▼ Aim The aim of this study was to ascertain the effect of resisted sprint training in swimming on maximal swimming velocity and performance characteristics. The aim was also to examine how maximal swimming velocity is related to maximal swim power and maximal dry-land power. Method Eighteen competitive national level swimmers (9 male and 9 female; age: 18.3 ± 2.3 years, body mass: 72 ± 8.3 kg, height: 177.2 ± 4.6 cm, mean ± SD) were recruited to this study. Subjects were assigned to either resisted sprint training (RST) or unresisted sprint training (UST). Sprint training was performed two times per week during 6 weeks as 8x15m with a 2min send-off interval. RST performed sprint training using individualized load corresponding 10% of maximum drag load (L10), UST performed sprint training with no added resistance. A test-battery including dry-land strength assessment; maximal strength (MxS) and explosive strength (ExS), a timed 25m front-crawl swim and in-water force-velocity profiling was performed prior and following the training intervention. Maximal swim power (Pmax), maximum drag load (F0), theoretical maximum velocity (v0) and slope of force-velocity curve (SFv) was computed though force-velocity profiling. Results No significant within group differences occurred in neither RST nor UST following the 6-week intervention period in: swimming velocity, MxS, ExS, Pmax, F0, v0, and SFv. Strong correlations were found between swimming velocity and MxS (r = 0.75), ExS (r =0.82) and Pmax (r = 0.92). Conclusion Resisted sprint training in swimming using L10 did in the present study not elicit any improvements in maximal swimming velocity or examined performance characteristics. Resisted sprint training does not appear to be a superior method of improving swimming performance compared to unresisted sprint training. MxS, ExS and Pmax can be used as robust predictors of swim performance, however only Pmax was found to be casually related to swimming velocity.

▼ The aim of this study was to investigate the acute effect of sprinting with a sledge upon running performances in sprint. Thirty four (23 men and 11 women) secondary school and university students with athletics experience (age 20.21 ? 3.22yr, mass 65.04 ? 10.89 kg, 171.21 height ? 8.29 cm) participated in the study. The subjects performed this protocol in a two non-consecutive days, doing a rest day or easy training between the days of protocol. This protocol consisted of each participant perform each day a group of sprints, one day 7x60m alternating with normal and sledge running and the other day 7x60m of normal running. The weight of the sledge was 10% of body mass of each participant. It was found that training with the sledge or without it have the same training effect, thus there is no acute effect of sprinting with a sledge upon running performances in sprint. It is concluded that when an athlete reports that felt running faster after using sledge it seems ir is only a subjective feeling.
O objetivo deste estudo foi investigar os efeitos agudos nas performances das corridas de velocidade usando um trenó como método de treino de resistência e depois correndo normal sem resistência. Trinta e quatro (23 homens e 11 mulheres) do ensino secundário e estudantes universitários com experiência na modalidade de atletismo (idade 20,21 ? 3.22 anos, massa 65,04 ? 10,89 kg, altura 171,21 ? 8,29 cm) participaram no estudo. Os indivíduos realizaram este protocolo em dois dias não consecutivos, fazendo um dia de descanso ou de treino mais leve entre os dias de protocolo. Este protocolo consistiu em cada participante realizar cada dia um grupo de sprints, um dia alternando 7x60m com corrida de velocidade normal e com o trenó e o outro dia 7x60m apenas com corrida velocidade normal. O peso do trenó foi de 10% da massa corporal de cada participante. Verificou-se que o treino com o trenó ou sem ele teria o mesmo efeito de treino, portanto, não há um efeito agudo de correr com um trenó e após fazer corrida de velocidade normal. Conclui-se que quando um atleta diz que se sentiu mais rápido a correr após o uso do trenó, pode ser apenas um sentimento subjetivo.

