<p>The present study analyzes individual and group heart rate responses in exercising adult women. The specific aim was to compare responses during routine workout sessions within a community exercise program with responses during a purpose-designed workout session targeting diverse motor skills. Sixty-seven adult women with a mean ± SD age of 65.1 ± 11.7 years participated in the study. Two representative sessions were analyzed: a standard workout session the women took at the local community center and an <em>ad hoc </em>session designed to build on a variety of motor skills and capabilities. Observational methodology was used to collect categorical data on motor skill performance during each session using the OSMOS-in context observation instrument. Continuous heart rate data were recorded for all participants during each session. A combined analysis of categorical and continuous data was undertaken using Hidden Markov Models. The results show that the session targeting a greater diversity of motor skills not only met the cardiovascular fitness recommendations of the American College of Sports Medicine, but resulted in greater individual variability and greater synchrony between participants than the routine session.</p>

Objective assessments of concussion recovery are crucial for facilitating effective clinical management. However, predictive tools for determining adolescent concussion outcomes are currently limited. Research suggests that heart rate variability (HRV) represents an indirect and objective marker of central and peripheral nervous system integration. Therefore, it may effectively identify underlying deficits and reliably predict the symptomology following concussion. Thus, the present study sought to evaluate the relationship between HRV and adolescent concussion outcomes. Furthermore, we sought to examine its predictive value for assessing outcomes. Fifty-five concussed adolescents (12–17 years old) recruited from a local sports medicine clinic were assessed during the initial subacute evaluation (within 15 days postinjury) and instructed to follow up for a post-acute evaluation. Self-reported clinical and depressive symptoms, neurobehavioral function, and cognitive performance were collected at each timepoint. Short-term HRV metrics via photoplethysmography were obtained under resting conditions and physiological stress. Regression analyses demonstrated significant associations between HRV metrics, clinical symptoms, neurobehavioral function, and cognitive performance at the subacute evaluation. Importantly, the analyses illustrated that subacute HRV metrics significantly predicted diminished post-acute neurobehavioral function and cognitive performance. These findings indicate that subacute HRV metrics may serve as a viable predictive biomarker for identifying underlying neurological dysfunction following concussion and predict late cognitive outcomes.

Objective : To investigate the effectiveness of workplace exercise for employee health by means of health-related physical activity components. Methods : A randomized uncontrolled study with 20 workers was carried out during three months to evaluate a workplace exercise program. The selected outcomes were flexibility, body mass, fat percentage, lean mass, blood pressure, and heart rate. For statistical analysis, the paired t test and the intent-to-treat analysis were used. Results : There was a significant increase in weight, fat percentage, blood pressure, and heart rate. However the clinical significance was 10% in the size of the effect. Conclusion : The changes verified in the outcomes analyzed were not significant; the variables are within normality ranges proposed by academic organizations

Advantages And Disadvantages

ABSTRACT Exercise prescription is complex and can vary greatly. As well, methods have their own advantages and disadvantages. The purpose of this discussion is to consider if some of these methods should be modified. We look at the concept of the heart rate and oxygen intake reserve because it is recommended by the American College of Sports Medicine.

The aim of this study was to analyze blood lactate concentration (LAC), heart rate (HR), and rating perceived exertion (RPE) during and after shorter and longer duration CrossFit® sessions. Nine men (27.7 ± 3.2 years; 11.3 ± 4.6% body fat percentage and training experience: 41.1 ± 19.6 months) randomly performed two CrossFit® sessions (shorter: ~4 min and longer: 17 min) with a 7-day interval between them. The response of LAC and HR were measured pre, during, immediately after, and 10, 20, and 30 min after the sessions. RPE was measured pre and immediately after sessions. Lactate levels were higher during the recovery of the shorter session as compared with the longer session (shorter: 15.9 ± 2.2 mmol/L/min, longer: 12.6 ± 2.6 mmol/L/min; p = 0.019). There were no significant differences between protocols on HR during (shorter: 176 ± 6 bpm or 91 ± 4% HRmax, longer: 174 ± 3 bpm or 90 ± 3% HRmax, p = 0.387). The LAC was significantly higher throughout the recovery period for both training sessions as compared to pre-exercise. The RPE was increased immediately after both sessions as compared to pre-exercise, while there was no significant difference between them (shorter: 8.7 ± 0.9, longer: 9.6 ± 0.5; p = 0.360). These results demonstrated that both shorter and longer sessions induced elevated cardiovascular responses which met the recommendations for gains in cardiovascular fitness. In addition, both training sessions had a high metabolic and perceptual response, which may not be suitable if performed on consecutive days.

The Impact

The National Department of Health invited comments on proposed policy guidelines on the prevention of physical inactivity in older persons at primary level. The guidelines recommended the use of exercises which are dynamic, interesting, fun, easily implemented, safe and tailored to suit the individual needs. In order to make informed comments on the policy, the aim of this study was to evaluate the impact of the recommended exercise program among older persons in a local community over a six-week period. Promoting physical activity among the participants in the study resulted in marked improvements in systolic and diastolic blood pressures, and dominant hand grip strength. The time taken to perform some selected functional tasks also improved. The findings gave credence to the need to discourage physical inactivity among older persons, but there is need to overcome formidable methodological problems in evaluating the effects of exercise intervention among older persons in the community.

SOCIALIZATION AND EDUCATION ON THE UTILIZATION OF BANANA SKIN WASTE AS ANTIOXIDANT-RICH NATURAL FACE MASKS IN MARPOYAN DAMAI DISTRICT, PEKANBARU. The fact at this time is the increasing level of consumer consumption of beauty products. It does not only occur among adult women but also teenager. But the consumptive level not accompanied by purchasing power of quality products. Based on interviews with residents of the village of East Sidomulyo, most of the citizens are among adult women and teenagers that they mostly use ready-made masks that are sold in the market because it is more practical and faster in the process of use without considering the possibility of its contents which are harmful to skin health. The problem of the partners is to encourage service in the form of socialization and education to the local community to be able to take advantage of the banana peel waste that is widely available in the environment because it is now became popular a variety of processed banana products, but in terms of waste has not been utilized at all. This education is based on several studies that banana peels contain high antioxidants so it is very good if it can be processed as a mask for a facial skin care. In addition, the utilization of waste will be able to reduce pollution that might occur in the environment due to banana peels that are not treated. The existence of this activity was very welcomed by residents, this can be seen from the enthusiasm of residents asking questions regarding the problems presented and the impression of some residents who want this activity to be carried out continuously, so that more people feel the benefits and they are very enthusiastic to directly apply the knowledge.
