Effects of different types of physical activity on the cognitive functions and attention in older people: A randomized controlled study.

This study aimed to evaluate the effects of different types of exercise on cognition. Eighty participants, 32 males and 48 females, aged 66.96 ± 11.73, volunteered for this study. The participants were randomly divided into the four following groups: Resistance Group (RG; n=20), involved in high intensity strength training; Cardiovascular Group (CVG; n=20), involved in high intensity cardiovascular training; Postural Group (PG; n=20) involved in low intensity training, based on postural and balance exercises; and Control Group (CG; n=20). Exercises were performed over the course of 12 weeks. All participants were tested for their cognitive functions pre- and post-intervention using the following neurocognitive tests: the Attentive Matrices Test, Ravens Progressive Matrices, Stroop Color and Word Interference Test, Trail Making Test and Drawing Copy Test. Statistical analysis showed that the CVG group improved significantly in the Attentive Matrices Test and Ravens Progressive Matrices (both p=<0.05), whereas the RG group improved in Drawing Copy Test time (p=<0.05). These results confirm that different types of exercise interventions have unique effects on cognition. Cardiovascular training is effective in improving performance attentive and analytic tasks, whereas resistance training is effective in improving praxis. Further investigation is necessary to evaluate the combination of the two exercise types in order to ascertain if their respective effects can be summated when performed together.

Participation in a 9-month selected physical exercise programme enhances psychological well-being in a prison population.

BACKGROUND There is general population evidence that physical exercise is effective in reducing the risk of depression and has positive effects on mood. Some prisons encourage exercise, but there is no evidence specific to this group on its benefits or the relative merits of different programmes. AIMS To test the effect of physical exercise on the psychological well-being of prisoners and to determine which mental disorders are most affected by physical activity. METHODS Sixty-four participants were randomly assigned across three groups: cardiovascular plus resistance training (CRT), high-intensity strength training (HIST) and no exercise. Before and after the 9-month experimental period, all participants completed the Symptom Checklist-90-Revised. RESULTS Each form of exercise significantly reduced depression scale scores compared with those in the control group, in which average depression scale scores actually increased. The CRT group also showed a significant decrease in GSI scores on the Symptom Checklist-90 and on its interpersonal sensitivity scale, whereas the HIST group also significantly improved on the anxiety, phobic anxiety and hostility scale scores. CONCLUSIONS Our evidence, taken together with general population studies, supports introduction of supervised, moderately intense exercise for at least 1 h per week for men in prison. They form a high risk group for mental disorders, and such exercise reduces depression and anxiety. Minimal special equipment is needed for CRT. Further research should replicate the study in a larger, multi-centre trial, and examine impact on shorter-term and longer-term prisoners, female prisoners and effects on recidivism.

Use of video observation and motor imagery on jumping performance in national rhythmic gymnastics athletes.

The aim of this study was to evaluate whether a mental training protocol could improve gymnastic jumping performance. Seventy-two rhythmic gymnasts were randomly divided into an experimental and control group. At baseline, experimental group completed the Movement Imagery Questionnaire Revised (MIQ-R) to assess the gymnast ability to generate movement imagery. A repeated measures design was used to compare two different types of training aimed at improving jumping performance: (a) video observation and PETTLEP mental training associated with physical practice, for the experimental group, and (b) physical practice alone for the control group. Before and after six weeks of training, their jumping performance was measured using the Hopping Test (HT), Drop Jump (DJ), and Counter Movement Jump (CMJ). Results revealed differences between jumping parameters F(1,71)=11.957; p<.01, and between groups F(1,71)=10.620; p<.01. In the experimental group there were significant correlations between imagery ability and the post-training Flight Time of the HT, r(34)=-.295, p<.05 and the DJ, r(34)=-.297, p<.05. The application of the protocol described herein was shown to improve jumping performance, thereby preserving the elite athletes energy for other tasks.

Psychological well-being and social participation assessment in visually impaired subjects playing Torball: a controlled study.

The aim of this study was to evaluate the differences in psychological well-being, symptomatic psychological disorders and social participation, between blind Torball players and non-players. Thirty blind male participants were recruited, 17 Torball players (aged 36.27±3.46) and 13 non-players (aged 34.80±2.53), and evaluated for social participation level, psychological well-being and symptomatic psychological disorders, using three validated self-report questionnaires: Participation Scale (PS), Psychological Well-Being Scale (PWBS) and Symptom Checklist 90 R (SCL-90-R) respectively. ANOVA showed significant overall differences between the two groups. The social restriction score in the non-player group was significantly higher (p<0.01) than the player group. The Torball player group showed significant better scores than non-player group in 5 of the 6 dimensions of the PWB Scale (p<0.01) and in 8 of the 10 dimensions of the SCL-90-R (7 dimensions p<0.01; 1 dimension p<0.05) and in the three global scores of the SCL-90-R (p<0.01). The results of this study showed a relationship between psychological well-being and social skills of visually impaired people and their Torball practice.

