Determining the endurance performance in women futsal players during the season of preparation and competition

14 of the Duzce University women futsal players (training age 5.14±0.86years, age 21.28±1.38year, height 163.28±4.87cm, and body weight 54.30±5.33kg) participated voluntarily in our study aimed at determining the endurance performance in women futsal players during the period of preparation and competition. Height, weight and body mass index (BMI), Yo-yo intermediate recovery test 1 (YIRT1), repeated sprint ability (RSA) and fingertip lactate measurement are used for determining body compositions, aerobic capacities, anaerobic capacities and lactate concentrations of players respectively, whereas Polar V800 device is operated for making firm of heart rate during the tests. For statistical evaluations, it is benefited from SPSS software package. At pre-test of women futsal players during the preparation season, Body weight, BMI, body fat percentage, maximal oxygen update (VO2Max), travelled distance, lactate after YIRT1, fatigue time, fatigue index, recovery pulse and lactate values after RSA are determined as follows: 54.30±5.33kg, 20.38±2.04kg/m2, %17.52±3.57, 40.36±1.16ml/kg/min, 471.42±138.72m, 11.22±1.60mmol, 1.50±0.77sc, %8.15±2.79, 132.07±10.00pulse/min, 11.87±1.59mmol; at post-test these values are 52.06±5.38kg, 19.53±2.05 kg/m2, %15.65±4.08, 41.60±1.14ml/kg/min, 620.00±136.55m, 13.76±1.88mmol, 0.88±0.41sc, %5.92±2.98, 122.64±8.22pulse/min, 13.35±1.28mmol, respectively. As a consequence of our study, It is found that there are significant statistical differences between test results at preparation season and at competition season when performances of women futsal players are evaluated (p<0.01). According to spearman correlation test results, P-values have been found out to be p<0.05 between lactate and recovery speed, p<0.01 between recovery pulse, p<0.01 between VO2Max and recovery time and p<0.05 between fatigue indexes. Likewise, the statistical differences between recovery time and fatigue index and between best times are p<0.05 and p<0.01 levels respectively.
