“…Post-exercise effects on the m-CTSIB yielded similar result to previous literature using the BESS test, with decreased overall performance post-exercise [6,9,11]. While the BESS uses subjective, human-scoring, fatigue plays a pivotal role in establishing and controlling balance and postural stability [24][25][26]. Since the m-CTSIB also examines sensory integration, the results are partially supported by previous research reporting that vestibular and visual integration remained unaffected by exercise on the NeuroCom Sensory Organization Test, despite somatosensory differences [15].…”

Effects of exercise on symptoms, vestibular/ocular motor screening and postural stability in a college-aged sample

Aim: To examine the effects of maximal exercise on symptoms, vestibular/ocular motor screening (VOMS) and postural stability. Methodology: A total of 17 college-aged individuals completed a symptom scale, VOMS and the modified Clinical Test for Sensory Interaction and Balance (m-CTSIB), followed by a graded maximal exercise treadmill test. Assessments were repeated post exercise, 20 and 40 min post-exercise. Results: Significant increases in total symptoms, symptom severity scores and m-CTSIB scores from baseline to immediate post exercise were reported. Following 20-min recovery, improvements were noted on symptoms, visual motion sensitivity on VOMS and m-CTSIB. Conclusion: Symptoms and postural stability are influenced by exercise and following 20 min of rest, returned to baseline, indicating that a period of 20 min following a suspected concussion may be needed to negate exercise effects.

“…It was observed that the best elite rifle shooters and archers also had the best postural performance (Ball et al, 2003; Musa et al, 2018). By holding their rifles with their arms, rifle shooters create a trunk-head-arms block that must be well interlocked to limit the movements of the rifle and to enable the best possible shooting score (Bermejo et al, 2015). Hence, Ball et al’s result is not surprising since body sway (evaluated through displacement of COP) is likely to be transmitted to the motion of the gun and aim point and is thus likely to affect shooting performance.…”

The review addresses the relationship between sport expertise (i.e., sport competition level), postural performance (amount of motion of the center of mass/of pressure of foot or ability to preserve body balance), and postural strategy (geometric organization of different body segments as well as neurobiological involvement of organism). Since the conditions of postural evaluation are likely to influence results, the aim is to compare athletes at different competition levels in ecological postural conditions (specific postural conditions related to the sport practiced) and non-ecological postural conditions (decontextualized postural conditions in relation to the sport practiced). Evidence suggests that the most successful athletes in terms of sport competition level have the best postural performance both in ecological and non-ecological postural conditions. However, in non-ecological conditions, the postural tasks should be preferentially challenging or relatively close to the sport practice stance. Moreover, the most successful athletes also have more elaborate postural strategies compared with athletes at lower competition level. Mechanistic explanations as well as conceptual models are proposed to explain the role of different factors influencing the relationship between sport expertise and postural performance and strategy.

“…On the other hand, biathletes exercise at very high physical loads, with heart rates (HR) of 90% of their maximal capacity while skiing, and 85%–87% when approaching the firing line (Hoffman & Street, 1992). Crucially, intense physical exercise is known to affect postural balance (Paillard, 2012), especially when standing and holding an additional weight such as the rifle (Bermejo et al., 2015).…”

This study examined the influence of physical exercise on the relation between shooting accuracy and the phase of the cardiac cycle in which the shot is fired. Thirteen experienced biathletes (8 females, mean age 17 years) fired from the standing position at rest and right after a submaximal exercise on a bicycle ergometer. Shooting accuracy and the timing of each shot relative to the R-waves of the electrocardiogram (ECG) were recorded. Best shots (with greatest accuracy) and worst shots (with lowest accuracy) were fired prevalently in different phases of the cardiac cycle. In the rest condition, best shots were fired less frequently from 200 to 300 ms and more frequently from 500 to 600 ms after the R-wave, compared to worst shots. In the exercise condition, best shots were fired less frequently from 100 to 200 ms after the R-wave and from 20% to 30% of the R-R interval, compared to worst shots. These findings support the hypothesis that shooting accuracy is influenced by the cardiac cycle phase due to the ballistocardiac recoil generated at each heartbeat. To achieve best results athletes could be trained (e.g. through biofeedback) to fire within a specific phase of the cardiac cycle.
