“…The present study shows that HIIT training in obese older adults induces a decrease in waist and hip circumferences and improve functional capacities in both P20− and P20+ groups. Our results, therefore, strengthen the available literature showing that HIIT effectively improves overall muscle function and functional capacities in non-obese older adults [30,70]. Our results are also consistent with a recent meta-analysis suggesting that HIIT is an effective way to improve VO 2max and cardiometabolic risk factors (i.e., waist circumference) in adults [29].…”

“…Because older adults report lack of time for physical activity, high-intensity interval training (HIIT) has been highlighted as a promising aerobic intervention in elderly population due to its short duration. More importantly, it has been observed that HIIT improved body composition (total or appendicular fat and lean masses), muscle function (muscle mass and power), aerobic capacities (VO 2max ) or reduced cardiometabolic risk factors (waist circumference, waist-hip circumference ratio, diastolic blood pressure and fasting glucose levels) in older adults [26][27][28][29][30][31][32][33]. Finally, HIIT elicited similar or higher enjoyment and adherence levels than moderate-intensity continuous training [34,35].…”

Muscle adaptation in response to a high-intensity interval training in obese older adults: effect of daily protein intake distribution

et al. 2019

Background Aging is associated with declines in muscle mass, strength and quality, leading to physical impairments. An even protein distribution in daily meals has recently been proposed along with adequate total protein intake as important modulators of muscle mass. In addition, due to its short duration, high-intensity interval training (HIIT) has been highlighted as a promising intervention to prevent physical deterioration. However, the interaction between daily protein intake distribution and HIIT intervention in elderlies remain unknown. Objective To investigate muscle adaptation following HIIT in older adults according to daily protein intake distribution. Methods Thirty sedentary obese subjects who completed a 12-week elliptical HIIT program were matched [criteria: age (± 2 years), sex, BMI (± 2 kg/m 2 )] and divided a posteriori into 2 groups according to the amount of protein ingested at each meal: < 20 g in at least one meal (P20−, n = 15, 66.8 ± 3.7 years) and ≥ 20 g in each meal (P20+, n = 15, 68.1 ± 4.1 years). Body composition, functional capacity, muscle strength, muscle power, physical activity level, and nutritional intakes were measured pre-and post-intervention. A two way repeated ANOVA was used to determine the effect of the intervention (HIIT) and protein distribution (P20− vs P20+, p < 0.05). Results No difference was observed at baseline between groups. Following the HIIT intervention, we observed a significant decrease in waist and hip circumferences and improvements in functional capacities in both P20− and P20 + group (p < 0.05). However, no protein distribution effect was observed. Conclusion A 12-week HIIT program is achievable and efficient to improve functional capacities as well as body composition in obese older adults. However, consuming at least 20 g of proteins in every meal does not further enhance muscle performance in response to a 12-week HIIT intervention.

Lifelong exercise is associated with regulation of skeletal mass and function, reductions in frailty, and successful aging. Yet, the influence of exercise on myostatin and myostatin‐interacting factors is relatively under examined in older males. Therefore, we investigated whether serum total myostatin, free myostatin, follistatin, and growth and differentiation factor 11 (GDF11) were altered following high‐intensity interval training (HIIT) in a group of 13 lifelong sedentary (SED; 64 [6] years) and 11 lifelong exercising (LEX; 62 [6] years) older males. SED follistatin was moderately greater than LEX pre‐HIIT (Cohen's d = 0.66), and was largely greater post‐HIIT (Cohen's d = 1.22). The HIIT‐induced increase in follistatin was large in SED (Cohen's d = 0.82) and absent in LEX (Cohen's d = 0.03). GDF11 was higher in LEX pre‐HIIT (Cohen's d = 0.49) and post‐HIIT (Cohen's d = 0.63) compared to SED. HIIT resulted in no change to GDF11 in LEX or SED (Cohen's d = 0.00–0.03). Peak power output and GDF11 were correlated (r = 0.603), independent of grouping. Differences in GDF11 with lifelong exercise training, paired with the correlation between GDF11 and peak power output, suggested that GDF11 may be a relevant myostatin‐interacting peptide to successful aging in humans, and strategies to maintain this need to be further explored.

“…After the adaptation phase, were performed three sets of 10-15 repetitions in the initial six weeks, with an approximate intensity of 40-50% of the SPE scale (score between 9-11). In the following six weeks the three sets of 6-10 repetitions were maintained, increasing the intensity to 60-70% of the scale (score between [12][13][14]. The interval between the series was of 90 seconds, and the load adjusted weekly, from the scale of subjective perception of effort (SPE) (Row, Knutzen and Skogsberg; 2012).…”

“…Also, there is evidence on the association between low muscle power and the presence of falls (6,11) , and positive interactions between PT training and the functionality of the elderly (12,13) , and these findings were not unanimous (14,15) . Despite the undoubted relevance of these health parameters, it is believed that at this stage of life individual health perceptions should be considered, supported by the theory that objective measures of physiological and functional anatomical parameters do not always coincide with the elderly's understanding of their condition (16,17) .…”

Introduction:The muscular strength exercises can be an effective intervention to prevent falls and to favor the functional capacity (FC) in the elderly. However, few studies have reported the benefits of power training (PT) and the subjective perception of the elderly on these activities. Objective: to evaluate the repercussions of a power training protocol on functional capacity and subjective health parameters in the elderly. Method: It was a prospective study involving 48 elderly people. Two groups were composed: a power training group (PG) with 22 participants with a mean age of 68.14 (5.46) years and the control group (CG) was composed of 32 elderly individuals aged 68.03 (4.83) years. Health-related quality of life was measured from the Medical Outcomes Study 36 -Item Short-Form Health Survey (SF-36). The FC was measured by the Berg Balance and Time Up and Go tests. The PT was performed 2x/week, with duration of 50 min/session, for 14 weeks (first two weeks of adaptation; first six weeks 3X/10-15 repetitions of 40-50% of the Subjective Perceived Exertion (SPE) / 6 following weeks 3X/6-10 repetitions of 60-70% of the SPE). The CG performed rhythm activities with the same frequency and weekly duration. Result: It was observed favorable results in FC after 14 weeks of power training. There was also a positive evaluation of most sf-36 domains, with emphasis on physical and emotional aspects. However, the perception of the elderly in relation to the pain domain presented negative results. Conclusion: The PT positively influenced the FC, the physical and the emotional aspects of the elderly; negatively affected the pain and maintained the low risk of fall after 12 weeks of intervention, without presenting intercurrences during the intervention.
