Country line dancing (CLD) is a popular activity among older women. The American College of Sports Medicine and Health Canada recommend that aerobic exercise be performed for 20–60 min, 3–5 times/week, at an intensity of 65–90% of maximal heart rate (HR). The study measured responses to a bout of CLD in older women to determine whether it might be considered an aerobic activity for this population. Twenty healthy older women performed a 12-min walk lest (12WT) and a 1-hr CLD class. Heart rate and ratings of perceived exertion (RPE) and breathlessness (RPB) were compared between the 12WT and a representative 12-min period of the CLD class. Mean HR during CLD and the 12WT were not different. Mean RPE and RPB values were also similar between CLD and 12WT. The results suggest that CLD meets the guidelines for aerobic activity and can be considered an acceptable form of aerobic exercise for older women.

Affect Heart Rate

This study assessed the effects of associative and dissociative psychological strategies of attention on heart rate and self-report ratings of perceived exertion (RPE) during cycling performance. Seven trained cyclists performed a control ride, a dissociation ride, and an association ride on a bicycle ergometer at a work rate corresponding to 75% of their maximal heart rate. For the dissociation ride, subjects watched a videotape unrelated to cycling and responded to a key word each time it occurred on tape. For the association ride, subjects focused attention on heart-rate feedback available throughout the ride. During the control ride, attentional focus was not intentionally manipulated. Analysis indicated that the deliberate application of an attentional strategy did not significantly affect heart rate or RPE scores; however, the dissociation condition yielded somewhat higher RPE scores. From a postexperimental interview, four subjects responded that the association ride was the easier to complete, while three subjects responded the control ride was the easier one, matching a possible trend in the data.

Main Effects

Ratings of perceived exertion (RPE) and their relation to selected physiological mediators during endurance exercise have been limited to laboratory settings. The present study characterized the pattern of change in perceptual responses and examined the relation between RPE and selected physiological variables during a long competitive sporting event, i.e., an ultramarathon race (68 km). A single-group design was employed in which all of the 28 subjects provided their perceptual ratings (11.9 ± 0.2) and heart rate (HR) (138 ± 3) periodically (every 5 km) throughout the ultramarathon, and selected physiological responses were measured before, once during (32 km), and immediately after the race. Runners drank approximately 1,000 ml of carbohydrate beverage each hour (60 gm carbohydrate hr.−1) and ate 2 or 3 carbohydrate gel packs per hour (25 gm each−1). RPE increased significantly throughout the course of the ultramarathon. No significant correlations were found between RPE and HR at any time throughout the ultramarathon. RPE averaged 10.4 ± 0.4 at the beginning of the race (6.4 km) and 15.4 ± 0.4 at the conclusion of the race. Subjects maintained 76.9 ± 1.1% of maximal heart rate; however, there was a tendency for heart rate to drop significantly after 32 km. Significant time main effects were found for serum glucose, insulin, and cortisol throughout the race. However, no significant correlations were found between RPE and any of these physiological mediators. These data indicate that during an ultramarathon race there is a progressive increase in RPE without an accompanying increase in HR or decrease in blood glucose. Therefore, during competitive self-paced exercise the perceptual responses may be mediated through other neurological and physiological mechanisms.

Passive Recovery

The purpose of the study was to investigate the effects of passive recovery with self-selected time on affect, ratings of perceived exertion, and heart rate in self-selected interval exercises (SSIE). Fifteen older women (68.1 ± 3.8 years), weekly practitioners of functional activities participated in three SSIE with self-selected recovery time (SSRT) and one self-selected continuous exercise session, all at 24 min approximately. The SSIE had the following configurations: 1′/SSRT, 1.5′/SSRT, and 2′/SSRT. The results showed that at the beginning of stimulus heart rate in 1.5′/SSRT (107.9 ± 16.5) and 2′/SSRT (114.6 ± 17.1) were significantly greater (p < .05) compared with self-selected continuous exercise (102.8 ± 14.5). The ratings of perceived exertion in self-selected continuous exercise (2.4 ± 0.4; p < .05) were higher compared with SSIE in recovery. No significant differences were found in affect. The SSIE provided similar responses based on recoveries manipulations.

