“…However, this result did not reach statistical significance ( t [34.7] = 1.1, p = .28; Figure b), likely due to the large variability in change in CRF following exercise training (Lundby, Montero, & Joyner, ). The trend for improvement in CRF from baseline for the RT group is perhaps not surprising given the study design of using an active exercise group, and is consistent with a recent meta‐analysis that demonstrated RT can significantly improve

Improving fitness increases dentate gyrus/CA3 volume in the hippocampal head and enhances memory in young adults

Converging evidence suggests a relationship between aerobic exercise and hippocampal neuroplasticity that interactively impacts hippocampally dependent memory.The majority of human studies have focused on the potential for exercise to reduce brain atrophy and attenuate cognitive decline in older adults, whereas animal studies often center on exercise-induced neurogenesis and hippocampal plasticity in the dentate gyrus (DG) of young adult animals. In the present study, initially sedentary young adults (18-35 years) participated in a moderate-intensity randomized controlled exercise intervention trial (ClinicalTrials.gov; NCT02057354) for a duration of 12 weeks. The aims of the study were to investigate the relationship between change in cardiorespiratory fitness (CRF) as determined by estimated _ VO 2MAX , hippocampally dependent mnemonic discrimination, and change in hippocampal subfield volume.Results show that improving CRF after exercise training is associated with an increased volume in the left DG/CA3 subregion in young adults. Consistent with previous studies that found exercise-induced increases in anterior hippocampus in older adults, this result was specific to the hippocampal head, or most anterior portion, of the subregion. Our results also demonstrate a positive relationship between change in CRF and change in corrected accuracy for trials requiring the highest level of discrimination on a putative behavioral pattern separation task. This relationship was observed in individuals who were initially lower-fit, suggesting that individuals who show greater improvement in their CRF may receive greater cognitive benefit. This work extends animal models by providing evidence for exercise-induced neuroplasticity specific to the neurogenic zone of the human hippocampus.

“…For example, search strategies for seven meta-analyses were critically limited to five online databases or less (Chou, Hwang, & Wu, 2012; de Vries et al, 2012; Gine-Garriga et al, 2010; Gu & Conn, 2008; Howe, Rochester, Neil, Skelton, & Ballinger, 2011; Nicola & Catherine, 2011; Yamamoto, Hotta, Ota, Mori, & Matsunaga, 2015). The most common databases searched were Medline, PubMed, and CINAHL, all of which house similarly indexed citations.…”

The purpose of this systematic review and meta-analysis was to determine the effects of supervised resistance and/or aerobic training physical activity interventions on performance-based measures of physical functioning among community-dwelling older adults, and to identify factors impacting intervention effectiveness. Diverse search strategies were used to identify eligible studies. Standardized mean difference effect sizes (d, ES) were synthesized using a random effects model. Moderator analyses were conducted using subgroup analyses and meta-regression. Twenty-eight studies were included. Moderator analyses were limited by inconsistent reporting of sample and intervention characteristics. The overall mean ES was 0.45 (k=38, p=<.01), representing a clinically meaningful reduction of 0.92 seconds in the Timed Up and Go for treatment versus control. More minutes per week (p<.01) and longer intervention session duration (p<0.01) were associated with larger effects. Interventions were especially effective among frail participants (d=1.09). Future research should clearly describe sample and intervention characteristics and incorporate frail populations.

“…This controversy is evident in clinical practice 8 as well as in the available study results, where the training intensity has been set between 30 and 80% of one repetition maximum (1RM), which makes it difficult to evaluate the overall results. [8][9][10] The former reluctance to implement resistance training in cardiac rehabilitation was mainly based on the caution that its performance may lead to an inadequate blood pressure response and/or other inadequate cardiovascular responses. However, an inadequate response can be avoided by taking into account influencing factors, such as the mode of exercise (the isometric/isotonic components), the amount of the muscle mass used, the exercise intensity, the number and speed/rhythm of repetitions, the duration of loading, the number of sets and the resting period between sets.…”

“…7 Musculoskeletal comorbidities are common on admission to cardiac rehabilitation. 20,21 In addition, an increasing deconditioning of the skeletal muscle with a reduction in muscle mass (sarcopenia) and muscle strength is to expected in elderly patients, 9,21 in patients with diabetes mellitus 22 and in patients with a reduced left ventricular ejection fraction. 23 Furthermore, the majority of patients admitted to cardiac rehabilitation have no or little experience in resistance exercise and/or the use of the equipment.…”
