Stress is a psychophysical condition that causes an impairment in athletes’ performance by causing an increase in sympathetic activity and an autonomic imbalance. The current methods for the measurement of psychophysiological stress introduce the use of the heart rate variability as a useful index of the well-being of these people. The heart rate variability corresponds to the time intervals between consecutive heartbeats, such as an irregularity in the normal sinus heart rhythm whose variability is due to the control exercised by a complex system of mechanisms, including the respiratory control system, and provides information about the activity of the sympathetic and parasympathetic branches of the autonomic nervous system. This review aims at summarizing the promising results, despite small amount, of the recent literature on the efficacy of heart rate variability biofeedback on the autonomic imbalance and psychophysical well-being of athletes as well as cognitive and motor performance.

Instructors in organized physical activity classes can be a source of social support through their relationships with participants, influence on participants’ interactions with each other, and design of activities. Grounded in interpretive description, the objective of this study was to examine older adults’ experiences of and their perspectives on group physical activity instructors’ supportive behaviors. Observations of 16 group physical activity classes (N = 295) and focus groups or interviews with N = 38 class participants aged ≥ 55 (n = 29 women) were conducted at four municipal recreation facilities in a Canadian city. Five themes shed light on how instructors provided social support: (a) supporting autonomous engagement, (b) developing caring connections, (c) fostering trust through expert instruction, (d) managing conflict directly and effectively, and (e) creating a climate where people want to go. Instructor training should consider older adults’ social support needs and help instructors embody behaviors that support continued physical activity participation, thereby contributing to healthy aging.

While masters sport aligns with the holistic concept of active aging, related research has focused predominantly on the physical domain, and less is known about the psychological, cognitive, and social benefits of older adults’ participation. This study examined, in combination, the perceived psychological, social, cognitive, and physical benefits of training and competing as a masters athlete, while considering age and gender differences. Forty masters athletes residing in Canada were interviewed (21 men and 19 women; 15 who were 50–64 years and 25 who were 65–79 years), representing 15 different sports. Interviews were coded both deductively and inductively, revealing several subthemes of benefits for the broader perceived psychological, social, cognitive, and physical benefits, with few but notable differences between women and men, and those younger than 65 years and those 65+ years. Our findings provide new insights into the positive experiences of active aging associated with high levels of physical activity among older adults, such as greater self-confidence, especially for women, comradery, and feeling mentally sharper, especially for the older age group.

Although dance interventions may have lots of advantages in improving frailty, there are few papers focusing on the effects such interventions have on frail older adults living in the community setting. This study investigates whether a dance intervention can improve the level of frailty among Chinese older adults living in the community setting. The dance intervention was done five times a week for 16 weeks. Participants in the control group maintained their normal daily activities. Assessments were conducted at baseline, 8 weeks, and 16 weeks. Mixed models were used to test for the effects on frailty, depression, short physical performance battery, and grip strength between the groups over time. The level of frailty (p < .05) and depression (p < .001) decreased, and short physical performance battery (p < .001) increased over time in the dance group compared with the control group. A dance intervention lasting 16 weeks showed improved frailty, depression, and physical performance among Chinese older adults living in the community setting.

Online exercise programming has surged in popularity; however, little is known about older adults’ perceptions and experiences of online exercise. The purpose of this study was to qualitatively examine older adults’ (aged 59–82 years) experiences and perceptions of an online exercise program during the COVID-19 pandemic. Nineteen individuals (individuals who used the online exercise program and those who did not) completed a semistructured interview. Three main themes were generated from the data using reflexive thematic analysis: (a) can online exercise really work for older adults? (b) technology attitudes and experiences influence online participation, and (c) barriers and advantages of the online exercise program and the home environment. Most participants who took part were able to overcome initial barriers through technical support and experience. Our findings highlight ways to promote advantages and address barriers of online exercise for older adults and emphasize the importance of fostering social experiences and training online exercise instructors.

To investigate the association between physical activity (PA) domains and chronic low back pain (LBP) in older adults. A cross-sectional study where sociodemographic, behavioral, and health variables; PA; and presence of chronic LBP were collected. Higher scores of PA defined the “more active” participants. Binary logistic regression was used to test the association between PA domains and chronic LBP. A total of 516 participants were included. The mean age was 71.8 (95% confidence interval, CI, [71.1, 72.5]) years, and 29%, 27%, 25%, and 31% were identified as “more active” in the household, sports, leisure-time, and total PA domains, respectively. “More active” participants in sports (odds ratio = 0.62, 95% CI [0.40, 0.97]), leisure-time (odds ratio = 0.54, 95% CI [0.35, 0.85]) and total (odds ratio = 0.60, 95% CI [0.39, 0.92]) PA domains were less likely to report chronic LBP. High levels of sports, leisure-time, and total PA were inversely associated with chronic LBP.

For decades, the exercise psychology research literature echoed the conclusion that exercise makes most people feel better, with no clear evidence that this “feel-better effect” is moderated by intensity. An overhaul of the methodological approach subsequently showed that high-intensity exercise is experienced as unpleasant, and the “feel-better effect,” although possible, is conditional and therefore not as robust or prevalent as initially thought. Recently, several studies investigating high-intensity interval training (HIIT) have concluded that HIIT is pleasant and enjoyable, despite the high intensity. Considering that HIIT is emerging as an option in physical activity recommendations and exercise prescription guidelines, in part due to these claims, a methodological checklist is presented to aid researchers, peer reviewers, editors, and other readers in critically appraising studies examining the effects of HIIT on affect and enjoyment. This first part addresses the characteristics and number of participants, as well as the selection of measures of affect and enjoyment.
