Authors: Casper JM, Jeon JH Abstract The purpose of this study was to examine psychological connection to the sport of pickleball by investigating active older adults (55 years and older) in relation to behavioral involvement and motives for participation. Data were collected via an online survey of a representative sample of active pickleball players in North Carolina (N = 690). The Psychological Continuum Model (PCM: Funk, 2008) categorized players into four distinct connection levels of Awareness, Attraction, Attachment, and Allegiance. Participants on each PCM level were analyzed based on playing length, play f...

Physical Activity Level and Risk of Falling in Community-Dwelling Older Adults: Systematic Review and Meta-Analysis.
Authors: Soares WJS, Lopes AD, Nogueira E, Candido V, Moraes SA, Perracini MR Abstract This systematic review examines the association between physical activity (PA) level and risk of falling in community-dwelling older adults. A search of PubMed, Embase, CINAHL, Sport Discus, and Web of Science was performed in January 2017. Four prospective cohort studies investigating the incidence of falls in a period of at least 12 months and its association with the level of PA in people 60-plus years old were reviewed and pooled for meta-analysis. The pooled risk ratio for being a recurrent faller (2,420 participants) was 39...

The Effects of Poi on Physical and Cognitive Function in Healthy Older Adults.
This study investigated the effects of poi (a weight on the end of a cord which is swung in circular patterns around the body) compared to Tai Chi on physical and cognitive function in healthy older adults. Seventy-nine participants (60 - 86 years) were randomly allocated to the poi or Tai Chi group. Physical and cognitive function were measured one month before, immediately before, immediately after, and one month after the intervention (2 lessons a week for 4 weeks). Immediately post intervention both groups improved postural stability, upper limb strength, and simple attention. Tai Chi also improved systolic blood press...

Age Does Not Attenuate Maximal Velocity Adaptations in the Ipsilateral and Contralateral Limbs During Unilateral Resistance Training.
This study examined the effects of unilateral resistance training (RT) on maximal velocity parameters in the ipsilateral and contralateral legs in young and older males. Young (n = 22; age = 21.55 ± 2.23 yrs) and older (n = 20; age = 65.10 ± 9.65 yrs) males were assigned to training or control groups. Unilateral isokinetic RT of the knee extensors was performed for 4 weeks. Peak velocity (PV) and acceleration were identified during a dynamic maximal voluntary contraction before, at week 2, and after week 4 (POST) of RT. Age independent increases in PV (1.5%) and acceleration (4.5%) were demonstrated at POST f...

Physical Activity in Relation to Sleep Among Community-Dwelling Older Adults in China.
Authors: Li J, Yang B, Varrasse M, Ji X, Wu M, Li M, Li K Abstract This cross-sectional study was conducted to describe physical activity and sleep in 290 community-dwelling Chinese older adults and to examine the association between physical activity and poor sleep outcomes. Almost half of the sample were poor sleepers. The majority of the sample regularly participated in walking, some household activity and light sports; yet, only a small portion were involved in work-related activity or in strenuous sports. A greater level of overall physical activity [Odds Ratio (OR) =0.79, 95% confidence interval (CI) = (0.73,...

Feasibility of an Outdoor Mindful Walking Program for Reducing Negative Affect in Older Adults.
This study evaluated the feasibility, acceptability, sustainability, and preliminary efficacy of a mindful walking program for reducing negative affect in older adults. Community-dwelling older adults (n = 29) completed a one-month, outdoor mindful walking program distributed across eight 30-minute sessions. Responses from the post-program and the follow-up questionnaires revealed that mindful walking was well-accepted, highly-valued, and maintained after the program ended. Analysis from the pre-walk and post-walk surveys also suggested the preliminary efficacy of mindful walking program for reducing negative affect. Posit...

Effects of Corrective Training on Drop Landing Ground Reaction Force Characteristics and Lower Limb Kinematics in Older Adults With Genu Valgus: A Randomized Controlled Trial.
Authors: Jafarnezhadgero A, Madadi-Shad M, McCrum C, Karamanidis K Abstract The aim of this study was to identify the effects of a corrective exercise program on landing ground reaction force characteristics and lower limb kinematics in older adults with genu valgus. Twenty six older male adults with genu valgus were randomized into two groups. An experimental group conducted a 14- week corrective exercise program, while a control group did not perform any exercise. The experimental group displayed lower peak vertical, peak anterior and posterior, and peak medial ground reaction force components during the post-tes...
