Abstract:
The main objective of the study was to investigate the “effect of weight training on muscle
mass and strength of under 17 male box sport project of Harari regional state, Ethiopia
“In this study multistage sampling technique method was used to select 60 target group.
The first sampling method used to define subjects was availability then to place the
athletes in to groups simple random sampling was used. Experimental and control groups
was used and 12 weeks of strength training was delivered for the experimental group
while the control group was excluded from the training. Data collected from body weight,
chest circumference and waist circumference to check their body mass change and press
up, standing long jump and 1 maximum repetition weight lifting was used to check their
strength change before and after intervention. The data obtained was analyzed using
simple descriptive statistics (frequency, mean ± Standard Division) and independent
samples t-test (Mean Division, Standard Division mean and at significance levels) and
evaluated the point with Post-test of mean value to each variable’ tests. were Mean ±
Standard Division value of chest circumference, (Body Mass Index) test (point-78.20
±3.4972, point -79.4667±3.9379), body weight (point 65.6533 kg ±4.2165, point
- 68.0333 bpm±4.5022), waist circumference (point - 69.50 ±4.044, point - 71.6912
±4.058) 1 maximum repetition weight lift (point - 73.04 ± 5.044, point - 76.3333 ±4.658)
standing long jump (point - 2.5512 ±0.1397, point - 2.8325 ±0.2531) and press up (point -
29.5624 ±7.365, point - 34.4167 ±7.8011) of the target group were registered respectively
after 12 weeks continue strength exercise training program, which was indicated the
improvement of muscles mass and muscle strength of the target group. The result obtained
in this study indicated that there was a significant improvement in all the variables. The
study concluded that the effect of strength exercise training programs had a significant positive effect on the improvement of muscles mass and muscle strength of participants.
Based on the finding, the researcher recommended that it is quite clear that further
research is necessary on the title of ‘effect of weight training on muscle mass and strength
of under 17 male other sport project of Harari regional state, Ethiopia
