“…These findings lend support to the positive effects of high-intensity exercise as an effective and time-efficient method of improving cardiorespiratory fitness and cardiac mass in sedentary adults (20). However, we have also demonstrated for the first time that even a total duration of 10 min of sub-maximal exercise (relative and absolute workloads) increase circulating irisin levels.…”

Background: Irisin, a recently discovered myokine, has been shown to induce browning of white adipose tissue, enhancing energy expenditure and mediating some of the beneficial effects of exercise. We aimed to estimate the time frame of changes in irisin levels after acute exercise and the effect of different exercise workloads and intensities on circulating irisin levels immediately post-exercise. Methods: In a pilot study, four healthy subjects (22.5G1.7 years) underwent maximal workload exercise (maximal oxygen consumption, VO 2 max ) and blood was drawn at prespecified intervals to define the time frame of pre-and post-exercise irisin changes over a 24-h period. In the main study, 35 healthy, non-smoking (23.0G3.3 years) men and women (nZ20/15) underwent three exercise protocols R48-h apart, in random order: i) maximal workload (VO 2 max ); ii) relative workload (70% of VO 2 max /10 min); and iii) absolute workload (75 W/10 min). Blood was drawn immediately pre-exercise and 3 min post-exercise. Results: In the pilot study, irisin levels increased by 35% 3 min post-exercise, then dropped and remained relatively constant. In the main study, irisin levels post-exercise were significantly higher than those of pre-exercise after all workloads (all, P!0.001). Post-to-pre-exercise differences in irisin levels were significantly different between workloads (PZ0.001), with the greatest increase by 34% following maximal workload (PZ0.004 vs relative and absolute). Conclusions: Circulating irisin levels were acutely elevated in response to exercise, with a greater increase after maximal workload. These findings suggest that irisin release could be a function of muscle energy demand. Future studies need to determine the underlying mechanisms of irisin release and explore irisin's therapeutic potential.

ObjectivesTo compare the effects of interval training and moderate-intensity continuous training (MOD) on body adiposity in humans, and to perform subgroup analyses that consider the type and duration of interval training in different groups.DesignSystematic review and meta-analysis.Data sourcesEnglish-language, Spanish-language and Portuguese-language searches of the electronic databases PubMed and Scopus were conducted from inception to 11 December 2017.Eligibility criteria for selecting studiesStudies that met the following criteria were included: (1) original articles, (2) human trials, (3) minimum exercise training duration of 4 weeks, and (4) directly or indirectly compared interval training with MOD as the primary or secondary aim.ResultsOf the 786 studies found, 41 and 36 were included in the qualitative analysis and meta-analysis, respectively. Within-group analyses showed significant reductions in total body fat percentage (%) (interval training: −1.50 [95% CI −2.14 to −0.86, p<0.00001] and MOD: −1.44 [95% CI −2.00 to −0.89, p<0.00001]) and in total absolute fat mass (kg) (interval training: −1.58 [95% CI −2.74 to −0.43, p=0.007] and MOD: −1.13 [95% CI −2.18 to −0.08, p=0.04]), with no significant differences between interval training and MOD for total body fat percentage reduction (−0.23 [95% CI −1.43 to 0.97], p=0.705). However, there was a significant difference between the groups in total absolute fat mass (kg) reduction (−2.28 [95% CI −4.00 to −0.56], p=0.0094). Subgroup analyses comparing sprint interval training (SIT) with MOD protocols favour SIT for loss of total absolute fat mass (kg) (−3.22 [95% CI −5.71 to −0.73], p=0.01). Supervised training, walking/running/jogging, age (<30 years), study quality and intervention duration (<12 weeks) favourably influence the decreases in total absolute fat mass (kg) observed from interval training programmes; however, no significant effect was found on total body fat percentage (%). No effect of sex or body mass index was observed on total absolute fat mass (kg) or total body fat percentage (%).ConclusionInterval training and MOD both reduce body fat percentage (%). Interval training provided 28.5% greater reductions in total absolute fat mass (kg) than MOD.Trial registration numberCRD42018089427.

“…Using a lowfrequency protocol comprising one session per week with bouts at 80 % maximum work rate to volitional exhaustion, they demonstrated a 13 % increase inV O 2max over 3 months. Similarly, there is evidence that reducing the volume of work within HIIT sessions, but maintaining their frequency at three sessions per week does not adversely impact on the improvements in aerobic capacity in young men (Matsuo et al 2014;Zelt et al 2014).…”

“…There is an emergent body of evidence that endorses HIIT as an effective alternative to traditional endurance training that can yield improvements in both cardiorespiratory fitness and variety of health outcomes. Previous (Pollock, 1977) and more recent supporting evidence has demonstrated that a single HIIT exercise session, performed once per week, can improveV O 2max in young adults (Matsuo et al 2014;Nakahara et al 2014) and a recent metaanalysis of low-volume HIIT acknowledged the young age of participants enrolled to such studies and further proposed that studies using older participants were required to clarify the effects of low-volume HIIT in older participants (Weston et al 2014b). …”

There is a demand for effective training methods that encourage exercise adherence during advancing age, particularly in sedentary populations. This study examined the effects of high-intensity interval training (HIIT) exercise on health-related quality of life (HRQL), aerobic fitness and motivation to exercise in ageing men. Participants consisted of males who were either lifelong sedentary (SED; N=25; age 63±5 years) or lifelong exercisers (LEX; N=19; aged 61±5 years).V O 2max and HRQL were measured at three phases: baseline (Phase A), week seven (Phase B) and week 13 (Phase C). Motivation to exercise was measured at baseline and week 13.VO 2max was significantly higher in LEX (39.2±5.6 ml kg min −1 ) compared to SED (27.2 ±5.2 ml kg min −1 ) and increased in both groups from Phase A to C (SED 4.6±3.2 ml kg min −1 , 95 % CI 3.1 -6.0; LEX 4.9±3.4 ml kg min −1 , 95 % CI 3.1-6.6) Physical functioning (97±4 LEX; 93±7 SED) and general health (70±11 LEX; 78±11 SED) were significantly higher in LEX but increased only in the SED group from Phase A to C (physical functioning 17±18, 95 % CI 9-26, general health 14±14, 95 % CI 8-21). Exercise motives related to social recognition (2.4±1.2 LEX; 1.5 ±1.0 SED), affiliation (2.7±1.0 LEX; 1.6±1.2 SED) and competition (3.3±1.3 LEX; 2.2±1.1) were significantly higher in LEX yet weight management motives were significantly higher in SED (2.9±1.1 LEX; 4.3± 0.5 SED). The study provides preliminary evidence that low-volume HIIT increases perceptions of HRQL, exercise motives and aerobic capacity in older adults, to varying degrees, in both SED and LEX groups.Keywords Ageing men .
