To investigate the strength of the relationship between ratings of perceived exertion (RPE) and oxygen uptake (Vo(2)), heart rate, ventilation (Ve) and power output (PO) during an arm-crank ramped exercise test to volitional exhaustion in men and women who differed in physical status.
Each participant completed an arm-crank ramp exercise test to volitional exhaustion. PO was increased by 15 W.min(-1) and 6 W.min(-1) for men and women able-bodied participants, respectively; for the poliomyelitis participants, 9 W.min(-1) and 6 W.min(-1) increments were used for men and women, respectively.
Laboratory facilities at a university.
Able-bodied participants (n=16; 9 men, 7 women) and participants with poliomyelitis (n=15, 8 men, 7 women) volunteered for the study.
Strength of the relationship (R(2) values) between RPE and Vo(2), heart rate, Ve and PO.
There were significantly higher values for maximum Vo(2) and maximum PO for able-bodied men compared with their counterparts with poliomyelitis (P<.05). However, when the data were controlled for age, there were no significant differences in these values (P>.05). Similar results were observed for the women who were able-bodied as well as for the women who had poliomyelitis (P>.05). The relationships between heart rate and RPE and Ve and RPE for able-bodied patients and patients with poliomyelitis were similar (R(2)>.87). The relationship between Vo(2) and RPE was stronger in the able-bodied participants compared wih the participants with poliomyelitis, regardless of sex (P<.05). However, when the data were controlled for age, there was no significant difference in the strength of this relationship between able-bodied participants and those with poliomyelitis, regardless of sex (P>.05).
RPE is strongly related to physiologic markers of exercise intensity during arm exercise, irrespective of sex or participant's poliomyelitis status.
研究在男性和女性体力状况不同的情况下，手臂曲柄递增负荷至力竭运动试验中，感觉用力程度（RPE）与摄氧量（Vo(2)）、心率、通气量（Ve）和功率输出（PO）之间的关系强度。
每位参与者都完成了手臂曲柄递增负荷至力竭运动试验。对于健康的男性和女性参与者，Po 分别以 15 W.min(-1)和 6 W.min(-1)增加；对于脊髓灰质炎参与者，男性和女性分别使用 9 W.min(-1)和 6 W.min(-1)的增量。
大学的实验室设施。
健康的参与者（n=16；9 名男性，7 名女性）和患有脊髓灰质炎的参与者（n=15，8 名男性，7 名女性）自愿参加了这项研究。
RPE 与 Vo(2)、心率、Ve 和 PO 之间关系的强度（R(2)值）。
与患有脊髓灰质炎的对应者相比，健康男性的最大 Vo(2)和最大 PO 值明显更高（P<.05）。然而，当数据根据年龄进行控制时，这些值没有显著差异（P>.05）。健康的女性以及患有脊髓灰质炎的女性也观察到了类似的结果（P>.05）。健康患者和脊髓灰质炎患者的心率与 RPE 以及 Ve 与 RPE 之间的关系相似（R(2)>.87）。与脊髓灰质炎患者相比，健康参与者 Vo(2)与 RPE 之间的关系更强，无论性别如何（P<.05）。然而，当根据年龄控制数据时，无论性别如何，健康参与者和脊髓灰质炎参与者之间这种关系的强度都没有显著差异（P>.05）。
无论性别或参与者的脊髓灰质炎状况如何，RPE 与手臂运动时运动强度的生理标志物密切相关。
