Adjusted saddle position counteracts the modified muscle activation patterns during uphill cycling
Borut Fonda, Andrej Panjan, Goran Markovič, Nejc Šarabon, 2011, original scientific article

Abstract: The main aim of this project was to study muscle activity patterns during steep uphill cycling (UC) (i.e., with a gradient of 20%) with (1) normal saddle geometry and (2) with adjusted saddle position ASP (i.e., moving the saddle forward and changing the tilt of the saddle by 20%). Based on our preliminary case study, we hypothesized that: (1) during 20% UC muscle activity patterns would be different from those of level cycling (LC) and (2) during 20% UC with ASP muscle activity patterns would resemble those of LC. Twelve trained male cyclists were tested on an electromagnetically braked cycle ergometer under three conditions with the same work rate (80% of maximal power output) and cadence (90 rpm): level (LC), 20% UC and 20% UC with ASP. Electromyographic signals were acquired from m. tibialis anterior (TA), m. soleus (SO), m. gastrocnemius (GC), m. vastus lateralis (VL), m. vastus medialis (VM), m. rectus femoris (RF), m. biceps femoris (BF) and m. gluteus maximus (GM). Compared to LC, 20% UC significantly modified both the timing and the intensity of activity of the selected muscles, while muscles that cross the hip joint were the most affected (RF later onset, earlier offset, shorter range of activity and decrease in peak amplitude of 34%; BF longer range of activity; GM increase in peak amplitude of 44%). These changes in EMG patterns during 20% UC were successfully counteracted by the use of ASP and it was interesting to observe that the use of ASP during 20% UC was perceived positively by all cyclists regarding both comfort and performance. These results could have a practical relevance in terms of improving performance during UC, together with reducing discomfort

Effects of whole-body cryotherapy on recovery after hamstring damaging exercise
Borut Fonda, Nejc Šarabon, 2013, original scientific article

Abstract: The purpose of this study was to examine the effects of whole-body cryotherapy (WBC) on biochemical, pain, and performance parameters during the 5-day recovery period after damaging exercise for hamstrings. Participants completed a bout of damaging exercise for the hamstring muscles on two separate occasions (control and experimental condition) separated by 10 weeks. During the control condition, subjects received no treatment after the damaging exercise. The experimental condition consisted of WBC everyday during the recovery period. WBC included single 3-min daily exposures to low temperatures (-140 to -195 °C) in the cryo-cabin. During the recovery period, subjects were tested for biochemical markers, perceived pain sensation, and physical performance (squat jump, counter movement jump, maximal isometric torque production, and maximally explosive isometric torque production). Majority of the observed variables showed statistically significant time effects (P < 0.05) in control group, which indicates the presence of muscle damage. Significant interaction between the control and WBC condition was evident for the rate of torque development (P < 0.05). Pain measures substantially differed between the WBC and the control condition after the exercise. Results of this study are not completely supportive of the use of WBC for recovery enhancement after strenuous training

Merilni sistem za vrednotenje živčno-mišičnih funkcij trupa
Andrej Panjan, Borut Fonda, Nejc Šarabon, Matej Voglar, 2013, original scientific article

Abstract: Bolečina v križu (BVK) je najpogostejši zdravstveni problem gibalnega aparata današnje populacije. Pri osebah z BVK je opaziti številne spremembe v živčno-mišičnih funkcijah trupa. Kljub temu da je etiologija BVK zelo kompleksna in pogosto tudi psihosomatsko pogojena, je za uspešno preventivo/rehabilitacijo potrebno razumevanje biomehanskih značilnosti, ki sepogosto pojavljajo pri osebah z BVK. Objektivno vrednotenje gibalnih funkcijtrupa omogoča prepoznavo sprememb, ki so lahko vzrok in/ali posledica BVK. Kljub številnim študijam, ki dokazujejo spremembe v različnih gibalnih funkcijah trupa, je objektivno vrednotenje teh pogosto le v raziskovalnih študijah, ne pa v klinični praksi. Namen tega članka je predstaviti tehnične lastnosti celostnega integriranega merilnega sistema za veljavno in objektivno vrednotenje živčno-mišičnih funkcij trupa, ki je bil razvit v sklopu aplikativnega raziskovalnega projekta, ki predstavlja vzoren primer sodelovanja med univerzo in gospodarstvom. Dodatno je empirično in grafično predstavljena študija primera ene celotne meritve na mladi zdravi osebi. Na koncu članka so predlagane praktične rešitve za zdravstvene in vadbene ustanove pri obravnavi bolnikov z BVK.
