The aim of the present study was to examine self-reported psychological states and physiological responses (heart rate) experienced during different motivational general imagery scenarios. Forty competitive athletes wore a standard heart rate monitor and imaged five scripts (mastery, coping, anxiety, psyching up, and relaxation). Following each script, they reported their state anxiety and self-confidence. A significant increase in heart rate from baseline to imagery was found for the anxiety, psyching-up, and coping imagery scripts. Furthermore, the intensity of cognitive and somatic anxiety was greater and perceived as being more debilitative following the anxiety imagery script. The findings support Lang’s (1977, 1979) proposal that images containing response propositions will produce a physiological response (i.e., increase heart rate). Moreover, coping imagery enabled the athletes to simultaneously experience elevated levels of anxiety intensity and thoughts and feelings they perceived as helpful.

The purpose of this study was to assess the difference in maximal physiological responses between an acute bout of deep-water running (DWR) and treadmill running (TMR) in young and older adults. Participants were 9 young and 9 older women who performed maximal DWR and TMR tests. Maximal measures included oxygen consumption (VO2max), heart rate (HRmax), ventilation (VE), respiratory-exchange ratio (RER), and blood lactate (BLac). The young women exhibited higher VO2max, HRmax, VE, and BLac than did the older women for both exercise conditions (p < .05). Lower VO2max and HRmax values were observed with DWR for both age groups (p < .05). No significant differences were found for VE, RER, and BLac in either group between exercise conditions, nor a significant interaction between exercise conditions or ages for any of the variables measured. The data suggest that although older adults exhibit lower maximal metabolic responses, differences between DWR and TMR responses occur irrespective of age.

Chronic effects of two different exercise environments on self-chosen intensity and physiological adaptations were examined in postmenopausal women. Twenty-three healthy to overweight (body mass index [BMI] 22–29 kg/m2) postmenopausal women performed three weekly training sessions during 12 weeks and were assigned to either: (1) indoor training or (2) outdoor training. Body composition, metabolic profile, and physical fitness (including Vo2max, maximal strength, and endurance) were assessed pre- and postintervention. Exercise intensity was measured every week during the training. Maximum intensity decreased significantly in time only in outdoor training (p ≤ .05). Body composition and VO2max were significantly improved indoors (p ≤ .05), whereas resting blood pressure and upper body maximal strength and endurance were improved outdoors (p ≤ .05). Indoor training is associated with maintaining intensity over time and slightly higher physiological improvements than outdoor training. However, outdoor training seems promising from a long-term perspective, due to its positive effects on health parameters and exercise adherence.

This paper discusses the delivery of sport psychology services to physically challenged (disabled) athletes. It begins with a description of the current status of athletic competition for physically disabled individuals. Commonalities in the sports experience of able-bodied and physically disabled athletes are addressed. Unique issues that must be considered for effective sport psychology consultations with disabled athletes are discussed. These include the background of physical and psychological trauma, altered physiological responses and medical problems, complexities in motivation to compete, unique performance problems, and the structure and organization of disabled sports. The article concludes with the effects of the social environment of disabled sports on the consultation process.

The purpose of this study was to investigate the effects of moral identity on physiological responses to affective pictures, namely, the startle blink reflex and pain-related evoked potential. Male (n = 48) and female (n = 46) athletes participating in contact team sports were randomly assigned to either a moral identity group or a non-moral identity group and viewed a series of unpleasant, neutral, and pleasant sport-specific pictures. During picture viewing, a noxious electrocutaneous stimulus was delivered as the startle probe and the startle blink and pain-related evoked potential were measured. Upon completion of physiological measures, participants reviewed the pictures and rated them for valence and arousal. ANOVAs revealed that participants in the moral identity group displayed larger startle blinks and smaller pain-related potentials than did those in the non-moral identity group across all picture valence categories. However, the difference in the magnitude of startle blinks between the moral and non-moral identity groups was larger in response to unpleasant than pleasant and neutral pictures. Our findings suggest that moral identity affects physiological responses to sport-specific affective pictures, thereby providing objective evidence for the link between moral identity and emotion in athletes.

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 VO2max test was applied to the 2-km treadmill test. Moderate exertion (mean rating of perceived exertion [RPE]: 4 ± 1) led to 76% ± 8% of VO2max and 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.
