“…This observation may be related to the fact that the test protocol approximates more closely to muscle contraction dynamics and contraction times associated with the sprinting tests. The results from this study are in agreement with previous work [26,27] which suggests that active muscle tissue should be used when determining resistive forces used during high-intensity cycle ergometry.…”

This study investigated the relationship between performance measures of the lower-limb and repeated shuttle-sprint ability (RSSA) in elite adolescent handball players. Twenty-two male handball players (age: 17.7 ± 0.3 years) participated in the study. Subjects underwent measurements of lower-limb maximal strength (1-RM half back squat), explosive power (force-velocity test), jumping ability (squat and counter-movement jumps), sprinting velocities over the first step (V S ) and the first 5 m (V 5 ) of a 15 m sprint, and Yo-Yo Intermittent Recovery Test, Level 1. The players were tested for RSSA using a protocol of 6 repetitions of maximal 2 x 15-m shuttle sprints with 180° turns (~6 s) departing every 20 s. RSSA results were evaluated in three ways: best time in a single trial (RSSA best ), decrement (RSSA dec ) and total time (RSSA TT ). The correlations of RSSA with the assorted fitness measures varied considerably. The RSSA TT and RSSA dec were positively associated with 1-RM half back squat (r = 0.78 and r = 0.68 respectively; p< 0.01). Significant correlations were also found between RSSA TT and Reviewer:Michael Chia (Nangyang Technological University, Singapore) Consequently, the assessment and development of traditional fitness parameters, such as explosive strength and anaerobic power, is a common handball practice, especially during the in-season competitive period [6,7]. Based on game time-motion analysis, RSA has strong ecological validity and is believed to be an important fitness component of many team sports, including handball (28, 32). For this reason, several different tests are used by sport scientists and coaches to assess the physical performance of handball players [1,6,7]. These tests include the assessment of sprint and repeated shuttle-sprint ability (RSSA), and muscular power [1]. The ability to recover and reproduce performance in subsequent sprints, termed repeated-sprint ability, is believed to be a specific fitness requirement of handball and other team sport athletes [1,8]. Therefore, the relevance of RSSA tests for handball is mainly based on their ecological validity as these tests require the repetition of handball-specific high-intensity activities (i.e., repeated sprints with or without directional changes) and similar metabolic requirements [8]. Therefore, in handball it seems logical to evaluate the athletes' ability to repeatedly perform intense exercise and with that his/her potential to recover from intensive efforts. The relevance of RSA tests for handball is mainly based on their perceived ecological validity and the belief that these tests mimic the demands of competitive play. Replicating game demands during repeated-sprint sequences appears crucial regarding testing and training specificity [5,9]. In addition, handball-specific RSSA test protocols have been recently presented [1,4,10].Because RSSA is considered a critical factor for performance in handball, strength and conditioning coaches are interested in how to develop this quality in their athletes.

“…However, there are limitations to the use of the RPE scale in the current study, as the RPE scale is designed for use during (or immediately following) continuous exercise at a constant intensity and may not be a valid measure of exertion during interval based exercises, especially when values are given retrospective of the most intense exercise, as was the case in this study. RPE values obtained in this manner may underestimate exertion during the sprints; indeed, other studies where RPE has been obtained following a 20 second all out sprint have reported higher values of ~16-18 (Baker et al 2001;Gearhart et al 2005). However, we were interested in gaining an exertion measure to characterise our entire training intervention and our subjects were asked to consider the whole 10 minute exercise session when giving their ratings.…”

High-intensity interval training (HIT) has been proposed as a time-efficient alternative to traditional cardiorespiratory exercise training, but is very fatiguing. In this study we investigated the effects of a reduced-exertion HIT (REHIT) exercise intervention on insulin sensitivity and aerobic capacity.Twenty-nine healthy but sedentary young men and women were randomly assigned to the REHIT intervention (men: n=7, women n=8) or a control group (men n=6; women n=8). Subjects assigned to the control groups maintained their normal sedentary lifestyle, whilst subjects in the training groups completed 3 exercise sessions per week for 6 weeks. The 10-min exercise sessions consisted of low intensity cycling (60 Watts) and one (1 st session) or two (all other sessions) brief 'all-out' sprints (10 s in week 1, 15 s in weeks 2-3 and 20 s in the final 3 weeks). Aerobic capacity (V O2peak) and the glucose and insulin response to a 75-g glucose load (OGTT) were determined before and 3 days after the exercise program. Despite relatively low ratings of perceived exertion (RPE: 13±1), insulin sensitivity significantly increased by 28% in the male training group following the REHIT intervention (P<0.05). V O2peak increased in the male training (+15%) and female training (+12%) groups (P<0.01). In conclusion we show that a novel, feasible exercise intervention can improve metabolic health and aerobic capacity. REHIT may offer a genuinely time-efficient alternative to HIT and conventional cardiorespiratory exercise training for improving risk factors of T2D.

“…That is, P/LBM is a constant for equally trained athletes of both genders, Baker et al (2001), Maud and Schutz (1986), Sveinsson et al (2009) and Taguchi et al (2011). A fraction of the generated power, P e, is then applied to the centre of gravity of a runner with body mass m, where e is the efficiency less than or equal to one, depending on a combination of coaching, technique and equipment.…”
