"研究者想根据一些变量(age、weight、heart_rate和gender)预测另一个变量(VO2 max)。针对这种情况,可以使用多重线性回归分析,但需要先满足以下8项假设:" 请问多重线性回归分析需满足的条件中没有像logistic回归那样对纳入自变量个数与样本量的要求,意思是没有这个条件限制?如果有,请问一般是每个自变量至少对应多少...

If you have a faster-than-normal heart rate (your heart beats more than 100 times per minute), you have what doctors call tachycardia. It’s not always a bad thing. Exercise, for example, can push your heart rate above 100 bpm. However, you may require medication to slow your heart r...
This study examines heart rate (HR) and perceived experience during same- versus mixed-gender soccer played as small- (SSG) and large-sided (LSG) games. HR, rating of perceived exertion (RPE), and fun scores were determined in 134 pupils (50 girls, 84 boys) randomly assigned to same- ...
Considerable research links chronic pain to autonomic nervous system (ANS) dysfunction, specifically low heart rate variability (HRV) mediated by reduced parasympathetic activity. However, little is known about factors that influence ANS function in chronic pain. The ANS is the primary pathway for brai...
HRV = heart rate variability; other abbreviations as in Table 1. 3.3. HRV: Gender Differences Previous investigations have found gender differences in 24-h HRV, with values for female subjects being significantly lower than those for age-matched male subjects 15, 19, 21. In this regard, Hoogen...
Theheart valvesdetermine the flow of blood through the heart. The valves open and close to allow for unidirectional blood flow, preventing regurgitation or blood flow in the wrong direction. Valves are classified as atrioventricular (AV) or semilunar. The two AV valves, themitral valveand thetric...
Purpose: The purpose of this study was to identify the relation of Job Stress, Heart Rate Variability, Blood Pressure and Lifestyle on White-Collar Workers. Method: Data were collected from August to December in 2007. HRV was measured using Freeze-Framer. WSRI and Lifestyle data were collecte...
The repeated measurements of heart rate variability (HRV) is more relevant than a single HRV measurement in predicting patient prognosis but is less addressed previously. This prospective study aimed to investigate the association between repeated measurements of HRV and long-term mortality in chronic ...
Reports of previous studies have described significant gender differences in blood pressure responses to diltiazem in healthy volunteers tested with the same protocol. In contrast to the data in healthy individuals, gender differences in blood pressure responses to exercise before and after diltiazem ...
