“…In addition, there was no signi®cant relationship between peak D _ V I and peak BP during voluntary exercise and passive movement in either group. These results suggest that control of the blood pressure response is dierent from that of ventilatory and f c responses at the onset of exercise as has been suggested by Fontana et al (1993) andNoÂ brega et al (1995). In this study, the BP in the children was increased a little or remained close to the rest value, while it was signi®cantly decreased in the adults during both voluntary exercise and passive movement.…”

The purpose of this study was to investigate whether or not the ventilatory and circulatory responses at the onset of voluntary exercise and passive movement, especially at the initial stage (phase I), in children are the same as in adults. Ten pre-teenage male children and ten adult men participated in this study. Voluntary exercise and passive movement were performed in a sitting position for about 20 s. Both the exercise and the movement consisted of flexion-extensions of the lower leg from a vertical to horizontal position, either voluntarily or passively, with a frequency of about 60 x min(-1). Inspiratory minute ventilation (V1), tidal volume (VT), respiratory frequency, partial pressure of end-tidal CO2 and O2, heart rate (fc) and mean blood pressure (BP) before, during and after exercise or movement were measured using breath-by-breath and beat-to-beat techniques. Cardiorespiratory responses at the onset of voluntary exercise and passive movement were compared with the relative change (delta), which was estimated from the value at rest (100%). In the present study, it was found that: (1) the V1 during voluntary exercise were significantly lower in the children, mainly due to lower deltaVT; (2) the delta(f)c during voluntary exercise was almost the same in both groups, while deltaf(c) was significantly lower in the children during the last part of passive movement; (3) in the voluntary exercise and passive movement, the BP in the children was increased a little or remained close to the value at rest, while it was significantly decreased in the adults. As a result, there were significant differences in deltaBP between the two groups during voluntary exercise. These results suggest that the cardiorespiratory responses at the onset of voluntary exercise and passive movement may be modified during the growth process.

“…6, significant correlations between aDV _ I and aDHR during brief voluntary exercise were recognized both in women (r=0.92, P<0.01) and in men (r=0.82, P<0.05), but not during brief passive movement. Fontana et al (1993) observed significant positive correlations between the increase in V _ I and that in HR during the final 30 s of 3 min of static handgrip exercises at 25% and 30% MVC but not at 15% MVC. Their study and the present study demonstrate that a relationship like this is observed not only during static exercise for a few minutes but also at the onset of voluntary exercise and that it is not recognized unless exercise over a certain intensity is performed.…”

“…We have no information to explain this point. Nevertheless, Fontana et al (1993) suggest that the relationship between ventilatory response and HR response is caused by a considerable degree of coordination and integration of respiratory and cardiovascular functions at a central level, despite the possibility of a differential control. If so, it would be possible that this coordination and integration of respiratory and circulatory centers occurred to the same extent in women and men.…”

To clarify the luteal-follicular and male-female differences in ventilatory and heart rate responses at the onset of exercise, seven women and seven men performed voluntary exercise and passive movement for 20 s (brief voluntary exercise and brief passive movement) and voluntary exercise for 3 min (long voluntary exercise) in a sitting position. Voluntary exercise consisted of alternate flexion-extensions of both lower legs with a weight corresponding to about 2.5% of the subjects' body mass attached to each ankle, at a frequency of about 60 times min(-1). Passive movement was carried out without weights by experimenters pulling ropes attached to both of the subjects' ankles, in the same way as voluntary exercise. During these exercises and movements, minute inspiratory ventilation ( V(I)) and heart rate (HR) were continuously measured by breath-by-breath and beat-to-beat techniques. We calculated relative changes of V(I) and HR (Delta V(I) and DeltaHR). Additionally, we averaged Delta V(I) and DeltaHR obtained during the exercise and movement for each subject, and performed a correlation analysis between the averaged Delta V(I) and DeltaHR. It was clarified that: (1) Delta V(I) and DeltaHR in the follicular phase were almost equal to those in the luteal phase; (2) there were no significant male-female differences in these parameters; (3) significant positive correlations were found in both genders only during brief voluntary exercise. We conclude that ventilatory and HR responses at the onset of voluntary exercise and passive movement are not affected by the menstrual cycle or gender.

In occupational work, continuous repetitive and isometric actions performed with the upper extremity primarily cause local muscle strain and musculoskeletal disorders. They may also have some adverse effects on the cardiorespiratory system, particularly, through the elevation of blood pressure. The aim of the present study was to compare peak cardiorespiratory responses to fatiguing dynamic and isometric hand-grip exercise. The subjects were 21 untrained healthy men aged 24-45 years. The dynamic hand-grip exercise (DHGE) was performed using the left hand-grip muscles at the 57 (SD 4)% level of each individual's maximal voluntary contraction (MVC) with a frequency of 51 (SD 4) grips x min(-1). The isometric hand-grip exercise (IHGE) was done using the right hand at 46 (SD 3)% of the MVC. The endurance time, ventilatory gas exchange, heart rate (HR) and blood pressure were measured during both kinds of exercise. The mean endurance times for DHGE and IHGE were different, 170 (SD 62) and 99 (SD 27) s, respectively (P < 0.001). During DHGE the mean peak values of the breathing frequency [20 (SD 6) breaths x min(-1)] and tidal volume [0.89 (SD 0.34) l] differed significantly (P < 0.01) from peak values obtained during IHGE [15 (SD 5) breaths x min(-1) and 1.14 (SD 0.32) l, respectively]. The corresponding peak oxygen consumptions, pulmonary ventilations, HR and systolic blood pressures did not differ, and were 0.51 (SD 0.06) and 0.46 (SD 0.11) l x min(-1), 17.1 (SD 3.0) and 16.7 (SD 4.7) l x min(-1), 103 (SD 18) and 102 (SD 17) beats x min(-1), and 156 (SD 17) and 161 (SD 17) mmHg, respectively. The endurance times of both DHGE and IHGE were short (< 240 s). The results indicate that the peak responses for the ventilatory gas exchange, HR and blood pressure were similar during fatiguing DHGE and IHGE, whereas the breathing patterns differed significantly between the two types of exercise. The present findings emphasize the importance of following ergonomic design principles in occupational settings which aim to reduce the output of force, particularly in tasks requiring isometric and/or one-sided repetitive muscle actions.
