The effect of fatiguing exercise on balance performance as measured by the balance error scoring system

The aim of the study was to investigate whether a fatiguing exercise on treadmill affects balance performance in recreationally active men and women. Nineteen subjects, aged 18-26 years, were assessed before and after a fatiguing exercise, using the Balance Error Scoring System (BESS). Fatiguing exercise was performed on treadmill using the Bruce protocol. A significant effect of fatigue was present in men ( P 0.05). These findings suggest that a fatiguing exercise induced by means of treadmill increases postural sway in healthy subjects, and that this increase in postural sway is sex-independent.

Relationships between Balance and Functional Performance in Football Players

Relationships between Balance and Functional Performance in Football Players The aim of the present study was to examine the relationships between balance performance as measured by the Balance Error Scoring System and functional performance in football players. Twenty-two football players from University League Final Group in Turkey (age 23.05 ± 1.65 years, height 176.58 ± 6.99 cm, weight 68.80 ± 7.00 kg) volunteered to participate in the study. Postural performance was measured by the Balance Error Scoring System (BESS). For functional performance, standing broad jump, triple-hop, vertical jump, four-line sprint and three-corner run test were used. There was not a statistically significant relationship among the all BESS scores and triplehop in non-dominant leg, power, four-line sprint, and three-corner run performances (p<0.05). Triple-hop in dominant leg performance correlated with foam surface, tandem leg and total BESS score (r = 0.755, p < 0.01; r = 0.664, p < 0.05; r = 0.713, p< 0.01, respectively). Standing broad jump performance correlated with foam surface, tandem leg and total BESS score (r = 0.737, p < 0.01; r = 0.692, p < 0.05; r = 0.617, p< 0.05, respectively). There was a statistically significant relationship among the single leg BESS score and vertical jumping performance (r = -0.596, p<0.05). In conclusion, the activities requiring explosive power may reflect the ability of managing a balanced posture but the activities in which time period is longer may not.

The effect of ankle taping on isokinetic strength and vertical jumping performance in elite taekwondo athletes

The aim of the study is to examine the effect of ankle taping on ankle plantarflexion (PF) and dorsiflexion (DF) isokinetic strength and vertical jump height in elite taekwondo athletes. Seven women and 9 men taekwondo athletes forming the Turkish National Taekwondo Team participated in this study. A closed basket weave taping technique was applied to the dominant and non-dominant ankle. Tests were performed both in un-taped and taped conditions. Peak torques values at 60 and 180 ◦ /s were nonsignificantly lower in the taped condition ( p> 0.05). Ankle taping resulted also is a significant reduction in jump height ( p< 0.05). The findings of this study suggest that ankle taping affect detrimentally performance in this group of taekwondo athletes.

Balance Performance and Recovery After Exercise With Water Intake, Sport Drink Intake and No Fluid

The objective of the present study was to determine the effects of exercise with water intake, sport drink intake and no fluid on balance performance and recovery. Seventeen physically active men (age, 22.29 ± 1.61 years; height, 176.24 ± 5.18 cm; weight, 69.47 ± 9.20 kg) volunteered to take part in this study. The Biodex Balance System was used to evaluate balance performance and Overall Stability Index (OSI) scores were used to assess balance performance. The exercise protocol consisted of a 1-hour exercise session at 75% and 85% of maximal heart rate. The recovery period was 20 minutes of rest without fluid intake. In all experiment conditions, balance tests were applied three times as pretest, posttest and recovery. In each one of the three experimental conditions, balance tests were consecutively performed with eyes open and eyes closed. All the measurements and exercise protocols were performed in the morning (between 9 AM and 12 PM), in a specially designed and equipped room, with room temperature at 21–24°C. Repeated-measures ANOVA was used to examine all the conditions. OSI post-exercise was significantly higher than pre-exercise ( p p
