An analysis of resistance training history in ultramarathon runners and implications on performance

Background and Study Aim: The aim is to evaluate the effect of resistance training without balance exercises on the static balance skill. Material and Methods: The universe of the study consists of volunteer students who are chosen among the students with similar physical characteristics and training history (n=15) who are taking education at Istanbul Gelisim University, High School of Physical Education and Sports (n = 1286) who have any current health problems and disability history. An information form questionnaire (age, height, and weight, training history) was applied as a personal data collection tool. Static balance skill of the participants tested through AC International East Sp. Z O.O. which has the brand of– SIGMA Balance Platform which is found at performance measurement and evaluation laboratory of Istanbul Gelisim University, High School of Physical Education and Sports. Test procedures were applied before and after the 6-week resistance training program. Results: Statistically significant differences were detected in test values of Static balance skill x axis deviation rate of the study group, rate of deviation from the center in the x axis, the length of distance and average surface area which is used (P<0,05).Conclusions: It was identified that 6-week resistance training practices without balance exercises have a positive effect on the development of static balance skill.

The purpose of the study was to investigate the magnitude of bilateral deficit (BLD) in trained males and examine its relationship with functional performance and recent resistance training history. Ten physically active males (age: 23.02±1.27 years) self-reported the number of unilateral and bilateral exercises within their structured resistance training schedule. During two visits to the laboratory, participants performed unilateral and bilateral squat jumps (SJ) and isometric leg extensions (ILE) for the quantification of BLD. Participants also performed bilateral countermovement jumps (CMJ) and a change of direction (COD) test to quantify functional performance. The performance outcomes and information regarding training history were then correlated with the bilateral index (BLI) metric. The key findings were that: (a) a lower BLD in SJ peak power related to a greater CMJ peak force (r=.728; p=.02) and peak power (r=.750; p=.01), (b) the BLI in the ILE was unrelated to performance outcomes, and (c) BLI was unrelated to the mean number of bilateral and unilateral exercises in the structured resistance training programme of participants. In conclusion, lower levels of BLD may be advantageous for bilateral tests of functional performance (i.e. jumps) however there is a need to consider the mechanical similarity between the performance and BLD measure. Finally, the balance of unilateral and bilateral exercises in an individual’s recent resistance training history is not sensitive to the BLI measured during dynamic or isometric assessments.
