Background: Assessments of muscle strength help prescribe and monitor training loads in cyclists (e.g., triathletes). Some methods include repetition maximum, joint isokinetic tests, indirect estimates. However, their specificity for cycling’s dynamic force application competitive cadences is lacking. This study aims to determine the influence cycling peak (cIPF) at different on aerobic performance-related variables trained triathletes. Methods: Eleven male athletes (33 ± 9.8 years, 173.1 5.0 cm height, 73.9 6.8 kg body mass, ≥5 years triathlon experience) were recruited. Maximal oxygen consumption (VO2 max), ventilatory thresholds (i.e., VT1 VT2), cIPF assessed. testing involved 10 s sprints varied with 4 min rest intervals.

Conclusions: highlights significance cIPF, particularly cadences, as a determinant aerobic-related Cycling should be tested understand an athlete’s profile during crank cycling, informing better practice ultimately supporting achieving optimal performance outcomes events.

The majority of "specialised" exercise configurations (e.g., supersets, drop sets, blood flow restriction) are being assessed as "shortcuts" to hypertrophy and strength improvements. However, these advanced training techniques may also offer significant benefits for systemic health functional outcomes across recreational clinical populations via locally induced metabolic responses. Stress-regulating mechanisms known enhance the body's resilience by facilitating allostasis, process coordinating adaptive processes in reaction stressors such physical training. Yet, role local stress provoked resistance has not gained much research attention despite its wide potential. Positive effects only linked improved muscular endurance, primary secondary mechanisms, but release myokines, hormones, microRNAs, immune factors, inflammatory substances other endocrine molecules that initiate numerous health-promoting modifications on a level. Resistance strategies maximise accumulation metabolites well defined, although high volume, close proximity failure shorter rests seem be necessity. Additionally, restriction provides potent alternative inducing acidosis, thereby triggering several pathways associated with immunity function even remote muscle tissues. Future is warranted further explore techniques, approaches comparable mental those seen forms high-intensity interval heavy

Purpose: To investigate the influence of upper body (UB) strength qualities and UB training on performance high-intensity running jumping actions to identify gaps recommendations for future research. Methods: A systematic search using PRISMA Scoping Review protocol was conducted in February 2024 PubMed, Scopus, ICTRP. Studies eligible inclusion were those that reported associations between or trunk maximal (e.g., absolute strength, forces, power) investigated an isolated intervention performances. Results: Of 4730 articles, 7 studies met criteria, reporting correlations 16 tests. No identified. Preliminary findings limited number highlight greater strength-generating capacity may positively repeated sprint ability. While a significant moderate correlation faster “flying” also reported, mixed results found acceleration. There is evidence change-of-direction greatly benefit from high isometric all muscles strong extensors enhance drop jumps. Conclusions: This review identifies potential contribute actions. Future research warranted this link via various tests protocols aimed at maximising neuromuscular adaptations.
