Objective: The aim of this study was to investigate some physical fitness factors after eight weeks of strength and speed training in young karatekas.
Method: This semi-experimental study was a double-blind, double-blind study with 33 male karatekas, with a mean age of 22.2±2.2 years, randomly divided into three equal groups (resistance training, speed training, and control groups). Strength and speed training was three sessions per week for eight weeks. Before and after the training period, the subjects were measured for flexibility in centimeters and hamstring muscle strength in kilograms. The mean and standard deviation were used to describe the data statistically. After determining the normality of the data using the Kolmogorov-Smirnov test, the independent t-test was used to compare the variables of a group and the one-way analysis of variance test with Tukey's post hoc test was used to analyze the data. The analysis was performed at a significance level of p≥0.05.
Results: The findings showed a significant difference after strength and speed training in flexibility and strength factors (p = 0.0036). Also, the results of one-way analysis of variance showed that there was no significant difference between these two types of training in terms of flexibility (p = 0.75), but this difference was significant in strength (p = 0.0024).
Conclusion: Based on the results of this study, strength and speed training can help improve the flexibility and strength of the hamstring muscles. However, it seems that resistance training acts as a more effective method to strengthen these muscles.