▼ Abstract Aim The main purpose of this study was to investigate and compare the effects of a very heavy resisted sprint training regimen and a unresisted sprint training regimen on sprint, acceleration and jump performance in late pubertal adolescent football (soccer) players at mid- to post-PHV and >95% PAH. Method In total 27 male football players were recruited as volunteer participants. The participants had no previous experience with resisted sprint training. The participants were randomly assigned to either the resisted sprint (RST) (n=9) or unresisted sprint (UST) (n=10) training group. However, the grouping was matched based on the force-velocity (F-v) profiling. A control group (i.e. TAU group n=8) was matched with the experimental groups based on age and anthropometrics. The training was done twice a week for four weeks, consisting of either resisted or unresisted sprints. 24 of the original 27 participants could later be included for statistical analysis. During intervention the TAU group performed the regular team training with no additional stimuli from the researchers. Anthropometrics, sprint, acceleration and jump performance testing was tested pre- and post-training intervention. Results The four-week training intervention resulted in significant improvements of sprint- and acceleration for the RST-group. The improvements were 3,8% (±0.05) in T30, 4,2% (±0.06) in T20, 5,7% (±0.06) in T10, and 7,9% (±0.06) in the T5. The RST and UST groups also had significant improvements in both vertical and horizontal jump performance. Further there were several significant between group changes in both sprint and jump performance favoring the RST group over both the UST and TAU groups. Conclusion The conclusions are that in this population a very heavy RST regimen elicits improvements in sprint and acceleration performance whilst a UST regimen does not. Further, both the RST- and UST- training regimens elicit improvements in both vertical and horizontal jump performance. The improvements of the present study follow the pattern of previous studies in the field indicating a greater horizontal force generating ability. However, the improvements in the present study are larger than previously seen, indicating that this type of training might be extra beneficial to enhance sprint and jump performance in late pubertal adolescent athletes. The findings of the present study also contradict the typical recommendations of using light resistance loads (i.e. the 10% rule) when it comes to RST. Heavier loads, as in this case 103,5% of body weight on average, can indeed be used to produce sprint and acceleration gains in a late pubertal adolescent athlete population. The improvement in these short sprints (5-30m) versus the eventual performance decrease in longer sprints 40-70m (e.g. due to less effective maximal velocity phase) is a trade off which logically should be worthwhile for team…

▼ Novel
training methods such as backward running (BR) may promote unique adaptations to athletic performance compared to more traditional
training methods, like forward running (FR). While advocates have recommended BR for athletes over 18 years of age, no empirical information existed as to the utility of unresisted or
resisted BR in athletes around their adolescent growth spurt. This thesis sought to understand whether BR
training modalities promote positive adaptations in athletic performance among male youth athletes. An introduction and review provided an overview of BR and the natural development and trainability of speed in males around the time of adolescence, establishing the thesis framework and need for further investigation into the use of BR modalities.
To understand how unresisted and
resisted BR could be progressed in
training, two repeated cross-sectional studies investigated the reliability of unresisted and
resisted BR. In Chapter 3, it was found that after two habituation sessions, 34 high-school male athletes demonstrated good coefficient of variation for BR and FR (CV = 0.99% to 4.2%) and good to excellent intraclass correlational coefficients for BR and FR (ICC = 0.89 to 0.99). In Chapter 4, the load-velocity relationships of 21 high-school male athletes demonstrated that increases of ~13% (r2 = 0.99) and ∼15% (r2 = 1.00) body mass respectively, resulted in ∼10% decreases in running velocity during
resisted BR and FR compared to unresisted maximal effort velocities in the respective running direction (CV ≤ 7.2%; ICC ≥ 0.83 – 0.91).
Chapters 5 and 6 used matched-paired randomised control designs to determine the effectiveness of unresisted and
resisted BR
training on sprinting, jumping, and leg compliance measures in high-school male athletes. Chapter 5 compared the effects of eight weeks of progressively overloaded BR
training (BRT) versus volume matched FR
training (FRT) in 67 boys. The main findings were that a) all measures improved in both
training groups (p ≤ 0.01; effect size [ES] = 0.25 to 1.56), b) compared to the control group (CON), BRT improved all performance tests (p ≤ 0.001; ES = 0.63 to 1.59) and FRT enhanced sprinting and stiffness performance (p ≤ 0.01; ES = 0.45 to 1.29), and c) BRT demonstrated greater
training effects for
sprint and countermovement jump performance (p ≤ 0.05; ES = 0.54 to 0.76) compared with FRT. Chapter 6 compared the effects of eight weeks of progressively overloaded backward
resisted sprint (BRS)
training versus forward
resisted sprint (FRS)
training using equal loading strategies from 20% to 55% body mass in 115 boys. The main findings were that a) all performance metrics improved following BRS (p ≤ 0.01; ES = 0.22 to 0.79), b) all except 10 m performance enhanced following FRS (p ≤ 0.05; ES = 0.16 to 0.90), c) compared to the control group (CON), BRS resulted in improved performances for all tests except 10 m
sprint time (p ≤ 0.05; ES = 0.15 to 0.94) and FRS improved 10-20 m
sprint times, jump height, and stiffness (p ≤ 0.05; ES = 0.11 to 0.69),…

