الملخص EN

A comparative study in the legs explosive strength and maximum strength after strength training using weight and plyiometric training.

One of the main objectives of the college of physical education is promoting the physical fitness of students.

The past few years witnessed an obvious neglect of school sports in general and students of physical in particular.

The suffering starts when such students are accepted to study in physical education colleges because they lack the least fitness, especially the strength required for most of the sports activities taught in the colleges curriculum (i.e Volleyball, basketball, handball, football and track and filed events and a number of skills including gymnastics and swimming).

The study aims at expound ting the following : 1.

The differences in strength training in pre-tests and post-tests.

2.

The differences in plyiometric training in pre-tests and post-tests.

3.

The differences in both strength and plyiometric training in pre-tests and post-tests.

The researchers adopted the experimental method appropriate to the nature of the study.

The population of he study consisted of students from the college of physical education which are (200) students and the selected samples were (44) divided into two groups.

The tests used were long jump from standstill and maximum strength of legs and the measures of height and weight .The researchers used (arithmetic means, standard deviation and T-Test).

The most important conclusions of the study : 1.

Significant differences exist between the pre-test and post-test in favor of the post-test in using plyiometric training.

2.

Significant differences exist between the pre-test and post-test in favor of the post-test in using weight training.

3.

Significant differences exist between the pre-test and postest- in using each of the plyiometric and weight training in favor of the plyiometric training.
