Study was conducted in order to examine effect of 6-week competition period boxing trainings on peak anaerobic strength, fatigue and recovery levels. 6 female boxers whose age average was 21,16±0,75 and who were students of Faculty of Sport Sciences in Selçuk University, participated in the study as volunteer subjects. Before and after 6 weeks of training, subjects' peak anaerobic strength, peak relative anaerobic strengthand fatigue indexes were measured by using Monark 824 model (made in Sweden) wingate arm ergometer. Before and after arm wingate anaerobic strength test, fatigue and recovery levels of subjects were measured by using lactate scout (Lot:0443401, Made in Germany) device and Polar RS800 (Made in Finland) device in 10 different time periods (resting, fatigue, after 1 min, after 3 min, after 6 min, after 9 min, after 15 min, after 30 min, after 60 min, after 90 min). While making statistical analyzes of data, paired-t test was used in order to determine the difference between pretest and posttest values. In the parameters measured; fatigue index and peak anaerobic power levels between pretest and posttest are similar, there are significant increase in peak relative anaerobic strength level (p<0,05). There is no difference between pretest and posttest lactate timings. HR (heart rate) posttest resting value is significantly lower than pretest resting value (p<0,05), other timings are similar. Consequently; it can be said that 6-week competition period boxing training improves lactate tolerance and threshold in female boxers and there is an increase in peak anaerobic strength, in addition, it contributes to fatigue and recovery levels.