Walking Test

The study investigated physiological responses during 2-km walking at a certain intensity of a previously performed maximal exercise test where moderate perceived exertion was reported. Twenty seniors were examined by an incremental walking treadmill test to obtain maximal oxygen uptake (VO2max). A submaximal 2-km walking test was applied 1 wk later. The corresponding moderate perceived exertion (4 on the CR-10 scale) during the VO2maxtest was applied to the 2-km treadmill test. Moderate exertion (mean rating of perceived exertion [RPE]: 4 ± 1) led to 76% ± 8% of VO2maxand 79% ± 6% of maximal heart rate. RPE values drifted with a significant time effect (p= .001, ηp= .58) during the 2-km test from 3 ± 0.7 to 4.6 ± 0.8. Total energy expenditure (EE) was 3.3 ± 0.5 kcal/kg. No gender differences in ventilatory, heart-rate, or EE data occurred. Brisk walking at moderate RPE of 3–5 would lead to a beneficial physiological response during endurance training and a weekly EE of nearly 1,200 kcal when exercising 5 times/wk for 30 min.

AIM: There is some evidence to suggest that exercise in the evening, compared with exercise in the morning, has a more beneficial impact on glycemia in patients with type 2 diabetes (T2D). The aim of this study was to examine a possible acute effect of aerobic exercise performed at different times of day on blood glucose levels during and after exercise in patients with T2D. MATERIAL & METHOD: Eight male T2D patients (61.8 ± 6.9 yrs, 27.7 ± 3.1 kg/m2, HbA1c: 6.5 ± 1.1%; mean ± SD), who did not receive insulin, performed 60-min cycling at about 75% maximal heart rate (HRmax) either at 10:30 (Morning-M), or at 17:30 (Evening-E), or 30-min cycling at 10:30 and 30-min cycling at 17:30 (ME). A control condition (C) was also included where volunteers did not exercise but had their blood glucose measured at day-time intervals similar to the time intervals of the three exercise trials. Two days before each condition no physical activity was allowed, while the day before and on the day of each trial participants controlled their diet. RESULTS: Compared to resting levels, blood glucose at the end of exercise decreased at similar levels in M (20 ± 12%), E (28 ± 14%), in the morning of ME (21 ± 10%) and in the evening of ME (26 ± 19%) (p > 0.05). Also, heart rate, blood lactate and rate of perceived exertion responses during exercise were similar between the 3 exercise conditions. Mean area under the blood glucose-time curve over the two-hour post-exercise period in exercise trials, and at similar time intervals in C, was different only between the morning in C (15,173 ± 1830 mg/dL•120 min) and the evening in ME (11,681 ± 1526 mg/dL•120 min, p = 0.045). In addition, overnight fasting serum glucose the morning after each trial was similar between conditions (p > 0.05). CONCLUSIONS: No acute effect of cycling at about 75% HRmax was observed on glycemia in patients with T2D when exercise was performed at different times of day.

Trial Performance

The primary purpose of this study was to determine the reproducibility of the 6-min-walk test (6MWT) in older women. A secondary purpose was to document heart rate (HR), blood pressure (BP), and ratings of perceived exertion (RPE) in response to the 6MWT. Twenty-eight women with an average age of 80.0 years (±5.2) participated. They performed 2 trials of the 6MWT on 3 separate days, for a total of 6 trials. Heart rate, BP, RPE, and the total distance walked were recorded for each trial. The results indicated a significant increase from Trial 1 to Trial 2, with no differences between Trials 2–6, F(5, 131) = 7.02, p = .000. HR and BP were consistent across the 6 trials, and RPE was higher for the second trial on the second day of testing, F(5, 131) = 2.72, p = .023. The intraclass correlation coefficient for distance walked was .94. After the initial trial, performance on the 6MWT appears to be stable in older women.

Squat Lifting

A comparison between semi-squat and squat techniques was made for floor to knuckle height lifting using maximum acceptable weight (MAW), ratings of perceived exertion (RPE) and heart rate. Semi-squat lifting resulted in greater MAW with lower RPE and lower heart rate compared to squat lifting. Discomfort was most commonly reported in knees/quadriceps with squat lifting. Twelve of the 13 subjects preferred the semi-squat technique. The results provide evidence that the semi-squat technique may have benefits over the squat technique for lifting a medium sized box from floor to knuckle height.
