| Abstract: | Important test components for performance evaluation, including assessment of
body composition, maximum aerobic capacity, heart rate and pulmonary function
evaluation are worth considering. The purpose of this study was to assess the
influence of Skinfold thickness and some selected cardiopulmonary parameters in
middle distance running performance. Twenty top-class middle distance runners (10
males, with Age = 18-26, Weight = 52-68kg, Height = 165-183cm, BMI (kg/m2) =
17.63-20.90; and 10 females with Age = 18-26, Weight = 41-57kg, Height = 157-
178cm, BMI (kg/m2) = 14.53-19.99) from Ethiopian Athletics Federation
volunteered to participate in the study. Skinfolds were measured at biceps, triceps,
sub-scapular and supra-iliac regions. Vital capacity (VC), Forced expiratory vital
capacity (FVC), Forced expiratory volume in the first second (FEV1), FEV1 %,
Peak expiratory flow (PEF), Maximum expiratory flow at 25% of maximal VC
(MEF25), Maximum expiratory flow at 50% of maximal VC (MEF50), Maximum
expiratory flow at 75% of maximal VC (MEF75), Maximum mid expiratory flow
between 25% and 75% of FVC (MMEF), Peak Inspiratory Flow (PIF) and Peak
Expiratory Flow (PEF) were measured by Spirometer. The maximal rate of oxygen
consumption (VO2max) was determined using a continuous, incremental exercise
protocol conducted on an electronically braked treadmill. Cardiotester belt was used
to measure heart rate at different level of treadmill testing. Correlation analyses
were applied to each variables and run time (performance). Performance was rated
by the scoring procedures of the International Amateur Athletic Federation (IAAF).
In male athletes, significant negative correlations were observed between skinfold
measurement at sub-scapular (r = 0.676, and P = 0.046), and supra-iliac (r = 0.798,
P = 0.01) and IAAF score. High negative correlation were found between sum of
four skinfold measures and IAAF score (r = 0.800, P = 0.010). In the female
athletes, high negative correlations were found between skinfolds measurement at
sub-scapular (r = -0.639, P = 0.047), supra-iliac (r = -0.751, P = 0.012), sum of four
skinfolds measurement (r = -0.778, P = 0.008), body fat percentage (r = -0.840, P =
0.002) and IAAF score.
There was a negative significant correlation between IAAF score and Percent Sub
Maximum Heart Rate (%HRmax) at 0.01 level of significance (r = -0.843 in female
and r = -0.865 in male) runners. VO2max (measured as ml/min/kg) was positively
correlated with IAAF score in male and female runners (r = 0.805, P = 0.003) (r =
0.859, P = 0.001). IAAF score was positively correlated (p<0.05) in the male
athletes with the following variables: VC (r = 0.65), FVC (r = 0.70), and FEV1 (r =
0.63). In female athletes IAAF score was also positively correlated with VC (r =
0.66), FVC (r = 0.85) and FEV1 (r = 0.80).
Results of this study suggested that lower skinfold thicknesses and sub maximal
heart rate were correlated with faster race time; higher lung volume and VO2max
are associated with faster run time. |
