Baxter BA, Baross AW, Ryan DJ, Kay AD. Effects of detraining on neuromuscular function and structural adaptations following once- or twice-weekly eccentric resistance training in older adults. Aging Clin Exp Res 2024; 36:177. [PMID: 39172298 PMCID: PMC11341597 DOI: 10.1007/s40520-024-02828-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Accepted: 08/01/2024] [Indexed: 08/23/2024]
Abstract
BACKGROUND Eccentric resistance training elicits greater preservation of training-induced muscular adaptations compared with other training modalities, however the detraining profiles of different training dosages remain unknown. AIMS To examine the detraining effects following once- or twice-weekly eccentric-specific resistance training in older adults. METHODS Twenty-one older adults (age = 70.5 ± 6.0 year) completed a 12-week detraining period following the 12-week eccentric training programmes with neuromuscular function and muscle structure assessed six (mid-detraining) and 12 (post-detraining) weeks following training cessation. RESULTS From post-training to post-detraining, no significant regression of the training-induced improvements (collapsed group data reported) occurred in power (0%), strength (eccentric = 0%, isometric = 39%), or explosive strength over numerous epochs (0-32%), resulting in values that remained significantly greater than at pre-training. However, significant regression in the improvements in muscle thickness (91%) and fascicle angle (100%) occurred, resulting in values that were not significantly greater than pre-training. DISCUSSION The limited regression in neuromuscular function following a 12-week detraining period has important implications for supporting eccentric exercise prescription in older adults who often face periods of inactivity. However, further work is required to develop an effective maintenance dosage strategy that preserves improvements in muscle structure. CONCLUSIONS Eccentric resistance training elicits improvements in the neuromuscular function of older adults, which are sustained for at least 12 weeks after eccentric training cessation.

Leitão L, Campos Y, Louro H, Figueira ACC, Figueiredo T, Pereira A, Conceição A, Marinho DA, Neiva HP. Detraining and Retraining Effects from a Multicomponent Training Program on the Functional Capacity and Health Profile of Physically Active Prehypertensive Older Women. Healthcare (Basel) 2024; 12:271. [PMID: 38275551 PMCID: PMC10815818 DOI: 10.3390/healthcare12020271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 01/12/2024] [Accepted: 01/19/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND Resuming a physical exercise program after a period of cessation is common in older women. Monitoring the responses during this detraining (DT) and retraining (RT) may allow us to analyze how the body reacts to an increase and a reduction in physical inactivity. Therefore, we conducted a follow-up training, DT, and RT in prehypertensive older women to analyze the response to these periods. METHODS Twenty-three prehypertensive older women (EG; 68.3 ± 2.8 years; 1.61 ± 0.44 m) performed 36 weeks of the multicomponent training program (MTP) followed by twelve weeks of DT plus eight weeks of RT. Fifteen prehypertensive older women (CG; 66.3 ± 3.2 years; 1.59 ± 0.37 m) maintained their normal routine. Functional capacity (FC), lipid, and hemodynamic profile were assessed before, during 24 and 36 weeks of the MTP, after 4 and 12 weeks of DT, and after 8 weeks of RT. RESULTS After 24 weeks of the MTP, only SBP did not improve. Four weeks of DT did not affect lower body strength (30-CS), TC, or GL. Eight weeks of RT improved BP (SBP: -2.52%; ES: 0.36; p < 0.00; DBP: -1.45%; ES: 0.44; p < 0.02), handgrip strength (3.77%; ES: 0.51; p < 0.00), and 30-CS (3.17%; ES: 0.38; p < 0.04) compared with 36 weeks of the MTP. CONCLUSIONS Eight weeks of RT allowed patients to recover the benefits lost with detraining, which after only four weeks affected them negatively, and the systematic practice of exercise contributed to greater regulation of BP since 24 weeks of the MTP proved not to be enough to promote positive effects of SBP.

