Natural physique competitions are based on subjective judgments of how a competitor appears on show day. Prior to competition, there is a prolonged dieting phase referred to as contest preparation. The primary goal is to reduce body fat levels while maintaining skeletal muscle mass. The study tracked the physiological and psychological changes for a 24 year old female preparing for a physique competition.
The study was conducted to describe the physiological and psychological changes of a female physique competitor who engages in long-term contest preparation.
Diet, body composition, blood work, energy expenditure, mood, and performance were evaluated through contest preparation.
The participant lost 10.1kg throughout contest preparation in a strong weekly linear pattern (R=0.97). Body fat was reduced from 30.45% to 15.85% while fat free mass was maintained. Mood for the participant remained stable until month five, when an observed variation occurred, with performance maintaining.
Contest preparation was successful in reducing the body fat in the participant while having a minimum effect on both performance and fat free mass. For athletes looking to lose large amounts of body fat with minimal performance decrements a prolonged diet period with moderate exercise and food restriction can be an effective solution.
自然体型竞赛基于对参赛者在比赛日外观的主观评判。在比赛前，有一个被称为备赛的长期节食阶段。主要目标是在保持骨骼肌质量的同时降低体脂水平。该研究追踪了一名准备参加体型竞赛的24岁女性的生理和心理变化。
进行该研究以描述一名长期进行备赛的女性体型参赛者的生理和心理变化。
通过备赛过程评估饮食、身体成分、血液检查、能量消耗、情绪和表现。
在整个备赛过程中，参与者以强劲的每周线性模式减重10.1千克（R = 0.97）。体脂从30.45%降至15.85%，同时无脂肪体重保持不变。参与者的情绪在第五个月前保持稳定，此时出现了观察到的变化，而表现保持稳定。
备赛成功降低了参与者的体脂，同时对表现和无脂肪体重的影响最小。对于希望在最小程度降低表现的情况下大量减少体脂的运动员来说，长时间的节食期结合适度运动和食物限制可能是一种有效的解决方案。
