دلائل التلف العضلي و استجابته الكيميائية و الوظيفية لدى الممارسين و غير الممارسين للنشاط الرياضي من طلاب جامعة طيبة

Abstract EN

The level of athletic performance in various sports activities is significantly dependent on the type of muscles used in the training process.

This study aims at identifying signs of muscle damage and its biochemical and functional response in skeletal muscles to sports-activity amongst practicing and non-practicing students at Taibah University.

The study was conducted on a sample of 30 basketball players during the academic year 2012/2013.The arithmetic mean of the respondents age was 23.721±1.379 years, the average height was 195.967±6.020 cm and the average weight was 93.649±3.755 kg.

Respondents were divided into two groups; one suffering from muscle damage and another healthy group.

Different tools and equipment were used to identify the level of urinary MDA, CK and LDH enzymes and the level of physiological response to lactic acid, heart rate, vital capacity and blood pressure.

The study revealed high indicators of damage to the muscles and reduced functional responses among the non-practicing participants (unhealthy group), as well as an improvement in all the vital biochemical indicators of muscle damage in the healthy group.

The study showed the appearance of biochemical and functional responses in games and tournaments when nonpracticing participants make physical efforts of high intensity resulting in higher muscle damage.

The study recommends the application of such an investigation study on the youth to prevent excessive physical effort.