Three-Month vs. One-Year Detraining Effects after Multicomponent Exercise Program in Hypertensive Older Women. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19052871. [PMID: 35270564 PMCID: PMC8910620 DOI: 10.3390/ijerph19052871] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 02/08/2022] [Accepted: 02/24/2022] [Indexed: 01/01/2023]
Abstract
Background: Chronic diseases are the leading causes of death and disability in older women. Physical exercise training programs promote beneficial effects for health and quality of life. However, exercise interruption periods may be detrimental for the hemodynamic and lipidic profiles of hypertensive older women with dyslipidemia. Methods: Nineteen hypertensive older women with dyslipidemia (exercise group: 67.5 ± 5.4 years, 1.53 ± 3.42 m, 71.84 ± 7.45 kg) performed a supervised multicomponent exercise training program (METP) during nine months, followed by a one-year detraining period (DT), while fourteen hypertensive older women (control group: 66.4 ± 5.2 years, 1.56 ± 3.10 m, 69.38 ± 5.24 kg) with dyslipidemia kept their continued daily routine without exercise. For both groups, hemodynamic and lipidic profiles and functional capacities (FCs) were assessed four times: before and after the METP and after 3 and 12 months of DT (no exercise was carried out). Results: The METP improved hemodynamic and lipidic profiles (p < 0.05), while three months of DT decreased all (p < 0.05) parameters, with the exception of diastolic blood pressure (DBP). One year of DT significantly (p < 0.01) decreased systolic blood pressure (7.85%), DBP (2.29%), resting heart rate (7.95%), blood glucose (19.14%), total cholesterol (10.27%), triglycerides (6.92%) and FC—agility (4.24%), lower- (−12.75%) and upper-body strength (−12.17%), cardiorespiratory capacity (−4.81%) and lower- (−16.16%) and upper-body flexibility (−11.11%). Conclusion: Nine months of the exercise program significantly improved the hemodynamic and lipid profiles as well as the functional capacities of hypertensive older women with dyslipidemia. Although a detraining period is detrimental to these benefits, it seems that the first three months are more prominent in these alterations.

Does a Multicomponent Exercise Program Improve Physical Fitness in Older Adults? Findings From a 5-Year Longitudinal Study. J Aging Phys Act 2021; 29:814-821. [PMID: 33761457 DOI: 10.1123/japa.2020-0070] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 09/22/2020] [Accepted: 11/17/2020] [Indexed: 11/18/2022]
Abstract
The objective was to assess the physical fitness of older adults participating in a 5-year multicomponent exercise program. The sample consisted of 138 older adults aged 60-93 years (70.4 ± 7.8 years) evaluated with the Senior Fitness Test (muscle strength, flexibility, balance, and cardiorespiratory fitness). The multicomponent program was carried out between the months of March and November of each year. Data were analyzed using generalized estimating equations (factor year: Year 1, Year 2, Year 3, Year 4, and Year 5; factor time: pretest and posttest) with Bonferroni's post hoc test. Participation in the multicomponent exercise program for 5 years (baseline pretest Year 1 and follow-up Year 5) improved lower and upper limb strength, lower limb flexibility, and balance and cardiorespiratory fitness, while upper limb flexibility was maintained. Year-by-year analysis revealed variable patterns for each fitness parameter. The results of this study show the potential benefits of implementing a long-term community-based exercise program.

Maintenance of muscle strength following a one-year resistance training program in older adults. Exp Gerontol 2020; 139:111049. [PMID: 32781112 DOI: 10.1016/j.exger.2020.111049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 07/06/2020] [Accepted: 07/30/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Muscle mass, strength and function declines with advancing age. Strength training (ST) improves these parameters in older adults, but the gains often disappear after completion of a short-term intervention. The purpose of the present study was to investigate muscle mass, -strength and -function one year after the completion of a successful long-term (12 months) supervised ST program in older adults. METHOD Men and women (n = 419, age: 62-70 years) completed one year of supervised heavy resistance training (HRT, n = 143) or moderate intensity resistance training (MIT, n = 144) and were compared to a non-exercising control group (CON, n = 132). At 1-year follow-up, 398 participants returned for measurements of muscle power, -strength and -mass, physical function, body composition, hippocampus volume and physical/mental well-being. The results were compared to pre-training (baseline) and post-training (1-year) values. Further, the participants from the two previous training groups (HRT + MIT, n = 265) were divided into 1) those who on their own continued the ST program (>9 months) the year after completion of the supervised ST program (CONTIN, n = 65) and 2) those who stopped during the follow-up year (<9 months) (STOP, n = 200). RESULTS Out of all the improvements obtained after the 1-year training intervention, only knee extensor muscle strength in HRT was preserved at 1-year follow-up (p < 0.0001), where muscle strength was 7% higher than baseline. Additionally, the decrease in muscle strength over the second year was lower in CONTIN than in STOP with decreases of 1% and 6%, respectively (p < 0.05). Only in CONTIN was the muscle strength still higher at 1-year follow-up compared with baseline with a 14% increase (p < 0.0001). The heavy strength training induced increase in whole-body lean mass was erased at 1-year follow-up. However, there was a tendency for maintenance of the cross-sectional area of m. vastus lateralis from baseline to 1-year follow-up in HRT compared with CON (p = 0.06). Waist circumference decreased further over the second year in CONTIN, whereas it increased in STOP (p < 0.05). CONCLUSION Even though long-term strength training effectively improved muscle function and other health parameters in older adults, only knee extensor muscle strength was preserved one year after completion of heavy (but not moderate intensity) resistance training. Continuation of strength training resulted in better maintenance of muscle strength and health, which indicates that it is required to continue with physical activity to benefit from the long-term effects of strength training upon muscle function and health in older men and women.