Mental health and social participation skills of wheelchair basketball players: A controlled study

The aim of this study was to assess differences in psychological well-being, symptomatic psychological disorders and social participation, between competitive wheelchair basketball participants and those non-participants. Forty-six wheelchair participants, 24 Basketball players (aged 35.60 ± 7.56) and 22 non-players (aged 36.20 ± 6.23), completed three validated self-report questionnaires: Participation Scale (PS), Psychological Well-Being Scale [PWBS] and Symptom Checklist 90 R [SCL-90-R]. ANOVA showed significant overall differences between the two groups. The social restriction score, evaluated by PS, was significantly higher in the non-basketball participants (p=0.00001) than the basketball participants. The PWB Scale showed significant differences in all 6 dimensions: positive relations with others, environmental mastery, personal growth, purpose in life and self-acceptance (p<0.01), and autonomy (p<0.05), with better scores in the basketball participants. The SCL-90-R scores were significantly lower for the basketball group in the following 6 symptomatic dimensions: depression, phobic anxiety, and sleep disorder (p<0.01), somatization, interpersonal sensitivity and psychoticism (with p<0.05). It was concluded that competitive wheelchair basketball participants showed better psychological well-being and social skills than those non-participants.

Effects of combined training vs aerobic training on cognitive functions in COPD: a randomized controlled trial

Aim The aim of this study was to investigate the effects of high-intensity aerobic training (AT) and high-intensity aerobic training combined with resistance training (ie, combined training [CT]) on cognitive function in patients with COPD. Methods Twenty-eight Caucasian male patients (68.35±9.64 years; mean ± SD) with COPD were recruited and randomized into two groups, AT and CT. Both groups performed physical reconditioning for 4 weeks, with a frequency of five training sessions per week. The CT group completed two daily sessions of 30 minutes: one aerobic session and one strength session, respectively; The AT group performed two 30-minute aerobic endurance exercise sessions on treadmill. Physical and cognitive function tests were performed before and after the training intervention performances. Results Exercise training improved the following cognitive functions: long-term memory, verbal fluency, attentional capacity, apraxia, and reasoning skills (P<0.01). Moreover, the improvements in the CT group were significantly greater than those in the AT group in long-term memory, apraxia, and reasoning skills (P<0.05). Conclusion CT may be a possible strategy to prevent cognitive decline and associated comorbidities in male patients with COPD.

Effects of resistance training on jumping performance in pre adolescent rhythmic gymnasts: a randomized controlled study

The aim of this study was to determine the effectiveness of two different resistance training programs on lower limb explosive and reactive strength in young female athletes. Fifty seven rhythmic gymnasts were randomly assigned to unspecific resistance training with dumbbells (12 repetition maximum squats) (n = 19; age = 12.0 +/- 1.8 years) or to specific resistance training with weighted belts (6% of body mass; n = 18; age = 11.9 +/- 1.0 years). Squat jump test, counter movement jump test, hopping test, flexibility of the hip, and anthropometric measures were assessed before and after six weeks training. The main result was that both unspecific resistance training and specific resistance training protocols positively affected the jumping performance, with an increase of the lower limb explosive strength of 6-7%, with no side effects. Counter movement jump flight time increased significantly (p < 0.01) while hopping test ground contact time significantly decreased (p < 0.01). No significant differences were detected among groups for flexibility, body mass, calf and thigh circumferences. Therefore, six weeks of resistance training that integrates different elements of rhythmic gymnastics training enhance jumping ability in young female athletes.

Different consecutive training protocols to design an intervention program for overweight youth: a controlled study

Objective To find the optimal exercise program to be recommended in reducing adiposity and promoting long-term physical activity adherence in a sample of overweight adolescents. Methods Forty-five overweight adolescents were randomly divided into three exercise groups, to perform two phases of physical activity as follows: in the first phase, the first group performed a 16-week moderate-intensity resistance training (RT), the second group performed a 16-week high-intensity RT, and the third group performed a 16-week aerobic training (AT); in the second phase, all groups performed a 6-week AT. Anthropometric body composition and fitness measures were considered as outcome measures. Results After the second protocol, both RT groups showed a significant improvement in percentage of fat mass (F2,76 = 5.843; p = 0.004; h2 = 0.133) and free fat mass (F2,76 = 6.254; p = 0.003; h2 = 0.141), and in fitness tests (p < 0.01). The VO2max values of the RT groups were significantly higher than those of the AT group (F2,38 = 4.264; p = 0.021; h2 = 0.183). The rate of adherence to exercise was an average of 94% in both RT groups, whereas in the AT group, it was 83%. During the 12-week post-intervention follow-up, the number of participants who continued to perform physical activities was significantly higher in both the RT groups than in the AT group (p < 0.05). Conclusion The present study provides preliminary evidence that moderate-to-intense RT, followed by AT, can be an effective treatment for overweight adolescents, and the positive effects are maintained even after 12 weeks of follow-up.

Time-of-Day Effects on Static and Dynamic Balance in Elite Junior Athletes and Untrained Adolescents:

The aim of the present study was to analyse the daily variation of balance in two groups of female adolescents: elite athletes (n=20, aged 13.2 ± 0.5 years) and untrained students (n=20, aged 12.9 ± 0.6 years). Participants underwent two testing sessions over two days at two different times each day. Morningness-Eveningness self-assessment questionnaire was administered to assess the chronotype of the participants and oral temperature was measured too. Significant group differences were found in the overall balance tests (p<0.01). Athlete group showed no significant differences in balance tests with respect to the time-of-day. Untrained adolescents attained better results in the morning in the dynamic balance tests (p<0.01). No correlations were found between chronotype, oral temperature variations and balance tests scores. The main outcome of the study was that elite athletes did not show time-of-day effects on balance, whereas the untrained adolescents achieved better results in the morning.
