EFFECT OF RESISTANCE TRAINING ON PHYSICAL PERFORMANCE AND FUNCTIONAL RESPIRATORY CAPACITY OF ELDERLY WOMEN

ABSTRACT In the aging process, additionally to other functional losses, there are reductions in physical and functional respiratory performance.It is known that resistance training (RT) is effective at developing trophism and muscle strength; however, little is known about the influence of RT on respiratory variables. To compare maximal inspiratory and expiratory pressures (MIP; MEP), Axillary, Xiphoid and Abdominal ranges - AxR, XiR and AbR -, Peakflow and performance in theIncremental Shuttle Walk Test (ISWT) of elderly women participating in an RT program with those of untrained ones. Methods: 53 women, aged 66 ± 5.2 years -28 participants of an extension project at Pará State University, with a minimum of 6 months of practice in a RT program, composing the trained group (TG), and 25 volunteers who composed the untrained group (UG). Assessments consisted of measurements of MIP, MEP, AxR, XiR, AbR, Peak Flow and performance in the ISWT. As results, significant differences were found, with better values in the TG as to all variables assessed, except for AbR. In conclusion, elderly women subjected to anRT program showed favorable and significant differences in MIP, MEP, XiR, Peakflow and ISWT compared tountrained ones.

摘要：在衰老进程中，除其他功能衰退外，躯体与呼吸功能表现亦会出现下降。已知抗阻训练（resistance training, RT）可有效促进肌容积增长与肌力提升，但目前人们对其影响呼吸相关指标的效果仍了解甚少。本研究旨在比较参与抗阻训练计划的老年女性与未受训老年女性的最大吸气压（maximal inspiratory pressure, MIP）、最大呼气压（maximal expiratory pressure, MEP）、腋中线活动度（Axillary range, AxR）、剑突下活动度（Xiphoid range, XiR）、腹部活动度（Abdominal range, AbR）、峰流速（Peakflow）及增量穿梭步行试验（Incremental Shuttle Walk Test, ISWT）表现。方法：本研究共纳入53名年龄为66±5.2岁的女性受试者，其中28名来自帕拉州立大学推广项目，均已坚持至少6个月的抗阻训练计划，构成训练组（TG）；剩余25名志愿者构成未训练组（UG）。评估内容包括MIP、MEP、AxR、XiR、AbR、峰流速及ISWT表现的测量。结果：两组受试者在所有评估指标上均存在显著差异，训练组的各项指标表现均优于未训练组，仅腹部活动度除外。结论：与未受训老年女性相比，参与抗阻训练计划的老年女性在MIP、MEP、XiR、峰流速及ISWT表现上均呈现出更优且具有统计学意义的差异。
