    The Quantification, Autoregulation and Reliability of the Stomp as an Osteogenic Exercise
    (Gavin Publishers, 2021) Ryan, Chloe M. C.; Clissold, Tracey L.; Winwood, Paul W.
    Performing jump-landings may not be suitable for some individuals when programming for bone health. This study quantified a stomp exercise to determine its magnitude (body weight’s [BW’s]) and rate (body weights per second [BW∙s-1]) of strain among premenopausal women. Twenty healthy premenopausal women [Mean ±SD: 41.7±5.6y; 68.2±10.6kg; 165±5.5cm; 27.5±8.7% body fat] performed stomps on left and right legs at different rate of perceived exertions (RPE’s) (5 and 8) within the same session. The stomp RPE5 resultant magnitudes (3.08 and 2.89, BW’s) and rates of strain (199 and 180, BW∙s-1) for right and left legs (respectively), performed on a Kistler force plate, were similar to previously determined osteogenic thresholds (>3BW’s and >43 BW∙s-1 respectively). The stomp performed at RPE8, significantly (p < 0.001) exceeded stomps performed at RPE5 (4.58 and 4.42, BW’s and 344 and 333, BW∙s-1). The within-session reliability was good to excellent (0.68 to 0.89) for stomps performed at RPE5 and moderate to excellent (0.56 to 0.90) for stomps performed at RPE8. The stomp exercise achieves osteogenic thresholds thought pre-requisite for bone growth in premenopausal women and can be safely and reliably auto regulated by individuals for use in bone health programs where jump-landings may be contraindicated.

    The Importance of Recovery in Resistance Training Microcycle Construction.
    (Sciendo, 2024-04-15) Storey, Adam; Sousa, Colby; Zourdos, Michael; Helms, Eric
    Systemic resistance training aims to enhance performance by balancing stress, fatigue and recovery. While fatigue is expected, insufficient recovery may temporarily impair performance. The aim of this review was to examine evidence regarding manipulation of resistance training variables on subsequent effects on recovery and performance. PubMed, Medline, SPORTDiscus, Scopus and CINAHL were searched. Only studies that investigated recovery between resistance training sessions were selected, with a total of 24 articles included for review. Training to failure may lengthen recovery times, potentially impairing performance; however, it may be suitable if implemented strategically ensuring adequate recovery between sessions of similar exercises or muscle groups. Higher volumes may increase recovery demands, especially when paired with training to failure, however, with wide variation in individual responses, it is suggested to start with lower volume, monitor recovery, and gradually increase training volume if appropriate. Exercises emphasising the lower body, multi-joint movements, greater muscle recruitment, eccentric contractions, and/or the lengthened position may require longer recovery times. Adjusting volume and frequency of these exercises can affect recovery demands depending on the goals and training logistics. Daily undulating programming may maximise performance on priority sessions while maintaining purposeful and productive easy days. For example, active recovery in the form of training opposing muscle groups, light aerobic cardio, or low-volume power-type training may improve recovery and potentially elicit a post activation potentiation priming effect compared to passive recovery. However, it is possible that training cessation may be adequate for allowing sufficient recovery prior to sessions of importance.

    An Inclusive Workplace Framework: Principles and Practices for Work-Integrated Learning Host Organizations
    (International Journal of Work-Integrated Learning, 2024-03-25) Fleming, Jennine; Hay, Kathryn
    Work-integrated learning (WIL), as an educational approach, is facilitated through relationships between Higher Education Institutions (HEIs) and external ‘host’ organizations. Responsible host organizations should recognize that students undertaking WIL come from a range of different cultures, socio-economic backgrounds, and have varying academic, physical, and other capabilities. An inclusive workplace will seek to facilitate a positive and rewarding experience for all WIL students. Recent WIL literature has seen a strong focus on inclusive access to WIL. This article examines key elements that can contribute to host organizations providing an inclusive environment for students. Socio-cultural theories related to learning in the workplace are used as a theoretical lens. An Inclusive WIL Workplace Framework is proposed, highlighting principles, practices, and supervisor and co-worker characteristics, that can be utilized by workplaces to assess their inclusivity and address any gaps, and by students to understand the expectations of HEIs on host organizations.

    Durability of the Moderate-to-Heavy-Intensity Transition Is Related to the Effects of Prolonged Exercise on Severe-Intensity Performance
    (Springer Science and Business Media LLC, 2024-03-28) Hamilton, Kate; Kilding, Andrew E; Plews, Daniel J; Mildenhall, Mathew J; Waldron, Mark; Charoensap, Thanchanok; Cox, Tobias H; Brick, Matthew J; Leigh, Warren B; Maunder, Ed
    Purpose Power output at the moderate-to-heavy-intensity transition decreases during prolonged exercise, and resilience to this has been termed ‘durability’. The purpose of this study was to assess the relationship between durability and the effect of prolonged exercise on severe-intensity performance, and explore intramuscular correlates of durability. Methods On separate days, 13 well-trained cyclists and triathletes (V̇O2peak, 57.3 ± 4.8 mL kg−1 min−1; training volume, 12 ± 2.1 h week−1) undertook an incremental test and 5-min time trial (TT) to determine power output at the first ventilatory threshold (VT1) and severe-intensity performance, with and without 150-min of prior moderate-intensity cycling. A single resting vastus lateralis microbiopsy was obtained. Results Prolonged exercise reduced power output at VT1 (211 ± 40 vs. 198 ± 39 W, ∆ -13 ± 16 W, ∆ -6 ± 7%, P = 0.013) and 5-min TT performance (333 ± 75 vs. 302 ± 63 W, ∆ -31 ± 41 W, ∆ -9 ± 10%, P = 0.017). The reduction in 5-min TT performance was significantly associated with durability of VT1 (rs = 0.719, P = 0.007). Durability of VT1 was not related to vastus lateralis carnosine content, citrate synthase activity, or complex I activity (P > 0.05). Conclusion These data provide the first direct support that durability of the moderate-to-heavy-intensity transition is an important performance parameter, as more durable athletes exhibited smaller reductions in 5-min TT performance following prolonged exercise. We did not find relationships between durability and vastus lateralis carnosine content, citrate synthase activity, or complex I activity.

    Variations in Strength-Speed-Power Performance Across the Season: Do True Changes Occur in Elite Rugby Players?
    (Termedia Sp. z.o.o., 2024) Loturco, Irineu; Bishop, Chris; Zabaloy, Santiago; Moura, Túlio BMA; Ramos, Maurício S; Pereira, Lucas A; McGuigan, Michael
    This study aimed to determine, through the use of a highly sensitive statistical tool, whether real changes in performance were present; and compare the rates of meaningful variations in strength, speed, and power parameters at different time-points during the competitive season in national team rugby players. Thirtytwo players were assessed 5 times across the season using the following tests: squat jump and countermovement jump tests; 30-m sprint velocity; and one-repetition maximum (1RM) in the half-squat and bench-press exercises. A repeated measures analysis of variance was conducted to test for differences between successive time-points. Individual coefficients of variation values were used to set target scores for post measurements and examine whether changes in performance parameters were greater than the natural test variance, thus providing an indication of whether “true changes” occurred. No significant changes were detected in the vertical jump height, 1RM measures, and sprint velocity and momentum throughout the 11-month period (P > 0.05). True changes occurred much more frequently for strength-power measures than for sprint velocity and momentum. Elite rugby union players did not exhibit significant variations in neuromuscular performance across the competitive period, when a group-based analysis was conducted. However, at the individual level, “true changes” in strength-power- (but not in speed-) related qualities were consistently observed over the competitive season.