Arch Gerontol Geriatr 2020; 91:104191. [PMID: 32717587 DOI: 10.1016/j.archger.2020.104191] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 07/15/2020] [Accepted: 07/19/2020] [Indexed: 11/19/2022]
Abstract
PURPOSE This research was aimed at evaluating the effects of a five-month detraining period on the functional fitness level of a group of non-institutionalized and active older adults after taking part in a multi-component training program. A secondary aim was to determine how usual physical activity (PA) levels vary due to cessation of the program. METHODS We tested sixty-five older people (mean age: 77.1 ± 6.2; 83% women) during the final week of an 8-month multi-component training program and during the first week after its resumption (five months later). We used the senior fitness test and the Minnesota Questionnaire to assess their functional fitness and their PA levels respectively. RESULTS We observed a significant worsening of lower-limb strength (p = 0.008), shoulder range of motion (p = 0.004), and dynamic balance (p < 0.001) once the detraining period was completed. There was a slight downward trend in the remaining functional fitness dimensions, and there were significant differences when comparing the amount of PA estimated at pre-detraining and post-detraining (5155 ± 2258 vs 3937 ± 2087 MET-min·wk-1; p < 0.001). Older adults classified as very active showed a non-significant trend to smaller decreases in functional fitness once the detraining period was over, in comparison with those considered active. CONCLUSIONS Active older people who regularly participated in a multicomponent training program showed a significant reduction in their strength, range of motion, and dynamic balance levels after a five-month detraining period. Self-reported PA decreased significantly during this time frame. Effective strategies are needed to increase PA levels in older people when systematic training programs are temporarily interrupted.

Effects of Three Months of Detraining on the Health Profile of Older Women after a Multicomponent Exercise Program. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16203881. [PMID: 31614946 PMCID: PMC6843996 DOI: 10.3390/ijerph16203881] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Revised: 10/07/2019] [Accepted: 10/09/2019] [Indexed: 11/17/2022]
Abstract
Physical exercise results in very important benefits including preventing disease and promoting the quality of life of older individuals. Common interruptions and training cessation are associated with the loss of total health profile, and specifically cardiorespiratory fitness. Would detraining (DT) promote different effects in the cardiorespiratory and health profiles of trained and sedentary older women? Forty-seven older women were divided into an experimental group (EG) and a control group (CG) (EG: n = 28, 70.3 ± 2.3 years; CG: n = 19, 70.1 ± 5.6 years). Oxygen uptake (VO2) and health profile assessments were conducted after the exercise program and after three months of detraining. The EG followed a nine-month multicomponent exercise program before a three-month detraining period. The CG maintained their normal activities. Repeated measures ANOVA showed significant increases in total heath and VO2 (p < 0.01) profile over a nine-month exercise period in the EG and no significant increases in the CG. DT led to greater negative effects on total cholesterol (4.35%, p < 0.01), triglycerides (3.89%, p < 0.01), glucose (4.96%, p < 0.01), resting heart rate (5.15%, p < 0.01), systolic blood pressure (4.13%, p < 0.01), diastolic blood pressure (3.38%, p < 0.01), the six-minute walk test (7.57%, p < 0.01), Pulmonary Ventilation (VE) (10.16%, p < 0.01), the Respiratory Exchange Ratio (RER) (9.78, p < 0.05), and VO2/heart rate (HR) (16.08%, p < 0.01) in the EG. DT may induce greater declines in total health profile and in VO2, mediated, in part, by the effectiveness of multicomponent training particularly developed for older women.
