The Relationship

The aim of this study was to investigate the relationship between 60m sprint results and reaction times in athletes who took part in the World Indoor Athletics Championships. The reaction times and 60m sprint results were compiled for 483 sprinters (253 male, 230 female) who performed 60m sprint event. Corresponding data were obtained from archives of the official website of the International Association of Athletics Federation (IAAF). The relationship between reaction time and 60m sprint results were calculated using Pearson correlation coefficient. Additionally, the Independent Samples T-Test was used to compare athletes’ reaction times and 60m sprint results. Positive moderate correlation was found between mean values of all 60m sprint results and reaction times, which were analyzed together in all categories (r=.436, p<0.01). Moreover, significant differences were also found between male and female finalists based on the 60m sprint times and reaction times respectively (t=-27.98, p<0.01; t=-3.26, p<0.01). As a result, it can be concluded that reaction time has great importance on 60 m performance. The best reaction time is related to the higher performance of 60m sprint in both male and female athletes. Moreover, this is also similar for round 1, semifinal and final categories. Coaches and athletes may consider improving reaction time to achieve better 60m performance.

The Relationship

This article examines elite athletes’ understandings of the relationship between sport participation and health. Data are taken from interviews with 20 male and female athletes. Athletes’ assessments of the impact of sport on health and wellbeing include attributions of negative, positive, and, most often, mixed outcomes. In these elite athletes’ conceptualizations of health, injury and illness are subordinated to a view of health as capacity, and the primary frame of reference in which they consider capacity is their immediate competitive careers. Respondents’ accounts of efforts to manage the threats to their health that are posed by their sporting activity frequently convey a disembodied notion of the athletic body as an object to be managed.

Minimum Intensity

Purpose The minimum masking level (MML) is the minimum intensity of a stimulus required to just totally mask the tinnitus. Treatments aimed at reducing the tinnitus itself should attempt to measure the magnitude of the tinnitus. The objective of this study was to evaluate the reliability of the MML. Method Sample consisted of 59 tinnitus patients who reported stable tinnitus. We obtained MML measures on two visits, separated by about 2–3 weeks. We used two noise types: speech-shaped noise and high-frequency emphasis noise. We also investigated the relationship between the MML and tinnitus loudness estimates and the Tinnitus Handicap Questionnaire (THQ). Results There were differences across the different noise types. The within-session standard deviation averaged across subjects varied between 1.3 and 1.8 dB. Across the two sessions, the Pearson correlation coefficients, range was r = .84. There was a weak relationship between the dB SL MML and loudness, and between the MML and the THQ. A moderate correlation ( r = .44) was found between the THQ and loudness estimates. Conclusions We conclude that the dB SL MML can be a reliable estimate of tinnitus magnitude, with expected standard deviations in trained subjects of about 1.5 dB. It appears that the dB SL MML and loudness estimates are not closely related.

Elementary Cognitive Tasks

Effects of four retest-practice sessions separated by 2 h intervals on the relationship between general intelligence and four reaction time tasks (two memory tests: Sternberg's memory scanning, Posner's letter comparison; and two attention tests: continuous attention, attention switching) were examined in a sample of 83 male participants. Reaction times on all tasks were shortened significantly. The effects were most pronounced with respect to the Posner paradigm and smallest with respect to the Sternberg paradigm. The relationship to general intelligence changed after practice for two reaction time tasks. It increased to significance for continuous attention and decreased for the Posner paradigm. These results indicate that the relationship between psychometric intelligence and elementary cognitive tasks depends on the ability of skill acquisition. In the search for the cognitive roots of intelligence the concept of learning seems to be of importance.

Magnitude Estimates

An experiment was conducted to compare visual reaction time and visual brightness within the same subjects. Simple reaction times and magnitude estimates of brightness were obtained in response to 1000-msec. flashes of 60.7, 67.5, 76.4, 85.1, and 93.4 dB re 10−10L white light. The relationship between reaction time and stimulus intensity was best described by a negative logarithmic function, while the relationship between magnitude estimates of brightness and stimulus intensity was best described by a power function. Linear correlations between reaction times and magnitude estimates indicated that visual reaction time and brightness are not proportional within all subjects. Previous reports of proportionality between these two measures were discussed as possibly being the result of inappropriate cross-experiment comparisons.

The Relationship

There were two main purposes in the present study. The first was to identify the nature of the self-handicaps reported by elite female and male athletes (N = 245). School commitments and sport problems represented the most frequently cited impediments. Female athletes reported a significantly greater number of disruptions and had a greater tendency to report that sport problems, physical state/illness, and family/friend problems hindered their preparation. The second purpose was to determine whether cohesion would moderate the extent to which athletes would use self-handicapping strategies prior to competition. Hierarchical multiple regression revealed that cohesion was a moderator in the relationship between the trait of self-handicapping (Excuse Making) and the use of self-handicapping for both female and male elite athletes. Results of post hoc analyses indicated that athletes who were highly predisposed to self-handicap and who perceived their group as more cohesive, had a greater tendency to proactively perceive impediments to subsequent performance.

The Relationship

Pain signals threat and initiates motor responses to avoid harm. The transformation of pain into a motor response is thus an essential part of pain. Here, we investigated the neural mechanisms subserving the sensorimotor transformation of pain at the cortical level by using electroencephalography. In a simple reaction time experiment, brief painful stimuli were delivered to the left hand of healthy human subjects who responded with button presses of the right hand. The results show that the simple reaction time task was associated with neuronal responses at delta/theta, alpha/beta, and gamma frequencies. The analysis of the relationship between neuronal activity and response speed revealed that gamma oscillations, which were temporally coupled to the painful stimuli, but not temporally coupled to the motor response, predicted reaction times. Lateralization of gamma oscillations indicates that they originate from motor areas rather than from sensory areas. We conclude that gamma oscillations are involved in the sensorimotor transformation of pain whose efficiency they reflect. We hypothesize that the relationship between stimulus-locked gamma oscillations and reaction times reflects a direct thalamo-motor route of nociceptive information that is central to the biological function of pain.

The aim of this study is to analyze the attention capacity and the reaction time in Portuguese karate Shotokan athletes. Participated 96 Shotokan athletes from the Portuguese Karate Association. We physically characterized the sample (weight, height, body mass index, and body fat mass percentage) and evaluated Simple Reaction Time (TRS), Choice Reaction Time (TRE), Decision Time (TD) and the Distributed Attention (AD). Data was analyzed according to athletes’ group age (15 to 19 yr, 20 to 35 yr and more than 35 yr), level of graduation (9<sup>th</sup> to 4<sup>th</sup> kyu, 3<sup>rd</sup> to 1<sup>st</sup> kyu, DAN) and by gender (male and female). Male athletes present significant differences from female athletes in height, weight, years of practice and body fat mass. In relation to TRS all groups tend to a value near to 300 ms without significant differences among them, but the TRE and the TD are significantly higher in the Dan athletes and in the +35 yrs athletes than in the other groups. On the other hand the Dan and +35 yrs athletes tend to do less mistakes. Gender does not influence significantly the reaction time in the Shotokan karate athletes, but it seems that women tend to have smaller reaction times than men. Athletes with more years of practice and more graduation need more time to reply to the stimulus than the other athletes, but they tend to do fewer mistakes on their choices than other subjects. As for distributed attention, no significant differences were found in function of the athlete graduation, nor in function of gender. However, for distributed attention, we found statistical significant differences in function of the age, with the oldest athletes presenting lower levels of distributed attention. Our results seem to show that is necessary to do some modifications in the training process of Portuguese Shotokan karate athletes.
