CHRONIC EFFECT OF INSPIRATORY MUSCLE TRAINING TO MAXIMAL EXPIRATORY PRESSURE IN SEDENTARY HEALTHY BOYS

The aim of this study was to investigate the effect of inspiratory muscle training on maximal expiratory pressure (MEP) in healthy sedentary boys. For this purpose, 20 healthy sedentary boys aged 12 years were randomly assigned to two groups as inspiratory muscle training group (IMT, n = 10) and control group (CG, n = 10) who did not perform any training. 30x2 breath exercises were performed as inspiratory muscle training for 4 weeks and 3 days a week for 40% maximal inspiratory pressure (MIP). The MEP test was applied to all subjects 1 day before and after 4 weeks. The data were analyzed in SPSS 22.0 program. The mean of the percentage change with 2x2 mixed factor ANOVA and LSD correction tests were investigated with Mann Whitney U test. As a result of the statistical analysis, a significant difference was found between the IMT pre-and post-test results at the MEP value (p <0.05). In addition, it was observed that IMT showed a significant increase when compared to CG (p <0.05). In conclusion, it can be said that inspiratory muscle training affects the maximal expiratory pressure positively in healthy sedentary boys.  Article visualizations

THE EFFECT OF 4-WEEK TWO DIFFERENT STRENGTH TRAINING PROGRAMS ON BODY COMPOSITION

The purpose of the study was to investigate the effect of the four-week two strength training program on the skin fold thickness and body fat percentage (BFP) characteristics according to the maximal strength and strength endurance principles. Sixteen male volunteers participated in the study. The subjects were divided into two groups as the maximal strength group (MSG, n=8, Age=24.00±3.78 year, Height=172.25±2.19 cm, Weight=75.13±6.60 kg) and the strength endurance group (SEG, n=8, Age=25.13±3.09 year, Height=173.38±2.62 cm, Weight=77.00±7.54 kg). 4 weeks training program was applied to maximal strength group according to maximal strength training principles and applied to strength endurance group according to strength endurance training principles. In both groups, body weight, body mass index (BMI), skin fold thickness (triceps, biceps, pectoral, subscapula, abdominal, suprailiac, femur anterior and posterior, calf) and body fat percentage measurements were taken one day before and after the 4 week period. Between pre-test and post-test of SEG group, significant change was showed in triceps, biceps, pectoral, subscapula, abdominal, suprailiac, femur anterior and posterior skin fold thickness measurements and VFM parameters (p < 0.05). Significant change was determined in pre-test and post-test of MSG group in triceps, pectoral, subscapula, abdominal, suprailiac, femur anterior skin fold thickness measurements and VFM parameters (p < 0.05). When the pre-post test differences of the groups were compared, no difference was found between MSG and SEG groups (p > 0.05). As a result, it can be said that 4-week maximal strength training and strength endurance training have positive effects on the skin fold thickness and body fat percentage parameters.  Article visualizations
