Based on these findings, we would advise sprint XC skiers to concurrently develop both these capacities, and to employ technical strategies where a high cycle rate can be sustained when fatigue occurs. However

high-intensity performance, several field tests were developed with the aim of evaluating the ability to sustain mainly aerobic exercise for a prolonged time ( 6 , 8 , 9 , 17 , 24 , 38 , 39 ). In this regard, the Yo-Yo tests proved to be feasible, valid, and reliable for determining maximal heart rate

The purpose of this article is to document a rotator cuff tear sustained by an elderly woman performing progressive resistance training (PRT) in a recent randomized controlled clinical trial. The patient was a sedentary 73-y-old Caucasian woman. Investigation revealed an acute, full-thickness tear of the right supraspinatus secondary to performing a shoulder press exercise. Further investigation via MRI revealed degenerative disease of the acromioclavicular joint including lateral downsloping of the acromion and an anteroinferior acromial spur, which would presdispose to impingement. Conservative management was implemented in this case for over 6 months with minimal success. The patient remained functionally limited in virtually all activities of daily living. Given the medical history, health status, physical condition, and age of our patient, it is probable that degenerative changes predisposed the patient to the injury. To our knowledge this is the first published report of an older adult sustaining a rotator cuff tear during PRT.

Many initiatives have been developed to facilitate older adults’ engagement in physical activity (PA) and document its benefits. One example is Texercise, a 12-week program with a focus on increasing participants’ self-efficacy. The goal of this paper is to augment the knowledgebase of PA program implementation and dissemination by elucidating the experience of Texercise implementation as perceived by multiple stakeholders. We conducted 28 semistructured stakeholder interviews and categorized the responses into four preset themes: (1) program delivery and advocacy; (2) value/merit of the program; (3) successes/challenges of offering and sustaining the program; and (4) recommendations for enhancing implementation and delivery. We identified emergent subthemes through further analysis. Many perceptions that are broadly applicable to community organizations emerged. Our findings highlight the importance of stakeholder support when embedding PA programs in communities. Furthermore, the findings are crucial to understanding underlying processes that support widespread program dissemination and sustainability.

Research on effects of acute physical exercise on performance in a concurrent cognitive task has generated equivocal evidence. Processing efficiency theory predicts that concurrent physical exercise can increase resource requirements for sustaining cognitive performance even when the level of performance is unaffected. This hypothesis was tested in a dual-task experiment. Sixty young adults worked on a primary auditory attention task and a secondary interval production task while cycling on a bicycle ergometer. Physical load (cycling) and cognitive load of the primary task were manipulated. Neither physical nor cognitive load affected primary task performance, but both factors interacted on secondary task performance. Sustaining primary task performance under increased physical and/or cognitive load increased resource consumption as indicated by decreased secondary task performance. Results demonstrated that physical exercise effects on cognition might be underestimated when only single task performance is the focus.

The purpose of this investigation was to study the pattern of habitual physical activity (HPA) and to assess the time spent in moderate to vigorous physical activity (MVPA) in kindergarten and first-grade schoolchildren. In 54 children, HPA was studied during 4 consecutive days by whole-day heart rate (HR) monitoring. MVPA was defined on the basis of HR threshold above 139 beats per minute. Sustained periods of MVPA of 20 or more minutes were observed only in 20% of boys and 17% of girls. However, the pattern of HPA of all children contained 1-min, and 2- to 4-min periods of MVPA, and 80% of boys and 90% of girls had 5- to 9-min sustained periods of MVPA. It can be concluded that in 4- to 8-year-old children, HPA is characterized by an intermittent pattern without prolonged periods of MVPA.

Mental health is a major concern for higher education and students are starting their college experience with psychological issues or developing mental health problems after enrollment. Because physical activity and exercise have known mental health benefits, the field of kinesiology can facilitate the delivery of physical activity and exercise programs aimed at reducing stress, anxiety, and depression, as well as promote healthy coping mechanisms. The School of Kinesiology at Auburn University has implemented a framework to address mental health on campus and within our community. Our framework consists of coursework, outreach efforts, and establishing key partnerships to facilitate the delivery and sustainability of our programs. Our programs enable individuals to establish self-regulation skills, use a mindfulness-based approach, or participate in yoga, thereby establishing effective and healthy coping mechanisms. This paper discusses the evolution of our framework, as well as barriers and facilitators of implementation and sustainability.
