Current aspects of high-intensity interval training for older adults: a narrative review

Journal of Physical Fitness and Sports Medicine, 2022
Negative aspects of aging include a decrease in muscle mass/strength and maximal oxygen consumption (VO2max). The most beneficial and adaptable protocol among the various exercise methods should be explored in older adults.

The efficacy and physiological bases of small muscle mass exercise in health and disease

Experimental Physiology, EarlyView.
Abstract The conventional approach to aerobic exercise prescription involves large muscle mass exercise and the manipulation of variables such as training intensity, duration and frequency to promote desired adaptations. However, during whole‐body exercise, central limitations (i.e., neural, pulmonary and/or cardiac) constrain exercise tolerance and ...

Differences between genders in anaerobic capacity during a supramaximal effort

Motriz: Revista de Educacao Fisica, 2019
Aim: The present study aimed to verify if there is a difference between genders in anaerobic capacity estimated by energetic equivalents of glycolytic and phosphagen pathways (AC[La-]+EPOCfast).

Metabolic and blood flow responses to single leg emphasis cycling compared to single and double leg cycling

Experimental Physiology, EarlyView.
Abstract Single leg emphasis cycling (SLEC) has the potential to be beneficial in the rehabilitation setting; however, the metabolic responses to it are unknown. Thus, the current investigation sought to evaluate the metabolic and blood flow responses of SLEC compared to traditional double leg cycling (DLC) and single leg cycling (SLC).

Effect of Ischemic Preconditioning on the Recovery of Cardiac Autonomic Control From Repeated Sprint Exercise

Frontiers in Physiology, 2018
Repeated sprint exercise (RSE) acutely impairs post-exercise heart rate (HR) recovery (HRR) and time-domain heart rate variability (i. e., RMSSD), likely in part, due to lactic acidosis-induced reduction of cardiac vagal reactivation.

A comparison of the neuromuscular, cardiopulmonary and muscle oxygenation responses to single‐ and double‐leg cycling in older adults

Experimental Physiology, EarlyView.
Abstract Previous work in younger adults has shown that during small muscle mass exercise, the tolerable degree of neuromuscular impairment at task failure is greater than during large muscle mass exercise. However, no study has compared the neuromuscular responses to small and large muscle mass exercise whilst matching exercise modality in older ...

Mitochondrial haplotype and sex modulate responses to endurance exercise training

The Journal of Physiology, EarlyView.
Abstract figure legend Using OKC‐HETB/W rats we demonstrate that mitochondrial haplotype influences training responses of endurance exercise. Overall OKC‐HETW rats showed greater responses than OKC‐HETB in exercise tolerance, mitochondrial bioenergetics, mitochondrial DNA (mtDNA) mutation frequencies and motor co‐ordination.

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session
