The possible direct role of exercise intensity and duration on leptin concentrations is conflicting. The aim of this study was to evaluate the acute effects of high intensity interval (HIIE) and moderate intensity continuous (MICE) exercise on plasma leptin response. Seven young volunteers underwent three tests: 1) a treadmill graded exercise test to identify running peak velocity (PV); 2) HIIE: 5 × 2 min work bouts at 90% of PV, interspersed by 2 min of passive recovery and; 3) MICE: 30 min at 70 % of PV. Blood samples were drawn for the assays of leptin before and 30 minutes after HIIE and MICE. A 2-way repeated measures ANOVA showed a significant main effect of time [F(1,6) =17,52; p=0,006], no significant effect of condition (type of exercise) (F(1,6) = 0,16; p = 0,68) and no significant interaction (condition × time) (F(1,6)= 0,48, p=0,51). Leptin decreased 30 min after HIIE (t= 2,95, p=0,025) and MICE (t=4,18; p=0,005). There was no difference between the HIIE and MICE conditions immediately after exercise (t=0,90; p=0,40). After HIIE and MICE, leptin decreased in the same magnitude. It appears that both exercise modalities result in physical stress which is sufficient to improve short-term leptin sensibility.

Several studies have provided evidence for the importance of motivation in motor learning. The present study investigates whether providing positive feedback as statements praising good performance would benefit children’s motor learning when compared to a no-praise condition. Thirty 10-year-old children divided into two groups—positive feedback (PF) and control—learned to ride a pedalo over a seven-meter distance in the shortest time possible. Participants performed 20 practice trials and received feedback on their movement time following each trial. However, only the PF group received feedback acknowledging good performance after each trial block. After 24 hours, both groups performed learning tests without any feedback. Questionnaires (Intrinsic Motivation Inventory) were applied to measure participants’ motivational levels. The results show substantial improvements in performance during practice and high levels of intrinsic motivation, sustained across days, in both groups. Differences between groups in motivation, performance, and learning were not found. These results demonstrate that riding a pedalo in the shortest time possible constitutes an intrinsically motivating task in children, whose learning is not altered by the provision of positive feedback statements acknowledging good performance, possibly by a motivational ceiling effect. The findings indicate that task-inherent motivational characteristics can moderate positive feedback learning effects in children. Future studies could measure other motivational constructs, such as learner’s persistence in practicing the task, or could include post-failure measures that may reveal differences in children’s capacity to cope with errors. Differences between groups would demonstrate potential benefits of providing positive feedback praising performance in children that were not captured in the present experiment, even on the learning of inherently motivating tasks.

The maximal running speed (MRS) achieved in the 30-15 International Fitness Test (30-15IFT) is widely used to prescribe high-intensity interval training (HIIT). The 30-15IFT can be performed in either 40- (30-15IFT-40) or 28-meters (30-15IFT-28) length. Objectives: The aim of this study was to evaluate the MRS achieved in the 30-15IFT-40 and the 30-15IFT-28. Methods: Fifty U-18 players from different sports (handball: n=19, soccer: n=19, tennis n=12) attended two testing sessions. Results: MRS did not differ between the 30-15IFT-40 and the 30-15IFT-28 in either handball or soccer players. However, tennis players showed significantly greater MRS values in the 30-15IFT-28 than in the 30-15IFT-40 (20.80±1.87 vs 20.05±2.09 km·h-1; p = 0.030; ES = 0.38). In addition, tennis player showed significant greater MRS in the 30-15IFT-28 (20.80±1.87 km·h-1) than both handball (18.58±1.13 km·h-1; p < 0.001; ES = 1.53) and soccer players (18.74±0.93 km·h-1; p = 0.001; ES = 1.47). Conclusions: The different MRS values in the 30-15IFT-40 and the 30-15IFT-28, entail significant practical implications for HIIT prescription in tennis players.

The aim of the present study was to examine the relationships between internal training loads (TL) (Banister, Edwards Training-Impulse (TRIMP), session RPE (s-RPE)) and external TL (Total distance (TD), high speed distance (HSD), high metabolic distance (HMD) in amateur soccer players. Nine male amateur soccer players (age = 28.74±5.2 years; height 173.74± 8.04 cm; weight 72.73±5.5 kg) voluntarily participated in the study. Individual field-based training sessions were monitored over 8 weeks. The results showed that there were moderate and very large correlations between s-RPE and both Edwards and Banister’s TRIMP (respectively, r = 0.42-0.86; r= 0.45-0.85). Additionally, from large to nearly perfect correlations were observed between the HR-based methods (r= 0.58-0.98). We also found moderate to very large correlations between s-RPE and HMD and large to nearly perfect correlations between HR-based TL methods and HMD. Correlations between internal load and external load parameters was weaker in HSD than TD. In the light of the results of the current study, internal and external loads should not be used interchangeable and HMD seems to be appropriate to monitor TL in soccer players because its equations include both speed and acceleration values.

The purpose of this study was to examine the acute effects of a dynamic warm-up including hip mobility exercises on sprint, agility and vertical jump performance. Twenty well trained male collegiate athletes (age = 20 ± 1.1 years; height = 178.3 ± 8.8 m; body weight = 72 ± 5.6 kg) volunteered for the study. All subjects completed two individual testing sessions on two non-consecutive days. On the first trial day, after 15 minutes of a simple dynamic warm-up, 30-m sprint test, Illinois agility test and countermovement jump test were performed at the control condition. On the second trial day addition to dynamic warm-up, subjects performed 6 hip mobility (6 min) exercises before tests. A paired samples t-test revealed a significant difference (p = 0.013) on sprint performance when comparing simple dynamic warm-up with a dynamic warm-up including hip mobility exercises. But no significant difference was found for agility (p = 0.071) and jump performances (p = 0.823). It can, therefore, be concluded that has a significant effect on sprinting performance whereas it has no significant effect on agility and vertical jump performance.

It is well-known that visual information is essential for anticipation in table tennis but it not clarified whether auditory cues are also used. Therefore, we performed two in-situ studies, in which novices (study A) and advanced players (study B) responded to strokes of a real opponent or a ball machine by returning with forehand counters (study A) and forehand top spins (study B) to a given target area on the table. We assessed the parameters “hit quality” and “subjective effort”. In study A, we provided four conditions: normal, a noise-cancelling headphone and earplugs to dampen auditory information, other noise-cancelling headphones and earplugs to remove almost all environmental sounds, and the same head-phones with additional bright noise to remove all sounds. In study B, we performed three tests (irregular play and regular play with an opponent and response to regular balls of a ball machine) under two conditions: normal and noise-cancelling headphones with the additional bright noise. In both studies, no significant differences between all conditions for “hit quality” and “subjective effort” (all p>0.05) were found. We conclude that auditory information, as well as their volume, have no influence on the hit quality in table tennis for novices and advanced players.
