy effects of actual and perceived physical fitness on motivation and physical activity. Analyses revealed that children with higher actual and perceived physical fitness levels show greater autonomous motivation, higher current physical activity levels and higher physical activity levels nine months later. In addition, children who perceive their physical fitness more accurately show more current physical activity. Results indicate that the interplay between actual and perceived physical fitness does not only have an effect on physical activity but also on autonomous motivation, which is a predictor for long-term physical activity. Therefore, intervention should focus on the promotion of actual and perceived physical fitness. In addition, the ability to accurately assess fitness should be promoted in this age group.     

Use of self-reports of physical fitness as substitutes for performance-based measures of physical fitness in older adults

The purpose of the present study was to evaluate the association between self-reported physical fitness and performance-based measures of physical fitness in older adults. The specific components of physical fitness evaluated included aerobic endurance, muscular strength, and flexibility. Adults (25 men and 47 women) ranging in age from 56 to 92 years (M age=75 yr.) were recruited from the local community. Generally, the associations between self-reported and performance-based measures of physical fitness were low to moderate (r = 30-.01). Based on these findings, self-reports of physical fitness should not be used as substitutes for performance-based measures of physical fitness in older adults. Furthermore, present findings suggest that older adults, when asked to rate subcomponents of physical fitness, may not do so but rather evaluate a more general concept of physical fitness with aerobic endurance as the dominant factor.     

The relationship between physical fitness and inhibitory ability in children with attention deficit hyperactivity disorder: An event-related potential study

ObjectivesThe purpose of the current study was to examine the relationship between physical fitness and interference control by comparing higher and lower fitness children with attention deficit hyperactivity disorder (ADHD) using event-related potentials (ERPs) and behavioral indices.DesignCross-sectional design was employed.MethodEighty children, previously diagnosed with ADHD, were evaluated on their inhibitory ability as measured during their participation in the flanker task, and this ability was examined in relationship to measures of their physical fitness. Only children in the top 40% or in the bottom 40% of the distribution for each fitness components were included in the statistical analysis.ResultsThe results showed that children with higher levels of muscular endurance, muscular power, and aerobic capacity had shorter reaction times (RT) and larger P3 amplitudes compared to less fit children. In addition, children with lower body composition had shorter reaction times and shorter P3 latencies compared to those with higher body composition.ConclusionsBetter physical fitness, especially muscular endurance, muscular power, aerobic capacity, and body composition, were associated with enhanced interference control in children with ADHD. Our findings suggest the need for a closer examination of the possible impact of different aspects of fitness on the general relationship between physical fitness and cognition.     

Effects of physical conditioning on information-processing efficiency

This study investigated changes in information-processing efficiency that occur when physical fitness improves. Information-processing variables were Sternberg's memory-scan rate, Posner's name-access time, the Cattell Culture Fair Intelligence Test, and numbers of words remembered from word lists. At present and posttest 10 to 12 wk. later, 66 adults between the ages of 18 and 48 yr. took all cognitive tests and rode a bicycle ergometer to estimate physical fitness. A 2 X 2 (improved/stable fitness groups by pretest/posttest trials) analysis of variance with repeated measures indicated that the group who improved 15% or more in physical fitness improved significantly more on the name-access time than the group whose fitness remained stable. There was a trend toward improvement in memory-scan rate and number of words remembered on the first word trial by people who became more fit. The results may have implications for assessment and training of personnel in occupations where speeded perception and responses are required.     

Comparison of two exercise protocols on fitness score improvement in poorly conditioned Air Force personnel

A 12-wk. study was conducted to contrast the effects of a longer and more frequent aerobic exercise protocol with a shorter and less frequent circuit strength-training protocol for improving U.S. Air Force physical fitness test scores of subjects who previously failed to achieve a passing point total. 83 men and women of the U.S. Air Force (M age = 32.7 yr.) participated in either the unsupervised standard conditioning program, which recommended approximately 60 min. of aerobic activity 4 to 5 days per week (n=26), or the supervised circuit strength-training program, which required approximately 25 min. of alternating strength and endurance exercises 3 days per week (n=57). Subjects were assessed on a 2400-m (1.5-mile) run, abdominal circumference, push-ups completed in 1 min., and abdominal crunches completed in 1 min. Dependent t tests with Bonferroni adjustment indicated that significant improvements were attained by the circuit strength-training group only on each of the aforementioned measures. Significantly more participants in the circuit strength-training group (26%) achieved a passing point total than in the standard conditioning group (19%) at Wk. 12 (chi1(2) =3.96, p = .05). Implications for enhancing physical fitness in poorly conditioned adults were discussed.     

Perceived Fitness Predicts Daily Coping Better Than Physical Activity or Aerobic Fitness

This study sought to evaluate the association between perceived physical fitness, actual fitness measured by VO₂max, daily physical activity measured by an ambulatory activity monitor, and coping with daily stress. One hundred and thirty participants completed a series of questionnaires measuring perceived fitness as well as daily stress and coping levels each day for one week. Participants were also provided with a digital physical activity monitor (Yamax Digi-Walker SW 200) and instructed to wear it throughout the seven day assessment period. Upon completion of the week evaluation, participants then were evaluated for actual physical fitness by treadmill testing. Multiple regression and effect size analysis revealed that perceived fitness predicted daily coping better than actual fitness and daily physical activity. Coping was unrelated to age, gender,VO₂max, and physical activity. Results suggest that perceived fitness may be a better predictor of coping with daily stress than actual physical fitness or physical activity.     