▼ The measurement of power-velocity and force-velocity relationships offers valuable insight
into athletic capabilities. The qualities underlying maximum power (i.e. optimal loading
conditions) are of particular interest in individualized
training prescription and the enhanced
development of explosive performance. While research has examined these themes using cycle
ergometers and specialized treadmills, the conditions for optimal loading during over-ground
sprint running have not been quantified. This thesis aimed to assess whether force-velocitypower
relationships and optimal loading conditions could be profiled using a sled-
resisted
multiple-trial method overground, if these characteristics differentiate between recreational
athletes and highly-trained sprinters, and whether conditions for optimal loading could be
determined from a single
sprint. Consequently, this required understanding of the friction
characteristics underlying sled-
resisted sprint kinetics. Chapter 3 presents a method of
assessing these characteristics by dragging an instrumented sled at varying velocities and
masses to find the conversion of normal force to friction force (coefficient of friction).
Methods were reliable (intraclass correlation [ICC]>0.99; coefficient of variation
[CV]<4.3%) and showed the coefficient of friction was dependent on sled towing velocity,
rather than normal load. The ‘coefficient of friction-velocity’ relationship was plotted by a
2nd order polynomial regression (R²=0.999; P<0.001), with the subsequent equation
presented for application in sled-
resisted sprinting. Chapter 4 implements these findings,
using multiple trials (6-7) of sled-
resisted sprints to generate individual force-velocity and
power-velocity relationships for recreational athletes (N=12) and sprinters (N=15). Data were
very well fitted with linear and quadratic equations, respectively (R²=0.977-0.997; P<0.001),
with all associated variables reliable (effect size [ES]=0.05-0.50; ICC=0.73-0.97; CV=1.0-
5.4%). The normal loads that maximized power (mean±SD) were 78±6 and 82±8% of bodymass,
representing an optimal force of 279±46 and 283±32 N at 4.19±0.19 and 4.90±0.18
m.s-1, for recreational and
sprint athletes respectively. Sprinters demonstrated greater absolute
and relative maximal power (17.2-26.5%; ES=0.97-2.13; P<0.02; likely), with much greater
velocity production (maximum theoretical velocity, 16.8%; ES=3.66; P<0.001; most likely).
Optimal force and normal loading did not clearly differentiate between groups (unclear and
likely small differences; P>0.05), and sprinters developed maximal power at much higher
velocities (16.9%; ES=3.73; P<0.001; most likely). The optimal loading conditions for
maximizing power appear individualized (range=69-96% of body-mass), and represent much
greater resistance than current guidelines. Chapter 5 investigated the ability of a single
sprint
to predict optimal sled loading, using identical methods to Chapter 4 and a recently validated
profiling technique using a single unloaded…

▼ Several
training options are available to produce specific adaptations depending on the requirement of the sport and the athlete. Specific strength exercises that closely mimic the sporting performance action enable overload and most likely optimise transference of adaptation to the sport/activity of interest. An example of this is wearable resistance (WR) (i.e. an external load attached to the body) which enables movement specific actions to be performed with additional resistance attached to various areas of the body. WR may be a potential
training option that allows athletes to train full body strength, speed and power exercises without compromising technique. Acute and longitudinal performance increases have been reported in jumping and
sprint running with WR; however, clarity is lacking when specifying the optimum load and load placement position. Previous WR research has involved weighted vests, hand held weights or loads attached to the thigh, ankle or foot. However, recent technological developments have enabled WR loading configurations to be attached to multiple areas of the body allowing greater functional dynamic actions to be performed. Therefore, the purpose of this thesis was to determine the acute kinematic and kinetic changes in vertical jump (VJ) and
sprint running performance with differing load magnitudes and load placements.
The aim of the first study was to determine the acute changes in kinematics and kinetics when an additional load equivalent to 3 or 6% body mass (BM) was attached to the upper or lower body during vertical jumping. Twenty athletic subjects performed the counter movement jump (CMJ), drop jump (DJ) and pogo jump (PJ) in a randomised fashion wearing no external load, 3 or 6% BM affixed to the upper or lower body (three jumps per condition). The main finding in terms of the landing phase was that the effect of WR was non-significant. However, landing relative vertical ground reaction force (Fv) tended to be higher with the same magnitude of lower WR compared to upper WR. With regards to the propulsive phase the main findings were that: 1) for both the CMJ and DJ, WR resulted in a significant decrease in jump height (CMJ: -12 to -17%, DJ: -10 to -14%), relative peak power (CMJ: -8 to -17%, DJ: -7 to -10%) and peak velocity (CMJ: -4 to -7%, DJ: -3 to -8%); 2) there was no significant effect of load placement; and, 3) PJ reactive strength index was significantly reduced (-15 to -21%) with all WR conditions. Consideration should be given to the inclusion of WR in sports where VJ?s are important components as it may provide a novel
training stimulus.
The purpose of the second study was to determine the acute changes in kinematics and kinetics when an additional load equivalent to 3% BM was attached to the anterior or posterior surface of the lower limbs during
sprint running. Nineteen male rugby athletes performed six 20 m sprints in a randomised fashion wearing no resistance or 3% BM affixed to the anterior or posterior surface of the lower limbs (two sprints per condition). No…
