Abstract: External counterpulsation (ECP) is a safe and effective non-pharmacological therapy for the treatment of refractory angina pectoris and coronary artery disease. Emerging evidence suggests that a single ECP session may be beneficial for exercise performance and markers of recovery; however, findings have been mixed. Furthermore, it is unknown how multiple sessions of ECP influence performance and short-term recovery after repeated, daily exercise. Fifty-seven healthy adults (27 male, 30 female, 38.9 ± 11.6 years) completed three consecutive daily study visits consisting of a weighted lower-body exercise circuit and a 10k cycling time trial. Measures of recovery included balance and jump (height and explosiveness) performance, which were assessed before the exercise circuit (PRE) and following the cycling time trial (POST). Participants randomly assigned to the treatment condition received 30 minutes of ECP therapy each day, while control participants received 30 minutes of sham treatment. Repeated measures ANOVA was used to examine within and between group differences on measures of recovery and cycling time trial performance. Participants that received ECP treatment each day after strenuous exercise for three days showed improved cycling time (p = .006) and balance performance (p < .001), whereas control participants demonstrated decreased jump explosiveness performance (p = .014). Results of this study provide preliminary evidence that ECP therapy may be beneficial for use in exercise recovery and performance in healthy adult populations.

Abstract: The aim of this study is to identify the level of accuracy in penalty kicks using different techniques of performance analysis in the Egyptian Football League by making a comparison between two models of analysis techniques used, Two models were used: (Korstat XG) and (Instat XG). The researchers used the descriptive survey method for a sample of the Egyptian Football League (10) teams. The appropriate statistical method was used using the statistical analysis program Spss. The most important results of this study were the following: We note from the table that instat, which gives the penalty kick value of 0.75, is the closest to the accuracy, as its accuracy of expecrltation during five seasons reached 99.94% after it was expected that 493.5 penalty kicks were scored, while 491 penalty kicks were actually recorded. On the other hand, the KoraStat model, which gives the penalty kick a value of 0.89, has an accuracy of expectaion 83.84%, after it was expected to score 585.63 penalty kicks, while 491 penalty kicks were actually recordedWhich shows that the value of scoring a penalty kick in the Egyptian League corresponds more to the model of the company Instat, which gives for each penalty kick a value of 0.75 as an expected goal.