Personality correlates of physical fitness

In this article, I examine the relation between personality and physical fitness. One group (N = 97) of male adults completed the Hogan Personality Inventory and five nationally recognized physical fitness batteries. A second group (N = 35) completed the Minnesota Multiphasic Personality Inventory and a set of medical and physical performance assessments. Results indicate that physical fitness must be defined in multidimensional terms and that fitness is related to self-confidence and self-discipline. Measures of psychopathology were unrelated to measures of health and fitness. These data suggest that the personal qualities associated with fitness are also those that promote and extend health.     

Percent body fat is related to body-shape perception and dissatisfaction in students attending an all women's college

The purpose of this study was to examine the influence of aerobic fitness, physical activity, percent body fat, and socioeconomic status on body-shape perceptions among 153 Euro-American students attending an all women's college. Using a set of nine female figure silhouette drawings arranged on an ordinal scale from very thin to very heavy, subjects chose the figure that approximated their Current, Ideal, Most Attractive shapes, and the shape they believed men found the most attractive (Male Attractive). Body Shape Dissatisfaction was assessed by the difference between Current and Ideal shapes. Several significant relationships were noted for body-shape perceptions with percent body fat, aerobic fitness, and physical activity. Overall, data indicate these relationships except for Male Attractive were confounded by percent body fat, as participants with a higher percentage of body fat preferred larger shapes and were more dissatisfied with their shape.     

Fitness, attitude toward physical education, and self-concept of elementary school children

Elementary school children scoring in the highest and lowest 26% or 27% of their classes on the Texas Physical Fitness test were compared for attitude toward physical education and self-concept. Data were collected on the Children's Attitude Inventory Toward Physical Education, a Game of Pairs for Preferences Among School Subjects, and the Children's Self-concept Scale. Analysis of variance indicated significant differences on all tests between boys high in fitness, girls high in fitness, boys low in fitness, and girls low in fitness. Subsequent Scheffé tests indicated that highly fit girls had significantly higher attitude and self-concept scores than boys low in fitness. Highly fit boys had higher self-concepts than boys low in fitness. No other group comparisons were significant. Pearson correlations indicated nonsignificant associations between fitness and attitude and self-concept for the four groups.     

Self-perception of health and fitness among French and Tunisian men and women

This work examines the effects of sex and culture on physical self-perceptions. The aim was to compare the perception of physical fitness of French and Tunisian men and women. 400 individuals ages 20 to 35 years assessed their own fitness, endurance, strength, flexibility, body composition, and health according to specific category scales by completing a questionnaire. In general, the Tunisian group rated themselves higher than the French group. It appears that perceived physical fitness was related mainly to perceived endurance for both groups. Some disparities were observed between the two nationalities. Analysis showed an interaction between sex and culture (French vs Tunisian). For French men and women and Tunisian men, perceived physical fitness was more associated with perceived endurance, whereas for Tunisian women, perceived physical fitness was more strongly associated with flexibility. These data show that self-perception of physical fitness is a dimension which varies between individuals from different cultures.     

Grip strength of Texas Special Olympians

Little is known about the physical fitness parameters of individuals who participate in the Special Olympics. The purpose of this study was to assess the grip strength of 104 Special Olympians participating in the winter Olympic Games. Men were significantly stronger than women across age groups 20 to 59 yr. Women's right hands were stronger than their left, while the opposite was true for men, despite the fact that 78.8% of the subjects reported right hand dominance. Mean right and left grip strengths were 25-40% less than the 1985 normative data of Mathiowetz, et al. by age groups. Special Olympian men and women have grip strengths comparable to elderly people rather than age-matched men and women.     

Effects of Florida's Personal Fitness Course on cognitive, attitudinal and physical fitness measures of secondary students: a pilot study

The effects of Florida's Personal Fitness Course were studied on 60 secondary students' cognitive achievement, physical fitness, and attitude toward physical activity. Significant improvement in knowledge of fitness concepts, selected physical fitness parameters, and over-all attitude toward participation in physical activity suggests the course was effective.     

Physical fitness,cognitive functioning and academic achievement in healthy adolescents

PurposeExamine the association between health-related physical fitness (cardiorespiratory fitness and muscular fitness) and skill-related physical fitness (speed-agility) and both cognitive functions and academic achievement in adolescents (12–15 years).MethodsData of 423 Dutch adolescents were analyzed (46.8% boys, age = 13.45 ± 0.43 years). Physical fitness was assessed using five subtests of the Eurofit test battery measuring cardiorespiratory fitness (20 m Shuttle Run Test), muscular fitness (Broad Jump and Sit-Ups) and speed-agility (10 × 5 m Shuttle Run Test and Plate Tapping Test). Cognitive functions were assessed by the Digit Span Task, the Grid Task and an adapted version of the Attention Network Test. Finally, academic achievement was assessed by two standardized tests assessing mathematic skills and language skills. Multilevel regression analyses were performed in MlWin to examine the relations of interest adjusting for sex and age.ResultsMultilevel regression analysis showed that speed-agility was significantly related to visuospatial working memory (β = 0.159; p = 0.014), information processing and control (β = 0.238; p < 0.001) and interference control (β = 0.156; p = 0.039), but not to the other cognitive or academic achievement outcomes. Cardiorespiratory fitness and muscular fitness were not related to any of the cognitive or academic achievement outcomes.ConclusionThe results suggest that skill-related physical fitness is related to cognitive functions and health-related physical fitness is not. Therefore it can be argued that improved levels of skill-related physical fitness may lead to improved cognitive functioning.
